All - wondering if any of you out there have any experience with using either of these detectors inside hardrock mines or on hardrock ore, veins, etc. I recently purchased both of these detectors and I am interested in the discrimination on gold in an old hardrock mine area. I have found that the Equinox will find arsenopyrite very nicely in samples, and I have found the GM does not respond at all to large chunks of pyrite in samples I have. However I am interested in discrimination on gold in rock and veins where there are arsenopyrite, pyrite, large amounts of chalcopyrite, lead, zinc, etc. Anyone with any experiece with the Equinox in prospecting mode sounding off on any of these minerals (besides gold)? Anyone with experience with the GM 1000 on any of these minerals in Gold non-ferrous mode? Since some of the veins have extensive pyrite, chalcopyrite and base metals, I was hoping I could discriminate gold from the other elements in some of the hardrock areas and tailings I've come across in my wanderings. Thanks in advance for sharing any thoughts around these detectors on minerals like that in hard rock and how they would likely respond to them.
