Special Report: Drilling at De Grey’s Hemi discovery has returned consistent gold endowment at the Falcon intrusion that remains open in multiple directions.

Thick intervals of gold mineralisation were intersected with notable results such as 92m grading 1.3 grams per tonne gold from a depth of 124m that is 50m up dip of a previous interval of 92m at 1.3g/t gold from 167m.

Additionally, some of the holes ended in mineralisation with De Grey Mining (ASX:DEG) planning to drill a diamond tail for at least one hole.

“The latest results at Falcon demonstrate the consistently high gold endowment of this zone along a strike of 1,000m and to a depth of at least 350m,” managing director Glenn Jardine said.

“Mineralisation remains open down dip, along this strike and up dip on some sections. Drilling will continue to expand the mineralisation at Falcon to define a resource in mid-2021.”

De Grey has restarted its aggressive drilling campaign at Hemi with eight rigs – two aircore, three reverse circulation and three diamond rigs – currently operating on site.

“As well as delineating the existing zones at Hemi, aircore and RC drilling is progressively expanding to known and new intrusive targets in the Greater Hemi area,” Jardine added.

“Aircore and RC drilling to identify new zones outside Hemi is currently focused to the north and west of Crow.”

Falcon adding more gold

The Falcon intrusion is about 600m west of Brolga and immediately south of Aquila.

Bedrock mineralisation at Falcon is covered by about 30m to 40m of transported material, similar to the cover at the Aquila, Brolga and Crow deposits.

Step-out and infill drilling has already demonstrated consistently thick zones of gold mineralisation up to 80m wide, 350m down dip and over 1km in strike.

And there is more to find as mineralisation remains open at depth along the entire strike.
