Auroch’s got boots on the ground at Leinster testing top-ranked nickel sulphide targets

A two-hole diamond drilling program has kicked off to test a DHEM conductor detected in the first phase of regional drilling at the Brass prospect.
A structural offset or repetition of the massive nickel sulphides present at the Horn deposit on the eastern Woodwind Prospect will also be tested after top ranked targets were identified by external consultants in a recent technical review.
At the Woodwind prospect northwest of the Horn deposit, previous diamond drilling returned anomalous nickel intersections in multiple drill-holes, including the highly encouraging result of 72m at 0.46% nickel from 212m in HNDD008.
Drilling will test for the continuation of the overturned komatiite sequence and/or a potential repeat of the prospective stratigraphy through recumbent folding.
At the Brass prospect, an anomalous nickel result of 1m at 0.56% nickel from 159m on a prospective basal ultramafic – basalt contact within WDRC008 is coincident with an off-hole DHEM conductor with a moderate to high conductance of 3,000-6,000S centred just north of the drill-hole.
Auroch Minerals (ASX:AOU) says the Brass001 hole will aim to intersect the three modelled plates between 195-220m depth to test for potential massive nickel sulphide mineralisation.
“The geological team are excited to have a diamond rig return to Leinster – the known sulphide mineralisation at Horn is significant not only for its high-grade nickel content, but also for its elevated copper, cobalt and PGEs content as well its low magnesium to iron ratios,” AOU managing director Aidan Platel said.
“The potential for similar nickel sulphide mineralisation to be discovered at Woodwind and Brass remains high and this programme will aim to test the top ranked targets.”
Seismic Drilling Australia are conducting the program with completion set for three weeks, followed by logging, sampling and DHEM surveys of each hole.
Partial drill results have been received from the two-hole diamond programme completed at the Ragless Range Zinc prospect of the company’s Arden Zinc-Copper Project in South Australia.
Results confirmed the anomalous zinc-manganese clay-rich zone in hole RRDD011, including 2.15m at 0.57% zinc and 5.5% manganese from 450.95m; however neither drill-hole had any significant economic intersections to report.
AOU is currently planning the next drilling phase at Ragless Range to follow up on the IP anomalies and the possible extensions to the high-grade zinc mineralisation in drill-hole RRDD007 which intersected 12.8m at 4.96% zinc from 53m, including 3.65m at 15.47% zinc from 62.15m.
