The Mirror Ball 1-4 claims are located on the north side of Lupin Lakes. The claims were staked in 2000 and the next year a program of prospecting and geological mapping was performed. Through prospecting, three favourable areas of interest were identified for the production of decorative rock. Two of these are proposed for future quarry locations.
The area is underlain by Jurassic rocks of gabbro, hornblende diorites and pyroxenites, roofed by granitic rocks from the central portion of the Thuya batholith. To the south, within the contact is Pennsylvanian Harper Ranch assemblage; there are also phyllites and turbititic sequences of limestones and argillaceous sediments.
Locally, massive pyroxenites that were clean of impurities such as sulphides, oxides, alkalis and calcite, and having an attractive appearance for decorative rock occur. The core area appears to be a series of sequences of dikes the range from 5 to 75 metres wide and is irregular in distribution. The pyroxenite is medium to coarse grained, with clinopyroxene and orthopyroxene as the main components with the exception of olivine in some localities occupying 30 per cent of the whole. Block jointing is variable, 1.0 by 1.6 metres up to 1.4 by 1.7 metres, with the outer core near the contact less than 0.5 by 1.0 metres (Assessment Report 26770).
