HOUSTON, May 11, 2023 (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 ("Project"), is pleased to announced it has updated its Technical Report Summary for the Project and released its financial results for the quarter ended March 31, 2023.

BUSINESS UPDATE

Technical Report Update and Larger Scale Facility

During the quarter, the 5E team spent significant time updating the Company’s initial assessment Technical Report Summary, which has been filed with the Securities and Exchange Commission ("SEC") and prepared in accordance with the SEC S-K Regulations (Title 17, Part 229, Items 601 and 1300 until 1305). A dedicated internal and external team pooled their professional and technical expertise to publish a report that the Company believes highlights a world-class resource, management's firm understanding and direction for the business, and a phased approach to scale production, which can position the company to achieve profitability, generate cash flow, and reduce risk. The updated initial assessment includes a revised mineral resource estimate for boric acid and lithium carbonate, estimates for capital costs and operating expenses, and a bottoms-up economic analysis based on a phased approach to scaling production. The financial model for the economic analysis includes preliminary market studies and independent pricing forecasts for boric acid and lithium carbonate. As part of the updated technical report, the Company engaged two external EPC firms to assist management with the capital cost estimate, which the Company expects to use as the basis to stage a formal process to request proposals for detail design of the large-scale facility.

The updated Technical Report Summary outlines three phases for the larger-scale facility:

• Phase 1 targets production of 90,000 short tons of boric acid and 1,100 short tons of lithium carbonate with a targeted go-live date of the second calendar quarter of 2026.
• Phase 2 and Phase 3 targets incremental production increases of 180,000 short tons of boric acid and 2,200 short tons of lithium carbonate in each phase with a targeted go live date in the fourth calendar quarter of 2028 (Phase 2) and second calendar quarter of 2031 (Phase 3).
• Full operation includes targeting production of 450,000 short tons of boric acid and 5,500 short tons of lithium carbonate per annum.

The initial capital cost estimate outlined in the technical report for Phase 1 is $288 million before contingency and owner's costs. With the owner’s cost and a 25% contingency, Phase 1 capital is estimated at $373 million. First year full-production cash costs are targeted at $686 per short ton and the table below includes targeted financial metrics for each phase's first full-year of operation:

Market Study Results

The Company commissioned an independent third-party research firm to perform a boron market study and forward pricing forecast. The market study indicates that overall demand for boric acid is expected to increase at a CAGR of 5.4% from 2022 through 2031 while capacity increases for the same period are projected at a 5.1% CAGR. Given that the market is already nearly balanced and existing suppliers have not demonstrated an ability to immediately ramp up capacity, a systematic market deficit is expected through the next decade, driving prices higher as projected in Figure 1 below. Figure 2 below outlines the supply and demand deficit.

Figure 2: Projected market capacity versus demand, in thousands of tonnes per Kline and Company, Inc.

As the world focuses on decarbonization, food security and security of strategic and critical minerals, the forecasted pull-side demand for boron enabling future-facing applications is expected to pressure boric acid pricing higher. Further reinforcing the market study and pricing forecast is the lack of near-term supply. As 80% of the market is controlled by two producers, 5E is one of the only permitted boron resources with a proven commercially viable mineralization (calcium-based) that is likely to add meaningful supply in the next five to seven years.

Small-Scale Facility

During the quarter ended March 31, 2023, the Company substantially completed construction of the Small-Scale Facility and progressed commissioning activities. Initial production of boric acid will commence upon final clearance from the U.S. Environmental Protection Agency (EPA) under the Company’s Underground Injection Control Permit as well as successful completion of commissioning activities. Key required reports and documentation were submitted to the EPA for their approval in 2022 and the Company believes it is in full compliance with the terms of the permit. Upon final review of required documentation by the EPA, the Company expects to receive authorization to commence mining operations. Data gathered from the construction and future operation of the Small-Scale Facility will be used to optimize and improve accuracy of capital and operating estimates for the larger-scale operations, provide customer samples for qualification and future off-take agreements, and offset future operating expenses.

CEO Appointment

During the quarter, the Company announced the appointment of Ms. Susan Seilheimer Brennan as its new Chief Executive Officer. Ms. Brennan started on April 24, 2023, and has an extensive global leadership background, particularly in the battery technology and electric vehicle industries. During Ms. Brennan's first two weeks, she has implemented general, administrative and fixed cost cutting measures and will relocate the Company's headquarters to California in an effort to focus on production of boric acid and lithium carbonate.

Third Quarter 2023 Results:

As of quarter-end, the Company maintained a cash balance of $36.2 million. Construction in progress was $61.5 million, compared to $46.9 million in the prior fiscal quarter ended December 31, 2022, as the Company neared mechanical completion of the Small-Scale Facility.
