TORONTO, ONTARIO - (Aug. 27, 2008) - George A. Brown, President and CEO of MacMillan Gold Corp. (TSX VENTURE:MMG), is pleased to announce that MacMillan has signed a Mineral Property Option Agreement with the owner of the La Sarita Project in the State of Sonora in Mexico.

Mr. Kenneth Shonk, P.Geo., Vice President of Mexico Exploration and Mr. William Hamilton, P.Geo., Manager of Exploration are both Qualified Persons under the meaning of National Instrument 43-101 and are responsible for all technical information contained in this news release.

The La Sarita covers a substantial portion of an extensive copper silver skarn system located in the low range of hills between 20 and 25 kilometres southeast of Moctezuma in Sonora. The large area of oxidized and leached skarn suggests that the granitic intrusive that is exposed at lower elevations underlies the skarn at shallow depths along a low angle contact. Based on the topographic range of skarn exposures observed, the depth of the skarn-intrusive contact is anticipated to be at depths of 50 to 300 metres. The extensive area of this skarn system provides exploration potential for significant tonnages with low strip ratios. The geological target is thought to have significant potential to explore and develop an oxide copper target with the potential for expansion by adding a sulphide copper-silver target below the oxide layer. There are three genetically related exploration targets on this property:

- supergene copper-oxide mineralization in the near surface oxide zones at 0 to 50 metres

- hypogene copper-silver sulphide mineralization in exoskarn at depths of 20 to 300 metres

- hypogene copper-silver sulphide mineralization in endoskarn developed in xenolith contaminated intrusives at depths of 100 to 500+ metres

The La Sarita option agreement covers three concessions totaling 809.5 hectares. MacMillan has the right to earn a 100% interest subject to a Net Smelter Return ("NSR") of up to 3% on silver and copper and 2% on other metals. The percentage of the NSR is based on a sliding scale for the underlying price of the commodities and can be reduced by 0.5% for each lump sum payment of US$250,000. The entire NSR may be purchased for US$1,500,000. MacMillan may earn the 100% interest by making cash option payments totaling US$371,000 by December 2012 of which US$47,000 has been paid including the US$20,000 due on signing, the US$15,000 due on the termination of the due diligence period, and the monthly payments of US$3,000 for May to August. MacMillan is also required to incur up to US$1,750,000 in expenditures on the property by February 2013 of which US$80,000 must be incurred by February 2009. MacMillan is entitled to claim a 10% administration fee in reporting these required expenditures. MacMillan is allowed at its sole option to accelerate the 100% earn in after the first anniversary and until the fifth anniversary by making a single lump sum payment of up to US$1,750,000.

The Company is pleased to add this property of geological merit with excellent exploration potential to our list of active projects.
