Iceni’s Guyer Discovery Raises Questions on Scale and Next Exploration Steps

Iceni Gold’s Expanding Footprint at Guyer

Iceni Gold Limited (ASX – ICL) has announced the final results from a substantial reverse circulation drilling campaign at its Guyer Trend, part of the flagship 14 Mile Well Gold Project in Western Australia. The program, comprising 59 holes totaling 10,842 metres, has confirmed that Guyer hosts a large and evolving gold system with two distinct mineralisation styles.

Located between the historic gold towns of Leonora and Laverton, the 14 Mile Well Project is strategically positioned within a prolific gold district. The Guyer Trend, a priority target within this project, lies along the eastern margin of the Danjo Granite, a major geological feature that appears to control gold mineralisation.

Two Styles of Gold Mineralisation

The drilling results reveal two contrasting gold mineralisation styles. The first is granite-hosted mineralisation occurring along flat-lying shears within the Danjo Granite, characterised by a leached regolith profile with broadly dispersed gold at the saprock contact. The second, and perhaps more exciting, is basalt-hosted mineralisation associated with steeply dipping shears within basalt units. This style exhibits a stripped, poorly developed regolith with a more restricted gold footprint but has returned strong high-grade intercepts, including 7 metres at 1.48 grams per tonne gold and 3 metres at 3.26 grams per tonne gold.

These findings suggest that the Guyer system is more extensive and complex than previously understood, with the basalt-hosted trend remaining open and largely untested. This opens new avenues for exploration beneath transported cover, an area that had been underexplored due to prior focus on granite-hosted mineralisation.

Structural Insights from Deep Drilling

A single diamond drill hole, the first deep test across the granite-mafic contact, provided valuable geological insights. It confirmed a diffuse contact zone comprising intermingled granodiorite, dolerite, and porphyritic intrusions, supporting the interpretation of this contact as a major structural boundary influencing gold mineralisation. Although no significant economic mineralisation was encountered in this hole, the structural data will guide future targeting and drilling strategies.

Strategic Partnership and Next Steps

This drilling program fulfills the initial $5 million minimum exploration commitment under a $35 million Farm-In and Joint Venture Agreement with Gold Fields Limited, which recently acquired Gold Road Resources Limited, Iceni’s partner in the project. The partnership with a major gold producer like Gold Fields underscores the potential of the Guyer Trend and the broader 14 Mile Well Project.

Iceni is now preparing for follow-up drilling to expand on the promising results, particularly targeting the basalt-hosted mineralisation and high-grade intercepts such as those in hole GUYRC0083. Multi-element assay results are pending and expected to provide further insights into the mineral system. The next phase of exploration will be formalised at the upcoming Farm-In Exploration Committee meeting.

With a large contiguous tenement package and multiple high-priority targets, Iceni Gold is positioning itself as a significant player in the Leonora-Laverton gold district. The evolving understanding of the Guyer system’s scale and complexity could unlock substantial value for the company and its shareholders.
