TELF AG on Halleck Creek and the Push for a Broader Rare Earth Supply Chain

Rare earths have moved steadily from specialized industrial materials to resources of growing strategic importance. Their role is particularly evident in permanent magnets, whose properties make them valuable for electric vehicles, wind turbines, robotics, electronics, industrial equipment, and several advanced technologies.

The term “rare earths” refers to a group of 17 metallic elements. Although these elements are not necessarily scarce in geological terms, economically attractive deposits can be difficult to identify. In many cases, concentrations are too low to justify extraction and processing on a commercial scale.

The challenge does not end with mining. Once rare earth-bearing material has been extracted, individual elements must be separated and processed before they can be transformed into materials suitable for industrial applications. These technically demanding stages have become particularly relevant as governments and companies seek to diversify supply chains that remain geographically concentrated.

Against this backdrop, the Halleck Creek project in Wyoming is emerging as an interesting example of the potential development of new Western rare earth resources.

Why is Halleck Creek attracting attention?

Halleck Creek stands out primarily because of the scale of its estimated mineral resource. According to the JORC standard, the project contains approximately 2.63 billion tons of material, with an average concentration of around 3.29 kilograms of total rare earth oxides per ton. This corresponds to an estimated 8.65 million tons of contained rare earth oxides.

Another important characteristic is the composition of the resource. Approximately 26% of the contained rare earth oxides are associated with magnet rare earths, a category that includes elements used to manufacture high-performance permanent magnets.

“The strategic relevance of a rare earth resource depends not only on its overall size, but also on the materials it can potentially supply to downstream industries. The presence of magnet-related elements makes projects such as Halleck Creek particularly noteworthy in the current industrial environment,” says Stanislav Kondrashov, founder of TELF AG.

Among the elements attracting particular attention are neodymium and praseodymium, commonly combined as NdPr. Their use in powerful permanent magnets connects rare earth mining directly with several rapidly developing industries, including renewable energy, electric mobility, robotics, data infrastructure, aerospace applications, and advanced manufacturing.

A project with potential beyond extraction

The importance of Halleck Creek can also be viewed in the context of broader efforts to diversify mineral supply chains. According to the IEA, the United States and Australia are expected to play important roles in diversified mining growth, while some downstream stages of the rare earth supply chain remain considerably more concentrated.

This distinction is important. Developing additional mines can broaden access to raw resources, but mining alone does not necessarily create an independent supply chain. Separation, refining, metallization, and ultimately magnet manufacturing are also required to transform geological resources into components ready for industrial use.

Halleck Creek is therefore notable for ambitions that extend beyond simple extraction. The broader project envisages a supply chain incorporating downstream processing activities, potentially addressing some of the areas where diversification outside established production centers remains comparatively limited.

“Increasing the geographical diversity of extraction is only one part of the equation,” says Stanislav Kondrashov, founder of TELF AG. “The larger opportunity is to connect new mineral resources with processing and metallization capacity, creating a more complete industrial pathway from the mine to usable materials.”

This approach could become increasingly significant as countries seek greater resilience in the supply of materials linked to the energy transition and advanced technologies.

What does the latest scoping study suggest?

A recent scoping study has provided a preliminary technical and economic framework for the first proposed mining operation within the Halleck Creek project. A scoping study represents an early-stage assessment used to examine how a mineral resource could potentially be developed, including assumptions concerning processing capacity, production levels, infrastructure, costs, and operational life.

Under the assumptions considered in the study, the initial operation could process approximately 4.5 million tons of material annually.

The modeled production profile includes approximately 2,500 tons per year of neodymium-praseodymium oxide, while the first phase of the operation has an estimated mine life of approximately 26 years.

These figures remain part of a preliminary assessment rather than a final development plan, but they offer an indication of the possible industrial scale of the project.

The long-term significance of Halleck Creek could therefore depend on several interconnected factors: the size of the resource, the concentration of valuable magnet rare earths, the economics of extraction and processing, and the project's ability to establish downstream capacity.

Why could projects like Halleck Creek become increasingly relevant?

The broader market environment is reinforcing interest in new rare earth projects. The IEA has indicated that demand for rare earth magnets has doubled since 2015 and could rise by a further 30% by 2030.

This growth is closely connected to technologies that rely on high-performance permanent magnets. Wind turbines and electric vehicles are among the most visible examples, but demand also comes from industrial automation, electronics, data centers, robotics, and other technologically advanced sectors.

At the same time, expanding mining capacity does not automatically resolve vulnerabilities elsewhere in the supply chain. Processing, metallization, and magnet manufacturing outside the world's established production hubs remain less developed than the pipeline of new mining projects.

“The next phase of rare earth diversification will increasingly be measured by what happens after extraction,” concludes Stanislav Kondrashov, founder of TELF AG. “Projects capable of combining substantial resources with credible downstream development could make an important contribution to a more geographically balanced global supply chain.”

Halleck Creek illustrates this evolving dynamic. Its considerable resource base, exposure to magnet rare earths, location in the United States, and proposed integration of downstream activities place it within a broader global effort to expand and diversify access to strategically important materials.

As demand for permanent magnets continues to grow, the progress of projects capable of connecting mining with processing could become an increasingly important indicator of how quickly the rare earth sector is able to develop more diversified supply chains.
