Location and access

The Boulder Mountain mineral claims are located in the Similkameen Mining Division north-northwest of Tulameen. Recent logging within the mountain pine beetle affected area has improved access across parts of the property.

Regional geology

The property is underlain by andesitic to locally dacitic flows and pyroclastic rocks of the Upper Triassic Nicola Group. These rocks are unconformably overlain by felsic to intermediate volcanic rocks of the Middle to Upper Cretaceous Spences Bridge Group, which are prospective for epithermal-style gold mineralization.

Mineralization highlights

South Copper MINFILE 092HNE122

  • 1–3 m thick sulphide-rich horizon with chalcopyrite-pyrite stringers and quartz-carbonate veining.
  • Mineralization mapped over approximately 150 m.

  • Polymetallic vein showing with pyrite-chalcopyrite massive sulphide bands.
  • Massive sulphide bands reportedly contain up to 30% chalcopyrite.
  • Historic results include 1.25% Cu and 7.5 g/t Ag.
  • Additional zinc and lead values indicate broader polymetallic potential.

North Copper MINFILE 092HNE007

  • Subvolcanic, vein-hosted mineralization in chlorite schist and andesite.
  • Chalcopyrite-bearing quartz veins occur within the showing area.
  • Historic grab samples include approximately 2.94% Cu and 38.7 g/t Ag.
  • Associated zinc values are reported up to approximately 0.8% Zn.

History and exploration potential

The Boulder Mountain copper system was first explored in 1901. Gold River Mines Ltd. later completed trenching and drilled 9 holes totaling 894 m during 1972 and 1973. Subsequent work has included trenching, mapping and sampling by multiple operators. The property has exploration potential for stratiform copper-silver horizons, polymetallic veins, subvolcanic Cu-Ag-Au mineralization and epithermal-style gold targets.

Location and access

The property is accessed from Princeton via Highway 3 and the Stemwinder, Jans Creek and Upper Jans Creek forest service road system. Access within the property is supported by maintained and unmaintained gravel logging roads.

Regional geology

The property lies on the southern margin of the Middle Jurassic Osprey batholith and straddles alkali feldspar granite and granodioritic intrusive phases. Mineralization includes garnet-clinopyroxene-magnetite skarn-altered diorite, disseminated to semi-massive sulphides and altered dioritic rock carrying chalcopyrite-pyrite-arsenopyrite mineralization.

Mineralization highlights

Max Showing and Rock Sampling

  • Garnet-clinopyroxene-magnetite skarn-altered diorite with chalcopyrite, pyrrhotite, arsenopyrite and malachite.
  • Sample 994R002 from the Max showing returned 4,124 ppm Cu and 13 ppm Ag.
  • Sample 994R004 returned 230 ppb Au and 897 ppm Cu from altered diorite.
  • Sample 994R005 returned 139 ppb Au and 1,272 ppm Cu from silicified rock with pyrite, arsenopyrite and chalcopyrite.

2022 Soil and Magnetic Work

  • 788 soil samples were collected across two gridded surveys with 50 m line spacing and 25 m sample spacing.
  • A western-grid gold anomaly measures approximately 150 m by 200 m and remains open to the west.
  • Two coincident copper-gold soil highs returned 47 ppb Au and 187 ppm Cu.
  • Ground magnetics outlined four elevated magnetic response areas, including the Max showing area.

2021 Airborne Magnetic Survey

  • High-resolution helicopter-borne magnetic gradiometer survey flown over 28.3 km².
  • Survey included 338 line-km with 100 m survey line spacing and 500 m tie-line spacing.
  • Three magnetic regions were identified within the McNulty block.
  • Four potential areas of interest were outlined: PT1, PT2, PT3 and PT4.

Exploration Model

  • Exploration is focused on copper-gold skarn and porphyry copper-gold potential.
  • Magnetic surveying supports targeting of magnetite and pyrrhotite-bearing mineralized systems.
  • Recent logging and road access may expose additional outcrop for prospecting and rock sampling.
  • Recommended follow-up includes grid extension, geological mapping and additional rock sampling.

Exploration potential

McNulty presents a combination of skarn-altered intrusive rocks, copper-gold-arsenic rock geochemistry, gold and copper soil anomalies, and airborne and ground magnetic targets. The property remains prospective for copper-gold skarn and porphyry-style mineralization, with follow-up recommended on the western grid and magnetic target areas.

Location and access

The property can be accessed from Princeton using regional road and forest service road networks that run near the property. Access into the property is provided by Glen Lake FSR and associated spur roads, with some areas requiring 4x4 vehicles.

Geological setting

The property lies within the Intermontane Belt of the Canadian Cordillera and is split north-south by the Pennask and Osprey Lake batholiths. The Kathleen Mountain showing is hosted in the Pennask batholith area, while the Golden Lode showing is situated within the Osprey Lake intrusive complex and associated with small porphyry dikes.

Mineralization highlights

Golden Lode MINFILE 092HNE186

  • Golden Lode is one of the two key MINFILE showings identified on the Kathleen Mountain Property.
  • The showing is situated within the Osprey Lake intrusive complex and associated with small porphyry dikes.
  • Historical work included trenching, mapping, geochemistry and drilling focused around the Main Trench area.
  • 1995–2000 drilling under the Main Trench returned anomalous to economic gold and copper values over short core lengths.
  • Reported drill results include 2.07 g/t Au, 9.69 g/t Ag and 0.36% Cu over 3.1 m, and 6.1 g/t Au, 23.79 g/t Ag and 0.79% Cu over 1.38 m.

Kathleen Mountain MINFILE 092HNE034

  • The Kathleen Mountain showing is hosted in the Pennask batholith region in the northern part of the property.
  • Early work included mapping, geochemistry and limited geophysics in the 1970s.
  • Exel Explorations completed six diamond drill holes in 1974 and 1975 totaling 170 m.
  • Inco and others completed reconnaissance mapping and prospecting in the 1980s.
  • The area remains relevant to the broader porphyry copper-molybdenum and skarn exploration model.

2018 DCIP and Magnetics

  • SJ Geophysics acquired 34 km of Volterra 3D induced polarization data and 34 km of ground magnetic data.
  • The survey grid consisted of 17 north-south lines, each 2 km long and spaced 200 m apart.
  • The resistivity model outlines a likely contact between the Pennask and Osprey Lake batholiths.
  • A kilometre-wide north-south corridor of low to moderate resistivity features is interpreted as highly fractured.
  • A strong low-resistivity feature less than 500 ohm-m is approximately 200 m wide and extends to depth.

Exploration Targets

  • The 2018 model highlights two subtle chargeability features with associated resistivity and magnetic features.
  • One target is associated with a low-resistivity fault, a magnetic high and subtle near-surface chargeability.
  • A second circular chargeability pod is approximately 200 m in diameter and centered near 709800E / 5513900N.
  • The kilometre-wide corridor warrants further investigation as a possible controlling structure for mineralization.
  • The report recommends integrating geophysics with geology, soil geochemistry, airborne magnetics and radiometrics.

Exploration potential

Kathleen Mountain combines known MINFILE showings, historical trenching and drilling, porphyry-style intrusive geology, and 2018 DCIP and magnetic targets. The north-south resistivity corridor, subtle chargeability features, magnetic features and historic Golden Lode drill results provide a strong basis for further integrated interpretation and target refinement.
