The 41 Mile Creek occurrence is located approximately 1300 metres upstream from the junction of Corral Creek with Whipsaw Creek, just above the confluence with its principal south-flowing tributary.

The region at the headwaters of Whipsaw Creek is underlain to the west by intrusive and metamorphic rocks of the Late Jurassic to Early Cretaceous Eagle Plutonic Complex and to the east by metamorphosed volcanics and sediments of the Upper Triassic Nicola Group. The contact between the two units trends north-northwest.

Locally, a 0.17 to 0.30 metre quartz vein, striking north 20 degrees east, hosts galena, sphalerite and pyrite mineralization. In 1979, a 13 centimetre wide chip sample yielded 6.86 grams per tonne gold, 340.1 grams per tonne silver, 0.694 per cent copper, 11.4 per cent zinc and 19.3 per cent lead (Assessment Report 8005).

The area has been explored in conjunction with the nearby Whipsaw (MINFILE 092HSE102) occurrence since the late 1950’s. Various operators, including Texas Gulf Sulfur Company Ltd. conducted geophysical, geological and soil surveys and trenching between 1959 and 1981. The area was more recently explored by World Wide Minerals Ltd., with the completion of geological mapping and soil surveys between 1987 and 1993. During 1995 through 1998, Martech Industries completed 10 diamond drill holes, totalling 1033.5 metres, on various targets over the Whipsaw property. In 2000, a pulp sampling program was completed to test for platinum group elements from former trenching and drilling programs but results were disappointing. In 2005, Canfleur Mining completed a program of sampling and seven diamond drill holes, totalling 1452.8 metres, on the area. During 2010 through 2015, Martech Industries completed programs of rock and soil sampling.
