Further Exploration
Four new prospect areas identified for further exploration
Calingiri
Target Commodities
- Ni-Cu-PGE hosted in mafic / ultra-mafic intrusive rocks
- BIF hosted gold
Project Geology#
Age: Archean 4 Ga – 2.5 Ga
Terrane: Youanmi Terrane
GSWA Lithology: Gabbro; metamorphosed granodiorite; mafic rocks; iron formation
# Source: Geological Survey of Western Australia, Youanmi Terrane (YYO) explanatory notes
Exploration Analysis
- Northern extension to NRL’s Bolgart project;
- Bounded by terrane-scale thrust / Paleo cratonic boundary;
- High amplitude discordant magnetic anomalies may indicate mafic-ultramafic intrusive rocks;
- Quartz sulphide BIF with Au potential.
