In a statement issued here, Ajay alleged that the BJP government was "sleeping peacefully after handing over the state's mineral resources to the mining mafia".
Congress had drawn the attention of the state government to illegal mining activities, but nothing has been done to stop it, he said.
If the Chief Minister is really honest, he should recommend a CBI probe into illegal mining, Singh said.
By doing so, Chouhan will get a chance to prove his claim that those involved in illegal mining would not be spared even if they belonged to the BJP.
