Wiluna Mining Corporation Limited announced further high- grade sulphide intersections from an additional 63 holes and 16,705m of resource development drilling, and provides an update on the Company's Fiscal Year 2022 Discovery Strategy. Happy Jack and East Lode are important early sulphide mining zones where redevelopment of the underground operation is already well advanced ahead of production. These further high-grade results are expected to enhance Mineral Resource and Ore Reserve updates that are scheduled for completion later in 2021, as these results are infilling Inferred Resource areas to improve geological confidence and hitting high grades at good mining widths beyond the current Resource extents. The Company also continues to define extensions to the Golden Age orebody, which is a source of high-grade free-milling feed that currently supplements large ore stockpiles from mining the Williamson pit, enhancing head grade and cashflows ahead of sulphides production. Currently five rigs are drilling to further infill and grow the large high-grade gold system at Wiluna, with the intention to update the Mineral Resource Estimate and Ore Reserve estimates in the final quarter of calendar 2021, as part of the Company's in-progress Stage 2 Feasibility Study. The Company's goal is to add 500,000oz of high-grade, shallow Ore Reserves through further infill drilling of the existing resource base and to build a 2.5Moz Measured and Indicated Resource to enhance mine planning and long-term option studies (currently the M&I Resource is 2.14Moz @ 5.26g/t, above 2.5g/t cut-off). Including historical production of over 4Moz, Wiluna's gold endowment defined to date is over 10Moz which ranks Wiluna alongside an exclusive peer group of large-scale, long-life mining centres in the Western Australian gold fields. Most historical production and existing Resources occur in the upper 600m at Wiluna, with limited drilling during the past 15 years at depth on Wiluna Mining's exploration targets, which Wiluna Mining is systematically drilling out to complete the Resource development program over the next five years. The ongoing drilling program is focused on highest-value zones scheduled for mining to further enhance the mine plan, with results reported here from Happy Jack and East Lode. Geological interpretation and resource estimation are in progress for the recently completed programs at Starlight, Essex, Bulletin, Calvert and West Lode zones where results have been reported. Drilling has continued to improve the size and tenor of the high-grade free-milling Golden Age quartz reef orebody, while extensional drilling has further extended the zone to the east where mineralisation remains open (Figure 2). The area below the 650m level at Golden Age East remains untested and when coupled with the high-grade mineralisation intersected around the 850m level, a considerable drilling target area remains open that may host more high-grade mineralisation. Happy Jack and East Lode continue to deliver high-grade intercepts over good mining widths at shallow depths. The program is primarily aimed at infilling the Inferred Resource areas within mining inventory, with a view to upgrading geological confidence to Indicated category and converting these areas to Reserves. The program also aims to grow the high-grade resource beyond the current extents of the Inferred and Indicated Resource. In addition to the Company's focus on defining shallow, high-grade Ore Reserves for the sulphide development, the geological program aims to reveal the full scale of the very large gold system at Wiluna to over 1,800m below surface with multiple targets "under the headframe" to be drilled. The ongoing program is targeting high-grade resource extensions greater than 5g/t, located close to the surface and close to existing underground infrastructure for lower costs per ounce developed. Priority targets for drilling in 2021-2022 include Bulletin northern extensions, and down-dip and along strike to the south of the East Lode and West lode zones. The Company aims to discover analogues to the historically mined Bulletin main shoot which produced 900,000oz @ 8g/t. The Company's geologists have identified multiple targets where ore shoots may have formed, in a predictable structurally repeated pattern controlled by the steeply south-plunging shoot corridors in conjunction with conjugate north-plunging trends. The Company is targeting high-grade zones to bring into the front of the mine plan, because every increase in head grade of 1g/t equates to approximately 25kozpa additional ounces during Stage 1 production and 50kozpa during Stage 2 of the Sulphide Development plan.
