    Life At The Bottom Of A 64' Shaft

    It's almost summer, though it still doesn't feel like it. I prepared well for spring run off by removing snow from all around the shaft area, tons and tons of snow and all by hand. It was good to get my body ready for mucking pay. I've had reasonable success thawing gravel with my heat rods and I'm getting more efficient with the drilling apparatus. But just when things were clicking along, my generator died on me mid way in a thaw. I tried repairing it but had no immediate success so I decided to have another try at getting my 8K Lister running. I've had the Lister for over a year and never been able to get it started. So I removed the injectors and tubes, checked for good fuel pressure, tightened all connections, adjusted valve lash and made as sure as I could all the air was removed from the system and gave it a crank. It fired up. Yessss. And I had good voltage off the generator. Now the job was to get it down to the shaft. I strung a log chain between two trees on either side of the generator, raised it off the ground with a come along and dropped it into my Otter sled which I then pulled down the hill to the shaft with the wheeler. Since there were no trees there to work with I rigged up a tripod tall enough to do the same hoist procedure out of the sled. The final 20 feet were accomplished with a chain saw winch. I fabbed an outlet junction box from an old generator, mounted it in the hoist shack and ran a power cord from the Lister to the box. All was in place for power down in the shaft. Couldn't get it started again. I had replaced all the filters and found the main fuel filter had a second gasket that was not supposed to be there, so I took that out. Air must have been getting through at that point. Also I discovered the former owner had incorrectly plumbed the water separator. I re bled the system and hooked up a brand new battery. It started and ran just like it came from the factory. Praise God. I now had power. I could get down to the bottom of the shaft and see what headaches were awaiting me from the rain and melting shaft ice that had accumulated over the two weeks I was without power.. It was a mess, but I got my deep well pump running and removed what water had not yet frozen (a considerable amount). Loose ice was shoveled into the hoisting bucket and the remainder I busted up with the jack hammer and hoisted it out. A number of tools were coated with ice and had to be knocked clean and or thawed out up top. Now I can get back to the incomplete thaw I began three or four weeks ago; the rods are still in place. It will take an additional 20 hours to complete, but at least I'm back in business.

    A series of mud slides seems plausible. That would allow for some settling and deposition of silt/muck layers between events.

    Chris, no glaciers in this area. Also if it had been a glacier all the bones I'm finding mixed in the gravel would be well ground up
  4. I worked for an operation that used a very large rubber lined pump to suck the gravel coming off a 250 yd per hour trommel The 1/2"- slurry was pushed about 75' through an 8" pipe then up 10' on to a monster jig. It took a 100hp motor to run the pump but it sure did the job. I'm sure you could go smaller but you're still going to have to have some pretty heavy horse power.

    Not an awful lot to report. I'm about 9' in my drift which is about 5' wide and 5' 6" high at the top of an arch. My gravel is very atypical with large lenses of pure muck in between a jumble of chunky, fine and ground up shist bedrock, large cobbles, angular and rounded quartz and a smattering of intrusives. There's no bedding or layering except for the muck and I even have bones almost to bed rock, one of those being a young mammoth jaw complete with two teeth found 2' off bed rock. It's quite a conundrum. And the gold is not primarily just off bed rock but spotty and scattered throughout the entire column. Got any ideas? Heavy flood event?? I'm also continually making changes to my heat rods for the gravel thawing. My latest iteration should be ready to test out in about 2 weeks. From calculations and prior experience I'm expecting some really effective thawing. I'm also improving my drilling system making it faster and less labor intensive. My bucket hoist has been working nearly flawlessly. I'm ready for the cold to leave though I'm not looking forward to fighting with runoff again this year. Got some ideas how to mitigate it. More soon. Thannks all for your continued interest.

    Doug. That sounds like a plan. How far out are your claims? How long have you had them?

    Life At The Bottom Of A 64' Shaft

    Hey guys, sorry for taking so long to respond. I'm back down in the hole where it's much warmer than top side. Finally got all systems working well enough to initiate another round of drilling and thawing in my main drift. Unfortunately, my heat rods weren't working like I had hoped they would and produced an uneven thaw. Consequently I had a fairly thick wall of frozen gravel on the face and well thawed gravel behind which necessitated a good bit of jack hammering to clean it all out. So I brought all the rods home and reworked them so they'll heat more evenly and also run a good bit hotter. I'll be testing them over the next two days. My young help disappeared when the snow and cold hit and put an end to above ground work. I may get them back soon. The began putting down a new shaft about 150' from my shaft which I'll eventually connect to via my drift. We're thinking the main pay streak is much closer to being below the new shaft. I'm developing a system for operating my hammer drill that allows me to simply set up the various support members, position the drill and then just turn a crank handle to either pull the drill bit into the wall or retract it. I've already drilled about 20 holes using the system and now I'm just simplifying it. Hopefully soon I can include some videos and photos of the operation. Well, that's about it for now. Stay tuned.

