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.
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...
