The Somerset Trough Project (“Project”) is an early exploration program located on Somerset Island. The project area consists of contiguous mineral claims extending across both the Qikiqtani and Kitikmeot regions of Nunavut. Project activities for the year 2025 will consist of the construction of an exploration camp, airborne and ground-based geophysical surveys, geological studies (prospecting and mapping), and minor environmental and wildlife studies. These activities have previously been screened and approved by the Nunavut Impact Review Board (NIRB File #: 24EN005, NPC File #: 150217) with applicable Terms and Conditions. The Project has obtained a Class A Land Use Permit from Crown Indigenous and Northern Affairs Canada (CIRNAC) that covers the previously approved activities (CIRNAC LUP: N2024C0005).This application covers an amendment to the previously approved activities including the addition of drilling for future years beyond 2025 and associated increases in water usage and hazardous waste generation (through drilling activities). These exploration programs in years 2026 and beyond are anticipated to consist of advancing up to 45,000 metres of drilling annually using diamond drills and/or reverse circulation drills to retrieve drill core and rock chip samples that will be logged and sent for laboratory analysis. In line with Bronzite’s previous NIRB application, the 2025 exploration program will consist of the construction of an approximately 20-person exploration camp in the spring and/or early summer. The initial spring camp will consist of temporary structures placed on top of the snow and ice cover without disturbing the ground underneath. Prior to snow melt and commencement of summer activities, the temporary structures will be removed to permit the completion of an archaeological survey over the camp area. After completion of the archaeological survey, the constructed camp will consist of a series of weatherhavens for accommodation, dining, camp drys, storage, sample processing, and first aid, along with a small generator building. Camp buildings will be heated with diesel heaters complete with spill protection. Camp infrastructure and machinery such as snowmobiles and all-terrain vehicles (ATV) will be mobilized to site using either a Basler DC-3 or Twin Otter aircraft on skis/tundra tires, depending on ground conditions. The camp is expected to remain on the land for the duration of the exploration program. As per the Territorial Land Use Regulations, Bronzite will seek written approval from the Crown Indigenous and Northern Affairs Canada engineer to leave the camp largely intact in the off-season until crews return the following year.Minimal water will be used for the 2025 exploration program, and only an NWB Authorization will be required. Surface water will be collected from a nearby water body with a pump or portable containers and used for cooking, drinking, and washing in camp. It is anticipated that a maximum of 10 m3 of potable water will be used each day to accommodate the staff members. Greywater will be deposited to a sump located more than 31 m from the ordinary high-water mark of any body of water. Human waste will be collected using Pacto toilets and the waste will be incinerated daily along with domestic waste. In years 2026 and beyond, Bronzite will use less than 299 m3 of water per day to support camp and drill operations, which will require a Class B Water License. Exploration activities in 2026 and onward will be a combination of field based geological and geophysical studies along with diamond and/or reverse circulation drilling. Drills will be mobilized and removed using helicopters and will require minimal to no ground clearing for drill pad construction. Lumber will be utilized, where required, to elevate the drill off the ground to minimize disturbance. Drill sites will avoid environmentally or culturally sensitive areas. No prohibited chemicals will be used in drilling operations and drill cuttings and return water will be deposited into a sump at each drill site. Appropriate water management methods will be used to ensure that drill cuttings and water are contained and do not impact adjacent land and water bodies. After completing drilling at each site, the work area will be cleared of all solid waste and other materials such as fuel drums, and these materials will be transported back to camp for safe temporary storage. Drill collars will be removed, where possible, or otherwise cut flush with the ground surface. All drill sites will be left in clean and stable conditions and will be inspected by the Project Manager and photographed prior to demobilisation.
