Thor Marmot

Thor Marmot hosts eight exploration prospects with significant Au, Cu and Mo anomalies. Historical work including geochemistry, geophysics, alteration mapping and Terraspec analysis indicated the potential for porphyry style mineralization. The most advanced exploration target is Thorne, a Cu-Au porphyry prospect with a 1,000 x x 1,000m footprint. Thorne demonstrates an encouraging geophysical anomaly that coincides with Cu-Au-Mo soil and rock anomalies and varying potassic, chloritic and propylitic alteration. 


The Thor Marmot property is located in the Toodoggone District, 20km South of Centerra Gold's Kemess Project, which comprises the permitted Kemess Underground and advanced-stage Kemess East deposits, and the past-producing Kemess South deposit. Other major projects within the area include Benchmark's Lawyers Project and Centerra's Mt. Milligan Mine. Thor Marmot is also close to several exploration stage projects owned by NorthWest Copper, GGL Resources Corp and Wedgemount Resources.

Thor Marmot benefits from excellent infrastructure, with an all weather access road and transmission line running through the property. The local First Nations communities are proactive to exploration and engagement.

The Toodoggone District is a 100 x 30 km belt of calc-alkalic Cu-Au-Mo porphyry, alkalic Cu-Au porphyry and epithermal Au-Ag deposits in north-central British Columbia. The Toodoggone is located within the Sitkine Terrane, part of the Intermontane Belt. 

Volcanic rocks of the Upper Triassic Takla Group volcanics underlie eastern portion of Thor-Marmot property. Takla Group Volcanics include coarse grained plagioclase-augite-phyric basalt or andesite flows and minor amounts of intercalated volcaniclastic rocks, probably of the Savage Mountain Formation. Lower to Upper Cretaceous Sustut Group clastic sedimentary rocks underlie the western part of the property, although exposure is poor and contacts are not well defined.


The Moose Valley Fault is a significant NNW trending structure that dissects the property.

Early Jurassic Black Lake Intrusive Suite intrude Takla Group volcanics across the property. Equigranular granodiorite plutons and smaller porphyritic bodies and dykes of quartz-eye porphyry; quartz-plagioclase-biotite porphyry; and plagioclase porphyry.

The Thorne Showing demonstrates a typical alkalic porphyry alteration pattern:

Chlorite-dominant alteration in volcanics, transition to strong propylitic alteration with patchy potassic alteration at depth. Potassic alteration is locally strong within Black Lake Suite dikes and quartz mineralized veins. Copper surface geochemistry values increases towards potassic alteration


Lithology around the prospect consists of Late Upper Triassic Takla Group basalts, andesites, feldspar porphyry, basalts/andesites and augite porphyry basalts with localised volcanic breccia textures. These are intruded by monzonites, diorites and granodiorites of the Early Jurassic Black Lake Intrusive Suite.

Magnetic high centered around a large Cu-Au-Mo soil geochemical anomaly around the entire prospect. Mineralization associated with the magnetic high is hosted in massive sulphide to quartz veins as massive chalcopyrite-bornite-pyrite-magnetite.

4 km of IP completed in 2022 at the Thorne showing. Chargeability highs at depth correlate with elevation of outcropping potassic alteration and high surface Cu values along ridge to south.  Increasing chargeability at depth could correlate with a potassic altered zone
