I know your out there, Weekend prospectors and rockhounds , who, Like myself have a Passion to generate Wealth, however small, from the many creeks ,Streams and Rivers that crisscross our country. In My case , it's the small placer deposits, like gold Flake and semi precious stones that are occasionally found along the Glacial Till in Central Ohio. Pickings around here are slim, and i do get a few odd stares from people who see me running my Metal detector along a creekbed, or sifting through gravel, but i have fun anyway.If I had my way, I'd find a nice Claim to work in northern California or Alaska, But life being what it is, I'll just have to Settle for The Buckeye State........at least for now. Just so i Don't feel like a total Failure at Prospecting , I've Recently began buying Concentrates from different Vendors on Ebay.Like everything else on Ebay, Some cons are good, some are rip offs and others exceed expectations. My experience so far leads me to believe that the best Cons are sold by Hardrock,or to put it another way Working Miners. People who not only sell there product, but make a living from there product as well. I recently Bought a Pound of Gold concentrate from GPAA ,  that was just super saturated with Gold Flake and a few nice pickers. A nice mix of Gravel and Black Magnetic Sand. I Bought a pound for 30 Bucks and got at least a Gram+, the only drawback is you really have to pan it a few times to get it all, but it's worth it. So far, thats the best I've seen, but being adventurous, I've decided to try Different Vendors. I'll update this Guide as I go along. I won't list the bad sellers, for liability concerns, Just the ones who , In my humble opinion, are worth your hard earned cash. If anyone who reads this wants to recommend there Favorite Vendor, Please feel free to Email Me. Thanks.
