SEG Newsletter 101 2015 April

INTRODUCTIONThe eastern part of what has become known as the Arabian-Nubian Shield (e.g., Johnson and Woldehaimanot, 2003), particularly Saudi Arabia, has been extensively explored since the 1970s, with numerous discoveries of deposits of a variety of commodities including gold, silver, copper, molyb-denum, zinc, tin, tungsten, tantalum, and uranium. By contrast, the western Arabian-Nubian Shield, here defined as that segment west and south of the Red Sea (Figure 1), has received less explora-tion attention due to a combination of factors, including that, until recently, exploration and mining legislation required further clarity. From a geologic standpoint, the western Nubian Shield is a high-impact frontier gold oppor-tunity, with discoveries of >45 Moz gold equivalent in the last two decades. Historical gold occurrences and out-cropping mineralization abound, there has been and continues to be extensive mining of alluvial gold (probably several Moz gold), particularly in Ethiopia (e.g.,

Tadesse et al., 2003), and ancient primary gold mining was carried out from the Pharaonic period in Egypt, commencing 3000 BC, through to the Roman period and thereafter, with approximately 0.5 to 0.6 Moz of high-grade gold produced (Klemm et al., 2001).

Current mining legislation in the region has now afforded sufficient certainty to attract exploration to Egypt, Sudan, Eritrea, and Ethiopia, with accelerated discovery of significant gold resources in both oro-genic gold, including the emerging giant Sukari deposit in Egypt, and volcanogenic massive sulfide (VMS) deposit styles. Additionally, giant potash deposits have been discovered in the Afar Depression of Ethiopia by

companies such as Allana Potash and also by South Boulder Mines at Colluli in Eritrea. Recently, Stra-tex and Thani Ashanti

SEG PUBLICATIONSSales revenue of SEG publications decreased significantly relative to 2013 and consisted overwhelmingly of bookstore orders (85%), the remainder coming from exhibit booth sales. Mem-ber sales made up about 80% of total publication sales. Revenue is attributed to sales from our listing of 47 different Guidebooks, 17 Reviews volumes, 18 Special Publications, 11 Monographs, 9 Compilation Series, 24 Videos, 7 Conference Series volumes, as well as Economic Geology and SEG Newsletter back issues, the Dummett DVD, Eco-nomic Geology 100th Anniversary Volume, Anniversary Collection DVD (100th, 75th, and 50th anniversary volumes), SEG 75 Years of Progress: 1920–1995, and Tables for Determination of Opaque Miner-als (CD). The most popular publication in overall unit sales remains Special Publication no. 16, Geology and Genesis of Major Copper Deposits and Districts of the World: A Tribute to Richard H. Sillitoe, edited by Hedenquist, Harris, and Camus, followed by Special Publication 18, Building Exploration Capability for the 21st Century, edited by K.D. Kelley and H.C. Golden. Downloads of e-docs were somewhat lower than in 2013.

Four scheduled issues of the SEG Newsletter and eight issues of Eco-nomic Geology were released through

Summary of Activities for the Year 2014 (continued). . . from page 5


December. Compilation 8, on Mexico ore deposits, and Compilation 9, on the Northern Cordillera, were released during the second quarter, Special Publication 18 was published for the Keystone conference (the conference generated six field trip guidebooks published or revised), and Special Pub-lications 16 and 17 were reprinted. SEG e-books became available through Geo-ScienceWorld for participating libraries.

International shipping rates using USPS increased by 3–3.5%, contributing to increases in dues and subscription rates.

Subscription by members to the Geofacets Millenium Edition remained strong in 2014 and there was an increase in the number of corporate subscribers.

MARKETINGSEG exhibited at the following meet-ings during 2014: AME BC Roundup, Vancouver, Canada; PDAC, Toronto, Canada; SIMEXMIN 2014, Ouro Preto, Brazil; Goldschmidt 2014, Sacramento, California, USA; International Min-eralogical Association (IMA 2014), Sandton Convention Center, Gauteng, South Africa; SEG Keystone 2014 - Keystone, Colorado USA; XVII Peruvian Geological Congress, Lima, Peru; GSA 2014 Annual Meeting, Vancouver BC, Canada; American Exploration and Mining Association Meeting, Reno, NV, USA (formerly Northwest Mining Association). Marketing efforts were

focused on courses and field trips that form part of the Education and Training Curriculum, but especially on the SEG 2014 Conference at Keystone. Advertis-ing media included the SEG Newsletter, member e-broadcasts, the SEG website, social media sites and the stand-alone SEG 2014 Conference website. Adver-tisements were placed in third-party media such as The Northern Miner, Mining Journal, Mineweb, and Geospec-trum, with additional promotions run by several associated societies and orga-nizations. On the social media front, SEG launched an interactive economic geology and Society trivia question section in its e-News editions and on Instagram. The rapid growth of the SEG LinkedIn group to 9,000 members has probably been fueled by employment circumstances during the downturn in the minerals industry.

The SEG 2015 Hobart Conference web-site was initiated and all future conference sites are planned to be built, maintained, and archived in-house. Major software upgrades/updates included iMIS (associa-tion management software), Marketplace (online store, contributions, and dues), and web services.

EDUCATION AND TRAINING CURRICULUMSEG and SEGF organized and/or spon-sored 16 courses/workshops and 11 field trips during 2014. A preliminary course prospectus/catalog for 2014 was posted on the SEG website on February

28, 2014. Audiovisual equipment in the SEG Course Center is being upgraded in a phased approach.

SEG OFFICE ADMINISTRATIONThe office staff complement of twelve persons remained unchanged. This included two staff on a part-time basis, effectively adding up to 11.5 full-time equivalents. In addition, two contract workers were engaged in the copyediting of manuscripts for publication and a fur-ther contract worker continues to fill the role of Program Coordinator in the Edu-cation and Training Committee. Tem-porary summer workers were engaged in various tasks related to publications, administration, and logistics. 1

As indicated in my previous column, a major objective of our Society is to offer professional development opportunities to members at all stages of their career advancement. In 2015, SEG once again has put together an extensive program which was presented in the January Newsletter (p. 50–51). It includes a group of high-caliber traveling lecturers under the Distinguished, Thayer Lindsley, International Exchange, and Regional VP lecturer programs. The talks they have offered cover several deposit types, with a focus ranging from ore-forming pro-cesses, to exploration, and metallogeny and tectonic evolution of an important part of Africa. Another key component of this program is an elaborate curric-ulum of short courses, workshops, and field trips delivered by recognized experts at diverse locations around the world. An updated brochure of the 2015 program is now available on the SEG website.

This year’s program, however, will obviously culminate with the SEG 2015 Conference at Hobart, Tasmania, in late September. The organizers have devel-oped a very attractive program of talks, field trips, and short courses around the theme, World-Class Ore Deposits: Discovery to Recovery, a topic which should satisfy the interests of the full spectrum of SEG members, including those specializing in metallurgy. A novelty of the program consists of triplets of coordinated talks (“trifecta”) on the discovery, geology, and geometallurgy of four world-class deposits to illustrate industry best prac-tices in these areas and their successful implementation.

As we would all recognize, “geol-ogy” is the critical foundation of much of what we do as economic geologists across this spectrum, from discovery to geometallurgy. For example, the devel-opment of robust geological models, supported by a good understanding of geometry and local controls on mineral-ization, is absolutely critical to building realistic resource models which are, in turn, critical to successful mining. At the other end of the spectrum, thor-ough geological understanding of an area under investigation, coupled with sound exploration concepts, is just

as critical to discovery. Achieving the required geological understanding at the scale of interest remains fundamentally based on the acquisition and interpre-tation of basic geological observations from outcrops and drill core, enhanced through integration with other geosci-entific datasets and through familiarity with the relevant deposit models and ore-forming processes.

An obvious question is how can we acquire the required practical observa-tion and interpretation skills? We have all heard that, all others factors being equal, the best geologists are those who have seen the most rocks. This is cer-tainly true but it is also about knowing what to look for in the rock to establish its geological context, especially its place in space and time. In other words, it is about linking one’s own field-based observations with relevant geological concepts, knowledge of processes, and an accurate geologic map (or section) at the scale of interest. This practical geological

know-how is not gained overnight and comes only with dedication, experi-ence, and as much field exposure as possible.

For students, this pro-cess starts with making the best of any field geology

components still offered by academic institutions, seeking field-based summer employment or internships, with a map-ping component if available, and partic-ipating in as many external field trips as possible. At the professional level, most companies see the value of developing the skills (especially field-based) of their younger geoscientists, and an increasing number have their own formal training programs for recent graduates. Even in the absence of such programs, young geologists should link with colleagues who possess significant field experience for guidance and mentoring, and should consider organizing informal field trips to other deposits in their work areas. Employers can accelerate this learning process by supporting their young geol-ogists to attend relevant field trips and field mapping courses, and by teaming up young geologists with experienced consultants who are increasingly used for mapping and structural interpre-tation work by many companies. SEG is well aware of the importance of

field-based skills and puts significant effort into offering a range of field trips and practical short courses, as well as providing funds to Student Chap-ters for field-based activities.

