The Indian Mine is located on the Portland No. 1 and 2 Crown Grants, five kilometres north of the Silbak Premier Mine, 27 kilometers north of Stewart, B.C. Exploration on the property started in 1910 and sporadic minor production began in 1925 and continued until 1953. Esso Resources Canada Ltd. has recently investigated the area.

The property is located in the Intermontane Belt bounded on the west by the Coast Crystalline Complex and on the east by the Bowser Basin, in the volcanic arc assemblage of the Stikinia Terrane.

The deposit is hosted by Upper Triassic to Lower Jurassic Hazelton Group, Unuk River Formation metavolcanic rocks. The Hazelton Group is a northwest trending, steeply east dipping belt of folded andesitic lapilli tuffs, flows and breccia containing a thick sequence of argillites and siltstones infolded along a synclinal axis. This sequence is intruded by the Lower Jurassic Texas Creek plutonic suite of dacitic porphyry dykes and granitic Eocene Hyder intrusions. In the mine area remnants of country rock include breccia, tuffs and siltstone.

Mineralization was emplaced in the north trending Indian Fault system intermittently along strike (Indian Vein). The fault system contains pyritic, sericitic, quartz-calcite infilled fault breccia and gouge in an en echelon arrangement. The Indian Fault system generally dips steeply to the east striking 170 degrees and is believed to extend to the Payroll No. 4 (104B 050) Crown Grant, 450 metres north of the mine. Fracturing is abundant in the mine section and four distinct sets have been recognized, most of which are unmineralized. Economic mineralization appears to have been localized to areas where east dipping faults change direction and split into divergent branches, terminating where west dipping faults cut east dipping faults. The fault pattern differs between the mine levels. The level No. 2 faulting is mainly steeply west dipping.

Production from the mine was largely confined to the Indian vein (No. 1 level) which pinches and swells from 0.61 to 7.62 metres along a known strike length of 366 metres and a vertical range of at least 122 metres.

The "Hangingwall" vein exposed on the No. 2 level assayed 30.17 grams per tonne gold, 191.97 grams per tonne silver, 0.28 per cent copper, 4.62 per cent lead and 13.57 per cent zinc across 30 centi- metres (White, 1962).

The deposit consists of several lenticular, irregular fissure- type, sulphide bearing quartz veins which grade into irregular stockworks. Mineralization occurs in milky quartz and carbonate veins as open space fillings with coarse galena, sphalerite, trace tetrahedrite, chalcopyrite, covellite and pyrite. Silica, pyritic, carbonate, sericitic and potassic alteration is visible in the mine area. Host rocks are most intensely silicified near mineralization. Wallrocks include silicified porphyry and chloritic breccia.

Vertical zoning has been recognized from petrographic analysis. The abundance of sphalerite (and the iron content) increases, while chalcopyrite and galena abundance decreases, with depth. Generally, ore values decrease towards lower levels.

The Indian vein contains variable gold and silver values over narrow vein widths with low continuity. Mineralization in the mine area is considered to be late-stage infilling of fault breccia in young fault zones with coarse comb textures common. These mineralized fault zones have narrow zones of sericitic alteration. There has been no early-stage precious metal rich chalcedonic quartz stockworks similar to the Big Missouri deposit discovered on the property. The Indian mineralization is considered to be distinct and considerably later than the Big Missouri and Silbak Premier mineralization.

A diamond drillhole in 1984 intersected 8.95 metres of the vein and this interval assayed 57.9 grams per tonne silver and 2.14 grams per tonne gold (Assessment Report 13073). In 1936 a chip sample over 7.6 metres assayed 205.6 grams per tonne silver, 4.8 grams per tonne gold, 10.6 per cent zinc, 5.5 per cent lead and 0.2 per cent copper (Annual Report, 1936).

In 2009, grab samples yielded up to 79.80 grams per tonne gold (Kirkham, G. (2012-06-18): Technical Report on the Resource Estimate for the Premier Gold Property).
