PRESS RELEASE: GDM First-Year Roadmap to Boost Production at Challenger Mine

Latest Press Release

Great Divide Mining Ltd (ASX:GDM) has outlined to the ASX today an ambitious first-year operational plan for the Challenger Gold Mine in Adelong, NSW, targeting a steady ramp-up to commercially sustainable levels of gold production seeking to secure long-term growth.

“The mine’s First Gold Pour on July 16, lifted GDM’s ownership to 51%,” said CEO Justin Haiines, “The company has now presented its 1st Annual Plan to the Adelong Venture Parties, setting a clear pathway from current restart works through to sustainable continuous processing.”

Great Divide Mining’s goals for the year include:

Continuous Operations: Upgrading the onsite plant to run continuously, processing mullock, spoil and tailings at commercial levels,
Mine Restart: Commencing dewatering and access to underground workings,
Exploration: Drilling and geological studies to expand resources
Community & Environment: Establishing a local Community Consultative Committee, hosting a Community Open Day, and advancing site rehabilitation and environmental monitoring.

CEO Justin Haines said, “Our plan balances ambition with pragmatism and resilient commercial realism.”

“We’ve built in the contingencies needed for an older site, but our focus is clear – moving Challenger to a sustainable production footing as quickly as possible,” said Haines.

“We’re targeting near-term cash flow while unlocking the field’s very real exploration potential,” he said.

“Equipment for the processing plant expansion has already started to arrive,” said Haines, “Specialist contractors and consultants will mobilise to site in coming weeks, with initial priorities being plant reconfiguration, metallurgical testing, and production of bulk concentrate samples to provide to potential buyers.”

The Challenger Gold Mine is part of the Adelong Project, a 70km² high-grade, underexplored goldfield with a modern processing plant. GDM operates the site under a joint venture with Adelong Gold Limited (ASX:ADG).

“We’ve done what we said we’d do. Now it’s time to give it a bit of a tune up,” smiles Haines.