Once in the field, we all should max-imize the learning opportunity. Even as a relatively experienced geologist, I still make a conscious effort to learn some-thing new every time I go to the field. The focus should not be only on the deposit-scale geology but also on the geologic setting at the local and district scales, an aspect not always adequately emphasized. For example, are there any district-scale structural or stratigraphic controls on the deposit location? Where does the deposit fit in the geological evolution of an area? In organizing meaningful field trips, some focus should be put on demonstrating the geological setting of the district through a review of key field localities, which can often be done with the assistance of local government geologists or univer-sity professors. I generally stick small versions of regional maps or sections in my notebook for reference in the field and for discussions about the geological context with others. In terms of learn-ing what to look for in the rocks, one should ask a lot of questions—such as the following: what is the most import-ant feature to focus on in this outcrop or drill hole and how does it relate to the hydrothermal architecture of the mineralized system or to its geological context?

To borrow a message from Judith Kinnaird’s presidential address, geology is a life-long learning process. With this field-based geological focus in mind, I encourage each of our members to make the best of the professional develop-ment opportunities offered by SEG this year, and for those in management posi-tions to support and encourage partici-pation of some of their young geologists where and when practical. In closing, I would like to acknowledge the incred-ible dedication and efforts of the SEG staff in Littleton, the many volunteers, and the presenters who all make such a program possible. 1

Professional Development Opportunities and Their Geological Underpinning

François roBert

SEG President 2015

. . . practical geological know-how is not gained overnight and comes only with dedication, experience, and as much field exposure as possible.


The Board of Trustees of the Society of Economic Geologists Foundation (SEGF) typically has two opportunities to meet each year. The first is in Toronto each March, directly prior to the Prospector and Developers Association of Canada (PDAC) annual convention, and the second is in September, associated with a major SEG Conference—which will be in Hobart this year. I recently had the pleasure to chair my first Trustees meeting in Toronto and would like to provide an update on SEGF activities, plans, and challenges, as well as offer some thoughts on the general condition of our notoriously cyclical industry.

The recent meetings of the SEG Coun-cil and of the Trustees provided excellent summaries of how the Society is faring during the challenging times of an extended industry downturn. The SEG and the SEGF are both in remarkably good financial condition and continuing to seek new opportunities to provide support to members and increase the footprint of the Society. The strength of the SEG is due in large part to the dedi-cated efforts of Executive Director Brian Hoal and the outstanding staff at the Lit-tleton SEG headquarters, as they support a strong cast of volunteer professionals who contribute to the Society.

After several years of strong, often double-digit, annual growth, the membership of the SEG has reached a plateau over the past two years, with about 7,500 members. Despite ini-tiatives to retain members, including a new reduced-rate membership for recent graduates, membership decreased slightly over the past year after several decades of steady increase. This poten-tially presents some challenges in the near term, particularly when we look at the demographics of our membership. This past year there was continued strong growth in the number of new student members, with a net increase of 113 students to a new high of 1,770. Student members now comprise 24% of the total membership of the SEG, with 83 student chapters in 27 countries.

The principal role of the SEGF is to raise funds to support educational and career development opportunities for members, with a particular emphasis on students. In 2014, the SEGF received 123 research grant proposals and funded

49 research grants ($127,000) and 23 graduate student fellowships ($175,000). The SEG Canada Foundation (SEGCF) funded 19 student grants (CDN$68,000), 5 student fellowships (CDN$30,000) and 25 undergraduate thesis scholarships (CDN$25,000). When combined with student field trips and other activities, the SEGF and SEGCF provided more than $500,000 in support to student members during 2014. Total expen-ditures for the SEGF were $669,711 in 2014, including a prudent amount (16.6%) for overhead G&A expenses.

Funding to pay for SEGF activities comes from two principal sources: contributions to the Foundation and investment income from SEGF’s financial assets. The SEGF received contributions totaling $347,053 in 2014. This amount was down sharply from record contribu-tions of $518,720 in 2013, but similar to amounts received in 2011 and 2012. We continue to see the role of corporate con-tributions shrinking ($151,000) relative to encouragingly strong support from individual members ($196,034). How-ever, it should be noted $90,000 of the latter came from one anonymous donor, with no indication that this support will continue to be available in future years.

Although investment income of $167,773 helped to offset some of the difference, the SEGF still experienced a net financial loss of approximately $220,000 in 2014. To put this in better context, the financial assets of the SEGF totaled $4,556,098 at the end of 2014, so the loss last year amounted to approximately 5% of total finan-cial assets. We find ourselves facing a challenging situation for the immedi-ate future, as an increasing number of student members will continue to seek financial support while most potential corporate donors may not in a posi-tion to help with sustaining multiyear pledges. Although the situation is not ideal, the SEGF has the financial base to sustain several more years of similar losses until we bridge through to better times in the industry. The Fundraising Committee, under the leadership of Past President Don Birak, will be coordinat-ing efforts with the SEG and the SEGCF to reach out to all corporate and indi-vidual members to help minimize the erosion of financial assets and ensure we

can continue with the wide variety of programs available.

This brings us to the ques-tion—when will we see the end of the current sus-tained downturn in our industry? The annual PDAC conference provides a great opportu-nity to judge exploration activity and this year revealed an increasingly bleak scenario. By many measures exploration is now down by more than 50% from only a few years ago. Although it is of little comfort to the unemployed, the depth of this downturn only increases the likelihood that we will see a strong resurgence in exploration activity in the not-too-distant future. Picking the darkest moment before dawn is not easy, but I believe there are number of signs that the turnaround is finally near. The number of mergers, acquisi-tions, and bankruptcies of companies is on the increase and will soon result in fewer but stronger companies that will once again turn to the business of exploration. An even more interesting development is the notable emergence of very large pockets of private equity targeted for investment into the mineral resource space. Managers and investors of these funds believe in the long-term potential for strong commodity markets but are finding it difficult to identify good investment opportunities as there are very few new, high-quality discover-ies and development costs and timelines remain challenging in many parts of the world. As a professional society, we need to help our members be prepared for the inevitable return of a robust demand for exploration.

To this end, I would like to encour-age all members of SEG to seek oppor-tunities to give back to our profession by making individual or corporate donations to the SEGF or by making time to participate in the many SEG activities that benefit other members and to share your exploration experi-ence. Your participation will serve to get us through to the dawn of the next exploration boom. 1

Once again, the Society turned a pro-jected operating deficit into a gain. By keeping revenues on track and con-straining expenditures, the projected loss was replaced with an operating gain of $163,512. Actual overall rev-enues were quite close to the budget, with the operating gain largely due to well-constrained expenses. The larg-est positive factor in the gain was the highly successful Keystone conference, for which revenues were very close to projections and the expenses were sub-stantially below what had been antic-ipated. Net income from investments of $515,751 was higher than budgeted

and net assets experienced a gain of $432,602. Financial assets on December 31, 2014, were $14,071,869, about a 5% increase over the financial assets of $13,357,112 at December 31, 2013.

For the Foundation, total contri-butions of $353,034 exceeded budget by 18%, once again with generous contributions from both companies and individuals. However, this was substantially below the 2013 contri-butions of $518,720, reflecting the difficult time in the industry. Overall, General and Administrative expenses and Programs and Services expenses were quite close to budget at $669,711,

with variances in individual categories tending to be off-setting. Net income from investments of $167,773 was sub-stantially above the budgeted amount of $104,000, and the year ended with a net loss of $219,957, compared to a budgeted loss of $262,800. Total financial assets on December 31, 2014, were $4,556,098, somewhat below those of 2013 ($4,817,093).

Both organizations once again enter a new year in strong financial position and able to continue to maintain and expand programs aimed at increasing our relevance in the field of economic geology, serving members, and sup-porting students. 1

have announced the discovery of signif-icant epithermal gold mineralization, including the 1,500-m-long Pandora vein at Oklila, in their Afar JV project in a geometrically anomalous section of the Afar rift in Djibouti and Ethiopia (www.stratexinternational.com/project/oklila).

This short review provides a brief introduction to the tectonic and geo-logic setting of the western Arabian-Nu-bian Shield, its recent discovery history, and an assessment of the growing min-eral potential of the region, particularly for a relatively newly recognized deposit style: gold-rich submarine porphy-ry-high sulfidation epithermal-VMS sys-tems in northern Ethiopia and Eritrea, somewhat analogous to the giant gold-rich VMS Hassai camp in Sudan.

Total resources of gold, including past production and various categories of reserves and resources, are difficult to estimate accurately for some deposits due to changes of ownership, constant changes due to varying economic con-ditions, and lack of full resource-related information in available global data sets. Therefore, the figures presented here should be regarded as current best estimates based on data provided on company websites and press releases. For multicommodity VMS deposits, an approximate gold equivalent in Moz Au has been estimated using relative metal prices in US dollars. Due to the uncertainties inherent in metal recovery and payability, any such equivalence estimates are only intended as indica-tive. Relative metal values in determin-ing gold equivalence were based upon US$1,400/oz, copper US$6,300/t, zinc US$2,200/t, and Ag US$18/oz to give a conservative estimate of gold equiv-alence. Despite the uncertainties, gold equivalence allows for a high-level com-parison to be made to total resources of orogenic gold deposits in the same region.

WESTERN ARABIAN- NUBIAN SHIELD— TECTONIC SETTINGThe Arabian-Nubian Shield represents a number of accreted Neoproterozoic greenstone terranes that define the suture between West and East Gond-wana (Figure 1). They are generally an NE-trending collage largely of back arcs

and arcs comprising predominantly greenschist-facies mafic to felsic vol-canic rocks (basalt, andesite, dacite, and rhyolite) segmented by deformed ophiolite complexes of mafic and ultramafic rocks (e.g., Johnson and Woldehaimanot, 2003; Blasband, 2006). They are essentially Neoproterozoic (ca. 800–700 Ma), slightly more deformed equivalents of the gold-rich Archean (ca. 2.7 Ga) greenstone belts, such as the Abitibi Belt of Canada and the Eastern Goldfields of Western Australia, or the Paleoproterozoic (ca. 2.0 Ga) greenstone belts of West Africa.

