Pilar Grande Mine
Copper-Silver mineralization in a 23 meter (75’) thick stratigraphic interval comprising the lowermost 10 meters of the “Cupido” limestone unit (Levels 1 and 2) and the uppermost 13 meters of the underlying hematized sandstone sequence (Levels 3 and 4). The workings extend for 150 meters along strike and 50 meters down dip, grades up to 5.86 % Cu / 901 g/t Ag. Average 2.5% Cu and 118 g/t Ag. Current 1000 metres underground development
2018 – 2019 Exploration Drilling
The drilling at Pilar Grande tested the mineralized horizon over a strike length of 180 meters with 11 diamond drill holes, for a total of 1,273 meters. Copper oxide and sulphide mineralization was intersected in all but holes DI-18-04 and DI-19-06. The Cu-Ag mineralization transitions from the oxide zone into the predominantly sulphide rich zone down dip to the northwest. The zone remains open down dip and along strike to the north and south. The access roads to the drill platforms were built onto the talus at the base of the mountain flank. The lack of talus material at both extremities of the drilled area prevented the drilling to extend further during this first phase.
