Who We Are

DHT GeoSustainability Inc. is a specialized Canadian research and consulting company focused on sustainable mining, mine water management, environmental geochemistry, hydrogeology, and critical minerals development. The company helps mining, energy, government, and industrial clients understand and manage complex interactions between geology, water, mine waste, and the environment. DHT was established to provide rigorous, science-based solutions that support responsible resource development, regulatory confidence, and long-term environmental performance across the full mine life cycle, from exploration and project design to operations, closure, and post-closure stewardship.

Our consulting work integrates applied geochemistry, hydrogeochemistry, mineralogy, water quality assessment, acid rock drainage and metal leaching evaluation, contaminant transport, and predictive modelling. We support clients through technical studies, environmental assessments, permitting, mine waste characterization, water quality modelling, source term development, closure planning, and independent technical review. DHT also brings strong research capability in areas that are increasingly important to Canada’s resource economy, including critical minerals recovery from mine waste, bioleaching, biohydrometallurgy, mine waste valorization, carbon sequestration, enhanced rock weathering, and biotechnology-assisted water treatment.

DHT’s value lies in combining senior technical expertise with an innovation-driven consulting model. We translate complex scientific data into practical decisions for project owners, regulators, investors, and communities. Our goal is to help clients reduce environmental liabilities, unlock value from waste materials, improve water stewardship, and advance lower-impact mineral development. As demand grows for critical minerals, decarbonization, and responsible mining, DHT is positioned to deliver high-quality consulting services and applied research that support both commercial growth and measurable sustainability outcomes.
