| Comments | Discovered in 1970s, mapping and geochemical surveys, partly drilled (5 holes). Modern exploration defined two targets within a thrust zone: (1) Basalt prospect, thrust-related copper in basalt, and (2) Breccia prospect, porphyry-style copper mineralization in diorite below the thrust. Breccia prospect drill intercept example: ~155 m of 0.19% Cu and 0.03 g/t Au. |
