North Vancouver, British Columbia--(Newsfile Corp. - May 1, 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 4,123.8 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 deposit, which is currently being mined.

Drilling was conducted from two near surface underground drill stations. The Company intersected high-grade mineralized structures in 29 drill holes targeting the UR2 lode down-dip of current underground developments. Most of the drill holes did not exceed 150 m in length and most of the high-grade drill intercepts are located within 50 m of current underground workings. Drill results include multiple bonanza grade gold intercepts over narrow widths, such as 236.00 g/t over 0.4 m, 101.58 g/t over 0.5 m, 102.35 g/t over 0.3 m, 94.23 g/t over 0.3 m, and 89.63 g/t over 0.4 m. Due to the proximity of 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.

Tuvatu is a high-grade narrow vein alkaline gold deposit and bonanza grade drill results are not uncommon on the project. In January the Company released the highest grade assay ever returned from Zone 5 drilling; 2,749.86 g/t over 0.3 m (see press release dated January 23, 2025). Previous high-grade drill results from Zone 5 include 1,517.79 g/t gold over 0.3 m (see press release dated December 17, 2024), 1,568.55 g/t over 0.3 metres (see press release dated June 5, 2024), and 1,986.23 g/t gold over 0.6 m (see press release dated December 13, 2023).

Highlights of New Drill Results:

• 236.00 g/t Au over 0.4 m (TGC-0345, from 109.42 m depth)
• 25.89 g/t Au over 3.0 m (including 101.58 g/t Au over 0.5 m g/t) (TGC-0359, from 110.7 m depth)
• 16.85 g/t Au over 3.0 m (including 38.27 g/t Au over 0.9 m) (TGC-0339, from 104.7 m depth)
• 18.26 g/t Au over 2.5 m (including 89.63 g/t Au over 0.4 m) (TGC-0332, from 67.14 m depth)
• 15.36 g/t Au over 2.7 m (including 47.25 g/t Au over 0.3 m) (TGC-0343, from 75.3 m depth)
• 27.08 g/t Au over 1.5 m (including 94.23 g/t over 0.3 m) (TGC-0343, from 61.7 m depth)
• 16.34 g/t Au over 2.3 m (including 23.57 g/t over 0.6 m) (TGC-0335, from 102.1 m depth)
• 29.44 g/t Au over 1.3 m (including 102.35 g/t Au over 0.3 m) (TGC-0347, from 108.96 m depth)
• 25.96 g/t Au over 1.4 m (including 43.58 g/t Au over 0.6 m) (TGC-0343, from 68.9 m depth)
• 14.23 g/t Au over 2.4 m (including 23.37 g/t Au over 0.4 m) (TGC-0327, from 101.9 m depth)

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

Zone 5

The Zone 5 area of Tuvatu is located along the main decline and includes the principal north-south and northeast-southwest oriented lodes at Tuvatu, as well as several western lodes. These lodes are steeply dipping structures that converge at approximately 500 m depth to form Zone 500, which is the highest-grade part of the deposit and is interpreted to be a major feeder zone at Tuvatu. The system remains open at depth with the deepest high-grade intersections occurring below 1000 m depth.

The drilling reported in this news release targeted the near-surface portion of the UR2 lode down-dip of current underground developments. The UR2 lode is one of the main north-south oriented lodes at Tuvatu. It has a strike length of approximately 600 m and dips steeply to the east. Mine development is currently taking place along the UR2 lode at the 1100 and 1102 levels of the mine, which are the deepest levels in Zone 5, as well as at the 1134 level of the mine. The drilling reported here was conducted from two underground drill stations; the 1090 drill station and the 1135 drill station. Drilling from the 1090 drill station targeted a 60 m wide section of the UR2 lode between 30 m and 50 m below the 1100 level at the south end of the lode. Drilling from the 1135 drill station targeted a 100 m wide section of the UR2 lode approximately 10 m above and 10 m below the 1102 level in the middle portion of the lode.

The UR2 drill program consists of infill and grade control drilling with the purpose of providing a detailed understanding of the geometry and mineralization of the UR2 lode in advance of mining. Drilling is being conducted on 10 m centers. 29 out of the 32 drill holes reported in this news release intersected high-grade mineralization. Most of the high-grade intervals reported in this release are located within 50 m of underground developments and are anticipated to be included in the mine plan in the next 6 to 12 months. One additional hole (TGC-0311) was drilled to test a deeper portion of the UR2 lode and returned several high-grade intercepts approximately 80 m below the 1102 level. Highlights of the Zone 5 drilling reported here are shown in Figure 2.

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. Tuvatu consists of high-grade narrow vein mineralization. The headline intercept of 236.00 g/t gold over 0.4 m therefore has an approximate true width of 0.4 m, as reported. 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.

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 26 important pathfinder elements with an aqua regia digest and ICP-OES finish.
