 Strong continuity of high-grade gold in Sandstone drilling
Key Points
  • Final assay results confirm continuity of high-grade mineralisation within the optimised pit shell and extensions to mineralisation at depth
  • RC drilling program now underway at Vanguard Camp, targeting along strike / down plunge extensions and infilling key areas of the high-grade Vanguard North deposit
  • Consolidated Sandstone Gold Project hosts 1.5Moz @ 1.5 g/t Au from surface, with an aggressive 55,000m RC drilling program on track to rapidly upgrade and expand the existing Mineral Resource across multiple deposits
Full Summary

Brightstar Resources Ltd has received the final results from a ~3,700m Reverse Circulation (RC) drilling program, targeting depth extensions and infill resource drilling at the Lord Nelson deposit, located within the 1.5Moz @ 1.5g/t Au Sandstone Hub. The drilling program has confirmed the continuity of high-grade mineralisation within the current mineral resource defined by the A$2,500/oz Au optimised pit shell. Extensional drilling in the southern portion of the mineral resource also intersected significant gold mineralisation, which is expected to be included in a future update to the Mineral Resource Estimate. The Lord Nelson deposit is hosted at the northern tip of a large granodiorite intrusion, with mineralisation typically characterized by a visible zone of pyrite + silica + biotite +/- quartz veining that follows the ultramafic footwall contact. Previous mining by Troy Resources NL between 2007 and 2010 at Lord Nelson produced 207koz @ 4.6 g/t Au via open pit methods. The consolidated Sandstone Gold Project currently hosts a Mineral Resource Estimate of 1.5Moz @ 1.5 g/t Au, with an aggressive 55,000m RC drilling program underway to rapidly upgrade and expand the existing Mineral Resource across multiple deposits. The RC rig has now moved to the Vanguard Camp, targeting along strike / down plunge extensions and infilling key areas of the high-grade Vanguard North deposit.

Outlook

Brightstar is continuing an aggressive 55,000m RC drilling program across the Sandstone Gold Project, with the aim of rapidly upgrading and expanding the existing 1.5Moz @ 1.5 g/t Au Mineral Resource. An additional drilling rig is also scheduled to arrive at the Laverton Hub in March, followed by a diamond rig in April, with the drilling to target extensions and infilling areas within the Cork Tree Well deposit as well as depth and strike extensions to the Fish deposit to support potential for mine life extensions.
