Geology Comments

Jul 17, 2006 (C Salo) - The Reserve Creek property is underlain by a complex assemblage of metavolcanic rocks that have been intruded by Archean-age mafic and felsic intrusive rocks, and Proterozoic-age diabase dikes. The volcanic rock assemblage is dominated by mafic volcanics that have been mapped as pillow basalts, mafic tuffs and schists. The mafic volcanics are interbedded with felsic to intermediate volcanic rocks mapped as rhyolite, agglomerate and tuff. Interflow sediments have also been reported. A number of gabbro and diorite intrusions (or coarse-grained massive mafic to intermediate flows) occur within the volcanic assemblage. The mafic intrusives generally strike parallel to the volcanic stratigraphy at an average orientation of 070. The volcanics are intruded to the south by a granitic intrusion described by Canova et al. (2006) as a massive to weakly foliated albite granite. However, near the contact with the volcanics, this intrusion has been described as a medium-grained, light brown, locally oxidized, banded and foliated quartz-feldspar gneiss containing 1% pyrite. Quartz-carbonate veins and disseminated sulphide mineralization are commonly reported in the vicinity of the Reserve Creek Occurrences. For example, Prest (1944) reported the frequent occurrence of large quartz veins south of Reserve Creek that contained much chalcopyrite and traces of molybdenite. Gold, copper and tungsten mineralization at the Reserve Creek occurrences appears to be associated with a magnetic sulphide horizon and quartz-carbonate veins that are oriented parallel to steeply-dipping shear structures that strike at approximately 070 degrees through a number of lithologies. They also appear to be located along strike with the nearby Zulapa Prospect Au, Cu occurrence. The Reserve Creek Occurrences are located within the Fort Hope-Miminiska Greenstone Belt within rocks previously identified by Stott and Corfu (1991) as being within the St. Joseph Assemblage. The type of mineralization reported in the reserve Creek Occurrences (gold associated with chalcopyrite, scheelite, magnetite, pyrite, pyrrhotite, biotite alteration), the reported occurrence of molybdenite in the area south of Reserve Creek, and the proximity of the occurrences to a felsic intrusion indicate the possibility that these occurrences may be of the alkalic porphyry type described by Rogers et al. (1995).

Mar 29, 2021 (Therese Pettigrew) - The Reserve Creek property is situated within the Uchi Subprovince of the Superior Province, a subdivision of the Canadian Shield. In the Reserve Lake area, the 10 kilometre wide greenstone belt is bounded on the north and south by tonalitic stocks. The belt is composed of east trending metavolcanic and metasedimentary rocks, believed to be isoclinally folded and metamorphosed to upper amphibolite grade metamorphism (Assessment report 20000008898).

