When Trigon Metals Inc. closed the book on its Kombat Mine in mid-2025, it wasn’t just divesting a historic Namibian copper producer—it was reshaping its future. The sale to Horizon Corporation, valued at approximately US$24 million and structured with staged payments, enabled Trigon to alleviate the heavy capital demands of operating Kombat while maintaining a steady stream of cash inflows.
For management, this freed bandwidth and resources to pivot toward the company’s new flagship: the Kalahari Copper Project (KCP).
Trigon acquired its interest in the Kalahari Copper Project in March 2024.
The deal gave the company the right to earn up to a 70 per cent stake through Base Metal Investments, structured via a private Mauritius company.
As part of the transaction, Trigon issued 13.6 million shares and committed to spending US$1 million on exploration over two years, alongside an initial cash payment of US$60,000 to the vendor, Ongwe Minerals. The project itself is vast, covering about 963,000 hectares along 280 kilometres of the Kalahari Copper Belt, with major neighbours including Sandfire Resources to the northeast and Rio Tinto to the southwest. Historical data from nearby prospects, such as Fiesta-Fortuna, have demonstrated notable copper and silver grades, underscoring the project’s potential.
In September 2025, Trigon announced the completion of a drone-based aeromagnetic survey over a key area of KCP.
The company finalised the processing and 3D inversion of the data, enabling the interpretation and definition of highly prospective exploration targets that will anchor its upcoming exploration campaigns.
The survey zone was carefully chosen for its favourable stratigraphy and structural features, as well as its proximity—just four kilometres west—of Noronex’s Fiesta-Fortuna prospect.
Thick Kalahari sand cover, exceeding 40 metres in places, necessitated the use of high-resolution airborne geophysical methods to see below the surface.
The results revealed a structural picture dominated by two regional-scale, doubly plunging anticlines.
Within these, ellipsoidal magnetic lows are interpreted as tight Ngwako Pan Formation-cored anticlines, flanked by magnetically positive anomalies associated with the D’Kar Formation.
These formations are critical in the Kalahari Copper Belt, where mineralisation is typically semi-stratiform and controlled by domes, folds, and faulting.
Among the standout targets is the Heimat Fold Closure, lying within the same domal structure as Fiesta-Fortuna but interpreted higher in the stratigraphy, within the D’Kar Formation rather than at the traditionally targeted Ngwako Pan/D’Kar contact.
Trigon interprets KCB mineralisation as having both diagenetic and epigenetic origins, with significant deposits often tied to regional anticlines, domes, and second-order structures.
The Heimat Fold Closure fits this model, with known mineralisation along strike to the east.
To the south lies the Bushman Dome, a large Ngwako Pan-cored dome that presents another significant exploration target. Both Heimat and Bushman demonstrate how Trigon is targeting domal features with intact structural “roofs” or exposed contacts—settings known to host copper-silver deposits across the belt.
Using 3D inversion of the magnetic survey, Trigon has been able to map the relative depth of the prospective Ngwako Pan/D’Kar contact along the hinge zone of the Heimat Dome.
This information will guide the design of the company’s maiden drilling program at KCP.
Additional anomalies have also been defined, including cigar-shaped magnetic highs that are likely linked to parasitic folding, and linear features interpreted as late Damaran-age faulting and thrusting.
These second-order features are often critical controls on high-grade mineralisation. Further interrogation of the data is underway to refine drill targets before rigs are mobilised.
The Kombat sale allowed Trigon to pivot away from the pressures of mine rehabilitation and production funding. Instead, the company is focusing on pure exploration—leaner, more flexible, and potentially higher-impact. Horizon’s staged payments ensure a steady cash inflow, while KCP provides the geological scale and prospectivity to underpin Trigon’s next growth story.
