We are demonstrating the latest sluice box upgrades for the A52 sluice. We are taking you through a series of outings showing the progression of building the perfect sluice package. This is about the 4th trip out with the new box and more changes every time we take it out. We are also demonstrating our latest Keene crevice trowel, and honestly, this is a game changer light bulletproof the ultimate digging tool. We are showing the new folding leg system, New classifier screening system and some new rifle designs and mats for the sluice box as well. Once perfected we will offer these upgrades as a package or independently.

This is a quick video on how to prime a centrifugal pump on a gold dredge. Covers a few basic techniques and tricks.

This is a 4" gravel pump system that can pump high percentages of slurry over long distances. The pump can handle up to a 3.5" sphears. Used for mining applications and reclamation. Powered by a 60 hp diesel engine.

The Mini Max Power Sluice Concentrator is one of the most versatile packages that we have ever made. Whether you’re working in river
banks, desert placers or just cleaning concentrates from larger equipment, this Multi Tool of Prospecting will always be a part of your arsenal. This multi-purpose package includes interchangeable matting for the lower sluice box, interchangeable wire classifiers for the flood hopper classifier assembly, lightweight easy-adjust legs for unsurpassed setup time, and a flare that converts the unit into the Ultimate River Sluice. A newer stronger American-made 2,200 GPH 12 volt pump provides greater flow and increased head lift. This newly redesigned unit is now equipped with an improved ball valve that allows for more precise flow control and connects to a longer 8 foot pressure hose. A new flood header provides smooth water flow over a slick plate into a 6” section of Miracle Mat. The top assembly lifts off easily to inspect the lower sluice. Material is then washed over a removable 1/4” classifier grizzly screen removing waste gravel. The lower sluice is lined with 13 inches of our newly improved Miracle Mat placed under 10 inches of expanded metal, this duo recovers both fine and course gold and can handle larger volumes of material. When using it as a concentrator system, replace the high profile riffle with a second section of Miracle Matting and replace the grizzly screen with a finer 1/8” woven mesh screen, converting the unit into a 34 inch Super Concentrator. When used as a power sluice, you can expect a capacity of up to 1/2 of a yard per hour and about a third of its capacity when used as a concentrating machine. This device can also be operated by a small single gas-powered pump (P90G Pump Kit located on page 13). This ideal backpacking unit folds up into a compact size of 36” x 14” x 7” and weighs under 23 lbs. Pin-lock folding legs make adjusting elevation a breeze. The included
flare converts the system into a hand sluice as shown in Concentrator Kit- Model MMPSCK. American made and built to last.

The Jabbit Sluice Stand is the only deep water, self-driving sluice stand available. The perfect companion for the Keene A52, A51, and MiniMax Sluice. Simply “Jabb-it” into sediment, slide your sluice
on to it, and you’re ready for some serious sluicing. The Jabbit can handle depths of up to 30 inches of water. Your sluice box will float effortlessly and correct its position for ideal water flow with its “Weathervane Swivel Action”.The sluice slides off easily, making clean up and setting back up a breeze. Only 12 lbs.
Drilling into the side of your sluice’s flare is required.

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 be a real workhorse for over 38 years. We have upgraded it with a double roller system that does require more maintenance and a higher level of proper setup. We walk through step by step procedures on startup, operation and some detailed instructions on appropriate adjustments. The upgraded crusher can produce up to 2000 pounds per hour and deliver crushed powder around 50 to 100 mesh in a single pass.

Keene's 160 series Dry Washer and Wet Washer is packed full of new improvements. The dry washer has been upgraded with a larger Blast gate providing greater air pressure control under the riffle board. The box now comes with bumpers for greater vibration control. The Wet kit has been completely upgraded with a all new hopper / grizzly system, larger pump, and a all new longer sluice box for higher capacity and greater fine gold recovery.

This is our latest test on the large 210 Dry Washer. This is after 20 plus test trips. We are basically ready for production on the 210 dry washer. We are working hard to develop a feed hopper that provides a smooth even flow of material into the 210 vibratory shaker deck screen. A smooth even flow is a key to high production and fine gold recovery. 04/18. Mark

This new model features a hopper that is nearly twice the size of earlier models. It’s longer and wider to accommodate greater volume. It also comes with both 1/4 inch and 3/8-inch removable classifier screens. Both screens are curved to improve degrading of clay and hard packed material and accommodate a rounded shovel. The new recessed spray bar is protected from impact of larger rocks and provides stronger and wider spray for a more complete washing of material. This Power Sluice is 20 inches wide, 8 feet long and capable of processing up to 4 cubic yards per hour. Model 17820CA includes only the concentrator. Model 17820 comes complete with a P185H motor; pump FVA 25E intake assembly and 50 feet 2 inch Nylobraid hose with couplings to complete the system. Model 178203 is equipped with a 3-inch suction nozzle and 20 feet of 3-inch suction hose. This combination makes it possible to vacuum material directly into the hopper where material is processed, and classified. Optional 4-foot extensions with legs are available in (Model #177E). This new improved Model can now handle up to a 4” dredge input. Larger engines and pumps may be required due to particular working conditions. The hopper is designed to accommodate intake sizes from 2 1/2, 3 and 4 inch.

Pat Keene's trip to the Yuba 2016 Mini Max

This video covers some of Pat Keene's Annual Yuba Bash. Shows some of the guys using the HydroAir 12 Volt compressor system. This is the ultimate tool for sniping for gold in the rivers. They had a great time found some amazing gold, what else can you ask for.

Chris Woods and Mark Keene are testing a new php500 pump with a series of different power jets and jet logs. Demonstrates a lot of testing of different facets of pump testing.

This shows the power and pressure of the PHP500 pump when used with a blaster hose for under water clearing of cracks and crevices

This is our newest pump we have come out with a PHP500 pump. This video demonstrates how to prime the pump.

This is a very basic instruction on how to prime a small pump. This short video shows Mark Keene priming a P90GH pump.

This is an older 151S video covering basic sales information and set up. This is a little outdated in the riffle board. Now the three layers are all attached to the aluminum riffle board.
