PROTECT YOUR INVESTMENT   STOP HARMONY’S OFFER FOR GOLD FIELDS   VOTE IN FAVOUR OF THE IAMGOLD TRANSACTION	Postnet Suite 252 Private Bag X30500 Houghton, 2041 South Africa Tel +27 11 644-2400 Dir +27 11 644-2444 Fax +27 11 484-0682 www.goldfields.co.za

Dear Gold Fields Shareholder,

Over the past six weeks you have been inundated with misinformation in support of Harmony’s value destroying, hostile and coercive bid for our great company.

Central to Harmony’s attack has been the Norilsk supported demand that our proposed reverse takeover of IAMGold be blocked, thereby denying you, the Gold Fields shareholder, the opportunity to create and own a great new gold investment: Gold Fields International.

On 7^th December, you have the opportunity make this vision a reality by voting yes for the creation of Gold Fields International.

Over the past few weeks we have actively canvassed the majority of our shareholders and they have told us in no uncertain terms:

“Gold Fields Shareholders want Gold Fields International!”

The proposed reverse takeover of IAMGold by Gold Fields, to create Gold Fields International as the 70% owned and controlled international subsidiary and growth vehicle of Gold Fields, is part of the ongoing internationalisation strategy of Gold Fields, aimed at creating a truly competitive global player in the gold industry. Gold Fields International will be one of the world’s top gold producers (fourth largest in North America and seventh largest in the world); with an enviable set of global assets; and with the most aggressive growth profile in the industry.

Your Board remains unwavering in its belief in the benefits, strategic rationale and value of the proposed transaction for Gold Fields’ shareholders.

Directors: C M T Thompson* (Chairman), A J Wright (Deputy Chairman), I D Cockerill^† (Chief Executive Officer), K Ansah^#, G J Gerwel, N J Holland^† (Chief Financial Officer), J M McMahon^†, G R Parker^‡, R L Pennant-Rea^†, P J Ryan, T M G Sexwale, B R van Rooyen, C I von Christierson

In October 2004, South Africa’s Minister of Finance announced a series of relaxations to South Africa’s exchange control legislation. We welcome the changes because, far from making Gold Fields International redundant as was suggested by Harmony, the proposed changes will make it easier for Gold Fields and Gold Fields International to achieve its international growth objectives. If anything they enhance the strategic rationale for the transaction: creating a vehicle with direct access to international equity and debt markets, able to compete more effectively on a global stage and deliver the aggressive growth that Gold Fields International is expected to deliver.

VOTE FOR GOLD FIELDS INTERNATIONAL ON THE GOLD PROXY CARD.

Our purpose in proposing the creation of Gold Fields International is:

• To create a vehicle capable of generating dynamic international growth in which you, the Gold Fields shareholder, will participate directly through your 70% controlling stake;

• To ensure that you benefit directly from the premium share rating typically given to North American listed gold companies. We have already seen that premium rating come through in the share prices of both Gold Fields and IAMGold (which is now a proxy for Gold Fields International — see page 3); and

• To let you benefit from the potential value creation derived from a company that is staffed and focused on aggressive growth, that is domiciled at the centre of the deal flow, and has ready access to the capital markets and the ability to respond rapidly to opportunities as they arise.

The transaction is well thought through, robust and creates an exciting growth vehicle:

• Gold Fields will fully CONSOLIDATE and CONTROL Gold Fields International, thereby enabling Gold Fields shareholders to benefit from future growth and value creation. We will have:

• 70% ownership of Gold Fields International

• 7 out of 10 board members

• Gold Fields proven management team

• Top-up rights to mitigate dilution

• Anticipated production of approximately 2 million ounces in 2005 is projected to increase to approximately 3.5 million gold equivalent ounces in 2007 through our existing organic growth projects and our exciting, high impact and fully funded project pipeline.

• Proven and probable attributable gold reserves of 19.2 million ounces, measured and indicated resources (including reserves) of 25.9 million ounces, and additional inferred resources of 9.1 million ounces.

• Strong pipeline of near-term development projects and an extensive portfolio of attractive advanced-stage exploration projects.

• Unhedged production and reserves giving direct and full exposure to the gold price.

• Geographically diversified asset base including operations and projects in Australia, West Africa, China, Europe and the Americas.

• Strong balance sheet with approximately US$450 million in cash, cash equivalents and bullion and anticipated operating cash flow in financial year 2005 of approximately US$251 million (assuming a gold price of US$400 per ounce).

• Experienced management team drawn from Gold Fields and IAMGold with a well established international mine development and operating track record.

Control of Gold Fields International will be firmly in the hands of
Gold Fields’ shareholders who will own 70% of the company.
 
We urge you to vote FOR the reverse takeover of IAMGold on the Gold
proxy card.
 
Every single vote counts.

Your Board believes Harmony has used unsubstantiated claims to create uncertainty regarding the proposed reverse takeover to create Gold Fields International.

For example:

• Harmony claims that we are giving up control of our international assets, with most of the cash and board seats going to IAMGold. This is not true. You, the Gold Fields shareholders, will have a 70% controlling ownership of Gold Fields International; 7 out of the 10 board seats; and greater cash and bullion reserves than you have now.

• Harmony claims this transaction is a disposal of assets. Again, this is wrong. The transaction is a reverse takeover by Gold Fields of IAMGold and its 400,000 ounces per annum of quality international production, cash reserves and royalty stream, with Gold Fields ending up with 70% ownership and control of the larger resulting company.

• Harmony’s claims that the creation of Gold Fields International will lead to value leakage for Gold Fields shareholders. Yet another misrepresentation. To illustrate how much value this transaction has already created for you, the Gold Fields shareholder:

• From the date of announcement of the combination (10 August 2004), until 14 October, 2004, IAMGold’s share price (which was now acting as a proxy for Gold Fields International) increased by 60%. Gold Fields’ 70% share of Gold Fields International saw an implied increase in value of over US$1 billion.

• Over the same period the Gold Fields share price increased by 30% implying a significant re-rating against its peer group as the benefits of the transaction flowed through to the parent company.

• Over this same period the Harmony share price increased by only 23%, despite a cut in South African interest rates. Judging by previous performances one would have expected Harmony to outperform Gold Fields. AngloGold’s share price increased by 11% over the same period.

Gold Fields International is set to grow and create significantly more value for Gold Fields shareholders.

Thank you for your support during these challenging times. We have a great company and the creation of Gold Fields International through the reverse takeover of IAMGold will bring even greater opportunities. On behalf of the entire Board of Directors of Gold Fields, I urge you to VOTE FOR creating more value.

VOTE FOR THE REVERSE TAKEOVER OF IAMGold!
 
VOTE FOR GOLD FIELDS INTERNATIONAL!
 
VOTE FOR VALUE!

Yours sincerely,

Ian Cockerill
Chief Executive
