Lightning Minerals Phase 2 Assays Extend Warby Tungsten Mineralisation With Grades Up to 5.46% W
Lightning Minerals Limited (ASX: L1M) has reported another set of high-grade rock chip assay results from its 100%-owned Warby Tungsten Project in North Queensland, with five of six samples returning more than 1.00% tungsten and a top result of 5.46% W. The Phase 2 program also extended known mineralised veins to the southeast and returned a notable gold-tin-tungsten association, adding considerable geological interest to the project.
For investors, the update matters because it strengthens the case that Warby hosts a broader mineralised system than first indicated in Phase 1. However, it remains early-stage exploration, and the company has clearly stated that rock chip samples from historical dump material are selective and not necessarily representative of in-situ grade, continuity, or scale.
Even so, repeated high-grade surface results across multiple areas can help guide the next stage of trenching, mapping, and eventual drill targeting.
"The Phase 2 rock chip assay results represent another important step in our systematic evaluation of the Warby Tungsten Project, confirming the high-grade tungsten mineralisation identified during Phase 1, with five of the six samples returning more than 1.00% tungsten and a peak result of 5.46% tungsten," said Troy Brice, Managing Director.
Brice added that the current work has "extended known mineralised veins to the southeast" and that the company is now focused on combining the remaining soil and drainage assays with Phase 2 field data to refine Phase 3 exploration and potential future drill targets.

What the Phase 2 Assay Results Show
Lightning collected six rock chip samples from six areas, including historical artisanal dump sites. These samples returned strongly anomalous tungsten values and, importantly, confirmed the tenor of results first reported in Phase 1.
The headline numbers are straightforward. Five of the six samples exceeded 1.00% W, while the highest result, sample 106165, assayed 5.46% W from milky white vein quartz containing abundant coarse wolframite blades up to 3 centimetres.
Phase 2 Rock Chip Assay Results
| Sample No. | Easting (mE) | Northing (mN) | Au (ppm) | Sn (ppm) | W (ppm) | W (%) | Lithology |
|---|---|---|---|---|---|---|---|
| 106161 | 189,992 | 8,028,264 | 2.22 | 2,100 | >10,000 | 1.31 | Brecciated quartz vein |
| 106162 | 189,523 | 8,027,793 | 0.12 | 977 | >10,000 | 1.56 | Brecciated quartz vein |
| 106163 | 189,677 | 8,027,871 | 0.08 | 234 | 1,560 | <0.20 | Brecciated milky white vein coated by malachite |
| 106164 | 189,321 | 8,027,993 | 0.08 | 37 | >10,000 | 3.46 | Milky white vein quartz with coarse wolframite blades to 2cm |
| 106165 | 189,390 | 8,027,748 | 0.03 | 4 | >10,000 | 5.46 | Milky white vein quartz with abundant coarse wolframite blades to 3cm |

The consistency of tungsten grades across several separate sample sites is one of the more relevant points in the update. While selective sampling does not define a resource, repeated results above 1.00% W can support the view that Warby hosts multiple mineralised veins worthy of follow-up work.
The outlier in the set, sample 106163, returned less than 0.20% W but still carried 234 ppm tin and 0.08 ppm gold, with malachite noted in the description. That combination may indicate a distinct part of the mineral system rather than an absence of mineralisation.
A Polymetallic Signature Is Emerging at Warby
Beyond tungsten, the Phase 2 results continued to show associated gold and tin. The clearest example is sample 106161, which returned 2.22 ppm gold, 0.21% tin, and 1.31% tungsten from a brecciated quartz vein.
Furthermore, this sample was collected approximately 50 metres west of a Phase 1 rock chip sample, 105491, which returned 1.40 g/t gold, 0.33% tin, and 0.88% tungsten. The recurrence of this metal association across separate phases may improve confidence that gold, tin, and tungsten are related parts of the same broader mineralising system.
That matters because polymetallic systems can be geologically significant. They may indicate multiple mineralising events or fluid pulses, which in some cases can widen the search area and help geologists identify where the highest-grade zones may be concentrated.
Why the Metal Association Matters
In the report, Lightning interpreted the elevated tin values as potentially linked to stannite, a copper-iron-tin sulphide mineral. The company also noted that later reactivation of regional structures may have brecciated earlier quartz veins and introduced a second phase of wolframite and copper sulphide mineralisation.
For non-specialist readers, this means the project may not be defined by a single, simple vein event. Instead, Warby appears to show signs of a mineral system that formed in stages — an important feature when assessing exploration potential.
Understanding Wolframite and Tungsten Mineralisation
Tungsten is the primary commodity at Warby, and the key ore mineral identified in the announcement is wolframite, specifically a ferberite-rich variety. Wolframite is one of the main minerals mined globally for tungsten production.
At Warby, wolframite was observed as coarse, needle-like crystals up to 3 centimetres long, and also as finer grains spread through quartz veins. Visible coarse wolframite in rock chip material is a useful indicator during early exploration because it confirms the presence of the target mineral rather than only a geochemical signal in laboratory assays.

