The Dad occurrence, located to the south of the eastern end of Pinchi Lake, occurs adjacent to the Pinchi Fault. Here, the Upper Triassic Takla Group rocks are in contact with supracrustal rocks of the Mississippian to Triassic Cache Creek Group and ultramafics of the pre-Middle Triassic Trembleur Intrusives.

The showing is not well described; mercury mineralization is reported to occur in a harzburgite-gabbro-greenstone sequence which is probably a sequence of Trembleur and Cache Creek Group rocks. The sequence is faulted by a northwest-trending fault system which forms the southwest margin of the Pinchi Fault zone.

In 1965, The Consolidated Mining and Smelting Company of Canada Limited completed a geochemical survey on the Merc property near the occurrence. Mercury anomalies in the soil samples were noted.

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 from the area yielded up to approximately 0.2 per cent nickel (Haslinger, R.J. (2015-01-28): Technical Report on the Murray Ridge Property).
