Premier African Minerals (AIM:PREM) said ore from the run-of-mine pad is now being fed through the newly installed flotation plant at its Zulu project.
The AIM-listed miner (AIM: PREM), which develops lithium, tantalum and tungsten projects in Southern Africa, described initial observations as positive but said it is still early in the optimisation process so recovery characteristics and overall plant performance remain premature to assess.
"This is a very positive step in the re-start of Zulu," Graham Hill, managing director, said.
The company said ongoing analysis and plant optimisation work is under way and that further updates will be provided as performance data matures.
Beaumont Cornish is named as the company's nominated adviser and Shore Capital and CMC Markets are listed as stockbrokers.
Premier said it will publish further operational progress updates as the flotation plant optimisation proceeds.
