TETRA Technologies and Magrathea Metals Join Forces for U.S. Magnesium Production

TETRA Technologies and Magrathea Metals: A Partnership for Advancement in Magnesium Production

On December 2, 2025, TETRA Technologies, Inc. announced an exciting partnership with Magrathea Metals, Inc. aimed at revitalizing the domestic production of magnesium in the United States. The agreement, outlined through a term sheet, represents a significant step towards enhancing America's industrial capabilities and ensuring a secure supply of this critical mineral.

Magnesium is not just another metal; it is often referred to as the "gateway metal" due to its essential role in various industries, including defense. Recognized as a critical mineral by the Department of Energy, Department of War, and Department of the Interior, magnesium is pivotal for national security and economic stability. The collaboration seeks to establish a robust industrial base for magnesium production at TETRA’s Evergreen Project in Southwest Arkansas.

Advancements in Technology

Magrathea Metals is recognized for its innovative technology that allows for the extraction of clean and secure magnesium from seawater and brines. This partnership will leverage these advancements to manufacture magnesium in a sustainable and efficient manner. Alex Grant, the CEO of Magrathea, expressed enthusiasm about collaborating with TETRA, describing it as a vital step in transforming their innovative concepts into real-world industrial applications.

In addition to magnesium production, TETRA is also focused on developing a bromine production facility at the same site. Expected to yield 75 million pounds of bromine annually, this facility will be complemented by the production of lithium and other critical minerals, forming a multi-faceted resource operation that maximizes the utility of the site's brine resources.

The ONE TETRA 2030 Strategy

This initiative aligns with TETRA's broader ONE TETRA 2030 strategy, which aims to foster a secure domestic supply chain for critical minerals. Brady Murphy, the President and CEO of TETRA, highlighted the importance of this partnership, stating that it represents a significant advancement towards achieving their strategic goals while supporting national initiatives. TETRA's existing infrastructure and operational expertise, combined with Magrathea’s advanced manufacturing technology, are expected to create a transformative impact on the industry's future.

Support from the Government

The partnership also benefits from the backing of the U.S. government. Magrathea has secured funding through the Defense Production Act Title III to support the initial phases of the commercial project, further strengthening the collaboration's foundation. There are optimistic expectations for additional government backing as plans progress.

Local leaders, including Arkansas Governor Sarah Huckabee Sanders, have lauded this venture. The Governor emphasized the potential of Arkansas' communities to thrive in the competitive global landscape, presenting this investment as an opportunity to fortify the state's defense industry and promote innovation.

Future Implications

The partnership between TETRA and Magrathea Metals signifies a critical advancement in the quest for domestic magnesium production, a metal key to numerous industries and applications. With the demand for clean energy solutions and materials accelerating, securing a reliable supply chain is more vital than ever. The success of this undertaking could lead to a renewed focus on U.S. manufacturing capabilities and further investments in sustainable technologies, driving economic growth and enhancing national security. As both companies move forward, the implications of their collaboration will likely resonate throughout the industry for years to come.

This initiative not only embodies corporate collaboration but also reflects a broader commitment to sustainable practices and national resilience. The Evergreen Project is set to become a model for future industrial endeavors, highlighting how innovative partnerships can address pressing challenges while paving the way for sustainable development.