As such, the greenstone belts of the Arabian-Nubian Shield should be highly prospective for orogenic gold deposits. The primitive oceanic crust of the greenstone belts (e.g., Johnson and Woldehaimanot, 2003) of northern Ethi-opia, Eritrea, Sudan, and possibly Egypt (Figure 2) should also be particularly prospective for gold-rich VMS deposits, given that the primitive greenstone

belts are similar to those of the giant VMS provinces of the Abitibi (Noranda, Horne, Bousquet-LaRonde) and Flin Flon belts of Canada. The shield becomes contiguous with the Mozambique Belt or East African Orogen to the south where crustally reworked high-strain and high metamorphic grade terranes are far less favorable as gold provinces.

DISCOVERY HISTORY OF OROGENIC GOLD DEPOSITSIn terms of primary orogenic gold resources, the western Arabian-Nu-bian Shield has recorded a remarkable growth rate in recent years (Figure 3). From a known endowment of less than 0.6 Moz nonalluvial gold indicated from ancient mining, approximately 3 Moz gold was then discovered in the 1990s, and thereafter almost 25 Moz gold from about 2000 to 2014. The path to discovery has witnessed key milestones. First, numerous orogenic gold prospects

have been investigated in the western Arabian-Nubian Shield for decades (for exam-ple, Dul Mountain in western Ethiopia, recognized by the Ethiopian Institute of Geolog-ical Survey in the 1980s and explored in the early to mid-1990s), but the first >1-Moz gold resource (final total resource >3 Moz) recorded was Lega Dembi (Midroc Gold; e.g., Billay et al., 1997) in the Adola Belt of Ethiopia (Figure 2) in 1997, following privatiza-tion of the deposit, which had been mined on a small scale since the late 1980s.

discovery dates are uncertain given that many of the deposits were clearly historical gold prospects, some dating back several centuries. Here, the year of recognition of clear potential for a 1-Moz or greater gold resource is used as the discovery year. Next was the recognition of a significant resource at Sukari in Egypt (e.g., Helmy et al., 2004), the site of ancient mining, in 1998, with Centamin being granted an exploitation licence in 2005 and gold production commencing in 2009. The Sukari deposit now has a total resource of about 17.7 Moz gold. Koka, in Eritrea (e.g., Carville et al., 2010), was explored beginning in 1998, but the first significant resource was only announced by Chalice Gold in 2005. Now owned by China SFECO, the total resource is approximately 0.92 Moz gold. More recently, in 2013 KEFI Minerals announced a total resource of 2.05 Moz gold from its Tulu-Kapi orogenic gold deposit in western Ethio-pia, and Aurigen Resources is currently assessing promising orogenic gold mineralization at Assosa in the same region. Orca Gold started exploration in northern Sudan in 2011/12 and announced a 1.7-Moz gold resource from its Galat Sufar South orogenic gold deposit in 2013. Midroc in 2014 considered that it had a resource of about 1.3 Moz gold from its Jilaye project, but it is unclear from geologic descriptions if this mineralization is orogenic gold or a gold-rich skarn.

DISCOVERY HISTORY OF GOLD-RICH VMS DEPOSITSThe VMS discovery trajectory of the western Nubian Shield has also accel-erated. While small traditional VMS prospects, comprising Cu-Zn-Ag-Au mineralization, have long been known from the Western Arabian-Nubian Shield, recent discoveries indicate far greater VMS endowment, particularly of gold-enriched deposits. Such deposits are recognized here as having greater than 15% gold by relative metal value in calculated total gold equivalent gold resources. Since 1992, there had been a number of small gold-rich VMS deposits known in the Hassai camp in Sudan (e.g., Amireault, 2006), with an expan-sion to 12 open pits by 1994. However, it was not until about 2010 that the potential for gold- and copper-rich deposits at depth was fully realized. Subsequent exploration by La Mancha has realized a resource of about 6.3 Moz gold and 1.3 Mt copper, for which it reports a 12.1-Moz gold equivalent total resource in the Hassai camp, equivalent to our estimate of 12.15 Moz gold equiv-alent (52% gold by relative metal value).

Similarly, VMS deposits were known for many years in Eritrea at prospects such as the large but low-grade Emba Derho deposit. However, this Cu-Zn-Ag-Au deposit, owned by Sunridge Gold Corp, contains only approximately 8% gold by relative metal value within its 6.3-Moz gold equivalent resource

(from Sunridge Gold Corp website), so, although significant, is not included here in our gold-rich VMS category. It was the discovery of Bisha (e.g., Barrie et al., 2007) by Nevsun in 2002/3—leading to mine start-up in 2008 and first gold production in 2010—that led to renewed interest in VMS explo-ration, particularly since the near-sur-face oxide ore was very gold rich. The total resource is quoted at 1.2 Moz Au, 14 Moz Ag, 0.43 Mt Cu, and 0.77 Mt Zn, for an approximately 4.6 Moz gold equivalent, with about 20% gold by rela-tive metal value in this resource. Sun-ridge Gold Corp’s other VMS deposits at Adi Nefas (0.72 Moz gold equivalent) and Debarwa (0.67 Moz gold equivalent) are also gold-rich VMS deposits, both with about 27% gold by relative metal value in the calculated gold-equivalent resource. Renewed exploration activity at this time in Tigray province, north-ern Ethiopia, led to announcement of a total resource of 0.25 Moz Au, 3.39 Moz Ag, 75,232 t Cu, and 92,682 t Zn (0.8 Moz gold equivalent) for the Terakimti VMS deposit by Tigray Resources (now East Africa Metals) in 2013. This deposit is similarly gold rich (32% of gold by relative metal value), with high gold grades in the oxide ore, and has smaller satellite VMS deposits.

This rapid increase in total known gold-equivalent resources of VMS depos-its to almost 20 Moz has led to renewed exploration activity by companies such as East Africa Metals in northern Ethiopia in the past two years. Although no resources have yet been released as exploration is ongoing, a new belt of gold-rich porphyry-related high sul-fidation epithermal-VMS deposits is appearing with similarities to the newly recognized restricted group of gold-rich VMS systems described by Dubé et al. (2014). These authors include in this group the Archean deposits at Horne and Bousquet-Doyon-LaRonde in the Abitibi Belt of Canada, the Paleozoic deposit at Mt. Morgan in Australia, the Mesozoic Eskay Creek deposit in Canada and, importantly, the Neoproterozoic deposits of the Hassai camp in Sudan within the western Arabian-Nubian Shield, as discussed above. Recently pub-lished, peak diamond-drill gold results by East Africa Metals from an approxi-mately 5 km long mineralized trend in the Mato Bula district include 28.2 m at 8.5 g/t Au and 0.24% Cu for Mato

FIGURE 3. Plot of year of discovery or first resource vs. current size in Moz gold or Moz gold equivalent of primary orogenic gold and gold-rich VMS deposits.



Bula in the west, 12 m at 17.34% Au for Da Tambuk in the east, and 22.9 m at 14.34 g/t Au in between. The long trend of foliated sericite-chlorite-silica alter-ation and highly variable Au-Ag-Cu-Zn ratios, with accessory Mo and Ba, within plunging mineralized lenses point to potential definition of a new gold-rich porphyry-related high sulfidation epithermal-VMS camp. Its similarities to Bousquet-Doyon-LaRonde in several geologic features indicate that it has the potential to further increase the gold endowment of the region if ongoing exploration continues to be successful.

SIGNIFICANCE TO POTENTIAL GOLD ENDOWMENTThe increase from a known gold-equiv-alent endowment in primary deposits of less than 3 Moz from 3000 BC to the 1990s to over 40 Moz from about 2005 is incredibly rapid, particularly at a time when major gold discoveries appear to be proving elusive elsewhere in the world (Richard Schodde, pers. comm., 2014).

The question can be asked about the future potential for endowment growth, given the renewed exploration effort that success in this segment of the Nubian Shield is now generating. One way of estimating this is to plot the known discoveries in order of size on a cascade diagram as shown in Figure 4. Given the similarity to older green-stone belts, it is possible that Sukari does not represent the largest orogenic gold resource and Hassai will not be the largest gold-rich VMS camp to be dis-covered in the shield, particularly given the size of the terrane, its exploration immaturity, and the variety of coun-tries, cultures, and mining legislation it encompasses. Hence, based on the

cascade diagram in Figure 4, orogenic gold discoveries with >20 Moz gold and/or gold-rich VMS discoveries with >15-Moz gold equivalent resources are possible. However, even if the deposits with the largest footprint have been discovered, as elsewhere in the world, first or very early in the exploration cycle, statistically, there still appear to be a number of undiscovered deposits in the 10- to 3-Moz gold or gold equivalent range.

CONCLUSIONSThe past decade has seen a signifi-cant surge in exploration success and increase in gold endowment in the

western Arabian-Nubian Shield. The region is clearly emerging as having a gold endowment of global significance that will continue to grow. This has been essentially against the global trend of declining gold discovery efficiency over the same period. We interpret two main reasons for this late “blossoming” of the gold endowment of the region. First, past political instability and negative perceptions, warranted or not, of both mining legislation and explora-tion potential in this area compared to other Precambrian greenstone terranes caused a delay in commencement of modern gold exploration activity to test historical gold occurrences in those to page 16 . . .

terranes. This meant the western Arabian Nubian Shield simply lagged behind other emergent jurisdictions by more than a decade, although the shield and its younger components in the Afar Depression are now becoming the exploration destination of choice for several junior and major gold companies. Second, the general lack of high-resolution geophysical databases in this part of Africa has also contributed to the overall exploration immaturity of the prospective greenstone terranes compared to terranes elsewhere, where such databases provided superior understanding of regional geology and district-scale exploration targets.

