A number of mercury showings occur along the Pinchi Fault zone. The Pinchi Fault separates the Mississippian to Triassic Cache Creek Group from the Upper Triassic Takla Group. The fault has provided zones of permeability for the passage of mercury-bearing hydrothermal solutions in a number of places along its length. The origin of the mercury mineralization is not yet clear and in many places there are no obvious sources of heat or origin of the metals.

The Cin showing occurs adjacent to the Pinchi Fault. The area is underlain mainly by metamorphosed sedimentary and volcanic rocks of the Mississippian to Triassic Cache Creek Group. Cinnabar mineralization occurs in siliceous re-cemented breccias of limestone, dolostone and chert.

In 1965, The Consolidated Mining and Smelting Company of Canada Limited completed a geochemical survey on the north-central shoreline of Pinchi Lake. Mercury soil anomalies were observed in the area of the occurrence.

In 2011, Nanton Nickel Corporation completed an exploration program including an airborne helicopter geophysical survey, reconnaissance mapping, prospecting and geochemical sampling over the property containing the occurrence. Four major, magnetic high anomalies were noted on the property. Sampling was completed on an area 1 to 3 kilometres north of the occurrence.

In 2012, Nanton Nickel Corporation completed an exploration program including ground mapping, prospecting, soil and rock geochemical sampling and a petrographic study. Rock and soil sampling was not completed on the area immediately surrounding the occurrence.
