pyrite is negative ion to gold, some pyrite bearing rivers are easier to detect gold than others. I say do some research to where you think a gold bearing river maybe, if in history it was not dredged like most of shoalhaven go for gold. Dont be shy to walk the distance, and when you find it DO NOT SELL IT
