Great Divide Mining (ASX:GDM) is transitioning to steady-state operations and commercial production after completing commissioning at its Challenger gold mine in New South Wales through these last few months.

Commissioning has been supported by analytical laboratory testing of processed ore, confirming system performance and providing confidence in process optimisation and product quality.
Challenger is processing historic tailings material, and based on commissioning outcomes, CEO Justin Haines says the company is confident in the site’s ability to consistently produce gold concentrate targeting grades of 30 grams per tonne.
“At GDM’s recent community information evening and community open days, we promised to deliver an operating gold mine at Challenger. We’ve now delivered for the community and for all shareholders and investors,” Mr Haines said.
“Challenger demonstrates the commercial rigour of GDM’s strategy – bringing brownfield assets back into commercial production in a disciplined and capital-efficient manner.
“This approach allows us to de-risk our project pipeline for investors while, at the same time, minimising environmental disturbance.”
Dispatch of the shipment of the first gold concentrate is scheduled in the coming days to an established refining partner.
“This milestone represents a significant step in the rapid recommissioning of the Challenger Mine, achieved within a compressed timeframe and without the need for large-scale capex or new mining activity,” Mr Haines said.
“The company’s phased approach to recommissioning – utilising existing infrastructure, processing historic tailings, and applying modern recovery techniques — continues to underpin both operational performance and environmental outcomes.”
In December, GDM announced an update on Challenger Mine development plans to suit a sole-funded development, optimisation and operation.
Mr Haines said when the Challenger operations were suspended in August, GDM had already commenced works towards the next stage of operations.
This included works to transition the Challenger plant to a continuous gravity recovery operation only using water.
GDM is down -1.45%, to 34¢. Mkt cap $23.44M.
