    Copper at a crossroads

    Nyrstar’s Hobart zinc smelter.

    CRU’s World Copper Conference was run at the start of April 2025 in Santiago, Chile, with the industry facing a crossroads. The Americas account for nearly half of the world’s mined copper, with South America producing 38% and North America contributing 10%. However, North American copper mines face cash costs 51% above the global average and 79% higher than those of their South American neighbours, positioning the region as one of the most expensive copper-producing areas globally. These high costs create a significant challenge, especially as securing a reliable copper supply has emerged as a geopolitical priority.

    Compounding this issue, global copper demand is forecast to outstrip supply, with year-on-year deficits steadily increasing. In response, the United States and Canada have designated copper as a critical mineral essential for national security and supply chain resilience. To address this growing need, several major copper projects in North America hold the potential to boost regional output. In the US, notable tier 1 projects include Resolution, Pebble, and Mason, while in Canada, the Highland Valley Extension and Yellowhead projects hold the most promise. However, these projects are often stalled by prolonged regulatory delays and permitting obstacles.

    Mining projects in North America often take multiple decades to move from discovery to production. For example, the Resolution deposit, identified by Magma Copper Company in 1995, saw Rio Tinto and BHP form Resolution Copper Co. in 2004. Since then, the project has navigated a gruelling permitting process, its fate shifting with each US administration—most recently stalled by Biden in 2021. However, with President Trump’s early 2025 executive order to prioritise domestic critical minerals, Resolution’s ramp-up phase is likely to accelerate. Its prolonged timeline reflects a broader trend among North American mining projects.

    The global sulphur market has entered a holding pattern, as a wave of bearish sentiment has so far failed to move stubbornly high spot prices. The departure of a significant volume of product from the Middle East has emboldened buyers and shifted market sentiment firmly towards bearish, but at time of writing this has so far failed to translate into lower prices. With sellers in no hurry to lower prices and spot availability still tight, the market has stalled as both sides wait for the other to blink first.

    Restart for Hongda smelter

    Hongda's 100,000 t/a zinc smelter, in China's Sichuan Province, completed scheduled maintenance and equipment upgrading and officially resumed production on 21st June, the company said. The smelter had been shut down for planned maintenance since January, during which time a modernisation project for the electrolytic zinc smelting system was also carried out. Following the nearly six-month revamp, the resumption of production is expected to improve overall operational efficiency, reduce unit production costs, and increase the utilisation rate, The company said. The stable supply of sulphuric acid generated by the zinc smelter will effectively leverage the synergies of the "sulphur-phosphorus" industrial chain in the company, an help alleviate cost pressures on the company's phosphorus chemical business segment.
