Operational Update

Goldstone Resources Limited (AIM: GRL), the West African gold producer and developer, is pleased to provide an update on its Homase Mine and heap leach operation in south-western Ghana ("Homase").

• Latest Gold Pour: gold production continues to progress encouragingly, with 11.06 kilograms of gold doré, equivalent to approximately 355.6 ounces of gold doré poured during the w/c 18 August 2025.
• Expansion continues: plans to expand the heap leach continues to progress, with civil engineering design complete, and awaiting construction permit, and geotextile and geomembrane liner ordered and paid for, with anticipated delivery by the end of September 2025.
• Maintaining volumes and production: the Company continues to focus on delivering 48,000 tonnes of agglomerated stacked ore per month, which, together with moving back into the Pit 1, with a continued average grade of 1 g/t, is expected to maintain the Company's production profile through the remaining months of 2025.

Emma Priestley, Chief Executive Officer, commented:

"The collective determination of our technical team and board continues to translate into steady progress at Homase. While the pace has been slower than we would have hoped, operations and gold production remain on a positive trajectory and we are all fully aligned and committed to delivering on our production goals. I look forward to updating shareholders over the coming weeks and months as we work to build further momentum through the remainder of 2025."
