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

The showing is hosted by the Upper Triassic to Lower Jurassic Hazelton Group, Unuk River Formation metavolcanics. The Hazelton Group is a northwest trending steeply east dipping belt of folded andesitic lapilli tuffs, flows and breccia containing a thick sequence of argillite and siltstone infolded along a synclinal axis. The sequence is intruded by the Early Jurassic Texas Creek plutonic suite of dacitic porphyry dykes.

"Drilling on the Indi/Silver Coin Project indicated that the faulted off extension of the Main Breccia zone, which is interpreted as hosting the majority of the mineralization on the adjacent Big Missouri and Kansas claims has been traced for approximately 200 metres along the west side of Dan Hill in the eastern parts of the Indi 9 claim". (MD&A March 31, 2007)

The Dauntless Vein zone consists of a narrow quartz-carbonate-sulphide vein approximately 40 meters east of the Dauntless Hill zone that has been traced over a strike length of 500 meters. It consists of a vein that is 1-2 meters in width with approximately 10 % sulphides consisting of strong pyrite, sphalerite and galena and minor chalcopyrite. It strikes approximately north south with a steep west dip of 70-80 degrees.

The Dauntless Hill Zone consists of north-south trending steep cliffs of intense quartz-sericite-pyrite alteration cut by abundant quartz veins and random quartz stockworks. In the middle of a prominent hill on this zone, galena is present within the quartz stockwork over a width of 3 meters. Several hundred meters to the south, outcrops of intensely sericite-pyrite-quartz are extensions of the Dauntless Hill zone. To the north and on strike, en echelon stringers of quartz-pyrite-sphalerite over several meters of width may represent this zone. Overall width of the silicified zone may be 20-25 meters in the south with a feathering out of the zone towards the north. Strike length of the zone appears to be over 500 meters.

The property shares many characteristics with the nearby Silbak Premier Mine (104B 054), located just 5km to the south. In both locations mineralized zones are comprised of epithermal gold-silver-sulphide bearing siliceous breccias, stockworks, and veins."

Highlights from the 2005-06 diamond drill program on the Indi claim include 424.00 grams per tonne silver from 39.33 to 48.48 metres depth and 11.97 grams per tonne gold from 40.24 to 41.77 metres depth (www.pinnaclemines.com). DDH-2006-150–157 tested the Dauntless Hill zone.
