LION ONE UPDATES DRILL RESULTS AT TUVATU

Lion One Metals Ltd. has provided an update on composite drill results reported in the company's Aug. 10, 2023, news release.

The Aug. 10, 2023, news release reported infill and grade control drill results from zone 5 of the company's Tuvatu alkaline gold project in Fiji. Several composite gold grades reported in that news release are here updated.

Gold analysis at Tuvatu is conducted using fire assay with an atomic absorption (AA) finish. Samples that return grades over 10 grams per tonne Au are then reanalyzed by gravimetric method. The gravimetric method is considered more accurate than fire assay for high-grade samples. Lion One has therefore recently adopted a new protocol whereby gravimetric results are reported for samples that return over 10 g/t Au. In the Aug. 10, 2023, news release, composite intervals were calculated using fire assay values rather than gravimetric values, whereas high-grade individual assays were quoted using the more accurate gravimetric results. This led to a discrepancy between the composite values and the underlying assay values for certain intervals. The difference between fire assay and gravimetric analyses tends to be greater for higher-grade samples. A total of 21 composite values have been updated and are presented herein. The majority of the updated results are greater than was initially reported.

About Tuvatu

The Tuvatu alkaline gold project is located on the island of Viti Levu in Fiji. The January, 2018, mineral resource for Tuvatu as disclosed in the technical report "Technical Report and Preliminary Economic Assessment for the Tuvatu Gold Project, Republic of Fiji," dated Sept. 25, 2020, and prepared by Mining Associates Pty. Ltd. of Brisbane, Queensland, comprises 1,007,000 tonnes indicated at 8.50 g/t Au (274,600 ounces Au) and 1,325,000 tonnes inferred at nine g/t Au (384,000 oz Au) at a cut-off grade of three g/t Au. The technical report is available on the Lion One website and on the SEDAR+ website.

In accordance with National Instrument 43-101 -- Standards of Disclosure for Mineral Projects, Sergio Cattalani, PGeo, senior vice-president, exploration, is the qualified person for the company and has reviewed and is responsible for the technical and scientific content of this news release.

Quality assurance/quality control procedures

Lion One adheres to rigorous QA/QC procedures above and beyond basic regulatory guidelines in conducting its sampling, drilling, testing and analyses. The company utilizes its own fleet of diamond drill rigs, using PQ-, HQ- and NQ-sized drill core rods. Drill core is logged and split by Lion One personnel on site. Samples are delivered to and analyzed at the company's geochemical and metallurgical laboratory in Fiji. Duplicates of all samples with grades above 0.5 g/t Au are both reassayed at Lion One's lab and delivered to ALS Global Laboratories in Australia for check assay determinations. All samples for all high-grade intercepts are sent to ALS for check assays. All samples are pulverized to 85 per cent passing through 75 microns. Gold analysis is carried out using fire assay with an atomic absorption finish. Samples that have returned grades greater than 10 g/t Au are then reanalyzed by gravimetric method. For samples that return greater than 0.50 g/t Au, repeat fire assay runs are carried out and repeated until a result is obtained that is within 10 per cent of the original fire assay run. Lion One's laboratory can also assay for a range of 71 other elements through inductively coupled plasma optical emission spectrometry (ICP-OES), but currently focuses on a suite of nine important pathfinder elements. All duplicate anomalous samples are sent to ALS labs in Townsville, Queensland, and are analyzed by the same methods (Au-AA26, and Au-GRA22 where applicable). ALS also analyses 33 pathfinder elements by HF-HNO3-HClO4 acid digestion, HCl leach and inductively coupled plasma atomic emission spectroscopy (method ME-ICP61).

About Lion One Metals Ltd.

Lion One's flagship asset is the 100-per-cent-owned, fully permitted, high-grade Tuvatu alkaline gold project, located on the island of Viti Levu in Fiji. Lion One envisions a low-cost, high-grade underground gold mining operation at Tuvatu coupled with exciting exploration upside inside its tenements covering the entire Navilawa caldera, an underexplored yet highly prospective seven-kilometre-diameter alkaline gold system. Lion One's chief executive officer, Walter Berukoff, leads an experienced team of explorers and mine builders and has owned or operated over 20 mines in seven countries. As the founder and former CEO of Miramar Mines, Northern Orion and La Mancha Resources, Mr. Berukoff is credited with building over $3-billion of value for shareholders.
