TORONTO, May 30, 2011 /CNW/ - Gran Colombia Gold Corp. (TSX: GCM) and Medoro Resources Ltd. (TSX: MRS) (together, the "Companies") have re-affirmed their strong commitment to completing a friendly combination of the Companies, and have rejected the recommendations contained in two separate reports from Glass, Lewis & Co., LLC ("Glass Lewis"), a professional services firm that provides proxy research and voting recommendations to institutional investors. The Glass Lewis reports are in contrast to the positive recommendation of Institutional Shareholder Services Inc. ("ISS").

The Companies believe the approach used by Glass Lewis to analyze the combination is fundamentally flawed in several respects and does not adequately assess the rationale of the transaction. In its analysis, Glass Lewis failed to address several key factors, including: (1) the structure of the transaction; (2) the rationale and process of the transaction; and (3) the Colombia-specific considerations. Furthermore, the basis for its recommendations has been founded on erroneous facts.

It is inconceivable that the Glass Lewis analyst who authored the two separate reports came to conclusions totally at odds to each other. The Medoro shareholders are being told that they are being offered too little consideration, while Gran Colombia shareholders are being told that they are offering too much consideration. This analysis is at best counter intuitive and at worst fundamentally flawed. It defies logic to think that the same analyst could publish two separate recommendations in respect of the same transaction with opposite conclusions in terms of the adequacy of the consideration.

In addition, the original Glass Lewis report to Medoro shareholders did not take into consideration or assign value to the warrant component of the offer price. Failing to include the value of the warrants brings the conclusion of the original report's analysis into serious doubt. The joint circular clearly states that the consideration warrants will be issued under the existing Gran Colombia indenture and that such consideration warrants will be the same warrants currently traded on the Toronto Stock Exchange (under the ticker symbol "GCM.WT"). The fact that this was not properly addressed suggests that Glass Lewis did not fully review the contents of the joint circular and/or did not understand the basic terms of the transaction. Glass Lewis has since revised their reports to take into consideration and assign value to the warrant component of the offer price - however, this omission nonetheless remains prima facie evidence that the precise details of the transaction have not been properly reviewed or considered.

The following sets out in greater detail the Companies' position with respect to the transaction:

ISS, which is Glass Lewis' closest industry peer, recently released a recommendation that they support the transaction and an excerpt from their conclusion illustrates that, unlike Glass Lewis' analysis, ISS has completed a full review and understands the transaction. In its report, ISS stated: "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 (42% compound annual growth rate in production is expected from 2011 to 2016). 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."*

It is the view of the Companies that, in this case, Glass Lewis grossly overlooked several crucial factors needed to make an informed decision on this merger and that the merits of their recommendation must be questioned.

Given the deficiencies identified in the Glass Lewis reports, the Companies believe that shareholders should ignore these inconsistent reports and vote FOR the arrangement resolution. 

A joint management information circular, dated May 6, 2011, has been mailed to applicable securityholders and filed on SEDAR (www.sedar.com). 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.
