Two Kazakhs have been released from an Iranian prison after they were detained on April 5, Radio Free Europe/Radio Liberty reported on Monday.
The two Kazakh citizens had been arrested with another Kazakh national and two Russian citizens at the beginning of the month while they were working for the Zarkuh gold exploration company.
The third Kazakh citizen is still in detention, and the Kazakh embassy in the Iranian capital Tehran is working to secure his release.
The company is a joint venture between Kazakhstan and Iran.
According to the Russian foreign ministry, none of those arrested in Iran had any formal charges brought against them, nor was there a clear reason for their detainment.
Zarkuh was established in 2005, and also prospects copper, lead, zinc, and rare earth metals.
