advance our infrastructure, with the long-term goal of transforming
Prestea Underground into a modern, mechanized mine and a key
contributor to lower cost gold production going forward," said Sam
Coetzer, President and CEO. "We are preparing for early production
from existing infrastructure and remnant stopes in the Central Shaft
area as allowed by these permits. We are also proceeding with a
feasibility study on the development of the West Reef area,
completion of which is expected in the first half of 2013." 
Highlights of the West Reef Preliminary Economic Assessment (PEA)*
completed in 2012: 

--  An Indicated Mineral Resource of 874,000 tonnes grading 18.07 grams
    per tonne (g/t) for 508,000 ounces of gold, and the deposit is open
    along strike and down dip;
--  An Inferred Mineral Resource of 510,000 tonnes grading 11.58 g/t for
    190,000 ounces of gold, and the deposit is open along strike and down
--  Results from ongoing drilling programs on the 17 and 24 levels of the
    West Reef area will be incorporated into the information being
    gathered for the West Reef feasibility study;
--  The PEA contemplates a 1,200 tonnes per day mining operation
    (including mineralized material from development);
--  Currently delineated West Reef material is expected to be processed at
    the Bogoso non-refractory processing plant and produce up to 97,000
    ounces of gold per year at full operation, with estimated life-of-mine
    gold production of 437,000 ounces;
--  Life-of-mine cash operating costs (before royalty and taxes) are
    estimated at $600 to $700 per ounce;
--  Capital costs, including a decline and hoisting shaft, are estimated

Cautionary Note to Investors Concerning Estimates of "Indicated
Mineral Resources" and Inferred Mineral Resources" 
This press release uses the terms "Indicated Mineral Resources" and
"Inferred Mineral Resources". The Company advises US investors that
while these terms are recognized and required by National Instrument
43-101, the US Securities and Exchange Commission ("SEC") does not
recognize them. US investors are cautioned not to assume that any
part or all of the mineral deposits in these categories will ever be
converted into a higher category or into mineral reserves. Inferred
Mineral Resources have a great amount of uncertainty as to their
existence, and great uncertainty as to their economic and legal
feasibility. US investors are cautioned not to assume that any part
or all of the Inferred Mineral Resource exists, or is economically or
legally mineable. Also, disclosure of contained ounces is permitted
under Canadian regulations; however the SEC generally requires
mineral resource information to be reported as in-place tonnage and
grade. The PEA is preliminary in nature, it includes Inferred Mineral
Resources that are considered too speculative geologically to have
economic considerations applied to them that would enable them to be
categorized as mineral reserves, there is no certainty that the PEA
will be realized and mineral resources that are not mineral reserves
do not have demonstrated economic viability.

contained in this news release are forward-looking statements within
the meaning of the Private Securities Litigation Reform Act of 1995
and other applicable securities laws. Investors are cautioned that
forward-looking statements are inherently uncertain and involve risks
and uncertainties that could cause actual results to differ

achieve early production in the Central Shaft area; plans to
transform Prestea Underground into a modern, mechanized mine and
contributor to lower cost gold production; plans to review early
production options; plans to complete a feasibility study on the West
Reef including plans to incorporate results from ongoing drilling
programs on the 17 and 24 levels of Prestea Underground into such
feasibility study, as well as the expected timing of the feasibility

plant; and estimates of processing rates, gold production, operating
costs, capital costs, net present value and internal rates of return
are forward looking statements. Factors that could cause actual
results to differ materially include timing of and unexpected events
at Prestea Mine and the Bogoso/Prestea oxide and sulfide processing
plants; variations in ore grade, tonnes mined, crushed or milled;
variations in relative amounts of refractory, non-refractory and
transition ores; delay or failure to receive board or government
