Moho Resources Ltd (ASX:MOH) has completed a new phase of reverse circulation (RC) drilling, targeting coincidental nickel-copper anomalies at Dukes and T3/T4 prospects within the Silver Swan North Nickel Project in Western Australia.
In total, the company’s RC program included 10 holes across 1,806 metres at Silver Swan North.
At Dukes, a soil sample program outlined a coincident nickel-copper anomaly overlying a magnetic high which is interpreted as ultramafic lithologies.
While the two holes at T3 intersected very few ultramafic lithologies, the two southernmost holes at T4 intersected 80-100 metres of ultramafic flows with spinifex and cumulate textured komatiite.
This phase of drilling was designed to further unlock the nickel potential of Silver Swan North, reflecting the company’s commitment to comprehensively test the project area for komatiite-hosted nickel sulphides.
“Unlocking the potential”
Moho managing director Ralph Winter said: “The Moho team eagerly awaits the assay results of this program, with the RC drilling further unlocking the potential for nickel sulphides discovery at Silver Swan North.
“This program further bolsters the company’s critical minerals strategy and increases the strength of our exceptional project portfolio.”
Drilling at Dukes
At the northern end, all three holes intersected ultramafic lithologies with minor disseminated sulphides overlain by massive gabbro
At the southern end, all four holes at southern end intersected the same ultramafic lithologies over a width of more than 200 metres, again overlain by massive gabbro.
Drill hole SSMH0150 intersected a more gabbroic lithology with more than 10% disseminated sulphides from 53 metres to 66 metres within the ultramafic sequence.
The ultramafic appears to be a layered ultramafic intrusive sill rather than an extrusive ultramafic volcanic.
Drilling at T4 target
Nickel target areas T3 and T4 are about 10 kilometres to the south and less than five kilometres east of the Silver Swan Nickel mine.
The area was tested with RAB drilling by NiQuest more than 10 years ago and several coincidental nickel-copper anomalies which were intersected have not been properly followed up.
Two holes intersected 80 to 100 metres of ultramafic flows with spinifex and cumulate textured komatiite, including hole SSMH0157.
Hole SSMH0157 was abandoned due to excessive water inflow after intersecting about 20 metres of 5% to 10% disseminated sulphides at the bottom of the hole.
