Sep 12, 2016 (A Wilson) - The dike has an exposed width of about 100 ft. Its continuation from the pit along the strike is obscured by a rather heavy dirt cover, which entails considerable stripping. Numerous small, narrow pegmatites outcrop as hogsbacks protruding through the overburden in the supposed general area of the McDonald Showing. Mineralogically, they are all very similar, containing abundant graphic K-feldspar and quartz intergrowths, biotite, tourmaline and pyrite.

Sep 12, 2016 (A Wilson) - The dike consists of pink spar, carrying stringer of buff-coloured spar and quartz. Black mica in large thin plates is fairly abundant and there is also considerable tourmaline in thin needles. While a large proportion of the mine output has consisted of a mixed grade of spar, recent work has shown the quality to be improving at the west end of the pit. The west face in 1932 showed a 40 foot width of high-grade, buff, crystal spar, extending almost from the surface to the floor of the pit. The heavy capping of pegmatite carrying black mica that covered the easterly section, thins towards the west, and a high percentage of the rock broken since 1931 now consists of merchantable spar.
