Lion One Reports High-Grade Gold Results from Zone 2 at Tuvatu

North Vancouver, British Columbia--(Newsfile Corp. - October 19, 2023) - Lion One Metals Limited (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 2 area of Tuvatu, focusing primarily on the Murau lode system. Mining of the Murau lode system has commenced and grade control drilling is being conducted in advance of further mining in this area. Infill drilling is being conducted to target the up-dip and down-dip extensions of the Murau lodes. The results reported here represent material that is scheduled to be mined in Q4 2023 and throughout 2024.

Lion One Chairman and CEO Walter Berukoff commented: "After celebrating our first gold pour at Tuvatu on October 10th, we now turn our focus back to grade control and infill drilling. These drill programs continue to yield positive results and to strengthen our understanding of the mineralization at Tuvatu. We are pleased to present yet another batch of high-grade results from the Zone 2 area of Tuvatu, an area which will serve to feed our brand-new mill in the mid-to-near term future."

Murau Lodes

The Murau lodes are located within the Zone 2 area of Tuvatu, along the upper portion of the western decline in the northwest part of the deposit. The Zone 2 area encompasses a number of distinct lode systems, including the URW1, URA1, and Murau lode systems. The Zone 2 area was the first to commence mining at Tuvatu and mining is ongoing in all three of these lode systems.

The current round of infill and grade control drilling in the Zone 2 area is focused on the Murau lode system, which is modelled as a series of stacked relatively flat lying lodes that strike approximately east-west and dip moderately to the south. The portion of the Murau lode system that is currently targeted for mining consists of a vertical extent of 55 m, an east-west strike length of 110 m, and a down-dip extension of 100 m.

View is to the ESE and slightly down dip along the Murau lodes. The stacked nature of the Murau lodes is visible in the image. Grade control drilling is focused on near-term mining whereas infill drilling is focused on the up-dip and down-dip extensions of the lodes.

A total of 10 infill and 11 grade control drillholes are included in this release. The infill drill program was conducted from surface and was designed to target the up-dip and down-dip extension of the Murau lodes on approximately 20 m centers. The goal of the program is to provide an increased understanding of the system's mineralization and geometry in these areas. The grade control drill program was conducted from underground on 5-10 m centers and was designed to provide much higher resolution of the Murau lode system in advance of mine development and extraction. The location of high-grade intercepts is shown in Figure 3 while examples of Murau lode mineralization are shown in Figure 4. The Zone 2 infill and grade control drill programs are ongoing. Previous drill results from the Zone 2 area can be seen in the news releases dated September 14, 2023, June 14, 2023, and April 25, 2023.

Oblique section view of the Murau lode system highlighting the high-grade intercepts from the Zone 2 infill and grade control drill program in the Murau system. View is to the ESE and slightly down dip along the Murau lodes. Downhole composite intervals with grades between 3 and 10 g/t Au are shown in orange, intervals with grades between 10 and 30 g/t Au are shown in red, and intervals over 30 g/t Au are shown in purple. Select high-grade intervals are identified. Grades shown are gold grades in g/t.

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 September 25, 2020, and prepared by Mining Associates Pty Ltd of Brisbane Qld, comprises 1,007,000 tonnes indicated at 8.50 g/t Au (274,600 oz. Au) and 1,325,000 tonnes inferred at 9.0 g/t Au (384,000 oz. Au) at a cut-off grade of 3.0 g/t Au. The technical report is available on the Lion One website at www.liononemetals.com and on the SEDAR website at www.sedarplus.ca.

Qualified Person
In accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43- 101"), Sergio Cattalani, P.Geo, 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.

QAQC Procedures
Lion One adheres to rigorous QAQC 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 re-assayed at Lion One's lab and delivered to ALS Global Laboratories in Australia (ALS) for check assay determinations. All samples for all high-grade intercepts are sent to ALS for check assays. All samples are pulverized to 85% passing through 75 microns. Gold analysis is carried out using fire assay with an AA finish. Samples that have returned grades greater than 10.00 g/t Au are then re-analyzed 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% 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 9 important pathfinder elements. All duplicate anomalous samples are sent to ALS labs in Townsville QLD 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 ICP-AES (method ME-ICP61).
