Cerro Moro, Extorre Gold Mines Limited (95%) y Fomicruz (5%)

It is located 43 mi southwest from Puerto Deseado, in Santa Cruz province.

It hosts gold and silver mineralization. Cerro Moro is a low epithermal sulfidation where 30 veins have been identified. The veins of gold with silver at Cerro Moro are generally narrow (3.28 – 16.4 feet width) and sub-vertical. The high degree of gold and silver in the Escondida deposit has been tested in drillings of 1.24 mi. long and 656 feet deep.

The deposit counts with indicated resources of 578,000 oz of gold 38.800.000 oz of silver (1.350.000 oz of gold equivalent), inferred resources of 528,000 oz of gold and 26,200,000 oz of silver (1,050,000 oz of gold equivalent) This includes the contribution of the four new zones: Zoe, Martina, Carla and Nini. 76% of it contains 30 g/tn of gold or more; an exceptional number. The inferred resources mostly come from Escondida, Loma Escondida, Zoe, Martina, Carla, Gabriela, Esperanza and Deborah. In 2011, the indicated resources increased 46% and the inferred ones 166%, especially due to Zoe vein (79 g/tn of gold equivalent). Drillings in Esperanza made possible the discovery of the Nini vein, which contributed with almost a 20% of the inferred resources.

The Mining Project obtained the Environmental Impact Statement (E.I.S) by the Government of Santa Cruz The Preliminary Economic Study anticipates a useful life of 8.25 years and 1000tn/day in exploitation stage combining open pit and subterranean methods.

Olaroz Project, Orocobre Ltd.

This Project is located 167 mi. west from Jujuy city, 3,900 m.a.s.l. The average temperature is 8ºC and rainfall is minor to 100mm/year. The average speed of the wind is 15 mi/h. These conditions plus the low clouds are adequate for solar evaporation processes.

It mainly hosts mineralization of lithium and potassium. Olaroz is different from the rest in his species, since it is not dominated by halite. As a result, the specific yields of the sand and the stones are not rapidly reduced with depth; therefore, the zone under the clay layer (used as inferior limit of the current estimation of the resources) is an attractive goal for exploration.

The drilling has determined the salt lake of, at least, 656 feet depth. The basin reaches a depth of 1968 feet.
Resources and reserves are estimated in 6,400,000 tn of lithium carbonate and 19,300,000 tn of potassium. In 800 g/kl the average qualification of lithium is similar to Salar del Hombre Muerto and it approximately doubles the degree of the operation of Silver Peak and Salar del Rincón.

The construction stage will begin in September, 2012 in order to start the production in early 2014. US$ 250 M will be invested, having a production of 16,400 tn/year of lithium with the option to produce 10,000 tn/year of potassium by using 550 people during the constructions phase, and 270 people when the operation starts.
