11. The economic minerals associated with this deposit are predominantly pentlandite and chalcopyrite . 12. These minerals are accompanied by sphalerite, pyrite and chalcopyrite . 13. It is a tetrahedrally bonded semiconductor, with the chalcopyrite crystal structure. 14. Valleriite occurs in dunites and chromitites replacing chalcopyrite in Cyprus. 15. Other products from the mine are sphalerite, chalcopyrite , and galena. 16. Chalcopyrite is rarely found in association with native copper.17. Chalcopyrite is concentrated in this environment via fluid transport.18. Thus, manto deposits need not be the weathered equivalents of primary chalcopyrite . 19. Gangue minerals include common quartz and calcite, and minor barite and chalcopyrite . 20. Pyrite with chalcopyrite and gold occupies quartz veins as blebs and small veins.
