Sporadic mineralization over an 1800 by 800 m area in adamellite and microadamellite of the Balluchulish igneous complex. Explored by the British Geological Survey in the 1970s by IP, core, and outcrop sampling. Subeconomic. Maximum concentrations in core samples: 264 ppm Cu, 501 ppm Mo; higher grades in selected outcrop samples. No K alteration; well-developed phyllic alteration; no typical porphyry copper zonation; low-grade, low salinity fluid inclusion (that is, atypical of porphyry).
