Lion One Metals Limited reported successful mining results and better than expected grades from underground developments at its 100% owned Tuvatu Alkaline Gold Project in Fiji. Face sampling on the URW1a lode returned 19.91 g/t Au over the first 35 m of mining, while face sampling on the URW1b lode returned 9.60 g/t Au over the First 22.5 m of mining. The URW1 lode system was originally modelled as a single lode with average grade of 14.05 g/t Au.

The grade from the URW1a lodes is therefore stronger than anticipated while the grade from the URW1b lodes represents additional upside. Highlights of Face Sampling Results: 43.49 g/t Au over 2.1 m (including 61.67 g/t Au over 1.40m) (1140.URW1.NTH.OD-A_17). 34.33 g/t Au over 2.4 m (including 56.56 g/t Au over 1.10m) (1140.URW1.NTH.OD-A_12).

37.00 g/t Au over 2.0 m (including 56.01 g/t Au over 1.32m) (1140.URW1.NTH.OD-A_11). 31.62 g/t Au over 2.33 m (including 50.88 g/t Au over 0.63m) (1140.URW1.NTH.OD-A_16). 34.61 g/t Au over 2.1 m (including 52.81 g/t Au over 1.30m) (1140.URW1.NTH.OD-A_13).

31.52 g/t Au over 2.0 m (including 246.79 g/t Au over 0.23m) (1140.URW1.NTH.OD-A_02). 31.90 g/t Au over 1.9 m (including 60.23 g/t Au over 0.50m) (1140.URW1.NTH.OD-A_08). 25.61 g/t Au over 2.0 m (including 66.4 g/t Au over 0.75m) (1140.URW1.NTH.OD-A_01).

17.32 g/t Au over 1.96 m (including 25.42 g/t Au over 0.31m) (1140.URW1.NTH.OD-B_07). 16.09 g/t Au over 2.0 m (including 35.20 g/t Au over 0.52m) (1140.URW1.NTH.OD-B_11). 12.41 g/t Au over 2.2 m (including 30.50 g/t Au over 0.60m) (1140.URW1.NTH.OD-B_15).

15.77 g/t Au over 1.73 m (including 48.51 g/t Au over 0.36m) (1140.URW1.NTH.OD-B_17). Location of the URW1a and URW1b lodes in relation to the Tuvatu system. Mining is progressing north along both the URW1a lode (modelled in purple) and the URW1b lode (modelled in green).

Inset image shows the location of the URW1a and URW1b lodes in relation to the Tuvatu system, with all other lodes shown in pale grey. Underground developments are shown in red. The URW1 mineralized trend has a N-S strike length of approximately 300 m and a vertical extent also of approximately 300 m. The URW1a and URW1b lodes occupy approximately 75m of this mineralized strike length.

Extensional drilling is ongoing. Plan map showing the location and face grades returned from face sampling in URW1a and URW1b. The URW1a mining drive is on the left and the URW1b mining drive is on the right.

Face grades in g/t Au and their corresponding sample numbers are shown in white. The locations of the face samples are indicated by the sub-horizontal lines. Grid lines are 10 m apart.

Mining is ongoing and progressing to the north. Mining of the URW1 lodes has been ongoing since May 18th, 2023, and is being conducted through the use of airleg mining. Mining is progressing in a step-wise fashion with the mining drives advancing in increments of 2 m. Prior to blasting, a face sample is collected across the face of the advancing drive, with the sample being oriented approximately perpendicular to the strike of the mineralized lode.

These samples lines are typically around 2 m in length and traverse the entire width of the drive such that they represent all the material mined and not just the main lode. The face samples are therefore considered representative of the grade at the face of the advancing drive and provide an indication of the grade of the material extracted with each blast. The series of face samples collected progressively along the strike of the lode provide an estimate of the grade of the material mined from the lode to date.

Due to the nature of mineralization at Tuvatu there is local variation in gold grades, and the more extensive the systematic sampling is the more accurate the depiction of the overall grade and gold content of each lode will be.
