Two industry heavyweights are doubling down on their presence in South America with a massive investment aimed at boosting metal supplies. Polish mining giant KGHM and Australia’s South32 have unveiled plans to spend 725 million dollars expanding the Sierra Gorda copper and molybdenum mine in northern Chile. The ambitious move is designed to ramp up annual copper production by twenty percent, pushing the facility’s processing capacity from 48 million tons of ore up to 60 million tons each year.
The project is expected to reach completion by late 2029, with full commercial output hitting its stride in the latter half of 2030. To keep costs low and sustainability high, the partners plan to optimize their existing infrastructure, utilizing a seawater pipeline and relying entirely on renewable energy sources for electricity. This strategic upgrade comes at a time when traditional mines across South America are seeing declining ore grades, making efficiency gains critical for maintaining profitability.
Beyond just increasing current volume, the companies are looking toward the distant future through aggressive exploration in the nearby Catabela Northeast zone. Initial drilling suggests there may be billions of tons of mineral resources waiting to be tapped, which could potentially extend the lifespan of the mine for decades. For KGHM, this expansion reinforces its status as Europe’s leading copper producer and diversifies its portfolio away from domestic borders.
Meanwhile, for South32, the move fits into a broader trend of streamlining its global operations. The Australian firm has recently shed various aluminum and coal assets as part of a larger corporate pivot toward higher growth opportunities. By investing heavily in Chile alongside KGHM, both firms are positioning themselves to capitalize on an increasingly tight global copper market driven by the worldwide transition toward green technology.
