EXPLORATION AND DEVELOPMENT
1908: Spectacular silver ore was discovered on surface. Shaft No.l was sunk 115'on a lens of high grade silver ore which ended at 25' depth. Short drifts were made on the 30' level; on 100' level crosscuts were developed for 135'N and 135'S. No.2 shaft (1000' SW of No.l) was sunk 110' with 230' of crosscutting on 100' level. SW of No.l shaft open cuts were made on a vein (strike S52°W)for 350'.
1917-19; No.l shaft was deepened to 300' with 1000' of workings on 30', 100', 200' and 300'.
GEOLOGY
Nipissing quartz diabase occurs as topographic ridges
running N-S a little W of south part of Gowganda lake; the diabas
Is arched to dip E and W under flat lying Cobalt Series conglomer
ate and quartzite but centrally overlies Lorrain Quartzite. The
diabase locally shows alteration to granophyre (aplite) and is
often much fractured. Locally scales of silver enrich the
diabase over inches to feet in width. Massive ore occurs as
silver and smaltite in narrow calcite veins, with minor argentite
niccolite and chalcopyrite, and also disseminated magnetite.
