De Grey Mining Extends Brolga Gold Mineralisation

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) released further results from drilling on the Brolga Zone within the company’s Hemi gold discovery, located near Port Hedland in Western Australia.

New RC gold intercepts encountered at Brolga include:

HERC014
78 metres at 1.8 grams per tonne gold from 40m;

HERC015
72m at 1.6g/t gold from 105m;

HERC016
21m at 3.6g/t gold from 45m
15m at 5.5g/t gold from 75m;

HERC017
33m at 1.6g/t gold from 41m;

HERC023
76m at 1.5g/t gold from 42m; and

HERC024
56m at 1.1g/t gold from 93m.

De Grey Mining has now defined strong and extensive gold mineralisation across four sections, demonstrating a robust and large growing volume of mineralised intrusive at Brolga.

The gold-sulphide mineralisation is well defined by the RC drilling, which the company has interpreted to be dipping moderately to the south (local grid) with a large footprint over more than 340 metres of strike, up to more than 300m lateral width, up to 200m depth that remains open along strike and down dip.

The company considers the shallower dipping mineralisation important, believing it has the potential to increase ounces per vertical metre within a future open pit and may reduce the overall strip ratio.

“Brolga is growing substantially, we continue to increase the overall footprint of the gold-sulphide mineralisation, particularly to the west and down dip where substantial thicknesses of mineralisation remain open,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.

“We have now confirmed the strong correlation between gold and sulphides.

“The recent four RC holes to the south and west have logged some of the strongest sulphide mineralisation noted to date.

“Drilling is planned to continue with one RC and two diamond rigs testing the limits of mineralisation at Hemi.”
