We recovered A LOT of gold and silver from these black sand concentrates that didn't have any visible gold or silver in them. This was a sample of concentrates off one of our MBMM shaker tables that a customer sent up for us to test our smelting setup on and WOW were we surprised with the resulting button. Just goes to show that smelting/assaying black sands may be worth it especially if they come from rich gold ore. Don't throw anything away until you know its actually junk.
