Largo Reports Third Quarter 2023

Production and Sales Results and Begins Hot

Commissioning of its 6.1 MWh Vanadium

Redox Flow Battery; Production and Cost

Guidance Remains Unchanged

Q3 2023 and Other Highlights

• V2O5 production of 2,163 tonnes (4.8 million lbs1) vs. 2,906 tonnes produced in Q3

2022, including 644 tonnes in July, 775 tonnes in August and 744 tonnes in

September

• Global V2O5 recovery rate3 of 76.9% in Q3 2023 vs. 80.7% in Q3 2022

• V2O5 equivalent sales of 2,385 tonnes vs. 2,796 tonnes sold in Q3 2022

• The average benchmark price per lb of V2O5 in Europe was $8.03, a 2.5% decrease

from the average of $8.23 seen in Q3 2022

• Ramp up of its new ilmenite concentration plant continues with ilmenite concentrate

production of 350 tonnes in August and 700 tonnes in September

• Largo Clean Energy (“LCE”) completed site acceptance testing of its Enel Green

Power España (“EGPE”) 6.1 MWh vanadium redox flow battery (“VRFB”)

deployment and submitted results to EGPE, with the expectation of completing the

hot commissioning phase of the battery; Provisional acceptance is expected in Q4

2023

• 2023 production, sales, cost and capital expenditures guidance remain unchanged

TORONTO--(BUSINESS WIRE)--October 17, 2023--Largo Inc. ("Largo" or the "Company")

(TSX: LGO) (NASDAQ: LGO) today announces quarterly production of 2,163 tonnes (4.8

million lbs1) and sales of 2,385 tonnes of vanadium pentoxide (“V2O5”) equivalent, respectively,

in Q3 2023.

Daniel Tellechea, Interim CEO and Director of Largo, stated: “Despite production setbacks in

the third quarter caused by the previously reported accident in our chemical plant and delays in

the ramp of our new magnetic separator in the crushing plant, Largo remains steadfast in its

commitment to rectifying operations in the fourth quarter and has maintained its production,

cost and capex guidance for 2023. Our top priority is safety and returning production to a more

normalized level through the strengthening of operational efficiencies at the mine and crushing

plant.” He continued: “On the Largo Clean Energy front, we are pleased that hot commissioning

and provisional acceptance of the EGPE 6.1 MWh VRFB deployment are in the final stages of

completion, marking an exciting step towards the conclusion of LCE’s inaugural vanadium

battery project. Furthermore, the review of strategic alternatives to unlock and fully maximize

the value of LCE remains ongoing and has garnered interest from various parties thus far. While

near-term vanadium demand and prices are challenging on the back of weak demand from the

steel sector, we are optimistic about future demand projections, particularly driven by an

explosive growth of future VRFB deployments in the coming years.”

Q3 2023 and Other Additional Highlights

• Despite higher mining throughput in Q3 2023 (447,165 tonnes) compared with Q3 2022

(351,450 tonnes), V2O5 production from the Maracás Menchen Mine was impacted in

July and August as a result of the accident at the chemical plant in July, while production

in September was affected by the lack of availability of the crushing circuit in September.

Mitigative measures to increase production levels in future quarters, including increasing

crusher availability and recommissioning evaporation sections of the chemical plant are

underway. High purity V2O5 equivalent production represented 38% of the total quarterly

production in Q3 2023.

• The global recovery3 achieved in Q3 2023 was 76.9%, representing a 5% decrease from

the 80.7% achieved in Q3 2022 and 5% lower than the 81.0% achieved in Q2 2023. The

global recovery3 in July was 78.8%, with 77.7% achieved in August and 73.6% achieved

in September. Lower recovery levels achieved during the quarter relate production

impacts mentioned previously. The Company produced 87,447 tonnes of concentrate

with an effective grade2 of 2.94%.

• V2O5 equivalent sales of 2,385 tonnes (inclusive of 256 tonnes of purchase material) were

in line with expectations for Q3 2023 but represented a 17% decrease in tonnes sold over

Q3 2022. The Company’s sales remain geographically diversified, with North America

and Europe each representing approximately one third of total sales, and South America

and Asia representing the remaining third. Spot demand was soft in Q3 2023, primarily

due to adverse conditions in the Chinese and European steel industries. However, strong

demand for high purity vanadium products continued.

• Effective Monday, October 9, 2023, Mr. Celio Pereira assumed the role of Chief

Operating Officer (COO) of Largo Vanádio de Maracás S/A (“LVMSA”). This decision

follows the departure of Álvaro Resende, to whom the Company thanks for his many

years of service. Celio's appointment is a testament to his excellent track record and the

trust and confidence placed in him by the Board and management of Largo. Celio brings

to LVMSA over 8 years of operational and technical expertise, honed during his tenure at

the Maracás Menchen Mine. He will be instrumental in implementing a culture of safety

and operational efficiency at the mine. Following this operational restructuring, the

Company expects an enhancement in operational efficiencies at the crushing and milling

circuits, as well as the increasing throughput to the ilmenite plant.
