Silverboss surrounds Glencore Canada’s past-producing, open-pit and underground, high-grade
A total of 406 soil, 2 silt and 27 rock and core samples were collected at Silverboss in 2021. The Gus copper anomaly, with values ranging from 104 ppm (90thpercentile) to 407 ppm Cu has doubled in size to greater than 4.5 square kilometres and remains open in several directions (Figure 2). Gus occurs within a very strong regional magnetic high, which is associated with the
Palladium, silver and nickelsoil anomalies are coincident with copper and also remain open at the northeast end of the Gus copper target, following the contact of the gabbro-diorite with mafic volcanic rocks of the
Sampling of Historic Drill Core
In 1971,
In 2021, seven randomly selected samples2from the top-most boxes of the 1971 drill core returnedweakly anomalous copper (68 to 651 ppm) and palladium (9 to 39 ppm)(Table 1). The core is very poorly preserved however some depth marker blocks could still be discerned. The samples were collected between blocks over intervals from 1.8 to 3.0 m in length. Values for other PGM metals (Pt, Pd, Rh, Ir, Os, Ru) are near or below detection limit in 5 samples analyzed for the full PGE suite.

Mineralization observed in the 1971 core consists of finely disseminated chalcopyrite and pyrite hosted in fresh to altered, medium to coarse-grained gabbro-diorite. Alteration includes chlorite, amphibole, epidote, sericite, carbonate and hematite.
Style and Geological Setting of Gus Mineralization
The setting in gabbro-diorite of the Late Triassic to Early Jurassic Takomkane batholith, combined with the mineralogy and alteration suggest that the Gus target has characteristics of both porphyry Cu-Au and magmatic Cu-PGE styles of mineralization.
The most significant porphyry Cu-Au deposits in the Takomkane batholith are the Woodjam deposits, located 32 km northwest of Silverboss. At least six zones of porphyry mineralization have been identified at Woodjam. These are hosted in both alkaline to sub-alkaline monzodiorite and calc-alkaline quartz monzonite phases of the Takomkane batholith, which intrude into
The Gus mineralization also has some characteristics of gabbro-hosted magmatic Cu-PGE deposits in BC and elsewhere. The association of Cu, Pd, Ag and Ni in soils, the relatively high Pd to Cu ratio and low sulphide content in drill core, and the fresh to weakly altered gabbroic host rocks are reminiscent of certain low-sulphide magmatic Cu-PGE deposits including the feasibility-stage Marathon project in
Magmatic Cu-Ni-Co-PGE mineralization is know to be present in several places in
Additional work is needed to better understand the genesis and controls of the Gus mineralization, and to prospect the new soil anomalies to find better Cu – PGE values in rock. Geological studies including polished thin-section and whole-rock geochemistry are underway. Additional core sampling will be attempted in 2022.
Claim Acquisition and Other Copper Targets
To cover potential extensions of the Gus copper target, four claims, totaling 2503 hectares, were acquired by staking. The Company now controls the full 18 km of strike length of the prospective geology and magnetic anomaly that hosts the Gus copper target.
Review of historic literature identified two copper prospects in geological settings similar to Gus that are now covered by Happy Creek mineral tenures (Figures 1 and 2). The Telephone Hill (
Silverboss Shaft and Dogtooth Gold-Silver Targets
In summer 2021 the Company completed a field review and collected 14 rock samples from the Silverboss Shaft, Dogtooth and
At the Silverboss Shaft, four 2021 grab samples of dump material returned assays ranging from0.216 to 9.28 g/t Au, 2.44 to 299 g/t Ag and .055 to 3.12% Cu.2Previous work by Happy Creek and others outlined a 0.5- to 2.0-metre-wide shear-vein that was traced for 350 metres along a northeast trend, as evidenced by several pits and trenches and a single short adit and shaft. It is accessible by an old dozer/all-terrain vehicle trail from the nearby Boss mine access road. The mineralized zone is hosted by diorite of the Takomkane batholith and feldspar phyric dikes, and is reported to have been discovered before 1917. Sampling prior to 2021 by Happy Creek and previous operators has returned values ranging from0.22 to 72.8 g/t Au, 28 to 1,026 g/t Ag, and trace to 11.95 % Cufrom grabs of dump materials and chip samples up to 0.5 metre in width.1,2Despite the good access, locally high grades, and nearby Induced polarization (IP) chargeability features extending from surface to over 350 metres in depth, there is no record of any previous drilling near the shaft.
At the Dogtooth vein target 900 m to the south, three 2021 samples returned1.86 to 2.96 g/t Au, 3.89 to 257 g/t Ag, and 78 ppm to 6.00% Cu2, plus highly anomalous arsenic, bismuth, antimony and tellurium values from quartz-sulphide veins cutting diorite. Work by Happy Creek in 2005-2006 returned assay values of0.05 to 53.18 g/t Au and 0.8 to 365 g/t Ag in grab samples, and a one-metre chip assayed 10.06 g/t Au and 26 g/t Ag.1, 2Also present nearby are zones of sheeted and stockwork veinlets of quartz with narrow selvages of epidote, chlorite and potassium feldspar alteration. The prospect occurs within a broad gold-in-soil anomaly. The geological setting and metal association at Dogtooth are suggestive of intrusion-related gold deposits similar to Kinross’ Fort Knox mine in
