5E Advanced Materials Inc (NASDAQ: FEAM) is a boron mineral development company focused on advancing its Fort Cady Project in California toward commercial-scale production of boric acid, calcium chloride, and gypsum via in-situ leaching. The company has no commercial revenue as of the FY2025 10-K (filed September 29, 2025) and funds operations through equity and debt issuances. In August 2025, FEAM published a Preliminary Feasibility Study (PFS) targeting a 130,000 short ton per annum boric acid plant at Phase 1, based on approximately 5.3 million short tons of boric acid reserves at an average grade of 8.03% B2O3 and an initial mine life of 39.5 years. The PFS projects boric acid pricing starting at $1,248 per short ton in 2028, with calcium chloride at $174 per short ton and gypsum at $33 per short ton across the life of mine. As of the filing date, FEAM operates a small-scale pilot facility (SSF) producing boric acid at one short ton per day and has converted two existing vertical wells to horizontal-side tracks extending approximately 1,500 feet into colemanite zones.

Revenue model

Pre-revenue development stage. Operations are funded through equity raises and convertible note issuances. No commercial product sales are recorded in FY2025 or FY2024 based on available filing excerpts.

Products and services

Boric acid (primary product, targeting 130,000 short tons per annum at commercial scale per PFS issued August 2025), calcium chloride, and gypsum. All three are derived from in-situ leaching of colemanite boron deposits at the Fort Cady Project.

Customers and end markets

End markets cited in the FY2025 10-K include decarbonization, food security, national defense, and domestic critical materials supply. The company runs a customer qualification program for boric acid, with sulfur content maintained below 100 ppm to meet customer specifications. No specific customers or revenue concentrations are disclosed in the filing excerpts.

Value-chain role

Upstream mineral developer and early-stage processor. FEAM extracts boron via in-situ leaching, processes leachate at its Small-Scale Facility into boric acid, and plans to deliver finished product by truck. The company is dependent on third-party energy suppliers for natural gas and electricity during development and operations.
