           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.

CROWN RESOURCES CORPORATION AND KINROSS GOLD CORPORATION MODIFY EXCHANGE RATIO
AND EXTEND ACQUISITION AGREEMENT 
Wednesday June 1, 10:07 am ET


KINROSS TO FUND US$10.0 MILLION FINANCING INTO CROWN; CROWN TO CONSIDER A
SPECIAL DIVIDEND

DENVER--(BUSINESS WIRE)--June 1, 2005-- Crown Resources Corporation (OTCBB:CRCE
- NEWS; "Crown") announced that it has signed a Fourth Amendment ("Amendment")
with Kinross Gold Corporation (TSX:K - NEWS; NYSE:KGC - NEWS; "Kinross") to
extend the termination date of the 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.

Under the terms of the Amendment to the Agreement, shareholders of Crown will
receive 0.34 shares of Kinross for each share of Crown, an increase to the
original exchange ratio of 0.2911. A valuation collar has also been agreed upon
whereby the aggregate maximum value of Kinross common shares to be issued to
Crown shareholders is US$110 million and the minimum value is $77.5 million.
Crown shares held by Kinross are not included in the valuation calculation.

The transaction is subject to regulatory approvals, a minimum two-thirds
approval at a special meeting of Crown shareholders and other customary closing
conditions. With this Amendment, the termination date of the Agreement has been
extended to March 31, 2006 except that, if Kinross has not filed its 2004
audited financial statements with the Securities and Exchange Commission on or
before December 31, 2005, the termination date of the Agreement will be December
31, 2005. The Agreement was due to expire on May 31, 2005, but additional time
is necessary for Kinross to complete its corporate filings with the Securities
and Exchange Commission ("SEC") and completion and SEC acceptance of a
definitive registration statement.

Kinross has also agreed to fund a US$10.0 million convertible debenture
("Debenture") investment into Crown. Funds from the investment may be used to
pay a special dividend to Crown shareholders of up to $0.21 per share of Crown
before September 30, 2005. The special dividend, if one is declared, will be
determined by Crown's board of directors based upon the future financial
requirements of Crown. Payment of the special dividend will change the tax
status of the transaction from tax-deferred to taxable. Neither the financing
nor any conversion of the Debenture will affect the exchange ratio of 0.34
shares of Kinross common stock for each share of Crown that was set in the
Amendment.

The Debenture will have a term of five years, an interest rate of 4% payable
annually with a provision to forego interest for the first two annual payments,
at Crown's election. The Debenture is convertible into 5.8 million shares of
Crown, plus accrued interest. In the event the Agreement is terminated other
than as a result of a default by Crown, Crown shall have the right to convert
all amounts due under the Debenture by providing 30 days prior notice to
Kinross.

Crown currently has approximately 40.0 million shares outstanding and 48.3
million on a fully diluted basis, both amounts excluding 0.5 million shares
currently held by Kinross and shares that could be issued to Kinross upon the
conversion of the Debenture.