The future looks to be one of increas-ing gold endowment in coming years. The ultimate gold endowment of the terranes depends on whether the largest orogenic gold and gold-rich VMS depos-its/camps have been discovered already. Even if they have, there still remains the potential for discovery of multiple world-class deposits. Recent exploration results from northern Ethiopia, in particular, raise the possibility that a newly recog-nized class of gold-rich submarine por-phyry-high sulfidation epithermal-VMS deposits are present within the terrane. Deposits or camps of this type elsewhere, particularly Horne and Bousquet-Doy-on-LaRonde in the Abitibi Belt of Can-ada, have demonstrably large contained gold and gold-equivalent endowments.

The third SGA-SEG-UNESCO-IUGS Short Course on African Metallogeny was co-organized by SGA and the Managem mining group. It was held in Marrakech, Morocco, from September 29 to October 3, 2014. Seventy-four participants from nine countries in Africa and Europe (Morocco, Senegal, Nigeria, Cameroon, Sudan, Democratic Republic of Congo, Guinea, Benin, France) attended the short course, with participation of Moroccan attendees from Managem, OCP, ONHYM, and universities. Unlike the two previous short courses (Ouagadougou 2012 and Kitwe 2013), the Marrakech short course was extended to include min-ing and R&D initiatives in the mining industry. A large portion was also devoted to the management of human resources in the mining industry, as well as social acceptance, particularly based on Managem’s experience in its exploration projects in Africa. One of the main goals of the course was to have a majority of local specialists as presenters. Thirteen of the 21 lectur-ers were Moroccan professionals (not including the leaders of the field trips, who were affiliated with Managem and OCP). All lectures were given in French but were translated simultaneously into English by VIP Events from Marrakech.

The course materials were distributed to participants on a USB key.

This third short course for the first time addressed underground and open-pit mining practices. Thirty participants were present during the mining ses-sions. Interest in these subjects demon-strated a continued demand for this kind of meeting from professionals of the mining industry engaged in African projects. Additionally, hot topics related to exploration and mining opportu-nities in Africa (local mining laws, industrialization links with mining operations, training of local profes-sionals, political stability, inter-African economic exchanges and development, social acceptance) were debated during this short course, giving a complete picture of the mining industry.

The field trip at the beginning of the short course (day 2) was much appreci-ated by the participants. An interesting presentation of underground mining techniques was undertaken by Mana-gem at its Draa Sfar mine, facilitating interaction between the presenters and the participants. A geological cross section of the Draa Sfar VMS deposit was also organized by Managem at the –1,100-m level of the mine, which was the first underground experience for some of the participants. The group also

visited the industrial complex of Gue-massa, with its R&D unit, geometallurgy plant and hydrometallurgy facilities, and analytical laboratories.

The success of such a short course depends not only on the course coordi-nator, but also on good cooperation and efficiency from local partners. This has been fully the case with the Managem group, represented in Marrakech by Dr. Lhou Maacha, General Director of Exploration and Development, along with Mrs. Aicha Quechai, Assistant-Di-rector. The participation of the Office National de Hydrocarbures et des Mines, Geological Survey of Morocco (ONHYM), Office Chérifien des Phosphates (OCP), Faculté des Sciences-University of Oujda, and Faculté des Sciences et Techniques of Marrakech (FST) was also appreciated. We also acknowledge Mrs. Véronique Ernest (GeoRessources) for her efficiency during the circulars preparation and four graduate students of the FST Marrakech (Mrs. Amal El Arbaoui, Mr. Abdelmalek Ismaili Alaoui, Saa Lolo Koundouno, Fortune Tulomba Niemba) for logistical help during the course. The sponsorship of IUGS, SEG, ONHYM (presenters), and OCP (phosphate field trip organization) has been very much appreciated and we hope to continue to have their support going forward. 1

The 9th Ore Deposit Models and Exploration Workshop was held in Shanghang, a mining town in Fujian Province, China, from November 9 to 16, 2014. The workshop was sponsored by the Zijin Mining Group Company, the largest gold mining company in China, and co-sponsored by the Geological Society of Fujian, China, Fuzhou University, the Society of Economic Geologists (SEG), the Society for Geology Applied to Min-eral Deposits (SGA), and the Depart-ment of Earth Sciences, University of Toronto. The organizing committee for the workshop was led by Steve Scott and Kaihui Yang.

Distinguished from previous years, the workshop included the usual five days of lectures and labs, followed this year by a two-day geologic and cultural field trip. The lectures were held at the headquarters of Zijin Mining Group, and the daily schedule included lectures, laboratory sessions, and discussions. The instructors of this workshop were Steven Scott, University of Toronto, Canada; Noel White (SEG 1993 F), Hefei University of Technology, China; Richard Gold-farb (SEG 1989 F), U.S. Geological Sur-vey in Denver, Colorado, USA; David Cooke (SEG 1992 F), University of Tasmania in Hobart, Australia; David

Leach (SEG 1979 SF), recently retired from the U.S. Geological Survey and presently a consultant in the minerals industry; Zhaoshan Chang (SEG 2004 F), James Cooke University, Towns-ville, Australia; Chusi Li (SEG 1997 F), Indiana State University in Bloom-ington, USA; Kaihui Yang (SEG 2002 F), Zijin Mining Group Company Limited, China; and Huayong Chen (SEG 2009 F), Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, China. Joan Scott organized the laboratory sessions. Lectures were given in English with translation into Chinese and all slides were bilingual.

The workshop covered a wide range of ore deposit types and topics, including volcanic-hosted massive sulfides (Steve Scott), Pb-Zn ores in sediments (David Leach), iron ores (Noel White), porphyry and epither-mal deposits (David Cooke), skarns (Zhaoshan Chang), gold deposits (Richard Goldfarb), magmatic Ni-Cu sulfides and laterite Ni deposits (Chusi Li), iron oxide Cu-Au deposits (Huayong Chen), ore deposit models in research and exploration (Noel White), and implications of the work-shop for exploration in China (Kaihui Yang). The workshop featured a daily two-hour lab session with more than 500 samples together with maps/

sections/photos from typical well-known ore districts worldwide. Daily discussions on all the topics covered were held to answer questions from the participants.

Rich Goldfarb made a presenta-tion on behalf of SEG to attract new members. Dave Leach did the same on behalf of SGA. The lectures were followed by a field trip to the Zijin-shan gold-copper mine, organized by Zijin Mining Group. It is the largest gold mine in China, with annual production of 15 to 18 tonnes gold during 2008–2013. The ore deposit is a large high sulfidation epithermal gold-copper system, with resources of 326 tonnes gold and 2 million tonnes copper, and is surrounded by a number of smaller but high-potential porphyry copper-molybdenum and

low sulfidation gold-silver-base metallic systems. It is hosted by a Cretaceous volcanoplu-tonic belt of the Yanshanian magmatic arc along the eastern coast of mainland Asia that is believed to be related to the northwestward subduction of the west Pacific plate. The participants visited the open pit and the core storage for the geology of the deposit, as well as a mine park that is built on the waste dump as part of the environmental protection program. The mine also uses modern technologies such as a large-scale bio-leaching pad.

About 450 students, profes-sors, and field/research geolo-gists from universities, research institutes, and exploration/mining companies participated in the workshop, which has typically attracted 250 to 300, demonstrating a strong interest in China for such a presen-tation. A total of 328 participants attended the workshop in person at the headquarters of the Zijin Mining Group. In addition, some 120 geolo-gists attended the lectures via remote video conferencing systems con-nected to 11 of Zijin’s mines across China. About 140 students came from the Zijin Mining College of Fuzhou University and other universities. With the generous financial support from the Zijin Mining Group, in particular, 16 students of the SEG Student Chapter and two professors

came from University of Toronto for the workshop and the following field trip and cultural visit. They interacted with Chinese students and geologists throughout the lectures, field trip, and social events and directly observed activity at Chinese universities and in the mining industry, which are little known in the West. For most of the Toronto students, it was their first trip to China or Asia and was a period of great cross-cultural experience.

Zijin Mining Group is acknowl-edged for its tremendous logistic and financial support for the workshop,

especially the generous financial aid for the students from both China and Canada. The workshop was initiated by Chen Jinghe, a geologist, founder and the Chairman of Zijin Mining Group.

The workshop will celebrate its tenth year in China from November 10 to 14, 2015, with registration on the 9th at Chang’an University in Xi’an, Shanxi Province. For more information, please contact, in English or Chinese, Professor Jiao Jiangang: E-mail: [email protected], Telephone: +86 13096964973. 1

Students and professors from the University of Toronto who attended the workshop had the opportunity to observe Chinese culture and mining practices up close.

ABSTRACTThis paper presents a case study in the use of applied geometallurgy for initial process design at the Sierra Mojada Ag-Zn project located in western Coa-huila state, Mexico. Sierra Mojada is a highly oxidized carbonate replacement deposit with current global resources of 163 Moz silver and 2.2 B lb zinc. The process metallurgy for silver was devised utilizing SEM-Mineral Libera-tion Analysis characterization. Silver mineral species of primary significance are acanthite and bromargyrite. The results quantified the specific min-eralogy of the silver ore and gangue, elemental deportment, and particle size distribution. The techniques employed are readily available to the exploration manager at reasonable costs, and draw a road map forward for additional design parameters.

