Ontario, March 19 –Deep in northern Ontario, roughly 600 kilometres from Toronto, a construction project is unfolding that could fundamentally alter North America’s position in the global battery materials race.
Electra Battery Materials Corporation is building what is set to become the continent’s sole refinery capable of producing battery-grade cobalt sulfate — a compound without which modern lithium-ion batteries simply cannot be made.
On Wednesday, the Toronto-listed company issued a fresh construction update, confirming that the project is on schedule, within budget, and accelerating toward a commercial production target in the final quarter of 2027.
Why Cobalt Sulfate Matters
Cobalt sulfate is an unglamorous but indispensable ingredient in the cathodes of lithium-ion batteries that power electric vehicles, smartphones, and grid storage systems.
Despite its importance, the refining of cobalt into this usable form is almost entirely controlled by one country.
China currently accounts for more than 90% of global cobalt sulfate production — a dependency that has alarmed governments, automakers, and defence planners across the Western world.
Electra’s Ontario refinery is a direct response to that vulnerability. Designed to produce up to 6,500 tonnes of cobalt sulfate annually at full capacity, the facility would represent roughly 27% of world supply outside China once it reaches commercial scale.
Put simply, it would give North America something it does not currently have: a homegrown, allied-nation source for one of the EV era’s most strategically sensitive materials.
Construction Gains Momentum
Wednesday’s update painted a picture of steady, methodical progress. The company has moved well beyond detailed engineering and into active construction, with the majority of major mechanical and electrical equipment already delivered to the Temiskaming Shores site.
Fire suppression and instrumentation designs are complete, key process tanks are being installed, and roughly C$1.9 million in new equipment and installation contracts have been awarded in recent weeks.
Crucially, the early delivery of most major equipment means Electra has substantially reduced its exposure to supply chain disruptions — a lesson hard-learned by many industrial projects in the post-pandemic era.
The facility is a brownfield site with a significant head start. It previously hosted nickel and cobalt operations and already has substantial infrastructure in place, including utilities, process buildings, and site services.
During a construction pause in 2024, Electra used portions of the site to run a battery black mass recycling demonstration — a move that kept key process circuits active and validated critical systems ahead of the main production push.
Backed by Governments on Both Sides of the Border
The project’s strategic importance has translated into concrete financial support from multiple levels of government.
Total committed capital now exceeds the project’s approved construction budget, with approximately $48 million in non-dilutive funding secured from the U.S. Department of Defense, the Government of Canada, and Invest Ontario.
A further $34 million in equity financing, completed in October 2025, rounds out the funding package.
The involvement of the U.S. Department of Defense is particularly telling.
It signals that Washington views the facility not merely as a commercial enterprise, but as a critical piece of North American mineral security — especially relevant given ongoing trade tensions and the push to build resilient supply chains under frameworks like the Inflation Reduction Act and the broader critical minerals agenda.
LG Energy Solution Signed On as Anchor Customer
The commercial foundation of the project has also strengthened considerably. Earlier this month, Electra signed a binding term sheet with South Korean battery giant LG Energy Solution, locking in a firm commitment for 60% of the refinery’s cobalt sulfate production through 2029, with an option to extend the arrangement through 2032.
Speaking at the time of the agreement, CEO Trent Mell described LG Energy Solution as a “cornerstone customer” in Electra’s broader vision of a North American critical minerals supply chain.
The remaining 40% of production capacity is available for additional offtake customers, a space Electra is actively working to fill ahead of first production.
On the feedstock side, the company has supply arrangements in place with Glencore and other leading cobalt producers, ensuring raw material flows into the refinery once operations commence.
A Clear Path to 2027
The construction timeline is laid out in four distinct phases. Commissioning activities are expected to begin in the fourth quarter of 2026, with mechanical completion targeted for the second quarter of 2027.
Production ramp-up follows in the third quarter, and full commercial production is scheduled to begin before the end of 2027.
That calendar, if met, would mark a watershed moment for North American battery supply chains — the first time the continent has had a domestic, at-scale source of refined cobalt sulfate for battery manufacturing.
One Cloud on the Horizon
Not everything in Wednesday’s announcement was cause for celebration. Alongside its construction update, Electra disclosed that it received a compliance warning from the Nasdaq stock exchange on March 16, notifying the company that its share price has traded below the exchange’s minimum bid requirement of $1.00 for 30 consecutive business days.
The company has until September 14, 2026 to restore compliance and is evaluating its options.
The notice carries no immediate impact on trading or operations, and Electra’s shares continue to trade on both the Nasdaq Capital Market and the TSX Venture Exchange under the ticker ELBM.
Still, the disclosure is a reminder that even strategically vital projects are not immune to the pressures of public markets.
The Larger Race
Electra’s progress comes at a moment of acute urgency in the global battery materials landscape.
Industry analysts estimate that cobalt demand grew by nearly nine thousand metric tonnes in 2025 alone, with similar growth expected this year.
An increasing share of that demand is being steered away from Chinese suppliers by Western automakers and battery producers responding to policy incentives and supply chain diversification pressures.
The window for establishing non-Chinese production is open — but it will not stay open indefinitely.
If Electra delivers on its timeline, it will have secured a first-mover advantage that is unlikely to be easily replicated.
The refinery would stand as one of only two major facilities outside China capable of producing battery-grade cobalt sulfate at meaningful scale.
For a continent that has spent years talking about critical mineral sovereignty, the project in Temiskaming Shores is as close as North America has come to actually building it.
