U.S. Patent Office Grants Manganese X Battery Grade High-Purity Processing Patent

• Most Recent Event: On April 15, 2026, Manganese X Energy Corp. received a U.S. patent grant from the U.S. Patent Office for its proprietary purification process of manganese sulphate.
• Technology Scope: The patent covers high-purity processing critical for producing battery-grade manganese used in lithium-ion batteries (EVs and energy storage).
• IP Portfolio Context: This follows a South African patent acceptance on February 10, 2026. Parallel applications are pending in Canada, Mexico, and Australia.
• Project Integration: The technology supports the Battery Hill project prefeasibility study (PFS) in New Brunswick, Canada.
• Historical Progression:
  • September 2025: Phase 2 battery testing showed 70% capacity retention after 4,600 cycles with partner C4V.
  • December 2025: PFS officially kicked off with ABH Engineering and GEMTEC Consulting.
  • February/March 2026: Geotechnical drilling initiated (3 holes, ~550m) and metallurgical optimization continued with Kemetco Research.
• Management Commentary: CEO Martin Kepman stated the patent reinforces the company's commitment to building a secure domestic supply chain and validates their technology strength.

• Rating Justification: The news is categorized as Routine - Positive because the U.S. patent application was previously disclosed in February 2026 (pending status). The grant confirms expectations rather than introducing new, unexpected market-moving data.
• Strategic Value: While routine, securing IP in the United States is critical for a North American supply chain narrative, which often commands valuation premiums in the critical minerals sector.
• Comparison to Historical Data: This milestone follows significant operational progress (battery testing and PFS initiation) that occurred earlier in 2025/2026. The patent protects the processing technology required to monetize the resource defined in those earlier tests.
• Market Expectation: Given the prior announcement of pending applications, this release is incremental validation rather than a fundamental shift in project economics or viability.

• Company: Manganese X Energy Corp.
• Flagship Project: Battery Hill High Purity Manganese (HPMSM) Project.
• Location: Near Woodstock, New Brunswick, Canada (15 km from U.S. border).
• Asset Type: One of North America's largest manganese carbonate deposits.
• Strategic Goal: Vertically integrated North American supplier of battery-grade manganese for EV and energy storage markets.
• Current Stage: Prefeasibility Study (PFS) advancement with geotechnical drilling and metallurgical optimization underway.