INTRODUCTIONThis paper presents the results of applied geometallurgy at the prelim-inary economic assessment (PEA) level for initial process design of the Sierra Mojada Ag-Zn project located 200 km north of Torreon, in western Coahuila state, Mexico (Fig. 1). The project is being developed by Silver Bull Resources, Inc. (TSX: SBL), Vancouver, BC. The district has a long, complex history of early lead mining followed by decades-long efforts to develop the oxidized zinc resource, to the current effort to develop the silver resources with by-product zinc. This paper will focus on the evaluation of the silver mineralogy and deportment.

CURRENT RESOURCESierra Mojada is a deeply oxidized, zoned Ag-Zn (Cu-Pb) carbonate

replacement deposit (CRD) with current NI-43-101 PEA-level resources of 71.2 Mt at an average grade of 71.4 g/t Ag (25 g/t cutoff) and 1.39% Zn. The global resource is 163 Moz of silver and 2.2 B lb of zinc (JDS Engineering, 2013). Con-tained copper and lead are not currently inventoried.

GEOLOGY AND STRUCTURESierra Mojada is hosted in the Coahuila terrane of the Eastern tectonic zone of Mexico, which represents a passive plate margin. Basement rocks consist of weakly metamorphosed andesitic volcanic rocks cut by granite and gra-nodiorite intrusive rocks of Permian to Triassic age. The district is located on Cretaceous platform carbonate rocks of the Aurora formation, part of the Meso-zoic-age Sabinas basin stratigraphy.

The principal structures in the Sierra Mojada district are related to the NW-SE–oriented San Marcos fault zone, which is believed to be a transform

offset linking the Gulf of Mexico to the Pacific Ocean. The San Marcos fault demonstrates four periods of movement from the Jurassic through the Tertiary, followed by N-S–oriented late Tertiary basin-and-range extensional faulting.

ALTERATION AND MINERALIZATIONThe San Marcos fault system has multiple mineralizing intrusions that are inferred from direct and indirect evidence in the district, leading to the identification of the district as a CRD, summarized by Megaw (1996). The district shows a complex history of zoned hypogene sulfide mineraliza-tion followed by oxidation and super-gene alteration of the mineral profile. Hydrothermal alteration follows a clear sequence of dolomitization, carbonate and silica alteration, followed by late carbonate, silica, argillic, and iron oxide alterations related to the oxidation-su-pergene events.

the district mineralization is hosted by dolomite and complex breccia units; the remainder is in limestone. The alteration-mineralizing events have generated two zones of mineralization in the Sierra Mojada district: the Shal-low Silver zone (SSZ) and the Base Metal Manto zone (BMM). Mineralization in the SSZ is dominated by acanthite (Ag2S), and the silver halide solid solu-tion of bromargyrite (AgB)-Iodargyrite (AgI). Subordinate amounts of tennan-tite and chalcopyrite are found deep underground near the historic Veta Rica mine, the thermal center of the district. Silver occurs in early to late high-grade structures, karst and low-angle fault breccias, mantos, and as disseminated replacements in porous, hydrothermally altered dolomite rocks.

SSZ mineralization occurs strati-graphically above and within rocks of the BMM mineralization and is divided into three areas for evaluation: the Fron-teriza (west), Centenario (central), and Eastern zones (east), which are mor-phologically different but geologically connected zones of mineralization. SSZ mineralization stretches for 5 km along strike, up to 400 m width, and up to 200 m in thickness.

The BMM mineralization is derived from a semimassive to massive pyrite-ar-gentiferous galena-sphalerite hypogene manto protolith. The lead mineraliza-tion, largely mined out, consisted of a manto approx. 4 km long, 100 m wide, and 5 m thick. Zinc manto mineral-ization, located immediately under-neath the lead manto, is dominated by hemimorphite (Zn4Si2O7(OH)2-H2O) and smithsonite (ZnCO3). Mineralization primarily occurs as replacement of karst breccia and chimneys in accessory faults that feed the breccia zones. Oxidative and supergene processes, while clearly affecting the BMM, have had little effect on the SSZ mineralization.

PETROGRAPHYBasic petrography and microprobe anal-ysis was incorporated into exploration at Sierra Mojada beginning with Hye In Ahn (2010), followed by two reports by Pietrzak and Renaud (2011) and Kyle (2012). This analysis documented the qualitative ore/gangue mineralogy and paragenesis of mineralization at Sierra Mojada and defined the deposit as carbonate replacement (CRD) as opposed to the Mississippi Valley-type that previous operators theorized. The

revised exploration model guided the underground core drilling programs of 2012–2013 that doubled the size of the Sierra Mojada deposit. However, for mineral process design purposes, quantitative measurements of ore and gangue mineralogy were needed.

GEOMETALLURGYIn late 2012, Silver Bull Resources undertook a geometallurgical evaluation of the Sierra Mojada project, beginning with the silver mineralization. Three representative samples were taken, one each from the Fronteriza, Centenario, and Eastern areas. The samples were 5 kg each of –10 mesh material, com-posited from between 3 and 10 drill holes, and considered representative of the silver mineralization at staged grade intervals.

The samples were sent to the Center for Advanced Mineral and Metallurgical Processing (CAMP) program at Montana Tech, Butte, Montana. The scope of work is detailed below.

n Identify the silver-bearing mineral species (sulfides and halides) and estimate the silver content of the minerals;

n Identify silver mineral particle grain-size distributions and liberation characteristics;

n Determine deleterious metal-bearing minerals (i.e., As, Cu, Pb, and Zn minerals);

n Identify oxide and clay minerals and possible interference characteristics;

n Identify potential refractory char-acteristics that would interfere with cyanide leaching (i.e., copper, encap-sulation [locking], jarosite, etc.).

The ore samples were split to a 1 kg sample size, ground in a laboratory rod mill, wet-sieved, then dried at approx-imately 70°C. Sieve fractions were obtained of +100 mesh (+150 µm), 100 × 400 mesh (38–150 µm), and –400 mesh (–38 µm). Modal mineralogy was determined by using Min-eral Liberation Analysis (MLA) XBSE on the three sieve fractions from the original samples. The MLA results from each sieve fraction were propor-tionally combined, based on the mass distribution from the mechanical sieve analysis. The 100 × 400 mesh sieve fraction was

separated by heavy liquid separation (HLS) using tetrabromoethane (TBE) (ρ = 2.97 g/ml) into “float” and “sink” subfractions. Approx. 30 g of material was used for each HLS. Material from the dense particle “sink” fraction was mounted in epoxy resin, cured, ground/polished, and carbon coated for SEM-MLA analysis.

DEPORTMENTThe deportment of silver minerals is shown in Table 1. Silver is evenly distributed in the Centenario and Fronteriza zones with bromargyrite being slightly more abundant in the Eastern zone. Only trace chlorargyrite and iodargyrite were observed in the samples. Bromargyrite accounts for nearly 80% of the silver and acanthite about 20% of the total silver, and about 1% is from the lead-iron oxide phase, plumbojarosite, in the SSZ samples.

The Centenario zone is highlighted in as an example of the techniques available for basic geometallurgical research. Figure 2 shows the grain size (left) and particle size (right) distribu-tion in a log format. Acanthite grain size is smaller than bromargyrite, having a P80 of about 90 µm and bromargyrite at about 120 µm.

MINERAL LIBERATION ANALYSISFigure 3 shows the mineral locking (encapsulation) properties of acanthite and bromargyrite. Liberation of the acanthite was greater than bromargyrite in the 100× 400 mesh (38–150 µm) sieve fraction. The liberation for brom-argyrite was consistently low although its grain size distribution mimicked the particle size distribution. Typically, the liberation would be much greater when the mineral grain size is similar to the particle size, and this remains unexplained.

Examination of the dense mineral fraction after preconcentration revealed that acanthite grains were relatively numerous compared bromargyrite, but the grain size of bromargyrite was generally larger than acanthite, as shown in Figure 4. Acanthite is typically associated with malachite and cerus-site whereas bromargyrite is typically associated with strontianite, barite, and quartz. The mineral distribution P80 grain size for acanthite was 90 µm in the Centenario, 135 µm in the Fron-teriza, and only 60 µm in the Eastern

zone. Bromargyrite grains size P80 were 120 µm in the Centenario, 135 µm in the Fronteriza, and 140 µm in the Eastern zone. Figure 5a shows locked acanthite particles and Figure 5b shows a liberated acanthite grain. Note the scale of the liberated grain in Figure 5b.

METALLURGICAL DESIGNThe Sierra Mojada project will use a sin-gle flow sheet process facility for treat-ing the ore. The ores require a crushing and grinding circuit to produce a

particle size P80 of 53 µm to max-imize silver recovery, currently at 75%, and project economics. Note where 53 µm falls on the mineral grains size distribution in Figure 2. A cyanide leach and Counter Current Decantation (CCD) circuit will be utilized with the pregnant leach solutions reporting to a Mer-rill Crowe silver recovery plant.

Once the silver has been recov-ered, cyanide recovery as well as zinc recovery will take place in a SART facility. The operation is planned at 8,500 t/d, producing 5.5 Moz/year of Ag over a 19-year mine life.

