The A-2 occurrence is located on an east-facing slope, south of Dupuis Creek and west of Mamit Lake.

The area lies near the eastern border of the Upper Triassic to Lower Jurassic Guichon Creek Batholith. The area is underlain by coarse-grained quartz diorite to granodiorite of the Border phase, which grades westward to younger, medium-grained Guichon variety granodiorite of the Highland Valley phase of the batholith. To the east the intrusive rocks are in contact with sedimentary and intermediate volcanic rocks of the Upper Triassic Nicola Group. The contact strikes north and dips steeply and is marked by high-grade metamorphism.

Locally, sericite-, kaolin-, chlorite- and potassium feldspar-altered dioritic and quartz monzonitic rocks host variably amounts of pyrite, chalcopyrite and magnetite as disseminations and fracture fillings.

In 1969, a drillhole (A-2 69-1) is reported to have yielded 0.19 per cent copper over 51 metres, including 0.41 per cent copper over 15.2 metres, whereas another drillhole (A2-2) yielded 0.11 per cent copper over 5.7 metres (Property File - 843263).

In 1972, a drillhole (72-5) yielded 0.32 per cent copper over 3 metres (Property File - 10609).

Drilling on this area, in 1999, intercepted a weakly potassic-altered granodiorite with weak to moderate propylitic (quartz-chlorite-pyrite-magnetite) overprinting and possibly later weak argillic (quartz-pyrite-clay) alteration with trace fine-grained chalcopyrite mineralization in thin fractures. Assays were negligible (Assessment Report 25971).

Work History

Copper mineralization was first discovered in the area around 1914 and subsequently several hand trenches and two or more shallow shafts were excavated.

During the late 1960s and early 1970s, program of geological mapping, geophysical surveys, trenching and diamond drilling were completed on the area as the MLM claims.
