Nictaux Falls Dam
The Nictaux Falls Dam property sits in the Meguma terrane of northwestern Nova Scotia. The oldest rocks on the property are the Lower Ordovician Halifax Formation cut by several basic sills and dykes. The formation is conformably overlain by the Ordovician-Silurian White Rock Formation, composed of thinly interlaminated silty slate and quartzites, interbedded volcanics, quartz arenites. It is in turn covered by the Lower Devonian Torbrook Formation made of fine grained gray pelitic rocks. The Nictaux Property contains polymetallic (Co-Ni-As-Bi-Au) sulphide-bearing quartz veins and stockwerks hosted by the Ordovician-Silurian White Rock Fm. The veins are exposed in the spillway of the Nova Scotia Nictaux Falls Power Dam, in the southern margin of the Annapolis Valley. They contain arsenopyrite, cobaltite, pyrite, chalcopyrite and native gold. The Ordovician-Silurian formations are cut by granitoid rocks of the Devonian South Mountain Batholith. Sampling by a government geologist in 1992 returned concentrations of up to 1.6% Co, 0.28% Ni, 88ppm Bi and 776.11 g/t Au from the main showing.
