We are a U.S.-domiciled critical minerals and advanced materials company focused on establishing a secure, resilient domestic U.S. manganese supply chain. Our principal asset is the Emily manganese deposit in Minnesota, the highest-grade manganese deposit in North America.

North Star Manganese Project

Our flagship project is the North Star Manganese Project, a 100% U.S. domestic initiative comprising two core components:

• Mining operation: The Emily manganese deposit in Minnesota
• Processing facility: A planned Gulf Coast facility designed to produce high-purity manganese sulfate monohydrate (HPMSM) and electrolytic manganese metal (EMM)

The project has been the subject of extensive technical work, including a Preliminary Economic Assessment prepared in accordance with National Instrument 43-101 Standards of Disclosure for Mineral Projects.

Strategic Focus

Our mission is to strengthen America's critical mineral independence by developing a secure domestic supply of high-purity manganese chemical and metal products for North American electric vehicle and energy storage batteries, defense applications, critical infrastructure, specialty alloys, advanced technologies, and industrial uses. With manganese playing an increasingly important role in lithium-ion battery formulations and with no current domestic U.S. production of manganese ore, HPMSM, or EMM, the North Star Manganese Project represents a strategic opportunity to reduce dependence on foreign supply chains and support U.S. industrial, energy, and national security priorities.

Recent Technical Work

In June 2026, we completed a positive ore sorting assessment on drill core from the Emily Manganese Deposit. The results showed that particle-scale ore sorting upgraded a drill core dataset averaging approximately 8.2% Mn to approximately 17.5% Mn while recovering approximately 92% of the contained manganese, with the potential to reject 57% of material prior to downstream processing. This work demonstrates that ore sorting could be a significant value-enhancing technology for the project, potentially turning sub-cut-off mineralization into economic ore and reducing downstream processing costs.

Non-Core Assets

We also hold non-core Nevada silver assets, the Corcoran and Belmont silver-gold properties in Nye County, Nevada. In January 2026, we entered into a definitive purchase and sale agreement to sell these assets, though that agreement terminated in October 2026 following the buyer's failure to make a scheduled payment. We are currently in discussions with other prospective purchasers for these assets.

Here's a rundown of our current leadership team, drawn from our September 2026 Information Circular and our Leadership page.
