(Reuters) - General Motors Co and South Korea's POSCO Future M said on Friday they will invest more to boost production at their chemical battery materials facility in Canada, taking their estimated total investment in the plant to over $1 billion.
The companies said the new investment includes an additional CAM and a precursor facility for local on-site processing of critical minerals.
The development comes a few days after the Canada's federal government and the Quebec province each provided about C$150 million ($112 million) for the facility.
The companies last year established Ultium CAM joint venture, which is majority owned by POSCO Future M, and had initially invested about $327 million, according to media reports.
Their battery facility in Becancour, Quebec, will produce cathode active material (CAM) for electric vehicle (EV) batteries.
