Chile's Escondida Copper Mine: Union Refuses BHP's Request to Pause Contract Talks After Worker Death
Published on 09/26/2026 at 04:01 | Editorial boerse-global.de
Union representatives at Chile's Escondida copper mine have turned down a request from operator BHP to suspend ongoing collective bargaining, insisting that negotiations proceed on schedule despite a fatal accident earlier this week.
The company had sought the pause following the death of a worker at the site. Both Union No. 1 and the union representing supervisors and administrative staff rejected the proposal, pressing instead for talks to continue as planned.
Accident Halts Operations, Then a Gradual Restart
The incident occurred on Wednesday, 23 September 2026, when a 53-year-old employee was killed while carrying out maintenance work. BHP responded by halting all mining activity at the northern Chile site, and the national mining and geology authority, Sernageomin, dispatched a regional team to investigate what went wrong.
After the affected area was shut down, the company began bringing operations back online in stages on Thursday, 24 September 2026.
Chilean practice generally requires mining companies to obtain confirmation from state inspectors that conditions are safe before fully resuming work following a fatal accident. According to the company, certain areas ran at reduced capacity for a period.
Union No. 1 criticised the speed of the restart, saying it had not been informed of the plans in time. Workers' representatives further alleged that much of the operation continued as normal and was only partially stopped once Sernageomin intervened. Union sources also said safety warnings issued before the accident had gone unheeded.
A 15-Day Pause Requested — and Denied
Against the fallout from the death, BHP management asked for a 15-day suspension of negotiations with supervisors and specialised staff. The unions said no. Tensions remain high because the current collective agreement covering roughly 1,020 supervisors and administrative employees expires at the end of September. That group accounts for about a quarter of the mine's direct workforce.
Union leadership has already recommended that members reject BHP's latest offer, with a vote scheduled for 28 to 30 September 2026. A strike is considered likely if the proposal is voted down. Union No. 1, which represents around 2,300 workers, has signalled its support for possible industrial action.
On the table from the company: a net signing bonus of 23.5 million Chilean pesos under a 36-month contract. The union's counter-demand has been valued by people familiar with the process at a total of USD 69.5 million.
What a Stoppage Would Mean for Global Copper
Escondida is the largest copper mine in the world. In fiscal year 2026 it produced 1,261,000 tonnes of copper, according to BHP — a figure that Chile País Minero calculates works out to roughly 3,450 tonnes per day. A prolonged halt could tighten global supply considerably; a one-week production loss is estimated at about 24,000 tonnes.
For the coming fiscal year 2027, BHP forecasts output of between 1 and 1.1 million tonnes, citing declining ore grades. The company holds a 58.5% stake in the mine and serves as its operator.
Rio Tinto holds 30%, while JECO holds 12.5%. BHP shares edged up 0.1% on the New York Stock Exchange on Thursday, 24 September 2026, closing at USD 85.03, after falling 3.3% the previous day.
