The ore minerals are pyrite, sphalerite, chalcopyrite, galena, and minor tetrahedrite
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.

Stage 4 is marked by a mineral assemblage composed of quartz + antimony-lead-silver sulfosalt minerals (Figure 4(r)) that prevailingly include boulangerite and jamesonite, as well as minor bournonite, tetrahedrite
, and andorite.
Prospecting in 2015 focussed on a highly siliceous gossanous andesite outcrop with azurite/malachite oxidation and possible tetrahedrite

Concerning mineralogy, the ore deposits contain mainly pyrite, although there are also sphalerite, tetrahedrite
, arsenopyrite and pyrrhotite.
Sulphosalt group compounds such as chalcostibite (CuSb[S.sub.2]), famatinite ([Cu.sub.3]Sb[S.sub.4]), and tetrahedrite
([Cu.sub.12][Sb.sub.4][S.sub.13]) are part of a relatively new class of material containing antimony.
Sulfide mineralization in the form of chalcopyrite, tetrahedrite
and pyrite is noticed along shear zones and in the vicinity of thick marbalized beds and silicified alteration zones within the Shamran / Teru volcanics.
, argentite, pyrrhotite and native gold occurred sporadically and sparingly.
