It’s accepted knowledge that wet methods will recover more fine gold than dry methods and processing the gravel as a whole will get more gold than only using a metal detector. The question is how much more?
A retired gold prospector spent hours digging up his fortune in the northern goldfields near Kambalda, Western Australia, after finding the target with his metal detector.
Rocks and minerals associated with clay seam gold deposits in southern Oregon are often in sedimentary rock units at least partially metamorphosed into argillite. They are also associated with mafic volcanic rocks, basalts and gabbro that...
