Although it is understood that the heavy minerals that come under the alleged illegal heavy mineral mining scam are expensive and rare. It still does not make sense that the scam will amount to so much money. S Vaikundarajan of VV Minerals India has rubbished this claim and said even financial projections cannot scope out such a large amount of money to be involved.
