Geological maps of the Coleman Mine (A) and Creighton Mine (B) areas, highlighting the relationship between the footwall lithologies and SIC melt sheet. Discontinuous zones of Sudbury Breccia are ubiquitous throughout the footwall and are not shown. The outlines of the Cu-Ni-PGE ore zones have been projected to the surface. At Creighton, the distal sample sites Old Creighton Town and South Pump Lake are also shown (modified after Ames et al. 2008). Ore bodies are outlined in red and projected to surface. Faults are depicted by dashed black lines.

(A) A typical Sudbury breccia outcrop from close to the Creighton Mine exhibiting a dark grey, very fine-grained matrix hosting rounded clasts of locally derived host lithologies. (B) A sharp-walled sulfide vein from the Fraser Mine (adjacent to the Coleman Mine) in the North Range. The vein transitions from type-1 (chalcopyrite-dominant) to type-2 (bornite-dominant). The thin, dark grey-green alteration selvage can be seen adjacent to the vein. The host lithology is felsic gneiss with Sudbury Breccia (yellow arrow). Photo (B) courtesy of Dave Richardson.
