De Grey Mining Drills Brolga Plunge Potential

THE DRILL SERGEANT: De Grey Mining (ASX: DEG) reported on drilling carried out on the Brolga prospect, part of the company’s Hemi gold discovery in Western Australia.

Brolga is the largest gold zone discovered at Hemi to date where De Grey’s recent drilling has targeted down dip and strike extensions to the main Brolga zone, in addition to resource infill drilling.

Drill hole HERC392D has extended mineralisation at Brolga while confirming a developing plunge that remains open to the south-west.

Results include:
256 metres at 0.9 grams per tonne gold from 287m, including:
− 14.9m at 2.2g/t gold from 294m;
− 50m at 1.1g/t gold from 412m;
− 18m at 1.5g/t gold from 468m;
− 9m at 3.1g/t gold from 497m; and
− 15m at 1.1 g/t gold from 528m.

The hole ended in mineralisation.

“Recent extensional RC and diamond drilling has been successful in identifying wide zones of mineralisation along in the west of the large Brolga mineralised system and remains open to the south, west and at depth,” De Grey Mining managing director Glenn Jardine said in the company’s ASX announcement.

“Higher grade intervals within the larger mineralised system have also been intersected.

“RC drilling is in progress to extend mineralisation further between Brolga and Brolga South and between Brolga and Falcon.

“Results of infill drilling continue to show broad zones of consistent gold mineralisation and strong correlations between adjacent drill holes.

“The infill program is designed to provide sufficient drill density to enable a significant portion of the maiden resource estimate to meet JORC 2012 Indicated classification.”

Extensional drilling is being conducted to the west and south of the main Brolga zone.

Drilling has demonstrated that the Brolga mineralised system is open at depth and along strike to the west and south.
