The Quest For Gold Lies in All Of Us
My wife and I have been for years- and myself since I was a young man- passionate seekers of gold. The lure and excitement of discovering gold, freeing it from the bondage of a subterranean existence - is more than just a "fever", it is a passion which never ceases, a captivating desire which only grows. We love prospecting anywhere, especially in northern Nevada. In extreme northern Nevada, Elko County has produced some spectacular gold. Did you know one of the largest finds in northern Nevada was a stunning and gargantuan seven troy pound nugget from Elko County? Not ours, but think how exciting that was!
Over the years we have discovered a wonderful collection of nuggets and specimens and have now decided to offer them for sale to other folks who enjoy the fascination of gold.
Our gold nuggets surprise us with amazing shapes and personalities, coming from deep down in undisturbed Earth. They've not been hammered by heavy erosion and alluvial river wash action. Our gold nuggets come from very near the spot where they were first formed, and we are extremely cautious in unearthing them.
It appears they've hardly moved at all in their thousands of years since transforming into existence. The intricate shapes and patterns of these nuggets place them at a whole other level of Nature's phenomenal designing accomplishments. We are so thankful to be able to share our discoveries and stories with you and hope that you find entertainment, joy and pleasure in our presentation of them, as we do.
You may be a collector, an investor, or a fellow prospector - whatever the reason that brought you to goldnuggetman.com - we appreciate your interest and spending time with us. Please be sure to put www.goldnuggetman.com in your favorites so you can check back often, as we will always be updating the site with new and interesting stories and comments - AND ADDING MORE GOLD! ...

Keene Engineering sells for than just gold dredges.
We manufacture a custom dredges that are built for reclamation industry. Dredging out lakes, Clearing Docks, Recovery of artifact and much more. Currently we are focusing on a dredge that removes invasive weed species. There is a huge problem here in the USA many or our lakes are being chocked out from invasive plant life such a milfoil and other plant life. In many cases the evasive species are even destroying multi use areas and even real-estate values are be destroyed. It gets so bad that is makes it impossible for boat to get through or even going swimming.
Keene has been working with some scientists, biologist,s and other authorities on the subject to perfect the perfect dredge system. We have come out with a multi-screen separation system we are currently calling the Weed box. The Weed box is fed by a high-powered 3” 4” or 5” dredge. The material then passed into a hopper that works much like a gold dredge header box. The material is then pumped on top 1/4” aluminum punch plate and builds up and moves forward on the screen. The build-up of the screen is then racked with a typical garden hoe and pulls the material into the hole in the back of the table. The material falls through the opening directly into the home depot style 18 gallons tubs. One of the unique features we have on this table is the triple screen system. The triple screen captures and the fragmentation and seedling that comes from the plant so it greatly reduces the chances of any regrowth the next season. The screen can be removed in a matter of seconds and easily cleaned. The big hose on the bottom is also a game-changer since the water can be full of Turbidity and can easily be diverted to the bottom of the lake or off to one side to keep the divers from becoming clouded out. The tubs should be modified with some hoses drilled in the bottom so some further water drains is possible. The tubes can be stockpiled on the deck of the boat or transferred into a larger container with drains.
This weekend we are placing the whole package on top of one of our 8” dredge floats and frames. I will show some details next week. ... See MoreSee Less

This is something new we are working on. This is an A52S sluice with our new high banker hopper assembly with dual RP2200 pumps make for a nice silent high production high banker. Roughly 1 yard per hour.
The Price is roughly 1188.00 ... See MoreSee Less
Have the sluice. Do you just sell the Hopper?
It doesn’t matter how much dirt it can take if the capture system is terrible, miracle mat is the worst, you should team up with dream mat guys it would be fool proof then
Nice! I have the A52s already. Do you sell the washer section separately? What do you get for it including the pumps? How much of a waiting list is there?
Looks awesome. What’s the total gph on the pumps?
Y’all make this hard to resist. Really hard.
One pump kills a battery in no time. I can't imagine running two
Looks awesome. I was wandering what is the best degree⁰ (angle) to run the A52s with clean up mat?
Be nice if the high banker wouldn’t be on BO ,,,waiting !
My rendition I put together in 2019.
We are extremely excited to present the next generation of a dredge designed for the recovery of super fine gold
This New Super Mini Max Power Sluice Concentrator unit is the most versatile package that we have ever offered.
