When I revisited the mine in 2013, the hoists were scrapped and sitting by the road.
Tucked-into the side of the concentration mill… these machines were meant to crush underground rock into a fine dust for mineral extraction.
Part of the grain dust venting system, dislodged from its place above the dumping hatches under the grain cribs.
Kate for scale. Powder that passed the floatation level was flowed over sluice tables, another mass-based way of separating gold. I’ve never seen so many of these in one place. Though it was a hardrock mine, it worked more like a placer mine.
The steam-powered hoist that pulled ore and dropped men from the mine. Note the hydraulic-operated brake on top with its massive brake pad. Now scrapped.
A colorful boiler is a happy boiler! RotoGrate systems remove ashes from the boiler firebox by revolving the bottom of the system to let the fly ash drop into a hopper. This greatly increases boiler efficiency.
Gold, which has a relatively high mass, would drop through the slats of the sluice boxes as the water flowed over them. Around the dredge were a half dozen radiator pipes to keep the water flowing through the machines.
Away from the rest of the plant–as if forgotten, or hiding–is this little stamp press. Yes, this is little by press standards.
