Cobre Ltd (ASX:CBE) has delineated new copper-silver targets at the Okavango Copper Project (OCP) in the Kalahari Copper Belt (KCB) in Botswana, where a 1,920-metre diamond drilling program has struck copper-silver mineralisation in 50% of holes.
The anomalous mineralisation was intersected along strike from the neighbouring Zone 5 and Boseto groups held by MMG, which hold resources of 166 million tonnes at 2.0% copper and 26 g/t silver, and 126 million tonnes at 1.2% copper and 17 g/t silver, respectively.
CBE observed bornite (copper-iron), chalcopyrite (copper-iron) and chalcocite (copper-sulphur) as well as typical styles of contact-related copper mineralisation in the drill core, supporting the idea of higher-grade zones and an opportunity to follow the breadcrumbs toward an economic formation of mineralisation.
Highly prospective, underexplored
“Intersecting anomalous copper mineralisation at OCP highlights the prospectivity of this large-scale under-explored project on the doorstep of MMG’s production hub,” Cobre CEO Adam Wooldridge said.
“Drilling, along with ground gravity results, has provided a clear vector for follow-up targeting of high-grade deposits.
“We’re particularly encouraged to see vein-hosted bornite mineralisation in two of our holes, generally a positive indication of proximity to KCB deposits.”
CBE also collected ground gravity data over the project during this most recent drilling program, offering insight into the geological controls on copper mineralisation at the site.
The company believes the combination of its drilling results and indications from the gravity data points to a mineralised setting similar to that at the Zone 5 area in the central portion of MMG’s operations.
Cobre is keen to explore that potential, considering MMG’s Khoemacau Copper mine and exploration tenement acquisition was worth US$1.9 billion.
