Auroch Minerals Intersects Nickle Sulphides at new Leinster Project Prospects

THE DRILL SERGEANT: Auroch Minerals (ASX: AOU) reported assay results from diamond drilling completed at the Woodwind and Percussion prospects at the company’s 100 per cent-owned Leinster nickel project in Western Australia.

Auroch Minerals received assay results for four of five diamond drill-holes drilled to test the potential of the Woodwind and Percussion prospects.

The two prospects are located directly along strike from the Horn prospect, where previous drilling delineated shallow high-grade nickel sulphide mineralisation.

The prospects are defined by aeromagnetic high anomalies that Auroch consider being very similar to that which defines the Horn prospect, as such the company has defined them to be high-priority drill targets.

Results include:

72 metres at 0.46 per cent nickel from 212m, including 4m at 0.61 per cent nickel from 233m and 14m at 0.57 per cent nickel from 258m;

8m at 0.30 per cent nickel from 296m to EOH within elevated nickel values (>0.25 per cent nickel) and observed disseminated nickel sulphides over 88m from 216m; and

2m at 0.45 per cent nickel from 388m, including 1m at 0.61 per cent nickel from 389m.

Auroch noted the results highlight the aeromagnetic trend at Leinster is coincident with a thick package of fertile, nickel sulphide -bearing ultramafic rocks.

“This has been an exceptional start to our regional exploration at the Leinster project,” Auroch Minerals managing director Aidan Platel said in the company’s ASX announcement.

“After outstanding shallow high-grade nickel-copper sulphide results from drilling at the Horn prospect in late 2020, we were intrigued by what the magnetic anomalies along strike from the Horn may hold, most of which had never seen a drill-hole.

“The results from just our first four drill-holes have already shown that these aeromagnetic highs at the Woodwind and Percussion prospects do indeed define thick fertile ultramafic units that have cumulate ultramafic phases with disseminated nickel sulphides – that is, exactly the geology seen proximal to the massive nickel sulphide mineralisation at Rocky’s Reward and Perseverance, one of the largest nickel sulphide deposits in the world that is only 35 kilometres to the north of our Leinster project.

“The diamond drilling has been particularly important for our geology team to see these all-important textures and structures, and has helped them to identify the overturned structural setting at Woodwind, similar to that of the Horn.

“The presence of nickel sulphide stringers in hole HNDD0011 suggest we are getting closer to significant accumulations of nickel sulphides, and we are eager to see what the pending DHEM and assay results will tell us as we attempt to vector in on massive nickel sulphide mineralisation in this highly-prospective trend.”
