Wiluna Mining Corporation Limited announce the confirmation of high-grade sulphide mineralisation in the first of eight holes testing down-plunge extensions of the East and West Lodes, which historically were the main producing lodes at Wiluna with a combined endowment of 3.5Moz @ 5.4g/t. The Company's 40,000m discovery drilling campaign will test nine large-scale targets for new high-grade sulphide shoots `under the headframe' at Wiluna. Drilling is currently underway at East and West Lode Lower, Bulletin North and Squib. High-grade >5g/t shoot discoveries are targeted to enhance the early years of the current mining plan with the intention of increasing the underground ore grade and to grow gold production.

The East and West Lodes were historically mined to 600m depth during the 1930's and 1940's and produced 1.4Moz @ 7.6g/t, until production ceased at the end of World War II. When combined with the current Mineral Resource, the East & West Lodes have a large pre-production endowment of approximately 3.5Moz @ 5.4g/t. A small number of wide-spaced holes were drilled below the lodes in the late 1990's, which confirmed the continuity of the gold structures, although high-grade shoot trends were not adequately tested in the previous program. The East & West Lode discovery program tests for a repeat of the East and West Lode endowment, in a large target area of approximately 1,000m strike extent and between 800m to 1,500m below surface, in an area that has been sparsely tested despite the large-scale and high-grade past production.

Holes are designed to intersect modelled high-grade shoot locations on both the East and West Lode structures, which are sub-parallel structures less than 200m apart. Outstanding assays received from the first hole in the program confirm the continuity of high-grade mineralisation approximately 200m down-plunge of the limit of historical mining and the current Mineral Resource envelope. Intercepts include: WUDD0077: 9.40m @ 4.87g/t including 6.60m @ 6.22g/t, and 1.80m @ 9.74 g/t, WUDD0077 also intersected the West Lode at the modelled position with trace amounts of sulphides, shearing and alteration indicative of low-tenor gold mineralisation with assays pending.

Importantly, the West Lode intersection is approximately 700m below the limit of historical drilling and the current Mineral Resource, which confirms the large-scale continuity of the West Lode structure. The Company's geological team has developed a model that predicts the location of high-grade sulphide shoots in a repeated pattern controlled by the junction of steeply east-dipping mineralised structures with rock unit boundaries. Additional subtle north-plunging and south-plunging high-grade shoots are aligned with pre- mineralisation structural trends.

The East and West Lode structures are variably mineralised between the shoots and are prospective for further discoveries to be made along strike to the north and south, and at depth. The significance of the East and West Lode intersections in WUDD0077 is that they confirm new extensions to mineralisation well below the deepest historical drilling and the current Mineral Resource limits. The intersections are located at relatively shallow depths of 800m to 1000m below surface, and close to the Golden Age and Calais mine areas.

The existing development at Golden Age and Calais may provide for rapid and low-cost access for further drilling of these new sulphide zones, subject to further results from the current drilling program.
