The Pinto showing is located on the north side of the Stikine River about 2 kilometres downstream from the mouth of the Tahltan River, approximately 14 kilometres north of the community of Telegraph Creek.

The showing area is underlain by the Late Triassic to Early Jurassic Copper Mountain Plutonic Suite comprising a zoned body of pyroxenite, pyroxene syenite and syenite rich in apatite and magnetite. There is no information on mineralization but the National Mineral Inventory card indicates copper as the primary commodity. It is assumed to be disseminated chalcopyrite.

Exploration appears to have focused on copper, silver, gold, titanium and cadmium minerals/commodities.
