Effective grade
Reconcile representative material against the resource model and quantify the effects of selectivity and material handling.
Thor Project · Bulk Sample Program
Testing commercial-scale recovery before a production decision.
A planned 10,000-tonne program designed to convert geological understanding into mining, metallurgical and engineering data for future economic studies.
The program is intended to generate decision-grade inputs; it is not a production decision or a guarantee of future economic results.

01 · Program purpose
The bridge between resource definition and economic evaluation.
Thor is a complex polymetallic system. The bulk sample is designed to test how representative material behaves at a larger scale—how it breaks, upgrades, separates and converts into marketable concentrate streams.
- 01 Bedrock resource 1.14 Mt indicated resource
- 02 Bulk sample 10,000-tonne permitted program
- 03 Economic studies Potential PEA / PFS inputs
- 04 Future decision Subject to technical, economic and regulatory outcomes
Rock-property calibration
Generate larger-scale physical and mechanical inputs for crushing, handling, water management and facility design.
Smelter readiness
Produce representative concentrate for quality, payable-metal and potential penalty-element evaluation.
Risk reduction
Replace selected assumptions with measured program data before advancing to more capital-intensive studies.
02 · Engineering & flowsheet
A modular route from representative material to concentrate.
Novus Engineering and Gekko Systems developed the pre-concentration concept around a compact, staged circuit. Each stage is intended to produce measurable operating and metallurgical inputs.
- 01Representative feed
True Fissure and Broadview material prepared for the program.
- 02Crush & screen
Controlled size reduction creates consistent feed for separation.
- 03Gravity separation
A Gekko inline pressure jig separates higher-density mineralized material.
- 04Pre-concentrate
Mass reduction is measured before concentrate is moved off site.
- 05Off-site flotation
Locked-cycle work evaluates lead, zinc, silver and gold recovery pathways.
Compact site architecture
Plant, water and coarse-rejects systems designed as one site.
The engineering concept co-locates the process plant, stockpile, water storage, administration and coarse-rejects storage around existing access. The image is conceptual and remains subject to detailed engineering and approvals.

03 · Metallurgical goals
Test the recoveries—and the concentrate quality behind them.
The values below are program targets or reported test-work indications supplied in the project brief. They are not forecasts of commercial production performance.
Reported recovery goalsPercent
Targets and test-work indications require confirmation through the bulk sample and subsequent technical studies.
Gold deportment
Determine where gold reports through the circuit and evaluate appropriate recovery options, including cyanide-related test work where applicable.
Locked-cycle flotation
Evaluate repeatable concentrate performance, circulating loads and the separation of lead- and zinc-bearing products.
Critical-metals audit
Track antimony, indium, cadmium and gallium to understand recovery pathways, payability and potential penalties.
04 · Geotechnical & ESG
Engineering the site around water, terrain and responsible execution.
The program is more than a metallurgy exercise. Site investigation, water management, coarse-rejects storage and engagement all shape whether the concept can advance responsibly.
Knight Piésold program
Company materials describe 12 auger holes, two core holes and bedrock mapping at the True Fissure facilities area.
Coarse rejects storage
The CRSF concept integrates containment, runoff collection and water-treatment interfaces into the site plan.
Water & terrain studies
Planned work includes water-balance refinement and terrain-stability evaluation, subject to program scheduling and approvals.
Information sharing
Company materials state that site-investigation information has been shared with the Ktunaxa Nation as part of the project’s engagement process.
05 · Regulatory clarity
A clearer framework for eligible exploration expenditures.
On January 25, 2024, Taranis reported that the CRA Appeals Division reversed an earlier position and accepted certain 2017–2018 Thor bulk-sample permitting expenditures as Canadian Exploration Expenses.
