Wiluna Mining Corporation Limited announce the completion of Resource development drilling for its Sulphide Development Feasibility Study. The focus of recent drilling has been threefold: to increase the level of confidence in the Mineral Resource at the Wiluna Mining Centre, increase the confidence in high priority mining areas in the 1 to 5 year mine planning window, and to confirm the Company's Reserves. Infill drilling remains ongoing with 3 rigs currently drilling as part of the Company's ongoing Resource development program with a focus now towards underground mine development and grade control. Wiluna Mining's drilling strategy in the past 18 months has successfully defined thick high-grade intervals at shallow levels, close to previously mined zones with available access for rapid low-cost development. These results demonstrate that the Wiluna orebody is a very large scale and high-grade gold system. 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 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 to provide the foundation for a sustained long term production operation. Currently the Measured and Indicated Resource is 2.14Moz @ 5.26g/t (above 2.5g/t cut-off). The additional Inferred Resource at Wiluna is 2.10Moz @ 4.57g/t (above 2.5g/t cut-off). The program was aimed at infilling the Inferred Resource areas, to upgrade geological confidence to Indicated or Measured categories to facilitate the conversion of these areas to Reserves. However, the program also shows potential for Resource growth where holes have intersected the mineralised shear zone below the current Inferred and Indicated Resource limits.