    JR Thanks for your continued interest. I'm back in town for the fall and winter[back on line] so I can update easier. It was a slow season for pushing the drifts in my shaft. I spent much of the summer upgrading infrastructure, as it were...new gin pole, new shaft deck, new dead man, etc. Also had water issues that have been so aggravating I just didn't want to be down in all the wet. I did get some thawing done and am very pleased with the performance of my home made thawing rods. I'll start back in the drift as soon as things freeze up good. We're also prospecting an old mine's dump piles [not tailings] and will try to keep that going even after freeze up. Got a couple of young guys helping me out now. Sure nice to have the extra muscle, enthusiasm and company.

    Visiting an old ore processing facillity

    Hey, Leonard...good to hear from you again. Been past that mill many times on my mountain bike. Just love James Canyon and all the mining in that area. It would be great to see renewed activity up there again, but bucking the greens of Boulder County is pretty daunting. Come on back up here to Fairbanks and see my operation this summer.

    Virgin Ground to Mine

    Steve, Your interest seems strong enough that we should carry on further discussion via e-mail. Mine is flintgd@aol.com. Talk soon.

    Virgin Ground to Mine

    Hi, Steve, Harry, Chris and other interested miners, My first reaction in response to Steve's last post is: where does the money come from to drill, rip with a dozer, excavate, haul material, build access road, site grade, etc? It's going to take someone or some operation that has a very good knowledge of the immediate area and its potential and, therefore, is willing to take the risk to get some firm numbers. Next, frozen muck drills fast, but 80' holes are still not cheap. I'll try to get some costs. Working with a dragline is probably the most cost effective way to remove overburden and currently there is a good possibility of a 2 1/2 yarder available. If operations were to begin at the furthest downstream point that would be just past where the two feeder creeks joined, thereby combining two pay steaks. That would surely be the richest ground. Drilling might best begin at the division of the creeks. I'd like to think that by summer's end I'll have good knowledge of the pay on the upper end of Vault [more than 1/2 mile above the junction] from drifting out of the shaft I've put down. So, how serious are you about my ground, Steve? What could you bring to a venture? How similar is a "syndicate" to a partnership?

    Virgin Ground to Mine

    You are right, Chris, about the thawing muck. It certainly presents problems but there are mining operations in the Fairbanks area that routinely tackle frozen overburden as deep or deeper than my ground. Frozen muck rips easily, so you do all your overburden removal beginning in the fall after freeze up. Take a break in December and January and get back with it till June when it really warms up. There's plenty of room in the valley to stack overburden. So by June you have a patch of pay gravel 150 to 200' wide by, say 200 feet deep by 10' thick, That's about 15,000 cu yds. Based on historical reports of gold produced downstream on Vault Creek I'm convinced the pay could easily run over $100. per yd. That would come out to around , $1,500,000. Of course drilling first is essential, and what I find in my drift tunneling will enable us to put some numbers where up to now there is only speculation.
  13. I'm looking for someone to mine roughly 2 miles of virgin permafrost placer stream valley close in to Fairbanks. The overburden ranges from about 45' to 80' so it would require an operation not afraid of going deep. Pay gravels are 8' to 10' and contain gold for nearly the entire horizon. Though the ground has not been drilled, there are several prospect shafts that indicate values of a minimum of 1 oz per 30 yds.. The history of the creek below my claims is rich and much research has been done re. geology and production. Ground is a mile from major highway and town is less than 1/2 hour distant. A prospective operation will need to drill the ground and have large dozers w/rippers, rock trucks or dragline and excavators. There is a large spring that can supply sufficient water for processing. If interested contact Kurt

    Processing Tailings

    That's exciting. I'll be watching your progress too.

    Life At The Bottom Of A 64' Shaft

    Hey guys I have approximately 10 feet of gravel on top of bed rock. I'm only beginning to run my drifts across valley so I'm not able to say what the angle of bed rock is yet. Now I'm recovering from back surgery [relatively minor] but it's going to keep me from any vigorous mine work for several weeks. Ahhh, patience!
