Everest Metals Delivers Outstanding High-Grade Rubidium Results Ahead of Resource Upgrade
Everest Metals Corporation Ltd (ASX: EMC) has delivered exceptional new drilling results from its Mt Edon Critical Mineral Project in Western Australia, confirming the presence of robust high-grade rubidium mineralisation. The Everest Metals Corporation rubidium results set the stage for a significant resource upgrade in Q1 2026.
The latest Phase 2 resource upgrade drilling programme has exceeded expectations, with peak assays reaching 0.79% Rbâ‚‚O. Furthermore, multiple thick, high-grade intersections demonstrate the continuity and scale potential of this world-class rubidium deposit.
Standout High-Grade Intersections Confirm Resource Quality
The Phase 2 drilling programme has delivered impressive results across over 2,500 metres of drilling. Notably, all 19 reverse circulation holes intersected pegmatite mineralisation. The consistency of these Everest Metals Corporation rubidium results validates the deposit's geometry and grade distribution.
Key high-grade intersections include:
| Hole ID | Interval (m) | Grade (% Rbâ‚‚O) | Notable Features |
|---|---|---|---|
| 25A-9 | 120m @ 0.22% | 0.22% from surface | Including 26m @ 0.40% from 82m |
| 25A-19 | 92m @ 0.26% | 0.26% from surface | Including 28m @ 0.33% from 70m |
| 25A-16 | 84m @ 0.28% | 0.28% from 26m | Including 25m @ 0.33% from 42m |
| 25A-30 | 82m @ 0.22% | 0.22% from surface | Continuous mineralisation |
| 25A-18 | 68m @ 0.31% | 0.31% from 59m | Including 14m @ 0.40% from 68m |
The drilling has also confirmed exceptional associated critical mineral grades. For instance, peak lithium results reached 5.7% Liâ‚‚O over 1m. Additionally, caesium grades reached 0.63% Csâ‚‚O over 1m, highlighting the multi-commodity potential of the deposit.
"These results from the resource-upgrade programme confirm the continuity and integrity of the previously defined grades and highlight the potential for resource expansion," said Executive Chairman and CEO Mark Caruso. "While we await the remaining assay results to update the Mt Edon MRE next quarter, significant metallurgical, leaching and purification test work is underway, along with the preparation of a mining operation proposal."
Understanding Rubidium: A Critical Mineral Driving Next-Generation Technologies
Rubidium is classified as a critical mineral by the United States, New Zealand, and Japan. This alkali metal plays an essential role in advanced technological applications. Moreover, it commands premium pricing at approximately £935 per kilogram for rubidium carbonate, reflecting its scarcity and strategic importance.
Key applications driving demand include:
- Defence and aerospace: Night vision systems, atomic clocks for GPS navigation, ion propulsion engines
- Electronics: Photovoltaic cells, fibre optic technologies, specialty glass manufacturing
- Medical: Pharmaceutical production, sedatives, epilepsy medications
- Industrial: Catalysts for ammonia synthesis, hydrogenation reactions
The global rubidium market is projected to grow from $3.6 billion in 2023 to $5.8 billion by 2032. This represents a compound annual growth rate of 5.48%. However, supply constraints rather than lack of demand currently limit market size, presenting significant opportunities for new producers.
What Makes Rubidium Valuable?
Rubidium is one of the lightest metals and highly reactive, making it perfect for specialised applications where other materials cannot perform. In addition, its ability to easily release electrons makes it essential for photovoltaic cells and electronic devices.
Comprehensive Development Programme Accelerating Toward Production
Everest Metals has established a clear pathway to becoming Australia's first producing rubidium operation. Furthermore, multiple workstreams are advancing simultaneously toward production readiness.
Geometallurgical and Recovery Studies
The company is conducting extensive mineralogical and metallurgical studies through partnerships with leading research institutions:
- CSIRO collaboration: Advanced HyLogger measurements, quantitative XRD, and LA-ICP-MS analysis to characterise rubidium distribution
- Fremantle Metallurgy: Bench-scale beneficiary testwork focusing on mica separation and rubidium enrichment
- Epiroc core scanning: Hyperspectral mineral identification and textural analysis
Initial test work at Edith Cowan University has achieved 97% rubidium recovery rates. Additionally, the company holds a provisional patent for its proprietary Direct Rubidium Extraction (DRE) process.
Mining Development and Approvals
With a granted Mining Lease (M59/714) already in place, Everest Metals has commenced preparation of mining proposal documentation:
- High-resolution aerial drone survey completed for 3D modelling
- Baseline environmental, flora and fauna surveys completed
- Geotechnical studies and material characterisation in progress
- Mining Proposal submission targeted for late Q1 2026
- Approvals anticipated during H2 2026
Investment Thesis: First-Mover Advantage in Critical Mineral Production
Everest Metals is uniquely positioned to capitalise on the growing rubidium market through several key competitive advantages. The Everest Metals Corporation rubidium results demonstrate the quality and scale of the opportunity.
| Investment Highlight | Strategic Advantage |
|---|---|
| Resource Scale | 3.6Mt @ 0.22% Rbâ‚‚O containing ~7,900 tonnes Rbâ‚‚O |
| High-Grade Subset | 1.3Mt @ 0.33% Rbâ‚‚O containing ~4,290 tonnes Rbâ‚‚O |
| Mining Readiness | Granted Mining Lease with near-surface mineralisation |
| Technical Innovation | Proprietary extraction process with 97% recovery rates |
| Market Position | Positioned to become Australia's first rubidium producer |
The deposit's near-surface nature supports cost-effective open-pit mining with low stripping ratios. Meanwhile, the strike length of over 500 metres demonstrates significant expansion potential beyond the current resource envelope.
Strategic Partnerships and Funding Support
The company has secured multiple strategic partnerships and funding sources:
- US Defence Industrial Base Consortium membership providing access to non-dilutive financing
- MRIWA Innovation Grant supporting pilot plant development
- University research partnerships advancing extraction technology
