Limpopo has seen a spike in Covid-19 cases within 24 hours, with the majority of it recorded in the mining areas of the province's Sekhukhune District.
The province on Wednesday stood at 93 cases - but, by Thursday, the number had risen to 121, to the ire of authorities who cautioned that some areas may remain under Level 4 regulations after 1 June.
The Sekhukhune District, at some stage during the lockdown, had zero cases, but now has a high number since the resumption of mining activities.
It is also expected that the number of cases in the Vhembe District will increase when mining activity resumes at Venetia Mine, which employs thousands of workers.
Limpopo Premier Stan Mathabatha said the government was worried about the situation at the mines, and it was the reason behind last Sunday's meeting with Mineral Resources and Energy Minister Gwede Mantashe and mining management.
