Kalamazoo Completes Mt Olympus Resource Drilling Program

15 July 2026 | Western Australia - Kalamazoo Resources has completed the Mt Olympus Resource Definition Drilling Program at its 100%-owned Ashburton Gold Project in Western Australia, with new assays continuing to show broad, high-grade gold mineralisation.

The completed program included 72 holes for 13,726m, with results now received for almost half of the holes.

The latest assays included a strong intercept of:

• 31m at 5.2 g/t gold from 49m, including 15m at 7.5 g/t gold from 53m

Across the first 34 holes reported, Kalamazoo said the program has returned 16 significant intercepts above 50 gram-metres, supporting continuity of broad, high-grade mineralisation within the Mt Olympus system.

The company said the infill drilling has reduced drill spacing to around 20m by 20m, supporting potential conversion of additional Inferred Resources into the higher-confidence Indicated category.

Why it matters: Mt Olympus is the foundation deposit within Kalamazoo’s 1.44Moz Ashburton Gold Project, located about 35km south-east of Paraburdoo.

The drilling has confirmed mineralisation within the existing resource extents and also intersected mineralisation beyond the current resource envelope, but still within the conceptual Scoping Study pit shell. This could support future growth in mining inventory.

Kalamazoo is targeting an updated Mineral Resource Estimate in Q4 2026, followed by a Pre-Feasibility Study in Q1 2027.

The company has also commenced underground resource growth drilling at Mt Olympus, targeting extensions beneath and down-plunge of the current Scoping Study pit. Additional drilling is also continuing at the nearby high-grade Peake Deposit.

For Western Australia’s gold development sector, Ashburton remains a project to watch, with resource definition complete, growth drilling underway and the project moving toward a PFS.
