Pilbara, WA

Kalamazoo’s West Australian gold portfolio comprises the Ashburton Gold Project (AGP), which the Company acquired from Northern Star Resources Limited (ASX: NST) in 2020 and the Mallina West Gold Project.

Covering 217km², the AGP is located on the southern edge of the Pilbara Craton in Western Australia.  Kalamazoo delivered an enhanced Mineral Resource Estimate for the AGP in 2023 of  (JORC Code 2012) 16.2Mt @ 2.8g/t Au for 1.44Moz – a 10% increase in grade across the resource base in addition to a 68% increase in higher-confidence Indicated Category ounces.

In 2024 Kalamazoo granted De Grey Mining (ASX: DEG) an exclusive option to acquire the AGP for total of $33m.

Kalamazoo’s Mallina West Gold Project is prospective for both epigenetic gold mineralisation associated with the Wohler Shear Zone, and potential mineralised intrusions similar to those identified at De Grey’s Hemi discovery which is located 50km to the north east.  Kalamazoo has identified 5 highly prospective targets to date.

1. OP (Open Pit) resource: >0.5 g/t, inside optimised pit Rev factor = 1.2
2. UG (Underground) resource: >1.5g/t below Rev factor = 1.2 pit, inside domain wireframes
3. West Olympus OP: >0.5 g/t, inside optimised pit Rev factor = 1.2
4. UG: >1.5g/t below Rev factor = 1.2 pit, inside domain wireframes
5. OP: >0.5g/t above 395mRL (equivalent to base of current pit)
6. OP: Optimised Pit 11 with Indicated + Inferred, > 0.5g/t
7. UG: Below Optimised pit >1.5g/t
8. The previous inferred resource at Romulus remains unchanged at 329kt @ 2.6g/t for 27k oz Au. Romulus was not included in this update and is therefore in addition to the total Resource quoted in the above table
