• Brightstar completes 22 RC drill holes at Lord Byron deposit
• Drilling results include high-grade intercepts up to 24.7g/t Au
• Mineral Resource Estimate updated with 6% increase to 267koz

Brightstar Resources Ltd has received results from reverse circulation (RC) drilling completed at the Lord Byron deposit in 2025, part of the 1.6Moz @ 1.6g/t Au Goldfields Hub. The drilling was designed to infill and extend the southern extension of the Lord Byron deposit. Significant intercepts include 9m @ 3.49g/t Au from 138m, including 1m @ 24.7g/t Au, and 4m @ 6.71g/t Au from 128m, including 1m @ 19.6g/t Au. The drilling results have been included in an updated Mineral Resource Estimate, which shows a 6% increase in Total Mineral Resource to 5.4Mt @ 1.5g/t Au for 267koz, and an 8% increase in Measured & Indicated Mineral Resources to 122koz @ 1.6g/t Au. The company plans to focus exploration drilling in 2026 on targeting the lode along strike to the south and at depth, as well as testing early-stage targets for comparable mineralisation beneath shallow cover.

Brightstar continues to advance the Goldfields Hub asset base towards a Final Investment Decision in the MarQ'26, with technical work for the Goldfields DFS2.0 nearing completion including updated mine plans, an increased mill throughput scenario delivering improved gold production output and financial metrics.
