Kairos Minerals Strengthens Gold Resource Potential at Mt York with Main Hill Drilling Results

Kairos Minerals (ASX: KAI) has confirmed further wide zones of gold mineralisation from drilling at its Mt York project in Western Australia’s Pilbara region.

The latest nine-hole program delivered standout results including 84 metres at 1.10 grams per tonne gold, strengthening the company’s confidence in resource growth.

Management said the results show Main Hill emerging as a kilometre-long, 100m-wide mineralised system that could meaningfully expand the project’s scale.

Results Reinforce Resource Potential

Drilling at Main Hill returned an impressive 144m at 0.90 g/t gold from near surface, which included higher-grade zones of 20m at 2.08 g/t and 6m at 3.03 g/t.

Importantly, Main Hill continues to show continuity along strike and at depth, suggesting the system remains open.

Managing director Dr Peter Turner described the results as validation of the company’s structural model, emphasising that higher-grade shoots within the broader envelope add another layer of value because they provide flexibility in mine scheduling and could enhance early project economics.

The presence of both bulk-tonnage and higher-grade components gives Kairos optionality in designing future development pathways.

‘Monster Zone’ Extension Drilling

Attention is also turning to the “Monster Zone” area of mineralisation Kairos discovered in August with a 53m intercept grading 1.45 g/t gold from 212m.

The company has now drilled five additional diamond holes across 400m of strike to test whether this zone extends further southeast, which would open another large target that could rival Main Hill in importance.

The Monster Zone is significant because it sits within the same structural corridor, but its geometry and grade profile may differ from Main Hill.

Either way, management has made it clear that results from Monster will feed directly into the next resource update, and has promised regular updates once routine quality-assurance, quality-control checks are completed.

Strategic Growth Plan

Stage 1 drilling at Mt York has already delivered more than 15,500m from 59 holes, with Kairos expecting to complete the full 80-hole, 18,000m program this quarter, setting up the next mineral resource estimate in the second half of 2025.

Stage 2 drilling, which the company has planned for late 2025 or early 2026, will then focus on upgrading Inferred resources to the Indicated category, which is crucial for economic studies.

Kairos is looking beyond drilling to ensure the project’s development pathway remains on track, finalising a mineral rights agreement with Pilbara Minerals covering 367 sq km of prospective ground including extensions of the Main Hill trend.

Kairos plans to commence prefeasibility study work, including metallurgical test programs using core from fresh, transitional and oxide zones, to refine processing routes, confirm recoveries and support mine scheduling scenarios.

The company is also negotiating with the Nyamal Aboriginal Corporation to secure a mining agreement, which will be critical for project approvals and long-term certainty.