Mineralization Comments

Jul 17, 2006 (C Salo) - Seven separate mineralization zones have been identified in the Reserve Creek Occurrences area. The characteristics of each are listed below. A and B Zones centred upon UTM Zone 16, 448950E, 5714080N (NAD27). The A and B Zones host gold mineralization that is associated with what Canova et al. (2006) describe as a sheared, silicified magnetic tuff (or magnetic sulphide horizon). This unit contains 5 to 8% disseminated magnetite and 0.5% pyrrhotite. These zones also host quartz-carbonate veinlets that are commonly boudinaged parallel to the foliation plane and mineralized with pyrite and chalcopyrite. Chlorite and weak carbonate alteration are also noted in this zone. Mason and White (1995) noted that mineralization in the magnetic sulphide horizon appears to pre-date quartz-carbonate vein mineralization, and that biotite alteration post-dates both phases of sulphide mineralization. The gold-bearing mineralization in the A and B Zones is interpreted to be located within the same stratigraphic horizon. Canova et al. (2006) have interpreted geological and geophysical data collected on the property as indicating that the magnetic tuff horizon is continuous for a strke-length of approximately 1200 m east of the currently-defined eastern limit of the A-Zone. The gold mineralized magnetic sulphide horizon hosting the A and B-Zones has been noted to pinch and swell along strike, with the defined zones representing two separate gold-bearing shoots. Horner (1989) indicated that the magnetic sulphide zone ranges from approximately 7.5 to 17 m wide in the A-Zone and 3.5 to 21 m wide in the B-Zone. Both zones strike approximately 070 and dip steeply (75 to 88 degrees) toward the north. Kidd (1982) calculated gold reserves for these zones as follows; A-Zone - 271,886 tons averaging 0.0411 ounces/ton Au; B-Zone - 129,045 tons averaging 0.0469 ounces/ton Au. These reserve estimates pre-date National Instrument 43-101 and should be considered only to represent an inferred mineral resource. C-Zone centred on UTM Zone 16, 449040E, 5714070N (NAD27): The C-Zone was described by MacLeod (1981) as a quartz vein located 220 feet east of Zone A. A number of surface samples and diamond drill core samples returned significant gold assays (e.g., surface sample result of 0.79 oz/ton over 7 inches). D-Zone at UTM Zone 16, 448920E, 5714130N (NAD27): The D-Zone has been described by MacLeod (1981) as consisting of a steeply-dipping shear in andesitic volcanics. The surface exposure contains quartz stringers mineralized with pyrite, pyrrhotite and scheelite. Significant WO3 values have been reported from surface samples (1.78% over 0.9 m) and diamond drill core (1.99% over 0.8 m). A significant gold assay of 11.8 g/t was also reported from this borehole in Hemlo Gold drillhole RC-94-1. E-Zone at UTM Zone 16, 449450E, 5714120N (NAD27): The E-Zone is described by MacLeod (1981) as scheelite mineralization along fractures and disseminated in a coarse-grained andesitic flow. Significant WO3 values of up to 0.936% were reported. Pit Zone at UTM Zone 16, 449900E, 5714260N: The Pit-Zone was identified by Canova et al (2006) and is located within a mafic metavolcanic unit that is cut by numerous 0.3 to 1 m wide quartz veins. These veins are oxidized along their margins and contain pyrite and chalcopyrite mineralization. A grab sample of massive sulphide from an old test pit in this unit assayed 1.82 g/t. New Zone at UTM Zone 16, 449050E, 5714260N (NAD27): The New Zone was also identified by Canova et al. (2006) and is described as an oxidized and silicified mafic tuff. A sample of quartz vein material from this location assayed 1.85 g/t.

Mar 29, 2021 (Therese Pettigrew) - The supracrustal rocks underlying the Reserve creek area include mafic flows and tuffs interbanded with sediments. These rocks are foliated and sheared. Gold occurs with quartz veining and sulphide mineralization within and proximal to a silicified, magnetite bearing mafic basalt unit. Aeromagnetic surveys indicate this magnetic unit extends approximately 10 kilometres across the property. The series of deep seated NW-SE and NNW-SSE lineaments that intersect the east-west trending mafic to intermediate volcanics in the proximity of Reserve Creek between First Lake and Second Lake represent regional control features to the gold mineralization patterns seen at the western most portion of the property adjacent to the Eabamet First Nations Reserve eastern boundary. These en echelon structures related to the major recumbent fold structure provide the necessary conduits for deep seated mineralizing fluid migrations. The Williamson A and B subzone ore shoots contain up to five mineralized intervals within the sulphide-magnetite-bearing mafic tuff that plunge steeply (> 075º) to the west. Subzone C is a high grade narrow quartz vein system flanking subzone A towards the south east with significant gold intercepts up to 72.6 g/t over 0.15m and, 33.9 g/t over 0.82 metres. The 2011 drill program by Slam Exploration found that quartz veining and pyrrhotite-pyrite mineralization occur in all 6 holes locally with traces of molybdenum and copper. Anomalous assay results indicate up to 0.88 g/t gold over 2.0 m. Molybdenum grades up to 0.45% molybdenum over 0.5 m and copper 0.38% over 0.5 m (Assessment report 20000008898).
