| General | "The occurrence of quicksilver in the prospect of A.G. Lewis, about half a mile north of Boulder station on the Great Northern Railway and 300 feet from the track, is mentioned in Mineral Resources for 1917, page 415. At that locality several fissures that traverse granitic rock contain chalcedonic quartz. Pits on one of these veins show earthy cinnabar coating fragments of the vein material. This particular vein is about 1 foot wide." (Bull. 842, p. 293-294.) |
