Tundra is proposing a 2026/27 exploration program for the Property that is anticipated to run for 244 days beginning in March 2026 and ending in October (weather permitting). Similar field programs, including the same types of exploration activities, are expected to take place annually between March and October in subsequent years. Specific dates will be relayed to the CIRNAC engineer and any other necessary regulatory agencies. The proposed exploration program will include general exploration activities such as prospecting, geological mapping, geochemical sampling (rock, soil, till), drone photogrammetry, airborne or ground geophysics (IP, AMT), downhole geophysics, core drilling from up to 4 diamond drills, and RC drilling from up to 2 RC drill rigs. Drillhole depth is expected to average <400m with the total annual program expected to be less than approximately 25,000m. Drillhole locations are still to be determined, but locations will be submitted to the Nunavut Water Board (“NWB”) and Crown-Indigenous Relations and Northern Affairs Canada (“CIRNAC”) for approval prior to any ground disturbance. All planned drillhole pads will be inspected for the presence of archaeologically significant artifacts prior to commencement of drilling.The 2026/27 program will include the establishment of a seasonal 50-person camp at 526027 mE, 7478945 mN (the Hope Lake airstrip), including a storage facility and a fuel cache. Structures for the proposed camp will include 50 small individual (Arctic Oven) sleeper tents, or 16 canvas sleeper tents or similar, 4 kitchen tents/dry tents (with showers), 1 office tent, 6 core logging tents, a generator shack, a storage facility, a fuel cache, an incinerator, and outhouses/pacto system. Most of the structures will be Arctic Oven sleeper tents or canvas prospector tents, or similar, often with plywood floors.Three to five camp construction personnel will be on site for approximately 17 days (10 days for set up and 7 days for take down). Staff on site for the duration of the work program will consist of up to 8 to 12 geologists, 4 to 6 helicopter-company personnel, 1 to 2 cooks, 1 or 2 camp managers, and 26 to 28 drill-company personnel. Total amount of time spent on site will amount up to approximately 12,200 man-days per calendar year. This man-day estimate assumes full occupancy of the camp for 50 personnel for the entire 244 days of the planned exploration season.All waste, including organic and inorganic materials, will either be incinerated on-site in accordance with regulatory guidelines or transported to Kugluktuk, NU, or Yellowknife, NWT for proper disposal. Water is currently available on site; however, a water pump may be moved to a stream-fed lake 700m from camp to form the balance of water required for the expanded camp.The proposed work will be helicopter-supported and require the occasional landing of the aircraft. To mitigate any potential impact on wildlife, the helicopter will always maintain a minimum altitude of 610 m (2,100 ft) above ground level except during landing, take-off or if there is a specific requirement for low level flying (e.g. airborne surveys, drill rig moves, camp assembly). Wildlife will be avoided, and the helicopter will not land in the presence of wildlife except in an emergency. In addition, associated activities at the Property were previously screened by the Nunavut Impact Review Board (“NIRB”) (NIRB File No. 15EN009). Activities at the Property are currently authorized by CIRNAC Class A Land Use Permit (“LUP”) N2024C017 and NWB Water License (Type B) 2BE-COP1721. The current approved water usage authorized under the Water License (Type B) 2BE-COP1721 is 21m3/day for camp use. Tundra will apply to amend the NWB Water License (Type B) to allow for 299 m3/day for camp and drilling use, and will apply for a new CIRNAC Class A LUP for the proposed program.Please see attached Tundra Copper Coppermine River Property Non-Technical Summary - English 20251222 for the continuation of the non-technical project proposal for the Coppermine River Property.
