The Allies showings occur at the headwaters of Green River just north of Mount Buttle over an area 2 by 0.6 kilometres. There is some overlap with the Close showings (092C 112) located about 1 kilometre to the north.

The area is underlain by volcanic rocks (greeenstone) of the Middle Devonian Nitinat Formation, Sicker Group. These volcanic rocks have been intruded by the Saanich granodiorite which is probably related to the Early to Middle Jurassic Island Plutonic Suite.

A series of subparallel quartz veins carry erratically distributed accessory amounts of pyrite, molybdenite and chalcopyrite. The veins crosscut a monzonitic (aplogranitic) marginal phase of the Delphi Lake/Saanich granodiorite stock. The veins, generally 10 to 30 centimetres wide but up to 1.5 metres, generally strike slightly west of north and dip steeply east. The sulphides occur as disseminations, and as coarse crystals or aggregates up to 10 centimetres across. Molybdenite occurs in flakes, clumps and rosettes from grain size to several centimetres across, most commonly as rosettes. The mineralization appears to be related to the emplacement of a late, high level monzonitic phase of intrusion into Nitinat Formation volcanics. The volcanics are preserved in a pendant on the ridge crest of Mount Buttle.

A grab sample (#14) taken from the higher grade pieces in a shear zone with fine molybdenite in the walls assayed 0.4 per cent molybdenum (Property File - Laanela, 1965).

Historical workings consist of 2 adits, a shaft and several trenches. In 1978, E. Specogna completed a program of prospecting on the area as the Close, Amore and Dibenedetto claims. In 1979, the claims were acquired by Aquarius Resources and a program of one diamond drill hole, totalling 10.9 metres, was completed near Summit Lake. A program of rock and soil geochemical sampling was completed the following year.
