The Gold Vein occurrence is located on the northern slopes of Hecate Mountain, at approximately 760 metres elevation, 27 kilometres southwest of Port Alberni.

The area is underlain by Upper Triassic Quatsino Formation (Vancouver Group) limestone in contact with andesite of the Lower Jurassic Bonanza Group. The strata is intruded by diorite of the Early to Middle Jurassic Island Plutonic Suite. The intrusive has altered the limestone to masses of garnet and epidote, while the andesite is intensely fractured and metamorphosed, containing bunches and stringers of garnet, epidote and tremolite.

Locally, siliceous and altered limestone in or near contact with volcanic and intrusive rocks hosts copper (chalcopyrite?) mineralization.

In 1988 and 1989, Barona Resources completed programs of soil and rock sampling, geological mapping and ground geophysical surveys on the area as the Gold Nugget claim. Two chip samples (D2754 and D2755) assayed 94.5 and 17.9 grams per tonne silver, greater than 1 per cent zinc and 0.26 per cent zinc with greater than 1 per cent copper, respectively (Assessment Report 17714).

In 2007 through 2013, Nahminto Resources completed a program of prospecting, geological mapping, geochemical sampling, a ground magnetometer survey and airborne geophysical surveys on the area as the TJM claims, part of the Nahmint property. In 2013, Equitas Resources Corp. conducted geological mapping, rock, soil and stream moss mat sampling at the Three Jays North area of the Nahmint property.

In 2020 a structural analysis via photo interpretation and minor prospecting and stream and rock sampling were conducted on the Nahmint property for tenure holder B. McKinney.
