FEAM

5E Advanced Materials, Inc. (Nasdaq:FEAM) (ASX:5EA) (“5E” or the “Company”) has broken ground and commenced construction activities on its Small-Scale Boron Facility (“SSBF”) with a leading U.S. publicly traded full-service contractor. The SSBF is scheduled to enter service in Q4 2022 and represents the first new U.S. based source of boron in more than 50 years.

Production from the SSBF will be used to advance customer contracts for boron advanced materials, optimize engineering and construction for 5E’s large-scale boron and lithium facility, and generate sales. The SSBF will also create jobs in an economically distressed Opportunity Zone in Southern California and further position 5E for U.S. government support as a future producer of critical materials.

Securing a reliable and sustainable supply of critical materials has become a key focus of the U.S. government given reliance on at risk international supply and escalating geopolitical tensions. The Presidential Executive Order issued in February 2022 and ensuing Memorandum on Presidential Determination released in March 2022 highlight the White House’s support for facilities such as the SSBF. See the below excerpt from the Presidential Determination.

“The United States depends on unreliable foreign sources for many of the strategic and critical materials necessary for the clean energy transition… Demand for such materials is projected to increase exponentially as the world transitions to a clean energy economy. To promote the national defense, the United States must secure a reliable and sustainable supply of such strategic and critical materials.”

Commenting on the commencement of SSBF construction, CEO, Mr Henri Tausch noted:

“We are pleased to progress our SSBF, which targets first production of boron later this year. Initial production will serve as a major catalyst for the Company since it will advance our boron advanced materials business and optimize engineering for our large-scale boron and lithium facility.

The SSBF and proceeding large-scale production will also bolster America's supply chains as it will provide a new domestic source of critical materials that focus on national security, clean energy, and future facing applications.”
