UPDATE – 5E Advanced Materials Announces Successful Delivery of Step-Rate Testing Results

HESPERIA, Calif., Oct. 26, 2023 (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 (Fort Cady) Complex, today confirmed the submission of its Step-Rate Testing (“SRT”) results, to the Environmental Protection Agency (“EPA” or the “Agency”).  

Highlights:

• The fracture pressure gradient measured in the SRT was above the maximum operating pressure outlined in the Company’s Underground Injection Control (UIC) permit, meaning no design changes or permit modifications are needed
• 5E confirms all data and reporting associated with the successful completion of Step-Rate Testing under its permit conditions has now been submitted to the EPA
• EPA to review submission and provide final approval that will allow 5E to commence boron and lithium mining operations at the 5E Boron Americas Complex
• The Company has started final assembly of the production wellfield to allow the timely start of operations once EPA authorization is achieved

5E completed Step-Rate Testing on October 14, 2023, ahead of its planned schedule and delivered the test results to the EPA in accordance with the Agency’s approved protocols and is now awaiting a review of the results. The Company expects that upon completion of the Agency’s review, it will be granted official authorization to inject acid and therefore commence mining and plant operations at its 5E Boron Americas project.

“The expected results from the Step-Rate Test provide confidence that our planning and design work has demonstrated that our intended operations can perform safely and securely with respect to the extraction of boron and lithium from the wellfield. We look forward to the Agency’s completion of its review as we turn our focus now toward preparation for the commencement of operations,” said Chris Knight, VP of Operations at 5E Advanced Materials.
