Lion One Drills 1986.23 g/t Gold and 866.25 g/t Gold at Tuvatu, Grants Options

Bonanza Grade Gold Intersected Outside Current Mine Plan

North Vancouver, December 13, 2023 - Lion One Metals Ltd. (TSXV: LIO) (OTCQX: LOMLF) (ASX: LLO) ("Lion One" or the "Company") is pleased to report significant new high-grade gold results from ongoing infill and grade control drilling at its 100% owned Tuvatu Alkaline Gold Project in Fiji.

Assay results are presented here for infill and grade control drilling completed in the Zone 5 area of Tuvatu and include multiple bonanza grade gold results such as 1,986.23 g/t, 866.25 g/t, 135.60 g/t, 115.86 g/t, and many more. These exceptional drill intercepts are all located in the near surface portion of Tuvatu and are scheduled for mining in 2024 and 2025. Most of the drill holes included in this news release targeted areas outside the current mine plan and are being brought into an updated mine plan for 2024. These results therefore represent an expansion of the current near-term mine plan.

Lion One Chairman and CEO Walter Berukoff commented: "We're very pleased with the results from our Zone 5 infill and grade control drill program. These incredible results add to the growing list of exceptional drill results returned from Tuvatu and provide strong support for our ongoing mining efforts in Zone 5. We're excited to expand our near-term mine plan in Zone 5 and look forward to mining these areas in 2024 and 2025."

• 1986.23 g/t Au over 0.6 m (TUDDH-696, from 206.1 m depth)
• 198.75 g/t Au over 1.5 m (including 866.25 g/t Au over 0.3 m) (TGC-0116, from 109.9 m depth)

Zone 5

The Zone 5 area of Tuvatu is located along the main decline and includes the principal north-south oriented lodes at Tuvatu (UR1, UR2, UR3), the principal northeast-southwest oriented lodes (UR4 to UR8), and several smaller lodes to the west of the main decline (URW2, URW2A, URW3). The lodes in Zone 5 are all steeply dipping structures. Zone 5 represents the upward extension of the Zone 500 feeder zone, which consists of a wide zone of very high-grade mineralization containing intercepts such as 20.86 g/t Au over 75.9 m (TUG-141) and 17.52 g/t Au over 23.7 m (TUDDH-608).

A total of 4 grade control and 8 infill drillholes are included in this news release. The grade control and infill drillholes reported here represent a continuation of the Zone 5 drill program reported in the November 2, 2023 news release.

Grade Control Drilling

The purpose of the Zone 5 grade control drill program is to provide a detailed understanding of the mineralization and geometry of the UR1, UR2, and URW3 lodes both above and below the main decline. The grade control drillholes reported in this news release were designed to target an area down-dip of the current underground developments, as well as to test the northern extension of the UR1 lode proximal to the main decline. The grade control drillholes reported here were drilled on 20 m centers and will be followed up with additional drilling to increase drill density to 10 m centers in advance of mining. The area targeted by these grade control drillholes is outside the current PEA mine plan but is being brought into the mine plan for 2024. This includes the bonanza grade intersect of 866.25 g/t gold, which occurs within a 1.5 m interval of 198.75 g/t gold.

Infill Drilling

The purpose of the Zone 5 infill drill program is to increase knowledge and grade continuity in the portions of the UR1 to UR7 lodes located between the surface and the underground developments and to further de-risk this portion of the deposit. The infill drillholes reported in this news release consist of a northern group and a southern group. The northern group of infill drillholes were designed to infill the up-dip portions of the UR1, UR2, and URW3 lodes and to test the northern extension of the UR1 lode. These drillholes targeted areas outside the current mine plan. The southern group of infill drillholes were designed to infill the up-dip portions of the UR1 to UR5 lodes in the southern part of the deposit, and to test the northern extension of the UR6 lode. The areas targeted by infill drilling are scheduled for mining in 2024 and 2025.

CAUTIONARY STATEMENT

Visual estimates of mineral abundance should never be considered a proxy or substitute for laboratory analyses where metal concentrations or grades are the factors of principal economic interest. At Tuvatu, coarse visible gold generally correlates well to high-grade mineralization. However, the actual grades can only be determined by systematic sampling and assaying, results of which are included in Appendix 1.

QAQC Procedures

Lion One adheres to rigorous QAQC procedures above and beyond basic regulatory guidelines in conducting its drilling, sampling, testing, and analyses. The Company operates its own geochemical assay laboratory and its own fleet of 7 diamond drill rigs using PQ, HQ and NQ sized drill rods.

Diamond drill core samples are logged and split by Lion One personnel on site and delivered to the Lion One Laboratory for preparation and analysis. All samples are pulverized at the Lion One lab to 85% passing through 75 microns and gold analysis is carried out using fire assay with an AA finish. Samples that return grades greater than 0.50 g/t Au are re-assayed three times to get two assays within 10% of each other. Samples that return grades greater than 10.00 g/t Au are re-analyzed by gravimetric method, which is considered more accurate for very high-grade samples.

Duplicates of all samples with grades above 0.5 g/t Au are also delivered to ALS Global Laboratories in Australia for check assay determinations using 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 ICP-AES (method ME-ICP61). The Lion One lab can test a range of up to 71 elements through Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), but currently focuses on a suite of 9 important pathfinder elements.

The Lion One lab has implemented the Laboratory Information Management System (LIMS) to automate workflows, integrate instruments, and effectively manage samples and associated data across all analyses conducted in the lab.
