Echo, Echo....Hello down there Kurt Bloomberg resident of the permofrosted gold gravels of Vault Creek just North of Fairbanks , Alaska. Kurt is currently opening an old prospect on the head waters of Vault Ck. on Vault just above the confluence of Vault and Babe Ck. A Doug sharier is his mining partner.
This shaft is currently down to 25 feet which is shallow compared to their 80 foot 6' by 6' over at their base camp on Babe Ck..

The generators (below) power an electric chisel/ jack hammer and of course provide the lighting for the extended depths. The topside portal was recribbed .

Why reopen the prospect? Well Kurt and his wife earlier in the summer reprocessed some of the old tailings next to the pit with Kurt's newly design trommel. The gold retrieved in the surface test has fueled this reopening. thumbs up cool!

Hey, Bill
Much appreciate the report, pics and video as well as your help up top dumping the ice bucket. It has taken 5 days to recover from all that ice hoisting, but I'm missing it already and can't wait till spring to go the final few feet to bed rock and then begin steaming the gravel.

Kurt,

Doug operated in the winter at Boob Creek. Do you guys have plans for winter drift mining?

Please tell drift_miner and Gail hello for me.

Geowhiz,
Doug is back in Fairbanks and will be heading out to Babe camp soon, I suspect. What his plans for continuing in the big shaft are, I don't know. My little shaft will have to sit idle till spring unless something extremely tempting comes up and I head back up there for few weeks this winter.

looks like fun but lots of hard work.

From the photos, I would put the generators at least 20-30 feet away from the shaft. Carbon monoxide will sink down the shaft with bad results.

Kurt..
How did your trommel work out? What speed are you turning that small drum at? Would you do anything different on it now?
Sure a slick little set-up.

Dick,
The Eureka Gold Thief worked like a charm. Running the engine at about 1600 rpm the barrel does around 30 rpm. I was extremely pleased with the performance of the riffle design which caught, as best as I can determine, virtually all the gold. We panned the tailing fines out of the "boil bowl" and found nothing to speak of. That particular machine was a rebuild of my first Gold Thief. I'll be coming out with a new model that is stronger, lighter, easier to assemble and disassemble, easier to feed and less expensive. It will also have more wash area [less perforated area], larger hopper, smaller, more fuel efficient engine [the current 4.5 hp Briggs is too overpowered] and probably a slightly longer, side discharge sluice box. Hope to have a working unit by mid winter.

Miner Mike,
That's a great observation. I'll make sure I keep the generator far enough away from the shaft next spring.

Hey, Bill,
I've been meaning to ask Allan about what he recovered from the few shovels of pay he washed. Looks like I have my answer. He was curious about the silver or white heavies in the sample. Any idea what they are?

Probably replicates the stanford mine stibnite. Go to mindat.org and see if you can obtain the model from your neighbors block. I think there is a write up on it.
Nice gold by the way :)
