Mt York Gold Project

Kairos’s flagship, 100%-owned 2.1Moz Mt York Gold Project is 100km south of Port Hedland in WA’s Pilbara. The project is supported by excellent infrastructure.

The Mt York gold project is a continuous zone of gold mineralisation hosted within a banded iron formation (BIF), with mineralisation confirmed over 4.2km of strike length.

The 2025 drilling underpinning the MRE update focussed on extending mineralisation at depth at Breccia Hill and Main Hill, testing along strike to the northwest onto the Main Hill Extension beyond the limits of the existing resource, and to infill and increase the confidence level of thick zones of mineralisation at Main Hill.  All of these aims were achieved in 2025, with mineralisation extended in all directions with the deposit remaining open at depth and along strike.

The April 2026 update MRE of 61.7 Mt at 1.05g/t Au for 2.08Moz represented a 43% increase in tonnes and a 5% increase in grade for an overall 50% increase in contained gold from 1.38Moz in the 2023 Resource.  The updated Mt York MRE was reported within an optimised pit shell based on a A$5500/oz gold price and is reported above a 0.40 g/t Au cut-off grade.

A fully-funded pre-feasibility study (PFS) for Mt York is underway in 2026, based on the April 2026 Mineral Resource Estimate, building on the 2024 Scoping Study.

Drilling in 2026 also aims to test a number of satellite targets to Mt York including Carlindi (acquired from Trek Metals in January 2026), Gilt Dragon, Zakanaka, Lucky 13 and Hazelby.

Carlindi: Highest priority of these targets with solid drill hits in historic drilling. Kairos plans to follow this up with drilling in CY2026.

Gilt Dragon: A gold prospect 3km southeast of Main Trend with historic early-stage drill results, including 10m @ 2.04g/t Au from 4m, and a large gold footprint identified in surface sampling.

Zakanaka: A historic open pit mining centre 2km north of Main Trend with mineralisation remaining open along strike and at depth.
