Some knowledge of a countryrsquos history may be valuable when observing and assessing its industrial development especially in a country such as Namibia In South Africa apartheid tore the country apart both politically amp economically but such a revolution fortunately has thus far remained absent in Namibia Instead Namibia is enduring a much smoother transition towards its independence from the West Relatively low wages a less strict environmental regulatory system and the promise of prolonged peace in Namibia have increased the worldwide propensity to invest in unearthing Namibiarsquos vast raw material resources In turn investing companies have improved the infrastructure schooling healthcare and other aspects of the economy as a whole It should be noted that although Namibia is a very large country the country is only lightly populated and most of the population inhabit four major cities Of these the capital Windhoek is largest and most important Located in the Khomas Region with a population of 230000 it is a major trade centre of sheep skins By examining the development of this major city some of the countryrsquos recent history is unveiled The city of Windhoek is traditionally known by two names Ai-Gams from the Nama people and Otjomuise in the language of the Herero people Both traditional names refer to the hot springs The early settlements near Windhoek came to be due to the water flowing from the hot springs in the area In the mid-1800s Captain Jan Jonker Afrikaner settled near one of the main hot springs located in the present-day Klein-Windhoek Wars between the Nama and Herero eventually destroyed this town By 1873 a Rhenish missionary Hugo Hahn was dismayed to see that nothing remained of the towns former prosperity In 1878 Britain annexed Walvis Bay which was incorporated into the Cape of Good Hope in 1884 but was not interested in extending its influence into the interior of Africa A request by merchants from Luumlderitzbucht resulted in the declaration of a German protectorate over German West Africa in 1884 The German colony came into existence with the determination of its borders in 1890 Germany sent a protective corps called the Schutztruppe under Major Curt von Franccedilois Von Franccedilois stationed his garrison at Windhoek which was strategically situated as a buffer between the Nama and Herero while the twelve strong springs provided water for the cultivation of food Present-day Windhoek was founded on 18 October 1890 when Von Franccedilois lay the foundation stone of the fort which is now known as the Alte Feste (Old Fortress) During the next fourteen years Windhoek developed slowly with only the most essential government and private buildings being erected In Klein-Windhoek plots were allocated to settlers who started farming on a small scale with fruit tobacco and dairy cattle After 1907 development accelerated when more people migrated to the city This development was also stimulated by a larger influx of western settlers arriving from Germany and South Africa Businesses were erected on Kaiser Street present Independence Avenue and along the dominant mountain ridge over the city The German colonial era came to an end during World War I when South African troops occupied Windhoek in May 1915 on behalf of Great Britain For the next five years a military government administered South West Africa Development of the city of Windhoek and the nation later to be known as Namibia came to a virtual standstill After World War II Windhoeks development gradually gained momentum as more capital became available to improve the areas economic climate After 1955 large public projects were undertaken such as the building of new schools and hospitals hardening of the citys roads and the building of dams and pipelines to stabilize the water supply With Namibias independence from the South African administration in 1990 the city experienced a wind of change that led to accelerated growth amp development Windhoek became the seat of a first democratically elected government of the Republic of Namibia under the guidance of its Head of State amp President Sam Nujoma

