Lightning Minerals Uncovers Tungsten Potential at Warby — A Critical Mineral Discovery Hidden in Plain Sight
Lightning Minerals Limited (ASX: L1M) has announced the identification of significant tungsten potential at its 100%-owned Warby Project in North Queensland, adding a compelling new dimension to a project area previously known primarily for its gold and copper prospectivity. The Lightning Minerals Warby tungsten discovery in North Queensland emerges from a review of historical regional drainage sampling data, field reconnaissance, and on-ground mineralisation observations — all pointing to an underexplored tungsten system that has seen no modern systematic exploration.
The announcement reveals that historical drainage sampling returned tungsten values of up to 102 parts per million (ppm W) from active stream sediment samples, whilst visible tungsten mineralisation has been observed in quartz vein, greisen, and altered granite material during field activities completed in May 2026. Fourteen rock chip samples have been collected from dump material across nine individual vein positions and submitted to ALS Laboratories in Townsville, with results expected within approximately two weeks.
"The identification of visible tungsten mineralisation associated with historical workings at Warby represents a highly encouraging outcome for the Company and reinforces the broader potential emerging across this underexplored project area. Importantly, the combination of anomalous historical drainage results, visible mineralisation, greisen alteration and structural setting provide a strong technical foundation as we advance our understanding of the project. With tungsten prices strengthening significantly amid tightening global supply conditions and increasing focus on securing alternative Western supply chains, we believe Warby is well positioned to emerge as a compelling exploration opportunity within Lightning Minerals' North Queensland portfolio." — CEO Troy Brice
The discovery confirms multiple shallow historical workings across a 2-kilometre northwest-trending structural corridor, with greisen alteration identified between mapped vein positions. This suggests potential for a broader mineralised system beyond isolated vein occurrences. The Warby Project sits approximately 25 kilometres north of Mount Surprise in North Queensland.

A Geological Setting That Delivers the Right Conditions
The tungsten target area sits at a geologically favourable contact zone — the boundary between the Permo-Carboniferous I-type Elizabeth Creek Granite and the Proterozoic Lyndbrook Metamorphic Complex. This type of intrusive contact is a well-recognised geological setting for tungsten mineralisation globally, particularly for the greisen-hosted and vein-related styles observed at Warby.
The structural corridor hosting the workings trends northwest over approximately 2 kilometres, suggesting a system of meaningful lateral extent. Dense vegetation and limited outcrop exposure mean that additional workings or extensions may remain concealed beneath surface cover — a characteristic the Company views as potential upside rather than a limitation.
The shallow historical workings are interpreted to date from the World War One era, reflecting early-stage, artisanal extraction that left the broader system largely untouched by modern exploration techniques. Visible mineralisation includes coarse sprays of acicular wolframite in quartz, accompanied by malachite and limonite gossan — mineralogical associations consistent with a primary tungsten system.
| Geological Feature | Significance | Observation at Warby |
|---|---|---|
| Intrusive Contact Zone | Favourable for tungsten formation | Elizabeth Creek Granite/Lyndbrook Metamorphic boundary |
| Structural Corridor | Indicates system continuity | 2km northwest-trending zone |
| Historical Workings | Confirms mineralisation | WW1-era shallow pits across corridor |
| Wolframite Mineralisation | Primary tungsten ore mineral | Visible in quartz vein material |
Understanding Greisen Alteration: The Key Technical Discovery
One of the more technically significant observations in the Lightning Minerals Warby tungsten discovery in North Queensland is the identification of greisen alteration between mapped vein positions. For investors less familiar with geological terminology, understanding what this means provides crucial insight into the project's potential scale.
What Is Greisen Alteration?
Greisen represents a type of rock formed when hot, mineral-rich fluids — typically associated with cooling granite intrusions — chemically alter the surrounding rock. The process replaces original minerals with a characteristic combination dominated by quartz and mica minerals, and is commonly associated with the deposition of tin and tungsten minerals, including wolframite and scheelite.
Why Does Greisen Matter at Warby?
The presence of greisen alteration between vein positions suggests the mineralising system extends beyond narrow, discrete veins. Instead, it may represent a more pervasive, volume-hosted mineralised zone — the type of system that, if confirmed by assay results, could offer substantially greater resource potential than simple vein counting would imply.
Furthermore, this geological observation elevates the Lightning Minerals Warby tungsten discovery in North Queensland from isolated vein targets to a potentially broader mineralised system with enhanced economic prospects.
| Term | Definition | Relevance to Warby |
|---|---|---|
| Greisen | Altered granite rock enriched in quartz and micas | Observed between veins, suggesting broader system |
| Wolframite | Primary tungsten ore mineral (iron-manganese tungstate) | Visually identified in quartz vein material |
| Acicular | Needle-like crystal habit | Describes visible wolframite crystal form |
| Stream Sediment Sampling | Geochemical sampling of active drainage channels | Method used to identify initial 102 ppm W anomaly |
From Historical Anomaly to Active Exploration Target
The pathway from anomaly identification to active sampling demonstrates methodical, evidence-driven exploration practice. The sequence of events has moved quickly and systematically.
