Assay's point to sedimentary hosted uranium targets
Highlights:
Uranium confirmed in assays: laboratory results from historic core hole C051 (within recently granted South Australian EL7079, part of AR3’s Overland Uranium Project) confirm the presence of uranium mineralisation:
0.44m @ 159ppm U3O8 from 56.6m within limestone
0.70m @153ppm U3O8 from 57.3m within limestone
0.90m @ 201ppm U3O8 from 60.3m within lignite
Extensive new target zones identified: The target zones, defined by numerous historic drillholes with anomalous gamma, has revealed two large uranium target zones with sedimentary layers above and adjacent to a widespread brown coal deposit.
Strong geological indicators:
Numerous historic drillholes show gamma anomalies suggesting widespread uranium potential.
Untested ground remains to the west near the regional Palmer Fault and to the northeast adjacent granitic basement rocks – both highly prospective structural settings within the new EL area.
Contact with intrusive basement rocks provides potential uranium source: Weathered and in some places outcropping granites within the Sedan area has produced a ‘wash’ of permeable sediments providing an accessible potential source of uranium for groundwaters moving through the area and into the adjacent highly reduced sediments.
Next Steps: Data integration and geophysical review to inform a drilling program for the new target areas that will be designed to confirm and expand mineralisation models “Anomalous Gamma” has been defined by historical downhole gamma surveys where the gamma response was 2x background or >100cps.
