THE DRILL SERGEANT: De Grey Mining has defined a third gold zone within the Hemi gold discovery at the company’s Pilbara gold project in Western Australia.
Recent drilling undertaken by De Grey Mining has defined the new Crow zone, a NE trending gold in bedrock anomaly one kilometre long and 300 metres wide, north of and parallel to the Aquila and Brolga zones within the Hemi discovery area.
The company had previously confirmed the Aquila and Brolga zones to host strong gold-sulphide mineralisation with deeper RC and diamond drilling.
Additional aircore drilling, mostly to the north of Aquila, returned further encouraging gold results at the new Crow Zone, highlighted by the maximum bedrock gold value in each aircore hole.
De Grey claims the scale of the Crow Zone as being similar to the Brolga and Aquila zones with aircore drilling extending the known extents of the northern intrusion.
To date, De Grey has completed six RC holes (HERC043-HERC048), testing from Aquila and across a portion of the Crow anomaly.
Results for HERC043 have been received, demonstrating encouraging bedrock gold mineralisation in a broad interval that finished in mineralisation.
+72 metres at 0.3 grams per tonne gold from 42m, including 4m at 0.7g/t gold from 42m, 4m at 1.2g/t gold from 70m, 4m at 0.5g/t gold from 80m, and 6m at 0.8g/t gold from 106m.
“Crow is an exciting new large and untested gold anomaly, which has the dimensions and a similar order of magnitude of aircore gold results as initially seen at Brolga,” De Grey Mining exploration manager Phil Tornatora said in the company’s announcement to the Australian Securities Exchange.
“Like Brolga, the aircore drilling has only tested the shallow weathered portion of the bedrock.
“The first RC drill section comprising six holes has been completed, encountering variable sulphide mineralisation in each hole.
“HERC043 has returned encouraging gold mineralisation.
“We expect results of the next five holes to be available towards the end of April.”
