Nautilus Minerals Recommences Exploration Programs

TORONTO, ONTARIO--(Marketwired - April 7, 2015) - Nautilus Minerals Inc. (TSX:NUS)(OTCQX:NUSMF) (the "Company" or "Nautilus") announces it has signed a contract with Gardline CGG Pte Ltd ("Gardline CGG") to provide exploration services for Nautilus' 2015 program in the Solomon Islands. The vessel MV Duke will be used to generate targets to expand Nautilus' Seafloor Massive Sulphide ("SMS") prospect inventory within its 100% owned Solomon Islands exploration licenses.

Mike Johnston, Nautilus' CEO, commented, "we are excited to be back on the water this year, focused on adding to our high grade SMS prospect inventory by applying the successful high tech exploration techniques we have been refining since 2006. This is the second time we have been supported by Gardline in our exploration efforts and we look forward to continuing our relationship with them."

The contract with Gardline CGG is for 43 days of services, mobilising from Brisbane, Australia on or about April 25, 2015. The program will define SMS targets using efficient multibeam echo sounder and plume hunting techniques. Plume hunting is a regional geochemical technique involving the discovery of metal rich plumes of material that are ejected into the water column from prospective areas, by natural geological processes. The primary objective of this program is to discover further mineralised systems to support the Company's business model. Amongst its many anticipated advantages, seafloor resource production will allow the aggregation of resources from multiple mineralised systems without the need for significant additional capital.

The MV Duke vessel, which will be used for this program is a 67 metre long, 2031 gross tonne, Survey Vessel, originally built in 1983, and then extensively refitted in 1998 by A/S Vaagen Vert, Norway. The vessel is equipped with a hull mounted Kongsberg EM302 multibeam system, a state of the art seafloor mapping system that provides some of the highest quality seafloor mapping data available.
