HOUSTON, Dec. 20, 2022 (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 (“Small Scale Facility”), is pleased to confirm it continues to target production of boron and lithium by the end of CQ2 2023 from its flagship project in Southern California.

5E Boron Americas (Fort Cady) Complex

The initial phase of construction activities continue on schedule at the Company’s Fort Cady Complex, which will see it become the first producer of boron this century, and the next U.S.-based lithium producer.

Key dates associated with initial production are:

1. Pre-commissioning activities to commence before December 31, 2022
2. Facility commissioning to conclude prior to the end of CQ1 2023
3. Initial production of boric acid to commence by the end of CQ1 2023
4. Initial production of lithium to commence by the end of CQ2 2023

Value Considerations for 5E Boron Americas (Fort Cady) Large-Scale Complex
The Company is considering multiple options for the delivery of its 5E Boron Americas (Fort Cady) Large-Scale Complex to take advantage of the growing and expected positive surge in market conditions. Boron and lithium markets are experiencing significant demand, causing supply constraints, which is being driven by global government and OEM initiatives for faster adoption of decarbonization technologies. As a result, 5E is currently assessing a number of options to position the Company appropriately for future full production operations:

1. Focus on fast tracking initial large-scale production as soon as possible by leveraging engineering work already completed as a part of the eDFS (refer ASX release April 16, 2020) coupled with real operating data obtained from initial Facility production
2. Optimize planned product output to achieve best possible returns across boron advanced materials categories
3. Optimize production modules based on customer demand, financing, and Facility capacity

CEO Recruitment Process

The Board continues to progress the recruitment process for a new CEO and is pleased with the caliber of candidates under consideration, with the aim to announce an appointment as quickly as possible.
