MacMillan Gold Options The La Sarita Project in Mexico

TORONTO, ONTARIO, Aug 27 (MARKET WIRE) --
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 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.
