Porphyry copper-gold deposit, mined since 1997.

The mineralization is believed to have formed in a vertical hydrothermal breccia body within a complex of monzonitic intrusions. It now occurs in two segments which were formerly contiguous but are now separated by the steeply southwest-dipping Brown Wall fault. The upper hanging wall portion was mined in the Wight pit (2005-2009). The deeper portion was dropped down slightly and offset to the northwest, and is known as the Martel zone, the top of which was exposed in the bottom of the final Wight pit. Mineralization generally begins immediately after the fault, and consists of chalcopyrite and bornite disseminated in a polylithic breccia matrix, in fine to coarse infill between clasts or in veins. Late to post-mineral monzonitic dikes cut the breccia, the largest being 10-14 metres thick, obliquely bisecting the Martel zone, otherwise internal dilution by dikes is limited.

The Martel zone measures approximately 130 metres long, 170 metres high, and 140 metres wide, perpendicular to the Brown Wall fault plane. Along its northeastern fringe, the Martel zone gives way to monzonitic wall rock and dikes. The easternmost body of mineralization intersected in this drilling is the Green zone which is hosted in a distinct style of breccia and is intermittent but can be very high grade. The Martel zone is open in all directions except to the southwest where the Brown Wall fault cuts-off the zone.
