Aquila Zone Expands Hemi Footprint
De Grey Mining Limited (ASX: DEG) continues to build on its exciting Hemi gold discovery in Western Australia’s Pilbara Region with more drilling at the Aquila Zone.
Exploration Manager, Phil Tornatora, said the gold endowment at Hemi continues to grow with drilling still to define the limits of mineralisation. Aquila is a 1.2km long linear mineralised zone located between the Brolga and Crow intrusions at Hemi and Mr Tornatora said its remains open in all directions.
Two high grade (+5g/t) plunging shoots appear to be developing in drilling. Recent aircore drilling has provided a potential 400m strike extension. These high =-grade shoots and lateral extension have the potential to significantly increase the open pit mining potential at Aquila.
Mr Tornatora said recent RC and diamond drilling continue to extend broad scale gold mineralisation with the 4 rigs operating at all mineralized zones at Hemi. RC drilling has been adversely affected for a week in mid-June due to mechanical availability.
The RC rig has also been completing pre-collars for deeper diamond drilling at Aquila. Aircore drilling is continuing to the southwest of Hemi targeting mineralised extensions. A second aircore rig will extend coverage to the east of Hemi toward Scooby commencing this week.
“The Aquila style gold mineralisation identified in highly altered intrusion 400m to the west is an exciting and significant development as it opens up the overall strike potential of the deposit,” Mr Tornatora said.
“The broad high-grade mineralisation announced today is particularly encouraging demonstrating the potential to rapidly add to Aquila’s gold endowment.
We are now targeting diamond drilling to extend Aquila to at least 300m below surface along the entire strike of the deposit.
“The potential to extend Aquila a further 400m to the west under an interpreted shallow veneer of sediments is an exciting development and will also be targeted.
“Similar potential remains to be tested to the east under the sediment contact.
“Diamond core assays of the depth extensions below the recent high-grade intercepts are in the lab with results expected shortly.
“Stepout extension diamond drilling is on-going with a further 8 pre-collars already completed. A second RC rig arriving next week will help accelerate drilling on all mineralised zones at Hemi.”
