Professional, scientific, technical, and contracting services for Sustainable Mining and Critical Minerals.
We help mining companies, engineering firms, and regulators reduce environmental risk, improve water and waste management, and advance projects with confidence.
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.
We fulfill critical needs across the mine, energy, chemical, and environmental sectors through seven strategic pillars.
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 provide senior technical advisory integrating hydrogeochemistry and water balance across the full mine life cycle to translate uncertainty into defensible management strategies.
Evaluating the geochemical evolution of mine-affected waters through hydrochemical analysis to distinguish natural backgrounds from mine-influenced signatures.
Applying advanced mineralogical techniques (XRD, SEM-EDS) to define source controls governing drainage chemistry and improve water quality prediction.
Designing and interpreting static, kinetic, and field-scale testing programs to classify materials and identify critical long-term leaching behaviors.
DHT supports developing practical source-control strategies—including material segregation, blending, and encapsulation - to reduce long-term water treatment liabilities.
We are experts translating laboratory, field, and analogue data into defensible, model-ready solute release rates to bridge characterization and closure predictions.
Developing, updating and reviewing dynamic GoldSim water balance and water quality models to support infrastructure sizing, discharge permitting, and long-term liability evaluation.
Utilizing PHREEQC to evaluate aqueous speciation, mineral saturation, and complex treatment chemistry to improve the scientific basis of predictions.
