Lion One Drills 6.6 m of 80.78 g/t Au in the Main Zone at Tuvatu, Fiji

North Vancouver, British Columbia–(Newsfile Corp. – August 10, 2023) – Lion One Metals Limited (TSXV: LIO) (OTCQX: LOMLF) (ASX: LLO) (“Lion One” or the “Company”) is pleased to report exceptional 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 the deposit, which encompasses the near-surface portions of lodes UR1 to UR8, as well as URW2A and URW3. The Zone 5 area of the deposit is scheduled for mining in early 2024. Grade control drilling is being conducted in anticipation of future mining and is therefore focused on the first part of Zone 5 to be mined whereas infill drilling is focused on the parts of Zone 5 scheduled to be mined later. Zone 5 includes the main north-south oriented lodes at Tuvatu (UR1, UR2, and UR3), and represents the upward extension of the Zone 500 feeder zone, which includes intercepts such as 20.86 g/t Au over 75.9 m (TUG-141), 12.22 g/t Au over 54.90 m (TUDDH-601), and 17.52 g/t Au over 23.7 m (TUDDH-608) (see June 6, 2022, August 15, 2022 and November 7, 2022 news releases). Zone 5 will be the second major part of Tuvatu to commence mining after mining in the URW1 area began on May 18, 2023. Once Zone 5 is in production, Tuvatu will have two major zones of very high-grade, near surface mineralization developing and producing simultaneously.

Highlights of new Zone 5 drilling:

• 80.78 g/t Au over 6.6 m (including 793.24 g/t Au over 0.6 m) (TUDDH-643, from 242.7 m depth)
• 261.93 g/t Au over 1.8 m (including 1839.55 g/t Au over 0.3 m) (TGC-0067, from 48.2 m depth)
• 93.05 g/t Au over 0.9 m (including 300.47 g/t Au over 0.3 m) (TGC-0067, from 53.3 m depth)
• 9.96 g/t Au over 6.8 m (including 165.95 g/t Au over 0.3 m) (TUDDH-653, from 89.5 m depth)
• 17.48 g/t Au over 3.3 m (including 95.63 g/t Au over 0.6 m) (TUDDH-643, from 111.6 m depth)
• 17.2 g/t Au over 2.7 m (including 124.52 g/t Au over 0.3 m) (TUDDH-651, from 194.5 m depth)
• 11.84 g/t Au over 3.9 m (including 48.27 g/t Au over 0.6 m) (TUDDH-650, from 203.5 m depth)
• 9.53 g/t Au over 3.9 m (including 55.08 g/t Au over 0.3 m) (TUDDH-653, from 53.0 m depth)
• 15.96 g/t Au over 1.5 m (including 72.46 g/t Au over 0.3 m) (TUDDH-637, from 161.7 m depth)
• 14.93 g/t Au over 1.5 m (including 23.89 g/t Au over 0.9 m) (TUDDH-650, from 192.6 m depth)

Infill drilling is being conducted from surface on approximately 20 m centers while grade control drilling is being conducted from underground on 5-10 m centers. Infill drilling is considered an intermediate stage of drilling and is designed to increase understanding of the deposit in targeted areas whereas grade control drilling is designed to provide much higher resolution and detailed understanding of the geometry and mineralization of lode arrays in advance of underground development.

Zone 5

Zone 5 is located along the main north-south corridor of Tuvatu and represents the shallower portions of the UR lodes, occurring between the surface and the exploration decline. It encompasses a series of closely spaced, narrow, high-grade to locally bonanza-grade vein arrays that strike approximately north-south to northeast-southwest and dip sub-vertically to steeply east. The lodes in the center of the corridor (UR1, UR2, UR3, URW2, URW3) are very closely spaced and strike north-south. They have an east-west width of approximately 75 m and a strike length of approximately 600 m. The lodes in the east and southeast (UR4, UR5, UR6, UR7, UR8) strike approximately northeast-southwest, are slightly wider spaced, and fan out to the east. They have a northwest-southeast width of approximately 250 m and a strike length of approximately 600 m (see Figure 2).

The lodes within the main corridor at Tuvatu have a vertical extent in excess of 1000 m and appear to coalesce at approximately 450 m depth where they transition to Zone 500 – the very high-grade feeder zone at Tuvatu. Zone 5 is located approximately 250 m directly above Zone 500. The results reported in this news release therefore represent high-grade mineralization that is the direct vertical upward extension of the Zone 500 feeder zone. The region between Zone 5 and Zone 500 has only been tested by relatively wide-spaced exploration drilling. The results reported here represent the initial stages of a more systematic infill and locally grade control drilling program in Zone 5, which has a strike length in excess of 300 m in the north-south direction and a vertical extent of approximately 250 m (see Figure 3).

Infill Drilling

A total of 14 Zone 5 infill drillholes are included in this news release. The infill drill program was drilled from surface and was designed to target the near-surface portions of the main UR lodes. The goal of the program is to increase the understanding of mineralization and lode geometry in this part of the deposit, which is scheduled for mining in late 2024 and beyond. Zone 5 mining will progress upwards from the exploration decline and thus the lower portions of Zone 5 are the first scheduled for extraction. The Zone 5 infill drill program is ongoing. Examples of mineralization observed in the Zone 5 infill drillholes are shown in Figure 4.

Grade Control Drilling

A total of 12 grade control drillholes have been completed to date in the Zone 5 area of Tuvatu, six of which are reported here. Results from the first six grade control drillholes completed in Zone 5 were reported in the news release from June 14, 2023. The grade control drillholes were drilled from underground and were designed to target the Zone 5 blocks scheduled for near-term production. This area is planned to be mined in early 2024 and results from the grade control drill program will provide increased understanding of the geometry and continuity of mineralization in those blocks and will help to optimize mine development and extraction in the near future. The grade control drill program is on schedule and the results to date confirm the local understanding of the Zone 5 geological model. Zone 5 grade control drill programs are ongoing. Examples of mineralization observed in the grade control drillholes are shown in Figure 5.

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.sedar.com.

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).
