Lunnon Metals (ASX:LM8) sharpens focus on Southern Foster Gold Belt with new gold insights

Lunnon Metals (ASX:LM8) has made meaningful strides in its Foster Gold Belt exploration campaign, delivering promising surface and drill results at key prospects that may reshape the geological outlook of the southern corridor.

In a Q&A with Managing Director Edmund Ainscough, the company laid out a technically informed and strategically balanced view of where things stand and what comes next.

At the centre of this momentum is the Halloween prospect, where high grade surface sampling has yielded grades up to 26.81 grams per tonne gold an unusually strong outcome for grab samples.

“The recent grab samples at Halloween are an exciting development that enhance our understanding of gold distribution within the Foster Gold Belt.”

The standout grades, which also included 19.32 and 17.16 grams per tonne, suggest the presence of a narrow paleochannel hosting transported alluvial gold.

Notably, these results correlate with historical high-grade aircore intercepts that were once viewed as isolated.

Sitting just 500 metres south of the Guiding Star prospect, Halloween is now interpreted as a potential southern extension of mineralisation from Guiding Star, where gold may have been shed into a structural channel.

This emerging theory introduces a compelling new feature into Lunnon’s geological model and may explain why past campaigns overlooked the target.

Lunnon Metals is moving quickly to design follow up drilling at Halloween with a focus on tracing this newly defined paleochannel.

The Guiding Star prospect itself has also delivered fresh insight.

While gold grades such as 21 metres at 0.56 grams per tonne and 16 metres at 0.53 grams per tonne are considered moderate in isolation, the real value lies in how these results tie into a more refined understanding of the deposit’s structural setting.

Through the use of downhole optical televiewer surveys, Lunnon now interprets at least two distinct mineralised orientations one gently dipping east and another steeply trending north-south.

“Our interpretation now suggests that these previous intercepts, including 14 metres at 0.80 grams per tonne and 11 metres at 1.14 grams per tonne, may sit on steeper structures that have not yet been adequately tested.”

This dual geometry explains inconsistencies in historical drilling and gives the company a clearer vector for future targeting.

The shallow depth of mineralisation and proximity to infrastructure further reinforce the strategic importance of the prospect.

When viewed together, Halloween and Guiding Star represent key pieces in Lunnon’s broader Foster Gold Belt strategy.

Both are located within a structural corridor that aligns with the northern extension of the Argo-Apollo trend, known for its million ounce gold endowment on adjacent leases held by Gold Fields.

“Our recent work demonstrates that this corridor on Lunnon’s ground hosts multiple structural orientations and lithologies capable of focusing gold mineralisation.”

The combination of surface sampling, RC drilling and structural analysis has led to a re-rating of this southern corridor’s prospectivity.

In addition to Halloween and Guiding Star, Lunnon is integrating these findings into its evaluation of new targets such as Hustler and Koombana.

The aim is to build a pipeline of exploration-ready assets, all within reach of future development pathways.

Not all outcomes were positive in this campaign, with Violet and Killarney North downgraded following underwhelming drill results.

Yet, Ainscough maintains that the learnings were valuable.

At Violet, drilling intersected quartz veining, but the host dolerite was poorly developed.

At Killarney North, while the targeted doleritic units were intersected, the structural complexity needed to host mineralisation was not observed.

“The value in these programs lies in what we have learned. The data collected allows us to refine our lithostructural models, particularly through the use of multi-element geochemistry and geophysical interpretation.”

Such refinements are being applied to the design of the EIS funded Defiance West hole, which will provide broader geochemical and structural insight across the belt.

In exploration, understanding where not to drill can help reduce risk and sharpen the focus for future campaigns.

Looking ahead, the company plans to launch focused follow-up programs at both Halloween and Guiding Star to test the extent and continuity of mineralisation.

The ultimate objective is to define new mineral resources that can complement the company’s existing Lady Herial resource, which currently stands at 29,000 ounces at 1.6 grams per tonne.

“This dual approach of advancing and permitting known resources while continuing to explore new targets is central to our strategy of building a pipeline of gold assets within the Foster Gold Belt.”

The broader vision is to establish a cluster of deposits that can be developed in parallel, potentially leveraging synergies with processing infrastructure owned by Lunnon’s major shareholder, Gold Fields Ltd.

With strong technical foundations and a clear strategic roadmap, Lunnon’s latest round of exploration suggests the southern Foster Gold Belt may yet have more to reveal.
