A major chapter in Mount Isa’s history has come to a close with the shutdown of the century-old underground copper mine, a staple of the city’s economy and identity.
The mine, owned by Swiss multinational Glencore, has ceased production after 70 years, resulting in nearly 500 direct job losses.
The mine’s closure brings an end to a daily ritual for Mount Isa residents, who had grown accustomed to the twice-daily blasts caused by explosives used to extract valuable metals like copper, zinc, and silver.
The silence will be a significant adjustment for the community, according to Mount Isa Mayor Peta MacRae.
The mine’s history dates back to 1924, initially operating as a lead, zinc, and silver mine before shifting its focus to copper in the 1950s to support the war effort.
The subsequent surge in global copper demand led to the launch of a dual-stream copper and lead-zinc-silver production, cementing the mine’s importance in the region.
Historian and archivist Barry Merrick noted that the mine’s legacy is a testament to the finite nature of the earth’s mineral resources.
“It doesn’t keep growing; if you take it out, nothing can replace it,” he said.
While the copper mine’s production may have ceased, Glencore Metals Australia’s interim chief operating officer, Troy Wilson, emphasized that the mine’s history and significance will continue to be felt in Mount Isa.
The community is encouraged to reflect on the mine’s impact and consider the opportunities that lie ahead.
As the city adjusts to this new reality, residents are urged to share their stories and memories of the mine’s history.
