 Impressive Results in the Butterfly Area of Mainfield
Key Points
  • Drilling of the Butterfly zone from a dedicated exploration decline has returned high-grade results including 1.5 m @ 81.23 g/t Au
  • Mineralisation lies only 70 metres east of the recently developed Butterfly decline, facilitating easy access for potential mining
  • Known mineralisation at Butterfly extends a further 1.5 kilometres to the south and remains open at depth
Full Summary

Pantoro Gold Limited (ASX:PNR) is pleased to provide further results from its ongoing underground drilling program from the Bullen Decline in the Mainfield at Norseman. Drilling from the Bullen Decline is ongoing across multiple zones, including the Butterfly area of the Mararoa Reef, which has historically produced an estimated 1.4 million ounces of gold. The drilling of the Butterfly zone is being undertaken from a dedicated exploration decline developed during the past year. High-grade results have been consistently returned to date, including 1.5 m @ 81.23 g/t Au inc. 0.5 m @ 223.65 g/t Au, 1.7 m @ 34.35 g/t Au inc. 0.36 m @ 143.02 g/t Au, and 1.1 m @ 26.88 g/t Au inc. 0.72 m @ 40.35 g/t Au. The mineralisation lies only 70 metres east of the recently developed Butterfly decline, facilitating easy access for potential mining. Known mineralisation at Butterfly extends a further 1.5 kilometres to the south and remains open at depth. Pantoro expects the Butterfly program to be significantly extended in order to provide coverage over an area sufficient to commence mining as the second independent mine area within the Mainfield development.

Outlook

Pantoro Gold expects to drill approximately 250,000 metres of combined RC, diamond and air core during FY2026 as part of its growth strategy to expand its underground mining operations and scale production at Norseman.
