Below is a series of photos showing Doug Clark's Ganes Creek Placer mining.
The overburden is removed and the gold bearing gravel is pushed into a pile by a bulldozer.
In the first photo is the sluice fed from a backhoe. There is a water pipe bringing water from a stream using a large pump. There is a conveyer belt moving the larger rocks out to the left. On that belt is a metal detector which would shut down the operation if it sensed a large metal object, like a large gold nugget. Below the conveyer belt is the dirty water coming out of the sluice. It flows into a holding pond. It is just like a large high-banker machine that we have all used, but larger and better.
The second photo is step one of the cleanup. Take the metal riffles out. Next the concentrate under the riffles is scooped out and then the miners mat is rolled up to be taken and washed.
The floor of the sluice is scooped clean and washed down.
One photo shows the concentrte with gold nuggets, like raisin in a pie.
The metal riffles have holes in the bottom and high pressue water is always comming out to keep the concentrate loose and able to hold more gold. The water holes have to be cleaned.
That is about it, the sluice is then set up and run again. The concentrate is taken back to camp and cleaned more in a small tumbling mill and sluice.
I think Doug said that thy got about 30 Troy OZ. on this cleanup. Most of the gold is small. Largest nuggets were thumbnale size.
Hang in there with me if I do not attach all seven photos. I will enter the missed ones (if that happens) later.
