Historic Small Scale Mining — Never Drill Tested
An estimated 2 km of underground workings have exploited only two small areas of San Jorge and Tembladera veins. To date 16 veins and major vein splays have been defined — with a cumulative strike extension of at least 12 kilometres.
Underground workings have provided access to some part of the San Jorge and Tembladera Veins — allowing Mantaro to conduct underground channel sampling of accessible veins.