SSeessrriieemm CCaannyyoonn aanndd SSoossssuussvvlleeii Sesriem Canyon At the entry to Sossusvlei is Sesriem Canyon where centuries of erosion have incised a narrow gorge about 1 km in length At the foot of the gorge which plunges down 30 to 40m are pools that become replenished after heavy rainfall You can even have a dip in its murky pools amongst little fish if the water is high enough It was an important source of water for early inhabitants and during the dry season water remains in the upper reaches where deep clefts in the rock reduce evaporation Explorers riders and early travellers used to lower a bucket down to collect the water which normally took 6 lengths of thong tied together hence the name ldquoSesrdquo meaning six and ldquoRiemrdquo meaning thong in Afrikaans The Tsauchab River rising in the Naukluft and Zaris Mountains to the east and flowing through to Sossusvlei formed the canyon Walking through the canyon takes you on a journey back 10-20 million years when sedimentary layers of gravel and sand were deposited and cemented together by lime Pigeons now inhabit the ledges as well as raucous pied crows and chattering starlings But look a little higher and you might see a lanner falcon or the soaring spread of a lappet-faced vulture with a wingspan of 26m At night listen out for the haunting cry of the spotted eagle owl An amazing variety of wildlife has adapted to live in this inhospitable place such as lizards (that only put 2 feet down at a time) and the black toc tokkie beetle that leans forward to allow droplets of morning mist run down its body into its mouth Sossusvlei The sand dunes of Sossusvlei in the Namib Desert are often referred to as the highest dunes in the world Various arguments are laid out to support this claim but all miss the point which is that Sossusvlei is surely one of the most spectacular sights in Namibia Located in the Namib Naukluft park the largest conservation area in Africa and fourth largest in the world - the sand dunes at Sossusvlei are just one excellent reason to visit Namibia The best time to view Sossusvlei is at sunrise the colours are strong and constantly changing The midday heat is intense and best spent in the shade while sunset also offers excellent photo opportunities at Sossusvlei Vlei is Afrikaans for a shallow depression filled with water and the name Sossusvlei should strictly be applied to the pan that lies at the place where the dunes close in preventing the waters of the Tsauchab River from flowing any further - that is on the rare occasions that the river does flow as far as this During exceptionally rainy seasons the Sossusvlei may fill with water causing Namibians to flock there to witness the grand sight but normally it is bone dry This particular vlei is actually a more-or-less circular hard-surfaced depression that is almost entirely surrounded by sharp-edged dunes beyond which lies a formidable sea of rolling sand stretching in unbroken immensity all the way to the coast However the name Sossusvlei nowadays applies to the whole area - an area that encompasses the great plain of the Tsauchab River together with the red dunes that march along like giant sentinels to south and north of the plain

RRoumloumlssssiinngg UUrraanniiuumm MMiinnee Name of Company Roumlssing Uranium (Rio Tinto) Operation Open pit uranium mine (Commenced 1973) Product 3711 tonnes uranium oxide (U3O8) in 2005 Employees 860 (96 Namibian) in 2005 Profit Made no profit in 2005 Introduction Roumlssing is the 6th largest uranium producer of the world and produces over 77 of the world total uranium demand The open pit mine is located in Namibia close to the town of Arandis which is situated 65 kilometres away from the coastal town Swakopmund Although the ore body was already discovered in 1920 it wasnrsquot until the mid 60rsquos that a subsidiary of what is now Rio Tinto showed interest in the ore body and began surveying drilling and evaluating the deposit Roumlssing showed to be an enormous low-grade uranium oxide (U3O8) deposit and in 1973 it was decided to start mining it The operations commenced in 1976 meaning that the mine has been producing for three decades Tour of the facilities The Roumlssing plant has all the necessary processing facilities on site The production of the uranium starts with the blasting of the rock in the mine The open pit is a massive 3 km long 1 km wide and 300 meters deep After blasting the ore is loaded in 180 tonnes trucks which pass through a radiometric scanner Depending on the amount of radioactivity sensed by the scanners the truck is directed towards the crushers the low grade stockpile or the waste dump The ore is crushed and (wet) grinded until it forms slurry The slurry is fed in a combined leaching and oxidation tank where the uranium is oxidized by ferric sulphate into a more soluble form and then leached with sulphuric acid The product of the leaching step is a pulp containing the uranium slime and sand Via cyclones the two are separated and the sand is transported to a tailings dam The RRoumloumlssssiinngg pprroocceessssiinngg ffaacciilliittyy After passing through numerous thickeners the lsquopregnantrsquo solution is brought into contact with beads of resin Here ion exchange takes place whereby the uranium is extracted from the solution Periodically these beads are removed and washed with acid The new solution is more pure and rich in uranium This is brought in contact with an organic solvent to take up the uranium components where in a second stage the solvent with uranium is mixed with an ammonium sulphate solution By the addition of ammonium gas the pH is increased and uranium will deposit as ammonium diurenate Then the solution is again fed in a thickener and a rotating drum filter to produce lsquoyellow cakersquo Finally it is calcined to drive of the ammonia and get the final product U3O8 The Uranium oxide produced is shipped to the USA Canada China and France where it goes to converters for further enrichment After that it is sold to electricity producers in Europe China USA and the Asian-Pacific The majority of the shares are held by Rio Tinto (69) followed by the Iranian government (15) The Namibian government holds only 3 but has the majority in voting rights (51)

