United States Department of the Interior, Geoloical Survey Bulletin 922-Q, 1941, p. 510 : The Lucky Strike Mine is on the south side of Deep Canyon, several thousand feet west of the Little Sister Mine. It is developed by two adits 90 and 135 feet below the outcrop and by a glory hole. The ore body, which dips gently southeastward, is a single bed of tactite 10 to 20 feet thick. Ore does not continue to the lower adit although the tactite persists. At the surface the same ore bed appears along the strike to the southwest in several prospects separated by bodies of quartz diorite. These prospects may still contain some ore.

At the surface the hanging wall of the ore body consists of thick beds of marble, which is bordered comfortably by quartzite and schist bands along the ridge to the southeast. The footwall is partly silicated limestone. The large mass of marble, which contains no tactite or scheelite, is cut off by quartz diorite along the strike in both directions.
