De Grey’s Falcon is soaring as drilling hits more depth extensions

De Grey continues to expand the scale of the Falcon intrusion with drilling intersecting major depth extensions of its gold mineralisation.

Notable results include 55m at 1g/t gold from 263m and 16.5m at 1.1g/t gold from 324.5m from the deepest hole drilled to date at Falcon, which also shows the mineralised intrusion within its Hemi discovery extends to 450m below surface.

De Grey Mining (ASX:DEG) exploration manager Phil Tornatora says the Falcon intrusion is increasing to about 100m thick at depth with multiple new footwall lodes beginning to develop as the intrusion thickens at depth.

He added that infill drilling such as 19m at 1.3g/t gold from 55m within a broader zone of 42m at 1g/t gold from 45m and 20m at 1.8g/t gold from 64m is providing confidence in the continuity and consistency of gold mineralisation.

“Falcon is open at depth and deeper step-out diamond drilling is being prioritised to test this potential,” Tornatora noted.

“These recent results, and further depth extensions, have the potential to significantly increase the already substantive gold endowment at Falcon.”

Falcon gold intrusion

Falcon is about 600m west of the Brolga deposit and immediately south of the Aquila deposit, with which it shares a similar style and intensity of alteration and brecciation.

The bedrock mineralisation is covered by about 40m of transported material, similar to 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.

With the latest work, Falcon has now been tested with reverse circulation and diamond drilling to 80m by 40m spacing and a maximum vertical depth of about 280m.

Mineralisation dips steeply to the east and remains open at depth along the entire strike length.

The next phase of drilling at Falcon includes 160m spaced step out diamond holes to test the main mineralised zone at a vertical depth of around 450m and will be extended to test the new footwall lodes.
