Keene Engineering Mini Max sluice box, high banker concentrator in action. Patrick Keene 2019 annual Yuba river bash. We are using the Minimax metal detectors hand tools. We had a lot of fun!!

Keene Mini Max in action at Patrick's annual Yuba River Bash 2019. Patrick and a few friends working hard and finding some amazing gold. This is the first of three videos.

The amazing A52S sluice boxes can now be turned into a backpackable high banker and dredge. This one sluice box works extremely well in both fast water and slow water conditions. The folding hopper really does a great job breaking down and classifying the material into a slurry so sluice box can really perform. The dredge set up is simple and effective especially with the larger hopper and the updated riffles. Also, check out the new blaster hose assembly. "A Game Changer"

This is a custom 6" supermax dredge that we built for both super fine gold recovery, diamonds and gemstones. This dredge is equipped with a longer float and frame assembly, plus a 4-foot longer sluice box for gemstone recovery as well. We also cover a few basics on the supermax dredge.

This our latest testing on the Keene A52S High Banker Dredge combinaion. This is a upgraded A52S sluice box that is coverted into a powered high banker and dredge. This one piece of equipment provides hands down the finest non classifying sluice box in the world. The best high production back pack high banker dredge that handles the worst type of material such a clays hard packed. This outperforms all other machine out there due to the long classifier screen and superior spray bar design. The dredge also works very well due to the 1/4” classifying screen this really keeps the production high as well as the recovery. We have gone through many different types riffle designs and as well as rubber mats and screens. The combination of the different screen allows you to optimize the fine gold recover and high production levels in sluicing high banking and dredging. There are so many trick things that make the hole experience so much better.

This is our latest testing on upgrading our A52S sluice box. This is our first high production backpack high Banker dredge. The is designed to handle about 1/2 yard per hour with no problem even in stubborn clays and conglomerate rock. Can handle both a 2" or 2.5" dredge hose as well. Folds down for a small package making it perfect for backpacking into remote untouched areas.

This is our Keene A52S that we have converted into a Back Packable High Banker and Dredge. This add on hopper adapts to our A52, A52S, and even our Mini Max concentrator. We can now take our A52S and turn it into a high production high banker that should be able to process up to 1/2 of a yard per hour. The dredge package works amazing as well especially since we classifying the material down to 3/8 to 1/4"

This is our latest test with the 210 Keene dry washer. The dry washer works great just working out some of the feed issues to work out. Trying to build a dry washer that requires only a 2 man crew is changing at best. Some cool drone footage was misplaced just found.

This is a new 2" dredge model that is equipped with both a suction nozzle and a power jet plus, it incorporates our unique design, leg kit. This new dredge is by far, the most versatile dredge we have ever built. This can be floated and pulled around on the floats and now equipped with the new leg kit for a quick and easy bank mounting. Now it only takes a few moments to switch the dredge from a suction nozzle to a power jet and back again. Having the ability to bank mount the dredge with the new leg system is a game changer.

Finally, We have completed our testing on the new A52S Super Sluicebox. We have been working on this project for years and decided recently, that this is what the market really needed. 8 weeks of spending every weekend out in the field, testing multiple screen and riffle variations. We now have taken the best of our testing and have the ultimate sluice box where a customer who already has a A-52 can upgrade their sluice to the new designs. Equipped with an upgraded Mini Max legs system that allows you set up in just about any conditions, quickly. Upgraded riffle design optimizing, fine gold recovery with the use of expanded metal, miracle matting and carpet with Hungarian regenerative riffles. The new classifier screen consists of grizzly bars, aluminum punch plate and woven wire that provides the perfect classification for all sizes of material. This amazing box, allows you to feed unclassified material without classifying to yield, maximum yardage. This sluice box will handle more material than any other box out there and provide the ultimate in fine gold recovery. You will find more gold with this sluice because, you only have to handle the material only once. Just shovel bank run directly into the box or dump buckets of unclassified material into the sluice. The New A52S sluice box can handle at least double what any other sluice can handle, for its size. This new sluice box is also expandable into a high banker or dredge. We will be offering most the individual parts for most other sluice boxes especially the A52 and we are working on a screening system for an A51 sluice as well.

Patrick Keene and Mark Keene went out this last weekend and completed test #7. Be sure to watch the end of the video demonstrating all the new options that you can build from your sluice box. Once again, we both learned a lot and had a great time. We tried out several new screens and unfortunately with the few minor changes made in production things did not perform as expected. We had to make many changes to the framework and the screens. After making some of the changes in the field we had the system working much better. The good news is the recovery was amazing, the new woven wire top screen really did the trick.

Customers first experience with new dredge.

This is Keene Engineering's Newest 6" dredge that is designed for super fine gold recovery even down to 300 mesh. This new dredge has it all, portability, breaks down into small component, amazing fine gold recovery high power and more. The new flotation system provides superior stability even in fast water and is very comfortable with all the deck space and the large carpeted center platform in center.

Special thanks to Tyler Trembeth for letting us use his footage.

Patrick Keene and Mark Keene went out this last weekend and completed test #6. Once again, we both learned a lot and had a great time. We brought out 8 different test bottles of gold, containing small flat flakes and super fine gold. The good news most everything worked well and some screens worked better than the others. We already have new sets or screens ready for testing for this coming weekend "Test #7". Rain or shine. Most likely rain. Most people would be more than satisfied with what we have accomplished however, we believe that we can do better. We are excited to try out the new upcoming grizzly bars and woven wire. Even in our dredges, we have been getting away from the punch plates due to the gold skipping over however, with a grizzly bars or woven wire, this is not a problem. We just hope that the speed of water under the screen stays at the lower speed and velocity like we are seeing now. The modifications we have made are showing excellent recovery results. We are waiting to get more results from our testers, Kevin Brown and Nick Kieth. Keene Eng. strives to build the best mining equipment in the world, pushing the limits and constantly evolving.

Keene Engineering is bringing you along on our testing and development of our new A52S sluice box. We will be achieving the best high production sluice box ever built. The sluice box will eliminate the need to pre-classify material. This will allow you to move more material with less effort and better gold retention. This is also the easiest sluice box to set up, clean up and work in a greater variety of conditions. We will also be offering all these options for the thousands of a52 sliuce box's that are out there. The box is also expandable into high bankers and dredges. Follow us along and you may learn a thing or two, We are!!!
