Electra Reports Q4 and Year-End 2022 Results and Provides Update on Cobalt Refinery Project and Black Mass Recycling Trial

Electra Battery Materials Corporation (NASDAQ: ELBM; TSX-V: ELBM) ("Electra" or the "Company") today reported its financial results for the quarter and year ended December 31, 2022, and provided an update on the commissioning of its cobalt refinery and its black mass recycling trial. All amounts are in Canadian currency unless otherwise stated.

"2022 was a remarkable year for Electra, filled with achievements and developments that augur extremely well for our Company and our prospects of becoming a key link in the North American EV battery supply chain," said Trent Mell, Electra's CEO. "Most notably, we made considerable progress towards our vision of commissioning North America's first cobalt sulfate refinery, we launched a plant-scale black mass recycling trial at our refinery complex north of Toronto that has already produced a number of encouraging results, and we signed a three-year strategic supply agreement with LG Energy Solution, the world's second-largest EV battery manufacturer. Equally significant, we benefitted from the adoption of the U.S. Inflation Reduction Act, which has provided a boost for our industry and includes a number of incentives that will spur further growth of the EV supply chain in North America for years to come."

Mr. Mell added, "Although some of our progress was impeded by supply chain disruptions, receipt of damaged equipment, and the impact of inflationary price pressures on our refinery project, we remain particularly encouraged by our near- and long-term prospects. Most notably, we anticipate completion of a re-baseline engineering report on our refinery project as well as the first shipment of products produced in our black mass trial in the near term.

"Over the longer term, we are encouraged by the opportunity to expand into the production of related battery materials, including nickel sulfate at our refinery complex in Ontario, and by the prospects of developing a new cobalt sulfate refinery as part of the battery industrial park being built in Bécancour, Quebec."

Mr. Mell concluded, "Key to our ongoing success will be to leverage our hydrometallurgical process expertise and the benefits of operating in North American jurisdictions where low-carbon production is possible due to an abundance of renewable energy sources."

As part of the Note Offering, Electra also announced that it purchased and cancelled all of the previously outstanding 2026 Notes at par value, plus accrued and unpaid interest. The net proceeds of the Note Offering of approximately US$14 million will be used for capital expenditures associated with the expansion and recommissioning of the Company's cobalt refinery, including buildings, equipment, infrastructure, and other direct costs, as well as engineering and project management costs.
• Issued its inaugural Sustainability Report and committed to net-zero greenhouse emissions by 2050.

Refinery Project Update

As at March 31, 2023 Electra has made the following key developments in its refinery project:

• Completed commissioning of the analytical lab, feed material handling system, including the ball mill and mixing station, filter presses, and reagent handling systems.
• Completed 90 to 95 percent of all procurement.
• Completed the erection of the solvent extraction building.
• Completed the construction of the cobalt sulfate loadout facility.
• Increased the project owners' team to 31 personnel, which includes tradespeople, engineers, operators, lab technicians, and office support staff.

On February 14, 2023 Electra announced that due to the receipt of damaged equipment critical to the completion of the refinery project and ongoing supply chain disruptions causing ongoing delays in the delivery of equipment, including components to process control systems, the Company withdrew its previous guidance relating to the refinery project's estimated capital spend and construction timelines. Subsequent inspection of the damaged equipment has determined that the falling film evaporator vessel is suitable for installation. The damaged equipment will require onsite repairs before it can be commissioned.

Also on February 14, 2023 Electra announced the launch of a re-baseline engineering report to identify the refinery's updated project scope, scheduling, and capital expenditures. This updated re-baseline engineering work, which has been undertaken by the refinery project's engineering, procurement, and construction (EPC) contractor, continues. The findings will be reviewed by an independent third-party estimator and presented to the Company's board. Although results are still pending, management anticipates that the capital costs will be higher due to inflation, construction delays and the completion of detailed engineering.

In particular, given inflationary price pressures over the past year that have negatively impacted all aspects of the refinery project, including contractor labour rates and costs for concrete, steel, and piping, Electra expects that the re-baseline engineering report will conclude that capital costs for completing the refinery project will be higher than the $105 million budget previously disclosed. The Company will require additional capital to complete final commissioning. Discussions are underway with various commercial partners, government agencies and other parties to address the funding shortfall.

Electra will provide an update on its refinery project once the re-baseline engineering report is completed.

Black Mass Trial Update

Late in 2022, Electra launched a black mass trial at its refinery complex north of Toronto to recover and recycle high-value elements from black mass, including lithium, nickel, cobalt, copper, manganese and graphite, found in shredded lithium-ion batteries.

Electra has achieved a number of encouraging results since the trial began:

• On February 14, 2023, Electra confirmed that it had successfully completed the first plant-scale recycling of black mass material in North America and recovered critical metals needed for the electric vehicle battery supply chain using its proprietary hydrometallurgical process.
• On March 13, 2023, Electra announced that it recovered lithium, a critical mineral needed for the electric vehicle EV battery supply chain. The recovery and subsequent production of a technical-grade lithium carbonate product in a plant-scale setting validate Electra's proprietary hydrometallurgical process.
• Also, in March 2023 Electra produced a mixed hydroxide precipitate (MHP) at contained metal grades for nickel and cobalt above quoted market specifications.
• Recoveries within the MHP circuit, which produces the highest value product in the black mass recycling process, have been equivalent to and at times superior to bench scale results achieved previously.
• As a result of successes achieved to date, Electra has elected to extend its black mass trial through to June 2023, beyond the initial target of 75 tonnes.

"Electra's ?Proof-Partner-Build' strategy for battery recycling is premised on demonstrating a viable refining process and then partnering with battery makers to build dedicated capacity that can be integrated into their supply chains," said Mr. Mell. "Our early success has already generated interest from battery supply chain companies who are looking for viable North American battery black mass refining solutions. Over the coming months, we expect continued validation of our hydrometallurgical process, ongoing improvements to extraction and recovery rates, and the start of product shipments to customers."

All of the Company's recovered material will be sold to third-party companies for additional processing and re-use in a number of applications. A first shipment of MHP product is expected to be delivered to downstream clients for evaluation purposes in early Q2 2023.

Pending completion of the black mass trial and evaluation of project economics expected in Q2, success could pave the way towards commercialization. Using the existing refinery footprint, infrastructure and plant equipment, Electra could quickly expand throughput to 2,500 tonnes per year of black mass under a continuous operation scenario. A desktop study is underway, and results will be shared once available. A larger facility of 5,000 tonne or more per annum of black mass is another option Electra may consider with a commercial funding partner.
