Moho Resources Ltd (ASX:MOH) has identified high nickel sulphide potential after receiving results from exploration at the Silver Swan North project in Western Australia.
The potential has been revealed by surveys, mapping. a reassessment of soil geochemistry and studying results from an historical drill hole.
Historical hole
This hole intersected 5 metres of sediment from 255 metres containing 10-40% sulphides, or up to 0.1% nickel before ending in ultramafic rocks.
A downhole EM survey at the time detected a large, late time off-hole response towards the bottom and south of the drill-hole but this was not followed up.
Survey identifies conductors
Moho’s high sensitivity low temperature SQUID EM survey has identified three new conductors near this hole, which represent drill targets.
Reassessment of soil geochemistry by Moho’s consultant Richard Carver has also highlighted several areas of nickel anomalism.
A detailed ground gravity survey completed last quarters has highlighted an untested gravity high associated with the untested historical EM anomaly.
Noisy nickel neighbours
These results have proved encouraging for the company as ultramafic rocks within the Black Swan Komatiite Complex (BSKC) host a number nickel sulphide mines.
These include the Silver Swan, Black Swan and Cygnet nickel sulphide deposits as well as Poseidon Nickel Ltd’s Black Swan nickel processing and concentrator facility.
Drilling is planned
Moho plans to drill up to five reverse circulation holes to test the new EM conductors in late February, subject to approval from the Department of Mines Industry and Safety.
The SQUID EM survey has been extended over anomalous Target Zone 4 and to the boundary with Poseidon’s mining lease with a further extension planned over other areas.
Moho will also undertake a major geochemical and straitigraphic aircore drill program across the northern area to identify suitable host rocks for nickel sulphide mineralisation under cover.
