Wiluna Mining Corporation Limited announced the discovery of strong 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 past production and current Mineral Resources of 3.5Moz @ 5.4g/t. Drilling success at East Lode Lower follows the recently reported ultra-high-grade results at the Bulletin North
target. The Discovery programs are part of a 40,000m campaign testing nine large-scale targets for new high-grade sulphide shoots `under the headframe' at Wiluna. Drilling is in progress at East and West Lode Lower, Bulletin North and Squib. 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 and to grow gold production. The current targets are a subset of the Company's JORC- compliant Exploration Target at the Wiluna Mining Centre of 35Mt to 40Mt @ 4.5g/t to 7g/t for 5Moz to 7Moz. The potential quantity and grade of the Exploration Target is
conceptual in nature and is therefore an approximation. There has been insufficient exploration drilling to estimate a Mineral Resource in the target areas, and it is uncertain if further exploration will result in the estimation of a Mineral Resource. East & West Lode Lower Targets: The historical workings at East Lode produced 720,000oz @ 6.7g/t between 1931 and 1946, and the West Lode produced 690,000oz @ 8.6g/t between 1932 and 1946. When combined with the current Mineral Resource, the East & West Lodes have a large pre-production endowment of approximately 3.5Moz @ 5.4g/t. The East & West Lode Discovery program tests for a repeat of the East and West Lode endowment, in a broad 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 both the East and West Lodes, which are sub-parallel and situated less than 200m apart. WUDD0077, the first of 8 holes at East & West Lode Lower, has intersected strong sulphide mineralisation within the East Lode structure approximately 200m below the limit of historical mining and the current resource envelope. WUDD0077 also intersected the West Lode at the modelled position with trace amounts of sulphides, shearing and alteration indicative of low-tenor gold mineralisation. Intriguingly, the West Lode intercept 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 far below the limit of past drilling. At Wiluna, gold mineralisation correlates with sulphide percentages, and the presence of strong sulphides (5% pyrite + 5% arsenopyrite) along with strong shearing and rock alteration are considered indicative of gold mineralisation. Assays are pending with an estimated turn-around time of 2 weeks. Sulphide shoots in the East & West Lower area are interpreted to have formed in a predictable and repeated pattern controlled by the junction of steeply east-dipping mineralised structures with rock unit boundaries, with additional subtle north-plunging and south-plunging high-grade shoots 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. 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.
