Beyond building mines, railways and ports, Chinese companies involved in Guinea's Simandou iron ore project are investing in technology transfer and talent development to equip local workers with the skills to operate and manage one of Africa's largest mining and infrastructure projects.

Sophie Xiaohui Lyu, chief executive at project developer Winning Consortium Simandou, said the long-term success of the project, inaugurated in November, will depend not only on infrastructure investments but also on cultivating local talent capable of managing the project independently.

"The biggest resource is not what we mine, but what we cultivate," Lyu said.

Regarded as one of the world's largest untapped deposits of high-grade iron ore, the Simandou project includes a mine and a railway spanning more than 600 kilometers from southeastern Guinea to the Atlantic coast, making it one of Africa's largest rail infrastructure investments. The International Monetary Fund said the project could expand Guinea's GDP by more than one-fourth by 2030.

The project is being developed through a partnership involving the Guinean government, British-Australian mining company Rio Tinto, and Chinese companies including Baowu, Aluminum Corporation of China and Shandong Weiqiao Pioneering Group, with total investment exceeding $20 billion.