LLaannggeerr HHeeiinnrriicchh UUrraanniiuumm MMiinnee Name of Company Langer Heinrich Uranium (A member Paladin Resource Ltd) Operation Open pit excavator-truck uranium mine Product Uranium oxide (U3O8) an estimated 1180 per annum Started 1973 (discovering) March 2007 (official opening) Employees 70 (December 2006) Profit Made no profit during 2006 Development stage Contact persons Katrin Kaumlrner amp Wyatt Buck Introduction The Langer Heinrich Uranium (LHU) mine is located about 80 km East of Swakopmund in the Namib Desert and is the property of Paladin Resource Ltd an Australian company In 1973 a surficial calcrete type deposit was discovered by a government-supported airborne radiometric survey Initially owned by Gencor (a South-African mining company) and later by Acclaim Uranium NL (Australian) both companies were forced to sell due to the downward trend of the uranium price of the time In August 2002 Paladin Resource Ltd became wholly-owner of the LHU mine Recently the price of uranium has nearly twelve folded In January 2004 the pre-feasibility study was completed which confirmed the economic value of the project The mineralization is near-surface between 1 and 30 metres thick between 50 and 1100 metres wide and the deposit extends 15km in length The uranium is mined by means of conventional open pit excavator-truck operation and is proposed to produce 1180t of U3O8 per annum from 15Mtpa raw calcrete materials with a timeframe of 17 year project life The official opening of the Langer Heinrich mine was in March 2007 amp presided over by the president of Namibia Because the LHU mine is just open it is very interesting to see the Development stage (open up ore deposit for production) instead of the Exploitation stage (produce ore on large scale) that you can observe in the Roumlssing uranium mine located about 40 kilometres North-West of Langer Heinrich mine High grade ore Tour of the facilities At Wednesday the 11th of July we arrived at the Langer Heinrich Uranium mine the second uranium mine in Namibia After a health amp safety presentation the geological history amp orebody positioning was presented by Katrin Kaumlrner The uranium mineralization occurs in the form of carnotite [ K2(UO2)2(VO4)23H2O) ] The ore resource study is completed although more boreholes are scheduled to be drilled in the Tertiar sedimentation to increase the measured resources potential The total Mineral resource is 805 Mt of uranium oxide ore at 600ppm of U3O8 containing 47900t U3O8 of which 46 is in the Measured and the Indicated Resource and 54 in the Inferred Resource category at a 250ppm cut-off 1 Mining operation The mining operation will remain to be in the development stage for the coming 20 months The drilling pattern in the LHU mine is rectangular 32 by 35 metres with 115mm hole lengths and ANFO is used as the explosive The drilling operation is 247 while the load- and hauling is done in 9 hours shifts two times a day amp 5 days per week The loading and hauling operation consists of an excavator with 4 Komatsu 100t trucks in operation The ore is divided in four different grades superhigh (900+ppm) high medium and low Each loaded truck is scanned for