Why Does Tungsten Attract Market Attention?
Tungsten is used in cutting tools, drill bits, aerospace alloys, armour-piercing applications, and advanced manufacturing. Its industrial value comes from two main physical properties: exceptional hardness and a very high melting point.
In addition, the company noted tighter global tungsten supply conditions following export restrictions from China, which remains the dominant supplier of processed tungsten products. For investors, this is relevant at a commodity level because it can increase attention on exploration projects in jurisdictions such as Australia. It does not, however, imply any project-specific support or assured commercial outcome for Warby.
Why Warby's Geology Is Relevant
The Warby Project sits within the Meso-Proterozoic Lyndbrook Complex, which comprises gneiss, schist, and coarse granite affected by multiple deformation events. In simpler terms, it is an older, structurally complex geological setting where cracks and faults may have provided pathways for mineral-rich fluids.
According to the announcement, NNW-oriented faulting linked to movement along the Lynd Mylonite Zone helped accommodate intrusive granite dykes and associated wolframite mineralisation. Later movement along those same structures appears to have broken earlier quartz veins and introduced additional mineralisation.
This structural history is relevant because it helps explain why the company is seeing multiple veins rather than a single isolated occurrence. The Phase 2 program extended known veins to the southeast, while historical regional drainage anomalies east of the current workings suggest there may be additional tungsten-bearing systems elsewhere on the tenure.
The project is located approximately 25 kilometres north of Mount Surprise and in regional proximity to the Mt Carbine tungsten mine. That geographic comparison provides geological context only and should not be read as an indication that Warby has comparable scale, grade, or development potential at this stage.
Phase 2 Program Details and What Comes Next
The Phase 2 field program, completed in July 2026, included more than just rock chip sampling. According to the report, Lightning also collected:
- 90 soil samples
- 17 panned concentrate samples from active drainage areas covering 4.32 square kilometres
- 21 reference samples of non-mineralised rocks from dump material
The company expects soil and drainage assay results by the end of August 2026. Those datasets are intended to be integrated with geological mapping, structural interpretation, and historical exploration information to guide Phase 3.
Planned Phase 3 Work
| Activity | Status / Timing |
|---|---|
| Soil and drainage assays | Expected by end of August 2026 |
| Geological and geochemical interpretation | After all assays are received |
| Integration with structural mapping and historical data | Planned |
| Ranking of tungsten anomalies | Planned |
| Trenching to expose veins and confirm strike lengths | Planned for Phase 3 |
| LiDAR survey to identify additional veins | Planned for Phase 3 |
| Future drill target identification | Following interpretation and fieldwork |
For investors, the next dataset is likely to be important because soil and drainage sampling can help define broader geochemical patterns beyond the small number of highly selective rock chips. If those results show coherent tungsten anomalies around the current workings or further east, they may improve confidence in the scale of the target area.

What Investors Should Take From This Update
This ASX update does not define a resource, and the company has cautioned that results come from historical dump material rather than measured in-situ veins. The current sampling density is also insufficient to establish geological or grade continuity.
Even with those limitations, several points stand out from the announcement:
- High-grade tungsten has now been reported in two phases of work
- Five of six Phase 2 samples returned more than 1.00% W
- Known veins were extended to the southeast
- Gold and tin continue to appear alongside tungsten
- Historical drainage anomalies east of workings may point to a larger prospective area
- No evidence of modern systematic tungsten exploration has been identified over the current target area
That combination gives Lightning a clearer basis for Phase 3 planning. The key question from here is whether broader sampling and, subsequently, trenching and drilling can demonstrate continuity, scale, and geometry beyond the highly selective dump samples.
Lightning Minerals' flagship asset remains the Mt Turner Gold Project in northern Queensland, with additional gold and copper assets in New South Wales and Western Australia. Within that broader portfolio, Warby is emerging as an early-stage tungsten opportunity that is starting to build a more detailed geological picture.
According to the Phase 2 update, Warby continues to return high-grade tungsten in selective surface samples, while also showing a recurring gold-tin-tungsten association. The immediate catalyst is the expected arrival of 90 soil assays and 17 drainage assays by the end of August 2026, which should help determine where Lightning focuses trenching, LiDAR work, and future drill target selection.
