NickelSearch has identified multiple high-priority targets from preliminary analysis of recent helicopter-borne electromagnetic and magnetic surveying at its Carlingup nickel sulphide project.

 The survey over the entire project area identified 13 EM targets along the Carlingup Trend that hosts the RAV-1, RAV-4, RAV-4 West and RAV-8 nickel sulphide deposits and a further 16 EM targets along the underexplored Ravensthorpe Range Trend.

Of these 29 targets, 15 were classified as Priority 1 targets due to their coincident geochemical anomalism and geological setting.

NickelSearch (ASX:NIS) highlighted an EM anomaly at Sexton as a high priority greenfields target due to its association with soil geochemistry that is an indicator of nickel fertility.

It added that the coincidence of anomalies with known deposits and high priority prospects confirmed that EM is a valid method for identifying additional nickel sulphide discoveries.

The EM anomalies also show a district-scale association with specific ultramafic units and linear magnetic features along the Carlingup and Ravensthorpe Range trends.

“We are very pleased to announce an exciting new pipeline of targets arising from analysis of the airborne EM and magnetic survey conducted over the entire Carlingup project area,” managing director Nicole Duncan said.

“NickelSearch is committed to greenfield exploration and is utilising airborne EM and ultrafine soil geochemistry to screen the entire Carlingup land package for the first time.

“Identification of these new targets supports the company’s exploration strategy.”


Survey details

The Xcite airborne survey completed by NRG Australia in January 2022 involved a total of 955 line-kms of airborne EM and magnetic data flown using line spacings of between 50m to 200m.

Targets were ranked based on their EM and magnetic characteristics, combined with soil and rock geochemistry, digital elevation modelling, radiometric and satellite imagery, and interpreted geology.

Subsequent target definition work is in progress, with the recent completion of 2,312 systematic ultrafine soil geochemical samples that cover a 15km strike of the Carlingup trend.

NickelSearch will carry out a second phase of soil sampling along the Ravensthorpe Range where several EM targets have been identified associated with the host ultramafic unit.

Ground-truthing of priority targets will be carried out once access with relevant stakeholders can be secured.
