Found this cool magnet while looking for other stuff. Thought I would throw it out there. Cheesy plunge magnets for black sand and what not always drove me nuts. But this is well built and for its size has impressive power 60lb pull and 17lb shear. Turn the switch to release the magnetic pull. Very cool.
Caught some info online today about an inventor named ..............He spoke of a patented a process that treated black sand concentrates with gamma rays. this was said to have greatly increased recoverable gold.
this ties in to a hypothosis i have abt "growing" gold.
does anyone know anything about this process?
Steve i tried to load this in the accessories forum but it is archived--- would you mind placing it in the correct place for me,,,thx paul
One of these is a little better than the other----pretty simple

Well....not exactly new, but new to me.
My wife was thrift shopping yesterday and picked me up an old used Estwing 12" steel gold pan as a surprise gift. I was happy that she recognized it and bought it for me and I think its pretty a cool pan. I normally use a green plastic pan but I think it will be cool to swirl a metal pan.
She wants to see it in action. She "suggested" I go pour some gold into some yard dirt and pan it out and see how I liked it. I "suggested" that we go out Sunday morning to a local spot and see how it works on fresh gold. She then suggested we wait and do a road trip and make it a long weekend thing......oooh......better and better....
I have no idea how it will turn out but I'll let you know.
Last night I read a very interesting (IMO) article by Chris Ralph in the June, 2019 issue of the ICMJ (https://www.icmj.com/) titled "How Long Does It Take to Find and Recover an Ounce of Gold". There are a lot of caveats Chris lists, which makes it dangerous for me to summarize what was written. Further, there is a fine line between showing results from a magazine/journal which needs money to stay afloat and requiring interested parties to simply pay for a subscription. IMO, anyone halfway serious about searching for native gold (and there's more there than just gold) should be a subscriber. Most importantly, his estimates certainly depend upon the ground you are covering -- this should be obvious to everyone and I hope simply mentioning it will squelch any attempt to quibble at his results. Basically there is a lot of uncertainty around Chris's numbers, which he is well aware of, but it's still interesting to hear from an expert who has used all of these methods countless times. I was surprised at some of his estimates. In order longest (least efficient) to shortest:
Panning: 42 hrs,
Metal Detecting: 40 hrs,
Sluicing/Highbanking: 30 hrs,
Dry Washing: 30 hrs,
Dredging: 20 hrs,
Hard Rock Mining: 8 hrs.
I think it's worth emphasizing that this is a time efficiency, not a cost efficiency. Panning is clearly the least expensive with hard rock mining by far the most. Chris also points out that the leadup time/research/preparation & cost are vastly different -- hard rock mining being the obvious extreme.
