Western Star completes phase 1 work at Rowland

Mr. Blake Morgan reports

WESTERN STAR RESOURCES COMPLETES PHASE 1 EXPLORATION AT ROWLAND TUNGSTEN PROPERTY AND CONFIRMS THREE ZONES OF EXTENSIVE HISTORICAL TUNGSTEN WORKINGS

Western Star Resources Inc. has successfully completed phase 1 exploration at its 100-per-cent-owned, past-producing Rowland tungsten property in Elko county, Nevada, United States.

The phase 1 program comprised a high-resolution UAV (unmanned aerial vehicle) magnetic geophysical survey, focused soil geochemistry, rock-chip sampling and field checking of historical workings. Samples have been submitted to the laboratory and rush processing requested in order to return assay results as quickly as possible.

The phase 1 field program has materially increased the company's understanding of the property. Four discrete zones of extensive historical tungsten-bearing workings have been confirmed on the ground, all hosted within the same skarn-style geological setting as the originally targeted Rowland workings.

Key highlights:

  • Phase 1 exploration successfully completed at the Rowland tungsten property, comprising a property-wide UAV magnetic survey, focused soil geochemistry, rock-chip sampling and lidar target ground truthing.
  • Four discrete zones of extensive historical tungsten-bearing workings have been confirmed on the ground: Northern zones A and B, Central zone, and the original Rowland zone.
  • Northern zone B was the most significant historical development identified on the property. Field crews confirmed dilapidated wooden infrastructure consistent with a historical ore chute and several decommissioned shafts.
  • Rowland Main had multiple additional workings, trenches and surface disturbances confirmed on the ground, with extensive UV (ultraviolet) fluorescence consistent with significant scheelite mineralization.
  • The UAV magnetic survey has been completed and is currently being processed, with preliminary results expected imminently.
  • Soil sampling was completed across the Rowland Main zone, with reconnaissance soil lines extended across the Northern zones (A and B).
  • Rock samples and the initial round of soil samples have been rush submitted to the laboratory; assay results are expected over the coming weeks.

Blake Morgan, the chief executive officer and president of Western Star, stated: "Rowland has come out of phase 1 looking considerably more prospective than the historical record suggested. We expected a single past-producing zone; the field crew came back with multiple zones of extensive historical development, including a previously undocumented central area with processing infrastructure, shafts and 600 to 700 metres of trenching. We adjusted the program in real time to focus on what was actually on the ground and have rush submitted the first round of rock and soil samples so we can get assays back as quickly as possible. The team can now move on to the White Star property, where we hope to repeat the success we have had at Rowland."

Phase 1 field program summary

The phase 1 field program at the Rowland tungsten property was designed to deliver an integrated package of geophysical, geochemical and field mapping data to support drill targeting and the drill-permitting process.

This phase has confirmed multiple zones of extensive historical tungsten-bearing workings across the property. All zones are hosted within the same contact metamorphic tungsten skarn setting as the originally targeted Rowland workings, and all display significantly more historical development than was recorded in publicly available historical records.

Northern zones

The Northern zone A is the area that prompted the company's prior expansion of the Rowland claim package, and the phase 1 field results validate that decision. Desktop work identified the area as historically mapped as a single adit. Field crews confirmed the location of the adit, which is old and partially backfilled/demobilized. However, the surrounding waste dumps and surface piles are substantially larger and more extensive than the historical record indicates, indicating that a meaningful volume of historical material was mined and processed from this area.

The Northern zone B is the most significant historical development confirmed during phase 1 and was not documented in publicly available historical production records. The zone was first identified as a target during the company's premobilization lidar review, which flagged surface features consistent with historical workings, including several overgrown depressions that were suspected of being decommissioned vertical shafts. Fieldwork has now confirmed the suspected shafts, with three to four observed in the field.

Field crews also documented dilapidated wooden infrastructure consistent with a historical ore chute, indicating that this area was a historical processing site for the broader Rowland operation. In addition, a series of northeast-southwest-oriented trenches has been confirmed across the zone, testing approximately 600 to 700 metres of strike length.

Rowland Main zone

The Rowland zone is the original target area on the property and the historical production area for which the Rowland property was acquired. Phase 1 fieldwork confirmed multiple additional workings, trenches and surface disturbances up and down the slope around the previously known features, materially increasing the inventory of confirmed historical workings within area.

Material from the Rowland zone displayed extensive UV fluorescence consistent with scheelite mineralization, with tungsten content further confirmed by portable X-ray fluorescence (pXRF) screening.

UAV magnetic survey

The phase 1 UAV magnetic survey at the Rowland tungsten property represents the first modern high-resolution geophysical data set acquired across the property.

The data are currently being reviewed, processed and interpreted, with delivery of preliminary results expected shortly.

Rush assays, phase 2 and drill targeting

With phase 1 fieldwork complete, the company's near-term priorities are to receive and integrate the phase 1 assay results, finalize the phase 2 program, and advance the project toward drill targeting and drill permitting. Rock samples and the initial round of phase 1 soil samples have been rush submitted to the laboratory, and the company expects to receive the first tranche of assay results over the coming weeks.

The company will provide further updates as phase 1 assay results, geophysical interpretation products and the phase 2 program plan become available.
