De Grey’s Hemi discovery could be the Pilbara’s ‘Goldzilla’

Special Report: De Grey’s belief in the scale of the Hemi gold discovery in the Pilbara has received further validation with drilling extending the scale of the Brolga zone.
The latest results from its ongoing drilling program include 78m grading 1.8 grams per tonne (g/t) gold from 40m, 72m at 1.6g/t gold from 105m, 21m at 3.6g/t gold from 45m and 15m at 5.5g/t gold from 75m.
Additionally, reverse circulation (RC) drilling has intersected further sulphide mineralisation about 80m along strike to the west.
De Grey Mining (ASX:DEG) says the gold footprint at the Brolga zone now stretches over 340m in strike length, more than 300m in lateral width and up to 200m deep.
Brolga remains open along strike and down dip meaning that there is still room for growth.
The company also noted that the shallower dipping mineralisation had the potential to increase gold ounces per vertical metre within a future open pit and could reduce the overall strip ratio.
“We have now confirmed the strong correlation between gold and sulphides,” technical director Andy Beckwith said.
“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.”
The correlation between gold and sulphides has allowed the Company to advise that the strike of the system is now at +420m.
Last week, De Grey appointed former Azure Minerals chief operating officer Glenn Jardine as its new managing director.
Jardine has more than 35 years of experience in the mining industry and has served as the managing director for Lion Ore Australia, project manager of the Emily Ann and Maggie Hays nickel mines and both project manager and general manager of the Henty gold mine in Tasmania.
He will start in his new role on May 4, 2020.
Since then, drilling has provided compelling support for the company’s theory that its rapidly growing — but grossly underexplored — 1.7-million-ounce Mallina project hosts numerous large deposits.
Earlier this month, Beckwith told Stockhead that Hemi also opened up a new style of mineralisation that nobody had found in the Pilbara before, highlighting that the region remained largely unexplored.
