ABSTRACT:De Grey Mining Ltd (ASX: DEG, “De Grey”, “Company”) is pleased to provide results and outcomes of the Wingina drilling program. The Wingina program (Figure 1) has been successful in confirming shallow and potentially open pittable high grade lodes and defining further extensions to the Wingina mineralisation at depth. Importantly, the drilling has also provided a substantial advance in the geological understanding of the deposit and the impetus to review the longer term potential along the regional Wingina Shear Zone (“WSZ”) and greater Tabba Tabba Thrust. The overall Wingina drilling program has now been finalised with results and conclusions provided in this report. The programme included two specific objectives: 1. Shallow oxide drilling of the known and thickest portions of the high grade lodes for confirmation of grade and structural information; and 2. Wingina Deeps drilling to determine potential for high grade mineralisation at depth, as well as to obtain fresh core to provide geological information and metallurgical assessment of mineralisation in fresh bedrock. The shallow oxide zone drilling has been successful in confirming the high grade nature of the definition of strong high grade gold lodes within the Wingina resource (Figure 1 - stacked cross sections). These high grade lodes are continuous over the entire 600m strike length and to the depth of detailed drilling to date (~200m vertical depth) and will be very important in future mining optimization scenarios. Structural information gathered has been limited due to the oxide material and highly variable recoveries were achieved while drilling the silicified to very soft altered rocks of the target zone. The second planned hole was deferred until a later date when additional equipment can be used to improve recoveries.
