The Excise, 3.5 kilometres by steep road southeast of Camborne and west of Mohawk Creek, is similar to a system of mineralized veins along the south side of Pool Creek. See the adjoining Spider (082KNW045) and Eclipse (082KNW044).

The area is underlain by volcanic and sedimentary rocks of the Lower Paleozoic Lardeau Group. Sedimentary rocks of the Broadview Formation include medium grey to greenish quartzites, greywackes, carbonaceous phyllites and quartz sericite schist. The volcanic rocks of the Jowett Formation comprise massive fragmental lenses and lava flows, some chlorite schist and a few thin beds of banded iron formation.

Quartz veins, cutting the metasediments, contain galena, sphalerite and pyrite. One vein strikes 165 degrees and dips 50 degrees east. Samples assayed up to 1371 grams per tonne silver, 1.7 grams per tonne gold, 48.5 per cent lead and 5.5 per cent zinc; a 3.35-metre sample assayed 68.6 grams per tonne silver, 2.7 grams per tonne gold and 0.8 per cent lead (Annual Report 1914, page 261).

Underground workings total over 130 metres. An outcrop of galena was discovered on the hillside about 60 metres above Mohawk Creek in about 1910. Two claims the Excise and Duty were staked and exploration work began in open cuts and adits. Multiplex Mining, Milling and Power Company, Limited purchased a controlling interest in the property in 1917 and some development work was carried out the following year. The property was developed by three adits, exposing the vein to a depth of about 45 metres below the outcrop.

In 1986, Ram Explorations Ltd. drilled 5 holes totalling 410 metres. In 1988, they drilled 3 holes totalling 272.8 metres.

In 2016 and 2017, Explorex Resources Inc. completed programs of prospecting and rock and soil sampling on the area as the Silver Dollar property. In 2019, Mariner Resources Corp. completed a 624 line-kilometre airborne magnetic and radiometric survey on the area as the Silver Dollar property.
