Lightning Minerals has enlarged its exploration targets at Mt Turner and Warby, with drilling and assay results now forming the next major catalysts. But the ASX explorer ended September with A$939,000 in cash, equivalent to about one quarter of funding at current outgoings.
- Warby rock chips returned up to 5.5% tungsten, with five of six samples above 1%
- Mt Turner Western Zone outlined two additional gold target areas
- Phase 2 diamond drilling at the Drummer Fault began after quarter end
- A$939,000 cash remained at 30 September against quarterly relevant outgoings of A$912,000
- Further funding or asset transactions are being considered to support exploration
Warby tungsten system expands beyond historical workings
Lightning Minerals Limited (ASX:L1M) has expanded the geological ambition of its Warby project after reconnaissance work pointed to a tungsten system extending well beyond the historical workings. Six rock-chip samples returned up to 5.5% elemental tungsten, with five above 1%, while integrated soil and pan-concentrate results showed anomalies open in several directions along a largely untested 13-kilometre granite contact.
The company is careful to frame those numbers as exploration indicators rather than bulk grades. The rock chips included material from historical artisanal dumps, while pan concentrates can be enriched and do not represent in-situ grades. Even so, the scale of the geochemical response has pushed Warby from reconnaissance sampling towards target generation. The Phase 3 soil program is now processing 162 samples already sent to ALS, with another 100 collected subsequently, and the results are intended to guide a maiden drilling program in 2027. The project had previously entered this stage after its open anomalies were identified and 162 samples were dispatched to the laboratory. Warby Phase 3 soil program
Mt Turner adds gold targets and starts drilling
At flagship Mt Turner, soil sampling in the Western Zone defined two new gold target areas within a five-kilometre corridor alongside the established Drummer Fault. The northern anomaly extends for more than 1,000 metres within a broader 1,400-metre multi-element hydrothermal footprint, while the southern area contains four sub-parallel gold trends and a peak soil result of 330 parts per billion gold. A selective rock chip returned 1.19 grams per tonne gold and 38.80 grams per tonne silver.
Those results remain targets, not mineralised widths or a resource. They nevertheless add to the drilling pipeline, with follow-up soil sampling, rock sampling and trenching planned before initial drill testing. The Western Zone work builds on the company's earlier identification of two gold corridors, including the one-kilometre northern anomaly and southern epithermal-style trends.

Phase 2 diamond drilling at the Drummer Fault began on 5 October, after the reporting period, following a delay attributed primarily to a shortage of drilling personnel in North Queensland. The program is designed to test continuity between historical oxide pits, extensions at depth and the structural controls on mineralisation. Lightning says it is working towards a maiden Mineral Resource Estimate for Mt Turner during 2027, while UNSW petrology has supported an intrusion-related gold model involving rhyolite and dacite intrusions along major structures.
Exploration progress meets a one-quarter cash runway
The operational progress comes with a plainly stated financing constraint. Lightning held A$939,000 at 30 September after recording net operating and investing cash outflows of A$912,000 during the quarter. The completed second tranche of its A$1.85 million placement contributed A$665,000 net of transaction costs to financing cash flow, but the company still reported estimated funding of only one quarter at the current rate of expenditure.
Lightning says it is managing overheads, aligning exploration with available resources and considering further capital through disposals or farm-outs of non-core projects. It also disclosed an arrangement over Lachlan Fold tenements that provides A$100,000 immediately and reduces exploration commitments, after the company had agreed to grant Kincora Copper an option over six licences. Lachlan Fold Belt funding deal That funding is useful, but the filing does not present it as a complete solution to the gap between an active exploration program and the cash balance.
October assays and drilling results become the next test
The immediate evidence will come from Warby Phase 3 assays and the Mt Turner Drummer Fault drilling now under way. Success would still need to be converted into coherent mineralised zones, drill targets and eventually a resource, rather than inferred from isolated surface samples. The company is also evaluating AI-assisted geological interpretation across its Australian portfolio and has divested or surrendered several non-core international interests, but the central question is financial as much as geological: whether the next results arrive quickly enough to support the next funded phase of work.
Bottom Line?
Warby and Mt Turner are producing a fuller target pipeline, but the next assays and drilling results must arrive alongside a credible plan to extend the company’s one-quarter cash runway.
Questions in the middle?
- Will Warby Phase 3 assays convert open surface anomalies into drill targets with sufficient continuity for maiden drilling?
- What will Mt Turner Phase 2 drilling show about the depth and continuity of gold along the Drummer Fault?
- Can asset sales, farm-outs or new funding sustain the planned exploration program without materially changing shareholder exposure?
