Lion One Drills 728.56 g/t Gold over 0.7 m, 25
m Below Current Mine Development at Tuvatu
Gold Mine in Fiji
North Vancouver, British Columbia--(Newsfile Corp. - November 18, 2025) -
Lion One Metals Limited
(TSXV: LIO) (OTCQX: LOMLF) ("
Lion One
"
or the
"
Company
") is pleased to report significant new
high-grade gold results from 2,322 meters of underground infill and grade control drilling at its 100%
owned Tuvatu Alkaline Gold Project in Fiji ("
Tuvatu
").
The drilling is focused on the Zone 5 part of the mine and includes two primary target areas: the down-
dip extension of the Zone 5 lodes below levels 1066 and 1084, which are the lowest levels of current
mine development, and the up-dip mineralization from level 1120 up to 1170 in the southern portion of
the mine in proximity to the planned shrink stope on level 1120 (Figure 1).
Drilling was conducted from two near surface underground drill stations. The Company intersected high-
grade mineralization in 22 drillholes, most of which did not exceed 130 m in length. Most of the high-
grade drill intersects are located within 50 m of underground developments, including the headline
intercept of
728.56 g/t over 0.7 m
, which is approximately 25 m below current mine levels. Other high-
grade gold assay results include
279.00 g/t over 0.3 m, 189.99 g/t over 0.3 m, and 164.00 g/t over
0.3 m
. Previous drilling in this part of the mine has returned similarly high-grade results over narrow
widths such as
175.93 g/t over 0.9 m
,
236.00 g/t over 0.4 m
, and
690.22 g/t over 1.2 m
(see press
releases dated October 9, 2025, May 1, 2025, and January 23, 2025 respectively). Due to the proximity
of these drill results to existing workings, most of these drill intercepts are anticipated to be incorporated
into the mine plan in the next three to twelve months.

Zone 5 drilling are the down-dip extension of the Zone 5 lodes below current underground workings, and
the up-dip extension of the Zone 5 lodes above the 1120 level, at the southern part of the mine in
proximity to the 1120 shrink stope development. The yellow dashed square represents the approximate
area of the 1120 shrink stope which is currently in development.

Zone 5 Drilling
The Zone 5 area of Tuvatu is located on the east side of the deposit and includes the principal north-
south and northeast-southwest oriented lode arrays. These lodes are steeply dipping narrow structures
that converge at approximately 500 m depth to form Zone 500, which is believed to be the highest-grade
part of the deposit and is interpreted to be a feeder zone at Tuvatu. The system remains open at depth
with the deepest high-grade (>10 g/t Au) intersects occurring below 1000 m depth.
There are two primary targets for the drilling reported in this news release, the first of which is the down-
dip extension of the Zone 5 lodes below current mine levels in the central part of the mine. Within Zone 5,
the lowest levels of the mine are currently Levels 1084 and 1066. Level 1084 has over 300 m of
development completed along strike, while Level 1066 has just entered development. The down-dip
drilling program was conducted from one underground drill station located off the Main Decline on Level
1082. The program consists of a fan of drillholes drilled on approximately 15 m centers and was
designed to infill a panel of the deposit approximately 100 m wide and 100 m tall. The first batch of holes
from this drill program are included in this release. This area is targeted for mining within the next 6 to 12
months.
The down-dip drill program returned numerous high-grade drill intersects over narrow widths, such as
728.56 g/t over 0.7 m, 279.00 g/t over 0.3 m, and 70.2 g/t over 1.0 m. These types of narrow intersects
are typical at the Tuvatu deposit as the mineralized structures tend to be quite narrow. However, the
structures also pinch and swell along strike and as a result there are some larger high-grade intervals
that are also returned, such as 3.0 m of 32.29 g/t gold. The drillholes reported here were designed to
intersect the mineralized lodes in a perpendicular to sub-perpendicular orientation such that the
mineralized intervals approximate the true width of the mineralization. Highlights of the Zone 5 down-dip
drill program included in this release are shown in Figure 2.

(levels 1084 and 1066) shown in pale grey. The drill holes shown here targeted the down-dip extension
of the Zone 5 lodes below the lowest levels of current mine development on levels 1084 and 1066. Most
high-grade intercepts are within 50 m of current underground mine development and are scheduled for
mining in the next 6-12 months.

The second major target area for the Zone 5 drilling reported here is the up-dip mineralization from Level
1120 up to and above Level 1170. Similar to the down-dip drill program, high-grade drill intervals in this
drill program typically occur over narrow widths, with some larger intervals >1 m in length.
The Level 1120 up-dip drill program was conducted from one underground drill station located off the
Main Decline on Level 1160. The program consists of a fan of drillholes drilled on approximately 15 m
centers designed to infill a panel of the deposit approximately 150 m wide and 58 m tall. This drill
program is ongoing and is primarily targeting mineralization within the planned 1120 shrink stope, which
is based on Level 1120 and extends up above Level 1150 towards Level 1170.
Development of the 1120 Shrink Stope has already begun, and this drill program is designed to provide
additional information in advance of mining. The Company's first shrink stope was recently completed in
Zone 2, and achieved consistent mining widths of 1.2 m to 1.5 m. Highlights of the 1120 up-dip drill
program are included in Figure 3 and includes numerous high-grade drill results over narrow widths,
such as 93.33 g/t over 0.7 m and 164.00 g/t over 0.3 m (Figure 2). This drill program is ongoing.

Note on Composite Grades
The drill holes reported in this news release are oriented approximately perpendicular to mineralization.
The reported intercepts therefore approximate the true width of mineralization. The minimum mining
width at Tuvatu is approximately 1.5 m. In reporting drillhole intercepts Lion One uses a grade composite
cut-off of 3 g/t gold with <1 m internal dilution at <3 g/t. Drill hole intervals that are <3 g/t are below cutoff
and are not included in Table 2.
Competent Person's Statement
In accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-
101"), Melvyn Levrel, MAIG, Senior Geologist for Lion One Metals, is the Qualified Person for the
Company and has reviewed and approved the technical and scientific content of this news release.
Lion One Laboratories / QAQC
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 diamond drill rigs using PQ, HQ and NQ sized drill rods. The Lion
One geochemical laboratory is accredited under the IANZ ISO/IEC 17025:2017 Standard - the
international standard for testing and calibration of laboratories.
Diamond drill core samples are logged by Lion One personnel on site. Exploration diamond drill core is
split by Lion One personnel on site, with half core samples sent for analysis and the other half core
remaining on site. Grade control diamond drill core is whole core assayed. Core samples are 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 10.00 g/t Au are re-analyzed by gravimetric method, which is
considered more accurate for very high-grade samples.
Duplicates of 5% of samples with grades above 0.5 g/t Au are 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 29 important pathfinder elements with an aqua regia digest and ICP-OES finish.
