Monument Entered Into a Collaboration Agreement, Gives GBR Access to Burnakura Mill

VANCOUVER, British Columbia, April 02, 2025 (GLOBE NEWSWIRE) -- Monument Mining Limited (TSX-V: MMY and FSE: D7Q1) (“Monument” or the “Company”) today is pleased to announce that it has signed a Memorandum of Understanding (“Collaboration Agreement”, or “MOU”) with Great Boulder Resources (“Great Boulder”, ASX: “GBR”) for collaboration to potentially process ore from Great Boulder’s Side Well Gold Project through Monument’s Burnakura Mill at Meekatharra, Western Australia subject to availability.

President and CEO Cathy Zhai commented, "I am very pleased with thanks to Mr. Andrew Paterson, the Managing Director of Great Boulder, for considering Burnakura mill as their treatment option and for his willingness to collaboratively explore the best solution beneficiary to both parties in optimization of potential production. It will give an opportunity for exploration companies to generate cash flow as gold prices surge to historical record highs. While junior companies continue to face their own challenges and navigate the inherent risks of the natural resource industry, we are working hand in hand to find a win-win solution in the region.”

Background

Following the successful commercial production of the upgraded sulphide gold concentrate plant at Selinsing Gold Mine, Monument is now advancing its Murchison Gold Project towards potential commercial production. SRK Consulting (Australasia) Pty Ltd (“SRK”) is currently engaged to provide economic assessments, including evaluating the Burnakura mill capacity for initial re-start and potential upgrade options up to 750K tpa. With a proven track record for building-up and advancing operational mines, Monument continues to leverage its strong production management team to drive growth and efficiency.

Monument has an estimated Mineral Resource of 5.59Mt @ 2.12g/t for 381koz, comprised of Indicated at 4.04Mt @ 2.3g/t gold for 293k ounces, Inferred Mineral Resource of 1.55Mt @ 1.8g/t gold for 88k ounces at Burnakura (“NI 43-101 Technical Report: Updated Mineral Resources, Burnakura Gold Project, Western Australia, Australia”, prepared by SRK, available at www.monumentmining.com); and historical Mineral Resources (JORC Resource) 2.2Mt @ 2.2g/t Au for 153,000oz at Gabanintha, plus 20% free carried interest in the Tuckanarra Gold Project.

Great Boulder is a mineral exploration company with a portfolio of highly prospective gold and base metals assets in Western Australia ranging from Greenfields through to advanced exploration. The Company’s core focus is the Side Well Gold Project at Meekatharra in the Murchison gold field approximately 48 km north of Burnakura (Figure 1), where exploration has defined a Mineral Resource of 7.45Mt @ 2.8g/t Au for 668,000oz Au (340koz @ 3.4g/t Au Indicated, 327koz @ 2.4g/t Au Inferred). The Company is also progressing early-stage exploration at Wellington Base Metal Project located in an emerging MVT province.

Collaboration

The MOU between Great Boulder Resources and Monument Mining is a non-binding agreement setting a framework for the two companies to evaluate the sustainability of the Burnakura plant to treat GBR’s Side Well ore, assess the technical, commercial and logistical requirements for joint operations or toll treatment where applicable, and negotiate commercial terms for ore treatment at Burnakura.

With both parties undertaking scoping studies on their respective operations, the MOU allows GBR and Monument to collaboratively share scoping study outputs enabling optimization of mining and ore processing. The MOU also allows collaboration on each company’s area of technical expertise, including GBR’s knowledge of local geology and gold mineralization, exploration and local stakeholder relationships combined with Monument’s expertise in processing, mining and metallurgy.

In the event Monument wishes to use Burnakura’s milling capacity to toll treat third-party ore sources, the Agreement provides pre-emptive processing rights for GBR subject to availability. During the course of the Agreement each company will remain responsible for its own study costs.

The parties will negotiate a definitive agreement when it is appropriate.
