The COPPERCAP showing is located on the Chilcotin Plateau, approximately 6 kilometres north of Gaspard Lake and 80 kilometres southwest of Williams Lake, B.C.

Regionally, the area is underlain by tonalite of the early Cretaceous Mount Alex Plutonic Complex, calcalkaline volcanic rocks of the early Cretaceous Spences Bridge Group and overlaying basaltic volcanic rocks of the Miocene to Pleistocene Chilcotin Group.

The occurrence, discovered on a logging road in 2010 and trenched in 2011, consists of narrow cross-cutting calcite veinlets containing traces of coarse-grained chalcopyrite and a central zone of chalcopyrite-bearing chlorite-altered hornblende granodiorite in contact with an andesite dike.

In 2010, the area under the Coppercap claims was prospected by B. Johnson. This work led to the discovery of anomalous copper-bearing sub-outcrop and outcrop. Samples of mineralized hornblende diorite returned values of up to 9497.0 parts per million copper, 14.4 parts per million silver and 15 parts per billion gold (Assessment Report 32386).

In 2011, Plateau Minerals Corp. completed a short trenching and geochemical sampling program on a new discovery approximately 1200 metres west of Minfile NORTH FAME. Trench 1 averaged 302 parts per million copper over its entire 120 metre length with a central zone that graded 0.29 per cent copper over 6 metres. The higher copper grades are associated with wispy chalcopyrite, in chlorrite-altered and pyritic hornblende diorite to granodiorite (Assessment Report 32642). In 2012 and 2013, Plateau Minerals Corp. and Brocade Metals Corp. followed up with programs of soil sampling and magnetics.

In 2017 and 2018, B. Kreft and son undertook soil and rock sampling in the COPPERCAP area, returning values of high anomalous copper and to a lesser extent gold and molybdenum values.

A complete regional exploration summary can be found under the Fame (MINFILE 092O 019) occurrence, which is located approximately 2.5 kilometres to the south.
