Wedoany.com Report on Mar 10th, Noble Resources has discovered a new porphyry copper system through diamond drilling at its Cuprita project in northern Chile. This exploration campaign, initiated in January 2026 based on research by the 2025 technical team, identified key geological and geophysical features.

The drilling altered the exploration landscape, with hole CUP004 intercepting over 100 meters of copper mineralization. While the company awaits laboratory assays to confirm commercial grades, preliminary data is positive. The earlier CUP003 hole provided geological vectors that helped the team accurately target the core of the hydrothermal system.

Geologists observed a dramatic change in rock starting from a depth of 218 meters, recording an increase in tourmaline veins and the formation of intrusive breccia. Portable XRF measurements showed localized copper peaks reaching 1,700 ppm. In the interval from 285 to 382 meters, the team identified a mineralized zone rich in sulfides with increased quartz vein density, with copper grades reaching 2.9% in chrysocolla stringers and 2.6% in pyrite-chalcopyrite zones.

This transition from an oxidized "leached cap" to primary sulfides indicates the company has penetrated the mineralized domain it has been seeking since exploration began. Geophysical parameters place Cuprita in a structural setting similar to renowned deposits like El Salvador, Spence, or Sierra Gorda. The alteration zoning confirmed by holes CUP-003 and 004 is characteristic of major Andean porphyry systems.

Vernon Arseneau, Operations Director of Noble Resources, stated: "After exploring for this type of deposit in Chile for over 35 years, it is rare to find such an extensive leached cap, accompanied by mineralization and associated geophysical anomalies, that has never been drilled. This is an exciting start for the project." With the commencement of hole CUP005 just 200 meters from the discovery, the company has become one of the junior mining companies to watch in 2026.
