  1. After much research and mapping, I believe I have narrowed down the area where the old timers found ounce sized nuggets back when my creek was actively being mined. Two areas in the creek fit the description. I had to piece together info from multiple reports and geologic descriptions, then use property boundaries, court house, records, geologic maps, lidar maps and lots of hiking and scouting to find these two areas seem to match. Only time and lots of dredging will tell if i got it right or not. Hope you all enjoy the video and stay tuned for more.
  2. Last night I read a very interesting (IMO) article by Chris Ralph in the June, 2019 issue of the ICMJ (https://www.icmj.com/) titled "How Long Does It Take to Find and Recover an Ounce of Gold". There are a lot of caveats Chris lists, which makes it dangerous for me to summarize what was written. Further, there is a fine line between showing results from a magazine/journal which needs money to stay afloat and requiring interested parties to simply pay for a subscription. IMO, anyone halfway serious about searching for native gold (and there's more there than just gold) should be a subscriber. Most importantly, his estimates certainly depend upon the ground you are covering -- this should be obvious to everyone and I hope simply mentioning it will squelch any attempt to quibble at his results. Basically there is a lot of uncertainty around Chris's numbers, which he is well aware of, but it's still interesting to hear from an expert who has used all of these methods countless times. I was surprised at some of his estimates. In order longest (least efficient) to shortest: Panning: 42 hrs, Metal Detecting: 40 hrs, Sluicing/Highbanking: 30 hrs, Dry Washing: 30 hrs, Dredging: 20 hrs, Hard Rock Mining: 8 hrs. I think it's worth emphasizing that this is a time efficiency, not a cost efficiency. Panning is clearly the least expensive with hard rock mining by far the most. Chris also points out that the leadup time/research/preparation & cost are vastly different -- hard rock mining being the obvious extreme.
  3. Had a great weekend out prospecting and dredging a club property in Virginia. Got to meet some new people and have an overall great time camping and dredging. So i just started prospecting this creek and club property this year. Ive panned and dredged it a few times, all was basically sampling activities. From research of old workings and looking geologic and lidar maps i choose a specific area to focus on, and the last time out sampling with the dredge started to sniff on decent gold in a 1 hour sample hole with a 4 inch dredge. The area consists of a spot about 100 yards wide in which the creek has always had to cross since sheer cliff walls bound the stretch on each opposite bank. A gold bearing feeder also comes in within the stretch which is an added bonus. The thought is, is that since the creek has always had to cross that 100 yard stretch then an old paystreak should cross it somewhere was well, from back in the days when this area had more conducive climate to being able to transport gold. From what ive heard and seen within the club most people avoid prospecting this creek, due to difficult access, deep overburden and generally not finding much gold once they get in there. So i have not heard of decent gold coming from it. But the old history reports say otherwise and state that it is one of the few creeks in this area that was never placer mined due to difficulties that the old timers in the 1800s couldnt overcome. Sounds like my type of area, if im going to prospect a club property. Sample dredging the creek a few weeks before Memorial day weekend. Notice the 15 foot tall silt bank behind the dredge, its all alluvial flood plain material. Gold from the 1 hour sample hole with the 4 inch dredge. Not fantastic but far above the back ground gold count for this creek. Camp all set up and the dogs are happy with it. Getting the dredges set up. I decided to bring the 5 inch since the ability to move more material out weighed the extra weight in my opinion. Dredging away. Luckily the overburden depth was only about 2 feet at most, so i was able to cover some ground with the 5 inch. Got about 2 full good days of dredging in. Found some Indian pottery while dredging. Always awesome to find Indian artifacts. And the best part, Success! Good gold with some nice pickers. 2.4 grams on Saturday and 1 gram on Sunday. I love when research, sampling and hard work culminates into some great cleanups in new areas. Got a new spot to continue to work know, and i know there are more pickers and possibly nuggets nearby, just gotta get my dredge nozzle over them. Hope everyone else had a great memorial day weekend. Heavy pans!
