Manganese X Energy Corp. Kicks Off Battery Hill Prefeasibility Study, Selecting ABH Engineering Inc. and GEMTEC Consulting Engineering and Scientists Limited

Manganese X Energy Corp. announced on December 3, 2025, that it has officially commenced the Prefeasibility Study (PFS) for its flagship Battery Hill High Purity Manganese (HPMSM) project. The company has selected ABH Engineering Inc. to lead the PFS, with GEMTEC Consulting Engineering and Scientists Ltd. providing expertise for critical environmental, geotechnical, hydrogeological, water management, and community-impact components.

Work on the PFS is slated to begin immediately, with an anticipated completion target in 2026. The study will integrate recent advancements in processing, ore sorting, and metallurgical test work to optimize the project's flowsheet, reduce risk, and enhance long-term shareholder value. CEO Martin Kepman emphasized that the selection of ABH and GEMTEC will ensure the PFS adheres to the highest standards of environmental responsibility, technical rigor, and economic value.

This news represents a positive, albeit routine, step forward for Manganese X Energy Corp. The commencement of the Prefeasibility Study (PFS) for the Battery Hill project is a critical development milestone that the company has been consistently working towards. Previous news releases indicated an intention to initiate the PFS in Q2 2025 (February 5, 2025 news), then Q3 2025 (August 12, 2025 news), with subsequent updates referring to "PFS preparation" (November 6, 2025 news). The actual kick-off in December 2025 is slightly later than the initial Q2 target but consistent with the more recent guidance.

The selection of ABH Engineering Inc. and GEMTEC Consulting Engineering and Scientists Ltd. indicates a commitment to a thorough and professionally managed study. ABH brings mining expertise and economic modeling, while GEMTEC specializes in environmental and community engagement aspects crucial for project de-risking and permitting.

While positive, this announcement is a planned operational update rather than an unexpected breakthrough. The market likely anticipates such progress given the company's stated development path. Therefore, it is unlikely to have a significant material impact on the stock price beyond what is already factored in, serving more as a confirmation of steady execution. A material positive impact would likely stem from actual PFS results demonstrating robust economics or securing substantial financing/offtake agreements.

Manganese X Energy Corp. (TSXV: MN) is a Canadian critical minerals company focused on developing a secure, sustainable, and ethical supply chain for high-purity manganese materials for the electric vehicle (EV) and energy storage system (BESS) markets in North America.

Its flagship project is the Battery Hill High Purity Manganese (HPMSM) Project, located in Woodstock, New Brunswick, Canada. The company wholly owns the claims, which are subject to a 3% Gross Metals Royalty to Globex Mining Enterprises. The project is strategically positioned as one of the largest manganese carbonate deposits in Canada and the United States.

Key developments and goals: - Prefeasibility Study (PFS): Currently underway, targeting completion in 2026, aimed at optimizing the flowsheet and de-risking the project. - Ore Sorting: Phase 2 results showed an 80% mill feed upgrade improvement, projected to reduce CAPEX and OPEX, and improve project economics. The ore is highly amenable to sorting. - Metallurgical Process: Development of a proprietary, patent-pending process for producing high-purity, battery-grade manganese. - Battery Testing: Advanced to Phase 3 testing with U.S. battery innovator Charge CCCV (C4V) after exceptional Phase 2 results (70% capacity retention after 4,600 cycles, outperforming conventional NMC and LFP/LMFP batteries). - Resource Definition: Completed a drill program to upgrade inferred resources to Measured and Indicated categories, with a new NI 43-101 compliant resource estimate underway. - Strategic Importance: Aims to be the first publicly traded manganese mining company in Canada and the US to commercialize EV-compliant HPMSM, supporting North American supply chain independence. - Environmental Focus: Emphasizes carbon-friendly methodologies, reduced energy/water consumption, and decreased tailings storage requirements.

The company also holds a 40% interest in the Peter Lake Copper-Nickel-Cobalt Property, subject to a 2% Net Smelter Royalty (NSR) with an option to buy back 1% for $1,000,000. It also has a "lease to own" agreement for 73 hectares in the Battery Hill deposit area (Iron Ore Hill Road Property).
