Lion One Reports New High-grade Gold Results at Tuvatu

North Vancouver, British Columbia--(Newsfile Corp. - April 25, 2023) - Lion One Metals Limited (TSXV: LIO) (OTCQX: LOMLF) (ASX: LLO) ("Lion One" or the "Company") reports significant new high-grade results from grade control drilling at the Company's 100% owned Tuvatu Alkaline Gold Project in Fiji.

Following on the initial mining and extraction of the URA1 lode, the Company is here reporting new high-grade results from grade control drilling on the URW1 lode system, approximately 120m further east. Mining of URW1 is expected to begin over the next 2-4 weeks. Strike drive development on URW1 has commenced.

Highlights of new high-grade gold mineralization intersected by grade control drilling:

• Multiple bonanza grade zones have been intersected including:
  • 88.07g/t Au over 5.7m (including 1,396g/t Au over 0.3m) (TGC-0034)
  • 27.52g/t Au over 5.55m (TUG-056)
  • 20.93g/t Au over 7.2m (TGC-0003)
  • 16.12g/t Au over 9.3m (TGC-0014)
  • 16.48g/t Au over 9.6m (TGC-0002)
  • 14.6g/t Au over 6.6m (TGC-0032)
  • 14.97g/t Au over 5.4m (TGC-0018)
  • 10.85g/t Au over 6.9m (TGC-0013)
• Visible was gold observed in several drill holes.

Close spaced grade control drilling has resulted in much higher resolution of the lode arrays as compared to previous infill drilling, including the identification of bonanza grade (>50g/t Au) zones.

The tightened drill pattern will facilitate optimised development and extraction of high-grade gold mineralization from the URW1 lodes while minimizing dilution. High-grade gold mineralization extracted from the URW1 lode system will contribute significantly to the growing high-grade stockpile constituting the initial feed for the Company's plant and processing facility, on schedule for start-up in Q4 2023.

Mineralization
Mineralization consists of abundant free gold, typically in association with light to dark gray chalcedonic quartz and roscoelite, locally accompanied by minor amounts of pyrite, sphalerite, galena and lesser chalcopyrite (Figure 3).

URW1 Lode System
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 and is located approximately 120m east of the URA1 lode (Figure 1, 2, 4).

As currently modelled based on earlier drilling, the URW1 lode measures approximately 300m in the NS-direction by approximately 300m of vertical extent, thus forming one of the major N-S trending lodes that have been recognized in this part of the Tuvatu deposit. The URW1 lode intersects with numerous flat-lying to moderately south-dipping EW veins referred to as the Murau lode system (Figure 4).

Grade control drilling has been conducted from both the new decline and the historic exploration adit (Figures 1 & 2). This drilling is targeting a 60m strike section of the URW1 system, within the >300m strike of the overall URW1 system. Detailed drilling of this nature is the first conducted at the project and has served to confirm both the location of structures and the extent of some of the higher-grade zones within the overall mineralized envelope. These bonanza zones (>50g/t Au * true width) have been intersected that show a considerably higher-grade than the previous wide-spaced resource drilling in the area. The high-grade zones are interpreted to relate to the intersection of the N-S URW1 lode with E-W striking structures such as the Murau lodes.

The URW1 lode system is interpreted as a series of parallel vein arrays.

This interpretation has come by way of a series of closely spaced grade control drill holes, drilled from two separate locations, east-directed drilling from the main decline, as well as west-directed drilling from the exploration decline (Figure 1). To date, a total of 34 diamond drill holes totalling approximately 3538m have been completed resulting in 5m to 10m spacing between adjacent holes covering a limited extent of the URW1 lode system. Despite the relatively limited size of the area drilled thus far, the grade control program has significantly increased the level of confidence in the geometry, widths, and grade distribution of the URW1 lodes, thereby allowing for detailed development planning.

Composited assay results for mineralized intervals interpreted as URW1 lodes in holes completed to date are presented in Table 1, with Tables 2 and 3 in the appendix containing full drill hole details. The URW1 lode system represents the next main area of mining and extraction of high-grade mineralization at Tuvatu. Development has commenced with first grade control and mapping expected shortly.

Au) and 1,325,000 tonnes inferred at 9.0 g/t Au (384,000 oz. Au) at a cut-off grade of 3.0 g/t Au. The technical report is available on the Lion One website at www.liononemetals.com and on the SEDAR website at www.sedar.com.

Qualified Person
In accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43- 101"), Sergio Cattalani, P.Geo, Senior Vice President Exploration, is the Qualified Person for the Company and has reviewed and is responsible for the technical and scientific content of this news release.

QAQC Procedures
Lion One adheres to rigorous QAQC procedures above and beyond basic regulatory guidelines in conducting its sampling, drilling, testing, and analyses. The Company utilizes its own fleet of diamond drill rigs, using PQ, HQ and NQ sized drill core rods. Drill core is logged and split by Lion One personnel on site. Samples are delivered to and analyzed at the Company's geochemical and metallurgical laboratory in Fiji. Duplicates of all samples with grades above 0.5 g/t Au are both re-assayed at Lion One's lab and delivered to ALS Global Laboratories in Australia (ALS) for check assay determinations. All samples for all high-grade intercepts are sent to ALS for check assays. All samples are pulverized to 85% passing through 75 microns. Gold analysis is carried out using fire assay with an AA finish. Samples that have returned grades greater than 10.00 g/t Au are then re-analyzed by gravimetric method. For samples that return greater than 0.50 g/t Au, repeat fire assay runs are carried out and repeated until a result is obtained that is within 10% of the original fire assay run. Lion One's laboratory can also assay for a range of 71 other elements through Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES), but currently focuses on a suite of 9 important pathfinder elements. All duplicate anomalous samples are sent to ALS labs in Townsville QLD and are analyzed by 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).
