GUID (UUID V4):

The Cerro Kiosko deposit consists of a 1.25-to 22-m-thick, ~1,100-m-long, and ~400-m-deep tabular quartz-sulfide vein swarm hosted by silicic-altered basaltic andesites and andesites of the upper unit, and also includes sulfide disseminations. The vein swarm is composed of stringers and massive sulfide lodes largely controlled by NW-striking normal faults that dip ~60° to the southwest. Reserves: 2.8 Mt at 2.2 g/t Au, 4.7 g/t Ag, 0.6% Cu
At Cerro Kiosko, an outer extensive domain of moderate-intensity propylitic alteration grades inward and downward to narrower domains of phyllic and intermediate argillic alteration. Propylitic alteration caused chlorite to replace clinopyroxenes and the glassy matrix, and produced thin veinlets of chlorite and albite alteration of plagioclase. Phyllic alteration caused fine-grained muscovite to replace plagioclase and parts of the groundmass. In intermediate argillic zones, fine-grained quartz and kaolinite pervasively altered the volcanic rocks so that no original textural features are recognizable. Fine-grained pyrite dissemination increased markedly (>50% modal) along with the degree of silicic and kaolinite alteration.
Cu (± Ag ± Au) mineralization produced 0.5-to ~30-cm-thick massive sulfide stage 1 veins and lodes within strongly quartz altered host rocks. The thickest veins have multiple internal growth bands. Stage 1 caused hydrofracturing of the previously altered host rocks and cementation of the fragments by pyrite. Although not common, quartz fragments are locally cemented by fahlore. A transitional shallow porphyry–deep high-sulfidation epithermal environment for the deposition of ores.
