Production Continues to Ramp Up at Homase Mine

Goldstone Resources Limited (AIM: GRL) is pleased to provide an update on its Homase Mine and heap leach operation in south-western Ghana.

• Gold Pour: The Company achieved another increase in production, with 18.629 kilograms of gold doré, equivalent to approximately 598.9 ounces of gold doré poured as at 24 March 2025, a 14% monthly increase.
• Operational Ramp-Up: The operation maintains the average 48,000 tonnes of agglomerated stacked ore per month, with mining operations and heap leach processing targets on track.
• Expansion in Progress: The preparatory work continues for the expansion of Pit 1, with the pushback of the benches to allow access to the ore. It is anticipated that mining operations will re-commence in Pit 1 this month, where expected grades are 1-1.2 g/t, which with increased stacking and the continued improvement in leach kinetic rates is expected to facilitate the achievement of our production target over the coming months.

To further support the expansion of both mining and processing operations throughout 2025, operations continue to advance on the second lift of pads 3 and 4 and the extension to Cell 5 is nearing completion, with compacting completing ready for the geomembrane to be laid. The civil engineering work continues for the construction of Cells 6 and 7. The photographs shared below (Figures 1-4) provide a snapshot of this progress.
