VANCOUVER, Dec. 31, 2012 /PRNewswire/ - Guyana Frontier Mining Corp. ("Guyana Frontier", TSXV: GYG) announces that its proposed acquisition of the Falcao Gold Project (the "Acquisition") from a subsidiary of Horizonte Minerals Plc. ("Horizonte", AIM and TSX: HZM), originally announced in Guyana Frontier's news release dated November 6, 2012, has been terminated.

Under the terms of the acquisition agreement (the "Acquisition Agreement") between Guyana Frontier and Horizonte's subsidiary, it was a condition precedent to the completion of the Acquisition that Guyana Frontier's shareholders approve a share consolidation on a ratio of between one for two and one for ten, with the final ratio of the share consolidation to be agreed upon by Guyana Frontier and Horizonte's subsidiary (the "Share Consolidation Approval Requirement"). At the annual and special meeting of Guyana Frontier's shareholders held on December 21, 2012, Guyana Frontier's management sought shareholder approval of a resolution in accordance with the Share Consolidation Approval Requirement, approving a share consolidation on a range of between one for two and one for ten, with the final ratio of the share consolidation to be determined by Guyana Frontier's board of directors. The foregoing resolution did not receive the required special majority approval, and Guyana Frontier's shareholders instead approved a share consolidation on a ratio of one for four, which did not fulfill the Share Consolidation Approval Requirement. On December 28, 2012, Horizonte provided notice to Guyana Frontier that it was terminating the Acquisition on the basis that Guyana Frontier would be unable to meet the Share Consolidation Approval Requirement prior to the outside closing date for the Acquisition under the terms of the Acquisition Agreement.
