EVelution Mitsui Cobalt Offtake Agreement Anchors Arizona Processing Project

EVolution, Mitsui

EVelution Mitsui cobalt offtake agreement gives the nascent US cobalt processor a major commercial anchor for its planned Arizona facility. EVelution Energy has signed a binding deal to supply Japanese trading firm Mitsui with the substantial majority of future cobalt metal output from the project.

The EVelution Mitsui cobalt offtake agreement covers up to 3,000 t/yr of cobalt over five years. The contract is valued at about $850mn based on current market prices, according to the company.

The EVelution Mitsui cobalt offtake agreement is strategically important because the US is trying to build more domestic processing capacity for battery and defence-related materials. Cobalt remains essential for electric vehicle batteries, superalloys, industrial chemicals and high-performance manufacturing.

The planned facility in Yuma County, Arizona, is expected to begin construction in early 2027. EVelution aims to complete the cobalt processing plant in 2029.

Binding Offtake Improves Project Bankability

The Mitsui agreement gives EVelution a clearer demand base before construction begins. For a new cobalt processor, a binding offtake agreement can improve financing prospects by showing that future output already has a committed buyer.

This matters because processing projects require large upfront capital, technical qualification and long commissioning timelines. Buyers also need confidence that the producer can deliver metal consistently to specification.

Mitsui’s role adds strategic weight. Japanese trading houses often connect raw materials, processing assets and downstream manufacturers through long-term supply agreements.

The deal also strengthens Japan’s access to non-China cobalt metal. Japan has major battery, electronics, automotive and industrial materials sectors, and secure cobalt supply remains important for several high-value manufacturing chains.

For EVelution, the agreement supports a route into the market before commercial production starts. It also helps position the Arizona facility as part of a wider allied supply-chain network rather than only a domestic US project.

US Cobalt Processing Remains a Strategic Gap

The Arizona project addresses a key weakness in the US critical minerals chain. The country needs more domestic and allied refining capacity for materials that support batteries, aerospace, defence, chemicals and advanced manufacturing.

Cobalt supply is globally concentrated, with mining and processing exposed to geopolitical, environmental and trade risks. Building US processing capacity can reduce dependence on external refining routes and improve supply security for manufacturers.

The facility’s planned output of up to 3,000 t/yr under the Mitsui agreement would not transform the global cobalt market alone. However, it could provide an important domestic source of cobalt metal for customers seeking traceable and secure supply.

Cobalt’s end-use profile also makes the project strategically relevant. Battery demand remains important, but superalloys and industrial chemicals give cobalt a broader role across aerospace, energy, defence and manufacturing.

The key challenge will be execution. EVelution must move from offtake signing to financing, permitting, construction, commissioning and qualification. Each step will determine whether the project can become a reliable part of the US cobalt supply chain.

The Metalnomist Commentary

The Mitsui deal shows that critical minerals projects increasingly need customer commitments before they can become bankable. For US cobalt, the strategic question is no longer only resource access, but whether domestic processing projects can reach commercial scale on time.
