The Sar 1-2 occurrence is located to the west of the Port Alberni-Bamfield Road, approximately 1.5 kilometres southeast of Santa Maria Island.
The area is underlain by carbonate rocks of the Upper Triassic Quatsino Formation, Vancouver Group and volcanic rocks of the Lower Jurassic Bonanza Group. These have been intruded by Early to Middle Jurassic Island Plutonic Suite granitic rocks. The structural trend is northwest with easterly dips.
Locally, a skarn zone hosts pyrite, pyrrhotite and chalcopyrite mineralization within a silicified limestone, associated with a small plug of Island Intrusives. In close proximity to this skarn, the intrusives contain small (up to 3 centimetres wide) pyrite rich silicified zones.
In 1980, Rainier Energy Resources completed a program of geochemical sampling on the Dan claims. In 1989, the area was staked as the Sar 1-2 claims by W. Halleran and a geochemical sampling program was completed. Sampling of the skarn has assayed up to 0.036 per cent copper (Assessment Report 8459).
