Apr 21, 2010 (A Wilson) - Both the North and 2000 deposits are characterized by Cu-(Ni)-PGE-rich 'sharp-walled'veins and chalcopyrite-rich 'breccia' veins containing silicate inclusions, in addition to domains of poorly connected stringers and disseminated PGE-bearing sulphides and are typical of Sudbury 'hybrid'-styles of mineralization. Sharp-walled massive veins appear to cross-cut the 'breccia' veins, stringers and disseminated sulphides. Timing relationships between 'breccia' veins, stringers and disseminated sulphides are poorly understood. The sulphide breccia veins of the North Deposit typically strike sub-parallel to the length of the offset, whereas discontinuous extensional jogs filled with chalcopyrite-rich sulphide are oriented oblique to the offset (roughly north-south). Chalcopyrite rich sulphide masses and veins up to 15 ft wide have been intersected and occur as both extensional veins and breccia veins with chloritized silicate clasts. Mineral envelopes of vein concentrations occur at variable strike (northeast to northwest) and variable dip angles (10 to 90º). Vein shapes vary from straight symmetrically tipped veins, stepped kinked bayonet and T-shaped sets, very irregular embayed (ragged) outlines with local piercement tips, to veins which have one straight/sharp contact with the other embayed and ragged. Weak blebby to disseminated chalcopyrite mineralization is not uncommon, but is confined to within a few inches of the vein contacts.
Apr 21, 2010 (A Wilson) - Fine-grained chlorite, amphibole and epidote alteration controlled by small scale faults and localized shear deformation also appears to control the vein mineralization. The development of mafic mineral alteration halos around sulphide veining is ubiquitous at the North Deposit.
