Kalamazoo Resources has initiated a drilling programme of approximately 14,000m at its Ashburton Gold Project in Western Australia’s Pilbara region.
The initiative involves drilling at the Mt Olympus Deposit, part of the wider project, utilising both reverse circulation (RC) and diamond drilling methods.

This effort aims to enhance geological confidence in the resource model at Mt Olympus and assist in progressing ongoing mining and pre-feasibility studies.
The Ashburton Gold Project currently has mineral resources of approximately 16.2 million tonnes (mt) at a grade of 2.8 grams per tonne (g/t) gold, amounting to around 1.44 million ounces (moz) across four mining leases.
The Mt Olympus Deposit contains an estimated mineable quantity of 772,000oz at 2.53g/t gold, based on a gold price of A$4,500/oz ($3,147/oz).
Kalamazoo’s drilling programme aims to elevate inferred resources to an indicated classification.
Drilling efforts are concentrated on resource infill areas within the existing deposit, following a drill spacing of approximately 20m × 20m.
The company is collaborating with DDH1 for diamond drilling and with Strike Drilling for RC work.
The scoping study also indicates that higher gold prices could considerably increase pre-tax free cash flow from approximately A$747m at the base case to roughly A$1.39bn at A$6,000/oz.
Recent exploration beneath the Mt Olympus open pit hints at additional significant underground resources ranging from 350,000 to 500,000oz at grades of 2–3.8g/t gold.
These potential resources are not included in the current scoping study but highlight Ashburton’s potential as a long-life, regional-scale development prospect.
Kalamazoo executive director Ben Ackerman said: “With the Phase 1 Growth drilling programme complete, we have commenced a major resource infill programme aimed at increasing resource confidence and supporting the Mt Olympus pre-feasibility study.
“An RC rig is already on the ground, delivering rapid coverage across the deposit, including targeted infill of inferred resource areas to support potential conversion to higher confidence categories.
“Two diamond rigs are also scheduled to commence in early April 2026, expanding drilling capacity and capturing the critical geological and geotechnical data needed to underpin the next stage of project development.”
