New ultra 5/6" box with Slow Flow recovery system.
I just received some news on the performance of our new 5/6" ultra sluice box. The is being used on a 6" dredge and the fine gold recovery is amazing. I have a few other boxes out there working and I am getting basically the same feedback. The test is being done by a friend of ours that had a dealership overseas and did a lot of the testing on the supermax 6" dredge. So larry really knows his stuff. This is a simple lightweight box with single sluice single carpet system quick and easy to clean up and lighter and more compact than most boxes. The key to the fine gold recovery is the slow flow system. It really helps when you are testing and you are finding a once of gold a day. And the majority is in the 20 mesh and minus and even below 100 mesh. He has dredged the tailing a few time and the gold loss is not even measurable. The only negative comment he made when dredging in the loose pack he did have to slow down a bit. ... See MoreSee Less
What is FineGold..? 🤪 24K..? Let's Call it StarDust 👑🍻 If it is under 150mesh 😅
Yes low flow and speed of water to still push or float off the larger cons.👍
The Price for a dredge like this is 55K. if sold for USA operation the price will be higher due to the new Tier 4 engine cost. ... See MoreSee Less
And delivery is 55k 👍🤣🤔😉
Both Patrick and Mark Keene have been out of communication for the last few days. We have been finishing up a new 8" Supermax dredge that is going to be used on the 40 mile up in Alaska. This dredge is by far the most custom 8" we have ever built for fine gold recovery. This uses all the same technology that we have developed in the supermax dredge. The sluice box is set up with a sump system that captures all the 1/8th and minus material and then transports it into two separate 17" wide by 12-foot long side boxes set up for fine gold recovery. The side boxes are set up with a mixture of miracle matting, a variety of carpets miners moss and expanded metal. We have found a mix of different recovery designs perform the best. There is nothing better than the carpet expanded metal etc for a forgiving recovery system. The Miracle mating is hands down the best for flour gold recovery however it does require a controlled environment. I a dredge system there is a lot of fluctuating water flows different angles on a sluice box so the mix provides optimal recovery in all conditions. We are excited to fallow this dredge up to Alaska and we hope the guys Jeff and will.
This is also set up a very custom hot water heater system developed and sold by some friends of ours. The heater system is set up with the best of the best parts and really decked out for safety. ... See MoreSee Less
Patrick and Mark - thank you. Appreciate all you’ve done for these guys.
Now don't get me wrong. I like the concept and believe it would work just fine , but I don't know any prospectors who would be able to afford this kind of equipment. Most of us scrape by with a full time job and trying to make ends meet. Yes I have a A-52 and It works just fine for me. No where in the province I live in, even let us dredge. Such a small market . Even a lot of states are stopping dredging. I think , and I may be speaking out of turn here, think dryland dredge.
This is straight out of my dreams! Actually bigger than the one I've been dreaming of! The efficiencys, volumes and capture rates are going to be premo! Congratulations!!! Does or will it be named? Lol...
I would like to see a two piece 20 ft long-tom with specially built rifle system...
Looks really cool! Hopefully there will be some video when they get to running it.
Thats awesome, beat of luck, would love to see it running
I saw it get fired up for the first time. Awesome
That’s what I call a Dredge!!! Fine recovery the name of the game!
Sign me up.
That is nuts!
Tony Meeks. Jake Allen Robinson look at this sob wow
Have you tried using the magnetic sheeting that will pick up the black sand which will also stop fine gold in the trapped black sand. i saw that system used at a past gold show and it worked very well.
Holy son of a mother of pearl! That is one nice looking dredge.
That thing looks like a beast

Yesterday we got word from the U.S. Supreme Court that they will be meeting on April 26 to decide which cases will be heard, and which denied.
We are asking everyone to stop what you are doing and WRITE & SEND LETTERS ASAP to the court urging them to hear the Bohmker case.
Attached is a list of the Justices and mailing address, along with Sample Letters.
PLEASE HELP! A few letters will mean nothing... 100's or 1,000s might just make the difference!
I expect all this info to be posted on the Waldo website by tonight.

This is badest of the badass dredges. 8" Super Max with a 75 HP Kubota diesel engine that should have no problem recovering super fine gold consistently. ... See MoreSee Less
This particular machine is being prepared to ship to Alaska. We are very excited do you see this dredge operate within the United States. Most of our larger dredges with sump systems are shipped to Africa, Indonesia or South America. This machine has the super long side sluices for the concentrates and lots of surface area for black sands. We can't wait to see this machine in action and the fine gold capability. Hope to see lots of videos and photos of this machine operating.
I’m guessing this is something you NEED! 🦋🐾
I could reroute a river with that thing! I love the miracle mat! But don't understand the screens! Should I be using one in my highbanker?
So do you have to stand in the side boxes in order to clear a rock jam?
Omg. I would sell an organ to own this bad boy 😱😍
Jennifer Morgan it’s time!
2" headers on the side box??
Does everyone here believe in love at first sight ????! That's awesome

And now I'm drooling ... Thank you Keene!!!
We are working on the 8" Supermax dredge and it is turning out really nice. The belt guard was definitely one of the tougher ones we have ever built. I hope to have it assembled tomorrow and we will provide some additional pictures. I wish I had one of these back in the '80s through the mid-1990s, imagine the additional gold we could have found. ... See MoreSee Less
What size motor will be on it. And why 2 different sizes pumpd
Jealous of your R&D
Hi Mark Keene and a hi to Pat Keene lets see if I can make Mark blush?? Lol
Twin turbskis. she should be good on 30 psi or 60 😎😎😎🤫👍😂🤣
This is a 2.5" header box that finally came in. It was a lot of work to adapt to A52S. The problem is the sluice box header box is 10.25" so we had to manufacture a custom adaptor to make it fit a sluice box. We had to Heliarc weld the seams closed. ... See MoreSee Less
Beginning of a beautiful relationship
I’m still waiting on the one I ordered for one of my customers.. glad to see it’s in 🤣👍
Aboit time yall made a way for this. Ya missed out on lots of money from after market guys making them. But....I had mine made and it was very simple to bolt to the factory a52...
This is the piece you were waiting on to go testing when we talked last week. Will you test it with both a suction nozzle and powerjet?
Will this fit on the mini max?
Now that I like!

Next week I will publish more on the high banker dredge hopper. I did not like the water flow with the dredge attachment. We already came up with a good fix. I just have to make it Monday and go out testing again. ... See MoreSee Less
