Right Resources Confirms High-Grade Tungsten Discovery at Blue Prospect Tumbarumba

Right Resources Confirms High-Grade Tungsten at Blue Prospect — A Critical Minerals Discovery Worth Watching

Right Resources Limited (ASX: RRE) has delivered a compelling exploration result from its Tumbarumba tenements in New South Wales, confirming high-grade tungsten mineralisation at the newly identified Blue Prospect. Rock chip assays have returned grades of up to 4.3% WO₃ (tungsten trioxide), while systematic soil sampling has outlined a coherent multi-element anomaly spanning 2.1 km x 1.8 km — and the anomaly remains open in all directions.

For a company that only recently brought this prospect to light through methodical regional exploration, the Right Resources Blue Prospect high grade tungsten discovery at Tumbarumba NSW represents a significant step forward in building a critical minerals portfolio alongside its flagship gold project.

From Forest to Discovery: How Blue Prospect Was Found

Blue Prospect was not a chance find. It emerged from the disciplined application of the Company's Reduced Intrusion-Related Gold System (RIRGS) exploration model, developed in collaboration with CODES — the Centre for Ore Deposit and Earth Sciences at the University of Tasmania, one of the world's most respected independent ore deposit research institutions.

The RIRGS model predicts a characteristic metal zonation pattern around intrusion-related hydrothermal systems, with tungsten and bismuth expected to occur in proximal positions close to the heat source. What has been observed at Blue Prospect is precisely consistent with this prediction.

An initial field programme conducted between February and April 2026 covered systematic soil sampling on an approximate 200 m x 200 m grid, geological mapping, and rock chip collection — all completed within a recently planted pine forest in the Green Hills State Forest near Tumbarumba, NSW.

During a February 2026 site visit, Dr Francisco Testa of CODES independently confirmed the presence of scheelite within quartz veins at multiple outcrop and subcrop locations. He also identified what appears to be traces of bismuthinite under hand lens. This third-party scientific verification strengthens the credibility of the discovery at an early stage.

Initial CODES analysis of the broader Tumbarumba district geological framework is currently being received by the Company and will be released to the market following review.

The Numbers: What the Assays Actually Show

All 35 rock chip samples collected from the Blue Prospect were submitted to a certified laboratory and have passed QAQC standards. The standout result — sample RTRK_00269 — returned 34,600 ppm tungsten, equivalent to 4.3% WO₃, placing it firmly in high-grade territory by global standards.

The table below presents a selection of notable assay results from the programme:

It is important to note that the highest-grade samples identified in the field based on portable XRF readings were not selectively prioritised for certified assay — they have instead been submitted to CODES for further testwork. This means the certified assay dataset may not yet fully reflect the upper end of grade potential at the prospect.

Furthermore, rock chip results are selective surface samples and are not necessarily representative of average mineralisation across the broader prospect area. They confirm the presence of high-grade tungsten mineralisation within the defined anomaly and justify systematic follow-up work.

A Soil Anomaly That Keeps Growing

Systematic portable XRF (pXRF) soil sampling using an Olympus Vanta V2MR analyser — with five readings taken per sample and results averaged — has defined a coherent tungsten-bismuth-molybdenum soil anomaly measuring 2.1 km x 1.8 km.

The coincident enrichment of tungsten, bismuth, and molybdenum across the same spatial footprint is geologically meaningful. In intrusion-related systems of this style, this metal association is a strong indicator of proximity to a fertile hydrothermal centre.

Notably, the anomaly is open in all directions and is interpreted to extend westward onto Exploration Licence EL9889, which was granted in April 2026 and covers the interpreted western extension of the system. Additional soil sampling is ongoing to define the full extent.

What the Geology Is Telling Us

Geological mapping at Blue Prospect has defined a well-developed sheeted vein system comprising quartz-dominant and locally brecciated veins hosted within a sheared and altered intrusive sequence. Individual veins are typically up to 0.4 m thick, forming sheeted vein arrays of 20 m to greater than 70 m width across the prospect.

Vein systems trend between 230° and 280° within what appears to be a quasi-circular shaped tungsten soil anomaly, ringed by molybdenum enrichment — a textbook pattern for this style of intrusion-related mineralisation.

Multiple tungsten mineral species have been confirmed at surface, supporting a primary hydrothermal origin:

• Scheelite (CaWO₄) — the primary ore mineral for tungsten, confirmed by UV fluorescence and pXRF; independently verified by CODES researchers
• Wolframite ((Fe,Mn)WO₄) — a key primary tungsten ore mineral
• Tungstite (WO₃.H₂O) — interpreted secondary tungsten mineral from field observations
• Meymacite (WO₃.2H₂O) — interpreted secondary tungsten mineral
• Stolzite (PbWO₄) — interpreted secondary tungsten mineral, suggesting potential supergene enrichment

The presence of both primary ore minerals alongside secondary tungsten oxide minerals is consistent with a well-developed hydrothermal system that has subsequently experienced surface oxidation — a feature that can indicate enrichment near surface.

Understanding Tungsten Trioxide: What Is WO₃ and Why Does It Matter?

Tungsten is not reported in the same way as gold or copper. Rather than quoting the pure metal content directly, the industry standard is to express tungsten grades as WO₃ — tungsten trioxide — because this is the form in which tungsten is most commonly measured, processed, and sold.

The conversion is straightforward: 3.4% W (pure tungsten) equals approximately 4.3% WO₃.

