Drilling is set to test a large gravity anomaly at the Ragless Range prospect where previous drilling intersected shallow, high-grade zinc mineralisation up to 12.8m at 4.96% zinc from 53m.

Auroch Minerals has started earthwork activities in preparation for a three–five-hole diamond drilling program at the Ragless Range Zinc target within the wider Arden Project in South Australia.

The drilling program, which Auroch (ASX:AOU) plans to start this week, will test sedimentary exhalative (SEDEX) zinc mineralisation previously identified in the company’s 2018 diamond drill programme.

Results at the time from RRDD007 intersected 12.8m at 4.96% zinc from 53m, including 3.65m at 15.47% zinc from 62.15m.

Drilling will focus on a significant gravity anomaly extending over 2km in the Ragless Range syncline west of previous drill holes.

Auroch believes the gravity anomaly may be indicative of thickened mineralised horizons of high-density, high-grade zinc mineralisation.

‘A very exciting drill target’

AOU managing director Aidan Platel said: “Our first-pass drilling of the target area successfully intersected some very high-grade zinc mineralisation, and our follow up geophysical surveys have delineated a strong anomaly that warrants drill-testing.

“The high-grade and potential scale of this zinc mineralisation make it a very exciting drill target and we look forward to kicking off the drill program later this week.”

“At Nepean we have initiated the second drill-hole into the Nepean Deeps Target which has been designed to test the uppermost EM conductor 1A/1B.

“This conductor has great potential to represent significant nickel sulphide mineralisation below the historic Nepean mine workings, and we look forward to seeing what the drilling will encounter.”

Auroch says previous mineralisation intersected in the shallow drilling and outcropping gossans may have been restricted to horizons within the narrower fold limbs and believes that testing the interpreted anomaly at depth is therefore warranted.
