Two Chinese manufacturers have taken over a Nigerian company that raised eyebrows in 2023 when it started building a lithium refinery in the country using a name that was very similar to one of the biggest and best-known Chinese producers.

A joint venture between Canmax Technologies Co. Ltd. and Jiangxi Jiuling Lithium Co. Ltd. last year took a controlling interest in Ganfeng Lithium Industry Ltd., a firm developing a lithium plant in the north of the West African nation, according to company documents obtained by Bloomberg.

Nigeria-registered Ganfeng was founded by Chinese businessmen in 2022, and created confusion a year later when it hosted a groundbreaking ceremony to kick off construction of the processing plant, which local authorities said will cost $250 million.

Shortly after the event, the company issued a statement to local media saying it had “no formal affiliation whatsoever” with Ganfeng Lithium Group Co. Ltd., one of the world’s biggest suppliers of lithium chemicals. A company representative offered no explanation as to why it was trading under a similar name.

Canmax and Jiuling’s takeover of the company — which corporate records show occurred in mid-2024 — brings financial clout and operating nous to the development of Nigeria’s nascent lithium industry, which has typically shipped raw ore to China for further treatment.

The investments signal that Chinese lithium companies are doubling down on efforts to lock down feedstock in anticipation of soaring future demand for the metal used in electric-vehicle batteries. They’ve been investing heavily in Africa’s lithium deposits from Mali to Zimbabwe, even after prices tumbled almost 90% from a peak in 2022.

Separately, Canmax also announced this month that it will invest over $200 million to develop two lithium mining deposits elsewhere in northern Nigeria, working with local company Three Crown Mines Ltd.

Shenzhen-listed Canmax is a large producer of lithium chemicals whose founder, Pei Zhenhua, made his fortune as an investor in Contemporary Amperex Technology Co Ltd., the world’s top EV battery maker. Pei and CATL co-own a separate lithium mining and processing joint venture. Jiuling is a chemical producer based in Jiangxi – one of China’s lithium mining hubs – and a supplier to CATL.

Nigeria has sizable untapped deposits of metals including gold, tin and lithium, but most extraction is done informally by so-called artisanal miners on a small-scale or manual basis.

The Nigerian Ganfeng signed an agreement in September allowing the company to mine lithium for 10 years under permits held by a firm owned by the government of Nasarawa state – the location of the plant under construction.

The first phase of the facility is due for completion by the middle of this year and the second phase four months later, said Ibrahim Abdullahi, the chief executive officer of the state’s development and investment agency. “Nasarawa state is pleased with this investment and welcomes more of it,” he said.

Canmax and Jiuling, which together own 75% of the Nigerian Ganfeng, declined to comment. Nigeria’s federal mines ministry didn’t respond to questions about the acquisition or how much lithium concentrate it will produce.
