GUYANA FRONTIER RECEIVES NOTICE OF OPTION EXERCISE FOR FIVE STAR PROJECT

Guyana Frontier Mining Corp. has received notice from Mulgravian Ventures Corp. that Mulgravian has exercised its option in respect of the Five Star property located in Guyana, South America. Under the terms of the option agreement between Guyana Frontier and Mulgravian dated Sept. 10, 2010, Mulgravian has earned its 51-per-cent interest in Guyana Frontier's rights to Five Star, with Guyana Frontier retaining a 49-per-cent interest, and a joint venture has commenced between the two parties. An inaugural joint venture meeting was held in early April, 2012, to discuss and finalize programs and budgets for upcoming exploration at Five Star.

Five Star consists of 17 mining permits and eight prospecting permits, which cover an area of approximately 25,065 acres (10,144 hectares) near the settlement of Matthew's Ridge, Guyana. Five Star is adjacent to Guyana Frontier's Whana and Black Banana properties, which together form a contiguous area of approximately 115,580 acres (47,775 hectares). Guyana Frontier acquired its 100-per-cent interest in Five Star from two separate underlying vendors, Case Development Company Ltd. and Marcel Andrew Waaldijk, with each underlying vendor currently maintaining a 3-per-cent net smelter return royalty on their respective permits. Each NSR is subject to buy-down provisions. Further details on the acquisitions of Five Star and the NSRs can be found in Guyana Frontier's news releases dated April 12, 2010, April 20, 2010, and April 21, 2011.

Mulgravian earned its 51-per-cent working interest in Five Star by incurring exploration expenditures and by making share purchases in Guyana Frontier as follows:

• Mulgravian completed exploration expenditures and certain property acquisition payments to the underlying vendors totalling $2-million (U.S.).
• Mulgravian purchased a total of 700,000 units of Guyana Frontier by way of private placement for gross proceeds of $210,000.
• Mulgravian exercised all of the common share purchase warrants comprising the units for further gross proceeds to Guyana Frontier of $420,000.

The private placement closed on Dec. 10, 2009, with the first tranche of warrants being exercised on Nov. 18, 2010, and the second tranche being exercised on Nov. 18, 2011. Further details of the private placement, the terms of the units and the warrants, and the exercise of certain warrants can be found in Guyana Frontier's news releases of Nov. 4, 2009, Jan. 8, 2010, Nov. 23, 2010, and Nov. 18, 2011.

On March 10, 2011, Mulgravian gave notice to Guyana Frontier that, pursuant to the terms of the option agreement, it wished to assume direct operatorship of the Five Star property. Prior to such date, Mulgravian had retained Guyana Frontier to manage and operate the exploration programs on the Five Star property.

On April 21, 2011, Guyana Frontier announced that it had exercised its option to acquire a 100-per-cent interest in the Five Star-Case property.

On May 10, 2011, Guyana Frontier filed a technical report on SEDAR, compliant with the standards of National Instrument 43-101, in respect of Five Star.

We seek Safe Harbor.
