Reference information

Comments Part of the Kassiteres-Sappes multi-centered porphyry-epithermal system, a deeply eroded Tertiary volcanic edifice having hydrothermal features that suggest that the area is a multi-centered porphyry/epithermal system. Subeconomic porphyry prospect associated with a 0.8 by 1.0 km outcrop of microdiorite in the Koryfes Hill area about 1.5 km S of the St. Demetrios prospect and about 3 km NE of the St. Barabra epithermal system K-Na-silicate alteration; stockwork veining, replacement and disseminated pyrite, chalcopyrite, minor pyrrhotite. High-sulfidation 20-m-thick high sulfidation silicic cap. Surface samples up to 700 ppm Cu and 0.5 g/t Au. Propylitic alteration halo. High-grade stage II veins: up to 0.43% Cu, 0.7% Pb, 1.23% Zn, and 190 ppm Mo.
