Dayton Mining Corporation (DAY: TSE, AMEX) Kinross Gold Corporation (K: TSE, KGC: NYSE)

Mirage Resource Corporation (MGP: TSE)

C$21 MILLION PURCHASE OF ASSETS BY DAYTON INVESTMENT BY KINROSS GOLD

Bill Myckatyn, President and CEO of Dayton Mining Corporation announces that Dayton has entered

into agreements to acquire a 49% interest in the Denton-Rawhide Mine in Fallon, Nevada and to

acquire 100% of Mirage Resource Corporation of Vancouver, British Columbia.

Dayton has entered into a letter of intent with Kinross Gold Corporation to purchase its 49% interest in

the Denton-Rawhide Mine for a total of 144,710,000 Dayton common shares.

Dayton has entered into a letter of intent with Mirage under which Dayton will acquire all of the

common shares of Mirage pursuant to an amalgamation between Mirage and a wholly-owned

subsidiary of Dayton. Each Mirage common share will be exchanged for 0.667 of a Dayton common

share. This exchange ratio represents a purchase price of $0.075 per Mirage common share which is a

14% premium to the price of Mirage common shares based upon a 30 day average trading price of

$0.066 for the Mirage common shares and $0.113 for the Dayton common shares.

Kinross holds approximately 14 million Mirage common shares representing a 53.8% interest. Dayton

has entered into a letter of intent with Kinross under which Kinross has agreed to vote its Mirage

common shares in favour of the amalgamation. In the event the amalgamation is not approved by a

special resolution of shareholders of Mirage, Dayton has agreed to purchase Kinross’ Mirage common

shares at the lesser of $0.075 and 115% of the market price of the Mirage shares. This purchase price

will be paid in common shares of Dayton. In addition, in the event the amalgamation is completed or

Dayton acquires the common shares of Mirage held by Kinross, Dayton has agreed to acquire from

Kinross all shareholder loans made by Kinross to Mirage in exchange for common shares of Dayton.

Based upon shareholder loans estimated at closing, this will result in Dayton issuing to Kinross a total

of approximately 24.3 million common shares of Dayton. This acquisition of Mirage's debt and equity

will result in the issuance of a total of approximately 42 million Dayton common shares.

The combined transactions, based on the 30 day average trading prices of Dayton and Mirage, are

valued at approximately C$21 million. Upon closing of the transactions, Dayton will have approximately

538 million shares outstanding. Dayton will issue approximately 178 million common shares to Kinross

which will result in Kinross owning 33% of the equity of Dayton. Dayton is proposing that a share

consolidation of 20:1 be effected upon closing of the transactions, subject to applicable shareholder

and regulatory approval.

Upon closing of the transaction, Dayton Mining will have:

q

A diversified production base from interests in the Denton-Rawhide gold-silver mine in Nevada

and Dayton's 100% owned and operated Andacollo Gold Mine in Chile;



q

Increased cash flow from estimated proforma annual production in 2000 of approximately

170,000 ounces of gold equivalent from the Andacollo Gold Mine and the Denton-Rawhide gold-

silver mine (49%) with a combined average cash cost of US$230 per gold equivalent ounce;

Total mineable reserves of 33.4 million tonnes grading an average of 0.798 grams of gold per

tonne and 5.46 grams of silver per tonne or approximately 953,000 ounces of gold equivalent;

and

Near-term potential development of Mirage’s El Dorado project in El Salvador plus grassroots

exploration upside at the Denton-Rawhide mine.

q

q

In addition, Bob Buchan, Chairman and CEO of Kinross and John Ivany, President and CEO of Mirage

and Executive Vice President of Kinross, will join Dayton's board of directors, bringing the total to eight.

Bill Myckatyn, Chairman, President and CEO of Dayton stated “Dayton's objective is to become a

400,000 ounce gold producer within three years. The proposed acquisition of the 49% interest in the

Denton-Rawhide mine and the proposed acquisition of Mirage Resources Corporation provide Dayton

with a solid platform for growth from which to acquire further gold producing assets to achieve that

goal and build a strong mid-cap gold company.”

