Brightstar Resources has announced positive drilling results from its Lord Byron deposit in Western Australia – boosting confidence in supporting upcoming expansion and an increase in mineral resource estimate (MRE).
Part of the Goldfields hub, hosting a MRE of 1.6 million ounces (Moz) at 1.6 grams per tonne (g/t), drilling has intersected wide zones of high-grade material.
Brightstar completed 22 drill holes for approximately 2000m of drilling across two “modest” drilling programs in late 2025 designed to infill and extend the southern extension of the Lord Byron deposit.
Results from the second drilling campaign, completed in October, targeted down-dip and down-plunge extensions to the company’s newly highlighted southern lobe and included results of 9m at 3.49 g/t gold from 138m, including 1m at 24.7 g/t gold from 142m and 4m at 6.71 g/t Au from 128m, including 1m at 19.6g/t Au from 129m.
This has seen a six per cent increase in total mineral resource – now sitting at 5.4 million tonnes at 1.5 g/t gold for 267,000 ounces – as well as both measures and indicated mineral resources.
This is now 122,000 ounces at 1.6 g/t gold: an eight per cent jump.
“We are pleased to report the latest drilling intercepts from the Lord Byron deposit and associated mineral resource update. The drilling is rapidly delineating the shallow extension which remains open to the south,” Brightstar managing director Alex Rovira said.
“Exploration drilling programs in2026 will focus 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.”
The “relatively modest” upgrades in mineral resource has increased the confidence of the Lord Byron hub – which remains fully approved for mining operations to begin this year.
