Figure 3. Plots of As vs Bi (A), Cu (B), and Sb (C) showing
positive correlations between these elements. These elements
may be found together within copper-containing veins
of future exploration and production. Future work will
involve targeted sampling of ultramafic rocks in the district
to assess the potential for PGE, as well as characterizing
copper-containing veins to determine mineral phases that
host As, Bi, and Sb.

that drain more mafic or ultramafic lithologies (e.g.
hornblendite and hornblende gneiss) generally contain more
MgO than felsic lithologies such as the granites and aplites
