Kairos Minerals has confirmed a significant extension to its Mt York gold mineralisation, with new drilling results revealing strong near-surface and deeper gold zones over an additional 1.2km strike. An updated resource estimate is expected in the first half of 2026.
- Main Hill Extension adds 1,200m to Mt York gold strike length
- High-grade intercepts include 16m at 2.60 g/t Au and 9m at 3.92 g/t Au
- Gold mineralisation now spans over 4.2km strike
- Updated Mineral Resource Estimate incorporating 27,000m drilling planned for H1 2026
- Kairos holds $25M cash to fund further drilling and prefeasibility studies
Significant Extension at Mt York
Kairos Minerals Ltd (ASX – KAI) has announced promising drilling results from its Main Hill Extension prospect, part of the 1.4 million ounce Mt York Gold Project in Western Australia's Pilbara region. The recent campaign, which included 46 drill holes with results from 35 reported, has confirmed an extension of gold mineralisation over an additional 1,200 metres of strike length. This brings the total known mineralised strike at Mt York to over 4.2 kilometres.
Encouraging Drill Intercepts
The drilling targeted shallow zones of mineralisation within banded iron formation (BIF) units, a key host rock for gold at Mt York. Notable intercepts include 16 metres at 2.60 grams per tonne (g/t) gold from 143 metres depth, including a high-grade 2 metres at 12.45 g/t, and 9 metres at 3.92 g/t from 97 metres. These results, obtained from reconnaissance drilling spaced approximately 100 metres apart, suggest both near-surface and deeper mineralised zones remain open for further expansion.
Resource Growth and Development Outlook
Kairos plans to incorporate these new results, alongside approximately 27,000 metres of drilling completed across Mt York in 2025, into an updated Mineral Resource Estimate (MRE) scheduled for release in the first half of 2026. The company is optimistic that this update will not only increase the resource size but also improve confidence levels, underpinning ongoing prefeasibility studies. With a strong cash position of $25 million and a newly granted mining lease, Kairos is well positioned to advance further drilling and development work.
Geological Insights and Exploration Potential
The Main Hill Extension drilling has revealed multiple mineralised BIF units, some previously unrecognised, indicating a complex structural setting with potential for thicker and higher-grade zones. Structural features such as folds and fault offsets appear to control mineralisation distribution, offering new targets for future exploration. The continuity of mineralisation from Main Hill to the northwest aligns with the broader Main Trend geology, reinforcing the prospectivity of the area.
Next Steps for Kairos
Remaining assay results from the current drilling program are awaited, with plans underway for infill and deeper drilling to enhance resource definition. Additional diamond drilling will also support metallurgical and geotechnical studies critical for advancing the Mt York prefeasibility study. Kairos continues to explore its extensive Pilbara tenement holdings, aiming to unlock further value from this emerging gold district.
Bottom Line?
Kairos’ expanding resource base at Mt York sets the stage for a pivotal resource update and development decisions in 2026.
Questions in the middle?
- How much will the updated Mineral Resource Estimate increase the total gold ounces at Mt York?
- What impact will the new high-grade zones have on the project’s economic viability?
- How will Kairos prioritise drilling targets to maximise resource growth and confidence?
