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!

Weed dredge.
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.

How do I get one of these flyers when they are finished? I just bought a A52S and need some accessories.

So when will the high banker box come in for the A52S. CHA been back ordered?

Can you guys send 2 inch backpack dredge to Australia

It’s been a while.
I finally started prospecting with the dredge.
Took a long time to obtain the license.
It’s a wonderful machine the super Max 6inch.
It’s working well in the remote waters of Sierra Leone.
Easy to transport to remote areas and assemble on the spot.
The diving gear is great.
I have dived myself now for some days.
It’s a great experience.

Have the sluice. Do you just sell the Hopper?

James Kendrick

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.

Cost?
