Mantaro Silver Corp. announced an initial work program on its high-grade silver San Jose Silver Property, located 180 km north of Lima, Peru. The San Jose Silver Property is comprised of five mineral concessions totaling 3,300 hectares. The San Jose Silver Property is a highly prospective silver property located within the prolific Miocene-Pilocene Epithermal belt. The Company anticipates that the San Jose Silver Property has an intermediate suphidation epithermal deposit. These deposits are characterized by vertical mineralization over 100's of metres and are usually high-grade in nature, which makes them attractive exploration targets. There are over 12 kilometers of veins and inferred strike extensions of veins. The veins are divided into four target zones: San Jose vein, El Sarco vein, UTCAS 1 vein and UTCAS 2 vein. The San Jose vein has approximately 200 meters of underground development on four levels. Veins are between 2-3 meters wide. The El Sarco vein is located 1,200 meters from the San Jose mine. Mapping has indicated average widths of over 1.0 to 1.5 meters over a strike length of over 1 kilometer. Historic surface channel sampling reported 2.8 to 3.4 ounces per tonne Ag, which is significant given veins are leached at surface. The UTCAS veins have returned results of up to 197 grams (6.3 oz) per tonne Ag over 1-2 meters, which is significant given weathered nature of veins in outcrop. From 2013 to 2018, a small scale underground mine was operation on the San Jose vein. An estimated 42,000 tonnes of material was extracted with reported silver grades between 15 to 20 ounces per tonne. Production exploited approximately 200 meters of the western margin of San Jose on four levels.
