Explorer of the moment De Grey Mining Limited (ASX: DEG) has continued its impressive run of gold discovery success in Western Australia’s Pilbara Region by defining a large gold zone at the Crow prospect within its exciting Hemi Discovery area.
The Crow Zone represents a large zone of gold mineralisation defined by recent wide-spaced air core drilling extending over an area +1000m x +400m, to the north of the Aquila Zone. A single fence of six RC holes were recently drilled to provide an initial test of the bedrock to a nominal depth of 150m.
DeGrey Technical Director, Andy Beckwith, said the initial results at Crow has shown the potential for another large tonnage gold deposit similar to the large Brolga zone discovered earlier this year.
These are the first six RC holes we have drilled into Crow. The results show an extensive +400m wide zone of semi continuous gold mineralisation throughout the entire intrusion from Aquila through to Crow,” Mr Beckwith said.
“The alteration and gold mineralisation at Crow is similar to that seen at Brolga. Looking at the cross section, if the gold mineralisation at Aquila and Crow join at depth then we have a target larger than Brolga with a potential lateral width of +700m.
“Drilling is at an early stage and we look forward to further testing this potential.”
The RC drilling intersected continuous intrusion from Aquila to Crow, indicating the Aquila Zone is on the southern margin of the larger Crow intrusion.
The scale of the Crow intrusion and associated gold mineralisation is significant with the drilling defining semi- continuous gold mineralisation over a lateral width of +400m and the potential to extend further down dip and possibly may join with the Aquila Zone. These dimensions coupled with strike potential of +1km provide substantial upside.
Assays results of the RC drilling have been received and confirm extensive gold mineralisation throughout the Crow intrusion associated with the alteration zones. The mineralisation is similar to the mineralisation at both Aquila and Brolga. High grade intervals also occur within the broad lower grade mineralisation.
The overall broad gold zone is shallow south dipping and may join the Aquila zone at depth. Mineralisation remains open down dip and along strike.
As a consequence of the positive results in this initial RC drilling programme, DeGrey said the next program of step out RC drilling on a nominal 160m x 80m spacing, for approximately 5000m, has now been planned to test Crow along strike.
This programme is expected to commence during May, in conjunction with ongoing drilling at Aquila and Brolga.
