From SFR news Major mining hub in Kalahari copper belt

Australia's Sandfire Resources Ltd (SFR) plans to spend additional $71.9 million to expand production at Botswana's newest copper mine as it looks to establish a major mining hub in the Kalahari Copper Belt, the company said on Tuesday.
"In parallel with this development, we are also continuing a major exploration campaign both in the near-mine area as well as across our extensive landholding in the Kalahari Copper Belt aimed at defining additional ore sources that can feed into our expanded processing hub at Motheo or support the development of new production centres across the region,” Simich said.
The emerging copper belt could help Botswana diversify beyond its mainstay diamond mining, which contributes 70% to its export revenue.
