Kobrea Exploration (CSE:KBX) CEO James Hedalen says there is more to be discovered across its Argentinian portfolio, after discovering a 1,250m by 500m hydrothermal breccia body in the Cuprum Trend at the Western Malargüe Copper projects.
Target KBX-17 was first identified by Kobrea in March 2025, when field crews noticed a multi-kilometre colour anomaly. A follow-up program comprising detailed geological mapping and rock chip sampling was completed in December 2025, which outlined the anomaly.
The strongly leached and weathered hydrothermal breccia is anomalous in copper, with numerous samples grading between 161 parts per million (ppm) and 408ppm copper.
In the immediate proximity to the breccia body, samples of the host rock diorite containing up to 1.6% copper were collected. Several other smaller hydrothermal breccia bodies within the diorite stock were also mapped, including a 300m by 150m magnetite cemented breccia with samples up to 223ppm copper.
Kobrea is planning an induced polarisation survey that will cover the exploration target to investigate the potential of an underlying porphyry system.
Hedalen says the interpretation of the company’s field geologists is that this target is a vertically-zoned, sulphide-cemented hydrothermal breccia originating from a porphyry system at depth.
“This result highlights the exploration upside across this exceptional land package and validates our exploration thesis that there is more to be discovered across these projects, beyond what has been outlined by previous operators,” the CEO says.
Kobrea’s field crew is currently onsite for a phase one diamond drill program, targeting the El Perdido porphyry system – which is host to a porphyry copper-gold-molybdenum system that has been defined at surface but has not seen any drilling to date.
Drilling will test the centre of the system, where the highest density of quartz stockwork veining associated with a potassic alteration assemblage occurs and which has been intruded by a series of inter-mineral hydrothermal breccias.
The company holds the right to earn a 100% interest in seven projects totalling 733km2, comprising the Western Malargüe Copper Project in the southwestern Mendoza Province of Argentina
