Vancouver, B.C. - May 21st, 2015 - Magellan Minerals Ltd. (TSX-V: MNM) ("Magellan") is pleased to announce that further to its news release dated April 8, 2015, it has filed with the British Columbia, Alberta, Ontario and Nova Scotia Securities Commissions, a NI 43-101 Technical Report dated May 13, 2015 (the "Report") in connection with the updated resource estimate for the Coringa project, Brazil. The Report was prepared by Mr. Walter Dzick, P.Geo., a registered Professional Geologist with APEGBC and Principal Geologist at Snowden Mining Industry Consultants ("Snowden"), and forms part of the ongoing feasibility study. The Report can be found on SEDAR at www.sedar.com and on Magellan's website at www.magellanminerals.com.

Measured and indicated resources at Coringa amount to 553,000 ounces of gold representing 2.18Mt @ 7.88 g/t gold at a 2.5g/t cut-off grade. Inferred resources of 360,000 ounces of gold have been calculated representing 2.06Mt @ 5.43 g/t gold at a 2.5 g/t gold cut-off grade.

Due to internal corporate issues, Snowden who is responsible for the resources, reserves and underground geotechnical components of the feasibility study, had to move the mining work component of the study from their Vancouver office to their Perth offices. This move added an unanticipated level of complexity due to time zone differences that in conjunction with certain mining method optimization requested by Magellan, has resulted in the anticipated completion date of the study being delayed until early June 2015.

Despite this delay, the remaining components of the study are largely complete. Ausenco Engineering Canada Inc., which is responsible for the overall study compilation, has completed the detailed process plant design as well as the site infrastructure, access road and electrical power supply aspects. Kovit Engineering Limited has completed the design and costing of the tailings and backfill aspects of the project and Global Resource Engineering has completed the hydrogeology and the site water balance studies on the project. Terra Meio Ambiente has completed the environmental and permitting aspects of the study. Deswik Mining Consultants have completed the mining redesign and scheduling and in conjunction with Snowden will finalize the mine plan and reserves for study completion during early June.

In addition, Mario Szotlender, a founding director of the Company has announced his resignation from the Board of Directors. Mr. Szotlender sits on a number of other boards of public companies including both Fortuna Silver Mines Inc. and Endeavour Silver Corp. and has been advised by a proxy advisory service to institutional shareholders that they will not recommend his re-election as he sits on more than six boards. Hence, his decision to resign from the board of Magellan. He will remain as a corporate advisor to the Company. Alan Carter, President & CEO commented "it is very unfortunate that Mario has had to resign as a director from Magellan due to external pressures forced upon him, but I am grateful for the many years of invaluable counsel provided to Magellan and am happy that he will remain as a corporate advisor to the Company".
