BHP Shares Slide, As Escondida Copper Expansion Overshadowed

BHP shares (ASX:BHP) fell 2.31% today to close at a six week low of A$57.51, as markets look to work through a couple of conflicting stories.

On the one hand, the company secured a critical environmental permit to unlock up to US$14.7 billion in copper expansion projects at its flagship Escondida mine in Chile. Also coming today however was news that strike action is looming at it’s Port Hedland site. The action is said to take place on the 16th July, and would involved just over half of the 450 employees across port operations at one of the key parts of the iron ore segment at BHP.

The market reaction to the downside on balance comes as BHP had warned in the past that each day of shutdown at the site could carry a cost of A$129million. That is no small price to pay, although there is a little over a week to seek a resolution before the date in question.

The Escondida Expansion

The Antofagasta Environmental Assessment Commission granted initial approval for early works at Escondida, covering sulphide leaching and electricity infrastructure improvements valued at approximately US$1.3 billion. The clearance opens the door to a multi-year investment program that could reach US$14.7 billion across mine and processing upgrades at the world’s largest copper operation, where BHP holds a 57.5% stake alongside Rio Tinto’s 30% interest and a Japanese consortium.

BHP expects to invest between US$10.7 billion and US$14.7 billion across its Chilean operations in coming years, with the Escondida program anchored by a US$5.9 billion new concentrator plant that will not deliver first production until the early 2030s. That long payback profile, combined with broader risk-off sentiment in resources today, may explain why a clearly positive regulatory milestone failed to lift the stock.

BHP has framed its copper strategy around structural demand tailwinds from decarbonisation and data centre infrastructure, targeting a near-doubling of annual output to more than two million tonnes globally by the mid-2030s. Chile sits at the heart of that plan. Beyond today’s Escondida clearance, the company submitted a US$5.9 billion environmental permit in March for a new concentrator to replace the ageing Los Colorados plant, and has filed a separate US$1.5 billion application to restart and expand the Cerro Colorado mine in northern Chile. Cumulatively, the pipeline signals a decisive tilt toward tier-one copper assets, underscored by the recent sale of BHP’s San Manuel property in Arizona to Faraday Copper.

Analyst View

The Street remains constructive despite today’s weakness. The consensus target price of A$61.67 implies material upside from current levels, reflecting analyst confidence in BHP’s long-term commodity positioning and the strategic value of its copper pipeline.

What happens next hinges on whether BHP can demonstrate capital discipline within its growth ambitions, and whether the commodity cycle cooperates. Any signs that the Escondida projects are tracking on time and budget, or that copper demand is accelerating, would validate the bull thesis and narrow the valuation gap. There will also be plenty of eyes on how things play out at Port Hedland, with the potential strike action likely to cast a shadow until a resolution is found either way.

BHP shares have now slipped firmly below the 50 day SMA at $60, a level that bulls were looking to hold as support. The intraday low for the share price also tested an earlier resistance level from back in April prior to the breakout, and that mid A$56 range could now be an important one to watch. The upcoming sessions could prove pivotal for momentum, with plenty of possible volatility on the cards.
