Teck and Agnico Eagle Announce Completion

of the San Nicolás Copper-Zinc Project Joint Venture

Vancouver, B.C. and Toronto, ON – Agnico Eagle Mines Limited (TSX and NYSE: AEM) (“Agnico Eagle”)

and Teck Resources Limited (TSX: TECK.A and TECK.B, NYSE: TECK) (“Teck”) announced today that

the previously announced joint venture transaction between Teck and Agnico Eagle to advance the San

Nicolás copper -zinc development project has closed. Teck and Agnico Eagle have entered into a joint

venture shareholders agreement whereby Agnico Eagle, through a wholly -owned Mexican subsidiary, has

agreed to subscribe for a 50% interest in Minas de S an Nicolás, S.A.P.I. de C.V. (“MSN”) for US$580

million, to be contributed as study and development costs are incurred by MSN. For governance purposes,

Agnico Eagle is deemed to be a 50% shareholder of MSN from closing, regardless of the number of shares

that have been issued to Agnico Eagle or its subsidiary.

Teck and Agnico Eagle are now 50/50 joint venture partners at San Nicolás , working together to advance

permitting and development of the high- quality co pper-zinc San Nicolás project located in Zacatecas,

Mexico. The joint venture partners are planning to submit an Environmental Impact Assessment and Permit

application for San Nicolás in the first half of 2023 and are targeting completion of a feasibility study in early

2024. Concluding the San Nicolás joint venture, initiating permitting, and completing the next stage of

technical studies, is another positive step in Teck’s strategy to advance its industry leading Copper Growth

portfolio in a timely and prudent manner and for Agnico Eagle in lev eraging its Mexican operating

experience and know -how to pursue growth in a high- quality, copper -zinc mineral deposit located in a

premier mining jurisdiction in Mexico.
