Special Report: De Grey is embarking on a flurry of activity for its Hemi gold discovery in Western Australia’s Pilbara region that includes extension drilling and preliminary metallurgical testwork.

Over the next three months, exploration at Hemi will focus on new intrusion-style gold mineralisation that the company has discovered at the prospect along with the known shear zone-style deposits.

De Grey Mining (ASX:DEG) has also started preliminary metallurgical testwork on oxide, transition and primary mineralisation samples from the Brolga zone to provide indications as to the potential process flowsheet for the deposit and recoveries that could be expected.

Work at Hemi will include extension drilling at the Aquila, Brolga and Crow zones with one reverse circulation and two diamond drill rigs.

Holes will be drilled to a depth of about 300m to 400m at 80m by 80m spacings with the goal of extending the lateral limits of mineralisation.

Aircore drilling has also recommenced with continued step out extensions to the northeast and southwest of Hemi to test for potential mineralised extensions.

Additionally, De Grey will carry out exploration drilling along the immediate strike of more than 10km from the Scooby to Antwerp prospects, where shallow first-pass drilling had intersected up to 4m at 21.7 grams per tonne gold.

The company will also acquire a detailed regional aeromagnetic survey over an area of about 30km by 10km to provide greater definition to the existing intrusions and delineation of new intrusions along this corridor.

Hemi was discovered in mid-December 2019 under a shallow ‘blanket’ of transported cover, with subsequent work highlighting the potential for the broader and still underexplored Mallina project to host a resource much bigger than its existing 2.2 million ounces of gold.

The company’s ongoing success has also been instrumental in its completing a heavily oversubscribed $31.2m share placement to fund exploration and early development.
