Mandilla Gold Project by Astral Resources Delivers 95,000oz Annual Production

Astral Resources: Building a Multi-Decade Gold Producer in the Heart of Kalgoorlie

Astral Resources (ASX: AAR) is advancing its flagship Mandilla Gold Project toward becoming Western Australia's next significant gold producer, with the potential to deliver 95,000 ounces of gold annually for more than a decade.

Pre-Feasibility Study Reveals Robust Economics and Long-Term Growth Potential

The recently completed Pre-Feasibility Study (PFS) for the Mandilla Gold Project has unveiled compelling financial metrics that position Astral as one of the most promising emerging gold developers in Australia.

Based on a conservative gold price of A$4,250/oz, the project boasts:

• 95,000 ounces annual gold production for the first 12 years
• A$1.4 billion pre-tax NPV (8% discount)
• A$2.8 billion pre-tax free cashflow
• 12-month payback period

At today's gold price of approximately A$5,000/oz, these metrics improve dramatically to a A$2.0 billion pre-tax NPV and A$3.9 billion in pre-tax free cashflow, with payback reduced to just 9 months.

"The Mandilla PFS demonstrates the outstanding economic potential of our flagship project, with metrics that stand up strongly even at conservative gold price assumptions," says Marc Ducler, Managing Director of Astral Resources. "This puts us on a clear path to becoming a significant gold producer in one of Australia's premier mining jurisdictions."

Premium Location in Australia's Golden Heartland

The Mandilla Gold Project enjoys a strategic position in Western Australia's world-renowned Kalgoorlie goldfields, approximately 70km south of Kalgoorlie and just 25km from the well-established mining town of Kambalda.

This prime location provides exceptional infrastructure advantages:

• Proximity to the Coolgardie-Esperance Highway (less than 500m)
• Access to established power, water and gas infrastructure
• Available local workforce and services in nearby Kambalda
• Efficient access to processing and transportation infrastructure

Growing Resource Base Underpins Long-Term Production

Astral has built an impressive resource base across three emerging hubs, with the Mandilla Gold Project by Astral Resources as its cornerstone:

The company has demonstrated remarkable efficiency in resource conversion, with 95% of the Mandilla resource and 86% of the Feysville resource incorporated into the PFS production target. This has resulted in a substantial maiden Probable Reserve of 1.1 million ounces (36.6Mt at 0.9g/t gold).

Theia Deposit: The Crown Jewel

The cornerstone of the Mandilla Project is the substantial Theia deposit, which represents 81% of the Mandilla resource with 33Mt at 1.1g/t gold for 1.2 million ounces contained in a single large open pit.

Recent high-grade diamond drilling results at Theia have been exceptional:

• 1m at 223.3g/t gold
• 9.55m at 27.6g/t gold
• 2.42m at 169.1g/t gold
• 24.9m at 4.14g/t gold

Current infill drilling is further validating the resource model with impressive intercepts including:

• 32m at 10.8g/t gold from 50m
• 2m at 95.9g/t gold from 105m
• 9m at 5.1g/t gold from 62m

Accelerating Development Timeline

Astral is advancing the Mandilla Gold Project by Astral Resources on a well-defined development pathway:

• Submit regulatory approvals: Q4 2025
• Definitive Feasibility Study completion: Q2 2026
• Final Investment Decision: July 2026
• Construction commencement: Q3 2026
• First gold production: Q4 2027

The project will utilize conventional open-pit mining methods with a simple processing flowsheet, benefiting from excellent metallurgical recoveries of 95.5%.

Satellite Projects Enhance Economics

The nearby Feysville Gold Project, located just 14km south of Kalgoorlie, will serve as a satellite operation feeding ore to the Mandilla processing facility. With a maiden Probable Reserve of 88,000 ounces (2.3Mt at 1.2g/t gold), Feysville is expected to contribute approximately A$250 million in free cash flow to the overall project economics.

The recently acquired Spargoville tenements not only optimize the Mandilla Gold Project by Astral Resources infrastructure layout but also add 139,000 ounces of gold resources with significant exploration upside. Initial drilling has returned promising results, including:

• 26m at 2.0g/t gold from 111m
• 20m at 1.4g/t gold from 43m

Understanding Mineral Resources vs. Ore Reserves

For investors new to the mining sector, it's important to understand the difference between Mineral Resources and Ore Reserves:

Mineral Resources represent concentrations of mineralization with reasonable prospects of eventual economic extraction. They are classified based on increasing geological confidence as Inferred, Indicated, or Measured.

Ore Reserves are the economically mineable part of Measured and/or Indicated Mineral Resources. They include diluting materials and allowances for losses that may occur during mining, and are classified as either Probable or Proved Ore Reserves.

Astral's ability to convert 95% of its Mandilla Mineral Resource to the production target demonstrates the high quality and economic viability of its resource base.

Why Investors Should Watch Astral Resources

Astral Resources presents a compelling investment case for several key reasons:

1. Advanced-stage gold project with robust economics even at conservative gold price assumptions
2. Significant scale with annual production of 95,000 ounces for 12 years and a total mine life of 18.5 years
3. Strategic location in the heart of Western Australia's premier gold mining district with excellent infrastructure
4. Substantial resource base of 1.8 million ounces with strong conversion to reserves
5. Clear development pathway to production with major milestones over the next 24 months
6. Exploration upside across three project hubs with ongoing drilling programs
7. Experienced management team with a track record of bringing mines into production

For investors seeking exposure to the gold sector through a well-advanced development project in a tier-1 jurisdiction, Astral Resources represents one of the most compelling opportunities on the ASX. With significant de-risking already achieved through the PFS and ongoing resource definition, the company is positioned to become Australia's next significant gold producer in an environment of strong gold prices.

"Astral is the only ASX aspiring gold developer with a project of this scale in the Kalgoorlie/Kambalda region," notes Marc Ducler, "giving investors a unique opportunity to participate in the development of a long-life gold operation in Australia's most established gold mining district."
