Crossword-Solution: CUPRITE 7 letters, 3 clues 🏆 scrabble score: 11

The associated minerals are, here, _cuprite_ or yellow copper, green _malachite_ or carbonate of copper, _mispickel_ or arsenical pyrites, _zinc blende, sesquioxyde of iron_, rich in gold, and also frequent "sights" or visible masses of gold itself.

The minerals associated with the quartz in this vein, especially the cuprite and mispickel, are found most abundantly upon the foot-wall side, or underside of the quartz itself.

The oxide group of minerals--including the copper carbonates, azurite and malachite; the silicate, chrysocolla; the oxide, cuprite; the sulphates, chalcanthite and brochantite; and some native copper associated with these minerals--probably supplies another 5 per cent.

Note: Copper is the only metal which occurs native abundantly in large masses; it is found also in various ores, of which the most important are chalcopyrite, chalcocite, cuprite, and malachite.
