Could this be our Baltimore Mine?

The Baltimore mine (MS# 1540) is located in section 7, T6N R4W on the east slope of Boomerang Creek canyon about four miles northwest of Boulder. The Baltimore was the district's largest and most consistent producer; it was active 38 of the 50 years between 1903 and 1953. In 1903 the mine was reported to be making regular shipments of ore to the smelters and was leased for $20,000. In 1906 the mine was worked by Moore and Gendle. The next year it was reported that an eighteenth interest in the mine sold for $10,000. In 1914, lessees reported shipping a sulphide ore that carried $2.00 in gold and 25 ounces of silver per ton along with 7 percent lead and 2 percent copper. The mine continued to be worked intermittently by lessees. In 1933 the mine was sold by Peter McDermott to Wallace, Idaho operators.

The mine was developed out of at least six adits and in 1907, it was worked through a 140 foot shaft and had 2,000 feet of workings. When visited by Knopf in 1911, the mine was being worked from the lowest adit. The next year, the mine was leased by Charles Whitcomb & J. H. Mulligan who employed 60 men extending the mine 600 feet and extracting ore. Two adits were listed at 500 and 600 feet. In 1935 the mine listed four adits which ranged from 300 to 750 feet in length; the underground workings were estimated at 3,000 feet of drifts and crosscuts within a zone of 1,000 feet horizontally and 300 feet vertically. The mine was cut through aplite in quartz monzonite to reach short irregular veins with numerous branches. The branches could swell up to six to eight feet in width. In 1918, when the mine was mapped, two groups of veins were represented. Ore in the veins consisted of pyrite with sphalerite, galena and chalcopyrite (Knopf 1913; Gilbert 1935; Roby et al. 1960).

The mine produced 18,148 tons of ore which yielded 1,734 ounces of gold; 275,489 ounces of silver; 271,266 pounds of copper; 1,263,965 pounds of lead and 280,750 pounds of zinc (Roby et al. 1960).
