Vancouver, BC, Canada, March 28th, 2016. Columbus Gold Corp. (CGT: TSX, CBGDF: OTCQX) ('Columbus') has provided notice to Eastmain Resources Inc. (TSX: ER) ('Eastmain') of its intention to nominate five new directors to Eastmain's Board at Eastmain's annual and special meeting of shareholders to be held on April 25, 2016 (the 'Meeting').

Significant Percentage of Eastmain Shareholders Support Board Change

It has come to the attention of Columbus, which holds 2,675,000 common shares of Eastmain, that its concerns are shared by several other shareholders holding a significant percentage of the shares of Eastmain (collectively, the 'Concerned Shareholders').

Lack of Progress under Current Eastmain Management

The Concerned Shareholders are dissatisfied that, after more than 21 years under the leadership of the same President and Chief Executive Officer, Eastmain has not made sufficient progress in advancing its projects. The lack of progress is disappointing given the quality of Eastmain's assets. Management of Eastmain continue to enjoy the benefits of their entrenched position while shareholders have not realized the true potential of their investment.

Columbus believes that the value of Eastmain can be unlocked, and in order to achieve this goal it will be necessary to change the Board of Eastmain to one with strong capital markets and transactional experience, and proven leadership.

Brighter Direction for All Shareholders under Experienced New Board

Columbus proposes to reconstitute the Board of Eastmain with the following five highly qualified nominees:

• two Columbus directors, Robert Giustra and Peter Gianulis;
• two directors who are independent of Columbus, Shawn Wallace and Geoff Stanley; and
• Michel Jébrak, an independent advisor to Columbus on community and social responsibility and on Québec and French government relations.

On successful completion of the reconstitution of the Board, Laurence Curtis, a highly respected and qualified existing and recent Eastmain Board appointee, will be invited to join the Board; should he wish to remain a director.

Eastmain's technical team will be evaluated and reinvigorated with the task of accelerating exploration at the Clearwater Project. With this goal in mind, the Eau Claire gold deposit will be put on a more rapid path to completion of a definitive feasibility study.

The reconstituted Board will consider strategic alternatives, and evaluate all proposals (including by parties related to the nominees, if any) in a robust, credible and transparent process, to maximize the value of Eastmain for all its shareholders.

The five nominees proposed by Columbus have an exceptional track record of success in the junior mining sector and a wealth of experience in every aspect of the industry. They include:

Robert Giustra -- Mr. Giustra is the Chairman and CEO of Columbus Gold Corp., which in 2015 was selected from a peer group of some 1,200 mining companies as a TSX Venture 50 company -- a ranking of the top 10 companies in each of the five major industry sectors that make up the TSX Venture Exchange.