radioactivity and directed towards the jaw crusher of the processing plant or one of several specifically graded stockpiles At this time only the super high grade ore is produced in an effort to pay off investments made as soon as possible The pit is backfilled with waste rock material and the whole operation is continued in westward direction 2 Processing plant Before entering the processing area Mr Buck the General Manager gave a presentation detailing the metallurgical processes of the plant In one and a half years time LHU would like to repay all construction costs made approximately US$ 92 million To achieve this estimation only the super high grade ore gt900 ppm is fed in the crushers moreover the increasing Uranium price helps by establishing this goal Furthermore a constant graded feed optimizes the process The 5000t raw ore a day is dropped in the feed-bin with a grizzly on top drops in the jaw crusher with a lt100 mm sized output and afterwards grinded in the wet-scrubbers The gt25mm ore is dropped on a Barren stockpile the gt10mm to emergency stockpile and re-crushed in the cone crusher and sufficient grinded ore a slurry (lt10mm) is fed into the attritioner tanks If the slurry is grinded to a size smaller than 500microm in the attritioner (desliming) screens it is fed to the pre-leaching thickeners to provide a constant feed for the leaching tanks In the leaching tank sodium (bi-) carbonate powder is added to achieve a pH of 9 at 75degC (otherwise the uranium does not dissolve) The heated slime is fed into 6 counter-current decantation thickeners where the slimes move from thickener 1 through all thickener stages The washed slimes exist as underflow thickener 6 to the tailings dam Whereas the barren solution enters at thickener 6 overflows counter-current through all six stages to thickener 1 into the clarifier as a concentrated uranium solution so called pregnant liquor The pregnant liquor is brought into contact with fixed bed ion-exchange resin to extract the uranium from the solution After the resin loading the elution phase takes place it implies the removal of vanadium and uranium from the resin by respectively sodium carbonate and sodium bi-carbonate Subsequently the uranium-rich eluate is precipitated in batched reactor tanks Sulphuric acid is added to lower the pH and hydrogen peroxide is added to let the uranium precipitate The precipitate goes to the settler tank and is then pumped through two stages of centrifuges to remove impurities Finally in the dewatering process the precipitate is dried at 450degC and the final product of 88 pure UO4 the so called lsquoyellow cakersquo is packed into drums weighed and sealed and collected in sea-containers The whole metallurgical process is monitored in the control-room and from the final product is taken a sample for XRF analysis to monitor the quality The containers are transported to Walvis Bay seaport and exported to the consumers of the Langer Heinrich Uranium mine UO4 is produced instead of U2O8 (that produced by Roumlssing) because this has a positive influence on the shipping costs Roumlssing is not yet able to make the production of UO4 profitable which shows that despite the Langer Heinrich Uranium mine is a relative young mining company it has accomplished a lot with a selective well qualified group of mining employees and engineers from all over the world

Name of Company AngloGold Ashanti Operation Open pit mine amp smelting facility Product amp capacity Gold 86200 oz per annum (2006) Employees 313 Profit US$ 23 million Average Gold Price per Kg N$ 131942 Recovered grade 00053 ozt Total cash costs N$ 1794 N$oz Total production costs N$ 2356 N$oz Capital expenditure N$ 33 million Current Ore reserves 5315000 t 108gt

Introduction AngloGold Ashanti is one of the worlds leading gold producers with a varied portfolio of assets and ore body types in key gold-producing regions around the world At the end of 2006 the company had 21 operations located in 10 countries (South Africa Argentina Australia Brazil Ghana the Republic of Guinea Mali Namibia Tanzania and the United States) on four continents together with a substantial project pipeline and a focused global exploration program AngloGold Ashanti produced 56Moz of gold in 2006 of which 26Moz (46) came from deep level hard-rock operations in South Africa and the balance of 3Moz (54) from the shallower and surface operations around the world Greenfields exploration is under way in Western Australia Colombia and the Democratic Republic of Congo (DRC) and through exploration partnerships and joint ventures in Alaska Russia China the Philippines and Laos The first gold-bearing quartz veins discovered in Namibia were found in the Rehoboth district as early as 1899 Although many prospects opened up and were exploited in 1933 and 1934 all were forced to close mainly due to the low and erratic grade of the mineralization The Navachab gold deposit was discovered as a result of a geochemical exploration programme in 1984 (exploration for carbonate-hosted gold deposits) Navachab has been in production since 1989 and is the only gold mine in Namibia AngloGold Ashantirsquos interest in Navachab dates back to 1998 when it bought a 70 stake in the mine In 1999 it increased its stake from 70 to 100 Navachab open pit Tour of the Facilities The Navachab deposit is hosted by Damaran greenschist-amphibolite facies calc-silicates marbles and volcano-clastics The rocks have been intruded by granites pegmatites and (quartz-porphyry dykes) aplite and have also been deformed into a series of alternating dome and basin structures The mineralised zone forms a sheet-like body which plunges at an angle of approximately 20deg to the north-west The mineralisation is predominantly hosted in a sheeted vein set (plusmn60) and a replacement skarn body (plusmn40) The gold is very fine-grained and associated with pyrrhotite and minor trace amounts of pyrite chalcopyrite maldonite and bismuthinite The mine is situated 10km South-West of Karibib and 170km North-West of Windhoek on the Southern West coast of Africa Navachab is an open-pit mine Its processing plant with a


