Western Star Resources Inc. (CSE: WSR) (OTC: WSRIF) announced results from a high-resolution UAV magnetic geophysical survey completed across its White Star Tungsten Project in Elko County, Nevada. The survey, the first modern geophysical dataset acquired over the property, was designed to identify prospective targets and improve understanding of structural controls on mineralization.
The survey processed Total Magnetic Intensity (TMI), First Vertical Derivative (1VD), Second Vertical Derivative (2VD), and Analytical Signal (AS) products. Key findings include a northwest-southeast-trending magnetic lineament associated with the historical Batholith mine and adit, along with several comparable geophysical features elsewhere on the property. A broad magnetic high in the western portion suggests a previously unmapped extension of intrusive granite (quartz monzonite) interpreted to be associated with tungsten-bearing skarn mineralization. This intrusive body is adjacent to mapped carbonate units, defining a new area prospective for contact skarn-hosted tungsten mineralization. Multiple magnetic lineaments interpreted as fault and fracture zones may have acted as fluid pathways for mineralization.
CEO 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.”
Previously, only low-resolution data from 1967 (1-mile line spacing) existed. The UAV survey, flown with specifications matching the recently completed Rowland survey, allows for integrated district-scale interpretation across the consolidated Jarbidge-Charleston tungsten footprint. 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 geophysical results will be integrated with pending rock-chip and soil geochemistry to guide follow-up exploration design and refine potential drill targets. The combined White Star and Rowland dataset is undergoing geophysical inversion, with results to be announced once completed. This integration will provide a modern geophysical framework for 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. Data processing and gridding were performed using Geosoft Oasis Montaj by East Coast Consulting. Diurnal corrections, lag and heading bias corrections were applied. Filtered derivative products were computed from corrected TMI data, and grids were generated with a cell size of approximately one-third of the flight line spacing.
The scientific and technical information has been reviewed and approved by Jasper Mowatt, MIMMM and MAusIMM, a Qualified Person as defined by National Instrument 43-101.
