The Tshipi Borwa manganese mine in South Africa’s Kalahari manganese field has remained profitable and cash positive throughout the Covid-19 lockdown, Sydney-listed Jupiter Mines stated on Wednesday. Overall mining at Tshipi Borwa, which continues to be in a favourable position owing to its low-cost production base, outperformed monthly planned targets, despite the challenges, Jupiter, which is headed by CEO Priyank Thapliyal, reported.
