Guyana Frontier Reports Drilling Program at Five Star Gold Project

VANCOUVER, Nov. 27, 2012 /PRNewswire/ - Guyana Frontier Mining Corp. ("Guyana Frontier") is pleased to announce that Mulgravian Ventures Corporation ("Mulgravian", a private Canadian exploration company) has begun a diamond drilling program on the Five Star Gold Project ("Five Star"), located in northwest Guyana, South America. The initial drilling program at Five Star is planned for a total of up to 10,000 metres over the next twelve months, with the final drilling meterage total dependent upon results.

Highlights of Five Star 2012 Exploration and 2013 Exploration Plans

• Prospecting and geological mapping, trenching, soil auger geochemical, and diamond drilling programs are underway;
• An airborne magnetic and radiometric survey is complete over all areas of Five Star;
• Construction of an airstrip and improvements to Five Star road access are planned; and
• 2013 program and budget presented by Mulgravian totals approximately US$6.7 million.

A joint venture was formed in April 2012 on Five Star with Mulgravian as operator holding a 51% interest and Guyana Frontier holding a 49% interest (see Guyana Frontier news releases dated April 17 and July 11, 2012). Guyana Frontier previously elected not to contribute to the 2012 Five Star program, and will be subject to standard dilution of its 49% interest in Five Star according to the terms of the joint venture agreement.

The technical work disclosed in this document was supervised, reviewed and approved by Robert Lunceford, M.Sc., CPG, who is a Qualified Person as defined in National Instrument 43-101 ("NI 43-101").

About Five Star

Five Star consists of 17 mining permits and 8 prospecting permits, which cover an area of approximately 25,065 acres (10,144 hectares) near the settlement of Matthew's Ridge, Guyana. Guyana Frontier acquired its 100% interest in Five Star from two separate underlying vendors, Case Development Company Ltd. and Marcel Waaldijk (the "Underlying Vendors"), with each of the Underlying Vendors currently maintaining a 3% net smelter returns royalty ("NSR") on their respective permits. Each NSR is subject to buy-down provisions. Mulgravian earned its 51% working interest in Five Star from Guyana Frontier by incurring minimum exploration expenditures and property acquisition costs of US$2.0 million, and by purchasing Guyana Frontier common shares and exercising Guyana Frontier common share purchase warrants totalling CDN$630,000.

On May 10, 2011, Guyana Frontier filed a technical report in respect of Five Star on SEDAR compliant with the standards of NI 43-101, available at www.sedar.com
