Hyaltus has a proven track record of supporting the mining and energy sectors with sustainable, science-based analyses that inform environmental assessments and advance project approvals. We specialize in the use of integrated surface water–groundwater models to evaluate hydrologic impacts, guide mitigation strategies, and support the permitting of both open-pit and underground mine expansions.

We support projects across the mine lifecycle - from baseline studies and expansion planning to long-term water management and closure planning. Our numerical models are built as flexible decision-support tools, enabling scenario testing to evaluate mine development alternatives, climate variability, and mitigation options over time.

Our services include:

• Integrated water balance modelling using coupled surface water–groundwater frameworks to support permitting and site-wide water management.

• Permitting support for mine expansions, closure planning, water takings, and dewatering plans.

• Assessment of hydrologic impacts from mine development, including cumulative effects on environmental flow needs, groundwater–surface water connectivity, and competing water users.

• Evaluation of climate change impacts on operational water management plans and downstream flow regimes.

• Technical support for engagement with regulators, communities, and stakeholders.

We have experience working with mines, quarry and aggregate operations, and oil sands developments, providing support both directly to operators and as independent technical peer reviewers in regulatory processes.
