The High Grade occurrence is located at an elevation of approximately 1520 metres on a northwest trending ridge separating McPhee Creek to the north and Champion Creek to the south.

Regionally, the area is underlain by granite and granodiorite of the Late to Middle Jurassic Nelson Intrusions and small areas of volcanic rocks of the Lower Jurassic Elise Formation (Rossland Group).

Locally, a 35 to 50-centimetre wide zone of alteration and narrow quartz vein trends approximately 330 degrees and dips vertically in a fresh intrusive.

In 1999, a sample is reported to have assayed 708 grams per tonne gold (Dandy, L. (2018-05-25): Technical Report on the Cobalt Hill Property).

In 2010, two samples (AG-009 and -010) assayed 380 and 53.9 grams per tonne gold with 27.8 and 72.6 grams per tonne silver, respectively (Assessment Report 31929).

Work History

The property was acquired in 1981 by Pearson, Gallagher Ltd., of Nelson. Bruce Doyle acquired claims in the area about 1995; these were optioned by Phelps Dodge Corporation of Canada in 1996. They carried out exploration, including soil geochemical sampling, mapping and prospecting on the south-central part of the property in 1997. The option was dropped in 1997. Interest in the property is being acquired by Miner River Resources Ltd. and Eagle Plains Resources Ltd. Interest in the property was acquired by Eagle Plains Resources Ltd., the next year. Cassidy Gold optioned the property in September 2000 and completed a small diamond drill program including five holes, totalling 607 metres. Three holes were completed on the High Grade occurrence. Firestone ventures optioned the property in 2004 and in 2005 completed a program of prospecting, rock and soil sampling and geological mapping. In 2007 and 2008, Medallion Resources examined the property and completed a helicopter-borne mag-AeroTEM-radiometric survey and soil sampling. During 2009 through 2011, Cassidy Gold and Swift Minerals completed programs of prospecting, soil sampling, geological mapping, three diamond drill holes, totalling 147 metes, and 147 metres of trenching on the area. During 2012 through 2018, the area was prospected by B. Doyle. Later in 2018, Walcott Resources Ltd. completed a program of ground geophysical surveys on the area as the Cobalt Hill property.
