PRESS RELEASE

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,



Kinross is currently updating the Buckhorn Mountain reserve and mineralized material

estimates.
