Paulo Misk, President and Chief Executive Officer of Largo, stated: "I am very encouraged by the ongoing development of our clean energy division as highlighted by the recent signing of our first milestone battery sales contract with a world-class partner, EGPE. We believe this further validates the Company's innovative value proposition for energy storage customers and underpins a significant growth opportunity for Largo." He continued: "In Q2 2021, the Company concluded the commissioning and ramp up activities associated with its kiln and cooler upgrades, including improvements of the mining, crushing and milling circuits to support a new nameplate production capacity of 1,100 tonnes of V ₂ O ₅ per month. We expect to reach the new nameplate capacity in Q3 2021. Following these activities, global recoveries ² began to improve in Q2 2021 and the Company achieved 82.2% in June. Looking ahead, we expect to achieve our 2021 production and sales guidance through a rigorous operating and sales program during the remainder of the year.

"We are also pleased to report that commissioning of the Company's V ₂ O ₃ processing plant has begun and production is expected by the end of the third quarter. V ₂ O ₃ is an important high purity material required in the manufacturing of master alloys, chemical products and electrolyte used in VRFBs. The addition of this product should increase the Company's high purity market share as this sector gradually recovers and will support the development of our clean energy division with its use in the manufacturing of electrolyte." He concluded: " Vanadium prices continued to edge higher in Q2 2021 following limited material availability and increased demand from the steel industry. During Q2 2021, the average European Fastmarkets Metalbulletin price per lb of V ₂ O ₅ was US$8.19, representing an increase of 16% over Q1 2021 and 33% above the average price seen in Q2 2020. We expect vanadium prices to remain elevated and well above long-term averages throughout the second half of 2021."

A summary of the Company's Q2 2021 production and sales results is presented below:

Q2 2021 Production Results

Total production from the Maracás Menchen Mine was 3,070 tonnes of V ₂ O ₅ in Q2 2021, representing a 20% increase over Q2 2020 and a 55% increase over Q1 2021. V ₂ O ₅ production was 1,092 tonnes in April, with 1,075 tonnes being produced in May and 903 tonnes in June. Lower production seen in June was largely due to a reduction in the total ore mined as a result of the Company's transition to a new mining contractor. The full transition was completed in Q2 2021.

In Q2 2021, 340,734 tonnes of ore with an effective V ₂ O ₅ grade ³ of 1.15% were mined compared to 257,357 tonnes in Q2 2020 with an effective V ₂ O ₅ grade ³ of 1.20%. The Company also produced 98,372 tonnes of concentrate ore with an average V ₂ O ₅ grade of 3.23% in Q2 2021 compared to 99,059 tonnes in Q2 2020 with an average V ₂ O ₅ grade of 3.20%.

The Company achieved a global recovery ² of 79.9% in Q2 2021, being 1% lower than the 80.8% achieved in Q2 2020 and 3% higher than the 77.4% achieved in Q1 2021. The global recovery ² in April was 78.8%, with 78.5% achieved in May and 82.0% achieved in June. Global recoveries ² in April and May were largely impacted by the commissioning and ramp up activities associated with the kiln and cooler upgrades. These activities concluded in Q2 2021.

Clean Energy Division Update

During Q2 2021, Largo Clean Energy Corp. (" LCE ") remained focused on obtaining certification of its VCHARGE± VRFB system under UL1973 and UL9540 requirements to support expected 2022 project deployments. In addition, building modifications of its product development and stack manufacturing center are expected to commence shortly which will enable the installation and commissioning of stack manufacturing capacity and test equipment. The Company continues the hiring of additional personnel to support the achievement of its set targets and timelines.

On July 20, 2021, the Company announced that LCE entered into its first VCHARGE± VRFB system sales contract with EGPE. Under the contract, LCE is obligated to deliver a 5 hour 6.1 MWh VCHARGE± system for a project in Spain with expected commissioning in Q4 2022, subject to receipt of notice to proceed from EGPE within the next 180 days.