When investors compare tungsten deposits globally, WO₃ is the common language. A grade of 4.3% WO₃ from a rock chip sample is considered high-grade in the context of tungsten exploration and is comparable to grades found at some of the world's notable tungsten deposits.

Why Tungsten Matters: The Strategic Context

Tungsten sits at the intersection of defence, advanced manufacturing, and the energy transition — sectors experiencing substantial structural demand growth. China currently controls approximately 85% of global tungsten supply, a concentration that has drawn significant attention from Western governments seeking to diversify critical mineral supply chains.

Tungsten is classified as a critical mineral by both the Australian Government and the United States Department of Interior. The Australian Government has, furthermore, included tungsten in its Critical Minerals Strategic Reserve. Demand from the defence sector is expected to increase materially in the near term, driven by increased global military spending.

The metal's unique properties — extreme hardness, the highest melting point of any element, and high density — make it irreplaceable in:

• Defence applications — armour-penetrating ammunition, missile components
• Advanced manufacturing — cutting tools, drill bits, wear-resistant coatings
• Mining equipment — hard-rock drilling and crushing components
• Electronics — semiconductors, X-ray tubes, electrical contacts
• Renewable energy — wind turbine components and energy storage systems

For Australian explorers, the combination of a stable mining jurisdiction, existing critical minerals frameworks, and growing Western demand for non-Chinese supply creates a structurally supportive environment for tungsten discovery and development.

What Comes Next: The Exploration Roadmap

Right Resources has outlined a clear sequence of follow-up activities to advance the Blue Prospect from discovery to drill-ready target. The programme is methodical and designed to build confidence in the system before committing drilling capital.

The granting of EL9889 in April 2026 is particularly significant. It secures ground over the interpreted western extension of the anomaly, meaning the full footprint of the system is now held by the Company and the exploration programme can proceed without tenure constraints in that direction.

The Investment Thesis: A Critical Minerals Dimension Added to a Gold Explorer

Right Resources entered the market as a gold-focused explorer, anchored by the Pilot Project — a high-grade gold target in the Tumbarumba region with a history of high-grade underground production of approximately 38 g/t Au, currently being advanced through a maiden diamond drilling programme also in collaboration with CODES.

The Right Resources Blue Prospect high grade tungsten discovery at Tumbarumba NSW adds a material critical minerals dimension to what is now a diversified exploration portfolio across 2,518 km² of tenements in the Tumbarumba and New England regions.

What Makes This Discovery Stand Out?

Several features of this announcement stand out from an investment perspective:

1. Grade quality at surface. A rock chip result of 4.3% WO₃ is high-grade by the standards of tungsten exploration globally. While rock chips are selective samples and do not represent average deposit grade, they confirm the presence of a fertile mineralised system at the earliest stage.

2. Scale of the anomaly. A coherent 2.1 km x 1.8 km multi-element soil anomaly open in all directions indicates a large-scale mineralised system — not a narrow isolated vein. The true extent has not yet been defined.

3. Independent scientific verification. CODES confirmation of scheelite in the field provides credibility that goes beyond typical exploration announcements. CODES is internationally regarded, and its involvement in both the exploration model development and on-ground verification is a differentiating factor.

4. Model-driven discovery. The fact that Blue Prospect was identified through a systematic geological model — not luck — suggests the Company's exploration methodology has predictive power that may be replicable across its broader tenement package.

5. Tenure secured. With EL9889 granted in April 2026 covering the interpreted western extension, the Company holds ground over the full anticipated system footprint.

6. No drilling yet required to generate significant news. The programme to date has been surface-based and relatively low-cost. The transition to drilling, when permitting is secured, represents the next major potential re-rating catalyst.

"These results validate our geological model and provide confidence that the Company's systematic exploration approach can generate significant discoveries in what has been a relatively under-explored part of the Tumbarumba district," said Graham Howard, Managing Director of Right Resources Limited.

Why Investors Should Keep Watching Right Resources

Right Resources is at an early but genuinely exciting stage of exploration at Blue Prospect. The combination of high-grade surface results, a large open-ended soil anomaly, multiple tungsten mineral species confirmed in outcrop, and independent scientific verification from CODES creates a compelling foundation for what comes next.

The pipeline of upcoming catalysts is, in addition, particularly meaningful:

• Release of initial CODES analysis of the Tumbarumba district — providing independent geological interpretation of the broader system
• Ongoing soil sampling results — expected to extend and potentially enlarge the defined anomaly
• Early-stage metallurgical testwork — providing initial data on tungsten recovery characteristics
• Drill permitting progress — moving the project toward its first subsurface test
• Continued advancement of the Pilot gold project — maintaining the dual-commodity exploration story

However, investors should note that exploration at this stage carries inherent uncertainty, and surface results do not guarantee continuity at depth. The Right Resources Blue Prospect high grade tungsten discovery at Tumbarumba NSW has identified a high-grade, large-scale tungsten system confirmed by independent scientists from one of the world's leading ore deposit research institutions.

With a 2.1 km x 1.8 km anomaly open in all directions, grades of up to 4.3% WO₃ at surface, and a clear pathway toward drilling, investors have multiple near-term catalysts to monitor. In a global environment where tungsten supply security is an increasingly urgent strategic priority, early-stage discoveries of this scale in stable jurisdictions deserve close attention.

Rock chip results are selective surface samples and are not necessarily representative of average mineralisation across the broader prospect area and should not be relied upon as an indication of bulk grade or mineralised tonnage.