  4. https://www.americanminingrights.com/dredging-in-california-next-year/ Whether there is any truth to this, or it is stonewalled by legislation remains to be seen. Interesting though.
  5. It looks like the HP-500 pumps from Keene are made to drill and tap for drain plugs.
  6. All the bad weather, snow and to many things I need to take care of no chance to get away for a trip to gold country, been watching tons of YouTube gold related videos on prospecting related stuff and the occasional Jeep roll over compilation just to scare me into not doing that stuff with my Jeep on the gold trail😲. Lots of ideas on the web for idle hands to foolishly venture, not that I don’t have anything to occupy my time, but a little sucking device somehow seemed like a good idea, so off I go... I’ve been building my little Jeep friendly recirculating sluice and thought I would try making a nozzle for use with the pump I already own, just a few pipe fittings and a little part here and there. I already have a Keene high banker setup and 90gpm Honda pump I can’t use in California, but something small for Jeep travel where it’s ok might come in handy, so I build the first one paying attention to everything I can think of to reduce friction and any head pressure and the little bilge pump was inadequate for the task. searching the web for 12v pumps it’s hard to find anything that produces both volume and pressure at a reasonable price, the rule 4000 utility pump was the most powerful at 66gpm open flow and max lift of approx 30’ with over half its rated volume at 15’, but at a cost of 20amp hrs power consumption, they even made a two stage model rated at 134gpm same rated lift. Only problem the rule evacuator pump line are discontinued and I could only find one seller in the US that still had 3 in stock, every one else was out and the product is no longer listed one the manufacturers web site. I passed on the rule4000 and found a reasonable priced 1000 gph utility pump with a rated max lift of 7m out of Korea and ordered one, it won’t arrive until sometime in April I find out so we’ll see but I suspect it was a waste. I should have stopped reading about water pumps, but didn’t and found another 12v pump that looked better with more volume than my bilge pump or the Korean pump and with a rated max lift of 7m burning only 13amp hr from my battery and ordered it. superior pump came today and I outfitted my nozzle with the new pump along with a water proof power switch and cigarette lighter socket power cord, even with the power of this pump (1/4hp) the suction is inhibited by the discharge restriction and lift enough to make it not quite just enough suction to be practical, however pumping directly into a container without the lift it will suck dirt and gravel more than enough to be worth trying out for bedrock cracks. Everything but the battery weighs 8# total out of the water and in the water it’s slightly negative buoyancy keeps it on the bottom without feeling heavy it also feels fairly well balanced. Before the superior pump arrived eBay kept nagging me about the rule4000 and I still couldn’t find a replacement for this now discontinued pump, so with only the 3 left I figured it was only a couple hundred and I’d might regret it more later if I passed cause I’m on a mission now and pulled the trigger on the rule pump, estimate it arrives on Friday. At over twice the power and capacity of the superior 12v pump it should pump material into my little highbanker if I get a larger battery. Anyway more to come...
  7. Beautiful day out on the river doing some scouting and testing of new equipment. Only got to punch one sample hole. Little too much overburden at about 4 feet. Got a little color, just need to find more easily worked ground.
  8. Steve - I know this is an old thread but i cant help but notice that the sluice on your 6 inch in these pictures looks a lot like a sluice i picked up with an old 5 inch dredge in Kentucky lol. I havent been able to find out anything about this box on any of the other forums. What can you tell me about it and do you have any pictures on how is is supposed to be set up right where the flare and sluice mate up. Any info and more pictures are appreciated! Thank you,
  9. Hi All, I have a 2" Keene dredge and a 3" Keene HighBaker, I use the 2" 90% of the time cause the 3" high banker about to much for me to get to the small creek I go to. I get very small gold at this creek but a lot of it. Do you think if I fit the 3" sluice box on my 2" floats I can get better gold recovery? I never run my Honda full blast anyway. I was just thinking the bigger sluice will keep more small gold. What do you all think? Thanks Dean
  10. Before I waste my money,does anybody know if I can add a 2.5 inch Proline swivel nozzle to a 2.5 inch Keene suction nozzle? Maybe cut off the angled end of the swivel nozzle and then weld to the intake end of the suction nozzle, sure would make the hose easier to handle I would think? how does the swivel joint work anyway? I prefer the suction nozzle in shallow creeks to avoid losing my prime.

  20. I was really heavy into very late fall and very early spring dredging in the late 90's time frame. This photo is from 1996 and was taken by my friend Rich Lampright. I worked a lot at Crow Creek Mine, which is glacial fed. It runs very high and fast in the summer when the glacier is melting. The best time to dredge is in the winter months when freezing temps bring the water levels down by over 50% and the water starts running crystal clear. It also made for some very cold dredging at times, but properly outfitted with a good drysuit you can stay surprisingly comfortable. Usually. Funny how some days I really was cozy and others it was just plain cold. I could operate well down to about 15 degrees. Below that, and the water literally froze in the sluice box while it was running. I resorted to subsurface dredges for the coldest spells as the box being underwater did not freeze up. But even then you see weird stuff. Ice crystals floating in the water build like snow drifts of slush behind rocks on the bottom, and giant balls of slush form on the pump intakes, eventually plugging them. Why suffer this you ask? I was seeing multi-ounce days working by myself. I took a lot of gold out of Crow Creek; even after paying a percentage to the owners it was good. In fact the best dredging I ever did. My best day in there working a 6" by myself was over 8 ounces of gold. This was my favorite dredge, my old Keene 6" with twin Honda 6HP pumps. This model was made with a molded marlex powerjet in two pieces - the jet and the flare. The jet and flare assembled was about six feet long but I could just toss it over my shoulder and carry it in one piece it was so light. The dredge had a stout frame with a lever handle leveling system, far superior to the later slide the box back and forth nonsense. The box was a well built single run sluice that I preferred over later double-decker designs. I never should have sold it. I did however, to Brian Berkhahn, and he also got a lot of gold with it. And I know he now also regrets selling it. It was the best Keene dredge I ever owned. Mark Keene told me they stopped making the marlex jets due to a high failure rate with the process but they should have either fixed the process or just charged more to make up for the failures. It was an incredible advance in the technology, and amazingly after all the years of use the inside of that jet never showed more than light scuffing. I think it was actually more durable than steel jets. This photo is first thing in the morning, breaking away all the ice that has formed around the dredge overnight.
  21. I have a large collection of Keene Engineering catalogs, parts diagrams and assembly instructions going back decades. Many I have not seen available anywhere online. I am starting with the easy stuff but will be scanning and posting the older stuff also. The new download page for Keene Engineering items is a sub-category of the new Downloads Area. I just uploaded parts diagrams and assembly instructions for the older P90, P100, P180, P280, P350, and P350 pumps plus several full line catalogs. I will be adding things as I get the time and am in the mood - some of the docs will need some cleaning up before posting. I will notify forum members when I make new uploads.
  22. Had a great day out last weekend. Temps got close to 60, but still had to use the wet suit heater. Definitely a worth while trip, with some nice coarse chunky gold. Most of the gold was found caught up in a quartz vein. Hard to tell if it actually came from that vein or just got caught there. Will be crushing some of the vein to see if anything comes out of it. Either way the gold did not travel far at all which has been typical of all the gold found in this stretch of creek. Hopefully ill be able to dredge there one more time before the end of the year. Currently sitting at 0.90 oz for the year would love to get that last 0.1 to make an ounce for this year. We will see.
  23. Looking to pick up a 4in in the next bit here. Keene? Proline? Or will the difference even matter for a novice? All opinions appreciated.
  24. Or at least not published on the internet before. If you all have not been following my Chisana Story you will want to check it out. Lots of rare photos of Alaska locations and history plus lots of dredging photos.
