According to the USGS, the Caledonia was first discovered in 1859. The first year of real production was 1871. Silver and gold were listed as primary commodities. USGS Report Quote: "Caledonia claim resulted from consolidation of seven claims in 1866- Ore was found and work continued until 1873. Continued exploration revealed scattered bodies of low-grade ore through the late 1890's. Some good ore ($91/ton) was found in 1902, but most production through the early 1900's was from relatively low-grade ore. Currently off south end of Houston Oil and Minerals open pit mining operation." The 1860's consolidation of these claims was done by the Caledonia Tunnel Company.
