Special Report: The ‘Falcon’ intrusion at De Grey’s (ASX:DEG) mammoth Hemi gold discovery is growing fast. At 80m wide, +800m long, +250m deep and growing, it now has similar dimensions to ‘Aquila’.
The recently discovered Falcon intrusion at Hemi is immediately south of the Aquila deposit.
Like the Aquila, Brolga and Crow deposits, Falcon is hidden by a 30m to 40m blanket of transported material.
New 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 mineralisation remaining open.
Significant new drilling results include 42m at 5.2g/t including 31m at 6.6g/t gold, 50m from surface.
That’s thick, shallow, and high grade.
A further 2km of strike identified in early stage aircore drilling remains to be tested, De Grey says.
This aircore drilling extends the Falcon intrusion 500m to the south, providing an overall 3km of strike which remains ‘open’.
“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,” De Grey technical director Andy Beckwith says.
“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.”
Upcoming drilling at Hemi
Priority drilling programs going forward are focused on initially testing the 3km strike potential at Falcon with RC drilling and deeper diamond drilling, says De Grey.
This will define the mineralised footprint prior to infill resource drilling.
De Grey will also focus on extensional and infill drilling at Crow and Aquila, as well as aircore drilling at South Brolga and other regional intrusion targets.
