PRESS RELEASE: GDM’s Yellow Jack Project Moves Closer to Production

Latest Press Release

Great Divide Mining Ltd (ASX: GDM) has today announced to the ASX that it has decisively moved its Yellow Jack Gold Project closer to production, signing a binding term sheet with Native Mineral Resources Holdings Ltd (ASX: NMR) to form the Yellow Jack Joint Venture.

Under the agreement, GDM’s wholly owned subsidiary, GDM Yellow Jack Pty Ltd, will mine and deliver ore from its Yellow Jack site to NMR’s Blackjack Mill — located just 240 kilometres southeast via all-weather access roads — where it will be processed and refined for sale.

The partnership enables GDM to transition from explorer to producer in a low-risk, capital-efficient way, utilising existing regional infrastructure to significantly shorten timeline-to-cashflow.

GDM Chief Executive Officer Justin Haines said the agreement exemplifies GDM’s pragmatic, stepwise and yet accelerated growth strategy.

“GDM was established to move promptly from exploration to cash-flow.” said Haines.

“Partnering with NMR brings production within reach at Yellow Jack — a low-risk, capital-light path to near-term revenue,” Haines went on.

“This joint venture is a perfect fit for GDM’s brownfield focus — transforming under-utilised regional assets into producing opportunities and local jobs.”

The Yellow Jack partnership marks GDM’s third production initiative this year – first Gold pour at the Challenger Gold Mine in Adelong, NSW, and the successful Coonambula farm-in with Dart Mining (ASX: DTM).

Mr Haines added:

“We’re now in just year two since listing, and of our five projects, three have moved decisively in the right direction,” Haines said.

“I can’t wait for GDM’s first commercial cash flows,” smiles Haines.
