Photos of El Cura drillcore: J: EC066 pyrite lens in contact with black shales. Sulfide assemblage is dominated by pyrite, sphalerite, and chalcopyrite. K: EC067 massive sulfide characterized by high proportions of chalcopyrite in both banded and patchy textures. Local bands of galena and sphalerite are also observed. L: EC068 massive sulfide with chalcopyrite in fractures and veinlets.
