Summary:
Scottie Gold Mine Project Area
The Scottie Gold Mine deposit comprises the Summit Lake vein system, including the L, M, N, O, P and Wolf zones, hosted within the Unuk River andesite. Veins occur in shear structures, extending over 300 m along strike and up to 400 m vertically (e.g., M Zone), within a 400 m wide corridor. Individual veins range from 2 m to locally 7 m wide. Gold-rich shoots typically plunge steeply northwest. Less strained extensional veins trend east–west and are interpreted as splays from NE–SW shear structures.
Both shear and extensional veins contain variable sulphide mineralization, from disseminated sulphides to massive lenses dominated by pyrrhotite and pyrite, with lesser arsenopyrite, chalcopyrite, galena, sphalerite, tetrahedrite, and gold. Alteration halos consist mainly of chlorite and silica, grading outward to carbonate, sericite, and minor epidote. Similar mineralization occurs in nearby targets including the C, D, E, Dave, 6 oz., Hura, Lone Wolf, and Scottie’s Rib zones.
Domino
The Domino target hosts narrow (<1 m) shear veins similar to Summit Lake but developed within intermediate to felsic volcaniclastics. Three steep, NE-striking shear structures were drill tested in 2020. Mineralization and alteration define a footprint of ~800 m strike, >300 m vertical extent, and 500 m width. Gold and silver are associated with pyrrhotite, pyrite, chalcopyrite, molybdenite, sphalerite, and galena, with silica–sericite–chlorite alteration. Related targets include Moondance, Gloria, and Mystic.
Blueberry Contact
The Blueberry Contact Zone is defined by a near-vertical andesite–siltstone contact and multiple NW-dipping veins, offset by an E–W dextral fault. The zone hosts Au–Ag-bearing sulphide–carbonate–quartz veins with sericite–chlorite alteration. Mineralogy includes pyrite, pyrrhotite, sphalerite, molybdenite, galena, and arsenopyrite. Key zones include Road, Blueberry, Lemoffe, Fifi, Gulley, and E zones.
The Road Zone represents the most consistent gold mineralization, with visible gold locally observed in drill core. Veins are dominated by pyrrhotite–pyrite–quartz–carbonate with strong sericite–chlorite alteration.
The Blueberry Vein Zone comprises four parallel structures within a 60–130 m wide corridor. Blueberry Vein 2 is the main structure, a massive sulphide vein up to 2 m true thickness. The Fifi and Lemoffe zones host multiple NW-dipping massive sulphide veins over widths of 70 m and 45 m, respectively.
The Gulley Zone contains Au-bearing quartz–carbonate–sulphide veins along the contact, while the E Zone hosts Au–Ag sulphide mineralization and the Serac Vein, a ~2 m wide massive pyrrhotite-dominant structure with elevated base metals.
Bend
The Bend Vein is a quartz–carbonate–chlorite–sulphide shear vein averaging 1.7 m true width, associated with the ENE-trending Bend Fault. It strikes 060° and dips 45–70° NW, with high-grade gold and silver in a west-plunging shoot. Sulphides include pyrite, pyrrhotite, chalcopyrite, sphalerite, galena, molybdenite, and cobaltite. The vein has been traced for 110 m along strike and 80 m vertically.
Stockwork
The Stockwork Zone comprises a 750 × 500 m area of quartz–sericite–pyrite alteration with a quartz vein stockwork, containing pyrrhotite, pyrite, trace molybdenite and chalcopyrite, and anomalous gold. Elevated Au and Mo suggest porphyry-style mineralization.
C and D Zones
The C and D Zones host shear and extensional veins similar to the Scottie Gold Mine, within the Unuk River andesite. C Zone veins extend over 270 m strike and 150 m vertically, while the D Zone is more limited. Mineralization includes pyrrhotite–pyrite with lesser base metals and gold, within quartz–carbonate gangue and silica–chlorite–sericite alteration.
Mineralization
Gold mineralization is interpreted as intrusion-related. High grades correlate with increased sulphide content, while base metals and silver form broader but generally weaker halos in gold-rich areas. Veins occur as en échelon or sheeted shear veins and less strained extensional veins, likely sourced from the Texas Creek intrusions, which are linked to regional deposits such as Premier-Dilworth, KSM, and Brucejack.
Over 30 gold ± silver vein sets have been identified, dominated by gold-rich shear veins and polymetallic extensional veins. The most advanced targets are Scottie Gold Mine, Domino, Blueberry, and Bend. Fine-grained diagenetic pyrite occurs in Stuhini argillite gossans but carries insignificant precious or base metal values.
Deposit Types
Mineralization at the Scottie Gold Mine Property consists of sulphide-rich shear veins and extensional veins that are part of the intrusion-related gold deposit type. These deposits are transitional between deeper porphyry and shallower epithermal deposits and are sometimes referred to as mesothermal veins.