Bob Buchan, Chairman and CEO of Kinross Gold Corporation commented, “We have made an

investment in a management team that has demonstrated an ability to successfully develop and

operate gold projects. We are pleased to be associated with Dayton and intend to be a long-term

sponsor to Dayton providing capital support for the acquisition of new projects and the development of

new properties as required.”

John Ivany, President and CEO of Mirage Resources said, “Dayton’s offer provides Mirage with the

opportunity to advance the development of the company’s primary asset, the El Dorado property, with

greater certainty.”

The Denton-Rawhide mine is an open-pit, gold-silver heap leach operation located near Fallon, Nevada.

Kennecott Minerals Company is the operator of the mine owning 51%. Gold production in 1999 was

approximately 128,000 gold equivalent ounces (100%) at a cash cost of approximately US$243 per

gold equivalent ounce.

At December 31, 1999, the reported reserves (100%) at the Denton-Rawhide mine were 31.9 million

metric tonnes grading 0.705 gpt gold and 11.68 gpt silver. These reserves were estimated using a gold

price of US$325 per ounce. Exploration potential in the vicinity of the mine site has not been fully

tested to date.

The primary asset of Mirage Resources is the El Dorado gold property located near San Salvador, El

Salvador. The property is a high-grade banded quartz system. More than 42,000 metres have been

drilled on the property since 1993. Geological resources of 4.2 million metric tonnes grading 6.64 g/t

gold and 48.4 g/t silver have been delineated by Mirage which includes 1.3 million metric tonnes

grading 11 g/t gold and 74.6 g/t silver. This total reported resource represents 892,000 ounces of

contained gold and 6.5 million ounces of contained silver. Dayton plans to begin a feasibility study on

the property this year.

The completion of the Mirage amalgamation is conditional upon satisfaction of a number of conditions

including agreement being reached on definitive agreements, receipt by an independent committee of

the board of directors of Mirage of a satisfactory fairness opinion, receipt by the board of directors of

Dayton of a satisfactory fairness opinion, approval of the amalgamation by a special resolution of

Mirage shareholders, approval of the amalgamation by the Supreme Court of British Columbia,

approval of the issuance of shares by Dayton by an ordinary resolution of Dayton shareholders,

approval of the proposed 20:1 share consolidation by a special resolution of Dayton shareholders,



completion of the acquisition by Dayton of a 49% interest in the Denton-Rawhide mine and receipt of

all applicable regulatory approvals. The completion of the Denton-Rawhide acquisition is also subject to

satisfaction of a number of conditions including agreement being reached on definitive agreements,

approval of the issuance of Dayton shares by an ordinary resolution of Dayton shareholders, approval

of the proposed 20:1 share consolidation by a special resolution of Dayton shareholders, and receipt of

all applicable regulatory approvals. Each of Dayton and Mirage anticipate holding an extraordinary

general meeting of shareholders on or about March 29, 2000 to consider the foregoing matters. Closing

is anticipated to occur on or about April 6, 2000.

Further detailed information regarding the assets to be acquired by Dayton will be included in

subsequent shareholder material.

Andacollo Reserve Update

Dayton announces that the mineable reserve estimate at US$325 per ounce for the Andacollo Gold

Mine in Chile was audited by the Winters Company of Tucson, Arizona and is as follows:

Reserves (at US$325):

Year

31 Dec 1999

Tonnes (000’s)

17,797

Grade (G/T)

0.88

Contained Ounces

502,000

Strip Ratio

1.79

The reduction in mineable reserves compared to year end 1998 is due to additional drill information,

the implementation of new modeling methodology, and the mining of 189,000 ounces in 1999.

The reserves for the Tres Perlas deposit, which has not been mined since 1997, were re-modeled at

year end 1999. A more conservative modeling technique was used. This resulted in a decrease of

reserve ounces and fewer production ounces in the final year of operation from this deposit. Production

and cost estimates at Andacollo for 2000 and 2001 are not affected by the reduction in reserve ounces

at Tres Perlas.

Dayton has budgeted approximately US$800,000 for exploration drilling in 2000. Four target areas

have been identified which consist of infill, step out and exploration drilling. Dayton has also been

having discussions with regard to acquiring small land packages near its mine site.

Production estimate for the Andacollo Gold Mine in 2000 is 125,000 ounces of gold at cash operating

costs of US$229 per ounce.
