Surface and underground work (pits, trenches, tunnels) were completed between 1928 and 1930 on the Copper Cup, Copper Chief (082LNW019) and Vimy (082LNW020) showings. The Copper Chief adjoined the Copper Cup to the east, and the Vimy adjoined the Copper Cup to the southeast.
At the Vimy showing, silicified zones traverse west striking, north dipping (35 degrees) chlorite schist of the Devonian and/or older? Woolford Creek unit of the Eagle Bay assemblage. These zones contain small bodies of chalcopyrite and pyrite associated with quartz seams which cut the hostrock obliquely.
A sample taken from some of the best ore assayed 0.34 gram per tonne gold, 13.7 grams per tonne silver and 14.4 per cent copper (Minister of Mines Annual Report 1928, page C211).
