The Bingo occurrence is located at the head of the Leech River, approximately 1.5 kilometres north of Weeks Lake in the Sooke Hills.

Regionally, the area is underlain by the Survey Mountain fault, which forms the boundary of the Mesozoic and/or Paleozoic Wark Gneiss on the north, and the Jurassic to Cretaceous Leech River Complex (Formation) on the south. Rocks of the Wark Gneiss are reported to consist of chloritized diorite and gneissic dioritic. The Leech River rocks consist of well-foliated chlorite-sericite schist, sheared argillite, chert and volcanic breccia.

Locally, the Survey Mountain fault forms a zone, almost 300 metres wide, striking 130 degrees and dipping nearly vertically. The zone consists of several large graphitic shears and faults, three main ones, all hosted by the volcanic units of the Leech River Complex.

In 1987, a sample taken from one of these shears consisted of irregular stringers of quartz in brecciated graphitic schist. The sample was taken over a 2 metre interval and assayed 9.60 grams per tonne gold, 10.28 grams per tonne silver, and 0.01 per cent copper (Assessment Report 18848). In 1990, a sample (1628) from the same zone returned 10.9 grams per tonne gold (Assessment Report 22495).

From 1987 to 1991, Abacorn Resources Inc. completed exploration programs of geological mapping, geochemical soil surveys and geophysical surveys on the Bingo claims. From 1992 to 1996, Boston Capital Corp., later Boston Industries Inc., completed programs of prospecting, geological mapping and geophysical resistivity surveys on the claims.
