Premier African Minerals Limited (LON:PREM) expects the processing plant at the RHA Tungsten in Zimbabwe to be switched on this week.
Premier gave its contractor APT a deadline of July 6 to rectify the problems with the new plant at 49%-owned RHA.
Today it said screens and plant modifications had been completed with the completion of electrical circuits to take place over next two days.
George Roach, chief executive, said: "We expect to start running the plant later this week, once the electrical reticulation is finished."
Once operations recommence, a joint assessment will be conducted with the plant supplier Roach said last month.
