GIYANI ANNOUNCES FILING OF DEFINITIVE FEASIBILITY STUDY

Giyani Metals Corp. has filed the National Instrument 43-101 technical report supporting the definitive feasibility study (DFS) for its 100-per-cent-owned K.Hill battery-grade manganese project, located in the Kanye basin in Botswana.

Filing of the DFS for K.Hill

Following the initial announcement of the DFS on May 28, 2026, which showed strong economic returns with an after-tax net present value (NPV), at an 8-per-cent discount rate, of $482-million (U.S.) and an after-tax internal rate of return (IRR) of 20.3 per cent, the full DFS technical report, prepared in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects, has been filed under the company's profile on SEDAR+ and is available for download on the company's newly resigned website.

The results of the DFS disclosed in this news release are unchanged from those announced by the company on May 28, 2026, and readers should review the full DFS for a complete description of the assumptions, qualifications, methodologies and risk factors underlying the DFS.

All financial figures are stated in real U.S. dollars (constant Jan. 1, 2026, money). NPV is discounted at 8 per cent real to the project start date of April 1, 2027.

Nigel Robinson, interim executive chair of the company, commented: "The successful completion and filing of the DFS marks the completion of an important phase of project evaluation and positions the company to advance to the next stages of project development. As demand for battery materials continues to grow, driven by the global shift toward electrification and renewable energy, management believes that manganese may become increasingly important as next-generation battery chemistries continue to develop. We believe K.Hill is well positioned to contribute meaningfully to this evolving supply chain.

"The DFS confirmed the strong economic potential of the project, delivering a posttax NPV of $482-million (U.S.) and an IRR of 20.3 per cent. These results reinforce our confidence in K.Hill's ability to support the growing global demand for battery-grade manganese. The Giyani team has identified potential opportunities to further optimize the project which, if realized, may further enhance project economics.

"We were also pleased to launch our new corporate website, providing stakeholders with improved access to information about our business, projects and strategic progress.

"As we move forward, our focus remains on advancing K.Hill towards development while maintaining our commitment to responsible development practices and continuing engagement with local communities."
