Lion One Drills 1517.79 g/t Gold over 0.3 M at Tuvatu Gold Mine in Fiji

North Vancouver, December 17, 2024 - Lion One Metals Ltd. (TSXV: LIO) (OTCQX: LOMLF) ("Lion One" or the "Company") is pleased to report significant new high-grade gold results from Zone 5 infill and grade control drilling at its 100% owned Tuvatu Alkaline Gold Project in Fiji.

Assay results are presented here for infill and grade control drilling in the Zone 5 area of Tuvatu. Drill results include multiple bonanza grade gold assays such as 1517.79 g/t, 513.50 g/t, 113.76 g/t, 137.50 g/t, and 115.25 g/t (see Table 1 below). These results are all located proximal to underground development in the near-surface portion of the mine. Drilling was focused on the up-dip and down-dip areas of the UR2 and URW3 lodes. Previous drill results from the Zone 5 area are available in the June 12, 2024, June 5, 2024, and December 13, 2023 news releases.

Zone 5 Drilling

The Zone 5 area of Tuvatu is located along the main decline and includes the principal north-south oriented lodes (UR1 to UR3), the principal northeast-southwest oriented lodes (UR4 to UR8), and several of the western lodes (URW2, URW2A, URW3). 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 the 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 portions of the UR2 and URW3 lodes. Drilling was focused on the up-dip and down-dip areas of the UR2 and URW3 lodes, directly above and below current underground developments. The drilling targeted a 320 m strike length of the UR2 and URW3 lodes. The current total strike length of the UR2 lode is approximately 620 m, while that of the URW3 lode is approximately 330 m. Both lodes remain open along strike and at depth.

Zone 5 grade control drilling is being conducted from three underground locations: the 1130 drill cuddy, the 1135 drill cuddy, and the 1090 drill cuddy. These drillholes are designed to intersect the mineralized lodes in a perpendicular to sub-perpendicular orientation such that the mineralized intervals approximate the true width of the lodes. Grade control drilling is being conducted on 10 m centers to provide a detailed understanding of the geometry and mineralization of the Zone 5 lodes. The purpose of the current Zone 5 grade control drill program is to enhance the mine model and inform stope design in advance of mining in the target areas. Highlights of the Zone 5 drilling reported here are shown in Figure 2.

The primary areas targeted by the Zone 5 drilling are the up-dip and down-dip areas of the UR2 and URW3 lodes above and below current underground developments. These areas are scheduled for near-term mining. Drill holes are oriented perpendicular to sub-perpendicular to the mineralized lodes.

Competent Persons Statement

The information in this report that relates to mineral exploration at the Tuvatu Gold Project is based on information compiled by the Lion One team and reviewed by Melvyn Levrel, who is the company's Senior Geologist. Mr Levrel is a Member of the Australian Institute of Geoscientists and has sufficient experience that is relevant to the style of mineralisation and type of deposit under consideration, and to the activity being undertaken, to qualify as a Qualified Person as defined by National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43- 101"). Mr Levrel consents to the inclusion in this report of the matters based on the information in the form and context in which it appears.

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.

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