Detailed work has identified numerous Areas of Interest (AOIs) of which 19 have been classified as high-priority targets. These targets have been ranked and will be assessed in future exploration programs with focused field programs.
Kechika Trough Targeting Initiative
In mid-2020 the Company initiated a district wide, evaluation of its
This work has utilized the extensive Kechika Trough Exploration Database to help identify underexplored regions of its properties by identification of new AOIs and near-term drill targets. The data base represents a comprehensive effort to compile and integrate over 40 years of exploration data derived from B.C. Assessment Reports, B.C. Property Files, internal reports and modern exploration that the Company has itself undertaken, including high-resolution, airborne geophysical surveys and targeted geochemical and mapping campaigns.
Targets
The Company has identified 19 high-priority targets from a pool of 95 AOIs across all its Kechika Trough tenure including key properties such as Akie, Pie, Mt. Alcock, and Bear/Spa. A set of district specific exploration criteria have been established from the study of past discoveries in the region (e.g.,
The 19 ranked high-priority targets are located on almost every property within the district. Several target areas are classified as drill-ready while others require additional work in order to be upgraded. In some cases, these high-priority targets are associated with adjacent or proximal AOIs that pending exploration success could elevate their ranking.
One of the highest priority targets is the Mt. Alcock prospect located approximately 40 kilometres northwest of the Akie property and 20 kilometres northwest of
Limited and extremely shallow drilling by previous operators intersected mineralisation with significant grade such as 9.30% combined Zn+Pb and 1.20 oz/t Ag over 8.8 metres in drill hole AK-89-3 including 14.20% combined Zn+Pb and 1.60 oz/t Ag over 3.6 metres () hosted in Gunsteel formation shale. Facies models recently derived by the Company from close examination of the
Other high-priority targets are present on the Saint and Thro properties located to the northwest of the Driftpile deposit. Targets on the Saint property are associated with a long continuous Pb soil anomaly with approximate dimensions of 3,500m x 500m with values consistently in excess of 100 ppm and localized areas where values can range up to 6,500 ppm. Historical operators recommended drilling for this target area but it was never pursued. On the Thro property historical work outlined an approximate 600m x 600m Pb soil anomaly with values consistently in excess of 100 ppm and range up to 12,500 ppm. Rock chip samples in the vicinity were also elevated in lead and rock chips taken from a hand dug trench in 1978 returned highly anomalous Pb values in excess of 400 ppm and ranging up to 5,600 ppm. These anomalies represent some of the largest in the district and both remain untested by drilling. Almost all the known deposits in the district are associated with a distinct Pb soil signature making the targets on the Saint and Thro properties attractive drill targets.
Work will continue to refine these high-priority targets and AOIs as well as identify new target areas as additional datasets are incorporated into the database.
Kechika Trough Exploration Database
The Kechika Trough Exploration Database represents a comprehensive effort to compile and integrate over 40 years of exploration data derived from B.C. Assessment Reports, B.C. Property Files, internal reports and documents, and more. Data was captured at property to regional scales and includes drilling, geological, geochemical, geophysical as well as satellite and geographical datasets. Currently, the database exceeds 155 GB in size and includes over 1,250 rock samples,1,775 silt samples, 24,000 soil samples, and 13,875 meters of drilling. Collectively this work represents in excess of
The ability to access, display, layer, and analyze multiple datasets at both the property and regional scales, using modern GIS software such as ArcMap and QGIS, is a tremendous tool to increase the chances of exploration success that was unavailable to historical workers. Work will continue to synthesize and incorporate any new historical data into the database that can be utilised to aid in the definition of new exploration targets.
The 100% owned Akie property is situated within the Kechika Trough, the southernmost area of the regionally extensive

The Company announced robust positive results from the 2018 Preliminary Economic Assessment (PEA). The PEA envisages a conventional underground mine and concentrator operation with an average production rate of 4,000 tonnes per day. The mine will have an 18-year life with potential to extend the life-of-mine (LOM) through resource expansion at depth.
