De Grey Mining hits high-grade, visible gold at latest Hemi target

De Grey Mining ASX DEG high-grade visible gold Hemi target Crow
Latest drilling at De Grey’s Hemi discovery unearthed 64m at 13.4g/t gold at the Crow prospect.

In another milestone announcement, De Grey Mining (ASX: DEG) has extended the mineralised footprint of its Hemi gold discovery that could add significantly to its already substantial gold endowment in the Pilbara.

The company said reverse circulation (RC) drilling at the Crow prospect has intercepted “thick, high-grade gold”, including visible gold.

Hole HERC238 returned 64m at 13.4 grams per tonne gold, including a 19m section assaying at 42 g/t (and which, in turn, contains 8m at 84.7g/t). Mineralisation began 141m down hole.

Other holes returned 12m at 2.4g/t. 24m at 1.1g/t and 31m at 2.2g/t,

Managing director Glenn Jardine stressed the importance of this hole to De Grey’s future, saying that it had transformed the company’s perceptions of the large Crow intrusion.

“The significance of the new RC results at Crow goes beyond the results of HERC238.

“They demonstrate the potential for Crow to significantly add to the overall gold endowment at Hemi and to meaningfully contribute to a potential large scale, near surface open pit production scenario,” Mr Jardine said.

De Grey says Hemi heading for tier-one status

He added that De Grey’s drilling program is working successfully toward the strategic goal of making Hemi a tier-one scale gold deposit.

Hemi lies within De Grey’s Mallina project that covers 1,200sq km of the Mallina Basin and is 50km south of Port Hedland.

In late 2019 a major gold discovery was made at Hemi in the central area of the project area.

As described by the company, gold mineralisation at Hemi is hosted in a series of intrusives associated with stringer and disseminated sulphide rich zones.

“This style of mineralisation is new to the Pilbara region and shows a scale of mineralisation not previously seen in the Mallina Basin.”

The Crow results follow recent announcements by De Grey of the new sub-vertical lodes at that prospect, together with mineralised extensions of Crow to the north-west.

De Grey reported that the overall scale at Hemi continues to increase, now measuring 2.5km north-south and 2km east-west, with three main zones: Aquila, Brolga and Crow. Crow now measures 1km long by 400m wide.

There are six drill rigs in operation: two aircore, two RC and two diamond.

Mallina was the location of one of the early gold mines in Western Australia.

The Mallina Gold Mining Company, based in Glasgow, was floated in 1893 with a capital of £100,000. Its life was short-lived.
