Rio Tinto's $6.2 billion investment in Simandou, Guinea's iron ore treasure, signals a significant mining boom. The project aims to produce 60 million metric tons yearly, positioning Simandou as one of Earth's largest iron mines by 2025. However, the renewed iron rush, including the Nimba range project by High Power Exploration, raises concerns for Guinea's critically endangered western chimpanzees. With potential habitat disruption, conservationists fear adverse effects on the chimps, emphasizing the delicate balance between economic development and environmental conservation, reports Mongabay.


In the verdant landscapes of Guinea, a mining resurgence is underway, propelled by Rio Tinto's staggering $6.2 billion investment in Simandou. This ambitious project, slated to commence production in 2025, aims to extract a remarkable 60 million metric tons of high-grade iron ore annually. Simandou's significance lies not only in its economic potential but also in its promise to revolutionize green hydrogen-based steelmaking.

Simultaneously, the Nimba mountain range, home to the Société des Mines de Fer de Guinée (SMFG) project by High Power Exploration (HPX), is gearing up for iron mining after prolonged delays. As SMFG progresses with feasibility studies, it envisions transforming Guinea into a global exporter of high-quality iron ore.

However, amidst the excitement of economic prosperity, a shadow of concern looms over Guinea's critically endangered western chimpanzees. Conservationists express apprehension that the mining surge, particularly in the Nimba region, could jeopardize the habitat and well-being of these great apes.

The Nimba range harbors at least 136 western chimpanzees, residing near the Mount Nimba Strict Nature Reserve, a UNESCO World Heritage Site. The potential impact on these chimpanzees, coupled with habitat disturbances, poses challenges for their survival. A 2023 study published in Conservation Science and Practice emphasizes the potential threats, urging careful consideration of the ecological consequences.

As Simandou and Nimba become focal points of Guinea's economic development, concerns raised by conservationists cannot be ignored. Human Rights Watch and environmental groups emphasize the need for rigorous scrutiny, pointing to potential risks to local communities, environmental rights, and wildlife.

Christophe Boesch, founder of the Wild Chimpanzee Foundation, raises alarm over the rapid commencement of infrastructure work, highlighting the importance of meticulous planning to mitigate environmental impacts. While acknowledging the economic benefits, Boesch stresses the critical need to protect ecologically sensitive areas and implement measures for the coexistence of infrastructure and wildlife.

Jim Wormington from Human Rights Watch underscores community dissatisfaction with land acquisition processes, emphasizing the importance of ethical practices in the development of mining operations. As Guinea strives for economic growth through mining, the delicate balance between progress and conservation becomes paramount.


Guinea stands at a crossroads, poised for economic prosperity through its burgeoning mining ventures, notably the Simandou and Nimba projects. The colossal investments and potential for global prominence in iron ore production paint a promising picture. However, the fate of Guinea's critically endangered western chimpanzees hangs in the balance.
