Sphalerite, Calcite, Dolomite

The Newfoundland Zinc  Mine has been closed for many years. It was a high grade zinc mine with very little galena, pyrite or other contaminants in the ore and so was relatively easy to mill and produced a very desirable concentrate. Here is a plate of, sphalerite that is largely covered by well-formed dolomite and calcite crystals. Collected back in 1979 or 1980. Looks great!
