The dominant sulfide minerals include sphalerite and galena along with
argentite and native silver, and they occur as disseminations, bands, or zones of massive sulfide.
The mineralisation occurs as Co-Fe-Ni Arsenides,
argentite, niccolite and native Silver.
Which metal is obtained from
argentite? Andre Rieu - see Question 7 10.
Tennantite, tetrahedrite,
argentite, pyrrhotite and native gold occurred sporadically and sparingly.
The deposits contain the important silver ore minerals,
argentite and pyrargyrite, as well as argentiferous galena and antimonial silver minerals, the latter in their deeper portions.
Pedrazzini to the Egleston Collection at the Columbia School of Mines, where there are also a number of other specimens of polybasite and stephanite, as well as a remarkable specimen representing the transition of an
argentite crystal into cerargyrite and a fine embolite.
From here, Prospect Avenue,
Argentite Street, and Haileybury Road (renamed Lang Street in 1911) radiated out to the west, northwest, and north respectively.
MMDC notes that in Vaticano Poniente, "The remarkable coincidence of the presence of iron concentration, conductive minerals at depth and a broad alteration zone at surface, localised in the Morelos formation (hosting the mineralisation in the Nukay district) in a mountain called Cerro Colorado (red stained mountain), make these anomalies a worldclass target for exploration." To the extreme south of the area under consideration, MMDC's Agau claim includes the old Poder de Dios mine of narrow epithermal bonanza type veins with
argentite and gold.
Mineralization consists not only of disseminated and banded massive sulphides, but also of vein style polymetallic occurrences consisting of pyrite, sphalerite, galena, chalcopyrite, tetrahedrite,
argentite, electrum, bornite and ruby silver.
