Diamonds, a Possible Cure for Gold Fever.

by Karl
(Florida)

Following the writings of Dan Hausel this past summer, I decided to give diamonds a try. I watched all I could on YOUTUBE on how it is done in Guyana and the Congo. Then, I studied use of the Saruca, essentially the same concept except the Saruca is turned over after processing and it looks like the folks using the bigger round baskets merely throw out the lighter stuff around the edges and sort through the heavies in the middle.

I went to some streams in Colorado where diamonds were being recovered more or less by accident while prospecting for gold or where gold mining techniques were being used to catch diamonds.

It took me three weeks of failure, a trip up into Wyoming to recover some peridot and more than a few nights pondering where it all went wrong. I decided to drop back into Colorado and give it another try.

This time I searched the stream bed and sampled until I found a thick dark gray or bluish clay and once again began my search. 13 raw diamonds later, I am a dyed in the wool born again diamond hunter. Only one of the 13 I found was gem quality, a small octahedral around .25 carat but that has lit the fire.

Just wondering if any others out there have gone after diamonds either here in the US or further south and if you don't mind sharing just exactly what you did to maximize recovery.

Stan's response: Holy Moses Karl! You just hit my hot button. Bravo for you! I am a big fan of diamond prospecting. I plan to cover this topic in a big way down the road in a few weeks or months.

A number of years ago, I spent a month wandering around the Gran Savannah of Venezuela. I was following in the footsteps of Pino Turolla (Beyond the Andes 1970 & 1976). Using Pino's maps, I hit the jackpot on a feeder stream of the Caroni River. The entire plateau (between the Caroni and Paraguas) is underlain by alluvial diamonds!

I'll have much more to share about this expedition, along with a bunch of photos. I paid for my entire trip and expenses nearly 3 times over. I used a black light in the early evenings which made many of the diamonds fluoresce right in place. It was like taking candy from a baby.

All of the diamonds were sitting on top of a bluish clay layer. Mother Nature had done the mining through erosion, exposing huge lengths of the clay layer to plain sight.

I love raw diamonds!

Small Diamonds & Lots of Garnet
by: Karl

Count and amount 7 small diamonds and a bunch of garnets. A great trip with prospecting for diamonds followed by testing of a couple of German mine detectors for potential use as electronic prospecting equipment.

Will have to submit a report to the company here in a couple of days but all in all a very interesting trip with gold being found as well and one of the mine detectors, a pulse induction unit with a UXO mode giving a Minelab GPX-4500, Minelab SDC 2300, Garrett Infinium LS and NOKTA FORS Gold a run for their money on large deep gold.

The other one, a pulse induction unit as well could go head to head with a Fisher Gold Bug 2 for small gold. I'll try to start another post later in the week and upload some photos.

Stan's response: Thanks a ton for the great info Karl. This is super important to us.

Is there any way to upload photos?
by: Karl

Stan, is there any way to upload photos on here? If I'm going to brag I want a visual to really rub it in. :-)

Stan's response: Sure Karl, when you make a new forum post, right under the text box, you see this:

"Upload 1-4 Pictures or Graphics (optional)[ ? ]

Add a Picture/Graphic Caption (optional)

Click here to upload more images (optional)"

You can share up to 4 photos at a time.

Can't wait to see what you have to share with us after your expedition.




T-18 days and counting!
by: Karl

18 days and counting until my return trip to look for more diamonds. Purchased two UV Scorpion lights for night time fluorescing any diamonds on the surface.

Taking a heavy duty Fiskars all steel shovel and a post hole digger for getting down into the "zone" to pull out diamond bearing material for washing.

Have found out since my last outing that what I thought would be considered industrial diamonds are actually considered fancies. Here I am holding out for perfectly clear but now, I'll take em all.

Thanks to Peter Mikelis' YOUTUBE video on Guyana Diamonds and other videos on mining I have an even better grasp on the whole "busting the sieve" stage in recovery.

This time all obvious diamonds will immediately go into the catch jar and the remaining circle of concentrates with each sieve load will be placed into a bucket for careful going over when I get back home.

I am hoping to engage in two of my favorite activities, fishing for wild/native trout and mining for diamonds. I'll keep this FORUM posted as things develop.

Stan's response: Wow Karl! Please keep us posted and let us share in your adventure. We already can't wait for your next update...

Diamonds in the SE USA
by: John Smith

I have read accounts of diamonds being found in the areas surrounding Phoenix City, AL. This was in an older issue of the Gold Prospectors guide of properties 5yrs ago.

These reports were from the 1800's when gold mining was happening before the Civil War in 1862-1865. It might be worth looking as this area is in the foothills of the Great Smoky Mtns., one of the oldest mountain chains.

