2. CORPORATE

Management focused during the quarter on advancement of the Company‟s three projects:

Cerro del Gallo, Namiquipa and Mt Philp; advancement to acquisition of the new Espiritu Santo

Jalisco project; and completion of the statutory audit plus preparation and publication of the

annual report to stakeholders.

* Sample was re-assayed using four methods, including as a concentrate, at ALS in Vancouver and it should be noted that core

recovery was within fault zone with 50 to 70% core recovery.

Cerro Resources Project Location Map

Cerro del Gallo

Near final assessments of the crushing and processing plant were made at quarter end having

taken advantage of time delays with third party design of plant, pad and pond designs. These

have been momentarily delayed to allow some further site assessment in order to ensure the

site layout can accommodate the potential increase in open pit heap leach resource due to

potentially increased metal recoveries and longer term higher metal prices. The additional site

assessment work is due to take place mid-November, which will allow finalisation of the pad and

pond design and costing as the last of the outstanding inputs to the bankable feasibility study

(BFS).

Meanwhile the time has been useful for running further recovery tests to improve confidence

and de-risk the project. The high pressure grinding rolls (HPGR) were reported upon last

quarter and the recovery levels have been confirmed this quarter (Table 1). Details of the

change in production forecasts from these increased recoveries are shown in Table 2.

* As previously reported in the NI43-101 technical report titled “Feasibility Study

and Preliminary Assessment Cerro del Gallo Project Guanajuato, Mexico” and lodged

26 May 2011.

The actual HPGR test work recoveries for silver are significantly higher than previously. For

cash flow projections, more conservative recoveries are being used for the base case since

silver mineralogy and therefore recoveries by cyanidation can be more variable. For the design

work we use the higher silver recoveries to ensure an adequate allowance for the potential

increased amount of silver metal. Merrill-Crowe test work was investigated and has been

discounted due to the presence of copper. This process is not the optimum hence design

parameters have now been determined for the use of carbon for metal recovery from heap

leach solutions (CIL), where the presence of copper is more easily managed. These parameters

are being reconfirmed with the higher silver levels present.

The HPGR laboratory trials have been completed allowing the HPGR unit to be sized and

costed by Polysius. The test work has confirmed the production of material of the required size

distribution from HPGR crushing (80 per cent passing 4.4mm). This is finer than the originally

targeted 6.3mm by conventional and will give greater confidence that recoveries achieved by

the column tests can be realised in practice. To ensure the heap leach will have the required

permeability with the fine crush size, further agglomeration test work using cement has been

completed and two additional column leach tests have commenced. The columns are 6 metres

high and are filled with the HPGR crushed material with the 80 per cent passing 4.4mm crush

size. These tests are confirmatory tests to provide additional support information for the BFS.

Namiquipa

Drilling commenced late May 2011 and at the end of June 8 holes for a total of 2,800m of

diamond core had been completed. During the September quarter a second drill rig was added

and a further 26 holes for a total of 9,300m of drilling was completed with very encouraging drill

intercepts.

First results were released early August and returned good silver, lead and zinc grades as

shown in table 3 below.

US$1.00/lb Lead. Metal recoveries are not considered in this calculation. Further drilling is required to provide a more accurate

assessment of vein thickness and true width may vary.

The program was extended from 10,000m to 20,000m minimum and the intention is to continue

the program beyond that level.

The first rig is drilling to test potential extensions of the vein mineralization from the historic La

Venturosa Mine – which produced an estimated 14.4 million ounces of silver, 32,550 tonnes of

lead and 43,530 tonnes of zinc from two prominent quartz/breccias vein systems; the America

and Princesa. The drill results to date indicate the mineralized system continues at depth along

the Princesa vein system with the geological setting suggesting significant potential for high

grade material to be hosted in additional vein spurs/shoots.

The second core rig has focused on exploration of possible extensions of the known systems as

well as testing for new systems to the north, south and to the east of the known vein systems.

The Silver equivalent grades (“AgEq”) in tables 4 to 8 have been calculated using metal prices of US$25oz Silver; US$1.00/lb

Zinc; and US$1.00/lb Lead. Metal recoveries are not considered in this calculation. Further drilling is required to provide a more

accurate assessment of vein thickness and true width may vary.

The Namiquipa vein systems (Figure 1) are „blind‟ in that they are not all evident at surface. The

early success and encouraging drill results is however sufficient for management and

shareholders to be encouraged.

Espiritu Santo Jalisco

The Espiritu Santo Jalisco project was secured at the end of the quarter and announced on 7th

October, 2011. The project is in Jalisco State in central western Mexico and was targeted

because of the historic workings in the broader region of Jalisco State and also given no

modern exploration has been undertaken following historic soil and rock-chip sampling. Historic

rock-chip sampling confirmed the presence of gold and silver in numerous epithermal veins as

show in table 9.
