Guyana Frontier Provides Update on Sardine Hill Project

VANCOUVER, May 5 /PRNewswire/ - Guyana Frontier Mining Corp. ("Guyana Frontier") wishes to inform its shareholders of a title dispute affecting a small portion of the Sardine Hill property ("Sardine Hill") in Guyana, South America. Mariwa Mining Company Inc. ("Mariwa"), a private Guyanese corporation, is the holder of a prospecting licence comprising the Sardine Hill property. Guyana Frontier has an option to acquire all of the issued and outstanding shares of Mariwa by making cash and share payments over a period of five years.

Guyana Frontier subsequently granted an option to Mulgravian Ventures Corporation ("Mulgravian"), a private Canadian corporation, whereby Mulgravian can earn a 51% interest in the shares of Mariwa by completing certain exploration expenditures and completing a private placement with Guyana Frontier.

On March 23, 2011, Guyana Frontier was named as a co-respondent in a lawsuit filed by Ignatius Timmerman ("Timmerman") against the Guyana Geology and Mines Commission (the "GGMC"), Odinga Lumumba - one of the principals of Mariwa - and Guyana Frontier. Timmerman claims to own the rights to five mining claims (the "Alleged Claims") totalling approximately 138 acres (55.8 ha.) within the area of the Sardine Hill prospecting licence. The total area of the Sardine Hill prospecting licence is 10,427 acres (4,220 ha.), and the Alleged Claims overlap a portion of the known mineralized area of the Sardine Hill property.  Both the GGMC and Mariwa contest the legality of the Timmerman mining claims. In August 2010, the GGMC determined the Timmerman mining claims to be invalid and delivered a cease work order to Timmerman.  On March 17, 2011 the GGMC carried out an eviction of Timmerman's mining equipment and personnel from Sardine Hill.

Timmerman subsequently filed a lawsuit against the GGMC, Mariwa and Guyana Frontier on March 23, 2011 seeking an order:

• confirming his rights to the Alleged Claims;
• for the return of the mining equipment seized by the GGMC on March 17, 2011;
• to deny access to Guyana Frontier to the area of the Alleged Claims; and
• for damages "in excess" of US$5,000 (Guyana$1.0 million) against the GGMC, and "in excess" of US$5,000 (Guyana$1.0 million) jointly from Odinga Lumumba and Guyana Frontier - the amount "in excess" is unspecified in both cases.

Timmerman was granted an interlocutory injunction denying Guyana Frontier access to the area of the Alleged Claims.  The interlocutory injunction was granted on an ex parte basis, and is in effect until the next hearing date.  On April 13, 2011, a court hearing was held in Guyana and the matter was adjourned until May 11, 2011.

In April 2011, Guyana Frontier completed a diamond drilling program at Sardine Hill for a total of 3,076 metres in 18 holes, which achieved the planned meterage announced in a news release on December 16, 2010. Complete analytical results will be released after their receipt, compilation and interpretation.

The technical work disclosed in this document was planned and supervised by David Bending, M.Sc., P.Geo., President and CEO of Guyana Frontier, who is a Qualified Person as defined in National Instrument 43-101, and is responsible for all technical information contained in this news release.