If garnets are an indicator, the whole area of NE Alabama could be ideal as garnets are found almost everywhere here.

Diamond Catch Secret
by: Dave

There is a way to recover more diamonds from your placer materials. It is simple, just wash your concentrate in Dawn dish soap, half a cap full in a five gallon bucket is all you need. I have a half inch drill with a paddle bit for mixing mud for drywall or tile work. I mix the placer material in the Dawn water for about a minute and its ready for the grease table.

The reason for washing is in nature there are grease like substances that the diamonds get caught up in. Like pine tars and pitches, even dead animal fats. They will coat the diamonds and if you try to catch them with a grease board or table, they just run right through and back out into nature they go. Once they are coated you can't recover them with grease. Good luck.

Stan's comment: This is brilliant!

Dan Hausel's Formula for Diamond Grease
by: Lost Adams

Hi Bill,

When I was at the Survey, we used a mixture of 10:1 of Vaseline to Paraffin. This was placed on a grease table and we controlled the water flow and size of material that was run on the table.

I hope this helps.
Dan

I saw what the table was like in one of his publications and it looked like a series of stepped trays maybe 8-10" long by 10-12" wide.

stacked to overlap.

That's the best I can do without making or finding a picture.

Anybody else have any experience or resources?

Diamond Catching Grease
by: Dave

I have used every type of grease to catch diamonds. On my first try, I used axle grease. It worked really well. The only drawback was when I went to separate the grease from the diamonds. I scraped up the diamond bearing grease and put it in a pot of water.

My wife's new cookware worked just great, so I thought. I brought the pot up to a boil and melted the grease, and the diamonds fell to the bottom of the pot. But, there was a problem. I did not account for the axle grease smell. Boy, was it bad. It stunk up the whole house, and that new pot didn't look so good either. That was 40 years ago and I still hear about my diamond pot experience.

Here in Wisconsin, its cold in the spring and fall. I usually use either petroleum jelly, or a petroleum jelly mixed with bee's wax. They work well in very cold water, and thank God they don't stink up the house when you melt them.

I save the grease and use it over and over again. I usually collect up a concentrate of gold and diamond bearing sand with very small gravels. Then, I run it through a sluice box with a diamond race coming off the box. Diamonds are usually caught in the first two/three feet of the metal diamond race. Good luck. Dave

A 3-Day Drive to Reach the Raw Diamonds
by: Karl

Nice website Gregg and thanks for the grease table tip Dave.

My biggest problem is a 3-day drive to get to Colorado from Florida. I don't like going where there are lots of people but have dabbled in the whole Arkansas diamond mining deal at the state park.

I just got back from there and after careful thought and having surveyed the situation, I have decided that I will go back with a 6 foot probe. I will probe down until I hit the gravel deposits they talk about. I will probe along to get an idea of how it is running and then with a set of post hole diggers, go down and remove the gravel from that level and then check for diamonds.

That might have to do until the weather breaks and I can get back out west.


Wisconsin Diamonds by Dave!
by: Lost Adams

Dave, what is your formula for the grease on the table and how do you make the sluice for the Grease Table? I know what my formula is, I got it from Dan H. 5-6 years ago. Just wondering what yours is. I'll reveal what he told me when you tell yours.
PS. they're probably the SAME or similar as physics doesn't change.

Rough Diamond Prospecting
by: Gregg

It was interesting to see that someone is finally looking for diamonds. I have been mining and buying them for 20 years in West Africa, mainly in Sierra Leone.

I have written several e-books on the subject, if anyone is interested. I have the books on diamond and gold scammers in West Africa as well.

You can go to my website at:

www.greggsgemhouse.com/page39

and see some of the e-books there. They are on Scribd too.

If I can be of any service to any of you and you as well Stan :), let me know.

I am going back in three weeks to mine gold and buy diamonds again. Mining diamonds and gold are about the same process.
Gregg

Stan's response: Thanks Gregg. It is great to be hearing from you. Thanks for participating as you have such an amazing lifetime of experience in these fields. I endorse your books and your advice to our members.

Wisconsin Diamonds
by: Dave

You guessed it, diamonds are addictive. Here in Wisconsin we can find diamonds that were brought down by the glaciers. I have been in the hunt for over 40 years and have found over a thousand small diamonds.

One of the best ways to catch them is with a greased board. Since diamonds are not wet-able they will stick to the greased board when you run water over it. Once in a while a blue sapphire will get caught too. Sand and gravel is wet-able, so it will not stick to the grease, it just washes off. Good Luck.

Stan's response: Much appreciated Dave. That is great information.
