Further Info:

 The principal metallic minerals within the orebody are galena, sphalerite, pyrite, chalcopyrite, malachite, auzurite, chalcocite, marcasite, tennantite, prousite, pearceite and acanthite. Pyrite and marcasite are closely associated and occur as dull, metallic, brass-yellow, fine grained intergrowths of a colloform or concretionary texture. the galena, sphalerite, chalcopyrite and other sulphides are closely associated with the pyrite and marcasite and, in most cases, are intergrown with them. Stalactitic and botryoidal masses of pyrite and marcasite fill late fractures in the sulphide body. Galena occurs as fine grained masses, in brecciated pods, fracture- and seam-fillings and as fine disseminations. Sphalerite is light to dark brown and is almost always intergrown with galena. Chalcopyrite occurs as pure blebs, masses, stringers and irregular patches. Tennanite is lead grey and commonly intergrown with chalcopyrite, also occurring as irregular masses and small discontinuous seams. The high silver-bearing sulphosalts prousite and pearceite occur as disseminated grains and small masses within vugs and crushed breccia zones. Malachite and auzurite are rare and usually occur as coatings on other sulphide minerals.
