LIO:CC - Lion One Drills 78.71 g/t Gold over 2.0 m, Including 168.25 g/t Gold over 0.9 m at Tuvatu Gold Mine in Fiji

North Vancouver, British Columbia--(Newsfile Corp. - October 9, 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 4,180.5 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 area of the mine, down-dip of current mine levels.

All drilling was conducted from near surface underground workings. The Company intersected high-grade mineralized structures in 24 holes up to 100 m below current underground workings. The primary target for the drilling was the down-dip extension of the Zone 5 lodes below the current mine levels. Most of the high-grade drill intercepts are located within 60 m of current underground workings, and include multiple very high-grade gold assays, such as 267.95 g/t over 0.3 m, 168.25 g/t over 0.9 m, 179.52 g/t over 0.3 m, 126.49 g/t over 0.5 m, and 175.52 g/t over 0.4 m. Previous drilling in this part of the mine has returned similarly high-grade results, including the highest intercept ever recorded at Tuvatu - 2,749.86 g/t over 0.3 m (see press release dated January 23, 2025). Due to the proximity of these drill results to existing workings there is a strong probability that these intercepts can be incorporated into the mine plan in the next six to twelve months.

Highlights of New Drill Results:

• 175.43 g/t Au over 0.9 m (including 267.95 g/t Au over 0.3 m) (TGC-0451, from 89 m depth)
• 78.71 g/t Au over 2.0 m (including 168.25 g/t Au over 0.9 m) (TGC-0383, from 69.7 m depth)
• 29.70 g/t Au over 3.1 m (including 179.52 g/t Au over 0.3 m) (TGC-0406, from 83.2 m depth)
• 30.50 g/t Au over 2.7 m (including 45.78 g/t Au over 0.7 m) (TGC-0424, from 85.9 m depth)
• 51.35 g/t Au over 1.5 m (including 126.49 g/t Au over 0.5 m) (TGC-0379, from 89.5 m depth)
• 56.59 g/t Au over 1.3 m (including 62.39 g/t Au over 0.9 m) (TGC-0447, from 92 m depth)
• 175.52 g/t Au over 0.4 m (TGC-0387, from 67.1 m depth)
• 52.18 g/t Au over 1.1 m (including 86.25 g/t Au over 0.5 m) (TGC-0373, from 157.8 m depth)
• 16.19 g/t Au over 2.2 m (including 84.47 g/t Au over 0.3 m) (TGC-0414, from 74.9 m depth)
• 96.48 g/t Au over 0.4 m (TGC-0383, from 212.5 m depth)
• 12.83 g/t Au over 2.5 m (including 69.57 g/t Au over 0.3 m) (TGC-0451, from 99.0 m depth)
• 8.37 g/t Au over 3.6 m (including 17.91 g/t Au over 0.7 m) (TGC-0449, from 128.0 m depth)

*Drill intersects are downhole lengths, 3.0 g/t cutoff. True width not known. See Table 1 for additional data.

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 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.

The drilling reported in this news release targeted the down-dip extension of the Zone 5 lodes below current mine levels. All the drilling was conducted from one underground drill station and consisted of a fan of drillholes drilled on 15 m centers that was designed to infill a panel of the deposit approximately 130 m wide and 100 m tall. This area is targeted for mining within the next 6 to 12 months and represents an additional five levels of mining at Tuvatu.

The drillholes reported in this news release include multiple very high-grade gold assays over narrow widths, such as 267.95 g/t over 0.3 m, 168.25 g/t over 0.9 m, 179.52 g/t over 0.3 m, 126.49 g/t over 0.5 m, and 175.52 g/t over 0.4 m. These types of intersects are typical at Tuvatu as the deposit consists of high-grade narrow vein structures. 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. The purpose of the Zone 5 drill program is to enhance the mine model and inform stope design in advance of mining the target areas. Highlights of the Zone 5 drilling reported here are shown in Figure 2.

The drill holes shown here primarily targeted the down dip extension of the Zone 5 lodes below current underground workings shown in red. This area is targeted for mining within the next 6 to 12 months.

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.
