The Hamlet of Gjoa Haven (Hamlet) is proposing to construct and operate up to four new quarry sites (GH-105, GH-106, GH-107, and 2N) to replace the Hamlet’s currently operating quarries, which will become depleted in the next operating year. These new quarries contain sand, silt, and gravel which will serve the current and future aggregate needs of the Hamlet, such as road construction and maintenance. Quarry operation will occur on an as-needed basis, planned to begin in 2026, depending on project development, progress, and municipal need. Field assessments were conducted in 2024 and 2025 to support the proposed quarry development and application for a Quarry Permit. Geotechnical investigations carried out in 2024 focused on evaluating the potential sites for terrain conditions, dimensions and quality of the deposits. Geochemical testing was completed in 2025 to assess for acid rock drainage (ARD) and metal leaching (ML) potential. The results of the field studies will inform the Borrow/Quarry Management Plans and associated mitigation measures. Archaeological assessments were completed in both 2024 and 2025 to evaluate the quarry sites for archaeological significance and to designate high-sensitivity areas, where appropriate. The four proposed quarries are located in and around the Hamlet. Two of the four quarries, GH-105 and GH-106, are located on Crown land (federal). Quarry 2N is located within the municipal boundary of the Hamlet on Government of Nunavut Commissioners land. Quarry GH-107 is located partially within the Hamlet on Commissioners land, and partially on Crown land (see Figure 1). The proposed quarries can be accessed by municipal roads, which may require future upgrades. Equipment will be used for excavating material, crushing and sorting aggregate, and stockpiling and hauling material. Fuel is not anticipated to be stored at the quarries, and equipment will be properly cleaned and fueled prior to being operated. Accidental spills that may occur during quarry operation will be managed through the Spill Contingency Plan (Attachment 1). Water usage on site will be managed in accordance with the Hamlet’s existing Water License (No. 3BM-GJO1828). Water usage is anticipated for dust control and will require approximately 5 cubic metres (m3)per day of operation. Water will be trucked from the approved water source, Swan Lake, to the quarry site and used on an as-needed basis. At the quarry locations, an intermodal container may be used for storage and transportation of equipment, as needed. One portable office trailer may also be used at active quarries. The portal office will include a bathroom for personnel, of which any wastewater produced will be trucked to the sewage lagoon for approved disposal. Waste from the quarries will be disposed of at the Gjoa Haven Solid Waste Disposal Facility.The quantity and type of aggregate anticipated to be extracted varies by quarry. Quarry GH-105 has an estimated 140,000 m3 of sandy gravel and cobbles, Quarry GH-106 is estimated to have 100,000 m3 of sand and gravel, Quarry 2N is estimated to have 250,000 m3 of sand, gravel, and cobbles, and Quarry GH-107 has an estimated 43,000 m3 of sand, gravelly sand, and gravel.Quarries are anticipated begin operation in 2026 on an as-needed basis until 2031 where the quarries will be depleted and undergo closure.
