Glencore Expands Copper Resources Amid Merger Talks with Rio Tinto

Glencore has announced significant increases in its copper reserves, enhancing its leverage in ongoing negotiations to merge with Rio Tinto. The FTSE 100 commodities trader has revealed a more optimistic outlook for its copper assets, bolstering its position in a competitive market characterized by rising demand for the metal.

The company’s estimates indicate that its total mineral resource at the New Range project in Minnesota has increased by 28 percent, amounting to 1.7 billion tonnes of ore. This revision comes as a result of updated cost and economic assumptions, making it economically viable to extract more resources. Simultaneously, higher copper prices are enabling Glencore to reassess its mineral assets more favourably.

In Peru, the Coroccohuayco project witnessed an increase of 301 million tonnes, driven largely by new reinterpretations and modelling of previous data. New drilling results also contributed to a net gain of 116 million tonnes at the Antapaccay site, thanks to both revised economic assumptions and the rise in copper and gold prices.

Glencore’s advances are noteworthy, particularly evident in the Lomas Bayas mine in Chile, where there was a net gain of 641 million tonnes following promising new drilling discoveries. Additionally, at the El Pachón project in Argentina, there was a notable increase of 650 million tonnes, reflecting the impact of 18 new drill holes exercising deeper evaluation of the ore body.

The company’s production report for 2025 showed that it met guidance targets for most key commodities, except cobalt. Expectations for copper production exceeded market predictions by 3 percent, an achievement praised by analysts. Ben Davis, an analyst at RBC Capital Markets, remarked that Glencore’s performance aligns well with the current market dynamics.

As geopolitical tensions and trade disruptions drive copper prices to record highs, Glencore’s robust performance in this sector positions it favourably for potential mergers or acquisitions. The forthcoming negotiations with Rio Tinto could reshape the landscape of the mining industry, positioning the united entity as a leading global player.
