Welcome to DHT GeoSustainability Inc.

Science-Driven Solutions for Sustainable Mining, Water, and Environmental Performance

At DHT GeoSustainability Inc., we help clients solve complex challenges across the mining, energy, chemical, water, and environmental sectors through practical, science-based solutions. In an industry shaped by rising environmental expectations, evolving regulations, and growing demand for critical minerals, DHT provides the technical leadership needed to move projects forward responsibly and confidently.

We are a trusted partner to mining companies, consulting firms, developers, investors, and regulatory stakeholders seeking high-value technical support in sustainable resource development. Our work is grounded in rigorous geoscience, engineering insight, and a clear commitment to environmental stewardship. We combine deep technical expertise with responsive client service to deliver solutions that are credible, innovative, and aligned with long-term project success.

Our mission is to deliver specialized, science-driven services that address the most pressing challenges in sustainable resource management, environmental performance, and decarbonization. We support projects across the mine life cycle, from early-stage evaluation and planning through operation, closure, and post-closure, with a focus on reducing risk, improving performance, and creating measurable environmental value.

Our Core Expertise

We fulfill critical needs across the mine, energy, chemical, and environmental sectors through seven strategic pillars.

Sustainable Mining and Critical Minerals

As global demand for critical minerals accelerates, DHT helps clients develop and optimize projects in a manner that is technically robust and environmentally responsible. We support sustainable extraction and recovery through advanced approaches such as bioleaching, biohydrometallurgy, geochemical characterization, and mineralogical assessment. Our expertise helps clients improve recovery, reduce environmental liabilities, strengthen permitting strategies, and support compliance throughout project development.

Decarbonization and Carbon Sequestration

DHT is advancing innovative pathways to help industry reduce emissions and contribute to climate goals. We support decarbonization strategies that transform mine wastes and industrial by-products into opportunities for long-term carbon management. Our work includes carbon sequestration in mine tailings, evaluation of mineral carbonation pathways, and the development of practical strategies that align environmental performance with circular economy principles.

Mine Life Cycle and Waste Management

We provide integrated technical support across all stages of the mine life cycle, helping clients make informed decisions from exploration and feasibility through operations, closure, and reclamation. Our services include mine waste characterization, tailings and waste rock assessment, life cycle assessment, closure planning, and long-term environmental performance evaluation. We focus on reducing uncertainty, managing geochemical risks, and supporting sustainable outcomes over the full project horizon.

Water Management and Hydrogeochemical Solutions

Water is one of the most critical aspects of responsible resource development. DHT provides specialized support in mine water quality, hydrogeochemistry, source control, predictive water quality assessment, and water management strategy development. We help clients understand water-rock interactions, assess potential impacts, manage operational risks, and support stewardship objectives through defensible technical analysis and practical mitigation approaches.

Environmental Assessment and Remediation

DHT supports environmental assessment, risk evaluation, and remediation planning with technically sound, data-driven solutions. We help clients identify environmental risks, assess potential project effects, support impact assessment processes, and develop remediation strategies for legacy and operational sites. Our approach is designed to protect ecosystems, satisfy regulatory expectations, and improve long-term environmental performance.

Mine Water Quality & Hydrogeochemical Modelling

DHT provides advanced mine water quality and hydrogeochemical modelling services to support technically defensible decision-making across the mine life cycle. We assess water-rock interactions, source loading, drainage chemistry evolution, and constituent fate and transport to predict water quality under baseline, operational, closure, and post-closure conditions. Our expertise includes conceptual site model development, predictive geochemical assessments, contaminant loading evaluations, and integrated modelling using industry-recognized tools such as PHREEQC, GoldSim, and related geochemical and water quality platforms. These services help clients reduce uncertainty, strengthen permitting submissions, and develop practical water management strategies grounded in sound science.

Hydrogeology & Groundwater Systems

DHT delivers specialized hydrogeological services to characterize groundwater systems, evaluate mine-related risks, and support sustainable water stewardship. Our experience includes hydrogeological investigations, groundwater flow interpretation, seepage assessments, contaminant migration analysis, pit and waste facility hydrogeology, and support for dewatering, closure, and long-term monitoring strategies. We integrate geological, hydrogeological, and geochemical data to develop robust conceptual and numerical understanding of site conditions. This enables clients to better manage water supply, protect receiving environments, and support regulatory compliance through reliable, site-specific groundwater assessments.

Permitting, Regulatory Review & Closure Strategy

DHT supports clients with strategic technical input for environmental assessment, permitting, regulatory review, and mine closure planning. We bring strong experience in reviewing EA and permitting documents, developing defensible technical submissions, and aligning project strategies with regulatory expectations and long-term environmental performance objectives. Our work bridges technical analysis with practical implementation, helping clients manage geochemical and water-related risks while improving project readiness, transparency, and regulatory confidence. From early project development to closure and post-closure planning, we help ensure that environmental commitments are credible, measurable, and achievable.
