The Harris Mine, just to the southeast of the Allen Mine, opened in 1942. A 50-foot diameter, 15 foot deep circular pit was excavated and later extended as mining continued through 1942-1943 and again from 1945-1946. The average grade ore from the Harris Mine was measured at 58.0 percent aluminum oxide (Warren and others, 1965).
