This is a new dredge we are building called a 8148DE Serious dredge built for gold and diamonds
10 inch or 12
Andrew Thomas Jeremiah Foster I’m gonna sell the 6” and get this lmao kidding!!
Does it come with a boat motor? Big enough to have a party on it while you dredge 😂 awesome

Need the huge expanded riffles somewhere in there. Jus saying . They catch those extra goodies not as heavy as gold

Where’s Guy??
Thanks pat for a great time.
I hope he is having fun!
SO SAD WE MISSED IT!
Hope to see larger dredges up there on the rivers again some day !
Talk about a blast from the past. This is a very old dredge that we built back in the late 1970's and the early 1980's. This looks like an old 2.5" or a 3" vertical dredge. The dredge was very cost effective sold for around 1 k. The compressor looks like a very old Johnson 2 stroke air compressor package. I am sure some of you old timer dredgers will remember this old machine. Check out the bedrock wall on river looks like an amazing place.
I own one of these. It could use some love.
I picked up a clean one for 70 bucks in riverside.
Sweet!
I have 2 😁
Im not sure who the guy without the shirt is but. I think i figured it out
O YEAH that's how ya do it
In 1979 or 1980 the mining shop in Salem had a demo model just like this one that was displayed in a horse watering trough. I thought about buying one but settled for a Keene 2 1/2" on a single tub. That was a great little work horse for me. Got my first nugget with it on Jackson creek, above Jacksonville.
Thanks for your families life long dedication! We really appreciate your dredges and recovery equipment!
Love the color!
Cool !!
Who made that floating pump? Was it Barabo?
We were still using one of those (2.5") to clean bedrock up until about 2013 when it finally blew a pump seal and we couldn't track one down.
Wonder where this spot is
My dad has one
I had the coin and relic version that used inner tubes. 👍🏻
We have a customer that needed a system that would be extremely portable, quick and easy to set up. He is checking some of the crushed material out of his Keene RC46DR rock crusher. The is modified Mini Max with an A52 hand sluice extension. The A52 sluice box has one of our A52EB Sluice Box Extension Adaptor to adapt it to the Mini Max box. We have also provided the custom riffle sections more tailored for crushed material plus the standard riffle as well. It does look a little odd with the differences in hight of the two sluice box, however, to keep it cost effective and versatile this is an excellent compromising design
So does the lower box just have Miracle Matting in it in the top pictures?
I would like to see a flare extension for it
Sweet

These are a few pictures of a 4" gravel pump system working. The river is currently plugged up with decaying vegetation, silt, and muck. By removing the muck, they are bringing the river back to its original status, and this will improve fish habitat and the overall health of the river. He is pumping the waste material onto some alfalfa fields providing the ultimate fertilizer. What an excellent homeostasis for the environment.
How much $...... got a lake that needs help !!!!
I’m guessing that’s not in California...
I could use something like that here !
Yes historic watershed CO cleanings
Too bad that farmer did not get a water allowance to irrigate the field or they could have had a second cutting...
Keene's Double Roller Rock Crusher.
We have a customer that needed to have a rock crusher that would work right out of the box, so I had to explain to him that it takes testing, running and adjusting before you throw in your first rock. So I took the opportunity to run the crusher break the crusher in, I dialed it in several times and even went so far as to lock up the machine with rocks in it. This worked out well for the customer and Keene since we have a very detailed video now.This video is on our RC46DR Double Roller Rock Crusher. The video covers basic set up, operation, maintenance, and troubleshooting. The RC46DR has proven to ...

This is a more upto date cost for a Mini Max dredge upgrade
Certainty not the best video, but those with a Keene Minimax may want to take a look at the Dredge kit from Keene. youtu.be/LNe4uUhAP7w
Just got mine. very nice kit, easy to install, maybe 10 minutes...
This is batch of super max side boxes we are making for a run of 20 more Super Max 6” extreme fine gold dredges
Do you make a conversion for 6 inch mini
We do have a 20" sump. You will need more horsepower and pump for the secondary sluice system and running the other smaller jet.
Do you guys give tours of the production facilities?
That's awesome!!!
Beautiful
Mark and Patrick Keene you are awesome. Great products. Keep pumping them out
Daniel Cowin I know where I want to work
