CHILE · MINING
Key Facts
- —What is happening Chile’s biggest mines face 31 collective wage negotiations in 2027, with state-owned Codelco holding 16 and BHP three, including the Escondida mine’s largest union.
- —Why it matters Chile is the world’s top copper supplier, and a strike at Escondida, the largest copper mine on earth, could tighten supply for US buyers and investors.
- —The numbers Codelco’s talks cover more than 8,429 workers and BHP’s cover 3,721, while the Escondida union has about 2,200 members and its contract ends on 1 August 2027.
- —Who is who Codelco is Chile’s state copper miner; BHP, an Anglo-Australian group with a US listing, runs Escondida and Spence; Plusmining is the mining consultancy that counted the talks.
- —What to watch Spence supervisors bargain first, with their contract ending on 30 November; Escondida’s union is expected to file its demands in early June 2027.
- —Power Index Chile ranks 3rd of 14 in The Rio Times Latin America Power Index, with 63.6 points (October 2026 edition).
- —What it means for you US copper buyers and BHP shareholders should expect labour risk to build through mid-2027, since one newspaper, not the companies, calls an Escondida strike highly likely.
Codelco and BHP will bargain with thousands of Chilean miners next year. One newspaper already calls a strike at Escondida highly likely.
Large mines in Chile will hold 31 collective wage negotiations in 2027, and Codelco, the state copper giant, has 16. Diario Financiero reported the count on Monday, 26 October, using Plusmining data.
It matters to US readers because Chile supplies more copper than any other country, and wage disputes can halt output. BHP, which has a US-listed share, faces three negotiations, including its Escondida mine.
What the 31 Negotiations Cover
Diario Financiero reports that Codelco’s 16 negotiations involve more than 8,429 workers. Codelco said in a statement quoted by the paper that its bargaining cycle runs to August 2028.
BHP has three negotiations covering 3,721 workers, the paper says. Together the two groups account for 19 of the 31 processes.
The Consejo Minero, the industry group of large Chilean miners, publishes its own calendar of contract expiry dates. It lists Escondida’s Sindicato N°1 for mid-2027 with 2,300 workers, close to the 2,200 members in the newspaper’s account.
Escondida Is the Biggest Test
Escondida is the world’s largest copper mine, and its Sindicato N°1 is the key union. Diario Financiero says the contract expires on 1 August 2027 and the union has about 2,200 members.
Workers are expected to submit their proposal in early June, and the company’s final offer is expected around 25 July. Union president Sebastián Liberona says the process will be hard, and the newspaper concludes a strike is highly likely.
Liberona added that the union is preparing a framework agreement for contractors who work at the mine. BHP told the paper that 2027 talks are regulated negotiations and that it hopes for constructive dialogue.
BHP Output Is Already Under Pressure
BHP reported on Tuesday, 20 October, that its copper output in the September quarter was lower than a year earlier. Its chief executive said copper prices were around 50% higher than a year ago.
Metal-market service SMM puts the quarter’s copper output at 400.7 kilotonnes, down 19%. Escondida made 252.6 kilotonnes, down 23% on the year.
SMM says BHP kept its full-year copper guidance of 1.65 to 1.80 million tonnes. BHP also pointed Diario Financiero to a 19% fall in group copper output.
A strike at the mine was averted only on 14 October, hours before it could start. The earlier threat is covered in BHP Pauses Escondida Strike in Chile With 5-Day Talks.
Spence Supervisors Bargain First
The first BHP talks are at Spence, a copper mine in northern Chile. The supervisors’ union there has 462 members, and its contract expires on Monday, 30 November, the paper reports.
The union, led by Juan Ovalle, submitted its proposal on Wednesday, 14 October, seeking better mobility and flexibility terms. Its last negotiation closed at 19.6 million Chilean pesos (about US$19,800).
It now seeks a market-level bonus of 25 to 27 million pesos (about US$25,300 to US$27,300). Conversions use the rate of 26 October from open.er-api.com, about 989.5 pesos per US dollar.
The Consejo Minero calendar also lists the Spence supervisors for November 2026, with 450 workers. It records expiry dates only, not talks or strikes in progress.
Why Union Expectations Are Rising
Plusmining analyst Fiorella Ulloa told the paper that high copper prices and benefits agreed in 2026 could raise union expectations. She also said Codelco’s productivity and cost pressures make its talks demanding.
On Wednesday, 14 October, supervisors at Escondida’s Sindicato N°2 approved a package of 30 million pesos (about US$30,300). Plusmining reports 64.14% voted in favour, and the deal removed a strike threat.
Ulloa flagged Codelco’s El Teniente division, citing accidents and operating difficulties. She said safety and working conditions could weigh more there.
Two workers died at El Teniente on Sunday, 11 October. That accident is covered in Chile’s El Teniente Avalanche Kills 2 Mine Workers.
What It Means for US Readers
Copper goes into US power grids, data centres and electric vehicles, and Chile is the largest single source of the metal. A strike at Escondida or a stoppage at Codelco would be a supply story for US buyers.
The risk lies mostly in mid-2027, so it does not move prices today. Readers can follow the Copper in Latin America 2026 guide for the wider market.
What Is Not Known
The 31-negotiation count and the Codelco and BHP worker numbers come from one newspaper report based on Plusmining data. The Rio Times found no second outlet carrying the full count.
Nobody has set a strike date, and Escondida’s main union has not filed its demand yet. The Escondida membership figure is about 2,200 in the newspaper and 2,300 in the Consejo Minero calendar.
It is unclear which of Codelco’s 16 negotiations are the largest, or how many are early deals. The 12 negotiations outside Codelco and BHP were not itemised.
What Comes Next
Spence supervisors move first, with the contract ending on 30 November. Escondida’s main union is due to file its demands in early June, and the company’s final offer follows around 25 July.
No strike vote or date has been reported, and the October Escondida dispute ended only hours before a stoppage. For the latest mine strike coverage see Copper Falls as Chile’s Centinela Strike Ends.
