EXPLORATION AND DEVELOPMENT
1908: High grade silver ore discovered on outcrop.
1910-1920: A series of open cuts were made on high grade silver ore shoots along a mineralized zone of 700' in length. Several shafts were sunk; the main shaft to 200'. Levels were developed from the 50' to the 200' one.
1966-68: Diamond drilling and trenching was carried out In the area. Several narrow NNW striking veins assaying 10.5 ozs./ton sliver were found between Reeve and Dobie lakes.
GEOLOGY
Nipissing quartz diabase occurs as topographic ridges running N-S a little W of south part of Gowganda lake; the diabase is arched to dip E and W under flat lying Cobalt Series conglomerate and quartzite but centrally overlies Lorrain quartzite. North of the property a strong fault strikes N-S and dips 45°W; within the property several strong faults occur. The diabase locally
shows alteration to granophyre and is generally much fractured.
Numerous veins strike NE, N, NW and E-W and locally contain short
but rich ore shoots.