RECOMMENDATIONS AND CONCLUSIONSThe geometallurgical analysis of silver generated four recommen-dations for the Sierra Mojada project:

n The Sierra Mojada project needs to be geometallurgically domained based on acanthite vs. silver halide mineralogy that will require a substantial num-ber of samples from the deposit. One drawback to the existing program was that the samples submitted to CAMP were com-posites that tend to merge the variability in mineralogy within an orebody.

n The interaction between silver sulfide/halide and zinc oxide mineralogy needs to be docu-mented to a higher measure and incorporated into the domain process. Furthermore, Sierra Mojada needs to be examined as a zinc project with by-product

silver in light of the current market.n Investigations should explore a

reduction in grind size down to –38 m (–400 mesh) to enhance silver recov-ery and increase exposure of locked grains to cyanide leaching.

n Finally, a graphical relationship needs to be established to determine optimum particle exposure to cyanide to maximize recovery, accounting for other factors such as retention time and kinetics.

A solid foundation of geometal-lurgical characteristics of ore is now a

firm requirement for mining projects to move forward from the PEA level. These characteristics feed information not only for plant design but for waste rock and tailings characterization, and eliminate the blind testing methods historically employed in the industry.

Shareholders are now requiring the latest technology to safeguard the environment as well as their invest-ments. That means achieving major reductions in total project risk, mine-mill optimization throughout mine life, and increased levels of operational

predictability. This study cost less than US$5,000 total, and took two months to complete. It will provide a basis for the geometallurgical domaining task that that should involve about 100 samples employing automated Qemscan® at a cost of about US$15,000.

Descripti onThe Carlin-type gold deposits in northeast-ern Nevada, USA, comprise one of the most producti ve gold districts in the world, with gold producti on now ~135 Moz. Mining and research since initi al deposit discovery in the 1960s have generated detailed descripti ons of deposit geology, including recogniti on of features that are common to deposits across northern Nevada. Studies over the past 20 years have determined the age of formati on of the Nevada district, leading to an under-standing of tectonic setti ng and related structural development and magmati c and hydrothermal acti vity coincident with deposit formati on. In spite of this under-standing, no similarly producti ve trends or districts have been discovered in other parts of the world, and no widely acceptable geneti c model has evolved.

This two-day course will begin with an overview of general characteristi cs that defi ne the type deposits in Nevada and will include a secti on on the “Carlin-type”

deposits in southwestern China. The short course will focus on 1) the geologic evoluti on of northeastern Nevada that produced an ideal geologic architecture for the deposits, 2) geologic processes in the late Eocene that were criti cal to deposit formati on, and 3) explorati on, presented as a systems approach that links processes to targeti ng criteria at all scales. Course presentati ons will include detailed descripti ons of deposit geology, including structure, lithology, ore-stage and late-ore stage mineralogy, and related hydrothermal alterati on minerals and mineral zoning. Samples characteristi c of the deposits will be examined, as will polished secti ons of ore minerals and ore and alter-ati on mineral textures, which defi ne these deposits. Presentati ons and discussions will provide a framework to interpret observa-ti ons in the fi eld, along with implicati ons for explorati on and research. The course will conclude with a discussion of geneti c deposit models, including a model recently published in Nature Geoscience by the presenters who have over 40 years combined experience conducti ng research on and explorati on for Carlin-type gold deposits.

The focus will be on the use of tools to create domains for throughput and/or recovery. A range of (new) tools and methodologies are now available that allow suffi cient density of data to be collected in a ti mely and cost eff ec-ti ve manner to permit domain defi niti on relati vely easily and inexpensively. Once defi ned, domains can be included in geo-metallurgical models of ore deposits where they can be applied to mine planning and opti mizati on.

Aeromagneti c Interpretati on

Date Thursday-Friday October 1-2, 2015


Organizer Kim CookPresenter Kim Cook

Descripti on

Discovery and delineati on of new ore deposits is becoming increasingly diffi cult with opportunity for outcropping min-eralizati on in both mature and emerging terranes decreasing rapidly. The ability to create high quality geological and structural representati ons in areas of limited outcrop using remotely sensed data is paramount for regional target generati on, ground selecti on, and also for more discrete mapping and targeti ng at a prospect scale. Interpreta-ti on of aeromagneti c data to produce solid geology and structural maps is not an exact science, however, a systemati c approach using enhanced processing and imagery that incorporates all existi ng outcrop or other geological inputs can result in a high quality map. This Interpretati on short course intro-duces the parti ci pant to magneti c, gravity, and radiometric theory, with a focus on issues that aff ect the interpretability of the data, such as:

n How the Total Magneti c Field changes with respect to locati on in the world.

n Data processing techniques - what types of fi lters bring out certain aspects of the

data, and how to choose the best fi lters for interpretati on purposes.

n How to determine ‘real’ vs ‘processing issues’. What to look out for and what to accept/not accept from a contactor.

n Basic ore deposit models and how they manifest themselves in geophysical data-sets – using real-life examples.

The short course takes a “hands-on” approach, which at the end of 2 days will see each parti cipant producing at least one detailed solid geology map, targets, and possibly cross secti ons. Parti cipants may bring their own data to interpret.

Descripti onFree and Open Source Soft ware (FOSS), or just Open Source, is an idea that seems like it shouldn’t work yet it drives some of the larg-est organizati ons in the world and is strongly supported by a passionate, well-organized community. Beyond soft ware the ideas be-hind Open Source are contributi ng to a wide spectrum of projects ranging from Wikipedia to Open Source Governance. This course will provide an introducti on to the varied Open Source toolset applicable to the minerals industry via a series of practi cal exercises in Exploratory Data Analysis (EDA). The exercises will be hands-on and parti cipants are encouraged to bring their own dataset to work with or use freely available data that will be distributed as part of the course.

On February 19 and 20, 2015, the first training workshop of the Aristotle University of Thessaloniki (AUTh) SEG Student Chapter took place in collabo-ration with the mining company Hellas Gold S.A. The first day was devoted to the core logging of exploratory wells. Sixteen members of the chapter partic-ipated with the support of Hellas Gold S.A. The program included a visit to the exploration department of Hellas Gold S.A. in the area of Madem Lakos mine, where the participants learned about the existing projects in NE Chalkidiki and potential future mining targets. This was followed by a description of the core logging projects from Fisoka, Skouries, and Olympias deposits, and a practical session was held with the assis-tance of geologists Grigoris Thermos, Theodoros Veligrakis, Nikos Nestorov, and Pavlos Tsitsanis, sparking many questions and a constructive dialogue. The first day of the workshop ended with a bus tour of the infrastructures of Madem Lakos mine.

The second part of the workshop was held at the Department of Mineralo-gy-Petrology-Economic Geology, School of Geology at the Aristotle University of Thessaloniki, with more than 25 participants, all members of the local SEG Student Chapter. The presentation was about the use of 3-D design and

modeling of a mine during the explora-tion and exploitation stages. Geologist Lazaros Dalampiras of Hellas Gold S.A. was the main lecturer and presented on the use and the capabilities of the Datamine Studio 3 computer program, discussing his experience at the Mavres Petres mine in Chalkidiki.

The organizing committee and the members of the Student Chapter would like to thank Thomas Sant, Exploration Manager of Eldorado Gold for Greece, Steven Hunns, District Exploration Manager of Hellas Gold S.A., and Scott Randall, Exploration Geologist of Hellas Gold S.A., for their kind contributions. We look forward to the next workshop.

In the last couple of months, several macro-scale events have dramatically affected Alaska’s mining industry and underscored the critical links between Alaska and the global economy. First came the bad news for newly elec-ted Alaska Governor Bill Walker: the plunge in world oil prices left Alaska’s coming-year budget projections about $3.5 billion in the red. The ripple effect of this was a slashing of every budget in every department. One of the things that was cut—temporarily, we hope—was the state’s funding of the Ambler Mining District Road. Deposits like Bornite, Arctic, and Sun, among others, are adversely affected by this decision because the sulfide concentrates that would be produced by mines at these deposits will require an access road to get them to market. Another budget cut that affects the mining industry is the proposed 18% cut in the budget for the State Division of Geological and Geophysical Surveys. Among other things, this cut will eliminate jobs and the state’s long-running and highly regarded airborne geophysical program. Then, just after the new year began, the Swiss National Bank cut its long-s-tanding tie to the euro, sending Swiss francs skyrocking and euros into further troubled waters. The result was a stabili-zation of gold prices as investors looked for a safe haven for their funds. In Alaska, the Fort Knox, Pogo, Kensington, and Greens Creek mines all bene-fitted from this stability. Silver followed gold’s upward move as well, putting smiles on faces at Greens Creek. Lead and zinc, both significant contributors to Alaska’s economy and the bottom lines at Red Dog and Greens Creek, did not share the upward ride of precious metals, with zinc trading in the middle of its 1-year range and lead near the

bottom of its 1-year range. And while copper is not currently a big revenue source for Alaska’s mines, it has a poten-tial to be so in the future and is a strong driver of Alaskan mineral exploration, so its plight is of interest as well. Unfor-tunately, copper took a tremendous beating in 2014, plummeting from the upper $3.30s per pound in January 2014 to lows in the $2.45 range in early 2015. Finally, the Canadian dollar continued to slide against the US dollar, trading in the C$1.25 range, a drop of some 25% in just two years. For Alaskan explora-tion, this means it takes more Canadian dollars to fund a dollar of exploration in Alaska. Since, during an average year, about 75% of Alaska’s mineral explora-tion is funded by Canadian companies, that is bad news to an industry facing another year of limited exploration bud-gets and lackluster investor sentiment. So there you have it, the good, the bad, and the ugly—welcome to 2015!

