Lion One Starts Mechanized Production at Tuvatu, Drills 1.2 M of 393.01 g/t Gold

North Vancouver, British Columbia–(Newsfile Corp. – June 5, 2024) – Lion One Metals Limited (TSXV: LIO) (OTCQX: LOMLF) (ASX: LLO) (“Lion One” or the “Company”) is pleased to report the start of mechanized production at Tuvatu and reports significant new high-grade gold results from Zone 5 infill and grade control drilling at its 100% owned Tuvatu Alkaline Gold Project in Fiji.

Mechanized production mining has commenced at Tuvatu. The first remote bogging at Tuvatu occurred on May 16th, and the first long hole stope blast occurred on May 18th. Both are also firsts for the country of Fiji. This is a major milestone for the company as it represents the transition from predominantly development mining to predominantly production mining. The processing plant can now also sustainably process over 400 TPD, which is above the plant’s name plate capacity of 300 TPD. The increased throughput is possible due to the successful implementation of operational improvements and debottlenecking initiatives completed by the mill team.

Assay results are also 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 1568.55 g/t, 215.86 g/t, 143.95 g/t, and 134.68 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 two locations; to the north and south of the Cabex fault, which is a carbonate healed, deposit scale structure. The primary targets for these drillholes were the downdip and southern extensions of the UR2 and URW3 lodes. Previous drill results from the Zone 5 area are available in the December 13, 2023November 2, 2023, and August 10, 2023 news releases.

Highlights:

  • First mechanized production mining at Tuvatu
  • First ever remote bogging at Tuvatu on May 16th
  • First ever long hole firing at Tuvatu on May 18th
  • Mill operations increased from 300 TPD to 400 TPD
  • Top new drill intersects:

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 the 500 Zone, 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 intersects occurring below 1000 m depth.

The drilling reported in this news release was focused on the near-surface portions of the UR2 and URW3 lodes. These areas are scheduled to be mined throughout the next 12 months. Drilling was separated into two focus areas; to the north of the Cabex Fault, and to the south of the Cabex Fault. The Cabex Fault is a post-mineralization fault that strikes approximately ESE and dips approximately 65° to the SSW. It is interpreted to be a late caldera collapse structure that is healed with carbonate.

The purpose of the Zone 5 infill and grade control drill program is to enhance the mine model and inform stope design in advance of mining. Drilling to the north of the Cabex primarily targeted the down dip extension of the UR2 lode below the 1120 level. Drilling to the south of the Cabex targeted both the down dip extensions of the UR2 and URW3 lodes below the 1100 level, as well as the southern extension of the lodes above and below the 1120 level. Highlights of the Zone 5 drill program are shown in Figure 2 and Figure 3.

Operations Update

Mechanized production mining is underway at Tuvatu. The two remote-capable loaders on site are now fully commissioned and in operation. The first ever remote bogging activity at Tuvatu occurred on May 16th at the 1120 level south, on the UR2 lode in Zone 5. Remote loaders are necessary to extract material from open stopes after blasting. The two long hole drills on site are also fully commissioned and in operation. The first ever long hole production blast at Tuvatu occurred on May 18th, blasting level to level via long holes from the 1120 level north to the 1130 level north, also on the UR2 lode in Zone 5. Both the first remote bogging activity and the first long hole production blast at Tuvatu are major milestones for the company as they represent the start of mechanized production mining. They are also both firsts for the country of Fiji as this style of mining has not taken place in Fiji until now.

Mill operations are also advancing successfully. Operational improvements and debottlenecking projects completed by the mill operations team have successfully increased throughput at the mill. These bottlenecking projects include upgrading the process water recycle system, upgrading the thickener pumps and piping, and reducing the tailings filter press cycle times. As a result of these upgrades the processing plant can now achieve a sustained throughput of over 400 TPD, with peak daily throughput of over 450 TPD. The name plate capacity of the processing plant during the ongoing pilot plant stage of operations is 300 TPD. These upgrades therefore represent a substantial improvement in the processing capacity available at Tuvatu.

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 Alex Nichol, who is the company’s Vice President of Geology and Exploration. Mr Nichol 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 Competent Person as defined in the 2012 edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’ (JORC code). Mr Nichol 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 and split by Lion One personnel on site and 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.
