矿产储量声明注释：
(1) The stated Mineral Reserve for Bogoso/Prestea includes Prestea South,
Pampe and Mampon.
(2) The stated Mineral Reserve for Wassa/HBB includes the Hwini-Butre and
Benso properties.
(3) The stated Mineral Reserves have been prepared in accordance with
Canada's National Instrument 43-101 Standards of Disclosure for Mineral
Projects and are classified in accordance with the Canadian Institute of
Mining, Metallurgy and Petroleum's "CIM Definition Standards -- For
Mineral Resources and Mineral Reserves". Mineral Reserves are equivalent
to Proven and Probable Reserves as defined by the SEC Industry Guide 7.
Mineral Reserve estimates reflect the Company's reasonable expectation
that all necessary permits and approvals will be obtained and
maintained. Mining dilution and mining recovery vary by deposit and have
been applied in estimating the Mineral Reserves.
(4) The 2010 Mineral Reserves were prepared under the supervision of Mr.
Karl Smith, Vice President Technical Services for the Company. Mr. Smith
is a "Qualified Person" as defined by Canada's National Instrument 43-
101. The 2011 Mineral Reserves were prepared under the supervision of
Dr. Martin Raffield, Senior Vice President Technical Services for the
Company. Dr. Raffield is a "Qualified Person" as defined by Canada's
National Instrument 43-101.
(5) The Mineral Reserves at December 31, 2011 were estimated using a gold
price of $1,250 per ounce, which is approximately equal to the three-
year average gold price. At December 31, 2010, Mineral Reserves were
estimated using a gold price of $1,025 per ounce.
(6) The terms "non-refractory" and "refractory" refer to the metallurgical
characteristics of the ore and are defined in the Glossary of Terms. We
plan to process the refractory ore in our sulfide bio-oxidation plant at
Bogoso and to process the non-refractory ore using our more traditional
gravity, flotation and/or cyanidation techniques.
(7) The slope angles of all pit designs are based on geo-technical criteria
as established by external consultants. The size and shape of the pit
designs are guided by consideration of the results from a pit
optimization program. The parameters for the pit optimization program
are based on a gold price of $1,250 per ounce, historical and projected
operating costs at Bogoso/Prestea, Wassa and Hwini-Butre and Benso.
Metallurgical recoveries are based on historical performance or
estimated from test work and typically range from 80% to 95% for non-
refractory ores and from 70% to 85% for refractory ores. A government
royalty of 5% is allowed as are other applicable royalties.
(8) Numbers may not add due to rounding.

矿产储量调节说明：
(1) Gold Price Increase represents changes resulting from an increase in
gold price used in the Mineral Reserve estimates from $1,025 per ounce
in 2010 to $1,250 per ounce in 2011.
(2) Exploration Changes include changes due to geological modeling, data
interpretation and resource block modeling methodology as well as
exploration discovery of new mineralization.
(3) Mining Depletion represents the 2010 Mineral Reserve within the volume
mined in 2011 with adjustments to account for stockpile addition and
depletions during 2011 and therefore does not correspond with 2011
actual gold production.
(4) Engineering includes changes as a result of changes in operating costs,
mining dilution and recovery assumptions, metallurgical recoveries, pit
slope angles and other mine design and permitting considerations.
(5) Numbers may not add due to rounding.
(6) Pit design changes that are primarily due to a higher gold price are
included here.
(7) Pit design changes that are primarily due to exploration discoveries are
included here.
由于公司向NI 43-101和NI 43-101报告其矿产储量 SEC行业指南7标准，其矿物是可能的 保留数字在两者之间有所不同。发生这种差异的地方 它将源于报告矿物的不同要求 储量。例如， NI 43-101 的最低要求是 矿产储量由预可行性研究支持，而SEC 行业指南 7 需要详细可行性研究的支持 这表明经济开采是合理的。对于 2011年12月31日和2010年的矿产储量，没有 根据NI 43-101披露的矿产储量之间的差异 以及根据 SEC 行业指南 7 披露的内容，因此没有 提供对账。
非储量 - 测量和指示矿产资源
致美国投资者的关于测量和估计的警示说明 指示矿产资源 本节使用术语“测量 矿产资源“和”指示矿产资源”。公司简介 建议美国投资者，虽然这些条款得到认可，并且 加拿大法规要求，美国证券交易 委员会不承认他们。美国投资者应注意不要 假设这些矿床中的任何部分或全部 类别将永远转换为矿产储量。
以下报告的测量和指示矿产资源量是 不包括已探明和可能的矿产储量，如上所示 并按照 加拿大国家文书43-101。

测量和指示矿产资源的说明：
(1) The Mineral Resources for Bogoso/Prestea include Pampe and Mampon.
(2) The Mineral Resources were estimated in accordance with the definitions
and requirements of Canada's National Instrument 43-101. The Mineral
Resources are equivalent to Mineralized Material as defined by the SEC
Industry Guide 7.
(3) The Mineral Resources were estimated using optimized pit shells at a
gold price of $1,500 per ounce from which the Mineral Reserves have been
subtracted. Other than gold price, the same optimized pit shell
parameters and modifying factors used to determine the Mineral Reserves
were used to determine the Mineral Resources. In 2010, we used a gold
price of $1,300 per ounce for the optimized shell. The Prestea
Underground resource was estimated using a $1,500 per ounce gold price
and operating cost estimates using an economic gold cut-off of 2.3 g/t.
In 2010, we used a gold price of $1,300 per ounce for the optimized
shell.
(4) The Mineral Resources are not included in and are in addition to the
Mineral Reserves described above.
(5) The Qualified Person reviewing and validating the estimation of the
Mineral Resources is S. Mitchel Wasel, Golden Star Resources Vice
President of Exploration.
(6) Numbers may not add due to rounding.
(7) The Father Brown underground resource has been estimated below the
$1,500 pit shell down to the 750 meters (m) elevation using an economic
gold grade cut-off of 2.2 g/t, which we believe would be the lower cut-
off for underground.
(8) The Buesichem Underground resource has been estimated below the $1,500
pit shell down to 4500m elevation using an economic gold grade cut-off
of 2.8 g/t Au.
(9) The 2010 totals include indicated resources of 2.7 million tonnes at a
grade of 1.75 g/t at the Goulagou property in Burkina Faso. The 2011
totals exclude Goulagou's resources because the Goulagou property was
sold in February 2012.
非储量 - 推断矿产资源
