platinum was discovered in the bass mine in 1914, but production of this element never fulfilled any of the expectations its discovery generated (hewett, 1931, p. 69-71). gold is chiefly a byproduct of zinc-lead-silver ore. from 1902 through 1959 a total of 58,815 ounces of gold was produced none of
some gold in the breckenridge district has also been derived as a byproduct from silver-lead-zinc ore, chiefly from the wellington mine, which became an important producer in 1910 (lovering, 1934, p. 3). this mine operated continuously to 1929 and sporadically thereafter until 1958. lode mines in the district were virtually inactive in 1959.
the ore deposits are diverse and have yielded copper, lead, zinc, silver, gold, iron, manganese, and molybdenum. total gold production of the county through 1959 was about 501,000 ounces. before 1900 placers and oxidized ores were the chief sources of the gold, but from 1912 through 1959 much gold has been a byproduct of base-metal mining.
