Cashflow from historic mine waste at GDMs Challenger-Mine
Great Divide Mining Ltd (ASX:GDM) (“GDM” or “the Company”) is pleased to advise that the Company is expanding the scale of recovery and processing of historic surface mine waste at its Challenger Gold Mine near Adelong, NSW.
The Company has recently completed reconstruction of historical site access infrastructure to commence mineralised mine waste recovery operations at the historic Currajong waste emplacement area, with recovery and processing now occurring on a daily basis.
On 30 April 2026, GDM successfully shipped its first load of gold concentrate from Challenger, marking a key operational milestone in the recommissioning of the mine.
The newly accessible material at Currajong consists of historically dumped mineralised mine waste generated by previous operators. Based on current observations and historical site activity, GDM believes the area contains a significant quantity of commercially valuable gold-bearing material suitable for sustainable recovery and processing.
Surface recovery operations also provide valuable commissioning data, operator training and process optimisation opportunities ahead of larger-scale underground mining activities
GDM is currently undertaking further assessment work to estimate the total tonnage and recoverable gold content contained within the now exposed waste area.
“At today’s gold prices, historic mine waste is no longer waste — it is a valuable resource,” said GDM Chief Executive Officer Justin Haines.
“The ability to generate cash flow from surface material enables GDM to fast-track Challenger toward sustainable operations ahead of the commencement of full mining activities.”
“It is a commercially sound decision to bring cash flows forward as early as possible in a project’s life, particularly where the material is already sitting on surface and readily accessible.”
“Importantly, while recovering value for shareholders, GDM is also progressively cleaning up historic mine waste areas across the site.”
“This was a commitment we made to the Adelong community at our recent Community Information Evening, and we are pleased to now be delivering on it in a practical and measurable way.”
The Challenger Gold Mine recommissioning program continues to progress under the Company’s staged “crawl-walk-run” operational strategy, with surface processing activities providing operational experience, early revenue generation, and further validation of the broader Challenger project.
“This is better than the classic WIN:WIN … At GDM’s Challenger mine, our Shareholders win, the Adelong Community wins, and the Environment wins as well,” smiles Haines.
