Track and drill pad earthworks are expected to start this week, with drilling scheduled to commence in early-June 2026.
Diorama is a DeGrussa style copper-gold target located immediately north of Great Western’s Juggernaut copper-gold targets.
It was initially defined as a lag copper anomaly, with field mapping defining gossanous quartz from the limited surface outcrop at this location, which was mapped in some areas with extents greater than 100m.
MD, Shane Pike, said shallow cover has been defined throughout, with no drilling undertaken at the location to date.
Great Western interprets Diorama to represent a compelling volcanic hosted massive Sulphide (VHMS) style mineralisation target, similar to the nearby DeGrussa copper-gold deposit.
The 3,000m air core drilling program will test below the shallow cover at Diorama, with the aim to advance the target for future targeted drilling of discrete and obscured zones for copper-gold enrichment.
The company is also planning to advance exploration on several regional copper-gold targets within the Yerrida Basin, concurrent with the drilling campaigns, with the aim of progressing these targets to drill- ready status.
On completion of the Diorama air core drilling campaign, RC drilling of six individual copper-gold targets will be undertaken at the nearby Juggernaut project.
The six targets of Juggernaut, Seymour, Falconer, Howard, Palmer, Smith and Archer were defined by each individual target’s stratigraphic, structural, and geochemical attributes. A large and zoned copper-lead-zinc anomaly covers all targets.
The next stage of drilling is anticipated to commence in July 2026.
It will then move to the Baroo copper-gold target, a previously unmapped quartz vein that has returned elevated copper results.
GTE is steady at 1.4c. Mkt cap $10.88M.
