• Favorable market outlook for boric acid, with demand forecasted to exceed supply, driving prices higher.
• Strategic importance as a U.S.-based producer of critical materials, enhancing domestic supply chain security.
• Byproducts (calcium chloride and gypsum) provide additional revenue streams and reduce net operating costs.

Negatives

• The initial capital cost of US$435 million is substantial and requires significant financing.
• Economic analysis relies on forward-looking statements and assumptions, which are subject to change based on macroeconomic conditions and operating strategy.
• Further engineering (FEL-3) and a full feasibility study are required to refine cost estimates and optimize design.
• Only 41% of the total resource has been converted to reserves, with additional conversion dependent on future EPA authorizations and mine plan updates for Blocks 1 and 3.
• Magnesium removal in the impurity circuit is highly pH dependent, requiring precise control to minimize boron losses and prevent negative impacts on leaching efficiency.
• The boric acid market is opaque, with pricing highly influenced by negotiated contracts and its duopolistic nature, making price forecasting challenging.

Risks

• Ability to maintain and modify existing permits, including obtaining new or amended Waste Discharge Requirements (WDRs) for evaporation ponds and final EPA UIC permit modifications based on horizontal well performance.
• Successful financing of the company and the proposed commercial-scale facility.
• Fluctuations in market value and demand for boric acid, calcium chloride, and gypsum.
• Uncertainties in mineral resource and reserve estimates and assumptions, and the potential for future revisions.
• Ability to expand mineral resources and convert additional resources to reserves.
• Availability and cost of energy to operate the facility, including natural gas and electricity.
• Geotechnical and hydrological model assumptions, including potential for fluid migration, capture, and wellbore collapse.
• Risk of impurity buildup in recycled process streams negatively impacting boron leaching efficiencies.
• Challenges in optimizing crystal growth and particle size distribution to meet customer specifications.
• Potential for improper material selection in equipment, piping, and instrumentation due to the harsh nature of the pregnant leach solution, leading to safety, production, or quality issues.
• Environmental impacts, including gaseous and particulate emissions, gypsum stockpiles, wastewater discharge, and solids waste handling.

Future Outlook

The company targets large-scale commercial production in 2028, with optionality for future expansion phases to increase production tonnage and develop value-added boron derivatives. Management expects the tight supply-demand balance in the global boric acid market to continue or worsen, leading to elevated pricing. The next steps involve progressing to Front End Loading Stage 3 (FEL-3) engineering and a full feasibility study, securing bankable off-take agreements, and confirming the mine plan through continued operation of horizontal wells.

Management Comments

• "As we target large-scale commercial production in 2028, we look toward the economic potential of the Project, which we expect will provide high paying jobs in California and be a significant long-term U.S. producer of boron to maintain the security of the boron supply chain in the United States."

Industry Context

The global boron market is characterized by an oligopoly, with two major companies dominating approximately 85% of global supply. The market study indicates a tight supply-demand balance for boric acid, with demand projected to outpace supply, leading to elevated prices. This project positions 5E Advanced Materials as a significant new entrant, targeting approximately 11% of current global boric acid demand, addressing supply chain security concerns for critical materials in the U.S. and globally. The company draws parallels to the lithium market a decade prior, anticipating similar growth dynamics driven by future-facing applications like EVs, permanent magnets, semiconductors, and nuclear energy. The decline in synthetic gypsum supply due to the phase-out of coal-fired power plants also creates a market opportunity for the project's gypsum byproduct.

Comparison to Industry Standards

• The global boric acid market is dominated by two major suppliers, Rio Tinto (U.S.) and Eti Maden (Turkey), with 5E's project aiming to become a significant new producer.
• The project's targeted 130,000 short tons per year of boric acid production represents approximately 11% of current global boric acid demand, positioning it as a material new supply source.
• The U.S. calcium chloride market is dominated by two large public companies, one operating a former Dow plant in Michigan and another with brine-based and HCl/limestone facilities, with the U.S. being a net importer.
• Major U.S. gypsum producers include USG, National Gypsum, and Georgia-Pacific, with synthetic gypsum from coal-fired power plants typically having high purity (95-99%).
