The Cooper property is located between the headwaters of Kamma Creek, which drains into the Goat River, and the South Moyie Creek, which drains into the Moyie River. The claim area is south of and along strike from a regional fault underlying Perry Creek, where lode gold mineralization has been found; exploratory and active placer gold operations are present along the Goat and Moyie rivers respectively. Gold has been found in individual quartz veins (2-20 metres wide), mineralized shear zones associated with Middle Proterozoic Moyie intrusions, and altered zones surrounding syenite intrusive bodies located along major faults.

The property is underlain by rocks of the Creston and Aldridge formations, comprising respectively shallow water sedimentary and deeper water turbidite facies; siltstone, argillite and fine- grained quartzite are represented. These strata have an average strike of 215 degrees and dip 40-85 degrees west; there are a number of medium to small sized shear or fault zones throughout the property that strike northeast and dip vertically.

Pyrite is associated with small quartz veins up to 0.5 metre thick within the Aldridge Formation, occurring as single cubes and fine disseminations throughout the veins; specular hematite is also associated with small quartz veins.

Pyrrhotite occurs as fine blebs in Aldridge argillaceous quartzite float, and there is also abundant float of milky white quartz ranging up to large 5 metre angular boulders of quartz vein float that suggest a local source.

Anomalous gold up to 670 parts per billion was found in bulk stream sediment samples draining east off the property but follow-up soils were not able to pinpoint the source of the gold; anomalous gold was found to 180 parts per billion in a five metre quartz vein which contains hematite and chlorite. This sample also contains anomalous copper (100 parts per million) and arsenic (177 parts per million) (Assessment Report 19436).

In 1989, Placer Dome Inc. completed a program of geochemical and geological surveys on the Cooper 1 to 4 claims. In 1994, sampling returned very anomalous gold values, up to 1,460 parts per million; drilling the same year failed to intersect any mineralization (Assessment Report 29961). In 2006 through 2008, the area was explored as the Faith property Dynamic Exploration Ltd.
