Titan Mining Corporation (NYSE-A:TII) (TSX:TI), a U.S.-focused critical minerals producer and developer, today announced positive results across its full graphite processing chain for the Kilbourne Graphite Project, from ore concentration through to battery-grade spherical graphite. The results confirm the Company’s Preliminary Economic Assessment design assumptions at the concentrator and demonstrate battery-grade purity and above-average yields at the downstream pilot stage, supporting the ongoing Feasibility Study and Titan’s plan to build the first fully integrated U.S. graphite supply chain in over 70 years.

HIGHLIGHTS

• Concentrator flowsheet validated: Locked-cycle testing produced a 95.9% C(t) graphite concentrate at 91.4% recovery, exceeding the PEA design basis of 95% concentrate grade and 90% recovery.
• Preferred commercial purification process confirmed: Metallurgical test work selected for the preferred purification flowsheet for the Feasibility Study, consistently producing battery-grade purified graphite (≥99.90% Fixed Carbon).
• Industry-leading spherical graphite yield: Approximately 66% of concentrate converted into spherical graphite products, exceeding the industry average of approximately 50%.
• Engineering progressing across the value chain: Engineering of both the concentrator and Secondary Transformation Plant continues to advance as part of the Feasibility Study.
• Demonstration plant supporting commercialization: Ongoing production at plant with design capacity of 1,200 mt per annum, is generating representative Kilbourne concentrate for downstream pilot campaigns, customer qualification and commercial-scale engineering.

“These results confirm two things: our concentrator performs as designed in the PEA, and our downstream process turns that concentrate into battery-grade material at yields well above the industry average. Together, they de-risk the Kilbourne Feasibility Study from the mine face through to the finished product. We’re now focused on completing customer qualification and advancing toward construction,” said Rita Adiani, President and Chief Executive Officer of Titan.

As part of the ongoing Feasibility Study, Titan completed a metallurgical optimization program at SGS Lakefield to refine the concentrator design for the Kilbourne Graphite Project. The optimized flowsheet closely aligns with the PEA design, requiring only minor refinements to further improve performance.

Locked-cycle flotation testing produced a 95.9% C(t) graphite concentrate at 91.4% graphite recovery, exceeding the PEA design basis of 95% concentrate grade and 90% recovery. Flake size distribution also closely matched PEA assumptions, providing further confidence in the concentrator design. Variability testing across representative ore types is ongoing to support the final engineering design.

Engineering of the concentrator continues to advance, with vendor testing underway to finalize equipment sizing. In parallel, the Empire State Mine demonstration plant continues producing graphite concentrate to support downstream pilot campaigns and customer qualification activities.

The downstream engineering program continues to advance in parallel with the Kilbourne Feasibility Study.

Metallurgical test work has confirmed the preferred purification flowsheet for the Secondary Transformation Plant, consistently producing ≥99.90% Fixed Carbon purified micronized graphite (PMG). A thermal pretreatment step combined with the selected purification process achieved 99.99% Fixed Carbon for spherical purified graphite (SPG), supporting its suitability for lithium-ion battery applications.

The program also demonstrated an approximate 66% conversion of graphite concentrate into spherical graphite products, significantly above the industry average of approximately 50%, further enhancing the project’s economics.

Representative SPG products have been dispatched for specialist coating and electrochemical testing as part of ongoing customer qualification activities. In parallel, three tonnes of representative Kilbourne graphite concentrate are being prepared for shipment to Dorfner Anzaplan in Germany for the next pilot-scale production campaign. Engineering of the Secondary Transformation Plant and evaluation of its preferred site location continue as part of the Feasibility Study.

The Company also continues to progress the evaluation of the preferred site location for the Secondary Transformation Plant, as outlined in its June 25, 2026 news release.

Qualified Persons

The scientific and technical information contained in this news release (other than in respect of the secondary transformation site) has been reviewed and approved by Oliver Peters, P.Eng., M.Sc., MBA, a Qualified Person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).

The scientific and technical information contained in this news release related to the secondary transformation site has been reviewed and approved by Derick de Wit, FAusIMM, a Qualified Person as defined by NI 43-101.

The Qualified Person has verified the metallurgical data disclosed in this news release, including sampling information, laboratory test procedures, analytical results, calculations, and interpretations underlying the technical information presented. Verification activities included a review of sample selection and compositing procedures, chain-of-custody records, laboratory certificates, test protocols, analytical methodologies, mass balance calculations, and the reported metallurgical results. The Qualified Person also reviewed the consistency of the reported results with the underlying laboratory data and confirmed that the conclusions presented are supported by the testwork completed.

The metallurgical testwork program was conducted under a quality assurance and quality control program designed by SGS Lakefield to ensure the reliability of the results. Test procedures were developed and executed in accordance with industry-standard laboratory practices. Equipment calibration, procedural checks, duplicate analyses, and internal laboratory quality control measures were utilized, where appropriate, throughout the program. Sample preparation, handling, and testing were conducted under controlled laboratory conditions, and all analytical results were reviewed for reasonableness and internal consistency.

The metallurgical samples utilized for testing were selected to be representative of the mineralization and material types under evaluation; however, metallurgical performance can vary throughout a deposit due to changes in mineralogy, grade, weathering, and other geological factors. As with all laboratory-scale testwork, the results reported herein may not be fully representative of future plant-scale performance. Factors that may materially affect the accuracy or reliability of the reported results include sample representativity, variability in feed characteristics, analytical precision, test conditions, scale-up assumptions, and process operating parameters.

The metallurgical testwork was conducted by SGS in Lakefield, Ontario, Canada. The laboratory is independent of the Company. Testing was performed on a Master composite weighing approximately 200 kg. The test program included comminution testing and laboratory flotation testing. Analytical determinations were completed using industry-standard methods appropriate for the material and products under evaluation, including carbon analysis, sulphur analysis, ICP-OES, XRF, and particle size analysis. The Qualified Person considers the analytical and metallurgical procedures used in the program to be appropriate for the objectives of the testwork and the nature of the mineralization being evaluated.
