• Fish underground mine now fully established as Brightstar's second high-grade underground operation
• Discovery of Northern Fault Offset Lode at Second Fortune presents material in-mine exploration upside
• Ore production ramping up at Fish with first ore mined and hauled for processing

Brightstar Resources Ltd (ASX: BTR) has provided an operational update for the June 2025 quarter from its Second Fortune and Fish underground operations located in the Company's Laverton Hub. The June 2025 quarter represented a period of sustained steady-state operations at Second Fortune that delivered a 25% increase in production rate from the March quarter. New opportunities have been identified to add increased ounces per vertical metre to the operation through a targeted drill-out of the newly discovered 'FTV Lode', to the north of the Second Fortune Main Lode. The presence of economic widths and grades of mineralisation beyond the northern fault presents as an attractive in-mine exploration target for Brightstar. At the Fish underground mine, over 500m of twin boom jumbo development has been completed, including Decline and capital development. The access to the first ore drive, the 1350 level, was excavated in late June, marking a key step forward for the Fish operations team with stoping to occur later in the current quarter. Surface exploration drilling is ongoing at Fish, with a total of eight (8) drillholes planned, totalling 2,600m, targeting infill and life-of-mine extensions.

The Company remains focused on growing its production profile in line with its recently announced 'TARGET200' strategy, targeting +200koz p.a. within 5 years.

Brightstar will continue to provide updates on production and exploration results from its Laverton operations as they become available. The Company anticipates further ramp-up in production at Fish during the September 2025 quarter, alongside the progression of drilling programs at both Fish and Second Fortune to support targeted Mineral Resource upgrades and mine life extensions.
