Luna Gold Corp.'s Board of Directors Approves Phase I Processing Plant Expansion at the Aurizona Gold Mine

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 10, 2012) - Luna Gold Corp. (TSX VENTURE:LGC)(OTCQX:LGCUF)(LMA:LGC) ("Luna" or the "Company") is pleased to announce that its Board of Directors has approved a planned Phase I expansion program to increase annual gold production to a targeted 125,000 ounces of gold at the Company's Aurizona Gold Mine in Brazil.

The Board of Directors approved commencement of an estimated $43.2 million capital expenditure program, as well as a $6.5 million contingency, to complete the Phase I expansion project at Aurizona. The Phase I expansion is now targeted at an annual gold production of 125,000 ounces per year, rather than the 100,000 ounces previously discussed, and will involve low capital cost improvements to the existing Aurizona Mine process plant without either expanding the existing plant's established footprint or impacting current operations. This expansion project is expected to reach completion in Q4 2013. Included in the program is a related updated NI 43-101 technical report for Aurizona, which the Company is targeting for market release at the end of 2012.

Luna is currently negotiating an EPCM contract with an international engineering company that has proven capabilities in Canada and Brazil. Aurizona's increased capacity will be facilitated by the addition of an intense leach reactor, a carbon regeneration kiln, two high rate thickeners, four electrowinning cells, four CIL tanks, and other associated equipment.

John Blake, Luna's President and CEO, stated, "Our Company has the people, the mineral resources, and the financial capacity necessary to unlock Aurizona's significant potential. Within the next sixteen months, this project targets to double gold production from the Aurizona Gold Mine. 2011 and 2012 saw Luna take the steps required to fully prepare for 2013, a year that will witness our Company's emergence as a growing gold producer."

The Company cautions that the potential increased production target for the expansion program discussed above, as well as the Phase I expansion's associated costs, are estimates approved by Luna's Board of Directors. There has been insufficient work to support these statements with a NI 43-101 compliant technical report as of the date of this release.
