Narryer Metals (ASX:NYM) is planning early 2027 exploration at its Redhill Copper Project in southern Chile after stockpile samples returned 14.9% copper.
Three samples were collected from historical stockpiles at the Cutters Cove area during an August 2026 due diligence trip.
Cutters Vein returned 14.9% copper (Cu) and 1,830 parts per million (ppm) bismuth (Bi). Angelia Vein returned 14.35% Cu and Cristina Vein returned 8.7% Cu with 209 grams per tonne silver (Ag).
The assays support historical drilling and underground channel results that identified zones above 4% Cu at the Cristina and Cutters mines. Narryer will investigate the controls on these zones for future drill targeting.
Bismuth is not included in the existing mineral resource estimate, which comprises an inferred resource of 4.3 million tonnes (Mt) @ 1.7% Cu, 33g/t Ag, and 0.3g/t gold (Au) at Cutters Cove.
Bismuth prices range from US$45,000 ($63,960) to US$70,000 a tonne, with China controlling about 88% of world production, according to Narryer.
Redhill also hosts an exploration target of 16–49Mt @ 1.2–2.6% Cu, 0.4g/t Au, and 34–55g/t Ag at Cutters Cove, which the company says highlights potential resource growth.
The target is conceptual, and further exploration is required before any mineral resource can be estimated.
Narryer has agreed to acquire 100% of Redhill Magallanes, which owns the project. The deal remains subject to regulatory conditions precedent, which must be met by 31 December 2026.
Executive Chairman Richard Bevan says the company wants to understand what governs the ‘high-grade’ zones before it drills.
“A primary aim of the upcoming field program is to identify any structural controls to better understand the massive sulphide mineralisation at Redhill,” Bevan notes.
Bevan says bismuth could add value as a by-product of a future concentrate, alongside copper, silver, and gold.
Narryer Metals is an Australian explorer advancing the Redhill Copper Project in Chile, alongside critical mineral and lithium assets across Australia and Canada.
