History:
1898-1903: Two adits; vertical 3 compartment shaft to 420 feet; levels at 100, 200, 300; 606 feet of lateral development on surface from 100 foot level. 1899-1903: Production 1 524 000 lbs. copper from 43 300 tons of ore, by Rock Lake Mining Co. Ltd.
1950: 3204 feet d.d. by East Sullivan Mines Ltd.

Geology:

A stockwork of discontinuous quartz-carbonate-chalcopyrite veins in a fault zone, which strikes N55W and dips 90 to 70 N, has an average width of 50 to 100 feet. It has been traced by drilling for a strike length of 1000 feet and by surface prospecting for a length of 2 miles.
