Daniel Tellechea, Interim CEO of Largo, stated: "The Company continues to improve the operational efficiency of its Maracás Menchen Mine, and saw a considerable improvement in production results in the fourth quarter of 2023. As a result, the Company managed to achieve its annual production and sales guidance for 2023. The Company continues to place as many units as possible in the premium yielding high purity vanadium sector, achieving a record production of 1,670 tonnes of high purity V ₂ O ₅ equivalent in Q4 2023, representing 60% of the Company's quarterly V ₂ O ₅ output. This improvement is expected to partially offset the impact of lower vanadium prices in Q4 2023, which fell to their lowest level in approximately two years, and lower sales volumes compared to Q4 2022.

He continued: "In Q4 2023, we continued to ramp up our ilmenite concentrate plant and are pleased to provide the first annual guidance for this material in 2024. With a substantial investment in this new plant in 2022/2023, we look forward to reaping the benefits of diversifying Largo's product offering and revenues in 2024 from expected ilmenite sales as by-product of our traditional vanadium operations. We completed our first 500 tonne ilmenite sale in January 2024 and expect to sell between 8,500 – 10,500 tonnes in Q1 2024. For the coming year, it is our priority to remain focused on optimizing our operations, reducing costs, and achieving our production and sales targets as we continue to navigate a lower vanadium price environment. Lastly, Largo remains dedicated to advancing its exploration program surrounding the Maracás Menchen Mine as we strive to plan for future growth."

The Company's goal for this program is to establish a potential mineralized trend measuring more than 7 kilometres ("km") along strike by establishing a correlation between the known mineralization intercepted between Novo Amparo North ("NAN") to the Campbell Pit ( see press released dated December 18, 2023 ).
  • In 2022 and 2023, the Company conducted a drill program north and south of the Campbell Put consisting of 19 drill holes and 245 surface samples, 148 infill holes in the Campbell Pit and 33 holes in the Southern District (the " 2023 Campaign ")The Company is in the process of analyzing its historical drill data and the remaining holes from the 2023 Campaign with results expected in Q1 2024.
  • In 2024, the Company anticipates completing approximately 15,300 metres of exploration drilling with efforts primarily focusing on areas north and south of the Campbell Pit with known magnetic and geochemical anomalies. Exploration efforts will also focus on concessions surrounding the Maracás Menchen Mine that require drilling in order to maintain good standing in accordance with the applicable rules and regulations in Brazil. The Company's 2024 drilling campaign is expected to begin in February 2024.

Non-GAAP ⁵ Measures

The Company uses certain non-GAAP financial performance measures in this press release, which are described in the following section.

Cash Operating Costs

The Company's press release refers to cash operating costs per pound, a non-GAAP performance measure, in order to provide investors with information about a key measure used by management to monitor performance. This information is used to assess how well the Maracás Menchen Mine is performing compared to plan and prior periods, and also to assess its overall effectiveness and efficiency. Cash operating costs includes mine site operating costs such as mining costs, plant and maintenance costs, sustainability costs, mine and plant administration costs, royalties and sales, general and administrative costs (all for the Mine properties segment), but excludes depreciation and amortization, share-based payments, foreign exchange gains or losses, commissions, reclamation, capital expenditures and exploration and evaluation costs. Operating costs not attributable to the Mine properties segment are also excluded, including conversion costs, product acquisition costs, distribution costs and inventory write-downs. These costs are then divided by the pounds of vanadium sold that were produced by the Maracás Menchen Mine to arrive at the cash operating costs per pound. This measure differs to the new total cash costs non-GAAP measure the Company uses to measure its overall performance (see Company's latest Management Discussion and Analysis). These measures, along with revenues, are considered to be one of the key indicators of the Company's ability to generate operating earnings and cash flow from its Maracás Menchen Mine. These cash operating costs measures do not have any standardized meaning prescribed by IFRS and differ from measures determined in accordance with IFRS. These measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. These measures are not necessarily indicative of net earnings or cash flow from operating activities as determined under IFRS.
