THE DRILL SERGEANT: Argent Minerals (ASX: ARD) is busy preparing the next phase of deep diamond drilling for the company’s Kempfield polymetallic project in New South Wales.
The company has designed the upcoming holes to test a recently validated Volcanogenic Massive Sulphide (VMS) deposit model, which it considers to demonstrate potential for depth extensions to mineralised lenses below the known deposit.
“Following the recent validation of Argent’s hypothesis for the formation and structure of the deposit and the potential increased ‘size of the prize’, five additional diamond holes have been designed to significantly extend the reach of the Kempfield deep diamond drilling program,” Argent Minerals managing director David Busch said in the company’s announcement to the Australian Securities Exchange.
“Four of the new holes will focus on testing the depth extensions of the known mineralisation at Kempfield that are predicted by the recently validated deposit model.
“An additional hole has also been designed to complement further drilling work already planned, targeting new lenses of high-grade base and precious metal mineralisation.”
Holes 5 and 6 have been designed to complement Hole 4 in testing for depth extensions of the southern portion of Lens 3 in an area where previous drilling intersected 18 metres at 9.8 per cent lead-zinc, 113 grams per tonne silver and 0.26g/t gold from 85m, including 5m at 17.9 per cent lead-zinc, 256g/t silver and 0.34g/t gold from 85 m.
This area also includes a previous intersection of: 48m at 4.33 per cent lead-zinc, 43g/t silver and 0.6g/t gold from 56 m, including 14m at 5.2 per cent lead-zinc, 64.5g/t silver and 1.5g/t gold from 72m.
Holes 4, 5, 6, 8 and 9 will also test for depth extensions of Lens 2, and Hole 4 has been extended to 600m to test for depth extensions to the southern portion of Lens 1.
“NSW Government-sponsored Holes 3 and 4 will be drilled next to test for interpreted Lens 4 and the northern strike extension of Lens 3, their planned depths now extended to 550 and 600 metres respectively,” Busch continued.
“In addition to drill-testing specific targets, Holes 1 to 4 were also designed to provide the deepest geophysics coverage of the Kempfield site to date.
“Downhole electromagnetic (EM) surveys are vastly superior to ground or airborne surveys for depth, sensitivity, discernment of targets from manmade structures, and 3D accuracy in determining response locations.
“Downhole surveys will be performed on the holes to identify any base metal conductors within the designed survey pattern covering a significant area of up to 600,000 square metres and depths of up to 450 metres below the surface.”
