The Sar 2 occurrence is located on the northeastern flank of Pachena Cone, approximately 2.0 kilometres south of Sarita Bay.

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 fractured and brecciated zone, approximately 25 metres wide and traced for 150 metres, cuts the intrusive. Silicified and pyrite rich veins and breccia zones occur within this larger zone.

In 1985 a program of airborne magnetic and VLF-EM surveys was conducted by Amvic Resources Limited on the Sigma 3 claim. 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 zone assayed up to 0.14 per cent copper and was anomalous in gold, silver and zinc (Assessment Report 18773).
