 during January 2024 we selected Fluor Corporation (“Fluor”) as our Engineering, Procurement and Construction Management Firm (“EPC”) service provider to lead our FEL-2 engineering program. During August 2025, Fluor completed the FEL-2 engineering for our proposed commercial scale facility, which culminated in the issuance of a S-K 1300 compliant Preliminary Feasibility Study (the “PFS”). The PFS included a capital estimate of approximately $435 million to construct the proposed commercial-scale facility capable of producing 130,000 short tons of boric acid per annum, inclusive of $55 million for contingency and approximately $13 million of owner’s costs, and resulted in approximately 41% of the Project’s total resource being converted into approximately 5.3 million short tons of boric acid reserves, and a resultant 39.5 year mine life. We plan to commence commercial construction in the second half of calendar year 2026 and are targeting initial commercial production in the second half of calendar year 2028.

We plan to continue to operate the SSF for the foreseeable future to provide additional boric acid to potential customers, advance the design of our commercial-scale wellfield design and operating methods, and refine the production process for our two proposed byproducts; calcium chloride and gypsum.

While our immediate focus is on our efforts to establish the proposed commercial-scale facility and our ability to commercially produce salable products, including boric acid, calcium chloride and gypsum, we remain dedicated to opportunistically developing downstream boron advanced materials processing capabilities to extract greater value out of the boron supply chain.
