CALICHE DEVELOPMENT PARTNERS PUTS WORLD'S LARGEST HELIUM SALT CAVERN IN SERVICE WITH LONG-TERM LINDE CONTRACT

HOUSTON, July 30, 2025 /PRNewswire/ -- Caliche Development Partners announced today that it has begun providing helium storage service to Linde (Nasdaq: LIN), a leading global industrial gases and engineering company, at its Golden Triangle Storage (GTS) complex in Beaumont, TX.  The cavern is the third helium storage cavern in the world, the second in the US, and the world's largest at more than three billion cubic feet.  The Caliche team previously developed, operated, and sold the Coastal Caverns storage asset, which included North America's first helium cavern.  The new helium cavern brought in ~65 jobs during construction and has resulted in two full-time jobs. 

"With the help of our sponsor, Sixth Street, we are excited to put our third cavern at Golden Triangle Storage in service.  We believe the helium storage should have a lasting impact on the Beaumont-Port Arthur economy, and on vital industries like aerospace, electronics, healthcare and manufacturing," said Sam Wallace, Chief Commercial Officer of Caliche.
