Results are pending for aircore drilling

De Grey Mining Limited (ASX:DEG) has released updated drilling results for the Brolga Zone within the Hemi Discovery, 60 kilometres of Port Hedland, Western Australia.

The latest RC drilling results at the Brolga Zone has defined strong gold zones on four adjacent 80 metre spaced sections associated with extensive sulphide mineralisation.

Best RC drilling results include:

  • 78 metres at 1.8 g/t from 40 metres,
  • 72 metres at 1.6 g/t from 105 metres,
  • 21 metres at 3.6 g/t from 45 metres,
  • 15 metres at 5.5 g/t from 75 metres,
  • 33 metres at 1.6 g/t from 41 metres,
  • 76 metres at 1.5 g/t from 42 metres, and
  • 56 metres at 1.1 g/t from 93 metres.

“Increasing the overall footprint”

The gold-sulphide mineralisation has a large footprint more than 340 metres of strike, up to 300 metres lateral width, up to 200 metres depth and remains open along strike and down dip.

De grey technical director Andy Beckwith said: “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.

“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."

Aircore drilling results

The aircore program has been recently concentrating on extending and infilling the wide-spaced drilling to the north of the Aquila zone where the previous aircore results had highlighted anomalous gold in all holes above the interpreted intrusions.

Results remain pending for this drilling.

Best results from the Aquila Zone are:

  • 30 metres at 1.2 g/t from 42 metres
  • 12 metres at 2.1 g/t from 44 metres

Drilling continues

The company, with the support of its various contractors, plans to continue the drilling program with the aim to test the scale of the Brolga and Aquila deposits and to continue defining the lateral and down-dip extensions to an initial nominal 400 vertical metres prior to commencing infill resource drilling.

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

The plan has been undertaken to maximise the protection of all personnel and reduce potential threats associated with COVID 19 and includes changed rosters to minimize travel and camp management to minimising external third-party interaction.

The plan is constantly being reviewed and may change at any time.
