About the report

The physiography of the Jabiluka minesite embodies a significant paradox. This is that a world-class uranium (U) orebody is overlain by streams that contain the element at concentrations of only a few nanograms per litre, which is near the practical detection limit. Indeed, uranium concentrations in Swift Creek and its tributaries are in the bottom percentile of freshwater worldwide. The baseline and near-baseline data contained here provide a data set which will allow very small deviations from unaffected concentrations to be easily detected. This is an ideal position from a regulatory and monitoring viewpoint.
