摘要

Set in ca. 74 km(2) of rugged terrain close to the Zambezi Escarpment, the Snake's Head Platinum Project covers the northeastern half of the Musengezi Subchamber in the northern part of the Great Dyke. Here, the linear Great Dyke straddles the boundary between the Zimbabwe craton and the late Archaean Migmatitic Gneiss Terrain and is folded into a prominent S-shape adjacent to the Neoproterozoic-Phanerozoic Zambezi orogenic belt. Snake's Head contains the northernmost remnant of the Great Dyke's P1 Pyroxenite Layer, which hosts the economically-important, stratabound, PGE-rich Main Sulphide Zone (MSZ), as well as the lower grade (but petrogenetically very similar) Lower Sulphide Zone (LSZ), together containing one of the Great Dyke's last undeveloped platinum resources (>80 m oz).
