1953 AEC REPORT <br />occurs in secondary barite that contains native silver, and <br />with incrustations of goslarite [a hydrous zinc sulfate]. <br />General discussion of Aspen geology derived from previous <br />authors,°1 pp. 5-13. <br />The Smuggler Mine, pp. 13-20 <br />Historv and Production, pp. 13-14. The principal Smuggler <br />workings were begun about 1884 and [the lower workings] were <br />allowed to flood in 1918 following a dispute over power <br />rates.'Z At the time pumping ceased, up to 3,500 gallons per <br />minute were being pumped up three shafts. Minor production <br />by lessees continued from 1918 to 1941. The Herron brothers <br />operated a small gravity concentration mill with selected <br />ores from the Smuggler and Mollie Gibson dumps, and <br />conducted exploratory work in the Smuggler No. 2 tunnel. <br />The U.S. Bureau of Mines conducted sampling and drilling <br />studies targeting lead and zinc in 1946, 1947 and 1948 in <br />the No. 1 and No. 2 tunnels. The Anaconda Mining Company <br />did considerable rehabilitation and exploration work in 1949 <br />and 1950. The Herron Brothers resumed milling and <br />exploratory work in 1952. The Smuggler produced <br />$20,000,0000 in Pb, Ag, and Zn up to 1918." Extraordinary <br />amounts of free silver were produced. <br />Mine Workings, p. 14. Approximately 2,500 ft. of Smuggler <br />workings were above water level, in the No. 1 and No. 2 <br />tunnels [and associated workings], with the water level 20 <br />ft. below the No. 1 tunnel." There were nearly 75,000 ft. <br />`1 J. E. SPURR, GEOLOGY OF THE ASPEN MINING DISTRICT, COLORADO, U.S. GEOLOGICAL <br />SURVEY MONOGRAPH 31 (1898)("SPURR MONOGRAPtl")~ SPURR REYORT~ A.
