The search for the wreckage of the Iranian Aseman aircraft remains "ongoing", IRNA reported.
A Red Crescent official said there was "no reliable news" that the crashed aircraft bound to Yasuj city from Tehran had been located.
Bad weather had thwarted a recovery mission on Sunday when a rescue helicopter was forced to turn back.
It was not immediately clear if search and rescue teams were able to reach the crash site on Monday.
The flight crashed 50 minutes after taking off from Kohangan, 120 km from Semirom town, authorities said.
All required facilities, including six aircraft, several helicopters, 40 relief aid workers of the Islamic Republic of Iran Red Crescent Society and climbers from the Ministry of Sports and Youth are engaged in rescue and relief operations, a government official said.
He said that 11 operation headquarters were formed for the rescue and relief, search, meteorological, conversation checking and scrutiny of the causes of the incident.(ANI)
