Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) announced results from a high-resolution UAV magnetic geophysical survey completed at its White Star Tungsten Project in Elko County, Nevada. The survey, the first modern geophysical dataset for the project, was designed to identify prospective targets and improve understanding of structural controls on mineralization. Results will be integrated with ongoing rock-chip and soil geochemical sampling.
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. Additionally, multiple magnetic lineaments trending NE-SW and NW-SE were identified, 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. Comparable geophysical features were identified elsewhere on the property, suggesting additional mineralized zones. CEO Blake Morgan stated, '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 favorable setting for tungsten skarn mineralization.'
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 hosting discrete magnetic features, and the historical open pit area where contact geology may continue beneath Quaternary cover. The results will guide design of a follow-up exploration program and refine potential drill targets.
The White Star survey was flown to the same specifications as the recently completed Rowland UAV magnetic survey, enabling the two datasets to be processed as a single district-scale product spanning the consolidated Jarbidge-Charleston tungsten footprint. A combined dataset is undergoing geophysical inversion and will be announced when completed. This integration will support district-scale targeting between the White Star workings and historical workings at the adjoining Rowland Tungsten Property.
Quality assurance and quality control protocols were applied during data collection, with final processing and gridding performed using Geosoft Oasis Montaj by East Coast Consulting. Diurnal corrections, lag and heading bias corrections were applied, and filtered derivative products including Analytical Signal and First & Second Vertical Derivative were computed. Grids were generated using the minimum curvature method with a cell size of approximately one-third the flight line spacing.