Historical data review identified tungsten values of up to 102 ppm W in regional drainage sampling, flagging the area as a priority reconnaissance target. Field reconnaissance subsequently confirmed multiple historical shallow workings distributed along a 2-kilometre structural corridor.
Mineralisation observation confirmed visible tungsten mineralisation — specifically wolframite — in quartz vein, greisen, and altered granite material from historical dump material. The current sampling programme comprises 14 rock chip samples collected from nine vein positions and submitted to ALS Laboratories in Townsville.
Assay results are expected within approximately two weeks, providing the first modern quantitative characterisation of tungsten tenor and distribution across the prospect. This structured approach means the next data release represents an immediate and near-term catalyst for investors following this story.
Tungsten: A Critical Mineral at a Critical Moment
The timing of this discovery sits against a meaningful backdrop for tungsten as a commodity. Tungsten is classified as a critical mineral by several Western governments, reflecting its strategic importance across industrial manufacturing, infrastructure, and defence applications — including cutting tools, drill bits, armour-piercing ammunition, and advanced alloys.
Global tungsten supply has come under increasing scrutiny following export restrictions imposed by China, which remains the dominant global supplier of processed tungsten products. This has prompted a broader industry and government focus on securing alternative tungsten supply from stable jurisdictions.
Key Supply and Demand Dynamics
- China accounts for the overwhelming majority of global tungsten production and processing
- Export restrictions have tightened processed tungsten availability in international markets
- Demand is forecast to grow, driven by industrial activity, infrastructure investment, and defence-related procurement
- Exploration for tungsten in stable Western jurisdictions has attracted renewed interest as supply chain diversification becomes a higher priority
The Company notes that whilst these broader market dynamics provide a favourable backdrop, the Warby Project remains at an early exploration stage. The announcement does not make claims about the project's potential to contribute to supply chains or receive any specific form of government support.
Warby Within the Broader Lightning Minerals Portfolio
The tungsten target adds a new layer to what is already a diversified North Queensland exploration portfolio. Lightning Minerals' primary focus remains the Mt Turner Gold Project, its flagship asset in northern Queensland, which hosts a large-scale gold system extending over approximately 14 kilometres of strike along the prospective Drummer Fault.
Ongoing drilling at Mt Turner is aimed at progressing toward resource definition. In addition, the identification of tungsten potential at Warby is positioned as additional upside beyond the Company's core gold and copper focus — representing an expansion of the value proposition across already-held, underexplored tenure.
| Asset | Location | Primary Commodity | Status |
|---|---|---|---|
| Mt Turner Gold Project | North Queensland | Gold | Flagship — active drilling, resource definition focus |
| Warby Project | ~25km north of Mt Surprise, NQ | Gold, Copper + Tungsten (new) | Early-stage — assays pending |
| Lachlan Fold Belt Projects | New South Wales | Gold, Copper | Pipeline exploration assets |
| Eastern Goldfields Projects | Western Australia | Gold | Pipeline exploration assets |
The fact that no modern systematic exploration has previously been conducted within the tungsten target area means this represents genuinely new ground — a characteristic that is increasingly rare in well-explored Australian jurisdictions.
Near-Term Catalysts and Expected Milestones
The immediate pipeline of activity and expected milestones from the Warby tungsten programme provides clear and near-term visibility for investors.
Assay results from 14 rock chip samples are expected within approximately two weeks of the announcement date, representing the first modern quantitative data from the prospect. Results will inform the Company's understanding of tungsten grade and spatial distribution across the nine sampled vein positions.
Depending on assay outcomes, follow-up work could include more systematic rock chip sampling, soil sampling programmes, or geophysical surveys to test the broader 2-kilometre structural corridor. The potential for additional concealed workings or extensions beneath vegetation cover suggests the mapped area may not represent the full extent of the system.
"The assay results due within two weeks represent the most immediate catalyst for investors tracking this story. These will provide the first modern quantitative validation of the visual mineralisation observations and historical drainage anomalies."

Investment Considerations for Lightning Minerals
Lightning Minerals presents a clear multi-commodity exploration story with an expanding opportunity set across a 100%-owned, Tier 1 jurisdiction tenure position. The Lightning Minerals Warby tungsten discovery in North Queensland adds genuine optionality to an asset base that was already advancing on its primary gold focus at Mt Turner.
What Makes the Current Moment Noteworthy?
Several factors combine to create a compelling near-term narrative:
- Unexplored ground with historical validation — WW1-era workings confirm historical activity, but the absence of modern exploration means the project represents essentially a blank canvas for systematic evaluation
- Greisen alteration between veins provides a potentially significant indicator of a broader, volume-hosted system rather than narrow, isolated veins
- Near-term data catalyst — assay results due within approximately two weeks provide an immediate information flow event
- Critical mineral commodity context — tungsten's classification as a critical mineral and the supply dynamics created by Chinese export restrictions provide relevant backdrop for exploration in stable jurisdictions
Importantly, the tungsten work represents incremental opportunity rather than dilution of the primary focus — the Mt Turner Gold Project drilling programme continues as the Company's flagship priority.
The combination of geological setting, alteration signatures, historical activity, and near-term assay results provides a coherent technical and commercial story. This positions Lightning Minerals as a company to watch within the critical minerals and North Queensland exploration space.
