Drilling Results Confirm Yarrol as a Continuous and Scalable Gold System

Mila Resources Plc (LSE: MILA), the post-discovery gold exploration accelerator, is pleased to report the final assay results from its Diamond Drilling ('DD') programme in Q4 2025 at the Yarrol Gold Project, Queensland ('Yarrol' or the 'Project').  These results include targeted follow-up sampling and multi-element assays, which have materially enhanced the Company's understanding of the mineralised system.

The Company has also now completed its Q1 2026 reverse circulation ('RC') drilling programme focused on infill, strike extension and early-stage volume definition on order to advance towards resource delineation.  This latest 1,600m drill programme brings the Company's total drilling to 4,921m across its Queensland portfolio since acquiring the projects.

Overview

·      Multiple drillholes intersected broad mineralised zones with internal high-grade shoots

·      Best continuous intercepts including:

o  14 m @ 1.10 g/t gold ('Au') from 183 m in MYADD0205

§ Including 1.0 m @ 7.51 g/t Au from 183 and 1 m @ 6.4 g/t from 187 m. (MYADD0205)

o  5.0 m @ 1.4 g/t Au from 143 m in MYADD0206

§ Including 1.0 m @ 6.83 g/t Au from 143 m

o  3.0 m @ 3.4 g/t Au from 51.0 m in MYADD0208

§ Including 0.45 m @ 10.05 g/t Au from 52.25 m

o  5.0 m @ 1.07 g/t Au from 195.0 m in MYADD0209

§ Including 1 m @ 5.05 g/t from 195 m.  

·      Multiple stacked mineralised intervals identified in MYADD0205 and MYADD0206

·      Pathfinder geochemistry, arsenic and tellurium ('As' and 'Te') defines a coherent mineralised system and provides clear vectors to high-grade zones

·      Mineralisation confirmed across all holes, confirming a laterally and vertically continuous mineralised system, with broad envelopes hosting discrete higher-grade shoots.

·      Interpretation of cross-sections demonstrates that mineralisation can now be traced from surface through to depth, providing confidence in the overall geometry and continuity of the system.

·      This work represents a clear progression from initial discovery to a defined and coherent gold system, with continuity, geometry and vectors to higher-grade mineralisation now well established.

·      This continuity enables the Company to systematically extend mineralisation along strike whilst building coherent volume, which will be progressively refined with the objective of defining a Mineral Resource Estimate.

Next Steps

·      Target higher-grade shoots along strike and at depth

·      Prioritise zones with coincident Au-Te-As signatures

·      Advance drilling to define geometry, continuity and scale of mineralisation

·    Continue building dataset towards resource definition

Mark Stephenson, Executive Chairman, Commented:

"The Q4 2025 diamond drilling results at Yarrol demonstrate a continuous and growing gold system, with broad mineralised zones and discrete higher-grade shoots confirming the robustness of our geological model.

"Integration of multi-element geochemistry is giving us clear vectors to the high-grade cores, while continuity from surface to depth allows us to define a coherent volume of mineralisation for resource planning.

"The Q1 2026 RC campaign is now complete, and we await results that we believe will expand the footprint of the system, highlighting that Yarrol remains very much open to growth.

"Yarrol is a connected, evolving system and these results provide a solid platform for the next phase of drilling.  Work at Mt Steadman and Monal also continues in parallel as we look to develop a portfolio of high value development assets in Queensland."

Further Information on the Q4 2025 Diamond Drilling Results

The Company's understanding of the mineralised system has been significantly enhanced by the follow-up sampling after the initial results, together with multi-element assay analysis. A coherent geochemical signature has been identified across multiple drillholes, with gold mineralisation closely associated with arsenic and tellurium.             

In addition to several high-grade gold intercepts exceeding 5 g/t Au, the data defines a broader halo of pathfinder elements extending beyond previously interpreted mineralisation. Numerous intervals with modest gold grades exhibit elevated pathfinder geochemistry, indicating proximity to higher-grade zones and supporting the interpretation of a larger, more continuous and well-developed mineralised system.         

These patterns are consistent with structurally controlled, sulphide-associated gold mineralisation, where higher-grade shoots are developed within wider mineralised envelopes. The presence of arsenic and tellurium with the highest-grade gold provides a clear and reliable vector towards the higher-grade core of the system and will be used to guide future drilling.

The drilling programme has successfully delivered on its objectives, confirming both the continuity and scale of the mineralised system while identifying discrete higher-grade shoots. Importantly, gold mineralisation was intersected in all holes, demonstrating a robust and continuous system. While higher-grade intercepts validate the presence of well-developed shoots, broader and lower-grade intervals define the extent of the mineralised envelope and provide important constraints on the geometry and controls of mineralisation.

Geological Interpretation

The drilling defines a coherent mineralised system with clear internal zonation:

Collectively, the results demonstrate a well-developed mineralised system with clear internal zonation, where higher-grade shoots are hosted within broader mineralised envelopes, and where both high-grade and lower-grade intersections contribute to defining the geometry and continuity of the system.

·      MYADD0205 and MYADD0206 intersect broad, consistently mineralised zones and are interpreted to lie close to the core of the system, with multiple stacked intervals and higher-grade shoots.

·      MYADD0208 and MYADD0209 intersect narrower but higher-grade mineralisation, interpreted as discrete shoots along strike and at depth.

·      MYADD0207 and MYADD0210 return lower-grade mineralisation and are interpreted to lie on the margins of the system.

Additional Mineralised Intervals

Drilling has identified multiple mineralised zones within individual holes, particularly in MYADD0205 and MYADD0206, where broad mineralised bands host higher-grade internal zones. Note, zones in table do not allow internal dilution in intercepts

Significant Drill Intercepts (Au ≥0.30 g/t, no internal dilution).

Completion of Q1 2026 RC Campaign

Following recent heavy rains in the region that delayed completion, the team is pleased to report the completion of a successful campaign building on the results of the DD programme. This programme targeted a combination of infill, strike extensions, and satellite prospects from surface to approximately 200 metres depth and is designed to advance towards resource definition.

As Yarrol advances from discovery into resource definition, results will be released in context, enabling the market to recognise the scale of the opportunity as it is progressively defined.
