Golden Valley Mines Ltd./New Option Agreement Signed: Centremaque Prospect-Boulamaque Township, Quebec

Golden Valley Mines Ltd. ("Golden Valley" or the "Company")(TSX VENTURE:GZZ) is
pleased to announce that it has entered into an option agreement with Monarch
Energy Limited ("Monarch Energy"), in respect of its Centremaque Prospect (the
"Property") located in Bourlamaque Township, 6 km southeast of Val-d'Or, Quebec.


Pursuant to the terms of the agreement, Monarch Energy can earn up to a 70%
interest in the Centremaque Prospect by incurring aggregate exploration
expenditures of $2,250,000 over three years ($250,000 in year-1; $500,000 in
year-2 and $1,500,000 in year-3). In addition, Monarch Energy has to complete a
Definitive Feasibility Study for the Property at its sole cost within 10 years
of signing, leaving Golden Valley with a free carried interest of 30% in the
Property. Monarch must also issue to Golden Valley such number of shares in the
capital of Monarch Energy as is equal to 9.9% of its issued capital on the later
of TSXV approval and August 31, 2011, together with a $35,000 cash payment and
reimbursement of its legal expenses due within 6-months of signing. Golden
Valley will be operator during the option phase.


The Centremaque Gold Property is comprised of six mining claims, located
approximately 6 km southeast of the town of Val-d'Or, Quebec along the
Cadillac-Larder Fault Zone of the Abitibi Greenstone Belt. At least twenty-seven
(27) diamond drillcore holes (5,865 m) are reported to be drilled on the
property between 1940 and 1994 with the majority of the historical drilling
taking place in 1947 and 1987-1988. The drillholes encountered numerous
intersections assaying gold grades greater than 1.0 g/t Au and including an
intersection grading 15.87 g/t Au over 0.31 m (Ministere de l'Energie et des
Ressources naturelles, Documentation technique GM 04715, GM 06851-A, GM 06851-B,
GM 36084, GM 46225, GM 47483, GM 52639, GM 58144).


The Property is located within the Val-d'Or gold mining camp, located
approximately 6 km to the south (of the Sigma and Lamaque Mines where from 1937
to 2000, the Sigma Underground Mine continuously operated and produced 24.8 Mt
grading 5.48 g/t Au totalling of 4.4 million oz Au. The adjacent Lamaque
underground mine, which is part of the same vein system as Sigma, produced 24.2
Mt grading 5.81 g/t Au totalling of 4.55 million oz Au was closed due to low
gold prices - Century Mining Website, August 2011). Exploration activity in the
area of the Property is high with a number of companies engaged in large-scale
exploration programs on adjacent and nearby claims. 


Recent geophysical surveying conducted by Golden Valley Mines over the claims
(magnetic and Induced Polarization surveys) along lines spaced 50 metres apart,
have outlined several anomalies warranting further drill testing based on an
initial interpretation of the data.


The first years' proposed work program will include a compilation of
pre-existing exploration data and completion of a 3-D drillhole model of the
historical drill data and the drilling of approximately 1,400 metres of new
drill core to confirm previous assays and evaluate the new geophysical targets.


About Golden Valley Mines Ltd.: The Company typically tests initial grassroots
targets while owning a 100% interest therein and then seeks partners to continue
exploration funding. This allows the Company to carry on its generative programs
and systematic exploration efforts at other majority-owned grassroots projects.
The Company (together with its various subsidiaries) holds majority property
interests in projects in Canada (Saskatchewan, Ontario and Quebec) and in the
Republic of Sierra Leone in West Africa.
