Trigon Metals has defined drill-ready targets at its Kalahari Copper Project in Namibia following the completion of a drone-based aeromagnetic survey and advanced 3D data inversion.
The survey, which covered ground near the Fiesta-Fortuna Prospect held by Noronex Limited, has provided the company with a clear map of structural features and mineralisation potential across a key part of the Kalahari Copper Belt.
The work was carried out in an area with thick sand cover of more than 40 metres, where traditional surface exploration methods are ineffective.
By deploying high-resolution airborne geophysics, Trigon was able to penetrate beneath the sand and reveal regional anticlines, domal structures, and magnetic anomalies associated with copper-bearing formations. Among the highlights are ellipsoidal magnetic lows interpreted as Ngwako Pan cored anticlines and flanking magnetic highs linked to the D’Kar Formation.
One of the most promising targets is the Heimat Fold Closure, part of the same domal system as Fiesta-Fortuna but occurring higher in the stratigraphy.
While most deposits in the copper belt are located near the Ngwako Pan/D’Kar contact, Trigon’s interpretation suggests that copper mineralisation is also associated with domes, anticlines, and secondary faulting.
The Heimat target fits this model, lying along a hinge zone with known mineralisation immediately to the east.
Another target, the Bushman Dome, is located south of Heimat and features a large Ngwako Pan cored dome. Both zones are considered highly prospective for semi-stratiform copper deposits, which characterise many of the belt’s most significant discoveries.
Through the 3D inversion of magnetic data, Trigon has determined the relative depth of the prospective contacts, enabling precise drill planning.
Additional anomalies identified include cigar-shaped magnetic highs, interpreted as parasitic folds, and linear structures believed to be related to late Damaran-age thrusting and faulting. Data refinement is ongoing as the company prepares its maiden drilling programme.
Trigon President and CEO Jed Richardson described the development as a major step forward. He said the exploration had now moved beyond reconnaissance into a focused, target-driven phase.
“The survey results have given us a clear picture of where the most prospective structures lie, and we’re now positioned to advance towards drilling with a high degree of confidence,” he noted.
Vice President of Exploration, Dr Andreas Rompel, added that the geological interpretation pointed to significant folding along a west-southwest axis and a clear contact between two lithologies, defining a compelling drill target. “We are excited to advance the next phases of exploration on what we believe is a highly prospective and prolific project,” he said.
The Kalahari Copper Belt stretches across Namibia and Botswana and is regarded as one of the world’s most promising underexplored copper districts.
The belt has drawn global interest with multiple companies, including Noronex, Sandfire Resources, and Cupric Canyon, making significant discoveries in recent years. Trigon’s progress in Namibia underlines the growing importance of this region as a potential new source of African copper production.
