Dear Shareholder:

        As you know, the Special General Meeting of Shareholders of ASA
(Bermuda) Limited will be held on June 9, 2005. WE NEED YOUR VOTE FOR THE
COMPANY TO SECURE APPROVAL OF THE IMPORTANT PROPOSALS BEING CONSIDERED AT THE
MEETING. YOUR PARTICIPATION IS CRITICAL - PLEASE PARTICIPATE BY VOTING YOUR
SHARES TODAY. The vote of all stockholders, large and small, is important.

                         WHY ARE CHANGES BEING PROPOSED

        The Company is subject to a number of fundamental investment policies
relating to the diversification of its portfolio and the concentration of its
investments inside and outside of South Africa. The Board of Directors is
proposing certain changes to these policies that it believes will provide the
Company with greater investment flexibility to respond to significant structural
changes in the gold mining industry.

        Specifically, the Board believes the proposed changes are necessary due
to the:

            .   substantial decrease in South African gold production and the
                significant increase in gold production outside of South Africa;
                and

            .   widespread consolidation in the gold mining industry resulting
                in a decrease in the number of South African issuers in which
                the Company can invest.

        These structural changes are evidenced by the following facts:

            .   South African gold production has declined from approximately
                1000 tonnes in 1970, accounting for more than 60% of worldwide
                production, to approximately 375 tonnes in 2003, or roughly 17%
                of worldwide production;

            .   the number of South African gold mining companies listed on the
                JSE Securities Exchange South Africa has declined from over 50
                in 1994 to approximately a dozen in 2004 due to consolidation,
                only three of which are of a size that management believes is
                appropriate for the Company's portfolio; and

            .   large gold producers are currently focused on exploration and
                development in regions with better prospects and lower
                production costs than South Africa.



               CURRENT POLICIES PUT THE COMPANY AT A DISADVANTAGE.

        The Company's current policies pertaining to diversification of its
portfolio and the concentration of its investments put the Company at a
disadvantage compared to other gold and precious minerals funds that are not
similarly limited by their investment policies. These policies have not kept up
with industry changes and prevent the Company from adapting to these changes.
The current policies restrict the Company by:

            .   limiting the amount the Company can invest in the securities of
                a single issuer; and

            .   limiting the amount the Company can invest outside of
                South Africa.

        It is imperative to increase the Company's investment flexibility by
eliminating these restrictions so that the Company can pursue the best precious
minerals investments on a global scale. Shareholders should be assured that the
main focus of the Company is to remain invested in companies involved in the
mining of gold.

                 WE NEED YOUR VOTE IN SUPPORT OF THESE CHANGES.

                YOU ARE URGED TO VOTE YOUR SHARES WITHOUT DELAY.

        PLEASE READ THE PROXY STATEMENT CAREFULLY BECAUSE IT CONTAINS IMPORTANT
INFORMATION ABOUT THESE AND OTHER PROPOSED POLICY CHANGES.

        The proposals to be acted on at the meeting have been carefully
considered by the Board of Directors. The Board believes that these proposals
are in the best interests of the Company and its shareholders and unanimously
recommends that you vote FOR each proposal. Please vote your shares promptly.
