Brightstar Resources (ASX: BTR) Hits 305m of Gold at Sandstone as 5.2Moz Resource Base Strengthens Growth Potential

Brightstar Resources Limited (ASX: BTR) has delivered another encouraging exploration milestone, intersecting 305 metres of gold mineralisation at its Sandstone Gold Project in Western Australia.

The discovery strengthens the company's position as an emerging Australian gold producer, with approximately 5.2 million ounces in mineral resources across its portfolio and first gold production targeted for June 2027.

With exploration success accelerating alongside mine development, Brightstar is building a stronger foundation for long-term production growth.

Key Numbers

• 305m at 2.66g/t gold: Standout drilling intercept from 503m depth at Two Mile Hill.
• 4m at 60.8g/t gold: High-grade interval, including 0.9m at 241g/t.
• 1.45 million ounces: Existing Two Mile Hill-Shillington mineral resource grading 1.8g/t gold.
• 5.2 million ounces: Approximate group mineral resource inventory, including 3.6Moz at Sandstone.
• $82 million: Strategic capital raising announced in October 2026 to support exploration and development.

The Latest Development: A Significant Step Forward at Sandstone

Brightstar's 12 November drilling results have reinforced the potential for substantial resource expansion at Two Mile Hill.

Diamond drillhole TMHDD26005 returned 305m at 2.66g/t gold, including 4.1m at 26.1g/t and 5.5m at 25.2g/t.

The result represents the company's strongest Sandstone intercept on a grade-times-width basis, exceeding 800 gram-metres.

Another hole, TMHDD26004, intersected 80m at 2.64g/t and 240m at 1.16g/t, including 43m at 3.49g/t.

Importantly, mineralisation extends below the existing resource boundary, suggesting that Two Mile Hill could contain additional gold beyond its currently defined inventory.

The host tonalite also extends more than 400m across at depth, strengthening the geological case for continued exploration.

Further drilling will be required to establish resource continuity and economic extraction potential.

What Stands Out to Us

Brightstar's growing resource inventory offers considerable development flexibility.

The Two Mile Hill-Shillington resource increased 98% in September 2026 to 1.45Moz, and the latest drilling suggests further expansion remains possible.

This exploration momentum comes alongside improving financial capacity.

At 30 September, Brightstar held $58.7 million in unrestricted cash and $161.4 million in restricted bond proceeds allocated to Goldfields development.

The subsequent $82 million placement, including a $30 million commitment from Genesis Minerals, provides additional funding capacity.

While the raising introduces shareholder dilution, it also strengthens Brightstar's ability to advance exploration without immediately relying on operating cash flow.

The key opportunity is converting this expanding resource inventory into economically viable production.

What the Company Is Doing Now

Brightstar is progressing two complementary growth priorities.

At Goldfields, construction of the 1.5-million-tonne-per-annum Laverton processing plant remains on schedule and within budget.

Engineering reached 90% completion in October, while construction-related earned value reached 50%.

The company has also acquired a 223-room accommodation camp and commenced grade-control drilling at the Lord Byron open pit.

First gold remains targeted for June 2027, with planned annual production of approximately 75,000 ounces from FY2028 over an initial six-year mine life.

Meanwhile, a two-rig, approximately 6,500m drilling program continues at Sandstone.

Together, these activities position Brightstar to pursue near-term gold production while developing a potentially larger second operation.

Insight: Is Brightstar Building a Stronger Foundation for Long-Term Gold Production?

We see Brightstar's combination of growing mineral resources, strengthened funding and advancing mine construction as an encouraging development story. The latest Sandstone drilling adds credibility to its exploration potential, while Goldfields provides a defined pathway towards initial revenue and operating cash flow. Importantly, the company's larger resource inventory could offer future production flexibility as development studies progress. Although deeper mining costs and execution risks remain important considerations, successful Goldfields commissioning and favourable Sandstone feasibility results could materially strengthen Brightstar's longer-term commercial outlook.

What Happens Next?

The next exploration milestone is the outstanding assay result from diamond hole TMHDD26006.

Additional drilling and an updated mineral resource estimate could provide further evidence of Two Mile Hill's scale.

The Sandstone pre-feasibility study will also help establish development costs, production potential and project economics.

At Goldfields, the targeted June 2027 first gold pour represents the company's most important near-term operational catalyst.

With substantial resources, encouraging exploration results and mine construction progressing, Brightstar is moving closer to becoming a producing Australian gold company.

The next phase will determine how effectively that growing asset base can translate into sustainable production, cash generation and long-term shareholder value.
