Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) has released results from a high-resolution UAV magnetic geophysical survey at the White Star Tungsten Project in Elko County, Nevada, marking the first modern geophysical dataset acquired over the property. The survey, designed to identify prospective targets and improve understanding of structural controls on mineralization, has delineated a broad magnetic high interpreted as an extension of the intrusive granite associated with tungsten-bearing skarn mineralization.
The survey was flown at the same specifications as the recently completed Rowland UAV magnetic survey, enabling integration into a contiguous district-scale magnetic product across the consolidated Jarbidge–Charleston tungsten footprint. Blake Morgan, CEO and President of Western Star, stated that the results complete the district-scale magnetic coverage that the property consolidation was intended to unlock, and the interpreted intrusive body has generated a significant new area of interest where granite-carbonate contact may host tungsten skarn mineralization.
Key findings include the identification of multiple discrete magnetic bodies within and adjacent to the mapped quartz monzonite intrusion (Kqm), which the technical team interprets as apophyses of the intrusion. Each apophysis represents additional prospective intrusive–host rock contact. The dataset also resolves NE–SW and NW–SE trending magnetic lineaments interpreted as high-angle fault and fracture zones favorable as fluid pathways for tungsten-bearing hydrothermal fluids.
Four target zones have been defined for follow-up: the central Kqm–Pzt contact north of the Batholith Mine, considered the highest priority; a northern Pzt body within the northern Kqm; a southern limestone corridor with multiple small Pzl limestone bodies; and the historical open pit area, where coherent magnetic character suggests buried contact geology. The historical Batholith mine and adit are situated along a northwest-southeast-trending magnetic lineament within a subtle magnetic low, and comparable features have been identified elsewhere on the property.
The geophysical results will be integrated with pending rock-chip and soil geochemistry from the White Star and Rowland field program to define priority targets and inform the design of subsequent exploration. The combined district-scale dataset from White Star and Rowland is undergoing geophysical inversion and will be announced once completed, providing the first modern geophysical framework across the two mining districts.
