Hawks nabbed nine suspects for possessing precious metals

Officers found about 20kg of palladium, 11kg of osmium, and specialised machinery used to process unwrought gold.
Hawks spokesperson Warrant Officer Thatohatsi Mavimbela said the operation followed intelligence received on Friday, 4 September, about a foreign national allegedly trading in unwrought gold dust and nuggets sourced from illegal miners.
“Following intense surveillance, the team operationalised a search warrant at a targeted premises in Greenstone on Tuesday, 8 September 2026. Upon entering the property, officers detained two females and seven males,” Mavimbela said.

The Hawks arrested the nine suspects, aged between 20 and 56, after they failed to provide legitimate licences, permits, or company registration documents to handle or sell precious metals.
