He advocated capital punishment on the culprits.
Mr Ogah made the remarks at a two-day public hearing organised by the Senate Committee on Solid Minerals, Mines, Steel Development and Metallurgy.
The public hearing was set up as an enquiry into the country’s $9 billion annual loss in mining and gold smuggling.
The minister also recommended harsher punishment for the perpetrators.
“For these crimes to be fought decisively, potent punitive measures like capital punishment need to be legally provided for,” he said.
He added that smuggling of gold and mining was tantamount to robbing the country of billions of dollars every year.
