Thick, Near Surface, High Grade Hemi Hits Continue
De Grey Mining Limited (ASX: DEG) at the Hemi Gold Discovery has had further drilling success at its new Falcon intrusion find at the exciting Hemi gold discovery near Port Hedland in Western Australia.
The new Falcon intrusion is located approximately 600m west of the Brolga and immediately south of Aquila intrusions at Hemi.
Technical Director, Andy Beckwith, said this recent discovery is now defined by aircore drilling over approximately 3.0km in strike, remaining open to the south. The bedrock mineralisation is covered by approximately 30m to 40m of transported material, similar to the Aquila, Brolga and Crow deposits.
The style and intensity of alteration and brecciation as Falcon is similar to the nearby Aquila deposit.
Step out RC and diamond drilling results show continued robust and broad zones of gold mineralisation up to 80m wide, +250m down dip with over 800m strike, with mineralization remaining open.
RC drilling is currently underway testing along strike to the south on a nominal 80m x 80m step out basis. Diamond drilling of deeper extension will progress as results warrant. Over 2km of strike remains to be RC and diamond drill tested.
Diamond drilling of hole HERC236D on section 7691800N, has also intersected encouraging highly brecciated and sulphide altered intrusion from the bottom of the RC pre-collar at 226.6m to 281m with the hole finishing at 330m.
This hole is targeting mineralisation at depth below the previously reported intersections of 16m @ 3.7g/t Au from 43m in HERC141 which ends in mineralisation and 31m @ 1.3g/t Aufrom 88m in HERC234.
“The new results combine to define strong and robust gold mineralisation up to 80m wide, over 800m of strike and greater than 250m depth with mineralisation remaining open,” Mr Beckwith said.
“Aircore drilling continues to extend the intrusion to the south with step out RC drilling continuing to systematically test along this 3km long target.
“The known mineralisation at Falcon has grown rapidly to 800m strike length and now has similar dimensions to Aquila.”
