Welcome to Keene Engineering! The world leader in innovative portable mining and prospecting equipment. Family owned and operated since 1950.
Rain, especially heavy rainfall or flooding, can “bring gold back” because it acts as a natural force that loosens and washes gold particles from the riverbanks and bedrock in mountainous areas, carrying them downstream where they can be deposited in more accessible locations for prospectors to find; essentially replenishing gold deposits in rivers after erosion from previous weather events.
When heavy rain occurs, the rushing water erodes the soil and rock along riverbeds, dislodging gold particles that were previously embedded in the sediment.
Since gold is a heavy metal, it tends to settle to the bottom of the riverbed, getting caught in crevices and behind rocks where water flow slows down.
Large flood events can significantly increase the amount of gold transported downstream, further replenishing gold deposits in certain areas.
So gear up and get ready for gold season!
You’ve GoT This!
There is so much more to reclamation dredging than just hunting for gold! Recent flooding has created a demand for cleaning out waterways, clearing out ponds, and dams, clearing boat slips and so much more! Ready to learn more? Read on!
A pool, a spa, a pond, all full. You see it time and time again in news reports of the aftermath of a devastating fire. With a Keene FireFighter you will have an invaluable tool to defend your property. Isn’t it worth the investment to have one and never need to use it? Don’t regret it, be ready instead.

Great news! I feel better and stronger every day. I get home on Tuesday and start my home, Phisical theripy. So I am excited to get home, recuping, and return to work ASAP. My brother Patrick needs me. The poor guy is taking a beating at work, taking most of the calls and sales and keeping Keene up and running. The interesting part is that I can't wait to go camping and drywashing. We had so much fun. It is fantastic to wake up in the desart and breathe in the fresh air. The new DW3 dry waher is behind scheduct due to my accident. The DW3 is getting better and better each time we do out plus the bumper action is working amazingly well on the fine the bump is making a huge improvment in the speed of the machine plus recovery. So happy with the new machine and looking forward to playing in the dirt. ... See MoreSee Less

Tragic Accident*** This past weekend Mark and I were at a outing, at the P.C.S.C. Red Chispa Claim at Benson Canyon and had a great time testing and working on our new DW-3 battery powered dry washer. We came up with many fix's and improvement to start production on our latest model. We drove home and got home safely. Mark disconnected His motorhome and parked in the driveway. Once he went to his custom built jeep that he has been working on. The Jeep would not start. Mark took his remote starter and connected to the solenoid and to his starter. He pressed the starter button and the jeep started. Previously he had his jeep at the transmission shop to fix a leak and disassembled the linkage and reattached as it was all fixed. The jeep slipped into gear and pinned him beneath the large tire. Mark was screaming for help as the jeep was slowly climbing diagonally over his torso. the jeep stopped on top of his chest. Luckily a neighbor woman came to his rescue and Saved His Life by getting in the Jeep and drove the jeep off his chest. The paramedics showed up immediately to take mark to emergency room at Northridge Hospital. When the jeep climbed over Mark, the tire Broke his Pelvis at two points and also the pubis bone at that location. He also broke six ribs at multiple points. His rib had also punctured a small hole in his left lung not the mention some internal bleeding from the pressure from sharp bones. His 4rth and 5 lumbar of his spine broke off some wings of the spine. But Thank God he is Alive and will get better. Mark is alot better shape than myself and due to being very Fit that Saved his life. Tomorrow he will receive some new metal hardware as the doctors use screw and plates to reconstruct his pelvic bone area. Never think you are impervious! Life can be taken from you at any point, no matter what. Live every day like anything can happen. Pray to God and thank him for every precious moment you have. I know mark will survive but deal with some pain and hardship over the next year. Surfing and Mountain biking will have to take a back seat for a while. I am so lucky to have a brother who I love and will always be at his side along with God watching over both of us. We both try to help everyone and will always do the best we can do. Please say a prayer for Mark and wish him well for a speedy recovery. Make is a wonderful person and my brother. ... See MoreSee Less

Mark Keene is a great person and has helped me several times on parts orders. Prayers for a speedy recovery.❤️🩹
You’re very lucky Mark. Glad you’re OK and I hope you have a speedy recovery……, because I need my dredge finished!🤣JK.
This is the latest motor and pump package we are using on the 8" dredge All American Made. 40hp Briggs and Stratton Vanguard. Keene P1500 Pedistale pump with a stainless steal shaft and a Gast 263 air compressor for 2 divers. Mounted in a robust shock mounted roll cage. ... See MoreSee Less
Thanks Keene engineering for never getting me the 3k in mining equipment I purchased and making me feel like shit for trying to get my money back! 🫡 still crushing rocks by hand thatnks.
This is a quick video on the latch we have used for over 4 decades. We use this on our larger power jets quick coupling larger sluice boxes, and more. No one in the world has built a quality latch like this. So we went ahead and built it ourselves. All stainless construction heat-treated material. I have to finish a 10" dredge sluice box next week; we need these to finish the project. ... See MoreSee Less
We do what we have to do to make things work. Or not, in some cases
My favorite sluice was the old A52 with no flare and the riffle latch cammed over in the end of the sluice. Simple but effective. I put a Keene hopper on mine. Many ounces of gold found with it!
Do you sell just the latches? The old submersible could use some new latches. 😊
Just curious where you’re at and how much you pay for the permit to run it
Where's this at
El agua está bastante fría pero no importa porque usan trajes de neopreno bastante gruesos y además cuestan con agua caliente de su propia draga asta yo trabajaría asi
We are working on 8" / 10" dredge sluice box. I thought you might get a kick our off seeing how it goes together. We should be done next week. 36" wide sluice box by 12' with 6" x 3" x 3" x 3" spliter. Also building a 8" oversized power jet with 3 x 3" jet logs reinforced. We built a lot of custom products for the mining community. ... See MoreSee Less