SUMMARYExploration discoveries come in all shapes and sizes, and are commonly the outcome of well-planned scientific exploration programs, but sometimes serendipity plays a major role—such as in the recent discovery of a signifi-cant outcropping gold system by ALT Resources Ltd at its Paupong project near Jindabyne in southeastern NSW. A couple of years ago, a Jindabyne school student was researching the early

history of the area and came across an article about a local gold-bearing vein in a copy of an 1898 edition of the Sydney Morning Herald. His father (now the CEO of Alt Resources) initially took out an exploration licence covering an area with a very strong magnetic signature associated with an intrusive complex. A small drilling program was undertaken. A Sydney-based petrolo-gist examined the drill samples, and although they lacked significant min-eralization, minor sulfides present were of interest. Based on advice from the petrologist to explore and map the EL, the area of interest shifted outward from the intrusive complex to cover a new area, revealing a large Ordovician sed-iment-hosted gold-bearing vein/stock-work/breccia system covering an area of 25 km2, located in the southern Lachlan Orogen. To date, eight prospects have been delineated and over 900 rock chip samples have been collected, averaging 0.4 g/t Au (max 14 g/t Au) and 2.6 g/t Ag (max 190 g/t Ag), and the presence of accompanying Cu, As, Pb, Mo, and Bi suggests an IRGS association for the gold mineralization. This occurrence was missed by the old-time prospectors and by previous exploration programs as the gold was too fine to pan, and gold was not assayed for in either of the previous stream sediment surveys of the area in the 1970s. This discovery has been a “shot in the arm” for the NSW exploration sector, as eastern NSW (where outcrop is generally good) has long been regarded as fully explored and any outcropping deposits are assumed to have already been discov-ered. The main lessons in this discovery are not to assume (1) that every mineral occurrence is recorded in the relevant geological survey’s database, and (2) that previous miners and explorers have done a thorough job. Drilling of this exciting discovery will commence soon, as ALT Resources is about to list on the ASX and the company has been awarded a drilling grant of A$200,000 in the inaugural round of co-funded drilling grants by the NSW government.

All the Australian states, the Northern Territory, and New Zealand are aggres-sively competing to attract explorers to

their jurisdictions, and 50/50 co-funded drilling incentive programs are the cur-rent strategy in this regard. NSW and Victoria are the last states to introduce these programs, which are designed to refund some of the drilling costs of those explorers who propose the drill testing of innovative targets in frontier regions through a competitive bidding process.

And lastly, Australia’s newest mine has opened in the Campbell Town district of Tasmania. This is a closely settled farming district with significant historic ties to the early days of the Tasmanian convict colony, so one may ask, how could a company obtain gov-ernment and community approval to build an open-cut bauxite mine in such an intensive agricultural region? The answer is that the soils developed over the bauxite mineralization are of very poor quality and, consequently, the land has poor agricultural value!

MEXICO EXPLORATION TRENDS

Despite the financial crisis of 2008 and continued falling prices of precious metals (from 2014 to 2015, gold and silver fell 10% and 26%, respectively), production companies have maintained their growth and exploration programs at mines and operations. The junior companies are gradually leaving the country, hit by the collapse in metal prices and the reforms that the govern-ment has imposed over the last year. These reforms have increased the cost of production and the maintenance cost of mining claims, leading to the release of mining concessions and eventual depar-ture of companies from the country.

Last year was particularly difficult for the Mexican mining industry, impacted as it was by various events and adverse global economic conditions, in which the prices of major metals fell significantly.

Taking stock of the main indicators, employment fell markedly to 79%. In 2014, only 4,000 net new jobs were created, compared to 18,000 in 2013. In total, there were 332,000 directly employed workers during 2014, with 2 million people employed also consider-ing indirect jobs.

On the international scale, for invest-ment in exploration, Mexico dropped to fourth after Chile, and Peru gained ground, moving from sixth to fifth place.

After 10 years of sustained growth, in 2013 the value of the metal mining industry suffered a setback, from $23 billion dollars in 2013 to $20 billion dollars in 2014, based on INEGI data supplemented with data from non-con-cessionable minerals. Although the mining sector remained a productive branch with more investment made in the country in 2014, mining suffered a decrease of 18% in only two years.

In 2014, according to the Ministry of Economy, about 104 exploration proj-ects were postponed or had to adjust their business plans to begin activity at a financially reasonable time. The main national mining companies said the investment commitments for this year will go to new projects (previously evaluated and approved) and the acqui-sition of machinery and equipment, reducing the budgets for new acquisi-tions and exploration projects.

The outlook is grim and we can only hope for a speedy recovery of the global economy; otherwise, the mining indus-try will suffer a crash, as has happened on other occasions in its history.

NORTHERN EURASIA GENERAL

Kazakhstan amended its mining legis-lation effective from 11 January 2015. The key amendments include state preemption right, which will be limited to the so-called “strategic” deposits and areas. The requirement to obtain the consent from the state for alienation of exploration and mining rights and associated interests has been preserved. The minimum mandatory term for the consideration of applications has been shortened to 20 business days, while the time frame for the consideration of applications covering the state’s preemptive right and the Ministry of Investment and Development (MID) consent remains 70 business days.

The amendments also limit the abil-ity to withdraw or revise already filed

applications requesting the waiver of the state’s preemptive right within three months from the submission date. Nev-ertheless, this new rule does not require sellers to sell subsoil use rights and asso-ciated interests to the state.

The government is authorized to approve lists of strategic deposits and areas. Previously, the government used its discretionary powers to des-ignate deposits and areas as strategic and include them on a list. Under the amendments, such a list must further be compiled based on “strategic” criteria which, in turn, must also be developed by the government.

The amendments have lifted the ban on disposing of exploration and mining rights within two years of their being granted. Prior to the amendments, the law provided that the MID could unilat-erally terminate a subsoil use contract if a subsoil user fails to cure more than two previously committed breaches of the obligations under a subsoil use contract or project documents within the time period specified in the MID’s breach notification. Pursuant to the amend-ments, breaching obligations stipulated only by project documents is no longer a sufficient ground for the MID to termi-nate a subsoil use contract. At the same time, the amendments introduced a new, additional ground for the MID to unilat-erally terminate a subsoil use contract: breaching financial obligations under a subsoil use contract by more than 70% for two consecutive years.

The time limits for fixing the breaches, previously determined by the MID at its discretion on a case-by-case basis, are now considered in the law as follows: physical obligations—up to six months; financial obligations—up to three months; and other contractual obligations—up to one month. MID must establish a specific cure period within these time limits. At the same time, in certain cases, a cure period exceeding the established time limits may be extended upon a subsoil user’s request.

The amendments have also extended the maximum time for the development and approval of project documents as follows: (1) from six to eight months for prospecting; (2) from five to eight months for appraisal; and (3) from 18 to 21 months for commercial devel-opment. In addition, all these periods can be further extended for up to an additional six months if the project documents were not developed and approved in time due to circumstances beyond to page 40 . . .

the subsoil user’s control. Feasibility studies are no longer considered as project documents and, hence, as a prerequisite for entering into mining contracts.

The amendments abolish certain mandatory expert reviews of draft contracts. From now on, draft mining contracts will be subject to economic and legal expert reviews, while draft contracts of other types will be subject only to legal expert review. The envi-ronmental expert review has been abol-ished entirely.

Industrial safety, sanitation, and epi-demiological expert reviews of certain project documents at the exploration stage have been abolished. In partic-ular, prospecting project documents and appraisal project documents that do not include test mining are subject only to environmental expert review. Thus, appraisal project documents that do include test mining are still subject to all types of expert review: environ-mental, industrial safety, sanitation, and epidemiological.

As an alternative to the existing ten-dering process, the MID may now grant exploration and mining rights through conducting English-type auctions based on signing bonus bids. The government is planning to introduce a “first come, first served” principle for greenfield applications to be processed within 25 days. The individual licenses will be lim-ited to 2 km2, but application for several licenses will be allowed. The holder will have to pay $2,000 per license per year, with exploration expenditure of $10,000 per year. The amendments substantially change the ownership nature and legal regime of technogenic mineral formations (TMF; tailings, min-eral wastes, metallurgical byproducts, etc.). In particular, TMF will be consid-ered as privately owned if (1) they are formed as a result of the processing of ore imported to Kazakhstan, or (2) they were dumped after 30 May 1992, pro-vided that the mineral extraction tax and/or royalty levied on minerals con-tained therein was paid. All other types of TMF are considered to be owned by the state. The rights for extraction of minerals from state-owned TMF will be granted through direct negotiations with the MID. Operations with private TMF are no longer subsoil use opera-tions. Hence, the use and processing of such TMF will only be regulated by the

civil law and the extraction of minerals in that regard will not be subject to the mineral extraction tax.

COMPANIESThe governor of Chukotka, Development Fund for Far East and Baikal regions, GDK Baimskaya, and ZAO Bazovye Metally signed an agreement of intent on potential development of the Baimka ore zone. The plan envisages develop-ment of the Kekura Au-Ag deposit (2.89 Moz Au grading 8.69 g/t Au) and con-struction of the Baimka GOK. The total resources of the cluster are 31.7 Mt Cu and about 66 Moz Au in porphyry-type deposits. Part of the plan is a power line construction from Magadan to Chukotka estimated at some 38 billion rubles, to be funded by the government.

