Monument Entered Into a Collaboration Agreement Gives Odyssey Access to Burnakura Mill

VANCOUVER, British Columbia, April 14, 2025 (GLOBE NEWSWIRE) -- Monument Mining Limited (TSX-V: MMY, FSE: D7Q1) (“Monument” or the “Company”) is pleased to announce the signing of a Memorandum of Understanding (“MOU” or “Collaboration Agreement”) with Odyssey Gold Limited (ASX: ODY) (“Odyssey”), through their respective subsidiaries. The agreement outlines a collaboration opportunity to process ore from the Tuckanarra Gold Project (“Tuckanarra”) through Monument’s Burnakura Mill, located near Meekatharra, Western Australia, subject to availability.

Under the existing joint venture arrangement, Monument holds a 20% free carrying interest in Tuckanarra, with Odyssey owning the remaining 80%. The Tuckanarra project is situated approximately 40 km southwest of Monument’s Burnakura gold processing plant in the Murchison Goldfield (Figure 1).

President and CEO Cathy Zhai commented: “I am very pleased with the execution of this MOU with Odyssey, which aligns with Monument’s development strategy to enhance production potential in the Murchison region. As junior companies continue to navigate the inherent challenges and risks in the Natural Resource industry, this collaboration represents a win-win opportunity and a business model which may expand the potential mine life of the Murchison Gold Project, accelerate capital returns, and enhance free cash flow. It will also support exploration companies’ direct access to cash resources without large dilution for advancement of gold discoveries within this prolific Murchison Goldfield.”

Ms. Zhai added: “Odyssey is our joint venture partner at Tuckanarra. By integrating Tuckanarra’ s potential ore into our mine plan, we could potentially increase our production portfolio by up to 20% of Tuckanarra resources and improve the utilization of our mill capacity. Sharing technical studies and exploring this collaboration may lead to optimized production and resource exploration that benefits both parties.”

Ms. Zhai further emphasized: “In parallel, Monument remains committed to its independent technical Study with SRK Consulting and continues preparation efforts toward the potential launch of its Murchison production initiative.”

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 developing and advancing operating 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 ); 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 (Figure 1).

Odyssey’s Tuckanarra Gold Project is part of the prolific Murchison Goldfields. The Project currently has an indicated and inferred Mineral Resource Estimate of 5.14Mt @ 2.5g/t Au for 407koz of gold. This includes a high-grade subset of 2.25Mt @ 3.9g/t for 283koz of gold above a 2.0g/t Au cut off. Approximately 4.2Mt @ 2.3g/t Au for 311koz is on granted mining leases.

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

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