AGNICO EAGLE TO PURCHASE THE EXPLORATION ASSETS OF CANADIAN

MALARTIC CORPORATION; INCLUDING THE KIRKLAND LAKE AND HAMMOND

REEF GOLD PROJECTS

Toronto (December 21, 2017) – Agnico Eagle Mines Limited (NYSE:AEM, TSX:AEM)

("Agnico Eagle" or the "Company") today announced that it has agreed to acquire all of the

Canadian exploration assets of Canadian Malartic Corporation (" CMC"), including the

Kirkland Lake and Hammond Reef Gold projects (the "Transaction"). CMC is a corporation

50-50 owned and operated by Agnico Eagle and Yamana Gold Inc. (" Yamana"). The

Transaction is being structured as an asset deal, whereby Agnico Eagle will acquire all of

Yamana's indirect 50% interest in the Canadian exploration assets of CMC, giving Agnico

Eagle 100% ownership of CMC's int erest in the assets on closing of the Transaction. The

effective purchase price after the distribution of the sale proceeds by CMC to its

shareholders will be US$162.5 million in cash. The Transaction will not affect the Canadian

Malartic mine and related assets including Odyssey , East Malartic , Midway, and East

Amphi, which will continue to be jointly owned and operated by the Company and Yamana

through CMC and the Canadian Malartic General Partnership ("Canadian Malartic GP").

"The purchase of the CMC asset portfolio enhances our longer-term development pipeline,

and provides us with potential production growth post our current mine buildout in Nunavut”,

said Sean Boyd, Agnico Eagle's Chief Executive Officer. "The Kirkland Lake property

package enhances our current mineral reserves and offers near -term exploration upside,

while the Hammond Reef project provides good optionality to a potential rise in the gold

price”, added Mr. Boyd.

Under the proposed Transaction, Agnico Eagle wi ll acquire 100% of CMC's Canadian

exploration assets located in Ontario and Quebec, other than CMC's interests in Canadian

Malartic GP and the Canadian Malartic mine. CMC's principal Canadian exploration assets

include the Kirkland Lake and the Hammond Reef Gold projects, as well as additional mining

claims and assets located in Ontario and Quebec. The Kirkland Lake project covers

approximately 27,291 hectares in northeastern Ontario and mineral reserves and mineral

resources have been outlined on several properties. Key deposits in the Kirkland Lake area

include: Upper Beaver, Anoki and McBean, Amalgamated Kirkland (AK) and Upper Canada.

Hammond Reef is an advanced stage gold project covering approximately 31,145 hectares

in northwestern Ontario. The project contains well defined mineral resources.

The mineral reserve and mineral resource estimates in this table represent the 50% portion

being acquired by Agnico Eagle. CMC owns and manages the Upper Beaver, AK and

Anoki/McBean projects in Kirkland Lake, northeastern Ontario, and the Hammond Reef

project in northwest Ontario. The mineral reserve estimate for the Upper Beaver project as

of December 31, 2016 used the following assumptions: US$1,200 per ounce gold; US$2.75

per pound copper; a foreign exchange rate of C$1.25 per US$1.00; and a C$125/tonne net

smelter return (NSR) cut -off value. The mineral resource estimates for the Upper Beaver

project used an NSR cut -off of C$95/tonne, which represents approximately 75% of the

mineral reserve cut -off value. The mineral resource estimate for the AK project used the

following assumptions: US$1,200 per ounce of gold; operating cost of US$80 to

US$100/tonne; and a cut -off grade of 2.5 g/t gold. The mineral resource estimate for the

Anoki/McBean project used the following assumptions: US$1,200 per ounce of gold;

operating cost of US$120/tonne; and a cut -off grade of 2.5 g/t gold. The mineral resource

estimate for the Hammond Reef project used the following assumptions: US$1,400 per

ounce of gold; operating cost of US$11.27/tonne; and a cut-off grade of 0.32 g/t gold for the

West Pit, and 0.34 g/t gold for the East Pit.

Notes to US Investors Regarding Mineral Reporting Standards

Each of Agnico Eagle and CMC prepare their mineral reserve and mineral resource

estimates in accordance with the requirements of securities laws in effect in Canada, which

differ from the requirements of US securities laws. Terms relating to mineral resources and

mineral reserves in this news release are defined in accordance with NI 43-101 under the

guidelines set out in the Canadian Institute of Mining, Metallurgy, and Petroleum Standards

on Mineral Resources and Mineral Reserves. For United States reporting purposes , the

SEC applies different standards in order to classify mineralization as a reserve. As a result,

the definitions of proven and probable reserves used in NI 43-101 differ from the definitions

in the SEC Industry Guide 7. In addition, the SEC does not recognize the terms "measured

resources", "indicated resources" and "inferred resources". Investors are advised that while

those terms are recognized and required by Canadian regulations, the SEC does not

recognize them. Investors are cautioned not to assume that any part or all of mineral

deposits in these categories will ever be converted into mineral reserves . "Inferred mineral

resources" have a great amount of uncertainty as to their existence, and great uncertainty

as to their economic and legal feasibility. It cannot be assumed that all or any part o f an

inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules,

estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility

studies, except in rare cases. Investors are cautioned not to assume that any part or all of

an inferred mineral resource exists, or is economically or legally mineable.
