Resource Growth Hinges on Pending ‘Monster Zone’ Results at Mt York

Kairos Minerals reports significant wide and high-grade gold intercepts from recent drilling at Mt York’s Main Hill, reinforcing potential for resource growth ahead of a key update.

  • Wide gold mineralisation zones up to 100m thick confirmed at Main Hill
  • High-grade intercepts include 84m at 1.10 g/t Au and 1.65m at 14.98 g/t Au
  • Additional drilling completed on ‘Monster Zone’ with results pending
  • Stage 1 drilling program ahead of schedule and on budget
  • Updated mineral resource estimate expected in second half of 2025

Strong Drilling Results Validate New Structural Model

Kairos Minerals Ltd (ASX – KAI) has delivered encouraging results from its ongoing drilling campaign at the Mt York Gold Project in Western Australia’s Pilbara region. The latest assays from nine diamond drill holes, predominantly at the Main Hill prospect, reveal extensive zones of gold mineralisation, some exceeding 100 metres in true width. These findings support the company’s revised geological model, which anticipates broad, high-grade gold zones within the banded iron formation (BIF) that dominates the Main Hill area.

Among the standout results is drill hole 25MYDD041, which intercepted 144 metres grading 0.90 grams per tonne gold from just 8 metres depth, including an 84-metre section at 1.10 g/t Au. Notably, within this interval lies a 20-metre stretch averaging 2.08 g/t Au, highlighting the presence of higher-grade shoots within the broader mineralised envelope. Another hole, 25MYDD043, returned a narrower but very high-grade intercept of 1.65 metres at 14.98 g/t Au, underscoring the prospect’s potential for rich ore zones.

‘Monster Zone’ Drilling Advances Resource Expansion

Building on a recent discovery dubbed the ‘Monster Zone’; a wide mineralised shoot that previously yielded 53 metres at 1.45 g/t Au; Kairos has completed five additional diamond holes targeting this exciting area. While assay results from these holes are still awaited, the company anticipates they will further enhance the resource base. The Stage 1 drilling program, designed to expand and upgrade the existing 1.4 million ounce resource, is progressing ahead of schedule and within budget, with 59 of the planned 80 holes completed to date.

Managing Director Dr Peter Turner expressed optimism about the results, noting that the consistent wide zones of mineralisation and the identification of multiple higher-grade shoots could materially increase the project’s gold inventory. He also highlighted the favourable mining conditions at Main Hill, where mineralisation outcrops at surface, potentially enabling low strip ratios and cost-effective extraction.

Next Steps – Resource Update and Development Planning

Looking ahead, Kairos plans to finalise the Stage 1 drilling program and incorporate the new data into an updated Mineral Resource Estimate (MRE) expected in the second half of 2025. Concurrently, the company is advancing negotiations for mineral rights agreements with PLS and mining agreements with the Nyamal Aboriginal Corporation, critical steps for unlocking access to additional tenements and progressing towards development.

Further metallurgical and geotechnical studies are also planned, leveraging fresh core samples from the drilling campaign to refine processing and mine design parameters. These efforts align with Kairos’s broader strategy to enhance project economics and prepare for a potential scoping study update.

While results from the ‘Monster Zone’ drilling remain pending, the current data solidifies Mt York’s status as a significant gold exploration and development opportunity in the Pilbara, with the potential to grow beyond its current 1.4 million ounce resource base.

Bottom Line?

Kairos’s latest drilling success at Mt York sets the stage for a resource upgrade that could reshape the project’s development trajectory.

Questions in the middle?

  • How will the pending ‘Monster Zone’ assay results impact the overall resource estimate?
  • What are the timelines and terms expected for finalising mineral rights and mining agreements with PLS and Nyamal Aboriginal Corporation?
  • How might metallurgical test outcomes influence future mine planning and processing strategies?
