Below is a detailed breakdown of the data, figures, and tables in the Red Mountain Mining (RMX) Armidale Antimony-Gold Project announcement.
1. Project Overview & Key Insights
Project Scope
- Project Name: Armidale Antimony-Gold Project
- Location:Southern New England Orogen, NSW, Australia
- Exploration License:EL9732 (Covers 391 km²)
- Minerals Targeted:Antimony (Sb), Gold (Au), Tungsten (W)
- Current Stage:Early-stage exploration, initial sampling phase
✅ Positive Aspects
- Large-scale tenement (391 km²) within Australia’s premier antimony province.
- Proven historical mining activity (antimony & gold) supports the area’s perspectivity.
- Exploration is well-planned (1,300+ soil and rock chip samples planned).
- Structural geology is promising—fault-related mineralization increases the likelihood of economic deposits.
❌ Negative Aspects
- No existing JORC-compliant resource estimate—means the project is still highly speculative.
- Historical workings were small-scale—raises concerns about whether significant deposits exist.
- No modern drilling has been conducted—current data relies on historic workings and assumptions.
2. Geology & Mineralization
Geological Setting
- Hosted within the Southern New England Orogen (SNEO).
- Antimony occurs in hydrothermal quartz veins, breccias, and stockworks.
- Gold is associated with stibnite in carbonate breccias.
- Major structures: Peel Fault, Namoi Fault, Cobadah Fault.
✅ Positive Aspects
- Structural traps (fault zones) provide a good setting for mineralization.
- Gold-antimony association is geologically favorable, as seen in other deposits like Hillgrove.
- Underexplored region—historical focus was on gold, not antimony.
❌ Negative Aspects
- Lack of drilling data—No deep testing of structures.
- No metallurgical data—Unclear how recoverable antimony and gold are from the host rocks.
3. Sampling Program & Data Analysis
Planned Sampling
- Total Samples:1,300+ rock chip & soil samples.
- Sample Sites:
- Oaky Creek – Twin historical stibnite workings.
- East Hills – Stibnite-bearing reef.
- Horsley Station – Gold-bearing quartz reef.
3.1 Oaky Creek – Antimony Workings
Key Features
- Two historic antimony workings (100 years old).
- Located 2 km apart, along Namoi Fault.
- Hosted in carbonate breccia & altered sandstone.
- Trace gold reported.
Sampling Plan
- 1,025 soil samples planned.
- 100m line spacing, 50m sample intervals.
✅ Positive Aspects
- Presence of historical workings confirms antimony mineralization.
- Large sampling grid (4 x 1.2 km block) ensures comprehensive coverage.
❌ Negative Aspects
- Age of workings (100 years) raises concerns about previous economic viability.
- No previous drilling data available for deeper structures.
- Only "trace" gold detected—not enough evidence for a gold resource.
3.2 East Hills – Antimony Shaft
Key Features
- Stibnite-bearing reef with a strike of 170°.
- Lies parallel to Peel Fault and Cobadah Fault.
- Hosted in metasedimentary rocks.
Sampling Plan
- 88 soil samples planned.
- 500 x 600m grid, 100m line spacing, 50m sample interval.
✅ Positive Aspects
- Structural setting is promising—fault-related mineralization increases chances of a large system.
- High-priority target due to its proximity to known antimony deposits.
❌ Negative Aspects
- Sample grid is relatively small (500 x 600m)—may not be large enough to define a major resource.
- No clear evidence of high-grade gold.
3.3 Horsley Station – Gold and Stibnite Prospect
Key Features
- Historical small-scale gold workings.
- Gold reef is 3m wide, strikes 010° over 10m.
- Associated with Peel Fault.
Sampling Plan
- 233 soil samples planned.
- 100m line spacing, 50m sample intervals.
✅ Positive Aspects
- Known gold occurrence—historical production supports further work.
- Peel Fault-associated mineralization is promising.
❌ Negative Aspects
- Small-scale historical workings suggest limited gold tonnage.
- Limited sampling (233 samples) may not fully define mineralization extent.
4. Structural & Geophysical Context
Major Structural Features
- Peel Fault System: 400 km long, associated with numerous gold and base metal occurrences.
- Namoi & Cobadah Faults: Parallel splays off Peel Fault.
Comparison with Hillgrove Antimony-Gold Mine
- RMX suggests similarities between Armidale and the Hillgrove Gold-Antimony Mine (ASX: LRV).
- Hillgrove is a proven deposit, producing >700,000 oz of gold & 50,000t of antimony.
- Armidale has a similar setting but lacks defined resources.
✅ Positive Aspects
- High structural complexity supports potential mineralization.
- Underexplored—potential for undiscovered deposits.
❌ Negative Aspects
- RMX is implying a similarity to Hillgrove, but no direct evidence yet.
- No drilling to confirm the presence of economic antimony/gold deposits.
5. Economic Considerations
Antimony Market Outlook
- Antimony is a critical mineral used in batteries, flame retardants, and alloys.
- China dominates global antimony supply, raising demand for new sources.
Gold Market Outlook
- Gold remains strong at ~$2,900/oz.
- Gold-antimony association is economically attractive.
✅ Positive Aspects
- Critical mineral status could attract government incentives for development.
- Demand for battery metals supports potential value.
❌ Negative Aspects
- RMX has no current economic model for the project.
- Viability depends on defining a resource, which is not yet done.
6. Risks & Challenges
Key Risks
Exploration Stage Risk
- No JORC-compliant resources yet.
- Project remains speculative until drilling confirms economic mineralization.
Historic Workings Were Small
- Previous miners only developed small shafts & pits.
- This suggests deposits may not be large-scale.
Metallurgical Uncertainty
- No data on antimony/gold recovery rates.
- Processing complexity (arsenic, refractory ores) could be an issue.
Funding & Timeline
- No announced budget for future drilling.
- Project progression depends on securing financing.
Final Verdict: Investment Risk & Potential
Category Score (Out of 5) Geological Potential 4.0 Exploration Progress 2.5 Resource Definition 1.5 Economic Viability 2.5 Infrastructure & Access 3.0 Overall Score 2.7 / 5 (Moderate to High Risk) Final Conclusion
- Strong geological potential, but lacks drilling confirmation.
- Antimony’s market relevance is a key advantage.
- The project needs deeper testing & financial backing before becoming viable.
- Investors should expect a long exploration timeline with high risks.
