ABSTRACT:De Grey Mining Ltd (ASX: DEG, “De Grey”, “Company”) is pleased to provide an update on the Wingina “Deeps” diamond drilling program. The current Wingina “Deeps” drilling program aims to extend the high grade Footwall “Central” Lode into the fresh bedrock. Two drill holes (WRC211D and WRC211D2) have now been completed with a third hole currently underway. Drill holes WRC211D and WRC211D2 have both intersected a broad sequence of fresh altered BIF and internally folded Chert sequence with minor brecciation. Variable sulphide, alteration and vein development is noted throughout a large portion of the sequence. In WRC211D, broad zones of anomalous (>0.1g/t) gold mineralisation are evident throughout the altered sequence with the most significant intercepts 11m @ 1.03g/t Au and 4m @ 5.57g/t Au including 1m @ 13.8g/t Au. This high grade mineralisation is interpreted to represent the down plunge extension of the high grade Footwall Lode (Fig 1). Screen fire assays have also been completed on the individual higher grade samples and results indicate high repeatability between the two methods. Additional BLEG (Bulk Leach Extractable Gold) assays were also undertaken of the same individual high grade samples as preliminary check of the potential recoveries of the fresh bedrock ore. Recovery results are positive with an average extraction of 94.7%% in the BLEG samples.
