Lion One Announces New Regional Gold Discovery 2 km Northeast of Tuvatu Alkaline Gold Project in Fiji

North Vancouver, British Columbia--(Newsfile Corp. - August 29, 2022) - Lion One Metals Limited (TSXV: LIO) (OTCQX: LOMLF) (ASX: LLO) ("Lion One" or the "Company") is pleased to announce a new regional high grade gold discovery, the Batiri Creek Vein, located in the Navilawa Caldera 2 km northeast of the Company's 100% owned, fully permitted Tuvatu Alkaline Gold Project in Fiji.

The Batiri Vein discovery is credited to the Lion One Fiji exploration team's regional benching and surface sampling program targeting new gold bearing systems in under-explored regions peripheral to Tuvatu in the surrounding Navilawa Caldera.

The new structure is characterized by an intense zone of veining on a lithological contact between monzonite and andesite, with two significant N-S and NE-SW oriented structural intersections. The lithological contact and structural intersections observed in the Batiri Vein are comparable to the lithological contact and structural intersections observed from deep extensional drilling in the 500 Zone below the Tuvatu resource where Lion One recently reported the longest and highest-grade intercepts yet recovered at Tuvatu, including 20.86 g/t Au over 75.90m from TUG 141 (see NR dated June 6, 2022) and 12.22 g/t Au over 54.90m including 20.10m @ 23.03 g/t Au from TUDDH 601 (see NR dated Aug. 15, 2022).

Highlight intercepts from surface benching/channel sampling program include:

Surface Channel: Batiri Vein (CH3047-CH3048)

• 13.27g/t Au over 4.0m at surface including:
  • 36.10 g/t Au over 1.0m and
  • 17.91 g/t Au over 0.80m

Other results from the Batiri Vein include:

• Channel CH2765 with 2.63g/t Au over 1.0m
• Channel CH2834 with 3.32g/t Au over 0.3m
• Channel CH2789 with 3.54g/t Au over 0.3m
• Channel CH2946 with 3.42g/t Au over 0.4m
• Channel CH3073 with 3.32g/t Au over 1.0m

Lion One is planning a regional drill program for the Batiri Vein target. The Company now has eight drill rigs, with the pending delivery of the latest two rigs expected around mid-September. The Company currently has two drilling programs underway, including Zone 5 infill drilling on the Tuvatu resource, and deep extensional drilling in Zone 500 below the Tuvatu resource. The Company has now drilled approximately 6,100 meters, about 75% of the planned infill drilling on Zone 5 and expects to announce the results from previously unreleased holes in the near future.

Lion One technical advisor Quinton Hennigh stated, "Tuvatu and the wider Navilawa Caldera are part of a classic alkaline gold system. As we know, from geologically comparable world class systems, such as Porgera in PNG or Cripple Creek in Colorado, these kinds of deposits are not isolated and there is potential for multiple zones of mineralisation within the gold camp. The new discovery on the Batiri Vein presents the potential for such a new discovery."

Lion One CEO Walter Berukoff further stated, "The new discovery at surface on the Batiri Vein is very encouraging and I congratulate the regional exploration team for their persistence. While the Tuvatu Gold Project is the core of our development, any new discoveries in the immediate vicinity potentially play a part in the development of a high-grade gold mine. We look forward to following this up with drilling in the near future."

QAQC Procedures

Lion One adheres to rigorous QAQC procedures above and beyond basic regulatory guidelines in conducting its channel sampling, drilling, testing, and analyses. For Channel Sampling, Company geologists first map the bench, and then measure and mark-up sample intervals based on geological structure. Samples are delivered to and analysed 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 80% 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-analysed 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. For samples with multiple fire assay runs, 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 are sent to ALS labs in Townsville QLD and are analysed by the same methods (Au-AA26, and Au-GRA22 where applicable). ALS also analyses for 33 pathfinder elements by HF-HNO3-HClO4 acid digestion, HCl leach and ICP-AES (method ME-ICP61).
