May 26, 2011

TORONTO, May 26, 2011 /CNW/ - Gran Colombia Gold Corp. (TSX: GCM) and Medoro Resources Ltd. (TSX: MRS) (together, the "Companies") are pleased to jointly announce that Institutional Shareholder Services Inc. ("ISS") is recommending that its clients vote in favour of the combination of the Companies (the "Arrangement Resolution"), to be considered at the respective securityholder meetings of each company scheduled for June 7, 2011.

In recommending that securityholders vote FOR the Arrangement Resolution, ISS stated in its report*:

"The transaction is structured as a merger of equals. The companies believe the combined company's growth prospects are greater than either could achieve on their own. The companies expect to realize cost savings from a single human resources and community relations program as well as production synergies and economies of scale from more efficient use of facilities. The combined company will have exposure to two large production and development projects and is expected to be well positioned to take advantage of consolidation opportunities. The combined management team is said to be well suited to dealing with potential political, social and economic issues in Colombia."

"We are pleased ISS shares our view that Gran Colombia and Medoro securityholders should vote FOR the Arrangement Resolution," said Serafino Iacono, Executive Co-Chair of Gran Colombia and Interim President and Chief Executive Officer of Medoro. "At a time of record high gold prices, this merger enables the combined company to become the leading Colombian-based gold production, development and exploration company. The amalgamated companies will benefit from the current production and expansion potential at the Gran Colombia gold mine and the large-scale Marmato gold development project, both located in the vicinity of Medellin, Colombia."

A joint management information circular, dated May 6, 2011, has been mailed to securityholders and filed on SEDAR (  The joint circular contains, among other items, details regarding the Arrangement Resolution, the terms of the acquisition, the business of Gran Colombia and Medoro and certain historical and pro forma financial information relating to Gran Colombia and Medoro.