19

production capacity of 110 000tpm includes mills carbon-in-pulp (CIP) and electro-winning facilities Approximately 80 of the gold allows for free milling In 2006 gold production rose by 6 to 86 000oz as increased tonnage throughput offset the effect of a decline in grade from 205gt to 181gt Total cash costs decreased by 17 to $265oz as a result of the increase in gold production as well as the benefits associated with a stronger US dollar in the third and fourth quarters of the year Gross profit adjusted for the effect of unrealised non-hedge derivatives and other commodity contracts more than doubled to $22 million as a result of increases in both production and the price received Capital expenditure remained steady at $5 million and was incurred mainly on preparation for mining of the Grid A satellite orebody and treatment plant optimisation Historical studies on a potential pit expansion which was previously considered uneconomical are being reviewed given the current outlook for the gold price Several brownfields prospects situated within trucking distance are currently under investigation With the lower expected yields total production at Navachab is estimated to decline slightly in 2007 to around 80000oz Total cash costs are forecast to rise to approximately $359oz with capital expenditure anticipated to increase to $5 million (N$33 million) This will be spent mainly on a plant upgrade to accommodate higher tonnes in the future as well as on brownfields exploration Ore reserves and mineral resources are reported in accordance with the minimum standard described by the Australasian Code for Reporting of Exploration Results Mineral Resources and Ore Reserves (the JORC Code 2004 edition) and also conform to the standards set out in the South African Code for the Reporting of Mineral Resources and Mineral Reserves (the SAMREC 2000 Code) Mineral resources are inclusive of the ore reserve component unless otherwise stated AngloGold Ashanti had mineral resources of 1816Moz and ore reserves of 669Moz in December 2006 Of these Navachab accounted for mineral resources of 38Moz and ore reserves of 07Moz

The Etosha National Park is regarded by wildlife aficionados as one of Africarsquos greatest and most intriguing wildlife sanctuaries It was once the biggest national park in the world covering almost 100 000km2 but in 1967 under South African rule the apartheid authorities reduced it in size to its current 22 275km2

as part of a tribal resettlement scheme That is not the only huge number associated with Etosha - the vast dried up white calcrete pan (seasonal lake) was once the biggest lake in the world until climate changes dried up the feeder channels and changed the vegetation from lush jungle to savannah grassland and acacia amp mopane woodland Onersquos first impression of the park is of a vast expanse of dazzling white pans which in the harsh light of midday are painful to look at without sunglasses But in the early morning and late afternoons the pans through tricks of refracted light glow and shimmer as they go through an astonishing range of colour changes from orange through pink and purple to inky deep blue And despite being in a semi-arid area the park is home to over 340 bird 110 reptile and 100 mammal species including close to 3 000 elephant 300 black rhino ndash one of the biggest populations in Africa ndash 27 000 wildebeest 7 000 zebra and rare antelope species like black faced impala Damara dik dik suni amp roan antelope Lion cheetah and leopard are common sights An excellent network of good roads makes Etosha an ideal self-drive destination Ordinary sedan cars will cope well with the roads although in the very short rainy season (irregular between December and April) some tracks become very slippery In good rain years the pans fill with a food-rich soupy water that attracts thousands of wading birds including huge flocks of flamingorsquos turning the strongly alkaline water a deep pink in the mornings and evenings

