The report, prepared by WSP Canada Inc., projects a post-tax net present value of USD$183 million for the project over a 20-year mine life. By utilizing the mine's historical infrastructure and existing industrial footprint, the company aims to minimize capital intensity, with initial expenditures estimated at CAD$65.9 million. The operation is designed to produce high-grade graphite concentrate, targeting approximately 95% graphitic carbon content to feed North American industrial and battery supply chains.

Global Battery Materials eyes Ontario mine restart with 67% IRR
Global Battery Materials Corp. has unveiled a positive preliminary economic assessment for the Kearney Graphite Project in northeastern Ontario, signaling a potential return to production for the dormant site. The company anticipates a 1.3-year payback period and a 67% internal rate of return on the brownfield redevelopment.

Management is positioning the Kearney restart as a key component of its strategy to secure critical mineral supply chains outside of China. CEO Eric Miller noted that the project's proven history and brownfield status offer a faster path to domestic production than greenfield alternatives. The company plans to transition the site from initial diesel power to a regional 44 kV grid connection to drive down operating costs from CAD$31.35 to CAD$25.50 per tonne milled. While the assessment is promising, the company acknowledged risks including historical data reliance and pending regulatory permit renewals, with a definitive feasibility study set to follow.
