Dec 07, 2005 (B Nelson) - The oldest rocks in the vicinity of the Hard Rock Mine are tuff and volcanic breccia, which, with peridotite and hornblende diorite, form a low but conspicuous ridge along the south edge of the claim group. The sedimentary rocks are the more interesting from the standpoint of mine geology; it is within them and along their contact with the quartz-albite porphyry that several important orebodies have been found. They consist mainly of greywacke and iron formation, but interbeds of slate occur locally and a continuous band of conglomerate has been traced across the property. All of the rock formations in the vicinity of the mine have been intensely folded. Three distinct orebody types have been recognized: 1). Quartz veins and mineralized zones occur within and along the contacts of the albite porphyry and within greywacke and lean iron formation. Gold occurs in both altered wall rocks and veins, and is closely associated with sulphides. 2). Irregular, massive lenses of sulphides and quartz occur in a folded series of greywacke and iron formation. Veins are usually barren of gold mineralization except where they contain sulphides. Ore is locally banded. 3). Numerous thin, gold-bearing quartz stringers occur along shear fractures in zones of faulting, folding and shearing at the contact with wacke and albite porphyry. Gold concentrations were relatively lower than in the first two types. The F Zone was the most spectacular zone, accounting for an orebody of some 10,000,000 tons of 0.15 oz/ton Au.
Aug 11, 2014 (Therese Pettigrew) - The local geological setting of the Hardrock deposit is represented by the southern sedimentary unit of the Beardmore-Geraldton Belt. The southern sedimentary unit in the Geraldton area is characterized by multiple horizons of magnetite-rich chert banded iron formation within a thick sequence of interlayered sandstone-argillite and minor polymictic conglomerate. The sequence is intruded by medium- to coarse-grained diorite sills and feldspar-quartz porphyry dykes, which, together with the sedimentary rocks are folded by tight to isoclinal, regional F2 folds. Most mineralized occurrences in the Hardrock deposit area lie in a zone of deformation to the immediate north of, and genetically linked to, the Tombill-Bankfield Deformation Zone. Gold deposits in the Hardrock deposit area are examples of epigenetic non-stratiform banded iron-formation-hosted gold deposits (Brousseau et al., 2013).

Dec 07, 2005 (B Nelson) - Serpentinized peridotite and hornblende diorite occur together as a folded lens or sill-like mass along the north flank of the tuff breccia horizon in the vicinity of No. 1 shaft. Quartz-albite porphyry forms a large, highly irregular, contorted mass and for the most part conforms to the highly complex pattern of the enclosing sediments. Altered quartz diorite has been found in several places cutting the greywackes and iron formation as narrow dykes and sill-like bodies too small to be shown on the map. Narrow dykes of both quartz and olivine diabase, which cut all the other rock formations, have been found in several places in the underground workings.

Apr 24, 2014 (B Nelson) - Sulphides include pyrite (80%), arsenopyrite (15%), pyrrhotite, sphalerite, chalcopyrite, leucopyrite, galena, gold and cubanite. Non-metallic minerals recognized include ankerite, calcite, scheelite, tourmaline and graphite. Iron oxides occur in many places. Gold production totalled 269,081 oz. Silver production totalled 9,009 oz. Assays: 18.54 g/t Au across 25.5 m in hole MM552 and 2.90 g/t Au across 27.3 m in hole MM538 in the main pit area and 1.30 g/t Au across 57.0 m and 29.20 g/t Au across 11.0 m in hole MM571 and 80.57 g/t Au across 4.5 m in hole MM573 in the North Wall Zone.
Aug 11, 2014 (Therese Pettigrew) - Gold mineralization generally occurs in association with subvertical structures associated with quartz veins or stringers, minor to semi-massive sulphides (associated with replacement zones in BIF), weak to moderate carbonate and weak to strong sericite alteration. The or zones rake shallowly towards the west in the vicinity of the Hard Rock, MacLeod-Cockshutt and Mosher Mines (15-30° W) and slightly more steeply towards the west at the Little Long Lac Mine (50-60° W), indicative of a strong structural control that post-dates the tight folding of the primary units. There is also local control as a result of lithological controls, with gold-bearing zones preferentially forming where subvertical structures have crossed favourable environments, including the BIF and areas around the contact of the Hard Rock Porphyry and the sedimentary rocks it intrudes. The structurally controlled, high grade veins spatially related to the Hard Rock Porphyry are similar to quartz-carbonate-sericite veins that host gold in many gold camps in Ontario. The veins related to the Hard Rock Porphyry do not host significant tonnages of ore from past production, despite their locally high grades. The turbidite-associated mineralization is typically characterized by narrow, often sheeted, mm-cm scale veins with attendant by highly variable degrees of carbonate-sericite-pyrite alteration. This style of mineralization forms wide, low grade zones. The iron-formation hosted mineralization is similar to that in Archean-age gold mines elsewhere in Ontario (Musselwhite and Dona Lake Mines). This mineralization is typically in the form of sulphidized zones on a cm-m scale associated with minor quartz veins that transect iron-formation beds (Armstrong et al., 2010).
Dec 07, 2005 (B Nelson) - Some of the quartz stringers are not accompanied by any visible alteration of the wall rocks, but most of them, and in particular those that are gold bearing, are bordered by buff-colored salvages of sericitized and carbonatized greywacke. The selvages may extend for as much as eight inches outward from the wall of a stringer not more than a quarter of an inch in thickness, and where several stringers occur along closely spaced, parallel fractures, altered zones several feet in width are common.
