The Old Yeller showing is located about 2 kilometres east-northeast of the village of Moyie, a little north of Glencairn Creek.

The Old Yeller area is underlain by quartzites, siltstones and argillites of the Helikian Creston Formation (Purcell Supergroup). The area is transected by several important base metal-bearing structures (St. Eugene (082GSW025), North Break, Old Yeller (082GSW111), etc.) but much of the area is masked by overburden.

In 2011 and 2013, Kootenay Silver completed programs of geological mapping, rock sampling, a 500-line-kilometre airborne magnetic survey and a 500-line-kilometre seismic survey on the area known as the Silver Fox property. Work revealed target 1 which later in 2013 was referred to as Old Yeller. Samples were collected from an old pit dump characterized by yellow stain, limonite and quartz breccia. Sample analysis revealed highly anomalous lead, antimony, zinc, and copper. Sample MK13-119 graded greater than 1 per cent lead and 0.095 per cent zinc (Assessment Report 34695).

In 2018, a program consisting of geological mapping/prospecting and pXRF soil sampling was completed along the basal member of the Middle Creston Formation for approximately 17 kilometres from north of Barkshanty Creek to south of the headwaters of Teepee Creek (Assessment Report 38925). The work area covered Society Girl (082GSW030) and Golden Burp (082GSW085) with St. Eugene (082GSW025) and North Zone (082GSW086) being a little further west. Scattered copper mineralization was documented at various locations in the Barkshanty map area. Two holes were drilled on the property immediately between Barkshanty and Glencairn creeks, about 3 kilometres east-northeast of Moyie and 1 kilometre east of Old Yeller. The first hole was abandoned at 135 metres due to a rig breakdown. A second shallower hole was drilled from the same location, ending at 500 meters. The purpose of the program was to test the basal member of the Middle Creston Formation for stratabound copper-silver mineralization.
