- De Grey Mining (DEG) has provided updated drill results for the Brolga and Aquila Zones, both of which are located within the Hemi Discovery in WA
- Gold mineralisation has been extended at Brolga and sulphide mineralisation was also intersected
- Results from Brolga peaked as high as 2.4 grammes per tonne gold
- Drilling at Aquila is also continuing to extend gold mineralisation and results reached as high as 14.3 grammes per tonne gold
- Reverse circulation and diamond drilling is now ongoing and aiming to extend the gold mineralisation
- De Grey is down a slight 4.29 per cent in mid-morning trade and shares are selling for 33.5 cents each
De Grey Mining (DEG) has provided updated drill results for the Brolga and Aquila Zones, both of which are located within the Hemi Discovery.
Hemi
Hemi is located in the Mallina Gold Province of Western Australia which lies 60 kilometres south of Port Hedland.
The three gold anomalies at Hemi, Aquila, Brolga and Crow, were defined by aircore drilling.
Reverse circulation (RC) and diamond drilling has been ongoing at Aquila and Brolga since February 2020 and results have confirmed significant gold mineralisation at both zones.
The Crow Zone is relatively new and deeper RC drilling began in April 2020 and results for the majority of the holes are expected at the end of this month.
Drilling was undertaken at Crow to determine if Crow and Aquila share mineralisation due to the close proximity.
Brolga
At Brolga, broad gold mineralisation is continuing to be defined at depth and length and the mineralisation remains open along strike to the east and west, and also down dip.
Recent RC drilling has also intersected sulphide mineralisation.
It has also shown that gold mineralisation extends into the hanging wall and footwall sediments. Further drilling will be undertaken to test these.
While results for some holes are still being assessed, significant ones include 15 metres at 2.4g/t gold from 40 metres, 38 metres at 1.6g/t gold from 168 metres, and 29 metres at 1.1g/t gold from 148 metres.
Further RC drilling is now underway to test the east, west, and depth extensions of the gold mineralisation.
Aquila
The Aquila Zone is located 200 metres north of Brolga and 200 metres south of the new Crow Zone.
Drilling at Aquila is continuing to test the gold mineralisation along a length of 800 metres and a depth of 300 metres. Gold mineralisation remains open both along strike and down dip.
While RC drilling at Brolga was relatively easy, RC drilling at Aquila has proven to be more difficult due to the intense alteration and deeper weathering profile.
Due to this, the majority of the RC holes have been stopped short from the planned depths and diamond drilling is required to complete the rest.
Significant results from Aquila include 16.2 metres at 3.3g/t gold from 249.3 metres including 1.8 metres at 11.8g/t gold and 0.6 metres at 14.3g/t gold, and two metres at 3.2g/t gold from 76 metres.
"The overall scale of Hemi continues to grow, with three large zones in Aquila, Brolga and the new Crow defined to date," Technical Director Andy Beckwith commented.
"We have a further four other significant intrusions in the immediate area, Scooby, Antwerp, Shaggy and Alectroenas over a strike length of 15 kilometres still to test," he said.
RC and diamond drilling is now ongoing and three rigs are operating between the Brolga, Aquila and Crow Zones.
The aim of this is to test for further extensions to the gold mineralisation and results will be made available once the program is completed.
De Grey is down a slight 4.29 per cent in mid-morning trade and shares are selling for 33.5 cents each at 11:06 am AEST.
