Alien Metals (AIM:UFO) told investors that GreenTech Metals, its joint venture partner at the Munni Munni PGE-Cu-Ni project, has published findings from an independent geochemical review of the site.
Alien Metals, an AIM-listed minerals exploration and development company, holds a 30% stake in the Munni Munni joint venture, with GreenTech Metals holding the remaining 70%.
The review, conducted by consultant geochemist Dr Scott Halley, identified discrete high-priority exploration targets around the base of the Munni Munni intrusive complex.
Soil geochemistry shows copper anomalism over the base of the ultramafic sequence, pointing to potential for basal contact-associated copper-nickel-PGE (platinum group element) mineralisation, a target zone not previously the focus of exploration at the project.
A separate copper anomaly spanning around 5km by 2km, linked to elevated vanadium and titanium in the upper sequence, suggests magnetite-rich zones carrying disseminated copper sulphides.
Dr Halley said the ultramafic rocks in the lower intrusion "have an unusually low copper content strongly suggesting that these magmas at some point contained immiscible droplets of sulphide melt", a process he considers critical to forming high-grade copper sulphide lodes.
GreenTech plans a co-funded fixed-loop electromagnetic geophysical survey this month over the target areas, designed to detect deep conductive sulphide bodies ahead of finalising basal contact drill targets at Munni Munni.
