PMS exploration
Ministry of Earth Sciences (MoES) has signed a 15-year contract with the International Seabed Authority (ISA) for exploration of Poly-Metallic Sulphides (PMS) in Indian Ocean.
The contract was signed on September 26, 2016, to explore 10,000 sq. km. area along Central Indian Ridge (CIR) and Southwest Indian Ridge (SWIR) region of the Indian Ocean.
PMS, containing iron, copper, zinc, silver, gold, platinum in variable constitutions, are precipitates of hot fluids from upwelling hot magma from deep interior of the oceanic crust, discharged through mineralized chimneys. PMS in the Ocean Ridges have attracted worldwide attention for their long term commercial as well as strategic values. fii-news.com
