NewPeak Metals confirms a large-scale gold-zinc-silver system at Las Opeñas with 663m at 0.41 g/t AuEq; assays from five more holes due in 3-6 weeks will test for higher-grade zones.
NewPeak Metals (ASX: NPM) has confirmed a large-scale gold-zinc-silver system at its Las Opeñas project in San Juan Province, Argentina. The first diamond hole of the 2026 program returned 663 metres at 0.41 grams per tonne gold equivalent from surface to the end of hole. That intercept included 0.16 g/t gold, 0.65% zinc, and 4.53 g/t silver.
Hole 26-LODH-023 was collared about five metres south of a historical hole Genesis Minerals drilled in 2012. That earlier hole returned 115 metres at 0.58 g/t gold, 0.65% zinc, 3.5 g/t silver, and 0.24% lead from 18 metres to the end of hole. NewPeak sees the proximity and consistency of the two intercepts as early evidence of continuity across the breccia system.
The company has completed 2,464 metres of diamond drilling across six holes. Assays from the remaining five holes – another 1,802 metres – are due within three to six weeks.
Las Opeñas contains a reinterpreted 800-metre by 600-metre breccia zone that had previously only been tested to shallow depths. NewPeak’s latest drilling targeted deeper portions of that zone, which sits within a rhyolitic complex associated with phreatic breccias and strong argillic alteration. The company has mapped two distinct mineralisation phases: broad silver-dominant mineralisation in phreatic breccias and gold-silver-polymetallic mineralisation in discrete hydrothermal breccias.
Managing director Mark Purcell said the first hole drilled at Las Opeñas since 2019 – and the first diamond hole since 2014 – had confirmed a large-scale system from surface.
“Uncovering a system of such substantial scale is exactly what we hoped to achieve,” Purcell said. “The presence of meaningful zinc and silver credits is also very encouraging given both metals have been formally recognised as critical minerals by the US Geological Survey in 2025.”
NewPeak believes the polymetallic character of the project improves its strategic positioning as markets focus on secure critical mineral supply chains. Permitting is already in place for up to another 7,500 metres of drilling. The company said favourable results from the remaining holes could support a push toward a maiden resource.
For traders watching the junior explorer space, the next assay batch will test whether the broad mineralised envelope at Las Opeñas carries higher-grade zones that could justify a resource estimate. The breccia scale and the structural setting are the right ingredients. The market needs grade continuity across multiple holes. Without that, the discovery stays at wide-interval confirmation. The next assay results, due within three to six weeks, will provide the first real test of whether this system has the grade density to become a drill-out story.
