THE DRILL SERGEANT: De Grey Mining (ASX: DEG) produced further results from the Brolga and Aquila Zones within the Hemi gold discovery, located within the company’s Pilbara gold project in Western Australia.
De Grey Mining has identified extensive sulphide mineralisation from RC and diamond drilling over 240 metres of strike length and has demonstrated additional strike potential from encouraging aircore gold results and observations along strike over approximately 600m.
The overall scale of the Brolga Zone remains open in all directions that is currently defined only by RC and diamond drilling.
The dimensions of the Brolga Zone currently stand at 240m strike by up to 200m wide by 220m below surface and remains open.
De Grey said RC drilling undertaken on section 30,640E had confirmed substantial thicknesses of gold mineralisation associated with the extensive sulphide rich mineralisation.
RC gold results on Section 30,640E include:
43 metres at 1.9 grams per tonne gold from 99m, including 6m at 4.3g/t gold and 4m at 5g/t gold;
36m at 3.2g/t gold from 156m, including 14m at 5.6g/t gold; and
43m at 1.9g/t gold from 34m, including 6m at 6.9g/t gold.
Drilling at the Aquila Zone has demonstrated gold potential over 800m strike, up to 50m thick and 180m depth and remains open.
RC drilling results confirm healthy gold mineralisation, including:
51m at 2.1g/t gold from 108m, including 8m at 4.9g/t gold;
62m at 1.4g/t gold from 59m; and
20m at 2g/t gold from 142m, including 3m at 6.8g/t gold.
“Brolga and Aquila are developing into two very large gold systems with widths of gold mineralisation never seen before in the project area nor the Pilbara region,” De Grey Mining technical director Andy Beckwith said in the company’s announcement to the Australian Securities Exchange.
“The ongoing RC and diamond drilling program aims to scope the overall scale of the mineralisation on 80m spaced sections.
“The large anomalous gold area to the north of Aquila is now our focus for aircore drilling.
“Anomalous gold occurs in every hole above the interpreted intrusion in earlier wide spaced aircore drilling and provides scope for further new parallel discoveries.”
