Brightstar Resources has delivered exceptional drilling results from its Sandstone Gold Project, with standout intercepts demonstrating the substantial scale and grade potential of this 2.4Moz @ 1.5g/t Au resource. These Brightstar Resources Sandstone Gold Project results include remarkable intercepts such as 411m @ 1.11g/t Au at the Two Mile Hill-Shillington deposit, feeding directly into the company's upcoming mineral resource estimate (MRE) update due in June 2026 and the Pre-Feasibility Study (PFS) targeted for delivery in the second half of 2026.
Exceptional Results Define Scale and Grade Potential
The latest drilling program has delivered remarkable intercepts across multiple deposits within the Sandstone Hub. Furthermore, these results demonstrate the project's substantial scale and grade potential across several key areas.
Two Mile Hill-Shillington Deposit Highlights
SND25-001 delivered the standout result with 411.2m @ 1.11g/t Au from 80m, incorporating several high-grade zones:
- 22.7m @ 3.02g/t Au from 267.3m
- 11m @ 3.10g/t Au from 392m
- 2.0m @ 41.3g/t Au from 425m
- 2.4m @ 12.8g/t Au from 487m
In addition, SNRD25-001 intersected 162.3m @ 1.38g/t Au from 140m, including:
- 1m @ 70.5g/t Au from 140m
- 18m @ 3.07g/t Au from 234m
Moreover, SND25-003 returned 147.7m @ 1.01g/t Au from 355m, with 12.3m @ 3.60g/t Au from 459m.
High-Grade Results at Whistler and Lord Nelson
The 120koz Au Whistler deposit delivered impressive intercepts:
- 31m @ 5.17g/t Au from 126m, including 10m @ 10.6g/t Au
- 13m @ 3.54g/t Au from 113m, including 4m @ 8.79g/t Au
At Lord Nelson, results included:
- 16m @ 1.49g/t Au from 131m, including 2m @ 5.86g/t Au
- 12m @ 1.35g/t Au from 162m

Understanding Tonalite-Hosted Mineralisation
What is Tonalite?
Tonalite is a type of intrusive igneous rock, similar to granite but with different mineral compositions. At Two Mile Hill, this late-stage intrusive rock body hosts gold mineralisation within sheeted quartz veins – essentially a network of gold-bearing quartz veins running through the rock mass.
Why This Matters for Investors
Tonalite intrusions often create large, bulk-tonnage deposits suitable for underground mining. The sheeted vein system at Two Mile Hill spans approximately 400m in strike length and 100m width. Consequently, mineralisation remains open at depth, with current drilling defining mineralised tonalite beyond 725m below surface.
Strategic Positioning and Development Timeline
Current Project Status
| Metric | Details |
|---|---|
| Total Resource | 2.4Moz @ 1.5g/t Au |
| Two Mile Hill Resource | 664koz @ 1.6g/t Au |
| Active Drilling | 4 rigs (2x RC, 2x DD) |
| Distance to Processing Plant | 2.5km from Two Mile Hill |
Upcoming Catalysts
- Mineral Resource Estimate Update – June 2026
- Pre-Feasibility Study – 2H 2026
- Continued Extensional Drilling – Ongoing
Managing Director Alex Rovira commented:
"The latest drill results from the Sandstone project clearly highlight how the potential scale is developing. The Two Mile Hill-Shillington deposit is shaping up to be a significant contributor to a future Sandstone operating hub. With high grade zones within a lower grade halo up to 400m wide, the drilling illustrates the substantial extent of the mineralisation delineated to date."
Investment Thesis: Multi-Hub Gold Production Strategy
Brightstar's Consolidated Gold Portfolio
| Hub | Resource (koz) | Grade (g/t Au) | Status |
|---|---|---|---|
| Laverton | 873 | 1.7 | Production target Jun-Q'27 |
| Menzies | 718 | 1.5 | Development planning |
| Sandstone | 2,439 | 1.5 | PFS in progress |
| Total | 4,030 | 1.5 | Multi-hub strategy |
Key Investment Differentiators
Existing Infrastructure Advantage:
Brightstar owns the processing plant at Sandstone. Furthermore, Two Mile Hill is located just 2.5km from plant site and is positioned for bulk-tonnage underground mining operation.
Scale and Grade Combination:
The deposit features broad mineralised zones up to 400m wide. In addition, high-grade zones exist within lower-grade haloes and remain open at depth with significant expansion potential.
Near-Term Catalysts:
- June 2026: Updated MRE incorporating latest drilling
- 2H 2026: Pre-Feasibility Study completion
- Ongoing: Extensional drilling targeting further growth
Geological Continuity Supports Resource Growth
The latest Brightstar Resources Sandstone Gold Project results demonstrate excellent geological continuity across the Sandstone Hub.
Historical Context
Previous drilling at Two Mile Hill included impressive intercepts:
- 508.3m @ 1.38g/t Au (MSDD156)
- 372.7m @ 1.52g/t Au (TDD034)
Current Program Validation
The new results validate and extend these historical intercepts, confirming:
- Geological continuity across the deposit
- Grade consistency within mineralised zones
- Depth extension potential beyond current drilling
