A partly built refinery in northeastern Ontario has become a test of whether North America can turn critical-minerals policy into actual industrial capacity. Electra Battery Materials is pushing ahead with its cobalt sulfate refinery in Temiskaming Shores after securing support from both Canada and the United States, while simultaneously studying a much larger nickel-processing opportunity in the southeastern U.S. The strategy reflects a wider shift in economic and defence policy: governments increasingly see refining—not simply mining—as a strategic weakness. Electra’s Ontario project is scheduled to move through commissioning and production ramp-up in 2027, while its proposed American nickel facility remains at the engineering-study stage. Together, the projects illustrate how Canada-U.S. critical-mineral cooperation is evolving from resource development toward the harder task of building the processing infrastructure between mines, recycled batteries and manufacturers.

Allied Governments Are Putting Real Money Behind the Ontario Refinery

Electra’s Ontario refinery has attracted an unusual combination of Canadian and American government support because the project sits at the intersection of automotive manufacturing, battery production and defence supply chains. In May 2026, the Canadian government announced a $20-million Strategic Response Fund investment toward Electra’s roughly $99.4-million refinery project in Temiskaming Shores. That commitment followed earlier federal assistance tied to refinery development and battery recycling. Ontario has also supported the financing plan, with Electra previously announcing a C$17.5-million proposed contribution from Invest Ontario. For a relatively small mining-and-processing company, government participation has become a critical part of moving the brownfield facility toward completion.

Washington’s participation is particularly notable because the refinery is located in Canada. The U.S. Department of Defense awarded Electra US$20 million in August 2024 through the Defense Production Act Investments program to help complete the hydrometallurgical plant. The Pentagon specifically linked the project to production of cobalt sulfate for large-capacity batteries used in commercial and defence applications. Electra said in February 2026 that approximately US$48 million of its refinery financing package consisted of government grants and loans from the United States, Canada and Ontario. The cross-border support demonstrates how critical-mineral infrastructure is increasingly being treated as continental rather than strictly national.

Construction Has Moved From Financing Problems to an Execution Test

Electra’s biggest challenge is no longer simply finding enough money to restart construction. Its board approved a US$73-million, or approximately C$100-million, remaining construction budget in February 2026, while the company reported roughly US$82 million in aggregate financial support for construction. That included government funding and US$34 million of equity financing completed in October 2025. Major equipment had already been procured and long-lead items delivered, reducing one source of project risk. By the spring of 2026, Electra was awarding significant construction packages, including work on solvent extraction and structural, mechanical and piping systems.

The timeline is ambitious but clearly defined. Electra expects early commissioning of selected utilities and circuits to begin in the fourth quarter of 2026, followed by mechanical completion in the second quarter of 2027. Production ramp-up is targeted for the third quarter, with commercial production planned for the fourth quarter of 2027. The company has separately estimated approximately US$15 million in costs related to commissioning, ramp-up, initial working capital and operational readiness beyond mechanical completion. Those milestones matter because Electra has experienced delays and financing challenges before. Government backing reduces financing risk, but it does not eliminate the practical difficulty of completing, commissioning and steadily operating a sophisticated hydrometallurgical refinery.

The Ontario Plant Would Fill a Missing Link Between Mining and Batteries

The Temiskaming Shores refinery is designed to do something that remains scarce in North America: convert cobalt-bearing feedstock into battery-grade cobalt sulfate suitable for downstream manufacturers. Electra plans to begin with annual production of approximately 5,120 tonnes of contained cobalt, with its crystallizer circuit capable of supporting production of as much as 6,500 tonnes annually after optimization. At full capacity, the Canadian government and Electra estimate that output could supply the cobalt sulfate needed for batteries equivalent to as many as one million electric vehicles per year.

That distinction between extracting minerals and refining them is central to the project’s strategic importance. Canada already has a substantial mining sector, but the federal Critical Minerals Strategy has repeatedly identified midstream processing and refining as an area requiring additional investment. As of March 2025, Canada counted 56 active mines producing critical minerals and 31 critical-mineral processing facilities, alongside 171 advanced projects. The sector contributed an estimated $40 billion directly and indirectly to Canadian GDP in 2023 and supported roughly 110,000 jobs. Electra’s refinery is therefore not simply another mining development. It is an attempt to capture more of the value-added work that traditionally occurs after raw or intermediate mineral products leave the mine gate.

Cobalt’s Strategic Importance Extends Well Beyond Electric Cars

Cobalt is frequently discussed as an electric-vehicle material, but its strategic uses explain why a U.S. defence agency was prepared to finance processing capacity in Ontario. The U.S. Geological Survey lists rechargeable battery electrodes as the world’s leading cobalt application while also pointing to superalloys used in gas-turbine engines, corrosion-resistant materials, magnets, cutting tools and other industrial applications. The Pentagon said its Electra award was intended to strengthen the industrial base serving both defence and commercial markets, describing cobalt sulfate as an important precursor for large-capacity batteries used in numerous defence systems.

Supply concentration adds another layer of urgency. Canada’s Critical Minerals Strategy has highlighted the high concentration of critical-mineral processing in China, estimating in its 2024 annual report that China processed roughly 60% to 70% of the world’s lithium and cobalt. Electra has cited more recent industry data suggesting China accounts for more than 90% of global cobalt sulfate supply specifically. Those figures measure somewhat different parts of the market, but both point in the same direction: mining a mineral does not guarantee control over the finished material manufacturers actually need. A refinery in Ontario gives allied manufacturers another processing option and helps explain why Ottawa and Washington are willing to share some of the cost.

