Infill Drilling Program
Multiple bonanza-grade intercepts have been returned from the ongoing near-surface infill/definition drill program which is aimed at a thorough re-appraisal of the database in portions of the resource earmarked for earliest production. The current ~8000m infill drill program was initiated in June of 2021 with the aim of infilling areas of low data density within parts of the resource currently categorized as Inferred. To date, a total of ~6735m of diamond drilling over 38 holes have been completed, with ~15% of the proposed program remaining. Final results are here reported from a total of 10 holes, 7 of which were drilled specifically as part of the infill program (TUDDH555-562, 565) and three of which were drilled as part of the deep program testing the 500 Zone, but which intersected high grade mineralization in the near-surface (TUDDH563, TUG136, 137). Figures 1-3 illustrate schematically the location of drill holes reported here, and mineralized intervals relative to modelled lodes.

The exceptional grades returned from hole TUDDH565 at a downhole depth of ~71.2m, of 1616.0 g/t Au corresponds to a complex vein of centimetric width at low to moderate angle to core axis, consisting of coarse, subhedral honey sphalerite, fine skeletal marcasite and coarse visible gold in a groundmass of amorphous gray quartz. The vein also contained coarse vugs lined by clear crustiform euhedral quartz crystals and abundant delicate wire native gold. Figures 4 and 5 show some of the coarse visible gold intersected at this interval as well as other mineralogical characteristics. A complete set of results for all near-surface drill intersections reported here is included as Table 1; drill hole parameters are included as Table 2. Results from deeper drill intersections will be reported in a subsequent news release.

The Company is currently undertaking two tiers of drilling: 1) the completion of shallow resource infill drilling from surface and underground, 2) deep exploration drilling from surface and underground targeting lode extensions and additional feeders under the Tuvatu resource. Regional drill programs requiring access to remote parts of the Navilawa caldera has been interrupted during the wet season, but will resume in early 2022.

Sergio Cattalani, Lion One's Senior Vice President Exploration, commented, "Exceptionally high grade mineralization has been defined in the near-surface portion of the deposit. High grade mineralization is showing to be more consistent and appears to form wider zones with good continuity than what had been previously modelled. I am increasingly confident that once underground mining is underway, the average head grade of the ore earmarked for early production will be higher than previously modelled. The additional data generated by the infill drilling and resampling programs currently underway are indicating that portions of the orebody return higher grades over multiples of minimum mining widths that are not defined by the current resource model.

Our objective remains clear: to work toward a near-term modest production start, concomitant with an aggressive exploration program aimed at the continued expansion of bonanza-grade resources both near-surface and along defined feeder conduits at greater depths, for the eventual scaled-up development of a larger and more valuable resource."

Right) Plan view of Tuvatu orebody as a block model, showing the trace of the Tuvatu decline and the location of the vertical section on the left. The different colors represent ore blocks of different grade forming the various lodes. Note that many of the mineralized intervals do not correspond with the previously modelled lodes, suggesting the possibility of previously unrecognized mineralization.

Drilling and Assay Processes and Procedures
The Company is utilizing its own diamond drill rig, using PQ, HQ and ultimately NQ sized drill core rods. Drill core is logged by Company geologists and then is sawn in half and sampled by Lion One staff.

Samples are analyzed at the Company's own geochemical laboratory in Fiji, whilst pulp duplicates of all samples with results >0.5g/t Au are re-assayed, as well as sent to ALS Global Laboratories in Australia for check assay determinations. All samples for all high-grade intercepts reported here are will be sent to ALS Global Laboratories for check assays shortly. All samples are pulverized to 80% passing through 75 microns. Gold analysis is carried out using fire assay with an AA finish. Samples that have returned grades greater than 10g/t Au are then re-analyzed by gravimetric method. For certain high-grade samples for which results for duplicate assay are within 10% of the initial results, the average of duplicate runs is presented. 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 sent to ALS Townsville, Queensland, Australia are analyzed by the same methods (Au-AA26, and also Au-GRA22 where applicable). ALS also analyze for 33 pathfinder elements by HF-HNO3-HClO4 acid digestion, HCl leach and ICP-AES. (method ME-ICP61).
