NickelSearch dials in on main source at Sexton with massive sulphide hits

Assays confirm massive nickel sulphide mineralisation at Sexton
Greenfield drill program planning is underway to test a number of the Priority 1 nickel sulphide targets
Planning is underway for further drilling at Sexton to vector in on potential higher grades and thicker zones

Latest diamond drilling confirms massive nickel sulphides at Sexton — part of the Carlingup project – where NickelSearch believes it is vectoring in on “the main source”.

NickelSearch’s strategy is to identify high grade nickel sulphides to complement the existing shallow, large-scale nickel sulphide resource base at Carlingup (11.6Mt @ 0.56% Ni for 65kt contained nickel.)

The results from Sexton – a priority target — included 1m at 1.26% nickel, 0.19% copper from 132.5m and 1m at 0.76% nickel, 0.23% copper from 148.5m, validating the massive sulphide visuals previously logged.

Since Sexton has been interpreted as a remobilisation of mineralisation, likely from a primary nickel source, NickelSearch (ASX:NIS) will now use drill results combined with geophysics to vector in on the motherlode.

“We know from the DHEM surveys that the conductive plates continue as far as we can assess with the survey tool, meaning the mineralisation is open to us down-plunge,” NIS MD Nicole Duncan says.

“This alignment of the conductive plates at Sexton with confirmed mineralisation is a solid basis on which to test for further positive results beyond the limit of the DHEM surveys.”

DHEM maps sub-surface changes in electrical conductivity and is a useful tool for finding nickel sulphides.

Previous explorers missed paydirt at Sexton

Duncan says Sexton was identified with historical drilling, but it is becoming clear that the plunge was not correctly interpreted, the structure was missed, and hence the target was abandoned.

“Armed with fresh analysis performed since ASX listing, NickelSearch has been able to reconsider the historical information, and each of the six holes we have drilled at Sexton has intercepted nickel sulphide,” she says.

“This gives us confidence to continue our work on other greenfield targets across Carlingup, plus also plan further drilling at Sexton to vector in on potential higher grades and thicker zones.”

What’s next?

A greenfields drill program planning is underway to test several additional priority 1 nickel sulphide targets at Carlingup, with targets Lipple and Wadley to be tested first, scheduled to start in early October.

The exploration team will also review historic electromagnetic surveys at the B1 target and consider the opportunity to conduct further ultrafine soil sampling in the target area, to test areas where the sulphides may have accumulated.

At the same time, lithium rock chip sampling program continues, targeting priority areas defined by a recent desktop study, with samples submitted to the lab for assaying.