LG Energy Solution Gives Electra a Customer Before Production Starts

A refinery also needs buyers, and Electra has spent years building a commercial relationship with South Korea’s LG Energy Solution. In March 2026, the companies announced an updated binding term sheet covering cobalt sulfate from the Ontario refinery. Under the revised arrangement, LG Energy Solution has a firm commitment covering 60% of Electra’s production through 2029, with an option that could extend the relationship through 2032. Leaving roughly 40% of expected capacity uncommitted gives Electra room to pursue additional customers or respond to future changes in cobalt pricing.

The arrangement is important because new mineral-processing facilities often face a financing problem: lenders and investors want evidence of future demand before construction is finished, while customers want evidence that a plant can actually deliver material at the necessary purity and scale. Electra is trying to bridge that gap with a major battery manufacturer already attached to the project. On the feedstock side, the company has commercial arrangements involving suppliers including Glencore and Eurasian Resources Group and has also tested material from North American sources. That includes its Iron Creek cobalt-copper assets in Idaho and material associated with Ontario’s historic Cobalt Camp, part of a longer-term effort to diversify where its refinery gets cobalt.

Electra’s Next Big Idea Is a Nickel Refinery in the Southeastern U.S.

While Ontario remains Electra’s immediate construction priority, the company is already investigating what could become its next major processing facility. In June 2026, Electra disclosed that it had hired engineering consultants to advance a development study for a potential battery-grade nickel refinery in the southeastern United States. The concept being evaluated is considerably larger in tonnage than the Ontario cobalt operation: approximately 15,000 tonnes per year of nickel sulfate and nickel metal, together with around 1,000 tonnes annually of cobalt metal.

No final investment decision has been made, and the company has not publicly identified a specific site. The engineering work is meant to determine capital requirements, operating parameters, development schedules and site-selection criteria before Electra decides whether more detailed engineering is justified. The company said it has narrowed the search to a preferred region based on infrastructure, logistics, workforce availability and potential supply-chain partners. It is also looking at proximity to deep-water ports and the expanding battery-manufacturing corridor in the southeastern United States. That makes the project a strategic study rather than a committed plant, an important distinction when assessing how quickly new U.S. nickel-processing capacity could actually emerge.

Imported Nickel Feedstock Could Be Refined Closer to American Customers

Electra’s proposed U.S. facility does not depend on waiting for enough new American nickel mines to open. The study is examining a refinery that initially could process globally sourced mixed hydroxide precipitate, known as MHP, and mixed sulfide precipitate, or MSP. These intermediate materials contain nickel and other valuable metals and can be shipped to a hydrometallurgical facility for further refining. Electra says the approach would allow processing capacity to be established sooner while North American mining and recycling supply develops over time.

That strategy reflects a broader government focus on the processing stage of the supply chain. The U.S. Department of Energy announced a funding opportunity of up to US$500 million in March 2026 aimed at expanding domestic critical-material processing, battery manufacturing and recycling capacity. DOE identifies high-purity nickel and cobalt as important energy-storage materials and has repeatedly emphasized the vulnerability created by insufficient domestic processing. Electra’s proposal fits that policy direction: bring intermediate mineral material into the United States, refine it near customers, and gradually substitute more locally sourced mine or recycled feedstock where economics permit. It would not make the U.S. completely resource-independent, but it could move a strategically important stage of production onto American soil.

A New U.S. Black-Mass Rule Could Strengthen the Recycling Economics

A policy change announced in August 2026 may add another potential feedstock source. The U.S. Bureau of Industry and Security published a temporary rule requiring U.S. sellers of battery black mass to allocate 100% of covered monthly sales to U.S. persons beginning August 27, 2026, unless an adjustment or exception is granted. Black mass is the shredded material recovered from lithium-ion batteries and can contain nickel, cobalt, lithium, manganese, graphite and other valuable components. The rule is scheduled to remain in effect for one year unless modified or extended.

Electra argues that keeping more black mass inside the United States could improve feedstock availability for domestic refiners. Its proposed nickel refinery is being designed primarily around MHP and MSP, but the company says recycled battery material could supplement those sources over time. Electra already operated a plant-scale recycling demonstration at its Ontario complex and reported recovery of lithium, nickel and cobalt from black mass. The important caveat is timing: the American refining project still needs engineering, site selection, financing, permitting and a final construction decision. The new rule may improve its strategic case, but it does not by itself create the refining capacity needed to process the retained material.

Ontario Comes First, and the U.S. Expansion Still Has to Earn Its Way Forward

Electra’s two-project strategy highlights both the opportunity and the difficulty facing North America’s critical-mineral industry. In Ontario, much of the early de-risking has already occurred. The refinery is a permitted brownfield project, government funding has been assembled, major construction contracts are being awarded, equipment is on site and a cornerstone customer has committed to taking a significant portion of production. Yet commercial output remains targeted for late 2027, meaning construction, commissioning and ramp-up still have to perform close to plan before the facility can prove its economics.

The American nickel project sits much earlier on the development curve. Its proposed production capacity is substantial, and current U.S. policy increasingly favours domestic refining and recycling, but Electra has not yet committed to build it. Capital cost, feedstock pricing, customer agreements, site incentives, permitting requirements and long-term government policy will all influence the final decision. That is what makes the Ontario refinery especially consequential. If Electra can turn government support and years of preparation into reliable cobalt production, it gains operating experience and credibility for a broader North American refining platform. If execution slips substantially, the case for immediately taking on a second major refinery becomes more difficult.
