The Stawell Gold model success The Stawell Gold Mine has produced 5.3 Moz Au: the 4th-largest goldfield in Victoria1. High-resolution geophysics detects “covered” or deeper basalt targets. Unmineralised sediments (“cover”) mask gold prospective geology. Gold mineralisation basalt core. in structures

Darlington Target – Mariners-type or Mariners-repeat? (2025) Darlington includes brecciated quartz-sulphide vein3 and basalts at depth (NSD053(1) and NSD057(2)) – a mineralised ‘splay’ off the basalt at depth “Mariners Type”. NSD057: 2.3m at 29.2 g/t Au from 108.2m Includes 0.8m at 82.3 g/t Au from
