The Goldbreak 12 occurrence is located in the southern headwaters of a south-flowing tributary of the French River, approximately 3.2 kilometres northeast of the north end of Gallic Lake.
Regionally, the area is underlain by limestone, marble and calcareous sedimentary rocks of the Rosella Formation and quartzite and quartz arenite sedimentary rocks of the Boya Formation, both of the Lower Cambrian Atan Group.
Locally, a brecciated quartzite and/or chert hosts chalcocite with minor arsenopyrite, chalcopyrite and native copper. Goethite, calcite, malachite and sericite are also associated with the mineralization.
Work History
In 1985, Claimer Resources Inc. completed a program of prospecting, geological mapping, rock sampling and ground and airborne geophysical (magnetic and electromagnetic) surveys on the area as the Goldbreak 12 claim. A rock sample (G12CR22) assayed 2.34 per cent copper (Assessment Report 15388).
