           KINROSS EXTENDS ACQUISITION AGREEMENT WITH CROWN RESOURCES
                              TO FIRST QUARTER 2006

TORONTO, ONTARIO, JUNE 1, 2005...KINROSS GOLD CORPORATION (TSX-K; NYSE-KGC)
("Kinross") announced that it has signed an amendment (the "Amendment") with
CROWN RESOURCES CORPORATION (OTCBB-CRCE) ("Crown") to extend the termination
date of the definitive acquisition agreement (the "Agreement") and adjust the
price that Kinross will pay to acquire Crown and its 100%-owned Buckhorn
Mountain gold deposit located in north central Washington State, USA.

With this Amendment, the termination date of the Agreement has been extended to
March 31, 2006, subject to Kinross filing its financial statements no later than
December 31, 2005. The transaction is subject to regulatory approvals, a minimum
two-thirds approval at a special meeting of Crown shareholders and other
customary closing conditions. Both parties are working to close the transaction
as rapidly as possible.

Under the terms of the Amendment, shareholders of Crown will receive 0.34 shares
of Kinross for each share of Crown, an increase of 0.0489 over the original
exchange ratio of 0.2911. A valuation collar has also been agreed upon in which
the aggregate maximum value of Kinross common shares to be issued to Crown
shareholders is US$110 million and the minimum value is US$77.5 million,
excluding shares held by Kinross.

Kinross has also agreed to purchase a US$10.0 million convertible debenture (the
"Debenture") from Crown. The Debenture is convertible into 5.8 million shares of
Crown. In the event the Agreement is terminated, Crown shall have the right to
convert all amounts due under this Debenture by providing 30 days prior notice
to Kinross.

Assuming all of the outstanding Crown warrants and options are converted, a
total of approximately 16.6 million common shares of Kinross will be issued upon
the completion of the transaction.

Tye Burt, President and C.E.O. of Kinross said "We are driving hard to complete
the appropriate filings to make this transaction happen. We remain 100%
committed to the deal, and look forward to starting work on the property as soon
as possible."

The Buckhorn Mountain gold deposit is a high-grade skarn gold deposit located
240 kilometres northwest of Spokane, Washington, approximately 67 kilometers by
road from Kinross' Kettle River gold milling facility. As at December 31, 2003,
Crown had reported total proven and probable reserves of approximately 2.8
million tonnes grading 11 grams per tonne gold and other mineralization of 0.4
million tonnes grading 16 grams per tonne gold as reported in the technical
report prepared by SRK Consulting dated December 2003. The technical report
containing information about reserves and resources is compliant with Canadian
National Instrument 43-101, was filed on SEDAR on December 5, 2003 and can be
found under Kinross' profile at www.sedar.com. With the assistance of an
independent consulting engineering firm,
