Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) has announced the results of a high-resolution UAV magnetic geophysical survey at its White Star Tungsten Project in Elko County, Nevada. The survey, the first modern geophysical dataset acquired over the property, was designed to refine the geological model, identify prospective targets, and improve understanding of structural controls on mineralization. The results are being integrated with ongoing rock-chip and soil geochemical programs.
The survey processed Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS) products. Key findings include the identification of a broad magnetic high in the western portion of the property, interpreted as a previously unmapped extension of the intrusive granite (quartz monzonite) associated with tungsten-bearing skarn mineralization. This intrusive body lies adjacent to mapped carbonate units, defining a new area prospective for contact skarn-hosted tungsten deposits.
Multiple magnetic lineaments trending NE-SW and NW-SE have been interpreted as fault and fracture zones that may have acted as pathways for hydrothermal fluids. The historical Batholith mine and adit are situated along a NW-SE-trending magnetic lineament within a subtle magnetic low, and several comparable geophysical features have been identified elsewhere on the property.
The survey also resolved multiple discrete magnetic bodies within and adjacent to the mapped quartz monzonite, which the technical team believes represent apophyses of the intrusion. Each apophysis adds prospective intrusive-host rock contact length. Four target zones have been defined for follow-up: the Central Kqm–Pzt contact north of the Batholith Mine, a Northern Pzt body within the northern Kqm, a Southern limestone corridor, and the Historical Open Pit area.
The White Star UAV magnetic survey was flown to the same specifications as the recently completed Rowland UAV magnetic survey, enabling the two datasets to be processed together as a contiguous district-scale magnetic product spanning the consolidated Jarbidge–Charleston tungsten footprint. The combined dataset is undergoing geophysical inversion and will support integrated targeting between the White Star workings and the Rowland Tungsten Property.
CEO and President Blake Morgan stated, "The White Star geophysical results provide the second component of the consolidated Jarbidge-Charleston dataset and complete the district-scale magnetic coverage that the property consolidation was intended to unlock. The interpreted intrusive body identified in the high-resolution magnetic data has generated a significant new area of interest, where the contact between the granite and surrounding carbonate rocks may provide a favourable setting for tungsten skarn mineralization."
The geophysical results will be integrated with pending rock-chip and soil geochemistry to define priority follow-up targets and inform the design of subsequent exploration phases. The scientific and technical information has been reviewed and approved by Jasper Mowatt, a Qualified Person as defined by National Instrument 43-101.
