Moho Resources Ltd (ASX:MOH)'s recent reverse circulation (RC) drilling to follow up a coincidental nickel-copper soil anomaly at the T4 target area, within the Silver Swan North Project, has been productive.
This phase of drilling was designed to further unlock the nickel potential of the project, backing the company’s commitment to test the project area for komatiite-hosted nickel sulphides.
Findings positive
Geological logging and pXRF analysis of samples from the program indicate the presence of magmatic nickel sulphides at the T4 nickel target.
The pXRF readings on several samples identified six anomalous zones at T4, with intercepts between 2 metres and 9 metres and more than 2,000 parts per million (ppm) nickel, coincidental with greater than 100ppm copper.
In particular, pXRF readings in hole SSMH0158, with the deepest intercept – 46 metres to 49 metres – included one metre of 3,333ppm nickel, 114ppm copper and 203ppm cobalt.
This last result is encouraging because the anomalous zone is at the base of the regolith and cobalt prices are riding high at the moment.
Assay results from the laboratory are pending. In the meantime, further exploration, including drilling across the targets, is planned.
Chasing the anomalism
“The pXRF readings from the recent T4 drilling are in line with previous drill results from historic drilling and confirm coincidental nickel and copper anomalism at the T4 target area,” managing director Ralph Winter said.
“The company keenly awaits the wet assay results from the lab as validation of the readings and is planning further exploration across the targets to further chase the indicative anomalism.”
Silver Swan North is 40 kilometres north of Kalgoorlie in WA and 5 kilometres west of the Silver Swan nickel mine.
Nickel target area T4 was tested with RAB drilling by NiQuest more than 17 years ago and several coincidental nickel-copper intersection anomalies were not followed up.
Next steps
The company will review assay results of drill samples when they’re back from the laboratory, re-assess historic electromagnetic surveys over the T4 target area and then plan an RC/diamond drilling program at T4 to further outline the distribution of magmatic nickel and copper sulphides within the komatiite.