Polymetal and EBRD signed a credit agreement on a revolving line for $80 million to finance the develop-ment of the Kyzyl gold project in east Kazakhstan.

Almalyk GMK has completed a $30.6 million construction of the mine at the Kairagach gold deposit. The mine will extract 80 kt of ore per annum.

After being fired by President Truman, General MacArthur was heard to say, “Old mining districts never die, they just need more drilling.” To give a few examples, the Brooks project is mov-ing forward at Lone Tree, additional gold-bearing veins have been discov-ered at Midas, a new deposit has been opened at Jarritt Canyon, and the megapit at Twin Creeks continues to be expanded. Recent drilling at the Pinion deposit has also expanded its size.

The deck chairs continue to be reshuffled on the good ship Mining R Us—Coeur Mining purchased the Wharf mine, Silver Standard now owns Marigold, and Antofagasta acquired Duluth Metals, to name a few.

There are now 22 geothermal plants operating in Nevada that produce 2.5

megawatts of electricity, which appar-ently is enough to power 230,000 homes, or six Gameboys. The bad news is that, even there, now that government support has dried up, drilling for addi-tional resources is considerably reduced.

Nevada Copper is the recipient of good news with the passage of the Lyon County Land Bill, which transfers 10,400 acres to the city of Yerington. This allows for the development of the entire Pumpkin Hollow copper deposit. Romarco apparently has completed financing for the Haile gold deposit in South Carolina and is now pushing toward the start of construction.

As somewhat of a surprise, to me at least, Pilot Gold reported initial met-allurgical results for mineralization in the Western Flank zone at Kinsley. The surprise to me is that much of the gold is associated with pyrite.

As those of us that explore in Nevada know, the state has great potential, good working environment and sup-port, etc. Barrick Gold underscores this point in their summary of last year’s highlights. At Goldrush, twin declines are being permitted to gain access to the deposit for better exploration options. Turquoise Ridge is being developed into a “core” mine. With an average grade of 16.5 g/t Au, it has the highest grade of any operating mine in Barrick’s holdings. They are also expanding the resource to the north. The feasibility study at Spring Valley is scheduled to be completed this year, and it has the potential of being developed into a stand-alone mine.

Small to medium gold producers con-tinue to push ahead. Atna is producing from Pinson, and McEwen Mining has an EIS underway to reopen the Gold Bar operations. Solitario is in the process of permitting mining and processing at Mt. Hamilton. Entrée Gold is con-duction drilling to support a prefeasi-bility study for the Ann Mason copper deposit near Yerington.

Finally, I am here to tell you there are some people who just do not love us. One of the Nevada state highways in the Comstock has started to disap-pear into a historic underground mine working. This is a considerable distance from Comstock Mining’s operations in the district. You guessed it—there has been finger-pointing claiming that the new operation is responsible. This leads me to quote a great philosopher: “Deep enough.” 1

PRESENTERS K. Howard Poulsen specializes in structural aspects of exploration. With

more than 40 years experience in research and exploration, Howard has numerous publications in peer-reviewed journals and has consulted for the U.S. Geological Survey, the USSR Institute of Geology and Applied Mineralogy, Shenyang Institute, P.R.C., the BGR (gold deposits in Africa), and UNESCO (the Carpathian arc). His focus is on problems of signifi cance to global mineral exploration. Most recently, Howard has worked for

industry on gold deposits in the Canadian Shield, eastern Africa, Western Australia, and in the North American Cordillera, from Honduras to Alaska.

Harold Gibson went from a successful career in the mining exploration sector to teaching at Laurentian University in 1990, where he is Director of the Mineral Exploration Research Centre (MERC) and Professor of Volcanology and Ore Deposits. His research is fi eld based, spans ancient and modern environments, and focuses on VMS ore systems and submarine volcanic processes and deposits. Current research areas include the Paleoproterozoic Flin Flon and Snow Lake VMS districts,

northern Manitoba and Saskatchewan, the Archean Noranda VMS district and Abitibi greenstone belt of Ontario and Quebec, VMS deposits of the Guerrero terrain, Mexico, the Lau Basin and Tonga/Aeolian arcs, and the South Indian mid-ocean ridge.

DESCRIPTIONGranite-greenstone terranes are remnants of once larger tracts of metavolcanic, metaplutonic, and metasedimentary rocks now surrounded and/or intruded by granitoid rocks of similar absolute age. They are important sources of gold, zinc, copper, nickel, and other commodities. The course will provide an overview of geological principles and tools needed to work effectively in this setting, with examples from Precambrian shields and younger accretionary orogens. The recognition, in outcrop and drill core, of volcanic, sedimentary, and plutonic protoliths that have been altered, metamorphosed, and deformed is a recurring practical problem; the application of basic fi eld criteria along with sup-porting data will be used to establish a framework for mineral exploration. Descriptions of the main types of mineral deposits found in this setting will be augmented by a discussion of exploration guidelines. The two-day course will consist of eight two-hour modules and is aimed at those who plan to work in such terranes, including young professionals and students, as well as managers who possess some geological background.

SEG at GSA 2015Preliminary SEG Program

November 1–4, 2015 Baltimore, Maryland, USASEG Meeting Coordinator, Jeffrey L. Mauk (U.S. Geological Survey)

SEG Pre-Conference Field TripThe Historic Sykesville Ultramafi c Rock-Associated, Fe-Cu-Co-Zn-Ni Mineral District: Tailings and Core

October 31, 2015Leaders:

PHILIP CANDELA, University of Maryland, [email protected] PHILIP PICCOLI, University of Maryland, [email protected] ANN G WYLIE, University of Maryland, [email protected]

Capacity: Minimum 10 / Maximum 20 participants

DescriptionCopper and iron were mined in the Sykesville District between ca. 1750 and the early 20th century. Four abandoned mines plus prospects are situated in a narrow 16 km belt, ~25 km NW of Baltimore. Sulfi de mineralization is hosted by banded quartz-magnetite rock, and to a lesser extent, in the adjacent detrital serpentinite that are part of the deformed and meta-morphosed Liberty Complex of the Maryland Piedmont. Detrital chromite containing high ZnO has been found in all units including the metasedimentary country rock, and quartz-mag-netite rock, suggesting that ultramafi c material was present on the seafl oor during mineralization and sedimentation. Chalco-pyrite, bornite, pyrite, sphalerite, hessite, electrum and various thiospinels, including siegenite, constitute the mineralization, which was likely precipitated by seafl oor hot-springs during the early Paleozoic. The Mineral Hill Mine was drilled as a cobalt prospect ca. 1979; portions of the core will be available for viewing. At Mineral Hill, samples of the quartz-magnetite rock and the blackwall zones (actinolite, talc, chlorite, some sulfi de-bearing) can be found among the tailings.

SEG Post-Conference Field TripPlacer Deposits of the Atlantic Coastal Plain: Stratigraphy, Sedimentology, Mineral Resources, Mining and Reclamation

November 5–6, 2015Leaders:

RICK BERQUIST, Virginia Department of Mines, Minerals, and Energy, [email protected] KARST, Iluka Resources Ltd., [email protected] ANJANA SHAH, U.S. Geological Survey, [email protected]

Capacity: Minimum 12 / Maximum 20 participants

DescriptionPlacer deposits are unique in terms of the relative ease with which excavation, processing and remediation occur. They can encompass large areas and tonnages, and frequently supply multiple products. Placer deposits containing ilmenite, rutile, zircon as well as minor amounts of other minerals are abundant in the Atlantic Coastal Plain of the southeastern and mid-Atlantic U.S.

Participants in this fi eld trip will observe heavy mineral deposits in a variety of settings in Maryland and Virginia, ranging from Tertiary outcrops of ancient shorelines to modern beaches where deposits are currently being formed. Relations to source rock, processes governing erosion, transport and deposition, and geophysical characteristics will be discussed. The trip will also include a visit to an active placer mining site in Stony Creek, VA. Participants will have the opportunity to examine a deposit of interest, and will also tour a commercial separation facility in order to learn about extraction, process-ing, and reclamation.

DaviD abbott (SEG 1983 F) is the recipient of the 2015 Ben H. Parker Memorial Medal, the oldest and most distinguished award of the American Institute of Professional Geologists (AIPG). The award is presented to individuals who have long records of distinguished and outstanding service to the profession. Abbott is best known for his column, “Professional Ethics & Practices,” which he has written for The Professional Geolo-gist since 1995. Mineral resource and mineral reserve classifica-tion systems and their application to real deposits have been at the heart of much of David’s professional career. In addi-tion to his AIPG activities, David has contributed to a number of other U.S. and international professional organizations.

Daniel GeorGe WooD (SEGF 2009 F) was appointed an Officer of the Order of Australia in the General Division (AO) Austra-lia Day 2015 Honours List. He is cited for distinguished service to the mining and resource industry, particularly mineral exploration, through contributions as a geologist, an aca-demic, and as a mining company executive.

Wild Places: The Adventures of an Exploration Geologist

In this autobiography, Harold Linder (SEG 1974 SF) recounts the highs and lows of a 50-year career in geology, beginning with his undergraduate studies at MIT in the 1950s. Working in the Mojave Desert in California during the 1986 field season, Harold discovered the Castle Mountain gold deposit, thus achieving the dream of every exploration geologist—to discover and follow through to production a major min-eral deposit. Written for the layman, this nicely illustrated book follows Harold as he traverses the globe and will be of interest to anyone wanting to know what exactly it is that a field geologist does.

Available from Amazon.com ($40) and Castle Mountain Books ([email protected]).
