Wiluna Mining Corporation Limited announced further high-grade results from resource development drilling at the Wiluna Mining Centre. Results continue to demonstrate that Wiluna is a very large and high-grade ore body. Happy Jack and East Lode are initial mining areas in the Company's two-staged development plan. At Happy Jack, ore drive development on sulphide mineralisation is underway ahead of stoping this quarter. The Company expects to publish its updated Mineral Resource Estimate mid-month. The current high-grade resource at the Wiluna Mining Centre, above a 2.5 g/t cut-off, is 26.9Mt @ 4.90 g/t for 4.23Moz and the historic mined grade was considerably higher at 7g/t to 11 g/t depending on the ore zone. It is considered that with results like these, the mined grade will increase when stoping commences. The latest drilling results comprise an additional 33 holes for 11,723m from Happy Jack and East Lode, received since the preceding drilling update announced on 13 September 2021. Wiluna Mining's drilling program has consistently delivered thick, high-grade intercepts over the past 18 months from targeted locations at shallow depths, and close to previous development that is easily accessible for rapid low-cost production (Figure 1). Infill drilling remains ongoing and is now focussed on Resource infill, Resource extension and grade control programs at the Bulletin and Happy Jack ore bodies. Results from diamond core grade control programs have been broadly in line with Resource development program results. The program was designed primarily to infill areas of Inferred Resource within preliminary stope designs, with the aim to upgrade geological confidence to Indicated Resource category and to grow the Ore Reserve. Additionally, extensional drilling has aimed to extend potential stoping areas along strike, up-dip and down-dip. The program has targeted growth in the Measured and Indicated Resource categories to 2.5Moz, from 2.14Moz @ 5.26g/t currently (>2.5g/t cut-off), to provide the foundation for a sustained long-term mining operation. However, the program also shows potential for Resource growth where holes have intersected the mineralised shear zone outside of the current Inferred and Indicated Resource limits . Wiluna Mining's drilling has focussed on the upper 300m down to 500m below surface, and considerable potential for Resource extensions exists where the lodes remain open in at depth and along strike. Highlights from the current drilling include: HJRD00067: 3.72m @ 5.31g/t, HJRD00075: 3.60m @ 7.22g/t, HJRD00078: 3.53m @ 13.37g/t, HJRD00080: 2.56m @ 5.56g/t incl. 0.30m @ 35.50g/t, WUDD0074: 3.34m @ 10.16g/t.
