Belararox is stepping things up at the Kalahari copper project, with a big airborne EM survey and diamond drilling locked in for the coming quarter.
- Survey to target above promising copper contact zone
- 1000km2 AEM survey to test northern strike corridor
- Upcoming diamond drilling to hit most prospective areas
Special Report: Belararox has a new team on the ground in Botswana, using airborne EM and magnetic surveys to pick out the best drill targets before diamond drilling kicks off next quarter at the Kalahari copper project. This fieldwork sets things up for drilling, with the team using a tailored exploration model to zero in on the best hotspots before the next phase.
For Belararox (ASX:BRX) , the northern corridor is just one part of the huge Kalahari copper project. The area covers about 3900km2 east and south of Maun, and it’s less than 100km from MMG’s Khoemacau copper hub, where an expansion to 130,000tpa of copper production began in February and studies have been commissioned to grow to 200,000tpa.
That puts the geology of the region well and truly in world class territory. With a refreshed exploration plan, BRX’s team will use airborne geophysics and magnetic surveys ahead of diamond drilling.
CEO Will Dix said Belararox will hit only 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 says it is using a tried and tested Kalahari copper belt playbook to map the key rock contact where copper deposits tend to sit, helping it narrow a big ground package down to the best drill targets fast. In 2026, the focus will be on tenure along strike from the Khoemacau hub, where the company hopes the same geological setting could point to another standout discovery. This is the first time Belararox is exploring the promising northeast part of its ground, so there’s a real chance for an early win.
Better targeting
Belararox is using the Spectrem Plus Airborne EM system, which is top-notch for geophysical exploration. It’s got plenty of power and can map under cover with high-tech electromagnetic tools. It can map both shallow ground and deeper geology, even past 700m deep, and does it all in high detail. The survey will map the geology, look for conductors in the top 700m, estimate how thick the cover is and spot any fault systems.
Finding a needle in a haystack
By zeroing in on the strongest targets first, Belararox can make exploration across its enormous project area far more efficient than a needle-in-a-haystack search. The company is looking to leverage its large 4300km2 tenement package in pursuit of a significant new regional discovery. The Kalahari Copper Belt is already home to world-class sediment-hosted Cu-Ag deposits clustered around hubs such as MMG’s Khoemacau and Sandfire’s Motheo, with majors like BHP also exploring in the region.
