Gold Rush Show amatuer dryland dredge experiment
« on: March 03, 2017, 01:50:45 PM »
I noticed on the Gold Rush Show that most of the crews scape down to bedrock with big blade equipment. Do you think a dryland suction dredge operation could scavenge the good gold remaining after they do their removal?

Create or use a small pond, use a dryland suction nozzle and small trommel/sluice combo and take all the remaining gold-Any thoughts?

Depends on the type of bedrock you encounter and the skills of the excavator operator. We dig 2 to 10 feet into the bedrock. All bedrock has to be dry and must use a scraping bucket.

It's mostly a yardage game. In the Yukon people go by the saying 100 yards/1 ounce Most plants run by one guy process 100-200 yards an hour. If the material is 100/5 ounces and more and the digging crew messed up the cleaning job,  a dredge can be profitable but with a dredge you only move one or two bucket of dirt per hour. So its like going sniping in creek with a pair of tweezers.

I made the second picture for the old man but that gives an idea how big is the ground.

Oh and wages,food, room and fuel each worker may cost 1-2 ounces of gold per day depending on the machine he runs and the purity of the local creek gold.

It would be a fun try. A quick test of an area would yield some answers.  A 1-2 oz/day would seem to justify expenses. I've been to this area and the gold is 20-30 feet deep. If the guys have removed all they want a small quick operation could possibly work out. The old original guys worked every layer to get it all.

The equipment used in hydro excavation has improved greatly in the last few years. They would clean up bedrock.

There must be some enterprising sourdoughs in Dawson City that could provide their fine services fora percentage on a fixed clam.. After all, the ground is ready and the gold has certainly settled during the excavation process. Only a real on ground test would determine the cost/benefit (PROFIT) of this hydro excavation recovery system.

If it exists, any details on the following:  how large is the equipment, portability,area/day covered, yields and size of gold recovered.
