2 OUR OBJECTIVESA start-up plan for a pilot mining operation on the Granizo-Madero mining concessionsA plan for intensive exploration aimed at the identification of a resource base to scale the pilot output of mineralized rock feed from 500 to 2000 tpd(The above is based on non compliant estimated resources from Molycomex’s* previous exploration programs on the outcropping Cu-Ag manto deposits, together with investigations and tests on the treatment of the raw materials by a heap-leach process)*Moly comex S.A. De C.V. Is a registered Private Limited Corporation in Mexico
3 BACKGROUNDMolycomex learned of the Copper-Silver deposits of this area in 2009 during regional exploration and decided to acquire the El Madero (Apache) (southeast sector) property, as well as inner plots of landIn 2011, an intensive exploration was initiated by 1:20:000-scale geological mapping and semi-detailed geological mapping of 4 richer Cu-Ag manto zones>3000 heavy equipment machine hours used to construct and restore access roads and excavate 139 trenches along the Cu-Ag mantos449 channel samples sent to ALS Chemex (Canada) for full assayThirty DDHs planned and 4 were drilled at San Antonio, with excellent resultsUsing the 2011 exploration data, NI Technical Report was issued by Dahrouge Geological Consulting (Prof. Roger D Morton P.Geol and Janine C Brown P.Geo)
4 The El Granizo-El Madero Projects The El Granizo-El Madero mining exploration projects are located in the Cuatro Ciénegas Municipality, in the ejidos (communal agricultural sectors) of Santa Teresa, Tanque Nuevo, Cuates de Australia, and Estanque Palomas in the portion known as Rancho El Jabalí.The El Granizo area was explored at different times, most recently by an exploration and drilling program performed by BHP in 1995During a Noranda/Outokumpu JV explored the Cu-Ag mantos of the San Marcos and Pinos Sierras and the El Granizo Sierra. The program included regional mapping and detailed work on the El Granizo, Adrianas, and Don Indio areasThe current property consists of 11 mining concessions covering 18,267 hectares These concessions cover a Cu-Ag manto belt >50-km long with more than 35 potential mining sites (with old shafts and recent trenching); see NI The mantos are 1.5 to 9.6 meters thick. Copper grades vary from 0.5% to 2.4 % (grades that could be feasible to support low-cost mining and extractive operations)
5 Manto outcrops are as long as 250m Manto outcrops are as long as 250m. The principal ones being: Granizo (Manto Negro), Las Nieves, Ojitos, San Antonio, and Buena Suerte (but also including Las Emes, Juanitas, El Pilón, Tajo Zanja, and Don Indio)The mineralized host-rocks are sandstones and dolomites of the Lower Cretaceous San Marcos Formation. Mineralized zones are also found in dolomites of the Cupid FormationThe fundamental objective of this presentation is to illustrate the benefits of an early start-up of pilot mining operations on the major mineralized zones of Granizo (Manto Negro), Ojitos (Feeder Vein), the San Antonio manto and the Buena Suerte mantoThe initial plan is to make lateral open-pit excavations along the strike of the strata/mantos, up to the limits defined by overburden thickness vs. ore cost-benefitsFrom experience gathered from trenching and general excavations on the Ojitos, San Antonio, and Buena Suerte sectors, it was found that these stratiform manto zones can be strip-mined using a simple excavator and jack hammer to provide a good yield of mill feed per day
6 We estimate that strip mining using heavy-duty machinery can be effective up to 35m behind the current outcrops with a strip ratio of 7:1Subsequently, room and pillar mining would be implemented as is shown on the following figure:
7 Estimated Mineral Inventory: In 2011, Molycomex estimated the mineral inventories at the major sampling sites and drill sites in the Madero Area to be as follows:10 drills are planned on the Madero Concession (see Fig 26-1 technical report Madero Property) throughout 1 km of outcrops. These drillholes, above and beyond checking for mineralization continuity, are targeted to expand mineral inventories by >1 million tonnes at the above-mentioned Cu grades.A similar operation was performed by BHP at the Granizo Manto Negro sector using data from trenching and RC drilling. The average content was calculated using a density of 2.4 for sandstone. A 200m-long mineralized block was calculated, with an estimated width of 50 meters and 7 meters thickness, for an estimated total of 150,000 tonnes with 1.1% copper.Thus we conclude an Current Estimated Mineralized Rock Inventory: 240,000 tonnes

10 Mining plan and heap leach Part 1: The initial estimate of the mineral inventory is 240,000 tonnes (NI Non Compliant), but this only takes into account the 4 sites where exploration is most advanced, namely: Manto Negro, San Antonio, Buena Suerte, and Ojitos. This provides sufficient ore to feed a start-up plant to process 500 average 1% Copper. The targets of the additional proposed exploration program would ideally be discovery of:Year million tonnes of ore with % copperYear million tonnes of ore with % copperYear million tonnes of ore with % copperThe growth of the mineral inventory resulting from exploration could provide and increment the daily processing of the plant from 500 to 1000 tonnes/day and then by year 3 ideally double that to % Copper.Molycomex’s Column leaching tests (see technical report Madero Property, fig & 13-2) showed a recovery of 90% after grinding down to -1/4”. Thus with a production of 1000 tonnes/day with a 1% Cu head grade at a recovery rate of 90%, the projected output in copper cement would be 9 tonnes of copper per day, at a selling price of US$3/lb this infers a gross yield of US$59,400.00/day or US$1,782,000.00/month.
11 Mining plan and heap leach Part 2: Given the results of the original metallurgical test, it is advisable to perform other tests on -1/2” and -1” grain sizes, also varying the sites of samples to be checked. This will optimize the grinding size and the eventual recovery ratio; thus, primary (jaw) and secondary (cone) crushing is planned, using portable power equipmentIn the already approved Environmental Impact Assessment study of the Granizo area the first stage contemplated involves building a 2.5 hectare heap pad, with a 1.5-hectare (15,000 m2) heap leach operation. This leach pad will have a projected capacity of 500,000 tonnes, which at a throughput rate of 1000 tonnes/day will have a life of 1.5 years in the first stageStorage tanks are required for the Pregnant Leach Solution (PLS), depleted solution (DS) tanks, and a fresh water (FW) tank. Also required are a storage facility, drying area (press filter), workshop, fuel tank, a sulphuric acid (H2SO4) reservoir and a few minor civil worksIn addition to the leaching heap, precipitation or cementation zones will be built, consisting of ramps in the shape of shallow pools at -6° to -9° angles. These ramps are made of reinforced concrete with epoxy coating to protect against low pH solutions that contain copper
