John Michael Parianos graduated with a research MSc in Geology from University of Queensland in 1993 specialising in volcanic and igneous sequences in coastal central Queensland. He went on to spend 7 years exploring and researching nickel-cobalt laterites in the south-west Pacific region for the company QNI, before moving to Africa for 8 years. There he worked in a variety of different metal deposit types (Ag-Pb-Zn, Iron ore, Cu, Ni-Cu, Al, Coal, Diamonds, Au) in a variety of roles (mineral resource estimation, exploration management, investment analysis and management).
Between 2008 and 2012 John worked as Geology Manager for BHPBilliton for the corporate development section of their Australasia based stainless steel materials division. This role included business development, due diligence, mineral resource reporting, corporate knowledge management and client liaison with group exploration. It involved programmes in almost every continent.
Since early 2012 John has worked as Nautilus Minerals, now managing both global exploration of deep seafloor massive sulfides and development of Nautilus’ TOML polymetallic nodule project in the Clarion Clipperton Zone. The exploration management role includes generation of new concepts, hands-on management of exploration programmes, exploration technology development and commercial-permitting relationships and management. The polymetallic nodule project adds the additional dimensions of environmental programmes, mineral resource estimation, mine engineering technology development, process metallurgy-metals market, and economic evaluation.
Nautilus Minerals was granted the first mining lease for deep seafloor massive sulfide at the prospect known as Solwara 1, in the territorial waters of Papua New Guinea, where it is aiming to produce copper, gold and silver. The Company has also been granted its environmental permit for this site. The company is the first to publish Canadian NI 43-101 Mineral Resource estimates for both seafloor massive sulfides and polymetallic nodules.
