Lion One Metals Limited Reports Significant New High-Grade Gold Results from Ongoing Grade Control Drilling at its 100% Owned Tuvatu Alkaline Gold Project in Fiji
Lion One Metals Limited reported significant new high-grade gold results from ongoing grade control drilling at its 100% owned Tuvatu Alkaline Gold Project in Fiji. Assay results are presented here for grade control drilling completed in the Zone 2 area of Tuvatu, focusing primarily on the URW1, URA1 and Murau lode systems. Mining of the URA1 lode and the URW1 lode system is ongoing and grade control drilling is being conducted in advance of future mining in these areas. The results reported here represent material that is scheduled to be mined in Fourth Quarter 2023 and throughout 2024. Highlights of new Zone 2 grade control drilling (3 g/t Au cutoff): 19.78 g/t Au over 6.0 m (including 31.52 g/t Au over 3.0 m) (TGC-0071, from 114.0 m depth); 14.83 g/t Au over 6.0 m (including 25.16 g/t Au over 2.4 m) (TGC-0055, from 90.9 m depth); 18.08 g/t Au over 3.6 m (including 32.74 g/t Au over 1.5 m) (TGC-0073, from 90.0 m depth); 25.25 g/t Au over 2.4 m (including 149.63 g/t Au over 0.3 m) (TGC-0078, from 95.2 m depth); 45.89 g/t Au over 0.9 m (TGC-0080, from 23.4 m depth); 8.00 g/t Au over 4.8 m (including 21.05 g/t Au over 0.9 m) (TGC-0080, from 47.4 m depth); 8.52 g/t Au over 3.3 m (including 11.16 g/t Au over 1.8 m) (TGC-0053, from 13.8 m depth); 17.73 g/t Au over 1.5 m (including 20.98 g/t Au over 0.9 m) (TGC-0053, from 56.4 m depth); and 14.13 g/t Au over 1.8 m (including 18.64 g/t Au over 1.2 m) (TGC-0062, from 67.5 m depth). Zone 2: The Zone 2 area of Tuvatu is located in the northwest part of the system along the western decline. It is the first part of the deposit scheduled for mining and encompasses a number of distinct lode systems, including the URW1, URA1, and Murau lode systems. The URW1 lode system was the primary target for the current round of drilling. It consists predominantly 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. Current modelling suggests that there are multiple separate lodes within the URW1 lode system. The first two of these lodes, URW1a and URW1b, are currently being mined. As reported on July 13, 2023 and July 27, 2023, mineralization in these lodes is both higher grade and more laterally extensive than initially anticipated. Grade control drilling in the URW1 area is targeting the up-dip and down-dip extensions of these lodes, 20 m to 40 m above and below the current mine drives. The URW1 lode system has a current strike length of approximately 300 m in the N- S direction, and a vertical extent of approximately 300 m. Similarly, the URA1 lode is a narrow, steeply dipping, high-grade to locally bonanza-grade vein system. It was discovered during the development of the western decline and is intersected by the decline at approximately 75 m from the portal entrance. It trends approximately northeast-southwest and dips steeply to the southeast. It has a current strike length of approximately 100 m, and a vertical extent of approximately 120 m. The Murau lode system consists of a series of stacked relatively flat lying lodes that strike approximately east-west and dip moderately to the south. Mining is scheduled to begin on the upper part of the Murau lode system in Fourth Quarter 2023. The portion of the Murau lode system that is currently targeted for mining consists of a 110 m strike length in the east-west direction, a vertical extent of 55 m, and a down-dip extension of 100 m. Grade Control Drilling: Grade control drilling is being conducted from underground as well as from near the mine portal and is targeting near surface mineralization scheduled for mining in the next four to sixteen months. It is targeting 5-10 m centers and is designed to provide a detailed understanding of the geometry and mineralization of lode arrays in advance of underground development. Results from the grade control drill program will be used to help optimize mine development and mineral extraction in these areas. The Zone 2 grade control drill program is ongoing. Examples of mineralization observed in the Zone 2 drillholes reported. A total of 83 grade control drillholes have been completed to date in the Zone 2 and Zone 5 areas at Tuvatu, including 24 grade control drillholes included in this news release. Previous grade control drill results are available in the news releases dated April 25, 2023 and June 14, 2023. 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).
