Nyrstar updates on impact of state-wide power outage on Port Pirie

29 September 2016 at 7.30 a.m. CEST

Nyrstar NV ("Nyrstar") announces today that severe storms experienced in South Australia throughout Wednesday 28 September 2016 caused a state-wide power loss which led to an outage of the entire Port Pirie smelter including the blast furnace.

A back-up diesel generator at the Nyrstar Port Pirie site sustained the blast furnace for several hours after the power outage commenced. However, with the power outage continuing for a prolonged period, the slag in the blast furnace solidified and the blast furnace cannot be tapped. It is expected that the blast furnace will be down for approximately 10 – 14 days for repairs necessitated by the power outage, negatively impacting Metals Processing EBITDA by approximately EUR 3 - 5 million.

Commenting on the production disruption, Bill Scotting, Chief Executive Officer, said: "We are obviously very disappointed that the power supply in South Australia has failed and the impact that this has caused to the Port Pirie plant. The Port Pirie site is working incredibly hard to ensure we are in a position to restore the blast furnace to full functionality as soon as full power is restored. No other plant damage has occurred and the outage is not expected to have any impact to the Port Pirie Redevelopment schedule."
