The showings are at about the 500 foot elevation in the bottom of a steep south-flowing tributary of Riley Creek.

The showings were originally reported in 1918 and were staked in 1942 by V. Courte when it received some examination and a little channel sampling.

The area is underlain by Middle Jurassic Yakoun Group rocks dominated by pyroclastic andesites and lesser massive andesite, conglomerates, volcanic sediments and argillites. Thinly bedded to massive sandstone and minor conglomerate of an unnamed formation of Cretaceous age are in fault contact with Yakoun rocks just east of the occurrence (GSC Open File 2319). These units are cut by quartz diorites and porphyritic felsic dikes.

The dominant structure on the property is a major west northwest trending fault zone (Rennell-Louscoone fault system), with associated splays and subparallel faults. Locally, a vertical dipping fault striking 150 degrees appears to control the emplacement of rhyolitic feldspar porphyry dikes and related mineralization and alteration. Sericite-clay-carbonate-minor silica alteration occurs in an area up to 500 metres long and 120 metres wide. Individual zones of alteration vary from a few tens of metres to over 70 metres in width and are associated with faults and dikes. The abundance of carbonate in the area may express mobilization of the limy fraction of the underlying Juro-Triassic Kunga Group.

Sulphide mineralization occurs in the alteration zones and in stockworks of irregular quartz and calcite veinlets developed in feldspar porphyry dikes. Mineralization consists of pyrite, arsenopyrite, and stibnite, with minor pyrrhotite, chalcopyrite, sphalerite, and galena.

A chip sample of continuous exposure in Sol Creek assayed 1.37 grams per tonne gold and 0.4 per cent antimony over 95 metres (Assessment Report 24981, page 8). A drill hole 425 metres east-southeast from mineralization exposed in Sol Creek assayed 1.37 grams per tonne gold and 0.23 per cent antimony over 10 metres (Assessment Report 24981, page 8). A 1971 survey indicated a 70 by 300-metre area in which the surface grade was estimated to be 1.4 grams per tonne gold and 0.40 per cent antimony (Assessment Report 8225). A 2.27 kilogram sample, taken by Luke Watson in 1942, assayed trace gold, 19.2 grams per tonne silver, 0.1 per cent lead, 0.2 per cent zinc and 32.9 per cent antimony (Minister of Mines Annual Report 1942, page 32). This sample may be from the Point (103F 002).

This prospect has been explored intermittently since its discovery in 1942 by Victor Courte and Robert Mickle. Quintana Minerals Corp. completed geochemical and geological surveys in 1974. JMT Services Corp. and Chevron Canada Ltd. conducted geological and geochemical surveys in 1978, followed by the drilling of nine holes in 1979 to 1981. Umex Ltd. located claims over the eastern end of the prospect and by 1981 completed geological, geochemical and airborne geophysical surveys. Six short holes were also drilled by the company in 1981. Noranda Exploration Co. Ltd., Umex Ltd. and Noramex Minerals Inc. conducted geological, geochemical and ground geophysical surveys in 1985 and 1986, followed by the drilling of two diamond drill holes totalling 682 metres in 1986. Misty Mountain Gold Ltd. completed airborne, radiometrics, resistivity, magnetometer surveys over the prospect in 1995, while exploring a large block of claims surrounding the Sol property.
