The Iron-Kitsault showing is located 1.25 kilometres northeast of the West Kitsault River, 29.5 kilometres north-northwest of the town of Alice Arm.

The showing consists of several shear zones hosted in plagioclase hornblende porphyritic andesite of the Jurassic Hazelton Group. The porphyry is thought to be the intrusive equivalent of the felsic Mount Dilworth Formation.

One 3.7 metre wide shear zone contains abundant pyrite and chalcopyrite. A second 3.7 metre wide shear zone, 76 metres to the east, strikes 070 degrees and dips 90 degrees. This zone is mineralized with pyrite and chalcopyrite and minor galena and sphalerite in a gangue of quartz and calcite. A grab sample of well mineralized quartz from this shear zone assayed 3.98 grams per tonne gold, 295 grams per tonne silver and 2.0 per cent copper (Minister of Mines Annual Report 1922, page 57).

In 2003, Bravo Venture Group Inc. acquired the Homestake Ridge and focused its drill program primarily on structurally controlled gold mineralization (Homestake, 103P 216) in the Goldslide pluton rather than exploring for a precious metal enriched volcanogenic massive sulphide (VMS) deposit as Teck Cominco Ltd. had. Six holes tested a zone of quartz-pyrite stockwork veining and breccia at the contact of the feldspar-hornblende porphyry stock. Bravo drilled five additional holes to test four other targets: the rhyolite/argillite contact formerly explored by Teck Cominco, the Silver Crown zone (103P 082), and the Fox-Gold Reef zone (103P 093, 213), and the Dilly vein. No significant assays resulted. During the 2004 field season, Bravo focused on delineating the strike potential of the main Homestake shear. Ten line-kilometres of cut grid were established over the main and adjacent structures. Soil sampling and ground magnetic geophysics were conducted over the grid. Several zones of interest were identified mapped and sampled. In 2005, Bravo returned to the Homestake Ridge gold prospect (103P 216) to complete 1643 metres of drilling in 11 holes, intersecting significant gold-silver values.

During 2017 through 2019, Auryn Resources Inc. completed programs of geological mapping, geochemical (rock and soil) sampling, airborne and ground geophysical surveys and re-logging of historical drill cores.

Please refer to Homestake (103P 216) for further details of the larger property and area.
