XXIX Metal Publishes Opemiska's Preliminary Economic Assessment Technical Report

On December 3, 2025, XXIX Metal Corp. announced it has filed the independent Preliminary Economic Assessment (PEA) technical report for its 100%-owned Opemiska Copper Project in Quebec. The filing on SEDAR+ and the company's website formalizes the results that were initially announced on October 21, 2025. The report confirms the previously disclosed robust project economics, including a base case after-tax Net Present Value (NPV) at an 8% discount rate of C$505 million, an Internal Rate of Return (IRR) of 27.2%, and an initial capital expenditure of C$617 million.

The filing of the NI 43-101 technical report is a procedural and regulatory requirement following the announcement of the PEA results in October. It does not introduce any new material information to the market. The key economic highlights, which are the primary drivers of valuation, were fully disclosed on October 21, 2025. The stock price reacted positively at that time, moving from the C$0.10 range to the C$0.12-C$0.14 range where it has since consolidated.

Therefore, this news is a routine, neutral event. It adds a layer of technical validation and credibility by having the report signed off by independent Qualified Persons, but it does not change the investment thesis or the project's perceived economics. The market has already priced in the positive PEA results. This filing meets expectations and confirms the company is proceeding as planned, but it is not a catalyst for a re-rating of the stock. The focus now shifts to the next steps in derisking the project.

Looking at the company's progression over the past year, it has systematically met its stated milestones: - Jan-May 2025: Successfully drilled the Saddle Zone, identifying new potential. - June 2025: Delivered an updated and larger Mineral Resource Estimate (MRE) as promised. - Aug 2025: Secured C$6 million in financing to fund the next exploration phase. - Oct 2025: Delivered a positive PEA for Opemiska. - Nov 2025: Commenced and provided a positive visual update on the Cooke Gold Zone drill program. - Dec 2025: Filed the technical report for the PEA.

This demonstrates competent execution. However, the PEA's release has shifted the primary risk from exploration to development. The C$617 million initial capital requirement is a staggering hurdle for a company with a market capitalization under C$50 million.

XXIX Metal Corp. is a Canadian copper exploration and development company. Its portfolio is centered on two large, past-producing copper projects in Eastern Canada. - Flagship Project (Opemiska): Located in the Chapais-Chibougamau district of Quebec, Opemiska is a brownfield project that includes four former copper-gold mines. The company is advancing it as a large-scale, open-pit operation. The December 2025 PEA outlines a 17-year mine life with an after-tax NPV8% of C$505 million and an IRR of 27.2%. - Secondary Project (Thierry): Located in Pickle Lake, Ontario, this is another past-producing copper-nickel project with a significant existing resource. The company is currently re-validating historical data with plans for a maiden drill program in early 2026.
