Situated in the rocky terrain of Chimakurthy, Andhra Pradesh in the South of India, Hamsa Minerals (originally Nutrine Granites) started mining Black Galaxy granite with a workforce of 30 employees. Today the company is home to around 300 employees and houses its own processing plant, with annual export output reaching approx. 6500 Cbm. 

​

The primary material mined is Black Galaxy. Black Galaxy is a widely known form of granite with highly restricted geographic availability and a range of applications. Black Galaxy granite is only available in Chimakurthy, AP and its surrounding regions, and is nowhere else to be found in the world.
