Agnico Eagle currently places all tailings at the Meadowbank Mine in the Meadowbank Tailings Storage Facility (within the former Second Portage Lake northwest dewatered arm), where tailings have been deposited sub-aerially as slurry and water from the ponds reclaimed during operation. Since mining began, Agnico Eagle has continued to evaluate alternative options for tailings deposition, in order to ensure that best practices are followed and to ensure appropriate long term planning to optimize the site footprint. In 2016, the Meadowbank Dike Review Board (the MDRB), an Independent Geotechnical Expert Review Panel established in accordance with Type A Water Licence No: 2AM-MEA1525, supported the use of early in-pit tailings disposal as an appropriate alternative in addition to current practices at Meadowbank Mine. Specifically, in-pit disposal of tailings has advantages with respect to health and safety, quality of life, water, air, capital cost, technology, natural hazards and adaptability. The MDRB accepted that in-pit disposal would be recognized as the best available technology. As a result, Agnico Eagle is now proposing to dispose of tailings in three pits, Portage Pit A, Portage Pit E, and Goose Pit, all within the footprint of the assessed and approved Meadowbank Mine. The In-pit tailings disposal in the Portage and Goose pits will not increase the project footprint, and will occur entirely within existing pits that have already been impacted by ore extraction. This method of tailings disposal will require the continued use of various existing project components, including the following: •pits and dikes to segregate operations from Third Portage Lake and Second Portage Lake; •the reclaim water barge; •the tailings deposition barge; •the reclaim water treatment plant; and •tailings thickener (this is under evaluation). The modification will also require an extension of the slurry and reclaim water piping. Agnico Eagle confirms that based on its engagements to date, its understanding is that this modification can proceed in accordance with existing approvals. Agnico Eagle has not identified any amendments to Project Certificate No. 4 or Type A Water Licence No. 2AM-MEA1525 in order to proceed with the In-pit Tailings Disposal modification. Before proceeding, the In-pit Tailings Disposal modification will require a formal Modification notification to the Nunavut Water Board pursuant to the conditions of the water licence. The current planned timeline for commencing the in-pit deposition of tailings is April 2018. Agnico Eagle is committed to proceed with this activity in full compliance with its regulatory obligations and with the obligations and guidance set out in the Keewatin Regional Land Use Plan. Agnico Eagle's self assessment is that the proposed In-Pit Tailings Disposal modification is not a significant modification under NuPPAA, in particular when taking into account the s. 90 factors. The modification is located within the area of impact previously assessed, with no additional historical, cultural and archaeological significance. Agnico Eagle considers the nature, magnitude, complexity, probability, frequency, reversibility and cumulative impacts are unaffected as outlined in Cumberland (2005) , which previously conformed with the applicable land use plan as determined by NPC and was reviewed by the NIRB.

There is currently a tank farm enclosing a 5.6 ML fuel tank on‐site at the Meadowbank Mine, which has been in service since 2009. Agnico Eagle is proposing to install a new 3.3 ML tank next to the existing tank and modifying the secondary containment area so that the two tanks will share the new containment space. The additional fuel tank will provide flexibility to the Mine during the caribou migration when the All‐weather Access Road is closed, and would result in fewer fuel convoys during the caribou migration.
