The Bear South occurrence is located on the north side of Milefive Lake, near the Likely Road.

The area is underlain by marine sedimentary and volcanic rock units of the Permian to Triassic Cache Creek Complex. These are composed of undivided phyllite, siliceous phyllite, ribbon and massive chert, argillite, tuff, mafic volcanic rocks, serpentinite, limestone, and sandstone. Limestone, marble and calcareous sedimentary rocks of the Marble Canyon Formation occur as a narrow, northwest- trending unit transecting the western portion of the area.

Locally, nickel mineralization is associated with serpentinized ultramafic rocks that may or may not contain magnetite. The serpentinite often contains irregularly folded veins of calcite-dolomite up to 5 centimetres thick. In 2014, two rock samples (Q345536 and Q345522) assayed 0.097 and 0.147 per cent chromium, respectively, with 0.224 per cent nickel (Assessment Report 35257).

In 2014, Westhaven Ventures completed a program of rock sampling, prospecting and 529 line-kilometres of airborne magnetic and radiometric surveys on the area as the Ben South property.
