Special Report: De Grey Mining (ASX:DEG) has demonstrated the potential for higher-grade lodes at its Aquila and Crow deposits within its Hemi gold discovery in WA’s Pilbara region.

Further drilling has unlocked the potential of its Aquila and Crow ore bodies that lie adjacent to the explorer’s Brolga intrusion at its company-defining Hemi gold discovery.

In the Aquila deposit, latest drilling results show its mineralisation remains open and extends beyond 800m east-west, and to a confirmed depth of ~400m.

“Drilling at the western end of Aquila continues and has extended mineralisation at depth and to the west toward Falcon [another De Grey gold deposit],” managing director, Glenn Jardine, said.

An impressive hit from the Aquila drilling was 24.6m at 2.7 grams per tonne (g/t) gold from 244.3m, including 5m at 5 g/t from 252m.

Crow deposit mineralisation has a 500m strike length and remains open

At the eastern edge of the Crow prospect, high-grade gold was intersected, and the mineralisation remains open to the east and over a strike length of 500m.

One intersection at Crow was 17m at 12.9 grams per tonne (g/t) gold from 91m that included 7m at 29.4 g/t from 94m.

“The new results at Crow continue to demonstrate the potential for higher grade lodes within the large, broad mineralised zones,” Jardine said.

Drilling at the southwestern portion of Crow has also revealed depth and strike extensions to the ore body, and mineralisation is open along strike and up and down dip.

“A broad mineralisation zone is present at least 400 metres below surface that includes narrower high-grade intervals,” said Jardine.

The company recently revealed extensions to the Crow deposit to the northwest, and potential extensions may lie to its northeast and southwest.

Additional infill drilling planned and a JORC resource estimate is expected in mid-2021

“Drilling will continue at Crow to infill and expand the mineralised deposit,” Jardine said.

De Grey Mining has seven drill rigs operating at its Hemi discovery carrying out infill resource drilling and testing new and extensional targets.

“Total metres drilled at Hemi now exceed 200,000 metres since the discovery in December 2019,” said Jardine.

A maiden JORC resource estimate for the Hemi gold discovery, located 60km south of Port Hedland in WA, is expected in mid-2021.
