NickelX now has a clearer idea where to search for Julimar-style mineralisation at its Dalwallinu project in the West Yilgarn, WA, after defining multiple geochemical anomalies over a combined 12km strike.

The recently completed infill auger drilling soil sampling program was undertaken on a 50m by 50m spacing to better define four priority targets that were previously identified by a more broadly spaced 100m by 200m soil sampling program and recent airborne magnetic survey.

NickelX (ASX:NKL) noted that the highest priority target assays host some of the highest platinum group element (PGE) assays of 73.7 parts per billion platinum and palladium in the West Yilgarn along with significant and coincident anomalous values for nickel and copper (466 parts per million and 843ppm respectively).

The high priority geochemical targets also complement the recently modelled Moving Loop Electromagnetic (MLEM) and Fixed Loop Electromagnetic (FLEM) bedrock conductors at DEM1 and DEM2, also some of the strongest bedrock conductors (16,850 Seimens) in the West Yilgarn, which are prospective for massive sulphides

Like looking in a mirror

Dalwallinu is a lookalike of the Chalice Mining’s world-class Julimar nickel-copper-PGE discovery, which is also located within the emerging West Yilgarn region.

“The team are very excited by the combined 12 kilometres of strike of geochemical anomalies recently defined, which confirms the significant prospectivity of the Dalwallinu project for nickel-copper-PGE mineralisation,” managing director Matt Gauci said.

“This, combined with the recent Drone Magnetic Survey and MLEM and FLEM Survey results, has now identified numerous high priority targets, prospective for Julimar type Nickel-Copper-PGE mineralisation.”

Access and Exploration Agreements have also been signed with four relevant Dalwallinu landowners for future exploration drilling and development activities.

Auger soil sampling

The infill auger drilling program collected 873 samples from the four priority areas, which returned results consistent with the earlier regional survey results.

It also confirmed that these target areas are anomalous in nickel, copper and PGE, allowing for further refinement of the target zones.

NickelX adds that the soil geochemical and FLEM anomalies are consistent and occupy the same target horizon outboard of, and folded around, an interpreted synformal structure defined by the close spaced drone aeromagnetic anomaly.

This horizon containing the geochemical and geophysical anomalous areas is interpreted as a possible sill sitting stratigraphically below a magnetic banded iron formation.

Its anomalous geochemistry and geophysics, as it is folded and repeated, gives a combined strike of some 12 kilometres of target trend to explore.

Work ahead

The company is currently organising a Program of Works with WA’s Department of Mines, Industry Regulation and Safety for a planned maiden 2,500m reverse circulation and diamond drill program.

It has also started due diligence and engagement with the Local Aboriginal Cultural Heritage Services (LACHS), when available under the soon to be effectuated Aboriginal Cultural Heritage Act (2021).
