sam, Having seen the rich VMS drill cores from DFR and DRZ, I can say "white viens" are not nickel sulfides. ValuePro

Sam: Your asking the wrong person, but, the white vein is more than likely a quartz vein and the qold flecks may be pyrite (fools gold)... Fools gold can be verified by its appearance...It's fairly smooth and flakey and has harsh edges, while gold is soft, rounded and pitted (at least the real stuff that I have seen was)... The proper persons to ask may be Vaughn, Walt or Feline, Terry Crebs who post on this thread...Another fellow to ask may be George Tromp who posts on this thread and now his own....

Visible Gold _ as Ed said gold is very soft so the field test to distinguish gold from other fools gold (usually tarnished pyrite or chalcopyrite) is to take a pin or small knife. If you can stick the pin in or scratch it, its probably gold. Depending what impurities are in the gold it can range in colour from pale yellow (butter colour) to bright yellow to a reddish yellow. The white veins you talk of will either be quartz or calcite. Most geologists carry a little bottle of diluted hydrocloric acid to field test between the two. Quartz is silica based so nothing happens but calcite fisses and disolves. Alot of your sulphides (on a fresh surface) look metalic. Most geos carry a magnet to test for pyrrhotite which is magnetic in most cases. The brassy yellow metalic stuff you are seeing is probably chalcopyrite.possibly mixed with a nickle sulphide. Hope this helps regards Walt
