Outstanding Final Results Confirm Geological Interpretation
The Astral Resources NL Theia deposit drilling results have delivered exceptional outcomes, with the completion of this 11,121-metre drilling programme on a tight 12-metre by 12-metre spacing providing exceptional confidence in the Stage 1 Theia open pit design. Furthermore, the latest batch of 17 holes (2,018m) delivered multiple high-grade intersections that demonstrate the consistency of gold mineralisation across the deposit.
Key highlights from the final results include:
- 21m at 7.13g/t Au from 40m including 2m at 63.8g/t Au (AMRC120)
- 43m at 2.46g/t Au from 48m including multiple high-grade zones (AMRC118)
- 28m at 3.38g/t Au from 102m including 1m at 35.0g/t Au (AMRC115)
- 33m at 2.21g/t Au from 44m including 1m at 14.3g/t Au (AMRC119)
- 19m at 1.81g/t Au from 68m and 4m at 46.8g/t Au including the spectacular 1m at 184.7g/t Au (AMRC116)

Understanding Gram x Metres: A Key Mining Metric
Gram x metres represents the product of grade multiplied by interval length, providing a measure of gold endowment per drill hole. Moreover, this metric combines both the quality of mineralisation (grade) and the quantity (interval width) into a single measurement that helps evaluate the overall metal content encountered in drilling.
The programme's average of 52.2 gram x metres per hole is exceptional and demonstrates both the consistency and high-grade nature of the Theia mineralisation. In addition, this metric helps investors understand the robustness of mineralisation – indicating a combination of good grades over meaningful widths rather than narrow high-grade intercepts that might not be economically viable at scale.
For context, gram x metres values above 20-30 are generally considered encouraging in gold exploration. Consequently, Astral's 52.2 average is particularly significant for demonstrating the deposit's mining potential.
Theia: The Foundation of Mandilla's Success
The Theia Deposit represents the cornerstone of the Mandilla Gold Project, hosting 33.3Mt at 1.1g/t Au for 1.2Moz of contained gold. Furthermore, it contributes 75% of the total 1.48Moz outlined in the Pre-Feasibility Study.
Stage 1 Development Plans:
- 4.2Mt at 1.1g/t Au for 146,000 ounces over first 21 months
- Strip ratio of 4:1 – highly favourable for early cash generation
- 80m x 120m panel now infilled to 12m x 12m spacing for mining confidence
The cross-section analysis shows strong correlation between the latest drill results and the 2025 Mineral Resource Estimate model. As a result, this validates the geological interpretation and provides confidence for mining planning.
What Makes the Theia Deposit Exceptional?
The Astral Resources NL Theia deposit drilling results confirm several key characteristics that set this deposit apart from typical gold discoveries. For instance, the consistent high-grade mineralisation across the entire deposit footprint demonstrates exceptional geological continuity.
The deposit's shallow depth and favourable geometry create optimal conditions for open pit mining. However, it's the combination of grade, continuity, and metallurgical characteristics that truly distinguishes Theia as a world-class starter pit opportunity.
Multiple Exploration Programmes Advancing in Parallel
Beyond Theia, Astral is maintaining momentum across multiple fronts. For instance, several concurrent programmes are advancing the overall project development timeline.
Diamond Drilling Programme Completed:
- 7 holes for 2,423 metres testing the "230 shear" structure and eastern mineralisation
- Visual examination confirms intensely sheared structures with assays pending
Theia West Development:
- 9 of 11 RC holes completed testing 120-metre spacing between previous intercepts
- Programme ongoing with strike and infill testing
Feysville Gold Project:
- 17-hole programme (2,954m) completed at Kamperman Deposit
- Testing high-grade footwall mineralisation and parallel vein systems
- Results pending and expected to enhance the project economics
How Do These Programmes Support Overall Development?
The strategic approach to multiple concurrent programmes maximises exploration efficiency whilst maintaining focus on the primary Theia development. Furthermore, each programme targets specific geological opportunities that could enhance the overall project economics.
The systematic approach ensures that the Astral Resources NL Theia deposit drilling results remain the foundation whilst building additional value through targeted exploration at satellite deposits.
Robust Resource Base Supporting Development
Astral's consolidated position across three key projects provides exceptional scale and development optionality. In addition, the diversified resource base reduces single-asset risk whilst maximising operational synergies.
| Project | Indicated Resources | Inferred Resources | Total Resources |
|---|---|---|---|
| Mandilla | 31Mt @ 1.1g/t (1.03Moz) | 11Mt @ 1.1g/t (392koz) | 42Mt @ 1.1g/t (1.43Moz) |
| Feysville | 4Mt @ 1.3g/t (144koz) | 1Mt @ 1.1g/t (53koz) | 5Mt @ 1.2g/t (196koz) |
| Spargoville | 2Mt @ 1.3g/t (81koz) | 1Mt @ 1.6g/t (58koz) | 3Mt @ 1.4g/t (139koz) |
| Group Total | 36Mt @ 1.1g/t (1.26Moz) | 14Mt @ 1.2g/t (502koz) | 50Mt @ 1.1g/t (1.76Moz) |
Ore Reserve Estimate:
- 36.6Mt @ 0.9g/t for 1.08Moz providing 12+ year mine life
- Based on conservative $3,000/oz gold price assumption
Investment Thesis: World-Class Location, Exceptional Economics
The Mandilla Gold Project's location in Western Australia's premier Kalgoorlie region positions it alongside world-class operations. For instance, it sits near the Golden Mile Super Pit, St Ives Gold Mine, and Beta Hunt Gold Mine. Consequently, this infrastructure-rich environment provides significant operational advantages.
Key Investment Highlights:
- Exceptional starter pit economics with 4:1 strip ratio at Theia Stage 1
- Proven metallurgy with high gravity recoverable gold and fast leach kinetics
- No third-party royalties beyond standard WA Government gold royalty
- Definitive Feasibility Study progressing for completion in 2025
Pre-Feasibility Study Economics (June 2025):
- $1.4 billion NPV8 at $4,250/oz gold price
- $2.9 billion NPV8 at $6,250/oz gold price
- 95koz annual production for first 12 years
- 2.75Mtpa processing facility supporting seven open pit mines
What Sets This Project Apart from Competitors?
The combination of location, resource quality, and proven metallurgy creates a compelling investment proposition. However, it's the exceptional starter pit economics that truly differentiate this opportunity from other gold development projects.
The Astral Resources NL Theia deposit drilling results have systematically de-risked the project whilst demonstrating consistent high-grade mineralisation. Furthermore, the infrastructure advantages and established mining jurisdiction reduce development risk significantly.
