Nickel X Ltd (ASX:NKL) has completed and processed data from, a detailed close spaced drone Magnetic Survey over the Dalwallinu project, refining targets where the company is seeking Julimar Style Nickel-Copper-PGE mineralisation in Western Australia.
The detailed close spaced drone magnetic survey combined with historical and current soil samples, points to some very well-defined exploration targets, seeking Julimar Style Nickel-Copper-PGE mineralisation,” Managing Director Matt Gauci said.
“The new magnetic data indicates that the Barra Barra Greenstone Belt intrusive targeted for Ni-Cu-PGE mineralisation represents a folded tabular body, either originally a dyke or a sill. The exploration team will now progress to a closer spaced soil sampling program over the newly refined targets, prior to a maiden drill programme.”
The company contracted SensorEM to carry out a drone airborne magnetic survey over the entire Dalwallinu project tenement E70/5398. The survey was flown on 50m spaced lines, oriented east-west at a sensor height of 40m above ground. In all 771 line-kilometres of magnetic data was obtained over the project. The new magnetic data represents a far superior product to the previous regional magnetic data for target delineation on the project.
Preliminary interpretation of the new magnetic data indicates that the Barra Barra Greenstone Belt intrusive targeted for Ni-Cu-PGE mineralisation represents a folded tabular body, either originally a dyke or a sill. The body appears to be tightly folded, with a western antiformal structure plunging steeply to the north in the west of the tenement, and a shallowly north plunging synformal structure in the east of the project.
Overlaying the previously reported auger geochemistry data on the new magnetic data highlights an apparent intrusive body horizon just outboard and bordering the main folded magnetic strata, that is anomalous for Ni-Cu-PGE.
This may represent a sill-like body lying structurally below and folded with the magnetic strata. Four areas are highlighted with anomalous metal values in the auger geochemistry data. These areas represent priority targets for follow-up exploration, as does investigation of the margins of the antiform folded magnetic body in the west of the project.
Planning is currently underway to infill auger geochemistry over these four priority areas with follow up ground electromagnetic surveys to follow. The results of the infill geochemistry and EM will be targeted with a maiden drilling programme once appropriate permitting is in place.
