Full Summary

Brightstar Resources Limited (ASX: BTR) has announced assay results from diamond core and reverse circulation drilling programs at the Two Mile Hill-Shillington deposit, part of the 2.9Moz @ 1.3g/t Au Sandstone Gold Project. Deep extensional drilling has intersected a much wider tonalite than previously interpreted, with the unit now interpreted to be >180m thick horizontally, a material increase relative to the previous interpretation. The new deep drillhole, TMHRCD26020, extended further into tonalite than anticipated compared to the existing interpretation, ending in mineralised tonalite at 657.3m. This result has tripled the interpreted thickness of the intrusion to >180m, with further drilling now planned to fully delineate the host unit. Significant intercepts from the high-grade intervals include 305.4m @ 1.82g/t Au from 351.9m, including 17.5m @ 9.68g/t Au from 351.9m, 13.4m @ 8.59g/t Au from 531m, and 34.6m @ 4.11g/t Au from 586.7m. Visible gold was observed throughout the mineralised tonalite in TMHRCD26020.

Outlook

The company plans to continue drilling to fully delineate the host unit and upgrade the Mineral Resource Estimate.
