Snake, You would see lots of metal (sulfides) of different colors in many core boxes. Chalcopyrite (the copper sulfide ) would be greenish-yellow metallic, sphalerite (the zinc sulfide) would be brown resin like metallic, pyrite (iron sulfide) would be pale yellow metallic and pyrrhotite (iron sulfide) would be white-gray metallic. You could do a calculation of greenish-yellow and brown versus total sulfide to give you a %. Of that %, we know that 25% of the greenish (chalcopyrite CuFeS2)is copper and at least 25% of the brownish is zinc. So if the core has 10% greenish and 10% brownish, there should be VERY ROUGHLY 2.5% copper and 2.5% zinc. Of course, I would not use that in a news release- it's much better to have it assayed. And being humans, we always tend to visually over-estimate the good stuff. At least you would see lots of metal and be happy. VMS core makes for nice props at "dog and pony" shows.
