Ta, very informative! The goldest bits don't shatter and you can scrape off and are gold on all sides. now rattling around the shed to see if I can improvise a rock crusher!
hi,
I live on the edge of barossa gold fields and disturbed some rocks. Certainly looks like gold flecks in the sunlight, even more so than here. Fools gold? Presumably you need more of a seem than flecks to be worth the effort of extracting?
