Cornerstone has been exploring in Ecuador since 2005 through its wholly-owned subsidiaries, Cornerstone Ecuador S.A. (CESA) and La Plata Minerales S.A. (PLAMIN). The Company has a portfolio of drill-ready projects in Ecuador targeting epithermal gold-silver and porphyry copper-gold deposits. An important part of the future valuation of Cornerstone derives from its minority financed interest in the Cascabel copper gold project in northern Ecuador, where drilling is ongoing and where fifteen high-priority porphyry centres are now recognized within the project. On January 3, 2017, the Company and its majority joint venture partner SolGold Plc announced a maiden mineral resource estimate for the Alpala deposit of 430 Mt @ 0.8% Copper Equivalent (CuEq) Indicated and 650 Mt @ 0.6% CuEq Inferred (3.4 Mt CuEq Indicated 4.0 Mt CuEq Inferred) at 0.3% CuEq cut off. (For more details, see Cascabel page). Cascabel is located in north-western Ecuador in an under-explored northern section of the richly endowed Andean Copper Belt, 60 km northeast of the undeveloped inferred resource of 982 million tons at 0.89% Cu Junin copper project (0.4% Cu cut-off grade; Micon International Co. Ltd. Technical Report for Ascendant Exploration SA, August 20, 2004, pages 28 & 29). Mineralization identified at the Junin copper project is not necessarily indicative of the mineralization on the Cascabel Property. On March 6, 2017, Cornerstone announced that its joint venture partner, Ecuador State Mining Company ENAMI EP, had been granted a number of mineral concessions in Imbabura and Carchi provinces in the same area as the Cascabel and the Llurimagua concessions, for exploration by the ENAMI-CESA strategic exploration joint venture. Nine concession titles totaling almost 40,000 hectares were granted in 2017 by the Ministry of Mining (please see ENAMI Strategic Alliance page). The Company has two wholly-owned exploration projects located in southern Ecuador, the Bella Maria and Vetas Grandes projects, as well as one property, Caņa Brava, in which it has the right to earn 100%. The Vetas Grandes gold prospect is strategically located approximately 15 kilometres west of the Loma Larga (formerly called Quimsacocha) high-sulphidation epithermal gold-silver-copper deposit, south of the Rio Blanco low-sulphidation gold-silver deposit and southeast of the Chaucha porphyry copper-molybdenum deposit. On all three projects, the Company has identified sizeable altered and mineralized zones which offer good potential for new discoveries. The Company also has a joint venture with Sunstone Metals Inc. on the drill-ready Bramaderos property in Loja Province (please see Bramaderos Property page).
