Summary
Brightstar Resources Limited has announced a significant finding of visible gold within the Two Mile Hill-Shillington deposit, part of the Sandstone project. Recent drilling uncovered a new geological zone, the 'Shirvington Zone,' characterized by a much thicker and wider mineralised tonalite than previously understood. This finding indicates that the tonalite is over 300 meters wide at a depth of approximately 700 meters. The presence of visible gold, primarily within quartz veins and occasionally within the tonalite itself, has been confirmed throughout the drilling program, which covers around 3,400 meters. These developments are set to considerably influence future Mineral Resource updates as the company awaits detailed assays and further exploration results.
Key Points
  • Brightstar Resources Limited announced significant visible gold in the Two Mile Hill-Shillington deposit.
  • The drilling program revealed more visible gold and a significantly thicker mineralised tonalite, termed the 'Shirvington Zone'.
  • New geological models suggest the tonalite is over 300m wide at around 700m depth.
  • The updated interpretation shows a materially wider tonalite, which will affect future Mineral Resource estimates.
  • Gold mineralisation is associated with quartz veins and pyrite within the tonalite.
  • The drilling program consists of approximately 3,400m of diamond drilling.
  • Visible gold is frequently observed within quartz veins and less commonly within the tonalite itself.
  • Future assays and additional drilling cores are anticipated to provide further insights.
