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.
The presence of rare sulfides (i.e., argentite, covellite, and cinnabar) and abundant pyrite may be fully explained by the acid leaching of rock particles followed by sulfide precipitation from leachates; that is, rock aerosols may serve as a source for chalcophile metals and iron.
