Terrain Minerals Limited has completed an ultrafine fraction soil sampling programme at its Carlindie Project, located approximately 90 kilometres southeast of Port Hedland in Western Australia.

The 100% owned project previously underwent a conventional soil survey in October 2025 that outlined a multi-element gold-pathfinder anomaly spanning approximately four by three kilometres. The latest field campaign comprises 538 sample sites organised across three components, designed to test two priority magnetic targets and evaluate the geochemical method over transported cover.

First-pass gold assays from the earlier 828-sample survey were also released, returning 21 values above the 0.005 ppm detection limit out of 709 samples analysed. The peak value reached 0.119 ppm gold at sample C155, though the results proved low-order and spatially uncoordinated.

The current work functions primarily as an orientation exercise. Terrain expects to receive assay results from the ultrafine fraction sampling in the fourth quarter of 2026.

“This survey is deliberately an orientation exercise. Before we spend real money covering the whole machine-learning footprint, we want to know that the ultrafine-fraction method gives us a bedrock signal through the cover at Carlindie. It is a low-cost way of answering that question.”

— Justin Virgin, Executive Director

Subject to the orientation results, Terrain plans to extend ultrafine fraction soil sampling across the balance of its machine-learning target areas within tenements E45/6524 and E45/6951 during the second quarter of 2027.
