Great Divide Mining Ltd. (ASX: GDM) Directors recently visited the company’s Coonambula Antimony-Gold Project in Central Queensland during Dart Mining’s (ASX: DTM) initial drilling program under the current farm-in joint venture.

The visit provided GDM’s Board and senior technical team an opportunity to review site progress and preliminary geological observations first-hand. Early indications from drilling and sampling are consistent with — and in several areas exceed — expectations established from the earlier surface and in-situ sampling campaign that reported Antimony grades exceeding 65% Sb and Gold up to 17 g/t Au.

“These are still early days, and we’ll let the lab results speak for themselves,” said GDM CEO Justin Haines.

“The geology we’re seeing on the ground reinforces the scale and consistency we were hoping for at Coonambula.”

“Everything we’ve seen so far points toward a system that’s delivering on its early promise,” he said.

GDM Chairman Paul Ryan said the progress at Coonambula was impressive and validated the company’s brownfield growth model.

“Our strategy is to target proven districts with known mineral systems and re-energise them with modern exploration,” said Ryan.

“Having a proactive and technically capable joint-venture partner like Dart Mining only amplifies that success,” he said.

“Coonambula continues to demonstrate the value of our joint-venture strategy,” Haines added. “By partnering with Dart Mining, we’ve accelerated exploration in one of Queensland’s most prospective antimony and gold districts — and positioned GDM strongly as results begin to come through.”

Coonambula lies 70 km southeast of Evolution Mining’s Cracow gold mine and 25 km southwest of the Eidsvold goldfield in a historically significant mining district that has produced more than 2 million oz of gold.

“I can’t wait to be releasing full assay results,” smiles Haines.
