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 Sunshine showings occur 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 a stockwork of fine quartz veins. These veins occur in a carbonate alteration zone surrounding ultrabasic dikes. Mercury mineralization also occurs in carbonate altered andesite and schist as disseminations.

In 2001, Doublestar Resources Ltd. and Murray Morrison completed an exploration program on the Mur property containing the occurrence. Mapping was completed but no notable mineralization was observed.

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. Rock samples graded up to 0.24 per cent nickel in the area immediately surrounding the occurrence (Assessment Report 32715).

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.
