Critical minerals have become a central focus of industrial and national security strategies across North America. Governments and industry have invested heavily in securing access to raw materials, recognizing that minerals such as cobalt are essential to advanced manufacturing, defense technologies, and energy storage.

But securing access to cobalt ore is only one piece of the puzzle. Before cobalt can be used in lithium-ion batteries, aerospace components, or defense applications, it must be refined into high-purity products. This critical step is the midstream supply chain which remains one of North America's greatest vulnerabilities.

Mining Alone Doesn't Create Supply Chain Security

Over the past several years, significant progress has been made in developing and securing upstream sources of critical minerals. New mining projects, strategic partnerships, and investments have expanded access to cobalt resources across North America and allied nations.

Yet mining is only the first step in the value chain. Extracting cobalt from the ground does not guarantee manufacturers have access to the battery-grade materials needed to produce advanced technologies. A resilient supply chain depends on every stage of the process, from mining and refining to battery manufacturing working together.

As demand for critical minerals continues to grow, attention is increasingly shifting beyond resource development to the infrastructure required to transform raw materials into usable products.

Why Cobalt Matters to Modern Defense

Cobalt plays an important role in some of today's most advanced defense technologies.

In lithium-ion batteries, cobalt contributes to energy density, thermal stability, and safety, characteristics that are essential for systems operating in demanding environments. These batteries power a growing range of applications, including unmanned aerial systems, autonomous vehicles, portable military equipment, and communications infrastructure.

Beyond batteries, cobalt is a critical component in high-performance superalloys used in jet engines, gas turbines, missile systems, and other aerospace applications where materials must withstand extreme temperatures and mechanical stress.

As defense platforms become increasingly electrified and technologically advanced, demand for reliable sources of battery materials and specialty metals is expected to grow alongside them.

Refining Is the Missing Middle

While mining often receives the greatest attention, refining is the step that connects raw materials to manufacturers.

Today, the majority of the world's battery-grade cobalt refining capacity is concentrated in China, leaving North American manufacturers reliant on overseas processing. This concentration creates a structural challenge for companies seeking to establish regional battery supply chains. Automotive manufacturers, battery producers, and defense contractors all require reliable access to refined materials not simply mined resources.

Developing refining capacity closer to end markets can help shorten supply chains, improve transparency, reduce transportation risks, and strengthen the resilience of critical manufacturing sectors.

Building a More Integrated North American Supply Chain

Strengthening North America's critical minerals ecosystem requires investment across the entire value chain ranging from responsible resource development to refining, recycling, and advanced manufacturing.

Electra is helping address one of the most significant gaps in that chain through the development of North America's first battery-grade cobalt sulfate refinery. Once operational, the refinery will provide domestic processing capacity capable of converting cobalt feedstock into battery-grade material for North American customers.

Looking Ahead

The conversation around critical minerals is evolving. It is no longer enough to ask where materials are mined. Increasingly, the focus is shifting to where they are refined, processed, and manufactured into products that support critical industries.

Closing the midstream gap will be essential to building a more secure and competitive North American battery materials ecosystem. As demand for advanced batteries and defense technologies continues to grow, refining capacity will play an increasingly important role in ensuring that critical minerals can move efficiently from resource to finished product.
