Wiluna Mining Corporation Limited announced this geology update, including outstanding results of 0.30m @ 3,270g/t and 1.50m @ 8.30g/t within a broader zone of 10.00m @ 2.80g/t, from the Company's very first hole testing the Bulletin North Discovery target. The Bulletin North target is one of nine large-scale sulphide shoot targets to be tested as part of a 40,000m discovery program across the Wiluna mine site. Further, high-grade results from resource development and grade control drilling at Bulletin and Happy Jack zones support geology modelling and the short-term production profile in immediate mining areas during the ramp-up in sulphides concentrate production.

The Company's 1,600km2 exploration tenure in the broader Wiluna region is also geologically prospective for lithium pegmatites and nickel-copper-cobalt-platinum group element (Ni-Cu-Co-PGE) mineralisation. Grass-roots exploration has commenced with a review of historical geophysical and geological datasets and identification of initial targets that require follow-up field work. The Company has commenced a 40,000m Discovery drilling campaign to test nine targets for new high-grade sulphide shoots "under the headframe" at Wiluna.

High-grade >5g/t shoot discoveries are targeted to substantially enhance the early years of the current mining plan with the intention of increasing the underground ore grade which will support plans to grow gold production with higher grade mining areas. The Company is targeting large-scale, high-grade shoot targets like those historically mined at Wiluna, such as the Bulletin shoot that has an endowment of past production combined with the current mineral resource of approximately 1.5Moz @ 7g/t. Initial targets include shallow strike extensions in the upper 600m on both the East and West structures, and below the major historical production areas. Targets are defined where the Wiluna orebody remains open along strike, down dip and on parallel structures.

Sulphide shoots are interpreted to have formed in a predictable structurally repeated pattern controlled by the steeply south-plunging shoot corridors in conjunction with north- plunging trends and rock unit boundaries. In addition, first-pass seismic transverse lines acquired during 2021 showed that gold structures extend well below and beyond the current Mineral Resource limits, supporting Discovery drill hole targeting.
