Special Report: De Grey continues to increase the scale of its Hemi gold discovery with drilling extending the mineralised zones at the Brolga and Aquila zones.

Following on from recent drilling highlighting the potential of the untested Crow zone to be “of similar scale to Brolga and Aquila”, the company has now intersected more gold at the Brolga and Aquila zones.

De Grey Mining’s (ASX:DEG) drilling has extended Brolga gold mineralisation down dip while extending sulphide mineralisation a further 80m to more than 640m long.

Notable results include 15m at 2.4 grams per tonne (g/t) gold from 40m, 38 at 1.6g/t gold from 168m and 29m at 1.1g/t gold from 148m.

Drilling also continues to confirm gold mineralisation at Aquila with top results of 16.2m at 3.3g/t gold from 249.3m, 6m at 2g/t gold from 344.8m and 6m at 2.4g/t gold from 80m.

“The overall scale of Hemi continues to grow, with three large gold zones in Aquila, Brolga and the new Crow defined to date,” technical director Andy Beckwith said.

“Our immediate plans are to continue the 80m x 80m step-out resource drilling at all three areas Brolga, Aquila and Crow with 1 RC and 2 diamond rigs active.”

De Grey has a further four intrusions – Scooby, Antwerp, Shaggy and Alectroenas – over a strike length of 15km to test.

Beckwith added that the company had started a metallurgical program with an initial focus on defining the oxide, transition and fresh domains along with completing a suite of comminution, leaching, sulphide flotation and oxidation test work.

“We expect this work will provide overall recoveries for each domain and define a potential plant processing flowsheet.”

Both Aquila and Brolga are known to host strong gold-sulphide mineralisation in the deeper bedrock while further deeper drilling is planned at Crow to test the same bedrock mineralisation.

Hemi was discovered in mid-December 2019 under a shallow ‘blanket’ of transported cover.

Since then, drilling has provided compelling support for the company’s theory that the still underexplored 2.2Moz Mallina project hosts numerous large deposits.
