- Lammerlaw fieldwork completed with structural mapping and geochemistry sampling
- Tungsten exploration priority elevated at Granite Creek
- Historical tungsten mineralisation at Croesus with grades up to 42.6%
- Tungsten market has structurally changed, with prices rising significantly
Critical Resources (ASX: CRR) is increasing its focus on tungsten after receiving positive results from first-pass field programs at the Lammerlaw gold project and Croesus gold-tungsten project in New Zealand.

At a time when global tungsten demand and prices have taken off, field verification at Croesus has confirmed greisen alteration at locations within and beyond the historical sample sites.
Critical Resources has ramped up its NZ exploration plans after it completed the transfer of five prospecting permits in the Otago and Reefton in March.
The Croesus field program covered both the structurally controlled gold-antimony lode system across the Croesus and Minerva gold-antimony trend and the greisen-hosted tungsten system within the 183 sq. km prospecting permit.
Activities included targeted structural mapping, rock chip, stream sampling, and ground-truthing of historical sample sites.
MD, Tim Wither, told shareholders field mapping of Granite Creek has elevated the tungsten target in the company’s near-term work program.
“Receiving approval for the NZ permit transfer and having the field team at Lammerlaw within days reflects the pace we have committed to. Both first-pass programs were delivered safely and effectively despite challenging weather,” he said.
“The standout was Granite Creek. The team confirmed greisen alteration and outcropping quartz vein structures across multiple locations, including at the historical rock sampling sites that returned up to 42.6% WO3, elevating Granite Creek as a priority.
“With tungsten formally designated a strategic critical mineral across the US, EU, UK, Japan, New Zealand and Australia, and APT prices having risen more than eight times since January 2025, confirming a Western-aligned greisen-hosted tungsten target in this market environment is strategically significant.
“Near-term activity plans continue across the New Zealand portfolio – assay results from Lammerlaw and Croesus through May and June 2026, follow-up mapping at Granite Creek and follow-up drilling at the Cap Burn gold project in Central Otago.”
Samples from Granite Creek have been dispatched to the laboratory with assay results from the Croesus program expected in early June.
CRR is steady at 0.8¢. Mkt cap $25.55M.
