125 years of the Port Pirie smelter | PHOTOS

125 years ago, the now famous Port Pirie smelter began its operations.  

On June 27,  1889 the first shift went into work at 4am at what was then known as the British Broken Hill Smelters.  

Friday the Nyrstar Management team handed out free cake and coffee sachets at the gate from 5.30am to 8.30am to over 500 employees and contractors as a small celebratory token.  

The workers were given the cake between 5.30am and 8.30am as they were coming into work.   

Nyrstar have provided the following information from their archival records: 

 On June 27 1889, the South Australian Chronicle reported: 

“The British Broken Hill Limited Smelters began today, the first shift going on at 4 o’clock. So far everything is going smoothly.” 

And then the following day they further reported. 

“The Smelters are now running smoothly, one furnace being in full blast. The first lot of bullion was run off at midnight last night, and the start is considered most satisfactory taking into account the difficulties with the new machinery.”

And so the story of the Port Pirie smelter began, with millions of tonnes of metal being produced and many thousands of people being employed – often generations of the same family – throughout our continuous 125 year history.

A Nyrstar spokesperson said the Port Pirie site will further acknowledge and celebrate their history later this year with the launch of a history book about the smelter. 

The Nyrstar board recently approved a redevelopment with support from the State Government  

"....many things have changed and improved throughout our diverse history, the commitment of our employees and the ability the site has to overcome the many challenges faced to ensure we have remained operational is a story in itself," the spokesperson said.