Name of Company Ongopolo Tsumeb Smelter Operation Smelting facility comprising of three furnaces Product amp capacity Blister copper (985 Cu) 6 000 tons month Employees 210 Profit US$ 23 million (Dec 2006) Introduction Weatherly International acquired the Ongopolo Mining amp Processing Ltd of Namibia in July 2006 Ongopolo is the word for copper in Oshiwambo an indigenous language of Namibia Ongopolo currently operates several copper mines in addition to three concentrating and a smelting facility The company further possesses extensive land holdings in the copper rich areas of the country The Otjihase and Matchless mines are located in central Namibia close to the capital Windhoek whereas the Kombat mine and nearby smelter at Tsumeb are located in the north of the country In addition to these assets a new underground mine is being developed to in time replace the declining Kombat mine This mine located at Asis Far West amp lateral development of the ore body is currently underway Other projects in operation include the Tsumeb West and Tschudi mines To operate continually at maximum capacity the smelter currently imports a lot of ore from Mauritania Zambia and the Republic of Congo Tour of the Facilities The Tsumeb copper smelter comprising three furnaces is a key asset for Weatherly The current operating capacity of the smelter with only one of the furnaces in operation is 2 000 - 3 000 tons per month A second larger copper furnace and the zinc furnace require refurbishment The Tsumeb smelter is currently processing concentrate using feedstock from Weatherlyrsquos own mines at Matchless Tsumeb West amp Otjihase along with throughput from third-party supplies and tolling agreements Weatherly intends to examine the feasibility of expanding Ongopolos

smelting capacity to 50 000 tons per annum by early 2008 Furthermore several projects are underway - The Ausmelt process will be restarted greatly increasing capacity - The smelter is investigating reclamation of its extensive tailingsdam by employing a leaching and electrowinning process and introducing a new electrochemical cell that is very efficient on low grade ore - The smelter is investigating whether it can extract the largest proven Germanium deposit in the world located in its own tailingsdam


24

In the past the Tsumeb smelter was located near one of the richest copper deposits in the world Today this deposit is all but spent yet the smelter remains to be situated strategically All of Ongopolos operations are located along a strategically important and efficient transport route in southwest Africa stretching from the port of Walvis Bay on the Atlantic coast to the major copper producing areas of Zambia and DRC These logistics provide the opportunity to develop Ongopolo into an increasingly significant regional mining and smelting centre serving the nearby mineral resource-rich countries of Botswana Zambia DCR and Angola as well as what remains of production in Namibia The smelter is specializes in the processing of low grade copper ore If the smelter were to process all copper ore itself it may vary well be a profitable undertaking well into the 21th century

Operation Open pit mine amp processing facility Product amp capacity Acid grade fluorspar of 97 purity 130 wmtyear operation Employees 400 Introduction Okorusu is exploiting Namibiarsquos largest fluorite deposit and is the countryrsquos largest fluoride producer The Mine is owned by Okorusu Fluorspar Ltd a subsidiary of the Solvay SA Group The mine is located in the Northern-Central part of Namibia ca 50 kilometres north of the town of Otjiwarongo The old volcano poses an impressive site in the surrounding landscape The mine produces acid grade fluorspar of 97 purity and has all the needed mineral processing facilities on site Furthermore the deposit at the Okorusu is the only carbonatite fluorite deposit that is being mined in the world today A reason for this is that carbonatite fluorite often has a high phosphate content causing a challenge in the production process due to a more complicated separation In the case of Okorusu this problem is overcome by the high to very high grade of the reserves Tour of the facilities There are three pits in production located in the rim of the volcano Ore in the pits consist of marble replacement ores amp carbonatite replacement rocks The current cut-off grade is 20 CaF2 but much of the ore has a grade of up to 50 CaF2 and it reaches a staggering maximum of 95 CaF2 in one of the pits Currently the life of mine is about seven years which is bound to increase considering the minersquos potential There is a possibility of going underground in one of the pits and various new pits are being explored at the moment Production capacity of the mine and process plant is approximately 130 wmt (wet metric tonnes) per year (limited by the processing plant) In order to realize this production level approximately 200 000 tons of rock has to be moved every month The rock is excavated with the drill and blasting method Each blast liberates 25000 tons of material that will be removed from the site within three days The rock strength at Okorusu is exceptionally high around 250 MPa Due to the fact that the deposit dips steeply in some places the stripping ratio rises up to 101 After the ore is removed from the mine is fed to the crushing plant through a grizzly The crushing stage consists of three crushers two jaw crushers and a cone crusher All the machinery in the processing plants of Okorusu is second hand bought from other mines and plants and refurbished and is maintained in house Every morning the whole plant undergoes a visual inspection by the engineers lsquoThe Stress Testrsquo After the crushing stage all material is smaller than 16 mm and is stocked on three different stockpiles depending on the grade and type of the material From the three stockpiles a blend is made which is fed into the milling circuit The stockpiling allows the mills to be fed with a homogeneous blend independent of the ore that is being mined The milling circuit is a wet circuit and consists of a ball mill and a rod mill which operate in parallel Presence of two mills prevents a total production standstill when one of the mills is down for maintenance or because of failure The milling plant operates with a feed of 55 tons per hour and requires 20 m3 of water per hour The output of the milling plant is a pulp that is

