[Ferro-Alloys.com] Largo Provides Update on the Ongoing Exploration Program Surrounding its Maracás Menchen Mine in Brazil

• The Company is working to establish a correlation between the known mineralization intercepted from Novo Amparo North (“NAN”) to the Campbell Pit with the goal of opening a potential mineralized trend measuring more than 7 kilometres (“km”) along strike
• The Company is also reviewing exploration work south of the Campbell Pit to assess the potential of continued mineralization

-Largo Inc. ("Largo" or the "Company")is pleased to provide an update on the ongoing exploration program surrounding its Maracás Menchen Mine, including an initial phase of drilling conducted in 2023 and the further analysis of past exploration work completed at the Company’s Campbell Pit and exploration targets located both north and south of the Campbell Pit.

Daniel Tellechea, Director and Interim CEO of Largo, stated: “As a part of its ongoing operations, Largo continues to undertake exploration work in the areas surrounding the Campbell Pit to both optimize current operations and plan for future development and expansion through the identification and conversion of resources. This exploration program aims to expand our understanding of the mineralization surrounding the Campbell Pit so that we may gauge the possibility of continued mineralization north and south of the Campbell Pit. With analysis of recent drilling and historical exploration work underway, we anticipate providing the market with updates as our program progresses."

Exploration Program Overview

Largo is working to expand its knowledge and establish a correlation with the known mineralization intercepted to the north of the Campbell Pit where, in 2021, mineral reserves and resources were reported in the Company’s current technical report at the Campbell Pit, Gulçari A Norte (“GAN”) and Novo Amparo Notre (“NAN”). Currently, the Company is exploring the potential for a 7 km trend of mineralization between the Campbell Pit and the satellite deposits (from south to north); GAN, São José (“SJO”), Novo Amparo, and NAN (collectively, the “Northern District”).

Additionally, the Company is also working to understand and establish a correlation with the known mineralization intercepted south of the Campbell Pit, which includes further analysis of exploration work performed on satellite deposits (from north to south): Gulçari A Sul, Agua Branca, Jacaré, Braga, Ilha Grande, and Rio de Contas (collectively, the “Southern District”).

2023 Drill Program

In 2022 and 2023, the Company conducted a drill program in the Northern District 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 also performing a comprehensive review of its existing exploration data in the Northern District, including, without limitation, 161 historical drill holes and 5,869 samples collected between 1981 and 2020.

The Company’s 2023 Campaign in the Northern District includes 19 new diamond drill holes aimed at improving the Company’s geological knowledge of the Campbell Pit and GAN and SJO deposits. Of those holes, six step-out holes were drilled between the Campbell Pit and GAN deposit with the aim of confirming the potential for continued mineralization. The Company believes the initial results for the six step-out holes provide greater confidence in the continuity of mineralization between the Campbell and GAN mineralized zones. Assay results from the six step-out drill holes are provided in Table 1, along with a plan view and cross-section of the drill holes in Figure 2 and 3.

The Company is in the process of analyzing its historical drill data and the remaining holes from its 2023 Campaign with results expected in Q1 2024.

Sampling, QA/QC, and Analytical Procedures

Drill core is logged, photographed and split in half using a diamond core saw at the secure core logging and storage facilities of Largo Vanádio Maracás S.A. (“LVMSA”). Half of the drill core is retained on site and the other half core is used for analysis, with samples collected on one meter sample intervals unless an interval crosses a geological contact.

The sample preparation and analytical work was carried out at the SGS facility in Belo Horizonte and the LVMSA secure on-site laboratory, which are both ISO 9001 certified laboratories. All sample results during the period have been monitored through a QA/QC program that includes the insertion of certified standards, blanks, and pulp and reject duplicate samples. Davis Tube test work was carried out on all mineralized samples.
