NickelSearch says downhole electromagnetics (DHEM) surveys at the Sexton prospect at its Carlingup project in WA show high to very high conductive sources – confirming the prospectivity for massive sulphides.

The DHEM plates extend 80m down dip and >150m down-plunge from RC drilling last month that intersected 6m of massive and matrix sulphides from 149m in drill hole 23NRC012.

Drill hole 23NRC012 has also been checked with a Portable X-ray fluorescence (pXRF) device which suggests the sulphides are nickel bearings.

However, the company cautions that pXRF results should never be considered a proxy or substitute for laboratory analysis that is required to determine grades and widths reported from visual or pXRF logging.

Assay results from the recent RC drilling are pending.

Potential for a ‘significant’ nickel discovery

The DHEM plates are also coincident with historic nickel sulphide intersections, giving NickelSearch (ASX:NIS) confidence in the extensional targets for planned follow up drilling scheduled for Q2 CY23.

“We are excited to see strong indicators that Sexton has the potential to progress into a significant nickel discovery,” MD Nicole Duncan said.

“The modelled DHEM plates and visual mineralisation intercepted in the maiden drill program suggest mineralisation extends at depth and down-plunge.

“The very high conductivity of the DHEM plates also highlights the potential to intersect a high-grade channel, which will be a focus for follow-up drilling.”

Drilling planned across 30+ targets

DHEM plates are coincidental with an historic drill section of 2m at 1.2% nickel and 0.17% copper from 98m, and recent sulphide intersections announced 2 February 2023.

The plunge orientation is also very similar to that seen in the RAV8 deposit, 3.5km to the east, and has been interpreted as indicating the Sexton plates are following regional trends rather than just apparent dip.

“The recent drilling results and success of the DHEM surveys give us confidence in continuing with systematically testing our 30+ greenfields targets defined across Carlingup,” Duncan said.

“We look forward to commencing follow-up drilling at Sexton and maiden RC and Diamond drill programs at greenfields targets Lipple, Wadley and John Ellis West in Q2 CY2023.”
