Homerun Resources Inc. Rare Earth ElementSeparation Technology Partnership

Homerun Resources Inc. (TSXV: HMR,OTC:HMRFF) (OTCQB: HMRFF) (‘Homerun’ or the ‘Company’) is pleased to announce that it has executed a binding Memorandum of Understanding (‘MoU’) with Magnum Mining & Exploration Limited (‘Magnum’) (ASX: MGU) (OTCQB: MGUFF), to jointly evaluate the application of Homerun’s ultra-pure silica sand for the adsorption and chromatographic separation of rare earth elements (‘REE’) samples supplied by Magnum.

Magnum’s Chairman, Michael Davy, commented: ‘We are very pleased to be initiating this research collaboration partnership with Homerun. We believe this MoU adds smart optionality to our strategy to drive value across our REE portfolio. At minimal cost, we can test whether Homerun’s high-purity silica has the potential to streamline REE separation from our Brazilian ore with a reduced solvent footprint. If successful, Magnum could unlock faster and cleaner routes to supplying REEs to market from its highly prospective Brazilian REE assets, where we have achieved exceptional exploration and leach results to date. We look forward to working with Homerun and by extension contributing to the broader wave of innovation we are seeing in the REE space, both in Australia and internationally.’

Homerun’s CEO, Brian Leeners, commented: ‘This collaboration is an exciting opportunity for Homerun to advance the application of our ultra-pure silica product in a new generation of rare-earth element separation technologies. By leveraging our high-purity feedstock with Magnum’s promising Brazilian rare-earth assets, we believe we can deliver environmentally improved, lower-carbon-footprint processing solutions that are critical to the energy transition. We look forward to driving innovation, lowering costs, and creating value for the stakeholders of both companies through this partnership.’

DETAILS OF THE MOU

Under the MoU the Parties will joint evaluate, the following:

• The bench scale application of the HMR ultra-pure silica sand for adsorption and chromatographic separation of rare earth elements from MGU’s REE projects in Brazil.

• Subject to the success of the bench scale test, a pilot test of the jointly developed solution.

• Eventual commercialisation of the jointly developed solution.

All IP created during the testing phases will be jointly controlled by the Parties. If a Party determines that chromatographic separation of rare earth elements is not suitable to their materials supplied for the purpose of the testing, they may exit the MoU and the other Party will have the right to utilise the IP obtained to their benefit. The Parties shall develop budgets to jointly cover the costs incurred related to the testing phases. The MoU term will expire in 12 months (subject to renewal). The MOU may be terminated on 30 days notice’ or due to an Event of Default or Force Majeure.

BACKGROUND INFORMATION ON HREE SEPARATION TECHNOLOGY

Recent peer-reviewed studies^1,2 report bench-scale continuous extraction chromatography on silica-based media, achieving ≥99.9% purity for individual HREEs using mineral-acid eluents, indicating potential process and environmental advantages versus conventional bulk solvent extraction (while SX remains the current industrial standard). Magnum considers the research opportunity with Homerun an exciting and low-cost initiative that has the potential to accelerate the commercialisation of its Brazilian REE projects.