classified with a cyclone The overflow (fines) is transported to the flotation plant the underflow goes back to the mill In the flotation plant fluorite is separated from the apatite and other impurities A major capital investment by Solvay has made it possible to increase the recovery of the flotation process with a special chemical After flotation the end product is an acid grade fluorite has to meet the following criteria

bull CaF2 gt 970 bull SiO2 lt 100 bull CaCO3 lt 100 bull P2O5 lt 020

The tailings from the flotation plant contain 3 to 9 Fluor ndash apatite and several rare earth elements It is currently investigated whether these tailings can be processed economically to recover these valuables No amount of effort was spared to in giving us access to both the open pit amp processing facility The hospitality with which we were received was greatly appreciated by all Okorusu Fluorspar for as far as we may assess has a high future potential due to the management proven and indicated reserves but also tailings dam potential

Operation Underground mine amp Processing facility Product amp capacity 250μm Copper sludge 50ktonsmonth Employees 400 Introduction Otjihase mine located about 30 km to the East of Windhoek is one of the 5 mines belonging to the Ongopolo Mining and Processing Limited Weatherly International PLC gained 97 interest in the company in 2006 The ore body at Otjihase stretches 250 m in width is about 5 meters thick and dips to a depth of approximately 1 km It mainly consists of chalcopyrite and pyrite (picture) and the reserves (proven amp probable) are estimated at 11 Mt of 19 copper Because of its allocation and size the ore body is produced by means of room amp pillar mining Currently the mine is investigating a raise in production by backfilling the rooms with cement and allowing for 90 recovery of the pillars In 2006 the life of mine estimate was 5 years Tour of the facilities

I Otjihase Mine The backfilling of former rooms is started at the Karuma chamber at a depth of about 800 m In order to backfill a room a wall is constructed at both sides Subsequently the room is backfilled on both sides of the pillar In order to improve the roofing of the ramps it is strengthened using extra cables and rock bolts Recovery starts with the most center part of the pillar The roof of the created opening is then strengthened with rock bolts after which the remaining parts of the pillar can be recovered All of the recovery is done by blasting Ore is transported by LHDrsquos to an underground primary crusher and subsequently transported by conveyor belts to the surface The mine produces about 50000 tonsmonth Otjihase Orebody

II Tailingsdam amp Tailingsplant All tailings are deposited on the tailingsdam Prior to the re-use of these tailings as backfill in the mining operation it is mixed with cement imported from RSA and Argentina Because the cement represents a relatively large portion of the operating costs the mine is experimenting to reduce the percentage of cement from 3 to 2 by mixing in ash and slack from the Tsumeb smelter Although the process of backfilling requires a lot of water the process has a 70 water recovery Upon taking into account the entire operation the mine water neutral a remarkable achievement in such a dry region as Namibia

