The Adam Southwest occurrence is located at an elevation of approximately 680 metres on a northwest-facing slope, west of the Adam River and approximately 3.7 kilometres southwest of the west end of Keta Lake.

The area is underlain by Upper Triassic Vancouver Group rocks comprising 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 mafic volcanic hosts magnetite and malachite.

In 2020, a rock sample (27252) assayed 1.93 per cent copper (Assessment Report 39283).

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.
