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 noticeable wear and fraying at the mouth. It has a heavily faded horizontal blue stripe and the text "NEW COSO / MINING CO / KEELER CA" printed in black ink (heavily faded; "KEELER CA" is totally illegible). As color coding was used by some mining companies to indicate grade of ore, this blue stripe may have served a practical purpose. Reverse side has large, handwritten text reading 'B4', likely marking the origin of the contents. It also has the words "DARWIN DEV. CORP" printed in black, added after the mines' acquisition in 1915.
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 Corp. 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.
