Kairos Minerals has revealed a significant new gold discovery at its Mt York project in Western Australia, highlighted by a 53m intercept grading 1.45 g/t Au near Main Hill. This breakthrough could materially expand the project’s 1.4 million ounce resource base.
- 53m @ 1.45 g/t Au intercept near Main Hill in previously undrilled ‘Monster’ zone
- Stage 1 drilling ahead of schedule with 52 holes completed out of 80 planned
- New structural fold flexure identified, potentially extending mineralisation along 3km Main Trend
- Positive impact expected on updated resource estimate due in second half of 2025
- Ongoing negotiations for mineral rights and mining agreements to unlock further exploration
A New Chapter at Mt York
Kairos Minerals Ltd (ASX – KAI) has announced a breakthrough in its ongoing exploration at the Mt York Gold Project in Western Australia’s Pilbara region. The company’s latest drilling results have uncovered a substantial new zone of gold mineralisation near the Main Hill prospect, dubbed the ‘Monster’ zone by on-site geologists. The standout intercept, 53 metres grading 1.45 grams per tonne gold from 212 metres depth, including a higher-grade 10-metre section at 2.95 g/t Au, marks a significant extension to the known mineralisation footprint.
Implications of the ‘Monster’ Zone Discovery
This discovery is particularly notable because it lies in an area that had not been previously drilled, suggesting untapped potential within the 3-kilometre-long Main Trend. Geological interpretation points to a new structural fold flexure or closure within the banded iron formation (BIF) host rocks, a feature that has historically been associated with thick, high-grade gold mineralisation at Mt York. If further drilling confirms this structural model, it could significantly increase the project’s resource size, especially around Main Hill and its extensions.
Drilling Progress and Resource Expansion
The Stage 1 drilling campaign is progressing well, with 52 of the planned 80 diamond drill holes completed, totaling over 13,500 metres, both ahead of schedule and within budget. Results from 19 holes have been received, revealing multiple encouraging intercepts including 62m at 0.78 g/t Au and 22m at 1.30 g/t Au in addition to the ‘Monster’ zone. These results are expected to feed into an updated Mineral Resource Estimate (MRE) slated for release in the second half of 2025, which could materially enhance the current 1.4 million ounce gold resource.
Strategic Partnerships and Next Steps
Beyond exploration, Kairos is actively working to secure mineral rights agreements with Pilbara Minerals Limited (PLS) to access the Main Hill Extension prospect and other adjacent tenements. Concurrently, negotiations with the Nyamal Aboriginal Corporation are underway to establish a mining agreement, a critical step for advancing the project towards development. The company also plans to commence a Pre-Feasibility Study (PFS) incorporating advanced metallurgical testing once fresh core samples are available.
Looking Ahead
With drilling continuing through August and September, Kairos is poised to unlock further insights into the Mt York deposit’s potential. The combination of a new structural discovery, robust drill results, and strategic agreements positions Mt York as a compelling candidate to become one of the Pilbara’s largest undeveloped gold resources. Investors and industry watchers will be keenly awaiting the updated resource estimate and subsequent development milestones.
Bottom Line?
Kairos’ ‘Monster’ discovery at Mt York could redefine the project’s scale, but further drilling and agreements remain pivotal.
Questions in the middle?
- How extensive is the ‘Monster’ zone along strike and at depth beyond current drilling?
- What impact will the new structural interpretation have on mining and processing plans?
- When will the mineral rights and mining agreements be finalized to unlock full project potential?
