The Close showing is located just west of Delphi Lake, 32 kilometres southwest of Nanaimo. The Close claim covers the northern Allies showings (092C 014).

The area is underlain by volcanic rocks of the Devonian Nitinat Formation, Sicker Group intruded by Early to Middle Jurassic Island Plutonic Suite rocks. Major northeast and northwest striking faults have resulted in fracturing of the intrusive rocks. These fractures are generally quartz-filled and some host mineralization.

Mineralization consisting of molybdenite, chalcopyrite and pyrite occurs in siliceous veins and shears in intrusive rocks and disseminated in adjacent volcanics. Molybdenite occurs sparsely disseminated in fissures, veinlets and veins up to 1.5 metres wide over an area 2 by 2.5 kilometres. The veins strike between 320 and 360 degrees with dips between 65 and 85 degrees east.

One crosscut and several trenches were opened in the early 1900's (probably part of the Allies workings). In 1976, Echo Minerals completed a program of silt sampling on the area as the Skyline claims. 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. A sample from a 41 centimetre quartz vein assayed 0.625 per cent molybdenite and 0.556 per cent copper (Assessment Report 8782).
