Everest Metals Corporation Mt Edon Rubidium Results Exceed 0.67%

Everest Metals Delivers Strong New Rubidium Results at Mt Edon

Everest Metals Corporation (ASX:EMC) has announced impressive additional drilling results from its Mt Edon Critical Mineral Project in Western Australia, reinforcing the deposit’s position as a potential global rubidium producer. The Phase 2 resource upgrade drilling programme continues to demonstrate exceptional mineralisation consistency with peak grades reaching 0.67% Rb₂O and multiple thick intersections exceeding 0.30% Rb₂O.

These latest Everest Metals Corporation Mt Edon rubidium results complement previously reported high-grade intercepts from November 2025. Furthermore, they significantly strengthen the technical understanding of Mt Edon’s rubidium mineralisation through parallel CSIRO characterisation studies.

Outstanding High-Grade Rubidium Intersections

The Phase 2 drilling programme has delivered standout results that reinforce the deposit’s high-grade nature. The consistency of these Everest Metals Corporation Mt Edon rubidium results demonstrates the project’s exceptional geological continuity.

Key Thick, High-Grade Intersections:

• • 35m @ 0.32% Rb₂O from 36m (25ME-D1) including 16m @ 0.41% Rb₂O from 43m

• • 71m @ 0.25% Rb₂O from surface (25ME-D2) including 20m @ 0.34% Rb₂O from 3m

• • 86m @ 0.26% Rb₂O from 5m (25A-25) including 15m @ 0.35% Rb₂O from 35m

• • 83m @ 0.25% Rb₂O from 2m (25A-38) including 17m @ 0.36% Rb₂O from 43m

These results showcase the remarkable consistency of mineralisation at Mt Edon, with near-surface, thick intercepts demonstrating both grade and geological continuity. Additionally, the mineralisation extends across the 500+ metre strike length, whilst the deposit remains open along strike, offering significant potential for resource expansion.

Executive Chairman Mark Caruso commented: “The drill results show remarkable consistency and reliability, strongly reinforcing the high-grade nature of the rubidium mineralisation at Mt Edon. Results from the ongoing CSIRO Rubidium characterisation programme are delivering valuable mineralogical and geometallurgical insights that will be used to refine ore beneficiation test work.”

Advanced CSIRO Mineralogical Studies Provide Processing Insights

Everest has successfully completed its CSIRO Kick-Start rubidium characterisation project, providing critical mineralogical and geochemical insights. In addition, these studies directly support development of optimised processing strategies. The comprehensive study analysed over 3,000 metres of drill samples using advanced analytical techniques.

Key CSIRO Findings:

Rubidium Distribution:

• • K-feldspar (microcline) hosts the predominant proportion of rubidium

• • Muscovite contributes significantly with approximately 0.75wt% Rb₂O

• • Lepidolite shows highest concentrations up to 1.6wt% Rb₂O plus caesium enrichment

Processing Implications:

• • Quantitative framework established for translating bulk grades into processing-relevant metrics

• • Geometallurgical model development linking pegmatite mineralogy to recoverable value

• • Minimal weathering impact on rubidium-bearing zones confirmed

• • Advanced hyperspectral analysis provides detailed mineral classification and mapping

The study demonstrated that weathering has minimal impact on the rubidium- and lithium-bearing pegmatite zones at Mt Edon. Consequently, this supports the development of reliable processing parameters for future extraction operations.

Understanding Rubidium: A Critical Battery Metal

What is Rubidium?

Rubidium (Rb) is a rare alkali metal increasingly recognised as a critical mineral for advanced battery technologies and aerospace applications. As one of the most electropositive elements, rubidium offers superior energy density characteristics compared to lithium in certain battery configurations.

Why It Matters to Investors:

• • Strategic importance: Limited global supply with growing demand from high-tech industries

• • Battery applications: Next-generation energy storage systems requiring higher energy density

• • Defence applications: Critical for specialised military and aerospace technologies

• • Supply chain security: Few operating mines globally, creating supply bottleneck opportunities

Australia currently has no commercial rubidium production, positioning Mt Edon as a potential foundation for establishing an Australian rubidium industry. Moreover, this first-mover advantage presents significant value creation opportunities for investors.

Robust Resource Foundation with Expansion Potential

Mt Edon hosts an existing Inferred Mineral Resource of 3.6 million tonnes @ 0.22% Rb₂O, containing approximately 7,900 tonnes of rubidium oxide. Within this resource, a high-grade subset of 1.3 million tonnes @ 0.33% Rb₂O contains about 4,290 tonnes of rubidium oxide, representing 56% of the total content.

Resource Characteristics:

• • Near-surface mineralisation supporting cost-effective open-pit mining

• • Low stripping ratio due to outcropping mineralisation

• • Strike length currently covers only approximately 400m within a 1.2km pegmatite corridor

• • Vertical extent tested to approximately 100m below surface with potential for deeper extensions

The Phase 2 drilling programme specifically targeted resource upgrade and expansion. Furthermore, the Everest Metals Corporation Mt Edon rubidium results are expected to significantly enhance the project’s resource base and classification in the upcoming resource update.

Strategic Development Timeline and Upcoming Catalysts

Everest has outlined a comprehensive development timeline with key milestones targeting commercial rubidium production. The systematic approach demonstrates management’s commitment to delivering value through measured development phases.

H1 2026 Milestones:
