Explorers love when surveying coincides with known mineralisation and NickelSearch is no exception with DHEM surveying confirming the extent of previously modelled conductive plates at its Sexton project.

Down-hole electromagnetic surveying of the 23NRD028 and 23NDD030 diamond holes, which intersected visual massive sulphide mineralisation in both the Upper Mineralised Horizon (UMH) and Lower Mineralised Horizon, found conductive plates with conductance of up to 30,000 Siemens that extend to the survey limits both up and down plunge.

The confluence of surveying results with known mineralisation is a great result as it is a strong indicator that the same technique or survey type can be applied elsewhere in the area to find more mineralisation.

NickelSearch (ASX:NIS) managing director Nicole Duncan is certainly encouraged by the alignment of the conductive plates at Sexton with known mineralisation – especially since there’s potential for further positive growth beyond the limit of testing.

“It is particularly pleasing to see the conductive plates continuing as far as we can assess with the DHEM survey,” she added.

“We intersected visual sulphides, including massive sulphide mineralisation, in our June 2023 diamond drilling at Sexton and overlaying this information from the DHEM surveys gives us confidence in the prospectivity of Sexton.

“The visual nickel sulphide mineralisation intersected in the diamond drilling is sitting in a structure located at relatively shallow depths starting quite close to surface at ~40m and continuing to ~145m depth. We look forward to assay results in the coming weeks.”

 

DHEM results

Recent diamond drilling had targeted two distinct bodies of mineralisation encountered in earlier reverse circulation drilling which have since been corroborated by the recent DHEM surveys.

The newest results show that mineralisation continues to the boundary of the survey limits, with the constrained models also showing that mineralisation is in a corridor roughly 80m wide.

So far, the combination of diamond drilling (totalling four holes now) and DHEM has allowed the company to define three conductive horizons that dip shallowly to the south-east.

Additionally, there is an offhole conductor below 23NRC011 that is untested, and another centred below 23NDD030 that has not been closed off.

 

Upcoming work

NickelSearch is currently waiting on assay results for the two diamond holes, which will be combined with the DHEM data to generate follow-up drill targets to extend mineralisation.

It will also consider historical EM surveys at B1 and consider the opportunity to conduct further ultrafine soil sampling in the target area.

This could result in the consideration of further drilling within the B1 mineralised horizon to test areas where sulphides may have accumulated.
