Astro (ASX:ARO) strengthens IOCG credentials at Georgina
Astro Resources have upgraded the prospectivity of its 80%-owned Georgina IOCG Project in the Northern following solid copper-bearing minerals and minerals and anomalous pathfinder elements for IOCG mineralisation at the Project’s Banks and Leichhardt West prospects.
Diamond drilling assays confirm IOCG prospectivity highlighted by encouraging intersections at Leichhardt West, returning 0.22% Cu from 536.05-536.3m and 0.15% Cu from 600- 600.8m (at the end of the hole).
The Company views the findings as highly significant as they suggest the drilling may have intersected rocks peripheral to an IOCG system, possibly indicating a compelling similarity to Tennant Creek IOCG deposits.

“I am pleased with the positive early results that indicatedrilling may have hit the outer edge of a mineralised IOCG system within the Central Tenement,” Chairman Tony Leibowitz said.
“We’re now awaiting final results of our EM surveys, as well as assays from Leichhardt East, with this data to feed into a detailed review of the Central Tenement area to help plan next steps and prioritise drill targets.”
Final testwork data is expected to provide a complete view of the Central Tenement area will be conducted which will include a broader review of elevated magnetic and gravity responses (see Figures 5 and 6) interpreted to be prospective for IOCG-style mineralisation, supported by the rock types, alteration and geochemistry results received for drill holes completed to date.
