Lion One Reports New High-grade Gold

Results at Tuvatu

North Vancouver, British Columbia--(Newsfile Corp. - September 14, 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 grade control drilling at its 100% owned Tuvatu

Alkaline Gold Project in Fiji.

Assay results are presented here for grade control drilling completed in the Zone 2 area of Tuvatu,

focusing primarily on the URW1, URA1 and Murau lode systems. Mining of the URA1 lode and the

URW1 lode system is ongoing and grade control drilling is being conducted in advance of future mining

in these areas (see news releases dated

April 3, 2023

and

May 18, 2023

). 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: "The results from our grade control drill

program continue to exceed expectations. The program is continuously returning very high-grade

material with excellent mining widths. As we increase our drill density at Tuvatu we continue to identify

very high-grade zones upon which to focus and prioritize our mining plan, and which will help us to add

additional tonnage to our growing stockpile of high-grade material as we ramp up to our first gold

production in Q4 2023".

Highlights of new Zone 2 grade control drilling (3 g/t Au cutoff):

19.78 g/t Au over 6.0 m (including 31.52 g/t Au over 3.0 m) (TGC-0071, from 114.0 m depth)

14.83 g/t Au over 6.0 m (including 25.16 g/t Au over 2.4 m) (TGC-0055, from 90.9 m depth)

18.08 g/t Au over 3.6 m (including 32.74 g/t Au over 1.5 m) (TGC-0073, from 90.0 m depth)

25.25 g/t Au over 2.4 m (including 149.63 g/t Au over 0.3 m) (TGC-0078, from 95.2 m depth)

45.89 g/t Au over 0.9 m (TGC-0080, from 23.4 m depth)

8.00 g/t Au over 4.8 m (including 21.05 g/t Au over 0.9 m) (TGC-0080, from 47.4 m depth)

8.52 g/t Au over 3.3 m (including 11.16 g/t Au over 1.8 m) (TGC-0053, from 13.8 m depth)

17.73 g/t Au over 1.5 m (including 20.98 g/t Au over 0.9 m) (TGC-0053, from 56.4 m depth)

14.13 g/t Au over 1.8 m (including 18.64 g/t Au over 1.2 m) (TGC-0062, from 67.5 m depth)

Note: Grade control drillhole composites are calculated using a 3 g/t Au cutoff with maximum internal

dilution intervals of 1 m at < 3 g/t Au.

Zone 2

The Zone 2 area of Tuvatu is located in the northwest part of the system along the western decline. It is

the first part of the deposit scheduled for mining and encompasses a number of distinct lode systems,

including the URW1, URA1, and Murau lode systems.

The URW1 lode system was the primary target for the current round of drilling. It consists predominantly

of narrow, high-grade to locally bonanza-grade vein arrays and vein swarms that strike approximately N-

S and dip sub-vertically to steeply east. Current modelling suggests that there are multiple separate

lodes within the URW1 lode system. The first two of these lodes, URW1a and URW1b, are currently

being mined. As reported on

July 13, 2023

and

July 27, 2023

, mineralization in these lodes is both

higher grade and more laterally extensive than initially anticipated. Grade control drilling in the URW1

area is targeting the up-dip and down-dip extensions of these lodes, 20 m to 40 m above and below the

current mine drives. The URW1 lode system has a current strike length of approximately 300 m in the N-

S direction, and a vertical extent of approximately 300 m.

Similarly, the URA1 lode is a narrow, steeply dipping, high-grade to locally bonanza-grade vein system. It

was discovered during the development of the western decline and is intersected by the decline at

approximately 75 m from the portal entrance. It trends approximately northeast-southwest and dips

steeply to the southeast. It has a current strike length of approximately 100 m, and a vertical extent of

approximately 120 m.

Plan view (top) and view looking north (bottom) of the

URA1 lode and the URW1 lode system in relation to the grade control holes reported here. Mining is

ongoing in the URA1 lode (shown in purple) and the URW1a and URW1b lodes (shown in light brown).

Additional lodes included in the URW1 lode system are shown in blue. Grade control drilling is targeting

the up-dip and down-dip extensions of these lodes, focusing primarily on the URW1a and URW1b lodes,

as evident in the bottom image.

The Murau lode system consists of a series of stacked relatively flat lying lodes that strike approximately

east-west and dip moderately to the south. Mining is scheduled to begin on the upper part of the Murau

lode system in Q4 2023. The portion of the Murau lode system that is currently targeted for mining

consists of a 110 m strike length in the east-west direction, a vertical extent of 55 m, and a down-dip

extension of 100 m.

system is scheduled to start in Q4 2023. The stacked nature of the Murau lodes and their moderate dip

to the south is visible in the right-hand image.

highlighted. 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. Underground

developments are shown in pale transparent grey to increase visibility of the mineralized intervals.

Grade control drilling is being conducted from underground as well as from near the mine portal and is

targeting near surface mineralization scheduled for mining in the next four to sixteen months. It is

targeting 5-10 m centers and is designed to provide a detailed understanding of the geometry and

mineralization of lode arrays in advance of underground development. Results from the grade control drill

program will be used to help optimize mine development and mineral extraction in these areas. The

Zone 2 grade control drill program is ongoing. Examples of mineralization observed in the Zone 2

drillholes reported here are shown in Figure 5.

A total of 83 grade control drillholes have been completed to date in the Zone 2 and Zone 5 areas at

Tuvatu, including 24 grade control drillholes included in this news release. Previous grade control drill

results are available in the news releases dated

April 25, 2023

and

June 14, 2023

.
