VANCOUVER, BC / ACCESS Newswire / March 16, 2026 / CoTec Holdings Corp. (TSX-V:CTH)(OTCQB:CTHCF) ("CoTec" or the "Company") is pleased to note Friday's press release by HyProMag USA LLC ("HyProMag USA"), its U.S.-based joint venture rare earth permanent magnet recycling and manufacturing company.

HyProMag USA hosted a commissioning event for the Inserma hard disk drive magnet separation system installed at the ILS facility in Williston, South Carolina ("Williston Site") on Friday, March 13, 2026.

The commissioning marks an operational milestone in HyProMag USA's growing U.S. rare earth magnet recycling platform and represents the first stage of feedstock preparation supporting the Company's broader "hub-and-spoke" manufacturing strategy. Under this model, magnet-bearing materials are recovered and pre-processed at regional facilities such as the Williston Site before being supplied to HyProMag USA's planned rare earth magnet recycling and manufacturing hub in Dallas-Fort Worth, Texas.

The commissioning event was attended by federal, state and regional leaders who highlighted the importance of expanding domestic capabilities in critical materials and advanced manufacturing.

"This investment demonstrates how South Carolina continues to attract innovative companies to build the technologies that will power the next generation of American manufacturing - creating jobs," said Congressman Joe Wilson. "Rare earth minerals are critical to our national security, and we must take control of our domestic manufacturing and supply chains to protect American interests."

"We're grateful to Congressman Wilson and the many state and local South Carolina leaders who joined us to mark this important milestone," said Julian Treger, CEO of CoTec Holdings Corp. "Partnership and community support are essential as we work to establish a new domestic platform for rare earth magnet recycling and manufacturing in the United States. Through collaborations with companies like ILS and strong engagement with local stakeholders, HyProMag USA is building the feedstock supply chains and operational capabilities needed to support large-scale magnet production in the years ahead."
