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 Mount Pinchi showing consists of specks of cinnabar in carbonatized and silicified schist of the Mississippian to Triassic Cache Creek Group. This alteration zone is probably related to a branch of the Pinchi Fault.

In 2011 and 2012, Nanton Nickel Corp. completed programs of reconnaissance mapping, prospecting, geochemical (rock, stream sediment and soil) sampling and a 1055 line-kilometre airborne magnetic survey on the area as the Murray Ridge property. In 2012, rock samples taken from an area approximately 2.5 kilometres to the north yielded up to approximately 0.2 per cent nickel (Haslinger, R.J. (2015-01-28): Technical Report on the Murray Ridge Property).
