The Homeguard showing is located 19.5 kilometres north of Alice Arm on the east bank of the Kitsault River. The area was extensively explored in 1916 for the source of mineralized boulders.

The region is underlain by an assemblage of volcanics and sediments comprising the Upper Triassic Stuhini Group and the Lower Jurassic Hazelton Group. These are folded into a doubly plunging north-northwest trending syncline and have been regionally metamorphosed to greenschist facies.

The showing is characterized by boulders, up to 10 metres in diameter, of brecciated Hazelton Group andesite containing calcite stringers and quartz breccia veins. The stringers are mineralized sporadically with pyrite and chalcopyrite and the veins, up to 2.13 metres wide, contain pyrite and chalcopyrite with minor galena, sphalerite and tetrahedrite. A 2.44 metre chip sample taken adjacent to an adit developed in one of these boulders assayed 34.28 grams per tonne gold, 110 grams per tonne silver, 2.9 per cent zinc, 2.0 per cent lead and 0.02 per cent copper (Property File - Silver Butte Mines Ltd. Annual Report 1970, page 6).

A narrow vein with similar mineralization, but not as pervasive as that shown in the boulders, was discovered in 1924 uphill from the boulders.

The original claims were located prior to 1916 and were known variously as the Homeguard, Central and Traveller. Early work included some tunnelling and trenching. In 1955 and 1956, Torbrit Silver Mines Limited carried out a resistivity survey, and completed 655 metres of diamond drilling on the ground which had been located as the Boulder group. In 1970, Silver Butte Mines Ltd. conducted trenching and blasting in the vicinity of the original workings.
