EXHIBIT 2.10

June 30, 2004

Dear IAMGold Shareholder:

We are pleased to advise that we have substantially increased our offer to purchase all of the outstanding common shares of IAMGold Corporation. Our increased offer is described in more detail in the materials accompanying this letter; however, we have highlighted below certain key aspects of the increased offer for your consideration.

An Improved Offer

Shareholders depositing their IAMGold shares under our increased offer will receive, in exchange for each IAMGold common share deposited and purchased by Golden Star, their choice of either:

1.	1.25 common shares of Golden Star Resources Ltd., or
2.	1.15 common shares of Golden Star plus C$0.50 in cash.

In addition, Golden Star will pay a further C$0.20 in cash per IAMGold share (total cash of approximately US$22 million) to IAMGold shareholders whose shares are taken up under the offer when we definitively determine that no break fee is paid or payable to Wheaton River Minerals Ltd. in accordance with the Amended and Restated Arrangement Agreement between IAMGold and Wheaton River dated April 29, 2004, as may be amended.

A Compelling Premium

Our increased offer (excluding the additional C$0.20 per IAMGold share cash payment) represents a premium of 23% to the closing price of IAMGold common shares on May 27, 2004, the last trading day prior to the announcement of Golden Star’s initial proposal.

A Better Proposal For IAMGold Shareholders

Based on the closing share prices for Golden Star and IAMGold on March 30, 2004, the increased offer is equivalent to C$11.15 per IAMGold common share, which is significantly higher than the C$9.82 per IAMGold share “Superior Proposal” threshold in the IAMGold/Wheaton River Arrangement Agreement.

A Strong and Focused Pure-Gold Company

As you know, we believe that the combination of Golden Star and IAMGold is a unique opportunity to create an intermediate gold producer with a portfolio of profitable gold mining operations, development projects and exploration properties in West Africa. We believe that West Africa is host to some of the world’s most geologically prospective areas for future gold discoveries and development of large, low cost mining operations.
