Ivanhoe Mines has announced updated resource estimates for its Western Forelands exploration project in the Democratic Republic of Congo (DRC). The company, which holds between 45% and 100% of the permits covering this area, reports that the Makoko, Makoko West, and Kitoko deposits now total 8.38 million tonnes of copper in so-called "inferred" resources, almost double the volumes estimated in 2023.

These new estimates are based on 86,000 meters of drilling conducted between November 2023 and February 2025. Ivanhoe groups these three deposits under the name "district of Makoko," a 13 km-long area where copper occurs at depth, in geological formations similar to those mined at the nearby Kamoa-Kakula mine.

Overall, 494 million tonnes of ore at an average grade of 1.70% copper have been classified as inferred resources. This classification designates volumes whose presence is deemed probable, but not yet certified due to insufficient data. These resources offer strong potential but require additional drilling campaigns to be confirmed.

The district also includes 27.7 million tonnes of "indicated resources" at 2.79% copper, or 773,000 tonnes of metal. This category offers a more reliable estimate than inferred resources.

This exploration work is part of Ivanhoe's strategy to develop a second copper production center in the DRC. Faced with growing global demand driven by the energy transition, the company has been conducting an extensive prospecting campaign for several years in the Western Forelands region, adjacent to the Kamoa-Kakula mining complex.

The 2025 drilling program, with a budget of $50 million, includes over 100,000 meters of additional drilling. The results will enable a new resource update expected in 2026.

However, the publication of these figures does not mean that Ivanhoe will be opening a new mine in the short term. At this stage, the Makoko district remains an exploration project, still far from the feasibility, environmental study, and financing phases. However, its proximity to the existing Kamoa-Kakula infrastructure could facilitate future production. The company also points out that the area remains open to exploration, meaning that the potential identified could be further expanded in future campaigns.
