The Hooker Pass occurrence is located north of Hooker Pass at an elevation of 2235 metres.
The area is underlain by Middle Proterozoic rocks of the Purcell Supergroup and by Upper Paleozoic rocks of the Windermere Supergroup. Windermere rocks include conglomerate of the Toby Formation and quartzite, limestone, arkose and pebble conlgomerate of the Horsethief Creek Group. Purcell rocks include laminated argillite, dolomite and quartzite of the Mount Nelson and Dutch Creek formations.
Locally, a dolomitic limestone of the Mount Nelson Formation hosts quartz veins and stock works with galena, tetrahedrite, azurite and malachite mineralization.
In 1980, two samples (HP-4 and HP-5) from the Hooker Pass zone yielded 0.91 and 1.76 per cent copper, 2.80 and 0.33 per cent lead, and 0.76 and 1.02 per cent zinc with 3146.4 and 2975.4 grams per tonne silver, respectively (Assessment Report 10463).
The area has been historically explored in conjunction with the nearby Commonwealth (MINFILE 082FNE162) occurrence. In 1979, a program of prospecting and silt and soil sampling was completed on the area. In 1980 and 1981, Greenwich Resources completed programs of rock and silt sampling, geological mapping and a ground electromagnetic survey on the area as the Hidden Treasure and Hooker claims. In 1987, Rival Minerals completed a program of soil sampling and a 37.0 line-kilometre combined ground electromagnetic and magnetic survey. In 2008, a soil sampling program was completed on the area as the Late 1-3 claims.
