Q1 2024 Highlights

• V₂O₅ production of 1,729 tonnes (3.8 million lbs¹) in Q1 2024 vs. 2,111 tonnes produced in Q1 2023; Within the lower range of Company’s quarterly production guidance of 1,700-2,200 tonnes for Q1 2024
• Lower Q1 2024 production was expected and is largely attributable to the completion of the Company’s planned kiln refractory replacement; Annual maintenance actions were performed concurrently in the crushing, milling, ilmenite, leaching and chemical sections of the plant; The Company maintains its annual production guidance for 2024
• V₂O₅ equivalent sales of 2,765 tonnes (inclusive of 156 tonnes of purchased material) in Q1 2024 vs. 2,849 equivalent tonnes sold (inclusive of 245 tonnes of purchased material) in Q1 2023; Within the upper range of the Company’s quarterly guidance of 2,300-2,800 tonnes
• The Company produced 9,563 tonnes and sold 513 tonnes of ilmenite concentrate in Q1 2024, respectively; Ilmenite sales were below Q1 2024 guidance due to operational and administrative delays; The Company expects sales to increase in the coming months and maintains its production and sales guidance for 2024
• The Company maintains its annual cost guidance for 2024; As a result of new cost reduction and productivity measures, the Company has lowered its cost guidance for H2 2024, however, it is expected that these cost savings will be offset by higher costs in H1 2024 as a result of the extended kiln maintenance period in Q1 2024
• Negotiations regarding the Company’s previously announced signing of a non-binding letter of intent by Largo Clean Energy Corp. with Stryten Energy LLC to establish a 50:50 joint venture in the United States are ongoing

TORONTO / Apr 30, 2024 / Business Wire / Largo Inc. ("Largo" or the "Company") (TSX: LGO) (NASDAQ: LGO) today announces the implementation of extensive changes to reduce production costs and improve productivity at its Maracás Menchen Mine through several initiatives, including the reduction of haulage distances, costs of inputs as well as comprehensive review of all contracts. The Company will reduce the number of contractors by 20% in Q2 2024 and prioritize its capital expenditures for low-cost, high-return projects in order to optimize the use of cash. The Company also announces quarterly production of 1,729 tonnes of vanadium pentoxide (“V₂O₅”) equivalent and sales of 2,765 tonnes V₂O₅ equivalent in Q1 2024.

As part of the plan to increase productivity, the Company plans to increase its annual crushing capacity by approximately 220,000 tonnes or 22% by the end of Q2 2024 following the installation of a mobile crusher, dry magnetic and wet magnetic separator from inventory, which is expected to compensate for lower grades and higher silica levels resulting from increased processing of disseminated vanadium ore. These actions are expected to maintain the Company’s production capacity by providing the required throughput and grades needed to achieve its set production targets in accordance with its 2024 mining plan.

Also, starting in Q2 2024, the Company plans to feed its ilmenite plant with ilmenite feedstock from its non-magnetic ponds from ores processed in prior years. This action is expected to increase ilmenite production in 2024 as well as improve titanium dioxide (“TiO₂”) grades as non-magnetic material stored in the Company’s ponds contain higher TiO₂ grades than feedstock from current mine operations.

For the remainder of 2024, the Company expects a reduction of approximately BRL$48 million in operating expenditures and approximately BRL$12 million in ilmenite capital expenditures.

Celio Pereira, COO of Largo, Brazil, stated: "Maximizing operational output and reducing costs remain top priorities at Largo. We have identified several avenues for cost reduction at the Maracás Menchen Mine and we expect to realize the benefits of these initiatives in the second half of the year. When combined with our productivity improvement initiatives this year, these measures are expected to assist the Company in achieving its revised 2024 cost guidance and offset some of the impact of lower vanadium prices." He continued: “In Q1 2024, the operations team conducted the planned annual maintenance at the mine, which included the replacement of the kiln refractory as well annual maintenance actions performed in the crushing, milling, ilmenite, leaching and chemical sections of the plant. Following this maintenance, we also expect to remain within our annual production guidance of 9,000 to 11,000 tonnes of V₂O₅ for 2024.”

Maracás Menchen Mine Operational and Sales Results

Q1 2024 Production and Sales Overview

• Lower Expected Production in Q1 2024 Due to Kiln Refractory Maintenance: V₂O₅ production in January was 582 tonnes, with 276 tonnes produced in February and 871 tonnes produced in March, for a total of 1,729 tonnes produced in Q1 2024. Production in Q1 2024 was largely impacted by the replacement of the kiln refractory and associated restart of operations following the performed maintenance during the quarter. During this shutdown, the Company completed its yearly maintenance activities in the crushing, milling, ilmenite, leaching and chemical sections of the plant. In Q1 2024, global recoveries³ averaged 70.5%, being 15% lower than the 83.0% averaged in Q1 2023 and 11% lower than the 79.4% achieved in Q4 2023. Lower global recoveries³ achieved during Q1 2024 is largely attributable to the kiln refractory maintenance performed during the quarter. As part of its ongoing efforts to offset lower grades of ore mined in Q1 2024, the Company continued to increase mining throughput during the quarter to 604,231 tonnes with an effective V₂O₅ grade² of 0.53%, compared to 341,967 tonnes with an effective V₂O₅ grade² of 0.81% in Q1 2023. Total crushed ore also increased by 50% over Q1 2023 (344,265 tonnes) to 516,547 tonnes in Q1 2024 and 11% over the 465,619 tonnes crushed in Q4 2023.
• Sales Results in Q1 2024 In Line with Quarterly Guidance – Steel Sector Demand Remains Soft: V₂O₅ equivalent sales of 2,765 tonnes (inclusive of 156 tonnes of purchased material) was within the upper end of the Company’s quarterly guidance range for Q1 2024 but represented a 3% decrease over the 2,849 tonnes sold in Q1 2023. Spot demand remained soft in Q1 2024, primarily due to ongoing adverse conditions in the Chinese and European steel sectors. The average benchmark price per pound of V₂O₅ in Europe was $6.44 in Q1 2024, a 38% decrease from the average of $10.39 seen in Q1 2023. The average benchmark price per kg of ferrovanadium in Europe was $27.96 in Q1 2024, a 30% decrease from the average of $39.46 seen in Q1 2023.
