The Metals Company Enters into MOU with Leading Nickel Processor PAMCO to Evaluate the Processing of Polymetallic Nodules into Battery Metal Feedstocks

16 March 2023
  • TMC and PAMCO have entered into a non-binding memorandum of understanding where PAMCO will evaluate the feasibility of processing of 1.3 million tonnes of wet polymetallic nodules (PMN) per year from 2025 onwards to produce lithium-ion battery and steel making feedstocks as part of TMC’s NORI-D Project Zero development
  • This MoU is a key element of TMC’s stated capital-light strategy to get into commercial production with low upfront capital costs by leveraging existing production assets which require minimal modification
  • PAMCO will undertake studies and testing on a 22-tonne PMN sample collected by NORI during the successful integrated collection system test completed on the NORI – D area in November 2022 to confirm the capacity and identify any additional facility requirements of the PAMCO Hachinohe facility to process PMN into nickel-copper-cobalt alloy and manganese silicate
  • PAMCO is also evaluating the feasibility of a new processing facility to convert nickel-copper-cobalt alloy into an upgraded matte product
  • The parties are working towards a binding MOU for toll-processing in 2023 with definitive agreements to follow

NEW YORK, March 16, 2023 (GLOBE NEWSWIRE) -- TMC The Metals Company (Nasdaq: TMC) (“TMC” or the “Company”), an explorer of the world’s largest estimated undeveloped source of critical battery metals, today announced that it has entered into a non-binding MOU with Pacific Metals Co Ltd (PAMCO) of Japan, to evaluate the toll treatment of an initial quantity of 1.3 million tonnes of wet polymetallic nodules per year at PAMCO’s Hachinohe smelting facility starting in 2025, consistent with the commencement of TMC’s planned first commercial production by end of 2024. The toll treatment is intended to take place on a dedicated rotary kiln-electric arc furnace (RKEF) processing line and produce two products: nickel-copper-cobalt alloy — an intermediate product used as feedstock to produce Li-ion battery cathodes — and a manganese silicate product used to make silico-manganese alloy, a critical input into steel manufacturing. PAMCO’s Hachinohe facility is located on the coast in northern Japan and is equipped with port and processing infrastructure required to receive and process polymetallic nodules and to ship products to customers.

Under the MOU, PAMCO will undertake studies to estimate the cost of processing polymetallic nodules through existing facilities and identify any additional equipment requirements, currently expected to be minimal. This work will inform expected nodule through-put, process operating conditions and product specifications for PAMCO’s dedicated production line. PAMCO has received a 22-tonne sample of polymetallic nodules for use in the evaluations.

In parallel, PAMCO is studying the addition of a facility to process the intermediate alloy to nickel-copper-cobalt matte, which is an upgraded intermediate battery supply chain feedstock. It is anticipated that the additional facility would be constructed once commercial processing of polymetallic nodules to alloy has been demonstrated. The parties are working towards a binding MOU for toll-processing in 2023 with definitive agreements to follow.

Gerard Barron, CEO & Chairman of The Metals Company, said: “We are excited about the prospect of working closely with PAMCO who have been smelting nickel laterite ores at their Hachinohe facility since 1965 and have considerable experience in adapting to various land-based feedstocks from the Pacific. Technically, the Hachinohe plant appears well-suited to deploy the near-zero solid waste flowsheet we developed for processing nodules with little modification. Strategically, we are aligned with PAMCO’s goal to contribute materials to a sustainable and recycling-oriented society. We look forward to working with PAMCO on the upcoming study program, finalizing the agreements and ultimately processing nodules to provide the metals required for the energy transition. This MoU is part of our stated capital-light strategy to get into initial commercial production swiftly and with lower upfront capital by re-using existing production assets like our first production vessel and former drill ship, Hidden Gem, and existing smelting facilities onshore, as well as by leveraging the deep operational expertise of our partners Allseas and onshore processors like PAMCO. These partnerships and our relentless focus on the environmental and social impacts of any future operations is how we unlock the enormous battery metal resource held by TMC.”

Masayuki Aoyama, PAMCO President, commented: “We look forward to working with TMC to enhance the value of the Hachinohe facility by processing a higher value material with a lower environmental impact. We are excited by the prospect of being the first commercial processor of polymetallic nodules and see the opportunity to emerge as supplier of Li–ion battery metals.”
