Drilling Push at Key Prospects

At the Hacks West prospect, located around 2km west of the historical Hacks Mine — which previously produced approximately 200,000 ounces of gold at an exceptional grade of 24 grams per tonne (g/t) — drilling has revealed standout results. Intercepts such as 1 metre at 38.3g/t gold underscore the high-grade potential of this area.

Further south, the Havilah Camp prospect has delivered encouraging down-plunge extensions. The team targeted mineralisation beyond a previously reported hit of 3 metres at 11.4g/t from 129 metres. This earlier intercept, notably absent from the existing 54,000-ounce gold resource at Havilah, has now been supplemented by recent drilling and is set to be included in Brightstar's updated resource estimates.

Meanwhile, at the Bulchina prospect, drilling has focused on strike extensions to the south of the main deposit. Historically, Bulchina has produced around 230,000 ounces at 3.62g/t gold, and the shallow historical drilling results now provide a compelling case for renewed exploration in this corridor.

Systematic Strategy to Unlock Resource Upside

Brightstar is employing a dual-track strategy — conducting both infill and step-out drilling — aimed at uncovering new mineralised zones while enhancing confidence in existing resources. The latest results from Hacks West, Havilah, and Bulchina support this approach, revealing high-grade intercepts even in early-stage drilling campaigns.

The company views Havilah as the most advanced among the three, with plans to integrate new drilling data into its upcoming Mineral Resource Estimate (MRE) update. Hacks West and Bulchina, while at earlier stages, have shown promising signs that they could evolve into substantial assets within the broader Sandstone Hub portfolio.

Brightstar sees considerable untapped potential in the region, and its ongoing exploration activities suggest the current resource base could be just the beginning. The consistent results from key target areas position the company well for future growth through resource upgrades and project development at Sandstone.