III Processing Plant The ore enters the processing plant as with a particle size lt10 mm First the ore is led through a ball mill which grinds it to a fraction of about 250μm Flotation is than used to upgrade the copper content The product is dried and shipped off by train to the Tsumeb smelter where it is converted into blister copper The product contains about 25 copper and the total recovery of the mine is estimated at 93 Because the processing plant at Otjihase can process 110000 tonsmonth and the mine only produces 50000 tonsmonth extra ore from the Matchless Mine is also processed at Otjihase

NNaammddeebb Company Namdeb Operation Open pit and marine mining Product Diamonds 2 million carats per year Started 1994 Profit 336 million N$ Contact persons Paulo Shipoke from Namdeb

Leaonard Apollus from De Beers-Marine Fabian Shaanika fromDe Beers Marine

Introduction On the 17th of July 2007 students and graduates from the department of Geotechnology of the TU-Delft visited the main office of Namdeb in Windhoek Our visit was spread over two days The first day some presentations about the activities of Namdeb were given The second day we were allowed into the sorting room Fortunately a shipment of diamonds had just arrived amp there was a lot to see Namdeb is a joint venture between the government of Namibia and De Beers Marine The company is specialized in finding mining and selling diamonds The diamond market is a thrilling business on which the company motto is based Namdeb is EXCITED which stands for Excellence Care Intelligent solutions Teamwork and Diversity The company constantly evaluates the efficiency of mining and invests in new techniques and exploration to ensure a steady production for the coming 10-25 years One of the results of this philosophy is that since 1908 80 million carats have been mined At presently it is estimated that 75 of the diamond content is extracted Tour of the facilities The onshore mining area stretches from the Oranje River to a 100km land inwards and to the North Including the offshore operations the total mining area comes to a total of about 26000km2 of which the larger part is designated Sperrgebiet All diamonds mined originate from kimberlites in South Africa These were in time transported and deposited in river beds and to the sea by the the Oranje River The diamonds are found by tracing the characteristic sedimentary deposits onshore as well as offshore To accomplish this field data is obtained by using different exploratory techniques such as seismics (on- and offshore) and side scan sonar (marine) amp conventional sampling (on- and offshore) This data is used to make a geological reconstruction of the flow path of the Oranje River and incorporated into a model of the offshore currents which carry the sediments of the river towards the North When the current of a river is strong large sediments can be transported over long distances but as the velocity of the water decreases the large fragments are deposited and only the finer sediments can remain is suspension This is the reason that the larger diamonds are generally found close to their origin (inland mining operation) The smaller diamonds however may be transported over great distances (offshore mining operation) River erosion amp sedimentary processes have sorted these offshore diamonds to up to 98 gem quality they are retrieved from the marine gravel beds just off the coast of Namibia Unfortunately although we received permission to enter the Sperrgebiet the isolated mining area was allocated too far away to be incorporated in our 2 week visit of Namibia

The onshore deposits for the larger part comprise of excavation of the sand amp gravel located near the surface Further inland diamonds are occasionally liberated from their host rock by means of drilling amp blasting The mined material is then processed Processing involve the use of jigs cyclones sieve beds and x-ray sorters to separate the diamonds from the rocks After that the product is hand sorted to optimize the grade Land reclamation is carried out by landscaping the former mining area and creating dunes or other environmentally amp geographically acceptable landforms The offshore deposits are mined by large means of large dredging operations The vessels that are used for the dredging may differ in the exact method of mining but effectively they all transport sediment from the ocean floor to the surface and then transport the mined material to shore where it is processed in the same way as the onshore ore is done The concentrate from the mine the product after processing is transported to Windhoek where the diamonds are checked cleaned and sorted The process of cleaning and (hand) sorting at the Namdeb headquarters in Windhoek is strictly regulated Security is tight getting in yet even more so upon departure Any discomfort caused by this however is worth enduring The diamonds are cleaned by submerging them in strong acid bath This removes a greasy look Subsequently the diamonds are sorted in different ways They are mainly sorted by hand but also by a sorting machine When all the diamonds are sorted bagged and labeled they are sold to a London based diamond trading company Overall it takes about two months for a diamond to get from the deposit to the market
