Nyrstar NV announced that that it has had to declare force majeure under a number of its agreements, due to an unplanned stoppage of production at the Port Pirie smelter that commenced on 28 May 2019. Production is expected to resume at the end of June 2019. The Blast Furnace was intentionally shut down in May 2019, to allow the Top Submerged Lance Furnace to re-establish an adequate stock of product TSL slag feed for the Blast Furnace, following an extended planned shutdown of the TSL in April 2019. The Blast Furnace restart was unexpectedly delayed by a steam eruption in the Refinery, and a failed Blast Furnace water jacket.

On 5 June 2019, a failure of the TSL main process gas duct, between the Waste Heat Boiler and Evaporative Gas Cooler, required a further shutdown of the TSL for remedial work. Consequently the further extended Blast Furnace outage now requires a partial dig out of the Continuous Drossing Furnace, essential for treatment of all lead output from the Blast Furnace, as it has now fully solidified. It is expected that the Blast Furnace and TSL will restart at approximately the same time at the end of June 2019.
