Dr. T. S. Sunil Kumar obtained M. Sc. Degree in Geology from University of Kerala in 1985 and Ph.D. from Osmania University in 2001 for his pioneering work on uranium-copper-precious metal metallogeny along the Singhbhum Shear Zone. He started his professional career at the Mineral Processing Division of Bhabha Atomic Research Centre (BARC), where he has made remarkable contributions as Ore Mineralogist and Process Mineralogist on major Indian uranium Ores, tin, tungsten, copper, beach sand minerals and rare metals. Subsequently he joined Atomic Minerals Directorate for Exploration and Research (AMD) in 2001 and has served the department in various capacities in survey and exploration, mineralogical and geochemical studies, applied research and has effectively guided survey and exploration for uranium, rare-earth elements and rare-metals and beach sand mineral deposits. He superannuated from AMD as Additional Director (Research and Development) in 2023.
He is a professional process mineralogist with experience on (i) uranium ores at viz. Jaduguda, Bhatin and Narwapahar, Singhbhum Shear Zone; Domiasiat, Meghalaya; Gogi, Karnataka, (ii) Beach sand deposits of Ratnagiri, Maharashtra, Kalingapatnam and Bhavanapadu, Andhra Pradesh, Kudiramozhi, Tamil Nadu (iii) Tungsten deposits of Khobna, Maharashtra; Degana, Rajasthan and Burugubanda-Tapaskonda, Andhra Pradesh; (iv) gold-PGE-silver mineralisation at Jaduguda, Jharkhand and Khetri, Rajasthan; (v) Tin ore from Tosham, Haryana, (v) Cu ores of Malanjkhand, Madhya Pradesh and Kalyadi, Karnataka. He has contributed as an exploration geologist of AMD in the fields of mineral exploration, deposit modeling and characterization. He has worked in parts of Cuddapah basin, Andhra Pradesh, and North Delhi Fold Belt, Haryana and Rajasthan. He has ably guided and managed exploration and research for rare-metal and rare earth elements, including Ambadongar carbonatite complex, Siwana Ring Complex, Rajasthan and heavy mineral deposits along the west and east coast of India. He efficiently managed the analytical activities in state-of-the-art laboratories for on-time generation of quality data and research programmes on genetic studies of deposits and ore-modelling.
Dr. Sunil Kumar, with 85 publications, is the recipient of (i) Group Achievement Award (2021) of DAE as Group Leader for the exploration activities on REE deposit at Ambadongar, Gujarat; (ii) Dr. G. R. Udas–K.K. Dwivedy Medal (2013) of Indian Society of Applied Geochemists and (iii) Indian Institute of Mineral Engineers (IIME) Award for Best Paper on ore characterization (2000). Dr. Sunil Kumar is actively engaged in guiding and overseeing exploration and associated R&D on base-metals and critical mineral resources in diverse geological domains and development of state-of-the-art analytical facilities for ore characterization and applied studies in GMRICS from 2024.
