The mineralogy of the milled Haib feed revealed that 98.5% of the total copper content occurred as chalcopyrite, 1% as bornite, and less than 0.5% as chalcocite, covellite, malachite and chrysocolla.

Copper sulphides such as CuS (covellite), [Cu.sub.1.75]S (anilite), [Cu.sub.1.8]S (digenite), [Cu.sub.1.95]S (djurlite), and [Cu.sub.2]S are of great interest as they can be applied in energy storage, owing to their variations in stoichiometric compositions, complex structures, and valence states [11].

* Phase 2: Stronger and later overprinting mineralization events are also evident in most of the new drill holes, including widespread garnet-bearing skarns containing clots, veins, and disseminations of covellite, native copper, and bornite, with local formation of secondary chalcocite.

We also investigated the XRD pattern for CuS powder synthesized by the same starting solution of the SILAR method, and all diffraction peaks were assigned to covellite CuS crystal phase (see our supporting information, Figure S4).

Several additional surface-reaching minerals were identified that did not contribute to the golden sheen: pyrite, baryte, covellite, zircon, muscovite, albite and K-feldspar.
