There is one locomotive and eleven bottom dump cars, one barge, one tow boat, one air compressor, two Sullivan air drills, one No. 3 gyratory crusher, one 12-foot screen, drill tools, etc. The buildings consist of a cookhouse, blacksmith shop, powder house and several small buildings. Electricity is purchased at 2 cents per kilowatt hour. The capacity is 400 tons per ten hours. The rock is hauled by rail one mile to the bay and loaded on barges and towed to Eureka. The specific gravity of the rock is 3.169 and contains 42.7 per cent silica. The rock is used for road metal and for filling."
