Highlights

Brightstar commenced a seven-hole, approximately 6,500m deep drilling program at Two Mile Hill on 28 October 2026.
The program follows a reported 305m intercept grading 1.33g/t gold below the existing mineral resource.
An A$82 million institutional placement includes a A$30 million commitment from Genesis Minerals.
The Sandstone pre-feasibility study and updated Two Mile Hill resource were targeted for the December 2026 quarter.
Goldfields construction remained on budget and on schedule for first gold in the June 2027 quarter.

Brightstar Resources Limited (ASX:BTR) is a Western Australian gold developer advancing the Goldfields and Sandstone project hubs. Its October announcements brought together new exploration activity at Two Mile Hill and additional equity funding intended for Sandstone development. Brightstar Resources (ASX:BTR) also reaffirmed its separate Goldfields construction timetable.

Two Mile Hill Drilling Expands the Geological Test

On 28 October 2026, Brightstar Resources (ASX:BTR) announced that the first of two rigs had started a seven-hole diamond drilling campaign of approximately 6,500m at the Two Mile Hill-Shillington deposit. The program aims to test the Shirvington Zone along strike and at depth, assess mineralisation below the current resource boundary, and better define the western edge of the host tonalite.

The company reported a current Two Mile Hill-Shillington Mineral Resource Estimate of 24.6 million tonnes grading 1.8 grams per tonne gold, containing approximately 1.45 million ounces. This is a mineral resource, not a statement of economically recoverable ore. Previous drilling returned 305m at 1.33g/t gold from 584m, including 173m at 1.42g/t below the resource estimate.

Assays from three other deep holes were outstanding as of the 28 October announcement. Brightstar said the new and pending results would inform an updated resource estimate and the Sandstone pre-feasibility study, both targeted for the December quarter.

Placement Provides Funding for Sandstone Work

A day earlier, Brightstar Resources (ASX:BTR) announced binding commitments for an A$82 million placement before costs, comprising 164 million new shares at A$0.50 each. Genesis Minerals subscribed for A$30 million, or 60 million shares, with an expected post-placement interest of approximately 5.4%.

The stated use of proceeds includes infill and extensional drilling, testing adjacent targets, advancing an underground exploration decline, preparing site infrastructure and supporting further feasibility work. Settlement was expected on 2 November 2026, with the new shares scheduled to commence trading on 3 November. Brightstar said the Sandstone study would transition into a definitive feasibility study after the planned pre-feasibility release.

Goldfields Progress Remains a Separate Milestone

The 27 October company announcement described Goldfields construction as on schedule and on budget, with the Laverton processing plant approximately 47% complete. First gold was targeted for the June 2027 quarter. Brightstar Resources (ASX:BTR) stated that Goldfields was funded through its earlier 2026 equity raising and US$120 million senior secured bond. Bond proceeds were dedicated to Goldfields, not Sandstone.

Execution and Funding Considerations

Exploration results may not convert into a larger classified mineral resource or a viable mine plan. The deeper tonalite boundary remains incompletely defined, further assays are pending, and the resource and study updates have not yet been delivered. The placement introduces additional shares, while future Sandstone construction decisions depend on technical work and funding requirements. Goldfields remains exposed to plant construction, commissioning and schedule execution, notwithstanding the company’s October status update. Gold price changes can also affect future project economics.

Key Insights

Brightstar Resources (ASX:BTR) has advanced a defined drilling program and secured commitments for Sandstone-focused capital while continuing Goldfields construction. The near-term evidence will come from pending assays, an updated Two Mile Hill resource and the Sandstone study. These disclosures document project progress but do not establish the eventual production scale, project economics or cause of any particular trading movement.
