            CROWN RESOURCES CORPORATION AND KINROSS GOLD CORPORATION
                          EXTEND ACQUISITION AGREEMENT
           KINROSS TO FUND US$1.0 MILLION PRIVATE PLACEMENT INTO CROWN

DENVER, COLORADO: Crown Resources Corporation (OTCBB-CRCE) ("Crown") announced
that it has signed an Amendment with Kinross Gold Corporation (TSX-K; NYSE-KGC)
("Kinross") to extend the termination date of the previously announced (November
20, 2003) definitive acquisition agreement (the "Agreement") whereby Kinross
will acquire Crown and its 100%-owned Buckhorn Mountain gold deposit located in
north central Washington State, USA, approximately 67 kilometers by road from
Kinross' Kettle River gold milling facility.

With this Amendment, the Agreement has been extended to May 31, 2005. The
Agreement was due to expire on December 31, 2004, but additional time is
necessary for Kinross to file with the Securities and Exchange Commission
("SEC") a definitive registration statement.

Kinross has also agreed to fund a US$1.0 million private placement into Crown.
The private placement calls for Kinross to purchase 511,640 common shares of
Crown for $1.9545 per share. Crown currently has approximately 40.0 million
shares outstanding. This private placement by Kinross will not affect the
exchange ratio of .2911 shares of Kinross common stock for each share of Crown
that was set in the Agreement.

Christopher E. Herald, President and CEO of Crown, stated: "Although Kinross and
Crown are disappointed with the length of time this transaction has taken, this
extension agreement and private placement demonstrates both parties commitment
to seeing this transaction close."
