Short summary
This study investigated previously underexplored deep-water movement in the Bushveld Complex. Analysis of water and rock data from a deep exploration well revealed distinct changes in water chemistry at 450 m below ground level, associated with a severely fractured rock layer and a deep rock conduit. These features indicate potential deep, saline, gas-rich water pathways containing high dissolved salts and specific metals, providing insight into deep fluid migration in fractured hard rocks.
