Targeting Eye-Like Magnetic Feature
S2 Resources Ltd’s (ASX:S2R) first moving loop electromagnetic (MLEM) survey on the company’s exploration licence E28/2792 in the Fraser Range of Western Australia has revealed a large strong electromagnetic (EM) conductor associated with the recently identified eye-like magnetic feature.
The company recently undertook a MLEM survey over the eye-like magnetic feature on recently granted exploration licence E28/2792, where it is exploring for magmatic nickel sulphides.
Executive Chairman, Mark Bennett, said the survey identified a conspicuous anomaly on initial 400 metre spaced lines and subsequent 200 metre spaced infill lines. Such anomalies indicate the presence of conductive material which could be nickel sulphide mineralisation, barren (iron) sulphides, graphite bearing rock, or even hypersaline groundwater.
Modelling of the data by Newexco geophysical consultants has identified a discrete, highly conductive elongate rectangular body which dips steeply west over a vertical interval of 160 metres and plunges to the northeast for a distance of 800 metres.
The up-dip and up-plunge tip of this body commences at a depth of 200 metres below surface and deepens down plunge to the northeast.
Mr Bennett said the anomaly stands out clearly from the background with no other responses of note, and the observed response profiles fit very well with the theoretical responses, indicating a good fit to, and high degree of confidence in the model.
He added that Very little is known about the geology of the area because of lack of outcrop, but the conductor sits within an interpreted prospective corridor of ultramafic intrusives and minor nickel sulphide occurrences previously identified by other companies.
The tenement is entirely covered by recent transported sediments, rendering surface geochemical sampling ineffective, so no geochemical survey has been done.
Also, the top of the conductive body is located 200 metres below surface, so surface geochemistry is likely to be irrelevant. The target is sufficiently well defined to drill as soon as heritage and drilling approvals have been obtained.
