Gold Mining! did some gold mining last summer up around Carmacks, Yukon. this was close to the end of our season, we just got the trommel on site.

this was last season and we've changed a bunch of stuff on the trommel etc etc. it has been working a hell of a lot better this season and we're getting into some good gold. the spot it was in this video wasn't paying very good, we're further up the cut now and things are looking far better. this is the last year were gonna mine this Creek. next season we'll be heading to another Creek expanding, getting more iron that kind of thing. but thanks for the advice sounds like you know what your talking about!!

Those sluices need to be longer. 8-10 feet of Clarkson riffles and 16 feet of raised expanded steel riffles. That allows for the shenanigans with the washplant. Shut it off, shut it on, over feed it, get a surge, etc.. Those are all things that cause the gold to miss the first few riffles. Beautiful setup though. I hope you guys were successful. I always say, nobody deserves to go broke gold mining, everyone deserves to at minimum make their money back and keep going if they wish. Problem in today's times is the cost of the equipment. Guys have to get 100 ounces just to pay for the equipment. It's easier than that. Buy a 20 foot long section of 1/4 inch 4 foot diameter steel pipe. Get a heavy duty trailer that is just a frame. Set up some legs, mount 4 trailer axles to the legs, and make your screening sections inbetween the tires of each axle. Build a sheetmetal dump box under each screening section with some 16 gauge steel. Dump the 1/8" minus into it's own sluice, some Clarkson riffles 1" by 1/2" for 10 feet, and then add 16 feet of raised expanded steel riffles. Start the sluice at 4 foot wide and expand it to 6 feet wide when it turns into expanded steel riffles. You can ADD water to the bottom end of the sluice, though you cannot take water out unless you want to risk losing gold. Then make the other screening section of the sluice 1/8" to 1/2" and make THAT sluice run nothing except Clarkson riffles (of course the tail of the sluice MUST include at least 8 feet of expanded steel in case some fine gold crept thru the first screening section. Then the discarded material that runs out the end of the trommel will pass thru a sluice with boil boxes, nugget traps, and other fixtures that will catch large nuggets. Start this sluice with 4 boil boxes (8 inches wide, 4 inches on each side of the steel plate that forces the water underneath it), then some deep nugget traps that are 8 inches by 5 inches deep, and then the flatbar riffles on the same angle (negative 15 degrees) as the Clarkson riffles. Make an array of heights. Some 3 inches, some 4 inches, some 2 inches, and space them double the height. For example space the 2 inch riffles about 3.5 or 4 inches apart to give the same effect as a Clarkson riffle, there'll just be no lip for material buildup to occur. Hopefully the swirling motion will kick out the larger rocks. There will have to be one hell of a water pump for the nugget trap sluice so it can kick out the large rocks. Then the hopper; the hopper will screen anything larger than 2 inches and wash it thoroughly and then discard it so it doesn't run thru the trommel. The trommel will deal with only 2 inch minus rocks. Never know, you may come across a 10 ounce nugget and ya DAMN sure want to catch that nugget even if it's 1/4 ounce of gold attached to quartz.. As far as the trommel goes, I see the work someone will have to go thru if those screens wear out. Designing a trommel, you want to account for the wear of the screen. Make it so perforated 16 gauge metal can easily wrap the inside of the trommel's screening area giving it it's screen. Possibly you could do the same with the wire mesh, make it so it's easy to get in there when the screen wears out. Gotta make this equipment easily fixable or you'll get shut down for weeks.
