Troilus Gold Corp. has reported a major milestone in the Company’s exploration and development plans with the start of dewatering at the J4 pit, a process that is expected to take approximately 6 months to complete.
Dewatering of the larger Z87 pit is expected to start in 2025 and will take approximately 18 months to complete. Dewatering of the Pits will provide safe access for ongoing exploration of the mined pits and is a key component to be completed for redevelopment of the existing mine site going forward.Justin Reid, CEO and Director of Troilus Gold, commented, “We are pleased to get started on this major milestone to upgrade the safety and access to the Pits at the Troilus site so that our team can gain a better understanding of the physical landscape and incorporate this knowledge in our exploration and development plans. Completing the Environmental Impact Assessment to dewater the pits and putting in place the equipment and infrastructure have demonstrated our team’s ability to manage the regulatory and stakeholder requirements to advance the complicated components of a mining project in Northern Quebec and provide valuable experience to continue moving the Troilus Project through the permitting process.”Three 140Hp pumps are currently operating at the J4 pit. The Troilus team has constructed new infrastructure around the pits to facilitate the dewatering including a main basin which will be used for the last 10 – 15% of the water to contain any sediment that may have settled at the lower levels of the Pits and a spillway to direct the water flow into the existing creek.Connection to the Hydro-Quebec grid with electricity generated from renewable hydroelectric sources ensures the Troilus team can maintain a consistent dewatering operation with a minimal carbon footprint. The water treatment facility has been upgraded to comply with government targets on water quality before release to the local environment. The water removed from the pits will be treated and carefully monitored for flow rate, pH level, and temperature at the point of effluence and further downstream to ensure the surrounding environment is not negatively affected. The Troilus environmental team will also conduct regular physical inspections to monitor erosion.In 2019, Troilus submitted an EIA to the Ministère de l’Environnement et de la Lutte contre les changements climatiques (“MELCC”) under Section 115.8 of the Environment Quality Act (Chapter Q02) requesting permission to dewater the Pits for exploration purposes, which was approved in 2020. Troilus also engaged in community consultations with Cree impacted families on the Troilus property and the local communities of Mistissini and Chibougamau to keep them informed of the dewatering proposal and integrate the feedback of stakeholders.
