Our Planet

At Tahoe, we understand that practicing strong environmental stewardship is integral to ensuring the long-term viability of our communities, our business, and our planet.

Water:

Water is as important to the local areas where we operate as it is to our operations. Our goal to protect existing water sources is achieved by conserving and recycling water used in the mining process and through extensive water management and treatment programs and strategies. Tahoe uses ground water and surface water for mining and milling, or heap leach processes at our various operations. We design our mine operations to minimize fresh water use and maximize water reuse through use of rainwater catchment and storage ponds, mine dewatering processes and recycled process water. Each operation implements site-specific water quality monitoring processes to meet water conservation and quality objectives. These efforts safeguard against adverse impacts on water quantity and quality in our local communities.

Waste Management:

Tahoe is committed to the responsible management of effluents and waste generated from our operations. The byproducts generated at our operations consist primarily of waste rock, tailings, and mine process effluents. We manage our waste through coordinated efforts across all of Tahoe’s operations: Our environmental staff works closely with mining and processing departments to monitor compliance, with oversight provided by senior management at each operation. We dedicate a significant amount of resources to minimize waste production and eliminate impacts to air, water and soil resulting from waste storage. We align our policies and practices with international guidelines, and meet or exceed local government regulations in every jurisdiction.

Waste Management

Once it meets all regulatory water quality standards, mine effluent from the Timmins West complex is discharged to the Tatachikapika River, which is subject to an extensive monitoring program.

Land Use:

Tahoe strives to responsibly develop, operate and close our operations in ways that generate social and environmental benefits to stakeholders. We recognize that the eventual closure of operations can have significant social, economic, and environmental impacts and require proper mitigation of environmental impacts, as well as managing and addressing stakeholders’ social and economic concerns. A key element to Tahoe’s land use strategy is utilizing the ‘mining for closure’ concept at all operations, incorporating the long term final closure and cost requirements into the design, construction, and operation of the mine. This includes working cooperatively with local and regional community members, regulatory authorities, local municipalities, NGOs and educational partners to develop and implement land use measures to ensure that post mining land use meets stakeholder needs and expectations.

Biodiversity:

Effective biodiversity management and protection is a fundamental aspect of Tahoe’s environmental strategy and key to minimizing impact to the areas surrounding our operations. Although none of Tahoe’s operations are in protected or high-biodiversity value areas, each operation complies with extensive biodiversity commitments as laid out by regulators, communities and stakeholders during environmental impact analysis. These include mitigation and management plans for alteration of vegetation cover, impact to native species and aquatic habitats, alteration and changes in patterns of abundance and distribution of fauna habitats, and impact to fragile ecosystems and ecosystem services. Tahoe recognizes that biodiversity is critical to an ecosystem and its productivity. We strive to work with our local communities and other stakeholders to operate and close our operations in a manner that maintains or enhances these valuable resources.

Biodiversity

The frog species Ptychohyla euthysanota is commonly found in the area surrounding the Escobal mine site. Since 2015, Minera San Rafael has been monitoring the species and maximizing protection efforts through habitat enhancement and reforestation.

Closure:

Closure planning is a key aspect to minimizing long-term environmental impacts and maximizing long-term benefits. Tahoe’s “mining for closure” concept ensures that each of our operations has an extensive closure plan in place, covering all aspects of decommissioning, reclamation and post-closure monitoring with a commitment to rehabilitate and restore the area once the mine is closed. Our reclamation and closure plans include measures for managing surface disturbance, remediation of impacted areas, structure removal, earthwork, and seeding and fertilizing, with consideration of community needs related to all closure activities. We review our closure plans and costs on an annual basis to ensure they meet the evolving nature of the operations for the life of the mine.
