    NOTES TO THE MINERAL RESOURCE STATEMENT:



    1.  The Mineral Resource Statement has been prepared in accordance with

        the definitions and guidelines of the Canadian Institute of Mining,

        Metallurgy and Petroleum definitions and guidelines adopted in August

        2000.



    2.  The stated Total Measured and Indicated Resource is equivalent to

        Mineralized Material as defined by the US Securities Exchange

        Commission.



    3.  The Mineral Resource Statement was prepared by geoscientists working

        for Golden Star with the assistance of a number of specialist

        consultants under the supervision of Mr. S. Mitchel Wasel an employee

        of Golden Star, who following the acquisition of the Bogoso gold mine

        in 1999 was appointed Exploration Manager for Bogoso Gold Limited. Mr.

        Wasel is a qualified geologist with 13 years of experience in gold and

        base metal exploration and is a Member of the Australasian Institute

        of Mining and Metallurgy. Mr. Wasel is the Company's Qualified Person

        for this press release.



    4.  An independent technical report required by the Canadian Securities

        Administrators for compliance with Canadian National Instrument 43-101

        is being prepared under the supervision of Mr. Keith McCandlish,

        P.Geol. of Associated Mining Consultants Ltd. Mr. McCandlish satisfies

        the requirements of a Qualified Person defined in NI 43-101.



    5.  The "oxide", "transition", and "primary" portions of the Mineral

        Resource are non-refractory and amenable to processing in the existing

        Bogoso processing plant. The "refractory sulfide" portion of the

        Mineral Resource is refractory and would only be amenable to

        processing using refractory ore processing methods. Golden Star has

        substantially completed a detailed feasibility study for the upgrading

        of the Bogoso processing plant for the processing of refractory ores

        using a stirred tank bio-oxidation method.



    6.  The Mineral Resources have been determined using a cut-off grade based

        on (i) a gold price of US$300 per ounce, and (ii) mining and

        processing costs and recoveries actually being achieved at Bogoso, or

        derived from appropriate testwork.



    7.  The Mineral Resources are reported as in-situ Mineral Resources with

        no allowance for mining dilution or mining loss.



    8.  Individual one-metre assay results have been subjected to a top cut

        equal to the 97.5 percentile of the relevant database. The one-metre

        intersection grades have then been composited into two metre averages

        for geostatistical modeling using either ordinary Kriging or inverse

        distance squared algorithms.



    9.  The Mineral Resource Statement incorporates work that was undertaken

        by Golden Star and work carried out by previous owners of the Bogoso

        and Prestea properties. The work carried out by Golden Star has been

        submitted to a quality control program comprised of rigorous controls

        on the site and a program of duplication and re-evaluation of analysis

        and control samples, including verification of 10% of the samples

        originating in the mineralized zone. The majority of samples,

        approximately 90%, were processed in independent laboratories with the

        remaining samples analysed at Golden Star's on-site laboratory at

        Bogoso. All analysis was done using a fire assay pre-concentration

        with either atomic absorption or gravimetric finishes.



        The work carried out by others has been vetted and validated by

        independent consultants and has been verified by Golden Star. This

        verification has confirmed that the work was submitted to a quality

        control program comprised of rigorous controls on the site and a

        program of duplication and re-evaluation of analysis and control

        samples, including verification of 10% of the samples originating in

        the mineralized zone. The majority of samples, approximately 90%, were

        processed in independent laboratories using the fire assay technique

        with an atomic absorption finish. Any drill results that could not be

        verified or did not meet the above criteria were excluded from the

        Mineral Resource determination.



    10. The geology of the Bogoso and Prestea properties is broadly similar

        and is as reported in Golden Star's 10-K filing to the US Securities

        and Exchange Commission. There is however a subtle change in the

        mineralization between that found on the northern part of the Prestea

        concession (and the Bogoso Concession) with that on the southern

        portion of the Prestea concession. The broad crush zone with

        refractory sulfides at depth, characteristic of the northern

        mineralization, is replaced by more discrete, higher-grade, shear type

        mineralization, with non-refractory sulfides at depth, in the south.

Golden Star holds a 90% equity interest in the Bogoso gold mine in Ghana,
a 30% equity interest in the Omai gold mine in Guyana, and a 50% interest in
the Gross Rosebel gold project in Suriname.
In addition, the Company has
other gold and diamond exploration interests in the Guiana Shield in South
America and in West Africa.
Golden Star has approximately 47 million shares
outstanding.
The Company is listed on the Toronto Stock Exchange under the
symbol ``GSC'' and trades on the OTC Bulletin Board under the symbol ``GSRSF''.

The statements contained in this press release are both historical and
forward-looking in nature. The forward-looking statements involve risks and
uncertainties including those relating to exploration, the establishment of
reserves, the recovery of any reserves, future gold production, future costs
of production, future permitting and future operations. Please refer to a
discussion of these and other risk factors in Golden Star's Form 10-K and
other Securities and Exchange Commission Filings.
