• These advancements position the company to evaluate commercial options for the project, including partnerships, a spin-out, or advancement towards an economic study.

Sentiment

Score: 7

Explanation: StockSavvy.ai views this as a positive development, with significant improvements in metallurgical recoveries and concentrate grades, and the potential to unlock additional value from by-product metals. The clear pathway towards an updated MRE and evaluation of commercial options supports a cautiously optimistic outlook.

Positives

• Confirmed ability to produce separate high-grade copper and nickel concentrates, a viable alternative to historical bulk concentrate production.
• Copper concentrate achieved 81.3% recovery at a high 30.2% Cu grade with minimal Ni content (0.62%).
• Nickel concentrate grade increased to 10.9% Ni with 54.4% recovery.
• Copper recovery increased by 16% compared to the 2024 MRE inputs (from 70.0% to 81.3%).
• Copper losses to tailings were cut by 56% (from 26.2% to 11.4%).
• Nickel concentrate grade jumped 60% compared to the 2024 MRE inputs (from 6.8% to 10.9%).
• Potential for meaningful incremental upside from PGEs, gold, silver, and cobalt, which were not comprehensively assayed historically.
• Advancements support the upcoming Updated MRE, expected in Q2 2026.

Negatives

• While recoveries and grades have improved, the overall nickel recovery to the nickel concentrate is 54.5%, with 41.3% of Platinum and 18.0% of Palladium also recovered in this stream.
• The total expected payable recovery across both concentrates is 88.5% for copper and 54.4% for nickel, with significant losses to tailings for other metals like Platinum (43.8%) and Palladium (34.2%).
• The company acknowledges that inferred mineral resources have a greater amount of uncertainty and may not be economically or legally mineable.

Risks

• There is no assurance that any mineral resources reported under NI 43-101 will be the same as reserve or resource estimates prepared under S-K 1300.
• Investors are cautioned not to assume that any part or all of indicated or inferred mineral resources will ever be converted into a higher category or into mineral reserves.
• Inferred resources have a greater amount of uncertainty as to their existence and whether they can be mined legally or economically.
• Capital and operating costs may vary significantly from estimates.
• Preliminary nature of drilling and metallurgical test results.
• Payabilities of metals may vary from expectations.
• The ability of exploration results to predict mineralization.
• Delays in obtaining or failures to obtain required governmental, environmental or other project approvals.

Future Outlook

The company expects to complete an updated Mineral Resource Estimate (MRE) for the Selkirk Project in Q2 2026, incorporating the recent metallurgical results. Following the MRE completion, NexMetals anticipates being positioned to evaluate various commercial options for the project, which may include potential partnerships, a spin-out, or advancing towards an economic study. Further optimization and variability testing are planned to refine process parameters and support evaluation of a potential project restart.

Management Comments

• "Selkirk is an advanced, past-producing asset that we believe remains underappreciated, and hence undervalued, in todays market."
• "These metallurgical results announced today mark a major step toward unlocking that value."
• "We are seeing strong step-changes across key metrics compared to the 2024 MRE: copper recovery has increased to over 81%, nickel concentrate grade has increased to 10.9%, and total palladium recovery has increased to 78% from 59%."
• "At the same time, copper losses to tailings have been cut by more than half, highlighting the efficiency of the process."
• "Beyond the core metals, this work is also uncovering additional value from metals that were not comprehensively assayed in historical datasets, including PGEs, cobalt and silver which have the potential to provide meaningful incremental upside to overall project economics."
• "Combined with strong resource continuity and expansion potential, we believe Selkirk is increasingly emerging as a compelling development opportunity, all in the context of rising commodity prices."
• "Upon completion of the New MRE, the Company expects to be positioned to evaluate a range of commercial options for Selkirk, which could include options such as potential partnerships, a spin-out, or advancement toward an economic study, building on ongoing value creation and defining a clear pathway to realizing full value for shareholders."

Industry Context

StockSavvy.ai notes that NexMetals' announcement aligns with a broader industry trend of re-evaluating and optimizing processing methods for historical mining assets, particularly those with complex polymetallic orebodies. The focus on producing separate, higher-grade concentrates rather than bulk concentrates is a strategic shift driven by evolving smelter economics and the increasing value of by-product metals like PGEs, silver, and cobalt.

Stakeholder Impact

• Shareholders: Potential for increased project value and future economic studies, partnerships, or a spin-out, leading to potential realization of value.
• Creditors: Improved project economics could strengthen the company's financial standing and ability to service debt.
• Employees: Advancements in project development could lead to future employment opportunities.
• Suppliers: Increased activity and potential development could lead to demand for mining equipment and services.

Next Steps

• Complete additional flowsheet development testwork to further improve recoveries and concentrate quality.
• Integrate metallurgical and re-assay results into the New MRE.
• Obtain full concentrate specifications to confirm product quality and assess the presence of any deleterious elements.
• Conduct mineralogical investigations on nickel cleaner 1 and rougher tailings to better define nickel deportment and liberation characteristics.
• Plan further optimization and variability testing to refine process parameters, inform mine sequencing, and support evaluation of a potential project restart.
• Evaluate a range of commercial options for Selkirk upon completion of the New MRE.

Key Dates

Recommendation

The metallurgical results are highly encouraging, demonstrating significant improvements in processing efficiency and the potential to unlock substantial additional value from by-product metals. This strengthens the development case for the Selkirk project. However, the company is still in the process of updating its MRE and evaluating commercial options. While positive, these are not yet definitive production or economic study outcomes. Therefore, a 'hold' recommendation is appropriate, pending further de-risking through the completion of the MRE and the clarity on future commercial strategies.
