An antique ore bag from the New Coso Mining Company of Keeler, California, dating from c.1870s-1880s. The bag has a coarse weave with some wear and fraying at the mouth. It has a vertical blue stripe running up the side of the bag as well as the text "NEW COSO / MINING CO. / KEELER CA" printed in red ink (heavily faded, 'NEW COSO' is legible). As color coding was used by some mining companies to indicate grade of ore, the blue stripe may have served a practical purpose.
New Coso owned the Lucky Jim and Christmas Gift mines near Darwin, California, two silver mines that began operation in the 1870s, were consolidated by Darwin Development Co. in 1915, and were eventually bought and operated by Anaconda Mining Co. in 1945. Darwin was the smelter site for New Coso; the resulting products would then be shipped to Keeler, where they would be transported via the Carson & Colorado Railroad. The company's workings were 500' deep by 1884, and they had produced up to $1.5 million of rich ore by 1888.
From the Palazzo collection.
