[QUOTE="XLOOX, post: 668408, member: 16174"] Arsenic(As) is extremely closely associated with iron pyrites often at a level 10,000x the gold level & if it is present that will overwhelm the gold signal for XRF. No harm in trying though but wont know for sure if the reading is a false positive or not until do a fire assay. Also it is all a bit moot as Goldfreak wont be looking to start a mine based on 2 sugarcube sized samples :), I think he is just curious as to what his nice specimens contain. [/QUOTE]
