Lion One Reports High-Grade Gold Results at

Tuvatu

Grade Control Drilling in URW1 and Zone 5 Areas Returns

Grades over 100 g/t Au

North Vancouver, British Columbia--(Newsfile Corp. - June 14, 2023) -

Lion One Metals Limited

(TSXV: LIO) (OTCQX: LOMLF) (ASX: LLO)

("Lion One" or the "Company")

is pleased to report

significant 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 on both the URW1 lode system as

well as the Zone 5 area of the deposit, which encompasses the upper portion of lodes UR1, UR2, UR3,

UR4, URW2, URW3, URW1A, and UR2A (Figure 1). As reported on

May 18, 2023

, initial mining of the

URW1 lode system has already commenced and grade control drilling is being completed in advance of

mining. The Zone 5 area of the deposit is scheduled for mining in early 2024 and thus the grade control

drilling in this area is being conducted in anticipation of future mining, as well as to increase the

knowledge of the deposit in that area. Additional high-grade intersections peripheral to both the URW1

and the Zone 5 areas are also included in this release as part of the grade control program.

Highlights of new grade control drilling:

7.14 g/t Au over 21.6 m

(including 18.61 g/t Au over 5.1 m) (TGC-0042, from 73.6 m depth)

52.05 g/t Au over 2.1 m

(including 345.3 g/t Au over 0.3m) (TGC-0042, from 118.0 m depth)

23.11 g/t Au over 3.6 m

(including 125.31 g/t Au over 0.3 m) (TGC-0040, from 65.4 m depth)

19.43 g/t Au over 3.3 m

(including 80.87 g/t Au over 0.6 m) (TGC-0051, from 49.5 m depth)

21.15 g/t Au over 2.7 m

(including 67.59 g/t Au over 0.6 m) (TGC-0047, from 123.3 m depth)

9.39 g/t Au over 4.2 m

(including 67.30 g/t Au over 0.3 m) (TGC-0050, from 26.7 m depth)

10.13 g/t Au over 3.9 m

(including 38.58 g/t Au over 0.6 m) (TGC-0043, from 66.3 m depth)

33.99 g/t Au over 0.9 m

(including 100.89 g/t Au over 0.3 m) (TGC-0045, from 62.1 m depth)

78.03 g/t Au over 0.3 m

(TGC-0052, from 40.2 m depth)

Grade control drilling is being conducted on 5-10 m centers and is designed to provide a much higher

resolution of the lode arrays than compared to infill drilling, which is being conducted on approximately

20 m centers. This increased resolution provides a much better understanding of the geometry and

mineralization of the lodes and helps to optimize mine development and extraction. The grade control

drilling program is currently on schedule and the results to date confirm the local understanding of the

URW1 and Zone 5 geological models.

URW1 Grade Control Drilling

The URW1 lode system consists 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. 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.

A total of 52 grade control holes have been completed to date in the grade control drill program. Results

from the first 36 drillholes (TGC-0001 to TGC-0036) were reported on

April 25, 2023

, and the next 16

drillholes (TGC-0037 to TGC-0052) are reported here. Ten of the most recent grade control drillholes

targeted the URW1 area. Figure 2 shows the location of the most recent drillholes in relation to the

URW1a and URW1b lodes, as well as to the main Tuvatu decline. Grade control drilling on the URW1

lode system has been conducted from underground from both the main decline and the historical

exploration decline, and has been designed to target an 80 m strike section within the overall 300 m

strike length of the URW1 system.

recent grade control holes in relation to the URW1 lode system. The URW1 lode system consists of

multiple separate lodes, two of which are highlighted here; URW1a in purple and URW1b in green. The

remaining URW1 lodes are shown in brown. The main decline is shown in red, the historical exploration

decline in blue, and the grade control drillholes in black.

Zone 5 Grade Control Drilling

The Zone 5 area of the Tuvatu deposit consists of the upper portion of a series of closely spaced lode

systems. The lode systems targeted by the most recent grade control drilling in Zone 5 are the UR1,

UR2, and URW3 lodes. These three lodes are located just east of the historical exploration decline,

strike approximately N-S, and dip sub-vertically to steeply east, similar to the URW1 lodes. As currently

modelled, the UR1, UR2, and URW3 lodes have vertical extents ranging from approximately 700 m to

approximately 900 m, and strike lengths ranging from 300 m to 600 m. All three of the lodes are open

both along strike and at depth.

A total of six Zone 5 grade control drillholes are included in this report. These are the first six grade

control drillholes to target the Zone 5 area and they follow upon the initial results from an ongoing infill drill

program in the area. Figure 5 shows the location of these drillholes in relation to the UR1, UR2, and

URW3 lodes, as well as to the historical exploration decline. Grade control drilling in the Zone 5 area has

been conducted from the historical exploration decline and has been designed to target a 60 m strike

section within the overall 300 m to 600 m strike length of these lodes.

Image shows the

Zone 5 grade control holes in relation to the targeted UR1, UR2, and URW3 lodes. These lodes are

slightly concave with URW3 on the inside (left side on image), closest to the exploration decline, and

UR1 on the outside. UR1 is shown in pink, UR2 in green, and URW3 in blue. The historical exploration

decline is shown in bright blue, and the grade control drillholes are partially visible in black within the

circle.
