The draft of granite policy 2009 by the Tamil Nadu state government aimed at enabling efficient exploitation of granite reserves in Tamil Nadu in a transparent manner, with due regard to the conservation of minerals, safety of labourers, mines and environmental protection.

The National Mineral Policy 2008 emphasizes that mining infrastructure requires a special thrust as the economic efficiency of excavation of minerals from pits mouth to user point is closely linked to the end use value of mineral and the viability of the Industries using the mineral. The greater part of Tamilnadu is occupied by hard crystalline rocks. The state is thus bestowed with vast resources of granite deposits. The black granites are confined to northern districts viz. Kancheepuram, Tiruvellore, Vellore, Dharmapuri, Krishnagiri, Salem, Erode, Perambalur, Villupuram, Tiruchy and Tiruvannamalai. The multi coloured granites are spread over southern districts and in
Salem, Krishnagiri and Dharmapuri Districts.
