Lightning Minerals Drills Mt Turner Gold Corridor, Targeting Maiden Resource in 2027
Key Takeaways
- Lightning Minerals has started Phase 2 drilling at its wholly owned Mt Turner Gold Project: four diamond holes for about 650 metres, running through October.
- The program targets a 950 m section of the 14 km Drummer Fault corridor, which management says has large untested sections.
- The 2025 campaign intersected gold with sulphides beneath historical shallow oxide open-pits and showed mineralisation remains open along strike and at depth.
- A maiden gold Mineral Resource Estimate is targeted for CY 2027, but resource definition drilling has not yet started and the target is not a guarantee.
- No assay timing or results were disclosed, so the next real catalyst is the first assay data and the Phase 3 program design.
Phase 2 drilling underway at Mt Turner
Drilling has started at a gold corridor that management says has large untested sections. Lightning Minerals (ASX: L1M) has commenced Phase 2 drilling at its wholly owned Mt Turner Gold Project in North Queensland, as announced on 6 October 2026.
The initial program covers four diamond drill holes for approximately 650 metres. It will test extensions to known high grade mineralisation along strike (sideways along the structure) and at depth, using a truck-mounted diamond rig.
The announcement describes the target as a 950 m section of the 14km Drummer Fault corridor. A maiden gold Mineral Resource Estimate (MRE) is targeted for CY 2027, though a target is not a guarantee.
For you as an investor, this is the next step in turning a validated geological model into something measurable. Drilling generates the data that any future resource estimate would depend on.
Troy Brice, Managing Director
“Commencement of drilling at Mt Turner is an important milestone as we advance our district-scale gold system toward resource definition.”

Building on the 2025 validation of the Drummer Fault model
What the 2025 campaign confirmed
Phase 2 builds on the 2025 campaign. According to the company, that work:
- Validated its geological model of rhyolite breccia hosted gold-silver mineralisation
- Intersected gold with associated sulphides beneath historical shallow oxide open-pits
- Reduced geological risk across the project
- Showed mineralisation remains open along strike and at depth
Reduced geological risk means the company has more confidence in how the gold system is built. It does not, on its own, say anything about grade or size.
Troy Brice, Managing Director
“…Large sections of the 14-kilometre corridor remain untested and every hole in this program is aimed at advancing Mt Turner toward resource definition…”
Program objectives
The program has been designed to:
- Extend known mineralisation along strike and at depth
- Further evaluate structural controls associated with the Drummer Fault
- Improve geological confidence within priority target areas
- Provide a framework for future resource definition drilling
Drilling is expected to continue throughout October. Geological logging, sampling and assay submission will occur progressively.
How does rhyolite-hosted gold exploration work?
Diamond drilling extracts solid cylinders of rock, known as core, from underground. Geologists can study the core directly to understand rock types, structures and mineralisation.
Framework drilling comes before a resource estimate because an MRE needs enough drill data and geological confidence behind it. Each hole in this program therefore contributes to the broader goal of resource definition.
The Mt Turner Project sits within Queensland’s Etheridge Goldfield and is spatially associated with the Kennedy Igneous Association. The company says it shares similarities with other North Queensland rhyolite hosted gold deposits.
The project is centred on the inner Mt Turner Cu-Mo porphyry system, with peripheral structures hosting gold mineralisation. These include the Drummer Fault and the recently identified Western Zone.

Pathway to a maiden resource and what’s next
Structured roadmap
The company describes Phase 2 as the second step in its structured pathway to a gold based MRE.
| Stage | Status |
|---|---|
| Geological model validation | Completed |
| Framework drilling | Underway |
| Future resource definition drilling | Not yet started |
| Maiden Mineral Resource Estimate | Targeted CY 2027 |
| Development assessment and monetisation studies | Future |
Management believes the project displays key characteristics of an emerging district-scale, multi-element intrusive system. It says multiple mineralised centres and favourable structural controls with substantial strike extents indicate significant potential exploration upside, with the Western Zone and other key target areas also in play.
Upcoming milestones
The announcement lists the following upcoming milestones:
- Completion of the current drilling program
- Assay results and geological interpretation
- Definition of the Phase 3 drilling program
- Follow-up drilling along strike and at depth
The announcement does not disclose assay timing or results. The MRE remains a target only, and the company says it looks forward to providing shareholders with regular updates as results become available.
