The Wheaton Lime occurrence is located about 5 kilometres east of Turnagain Lake, 55 kilometres east-southeast of the community of Dease Lake.

The showing area covers Upper Triassic Sinwa Formation (Stuhini Group) limestone exposed in the core of an anticline in an inlier surrounded by phyllitic slate and pebble conglomerate of the Lower Jurassic Inklin Formation (Laberge Group). Exploration concentrated on sections of the Sinwa Formation limestone exposed in several well-incised creeks, located immediately north of Settea Creek in the western portion of the property, and in the headwaters of Wheaton Creek in the eastern portion of the property.

The limestone is a light grey weathering, medium to dark grey on fresh surface, fetid and crystalline to fossiliferous. In several of the larger exposures, located north of Settea Creek, beds of massive, oolitic and fossiliferous limestone 20-500 centimetres thick are separated by platy-weathering beds 10-20 centimetres thick. Pelecypod shell fragments to 10 centimetres in length are the most abundant fossils. Bedding in this area strikes approximately 115 degrees with dips either vertical or steeply to the north.

Sinwa Formation limestone is exposed in the core of a broad anticline in the headwaters of Wheaton Creek, in the southeastern portion of the property. Several large limestone outcrops are cut by anastomosing white quartz veins generally 2-8 centimetres thick, but occasionally 30 centimetres, and quartz lenses up to 2 metres in size. Thickness of the Sinwa Formation was not determined since the base is not exposed on the claims.

In 2010, a rock sample (178469) of limestone analyzed 56.17 per cent calcium oxide (Assessment Report 32016).

In 2010, Hard Creek Nickel Corp. collected 14 samples for whole rock analysis in an attempt to locate a local source of metallurgical limestone for the Turnagain nickel sulphide deposit (104I 119) located 21.5 kilometres north-northeast. Limestone samples were collected and analyzed to investigate their suitability as a pH control in a metallurgical facility.
