Vancouver, Canada, February 14, 2012 - Guyana Frontier Mining Corp. (TSX-V: GYG) ("Guyana Frontier") is pleased to announce the commencement of a 3,000 metre Diamond drilling program at the Marudi Mountain Gold Project ("Marudi Mountain") in southern Guyana, South America. The program consists of 10 to 15 holes to depths of between 150 to 300 metres to test the saprolite and bedrock zones present in two areas of the Marudi Mountain property. Two holes are planned for the Mazoa Hill target area where drilling by previous explorers identified a substantial zone of gold mineralization. The remaining holes are planned for the Marudi North target area, where Guyana Frontier identified prospective drill targets from its extensive 2011 trenching program (see Guyana Frontier News Release, October 31, 2011).

The drilling program is expected to continue into April 2012. To view a map depicting the locations of both proposed 2012 drill holes and historical drill holes, please visit Guyana Frontier's website at www.guyanafrontier.com

The technical disclosure in this news release has been reviewed and approved by Mr. Locke Goldsmith, M. Sc., P.Eng., P.Geo., a Qualified Person as defined in National Instrument 43-101, and an independent contractor to Guyana Frontier.

About Marudi Mountain

Marudi Mountain consists of one Mining Licence totaling 13,502 acres (5,464 hectares) located in southern Guyana approximately 500 kilometres (330 miles) from the capital city of Georgetown. Guyana Frontier holds a 100% interest in the Project, subject to a 2% net smelter returns royalty ("NSR").

Guyana Frontier also holds a 100% interest in the adjacent Paint Mountain property ("Paint Mountain"), subject to a 2% NSR. Paint Mountain consists of one Prospecting Licence totaling 8,848 acres (3,581 hectares) and remains largely underexplored. Guyana Frontier recently commenced surface exploration at Paint Mountain. Rock and stream sediment samples have been collected and sent for geochemical analysis and petrography. A portion of the property has been selected for detailed mapping and sampling on the basis of favourable geology and the presence of artisanal alluvial gold miners. Airborne geophysical surveys are planned for both Marudi Mountain and the Paint Mountain projects in early 2012.

Often, but not always, forward-looking statements can be identified by the use of words such as "plans", "planning", "planned", "expects" or "looking forward", "does not expect", "continues", "scheduled", "estimates", "forecasts", "intends", "potential", "anticipates", "does not anticipate", or "belief", or describes a "goal", or variation of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will" be taken, occur or be achieved.

Forward-looking statements are based on a number of material factors and assumptions, including, the result of drilling and exploration activities, that contracted parties provide goods and/or services on the agreed timeframes, that equipment necessary for exploration is available as scheduled and does not incur unforeseen break downs, that no labour shortages or delays are incurred, that plant and equipment function as specified, that no unusual geological or technical problems occur, and that laboratory and other related services are available and perform as contracted. Forward-looking statements involve known and unknown risks, future events, conditions, uncertainties and other factors which may cause the actual results, performance or achievements to be materially different from any future results, prediction, projection, forecast, performance or achievements expressed or implied by the forward-looking statements. Such factors include, among others, the interpretation and actual results of current exploration activities; changes in project parameters as plans continue to be refined; the existence of weather conditions suitable for exploration activities; future prices of minerals; possible variations in grade or recovery rates; failure of equipment or processes to operate as anticipated; the failure of contracted parties to perform; labour disputes and other risks of the mining industry; delays in obtaining governmental approvals or financing or in the completion of exploration, as well as those factors disclosed in the company's publicly filed documents. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be as anticipated, estimated or intended.
