NickelX Ltd (ASX:NKL) has uncovered sizeable electromagnetic anomalies with heavy nickel upside at its Dalwallinu Nickel Project in Western Australia.
The ambitious explorer is pursuing Julimar-style mineralisation in the state’s West Yilgarn region and identified the anomalies using moving loop (MLEM) and fixed loop (FLEM) survey techniques.
By modelling the electromagnetic data, NickelX has pinpointed two high conductance plates, dubbed DEM1 and DEM 2 — each offering distinct potential for nickel mineralisation.
Hunt for Julimar-style minerals
NickelX managing director Matt Gauci said: “The MLEM and FLEM survey results confirm the prospectivity of Dalwallinu to host massive sulphide mineralisation.
“Combined with high-tenure nickel, copper and platinum group element (PGE) geochemical results, … [we are using] modern geophysics and detailed sampling to further refine drill targets at Dalwallinu, where the company is seeking Julimar-style mineralisation.”
A closer look
The DEM1 target is a 210-metre by 270-metre plate with moderate conductance situated along a moderate magnetic trend that dips steeply to the west. The model suggests the conductor's top lies roughly 100 metres below the surface.
On the other hand, DEM2 has been modelled as a high conductance 65-metre by 65-metre plate at around 30 metres deep.
While this plate satisfies the majority of the response from the central lines, there is evidence that the anomaly extends along strike in both directions as a weaker anomaly or at depth.
Interestingly, conductance at both DEM1 and DEM2 aligns with massive sulphide mineralisation, making these newly discovered anomalies compelling targets for Julimar-style nickel-copper-PGE mineralisation.
With Dalwallinu covering 86 square kilometres of prospective tenure in the Barra Barra Greenstone Belt — just 150 kilometres from Julimar — this accessible private farmland presents strong exploration upside.
