Astral Resources' Breakthrough Metallurgical Results Unlock Outstanding Gold Recoveries at Feysville Deposits
In a highly promising development, Astral Resources (ASX: AAR) has announced exceptional metallurgical test results from its wholly-owned Feysville Gold Project near Kalgoorlie. The Kamperman deposit has returned outstanding gold recovery rates of 98.1%, showcasing excellent potential for low-cost, high-recovery gold processing.
Key Highlights at a glance:
- Unprecedented gold recoveries of up to 98.1% achieved at Kamperman deposit
- Rogan Josh deposit demonstrates strong recoveries averaging 91.5% at coarse grind size
- Maiden Mineral Resource Estimates:
- Kamperman: 2Mt @ 1.3g/t Au for 83.8koz
- Rogan Josh: 0.7Mt @ 1.3g/t Au for 27.4koz
- Results pave way for integration of Feysville as high-value ore sources into upcoming Mandilla Pre-Feasibility Study (Mandilla PFS), due this Quarter
Metallurgical Results Breakdown:
| Deposit | Number of Samples Tested | Avg. Gold Recovery (%) | Grind Size (µm) | Avg. Cyanide Consumption (kg/t) |
|---|---|---|---|---|
| Kamperman¹ | 5 | 98.1% (Three Sections) | 150 | 0.41 |
| Kamperman² | 2 | 87.9% (Copper Affected) | 150 | 1.10³ |
| Rogan Josh | 2 | 91.5% | 150 | 0.06 |
¹ Three representative samples.
² Copper-affected samples, expected to receive higher recoveries upon retesting.
³ Higher cyanide consumption due to copper presence.
Astral Resources' Managing Director Marc Ducler commented:
"These metallurgical test results clearly demonstrate that the simple, low-cost processing pathway being pursued in the Mandilla PFS will also be suitable for processing Feysville ore. Our intention is clear—we'll incorporate Feysville deposits as high-grade satellite ores, significantly adding value to our proposed 2.5Mtpa Mandilla process plant."
Investors' Guide: What is Metallurgical Testing?
Metallurgical Testing is a key stage in mineral project evaluation. It involves laboratory analysis of mineral samples to determine how effectively a mineral—such as gold—can be extracted and recovered from its ore.
Why it Matters to Investors:
- High metallurgical recoveries (like the 98.1% obtained by Astral) indicate better potential profitability, lower processing costs, and improved project economics
- Metallurgical test results impact project valuations significantly, affecting investment returns and overall mine feasibility
- Metallurgy directly informs the chosen processing technology—a substantial component of both capital and operational expenditure
Glossary of terms:
- Free-Milling: Ore type that typically yields high gold recoveries using conventional gravity and cyanidation methods
- Grind Size (P80): The particle size at which 80% of the material is finer; indicative of energy requirements for grinding
- Cyanidation: Gold extraction process using dilute cyanide solution
Robust Forward Momentum: Clear Growth Path & Upcoming Catalysts
Astral Resources is moving efficiently forward, with clearly outlined project timelines and development milestones:
- Immediate Retesting of copper-affected samples at Kamperman to push recovery above 90%
- Mandilla Pre-Feasibility Study Completion scheduled within current quarter
- Upcoming Drilling Results for Feysville and Mandilla projects expected in near-term
Project Milestones for Investors:
| Timeline | Milestone | Location |
|---|---|---|
| Current Quarter | Completion of PFS integrating Feysville results | Mandilla Project |
| Later This Month | Assay results from recent air-core drilling | Feysville Project |
| June Quarter | Reverse Circulation drilling results | Feysville/Mandilla |
| Following RC at Mandilla | Commencement of Spargoville RC drilling program | Spargoville Project |
Investment Thesis: Why Astral Resources Deserves Investors' Attention
Astral Resources' Feysville project now offers highly competitive metallurgical results alongside a significant resource profile. This places the company in a strategic growth position among its regional peers, situated in a Tier-1 mining jurisdiction near significant regional deposits such as the KCGM Super Pit and St Ives Gold Mine.
Astral vs Regional Peer Comparison:
| Metric | Astral Resources (Feysville) | Peer Average (Regional WA) |
|---|---|---|
| Gold Recovery (%) | 98.1% (Kamperman) | ~90-94% |
| Indicated Resource Grade | 1.3 g/t Au | ~1.0-1.3 g/t Au |
| Cyanide Consumption (kg/t) | 0.41 kg/t (average) | ~0.5-0.8 kg/t |
Astral is clearly leading in terms of recovery and cost-efficiency metrics, highlighting exciting upside and investor potential.
