HESPERIA, Calif., April 29, 2024 (GLOBE NEWSWIRE) -- 5E Advanced Materials, Inc. (Nasdaq: FEAM) (ASX: 5EA) (“5E” or the “Company”), a boron and lithium company with U.S. government Critical Infrastructure designation for its 5E Boron Americas Complex, today announced the Company’s operations team has successfully achieved first production of boric acid and the Company amended its outstanding senior secured convertible notes to extend the waiver of the notes’ cash covenant.

First Production and Next Steps

With the first production batch of boric acid now achieved, 5E will continue to refine operating parameters to meet and exceed customer specifications. 5E anticipates beginning the customer qualification process with a variety of customer prospects. The customer qualification process will include 5E providing samples of boric acid for customers to validate their customer-established qualification criteria. Upon successful feedback from customers that the product meets their specifications, 5E will then deliver larger volumes of boric acid from the SSF, to the customer production facilities for product validation.
