The Adam Northwest occurrence is located at an elevation of approximately 650 metres on a northwest-facing slope, southwest of the Adam River and approximately 3.4 kilometres southwest of the west end of Keta Lake.

The area is underlain by Upper Triassic Vancouver Group rocks composed of a thick sequence of tholeiitic basalts of the Karmutsen Formation and overlying carbonates of the Quatsino Formation. The Vancouver Group rocks are intruded by granodiorite of the Jurassic Island Plutonic Suite.

Locally, a basalt hosts a 5-metre-wide zone of flat-lying and north-dipping quartz-potassium feldspar-epidote veins with fine-grained bornite and chalcopyrite as fine disseminations and filling amygdules.

In 2019, three rock samples (19098, 19099 and 19175) yielded from 0.461 to 2.300 per cent copper, 2.1 to 13.2 grams per tonne silver and 0.008 to 1.125 grams per tonne gold (Assessment Report 39053).

In 2020, two rock samples (27457 and 27458) yielded 0.963 and 2.550 per cent copper, respectively (Assessment Report 39283).

Another zone of mineralization, located approximately 400 metres to the northeast of the main zone, comprises a basalt hosting fine-grained chalcopyrite.

In 2019, a rock sample (19176) assayed 0.708 per cent copper and 4 grams per tonne silver (Assessment Report 39053).

A third zone of minor mineralization, located approximately 650 metres north-northwest and across the creek valley from the main zone, comprises narrow (0.5-centimetre-wide) quartz veins with bornite hosted in a basalt.

In 2019, a rock sample (19184) assayed 0.982 per cent copper (Assessment Report 39053).

Work History

The area has been explored in conjunction with the nearby Adam West (MINFILE 092L 222) occurrence and a completed regional exploration history can be found there.
