Critical Resources Limited has completed a 5.4 km soil sampling transect across the Lammerlaw project in Central Otago, New Zealand, returning multiple arsenic, antimony and tungsten anomalies centered on the Stony Creek target.

The follow-up program comprised 143 new soil samples collected across the western side of the 410 km² permit area. Results identified multiple pathfinder anomalies concentrated within an approximately 3.2 km section of Stony Creek. Sample A1583 returned 238 ppm corrected arsenic and 25 ppm antimony using portable XRF, representing approximately 14 times the program median of 17 ppm arsenic. Ten samples across the program returned at least 30 ppm corrected arsenic, which marks the approximately 95th percentile of the population.

Other results include sample A1591 with 31 ppm antimony and 36 ppm tungsten, and sample A1682 with 30 ppm corrected arsenic and 29 ppm tungsten. Portable XRF readings are qualitative spot measurements and are not equivalent to laboratory assays. No gold grades have been determined by the pXRF program, and no drilling has been completed anywhere on the permit to date.

“We have identified multiple arsenic-antimony-tungsten anomalies across Stony Creek rather than a single isolated response, and they fall within the same corridor as the historic antimony workings, the elevated tungsten geochemistry and the airborne electromagnetic feature that led us to prioritise the target in the first place. Independent datasets pointing at the same ground are what give us confidence we are vectoring in the right direction.”

Critical Resources holds a 1,694 km² gold-antimony exploration footprint across New Zealand's Otago and Reefton regions through its wholly-owned subsidiary Goldfire Resources Limited.

For upcoming work, Critical Resources plans to submit selected soil samples from the Stony Creek target for accredited laboratory analysis, including gold, alongside structural mapping and rock-chip sampling to determine which anomalous areas warrant drill testing. In the surrounding district, Santana Minerals reported high-grade gold hits including 24.4m at 10.9 g/t gold from its Bendigo-Ophir project in July 2026.
