Litchfield Minerals Starts Drilling Up to 11 Holes at Flagship Copper-Zinc Project
Key Takeaways
- Litchfield Minerals began drilling at its flagship Oonagalabi Copper-Zinc Project on 12 October 2026, delivering on the October start promised in its 24 September announcement.
- The programme targets approximately 7 to 11 drill holes, with the final number depending on drilling productivity, ground conditions and campaign time.
- Drilling aims to test priority targets, evaluate the continuity of copper-zinc mineralisation and probe extensions to known mineralisation.
- No assay results have been released and no timing has been disclosed, so this is a testing phase rather than a discovery.
- Drill priorities may shift as geological observations come in, with further updates promised as material results become available.
Drilling commences at Oonagalabi copper-zinc project
Litchfield Minerals (ASX: LMS) has commenced drilling at its flagship Oonagalabi Copper-Zinc Project in the Harts Range region of the Northern Territory. The announcement was dated 12 October 2026.
The programme is expected to comprise approximately 7 to 11 drill holes. The final number depends on drilling productivity, ground conditions and the time available during the current campaign.
The start follows the company’s earlier announcement of 24 September 2026, titled “LMS Secures Rig to Start October Drilling at Oonagalabi”. The company has now moved from planning to execution, which gives investors a point to watch for news flow as the campaign progresses.
Matthew Pustahya, Managing Director
“We are targeting between seven and eleven holes during this campaign, depending on drilling conditions and available time, and will remain flexible in how we allocate drilling metres to maximise the geological information obtained.”

What the programme aims to test
Drilling will focus on priority targets identified through the company’s ongoing geological interpretation and exploration activities. The stated objectives are:
- Systematically test priority geological targets.
- Evaluate the extent and continuity of copper-zinc mineralisation.
- Test opportunities for extensions to known copper-zinc mineralisation.
- Refine the geological model and identify opportunities for follow-up drilling.
The company said it will continue to assess geological observations throughout the campaign, allowing drill priorities to be refined as new information becomes available. In practice, the plan is not fixed, and the targets may shift as the rigs turn.
| Item | Detail | Investor relevance |
|---|---|---|
| Planned holes | 7 to 11 (approximate) | The final number depends on productivity, ground conditions and campaign time |
| Location | Oonagalabi Copper-Zinc Project, Harts Range region, Northern Territory | The company’s flagship project |
| Purpose | Test priority targets and opportunities for extensions | Results are intended to refine the geological model |
No assay results have been released. Nothing in the announcement points to a discovery, so the drilling is best read as testing, not confirmation.
Why drilling matters in copper exploration
Drilling is how explorers physically sample rock beneath the surface. It tests whether the geological model, the company’s working picture of what lies underground, holds up against real samples.
Two terms matter here. Continuity asks whether mineralisation links up between drill holes, while extensions ask whether it continues beyond the areas already known.
Those answers shape what comes next, including whether a company chooses to plan follow-up drilling. That is why the company describes its results as helping to refine the geological model and identify follow-up opportunities.

What investors can watch next
The company said it will provide further updates “as material results become available”. No timing for assay results has been disclosed.
Watch points include:
- Progress on hole count within the 7 to 11 range.
- Any refinement of drill priorities as geological observations are assessed.
- The release of results and any follow-up drilling plans.
Litchfield describes itself as an Australian mineral exploration company advancing a belt-scale Cu-Ni-PGE thesis across the Harts Range / Oonagalabi corridor at the Aileron-Irindina boundary in the Northern Territory.
For readers wanting to understand the belt-scale thesis behind the company’s strategy, our deep-dive into the Harts Range copper-nickel district explains how the corridor is being reframed and what that means for exploration targeting beyond Oonagalabi.
