Over the past three years, our geology and operations teams have made significant progress in advancing the Company’s exploration and project planning, expanding both Mineral Reserves and Resources, which has extended mine life by an additional 13 years over Largo’s previous 2021 Technical Report. While head grades have decreased following the addition of new ore deposits and further understanding and interpretation of the Company’s ore bodies, this knowledge will allow us to better optimize our production plan going forward and maximize long-term resource planning and extraction. Additionally, the economic scenarios presented in the 2024 Technical Report, including a post-tax NPV7% of $1.1 billion and undiscounted accumulated cash flows of $3.8 billion over the life of the Project, demonstrate the Project’s ability to generate sustainable value subject to the outlined CAPEX and cost scenarios."

He continued: "In the long-term, we see growing demand for our products, particularly Largo’s high-quality vanadium, as industries and governments increasingly prioritize energy storage and the development of advanced technologies, particularly in the aerospace sector. Largo is well-positioned to meet this demand, with a significant resource base to support future production scenarios. Additional growth projects such as implementing a TiO2 pigment production in Camaçari, along with ongoing exploration at the Campbell-GAS connection and platinum-palladium exploration opportunities are expected to enhance overall results at the Company. These initiatives, combined with the outlined expansion scenarios, present a solid plan to strengthen Largo’s role as a key player in the vanadium and titanium markets, meeting the critical material needs of a transitioning global economy.”

Updated Vanadium/Titanium Project Overview and Timelines

The Company’s 2024 Technical Report outlines a comprehensive plan for the proposed development of its Project, highlighting key milestones across the 31-year project lifecycle. The proposed timeline for the Project is designed to seek ways to optimize the extraction of vanadium and titanium Resources, to ensure consistent production rates while progressively developing multiple pits. Contingent on securing the necessary financing and approvals, the potential strategic expansion of the Project’s various processing facilities aims to meet future production goals, particularly in enhancing TiO2 pigment production. Potential ramp-ups and expansions would align with the Company's long-term objectives to maximize Resource utilization and market presence with high-quality vanadium and titanium products.

Outlined Project and Mining Development Phases:

• 2023 – 2032: Continued Mining at Campbell Pit: Mining operations will focus on the Campbell Pit, extracting vanadium-rich ore to meet the production target of 2.6 million tonnes per annum (“mtpa”) for the next nine years;
• 2032 – 2054: Sequential Mining from NAN, SJO, NAO, and GAN Pits: Following the Campbell Pit, mining would transition sequentially to the NAN, SJO, NAO, and GAN pits, ensuring a continuous feed of 3.4 mtpa to the vanadium and titanium processing plants.

Proposed Production Timeline:

• Vanadium Processing
  • 2027: The installation of a second kiln, designed for a 20-tonne-per-hour feed rate to increase the capacity of the vanadium operations
• Ilmenite Concentration Plant:
  • 2023: Production capacity of 100 kilotonnes per year (“ktpy”)
  • 2025: Increased capacity to 122 ktpy
  • 2026: Capacity reaches 196 ktpy
  • 2029: Full ramp-up to 265 ktpy to meet the Company’s expected TiO2 pigment plant demand
• TiO2 Pigment Plant:
  • 2029: Construction in Camaçari, Bahia begins, with an initial production capacity of 30 ktpy
  • 2030: Capacity increases to 60 ktpy
  • 2031: Full production of 100 ktpy achieved

The outlined phased approach presents scenarios for maintaining stable production over the long term, supporting the Company’s growth objectives and its ambitions to remain a reliable and secure supplier in the vanadium and TiO2 markets. The proposed mining plan, along with potential expansions of processing capabilities—including the Ilmenite and TiO2 pigment plant—are expected to position the Company for sustained market leadership and resource optimization.

Significant Increase In Largo’s Mineral Resource and Reserves

The Company’s updated 2024 Mineral Resource and Reserve estimates demonstrate considerable advancements in exploration and development efforts at Largo over the last three years. Based on an extensive exploration program comprising 650 diamond drill holes, totaling over 114,000 meters (“m”) and incorporating more than 47,000 samples (45,814.24 m), the new geological models provide a strong foundation to support future production scenarios outlined in the 2024 Technical Report. This update includes newly reported Indicated and Inferred Resources at SJO and NAO, with additional Inferred Resources delineated at Jacaré (“JAC”), GAS, and Rio de Contas (“RIOCON”).

The Company has significantly increased both its Mineral Reserves and Resources through these exploration efforts, driven by a deeper understanding and improved interpretation of the ore bodies. While this additional knowledge has contributed to a substantial increase in the Company’s overall resource base, it has also led to a reduction in head grades, as the knowledge and understanding of more complex ore zones, including lower-grade pegmatite bodies, have been incorporated into the models. This is expected to enable the Company to optimize future mining and processing activities, balancing anticipated resource growth with long-term operational efficiency.

Future Growth Opportunities at the Project

The Company is actively advancing several long-term growth initiatives, designed to enhance resource potential and production capabilities at the Project. These initiatives will focus on both expanding the Company's resource base and leveraging new technologies to optimize future operations.

1. Additional Exploration and the Campbell-GAS Deposit Connection: The Company is undertaking an exploration program to confirm mineralization between the Campbell Pit and the GAS deposit. Previous drilling at the GAS target identified 11.3 mt of Inferred Resources, grading 0.58% V2O5 and 8.48% TiO2, with concentrate grades of 2.31% V2O5 and 2.22% TiO2. The relatively short distance of approximately 800 m between the Campbell Pit and the GAS deposit presents a strong opportunity to enhance the Company’s resource base by connecting these deposits. If successful, this would increase the overall ROM material close to the Company’s existing processing facilities as compared to other more northerly deposits.
2. PGM Opportunities: At the end of 2023, the Company resumed studies to further explore the existence of PGMs within its non-magnetic tailings ponds. Auger samples from the non-magnetic tailings ponds revealed promising results, with notable platinum and palladium grades, including 3.0 meters grading 0.410 g/t Pt and 0.209 g/t Pd. This follows historical data from past exploration efforts at the Company, which also demonstrated significant PGM mineralization (see press release dated March 5, 2024). By further reviewing and analyzing historical drill data, the Company aims to develop a comprehensive PGM resource model that could further enhance the potential of future mining operations and provide a potential new revenue opportunities alongside its vanadium and ilmenite operations. PGMs are highly valuable due to their applications in catalytic converters and the automotive industry, presenting a major growth opportunity if these studies yield positive results.
