Survey to Target Promising Copper Contact Zone
Belararox is stepping up its exploration efforts in Botswana, focusing on a promising copper contact zone. The company has initiated a 1000km² airborne electromagnetic (AEM) survey to test the northern strike corridor of the Kalahari copper project. This survey aims to identify the most prospective areas for diamond drilling, which is set to commence in the next quarter.
The fieldwork is part of a broader strategy to refine drill targets using a tailored exploration model. This approach allows the team to focus on the most viable locations before moving forward with drilling activities.
For Belararox (ASX:BRX), the northern corridor represents just one segment of the vast Kalahari copper project, which spans approximately 3900km² east and south of Maun. The region is less than 100km from MMG’s Khoemacau copper hub, where an expansion to 130,000tpa of copper production began in February. Studies are also underway to increase production to 200,000tpa, highlighting the area’s potential as a world-class geological site.
With a refreshed exploration plan, BRX’s team will use airborne geophysics and magnetic surveys ahead of diamond drilling. CEO Will Dix emphasized that the company will focus only on the most promising spots. “We believe that the airborne electromagnetic survey will provide a key pillar of our exploration approach,” he said. “We expect to be regularly updating Shareholders throughout the coming months on our progress.”
Improved Playbook
Belararox is employing a tried and tested playbook from the Kalahari copper belt to map the key rock contact where copper deposits typically occur. This method helps narrow down the large ground package to the best drill targets quickly. In 2026, the focus will be on tenure along the strike from the Khoemacau hub, where the company hopes the same geological setting could lead to another significant discovery.
Figure 2 illustrates the location of PL2743 and PLO770, along with the AEM survey area. This marks the first time Belararox is exploring the promising northeast part of its ground, offering a real chance for an early win.
Better Targeting
To enhance its exploration efforts, Belararox is utilizing the Spectrem Plus Airborne EM system. This advanced technology is highly effective for geophysical exploration, offering powerful capabilities to map under cover with high-tech electromagnetic tools. It can effectively map both shallow ground and deeper geology, even beyond 700m depth, with high precision.
The survey will assess the geology, identify conductors within the top 700m, estimate the thickness of the cover, and detect any fault systems. By focusing on the strongest targets first, Belararox can make exploration across its extensive project area significantly more efficient than a traditional needle-in-a-haystack search.
The company is leveraging its large 4300km² tenement package in pursuit of a significant new regional discovery. The Kalahari Copper Belt already hosts world-class sediment-hosted Cu-Ag deposits clustered around hubs such as MMG’s Khoemacau and Sandfire’s Motheo. Major players like BHP are also actively exploring in the region, underscoring the area’s potential.
