SUMMARY OF SOLVED TECHNICAL COMMENTS TERRESTRIAL Technical comment subject # Item Theme 1. Terrestrial BLHTO-1 Caribou: Possible change in caribou migration/distribution since the development of the Meadowbank project 2. Terrestrial BLHTO-2 Caribou: Reduced activity at the mine site or access roads in response to caribou Presence. 3. Terrestrial BLHTO-3 Dust: Agnico Eagle’s approach to dust control 4. Terrestrial BLHTO-4 Caribou: Agnico Eagle’s approach to blasting when Caribou are nearby 5. Terrestrial BLHTO-6 Compliance of terms/conditions in project certificate or land use permits 6. Terrestrial ECCC-TC 11 Assessment of Direct Habitat Loss and Destruction of Nests. Provide revised assessment of displacement of migratory birds for the proposed Expansion Project footprint and for the flood zone. ECCC-TC 12 Migratory Bird Protection Plan - Update the Migratory Bird Protection Plan - Include monitoring for the extent and timing of flooding in the Migratory Bird Protection Plan to validate the FEIS Addendum predictions derived from hydrological models. 7.

SUMMARY OF SOLVED TECHNICAL COMMENTS TERRESTRIAL Item Theme Technical comment # 8. Terrestrial ECCC-TC 14 Mortality of Diving Waterbirds ‐ Fishouts. Deferring revisions required to update the Fish ‐out Diving Waterbirds Protection Plan be to the regulatory phase is a reasonable approach. GN-TRC-#01 1. GN and other intervenors should be afforded an opportunity to submit technical comments relating to asbuilt report for the existing haul road. 2. Provide estimates for the proportion of the existing Haul Road that has: (a) Side slopes of 4: 1 or gentler; (b) Side slopes top dressed with 0 -40 mm; and (c) A height of 0 -1 m, 1 -2 m, 2 -3 m and greater than 3 m. 3. Provide estimates for the proportion of the proposed Haul Road that has: (a) Side slopes of 4: 1 or gentler; (b) Side slopes top dressed with 0 -40 mm; and (c) A height of 0 -1 m, 1 -2 m, 2 -3 m and greater than 3 m. 4. Clarify whether the side slopes of the proposed Haul Road will be constructed with a slope of 4: 1 (or gentler) along most of road’s length or at specific caribou crossing location. 51. . Clarify whether the side slopes of the proposed Haul Road will be top dressed with 0 -40 mm along most of road’s length or at specific caribou crossing location. 6. Clarify how many wildlife crossing structures are currently in place along the existing Haul Road. 7. Clarify how many wildlife (caribou) crossing structures are proposed for the proposed wider Haul Road. GN-TRC-#05 1. Revise the assessment to include a range of alternatives that differ with respect to rate of mining and/or Haul Road traffic. 2. Revise the assessment to include a range of alternatives involving seasonal variation in use of the Haul Road in-order to reduce traffic levels during caribou migratory periods and increase them outside these sensitive periods. 9. 10.

SUMMARY OF SOLVED TECHNICAL COMMENTS TERRESTRIAL Item Theme Technical comment # Technical comment subject 11. Terrestrial Kiv. IA-Terrestiral-02 Conduct an analysis of annual collar movements relative to traffic frequency, and road structure for AWAR and the newly constructed Whale Tail haul road to describe caribou movement rates. 12. Terrestrial Kiv. IA-Terrestiral-04 Develop mitigation for caribou specific to widening of the haul road: 1) Widening of the haul road should avoid when caribou are migrating through the RSA. 2) Road widening construction is halted when the first caribou are approaching. Clarify how the threshold of 500 m for triggering Level 2 monitoring/mitigation of muskoxen was established, and how the NPC-119 guideline was used to inform the threshold determination. 13. Terrestrial 14. Terrestrial NIRB-TC-06 Clarify under what conditions additional mitigation would be initiated when Level 2 threshold is triggered. NIRB-TC-10 How it has quantified the zone of influence for project components on caribou movement? Agnico Eagle | WHALE TAIL PIT EXPANSION PROJECT NIRB TECHNICAL MEETING – JUNE 11 -13 2019 8

SUMMARY OF TECHNICAL COMMENTS SOLVED WITH COMMITMENTS - TERRESTRIAL Item 1. Theme Terrestrial Technical comment # Technical comment subject Agnico Eagle Comments /Rationale/ Response GN-TRC-#02 Haul Road Snow Management Agnico Eagle agrees to monitor snow berm height and depth of snow along the sides of the Haul Road in representative areas. Data gathered will be used to assess if additional studies/monitoring is required. This information will be shared with the Terrestrial Advisory Group. Timeline: To be determined A monitoring plan for the haul road will be developed for the Expansion Project and will be discussed with, and consider input, by the Terrestrial Advisory Group Timeline: To be determined 2. Terrestrial GN-TRC-#03 Roads as Barriers to Caribou 3. Terrestrial GN-TRC-#04 Road Closures Agnico Eagle agrees and will provide a daily updates to Terrestrial Advisory Group members when roads are closed. Timeline: As required Terrestrial GN-TRC-#06 (Parts 1, 2) Caribou Monitoring and Mitigation The final Terrestrial Ecosystem Management Plan Version 7 will be submitted to the Nunavut Impact Review Board mid-June, 2019, and will include the commitments table presented in Appendix B. Timeline: Mid-June, 2019 4. Agnico Eagle | WHALE TAIL PIT EXPANSION PROJECT NIRB TECHNICAL MEETING – JUNE 11 -13 2019 10

SUMMARY OF UNRESOLVED TECHNICAL COMMENTS TERRESTRIAL Item Theme Technical comment # Technical comment subject Agnico Eagle Comments /Rationale/ Response Currently Agnico Eagle does not have monitoring designed to evaluate this request, however, monitoring caribou interactions with the road will be completed and will consider several variables in addition to road design. Further discussion is required Further discussions are required regarding how Kivalliq Inuit Association suggestions can be implemented 1. Terrestrial Kiv. IATerrestiral-01 (Part 3) Uncertainty in caribou responses to slope edges of the upgraded Whale Tail haul road Part 3) Agnico Eagle should undertake an analysis of the existing data on caribou crossings for the AWAR and Whale Tail haul road designs to determine the effects of slope relative to height of the road above the surround terrain and the slope’s granular material. 2. Terrestrial Kiv. IATerrestiral-03 (Part 2) Disturbance to caribou during haul road widening (lead caribou) - Agnico Eagle | WHALE TAIL PIT EXPANSION PROJECT NIRB TECHNICAL MEETING – JUNE 11 -13 2019 12
