Mine Description

The Cumberland, is described by Lindgren as follows: "The Cumberland mine is one mile north of Pine Flat and was last in operation about 1908. According to information obtained from T. Roach, of Pine Flat, this is a gold quartz vein striking a little east of north and dipping west. The shaft is 350 feet deep and there are short drifts. The shoot on the north is said to have continued to the lowest workings; it contains ore of $40 grade, which was treated in a 10-stamp mill at Pine Flat. The gold is reported as free and visible in places. The water level was found at a depth of 90 feet."

“It is probable that here, as in many other places, the conditions became unfavorable when the workings reached the Sulphide ore below water level. There is said to be placer ground in the vicinity of the Cumberland mine.”
