De Grey Mining Limited (ASX: DEG) has added further momentum to its exciting Hemi discovery in Western Australia’s Pilbara Region, with further drilling success at the Brolga Zone.
The company has received further positive gold assays for the three diamond holes completed on section 30,640E, one diamond hole on section 30720E and additional results for five RC drill holes on sections 30,400E, 30,480E and 30960E.
Two additional diamond tails (HERC035D and HERC037D) have also been completed at Brolga and HERC036 have assay results pending.
Exploration Manager, Phil Tornatora, said broad gold mineralisation continues to be defined down dip and along strike at Brolga. Gold mineralisation remains open along strike to west and east and down dip. Overall gold mineralisation is now defined from 30,400E to 30,960E (560m) with the strongest mineralisation currently between 30,400E and 30,720E.
The two recently completed diamond tails to the west have also intersected extensive zones of intrusion to the end of holes at 448m and 529m downhole depths respectively. Encouraging sulphide mineralisation has also been intersected to approximately 320m below surface.
Mr Tornatora said encouraging gold mineralisation has now been intersected both in the hanging wall and footwall sediments.
“This is an important new aspect, as it provides additional large and essentially untested potential in the Hemi prospect area,” he added
Further RC and diamond drilling is planned to recommence at Brolga after completion of priority holes at Aquila and initial testing of the area of aircore drilling area north of Aquila.
“Mineralisation remains open in most directions at Brolga and now we are seeing gold in the adjacent sediments as well,” Mr Tornatora said.
“Drilling is providing more detail on the deposits, possibly showing a large scale SW plunge to mineralisation at Brolga.
“Many holes have encountered broad gold zones, that have finished in gold mineralisation and remain open.
“Drilling will continue to focus on extensions to the SW, NE and at depth.
“We expect to provide the next update on Aquila and the aircore drilling to the north after Easter.”
