NickelSearch Limited announced that assays have been received for the recent Reverse Circulation (RC) drilling completed at the Company's Carlingup Nickel Sulphide Project (Carlingup or the Project) near Ravensthorpe, Western Australia. The assays confirm that the massive sulphides seen in the drilling at the Company's high priority target Sexton contain significant nickel mineralisation, with DHEM surveys showing that the mineralisation extends down-plunge and remains open. Four RC holes were drilled at Sexton, and each hole intersected massive sulphides that are nickel-bearing.

These intersections are also coincidental with the historic drill section of 2m at 1.2% Ni and 0.17% Cu from 98m. Assay results confirm nickel mineralisation across all four holes. The logged results show an increasing width of nickel mineralisation as drilling progresses down-plunge.

Drilling has intersected interpreted thin sheet flows in a flanking Komatiitic flow environment. This raises the possibility of a thicker massive sulphide filled channel nearby. Overall, the strike length of Ni-bearing mineralisation at Sexton now extends to 150m and is interpreted to be open.

As well as the holes shown on the cross-section in Figure 3, 23NRC009 also hit 3m of massive sulphides at 1.11% nickel from a shallow depth of 39m. This location suggests that 23NRC010 was just to the north of the main trend, and that this could extend to surface by following the trend up-plunge. Geochemical analysis by Dr Nigel Brand confirms the visually logged interpretation and explains that the ultramafic olivine-saturated magma has melted and adsorbed the adjacent sulphidic sediments as they flowed over, thus providing the necessary sulphur source.

The thin lava flows at this location are what drives the fine-grained crystallisation of pyrrhotite with elevated nickel values, because there is insufficient time for the fractionation of distinct nickel sulphides like pentlandite before the melt cools and crystallises in a channel or embayment. Geophysics from the DHEM surveys show small conductors on hole at the mineralised intervals, and also a much larger plate modelled on and off hole at the lower, nickel-bearing interval. This plate has a high conductance core, modelling up to 50,000 Siemens continuing down-plunge, beyond the effective range of the survey to measure.
