The Archer occurrence is located on the western flank of Mount Vernon, north of Raymond Creek.

The area is underlain by extensively faulted rocks of the Upper Triassic Vancouver Group and the Lower Jurassic Bonanza Group. The basal Vancouver Group sequence is comprised of basalt flows, breccias and tuffs of the Karmutsen Formation overlain by Quatsino Formation limestone, which in turn is overlain by black argillites of the Parsons Bay Formation. The overlying Bonanza Group consists of a sequence of argillites, cherts, cherty tuffs, volcanic and/or sedimentary breccias, sandstones and basaltic to rhyolitic flows.

The overall package of rocks have been broadly to tightly folded with fold axes generally trending northwest, and have been intruded by granodioritic and feldspar porphyritic dykes.

Locally, a pyritic fracture/shear zone occurs in dacite (possibly siliceous andesite) and chert of the Bonanza Group. Pyrite occurs as stringers and fine to coarse disseminations. Some calcite and epidote veinlets are also evident in this zone. Several massive pods of pyrite up to 1 metre thick occur locally in bedded chert; minor magnetite was also observed. Drill core from holes intersecting this zone assayed up to 2.8 grams per tonne gold and 11.5 grams per tonne silver (Assessment Report 17164).

In the 1960’s, the area was originally explored by Avallin Mines and later Quintana Mines. In 1988, Nuspar Resources completed a program of geological mapping and five diamond drill holes, totalling 113 metres. In 2010, the area was staked and prospected as the Zodiac, Constitution, Libra and Marigold claims by D. Arbic.
