Great Divide Mining (GDM) has started commercial production at its Challenger gold mine in New South Wales following a successful commissioning phase.
The company has now transitioned to steady-state operations, with ongoing processing of historic tailings material to continue.
The restart is notably distinct from traditional mining. GDM’s current strategy focuses on processing historic tailings material using modern recovery techniques and existing infrastructure.
This brownfield approach has allowed the company to bypass the massive capital expenditure and environmental disturbance typically associated with opening a new mine.
Analytical testing during the commissioning phase has confirmed the system’s performance, with GDM confident the site can consistently produce gold concentrate targeting grades of 30 grams per tonne.
Preparations are now in the final stages for the first shipment of gold concentrate, which is scheduled to be dispatched to a refining partner within the coming days.
The move to commercial production follows a series of community engagement sessions where the company pledged to revitalise the local industry.
Great Divide Mining CEO Justin Haines said the achievement validates the company’s disciplined business model.
“Challenger demonstrates the commercial rigour of GDM’s strategy – bringing brownfield assets back into commercial production in a disciplined and capital-efficient manner,” Haines said.
“This approach allows us to de-risk our project pipeline for investors while, at the same time, minimising environmental disturbance.”
As production ramps up, GDM intends to establish a regular shipment schedule.
The phased recommissioning serves as a blueprint for the company’s broader project pipeline, proving that legacy assets can be successfully repurposed to support Australia’s modern resources sector.
