About

Knight Piésold's mining expertise has been applied to hundreds of surface and underground mining projects worldwide, under a wide range of biophysical conditions. We provide comprehensive multidisciplinary services through all stages of mine development, from evaluation and permitting to construction and closure.

Our professionals work seamlessly together to build value for your project. We complete successful stakeholder engagement, environmental studies, and government liaison services built on innovative and cost-effective engineering solutions.

By providing quality and environmentally sound engineering and science, our clients in the international mining industry trust Knight Piésold to successfully move their projects forward through to completion. We work with the client team to identify and reduce risk throughout the project lifecycle. Knight Piésold adds value to projects through engineering to the highest environmental standard, conducting effective engagement of communities, aboriginals, and governments, and ensuring compliance with lending institutions. This approach increases efficiency, return on investment, and the reputational advantage of our clients’ projects.

Our mining expertise includes the following:

  • Public and aboriginal engagement
  • Environmental baseline studies
  • Environmental impact assessment
  • Government liaison, legislation, and permitting
  • Geotechnical engineering
  • Tailings management
  • Waste characterization
  • Pipelines and pump stations
  • Heap leach pad design
  • Open pit and underground rock mechanics
  • Waste and water management
  • Mine closure and reclamation
  • Renewable energy schemes and energy optimization planning

From site assessment through to construction supervision and QA/QC, we have extensive experience in the full spectrum of geotechnical services for mining projects. Geotechnical conditions of each project site are unique and our approach is to tailor the investigations to the degree of complexity of the site and provide an appropriate level of planning and design for the requirements of each client.

With siting, designing, and supervising the construction of all types of tailings management systems in every major mining district around the world, we have pioneered and advanced the development of alternative tailings management technologies, such as sub-aqueous systems, drained sub-aerial systems, paste tailings disposal, and dewatered filtered tailings systems. We provide complete and comprehensive design and operational expertise for tailings management tailored to the specific features of each site and needs of each client.

We have designed award-winning integrated waste and water management systems for mining projects. These systems involve a thorough understanding of the site-specific hydrometeorology, surface water and groundwater hydrology, waste characterization, environmental and permit limitations, and client preferred operational philosophies. Probabilistic modeling is commonly adopted to confirm that all extreme scenarios are identified and addressed in order to meet sustainability objectives.

Our overall understanding of the critical components of a successful mine development allows us to develop optimized and environmentally safe operations. Our expertise in waste characterization, field and laboratory testing, numerical modeling, and the practical application of preventative strategies has been applied to numerous successful mining projects at various stages from initial development to permitting and from operation to closure.

Our experience in mine slurry and water pipelines and pump stations ranges from design, specification, and construction supervision, including test monitoring, followed by operational assistance and performance monitoring. By tailoring pump and pipeline selection to a range of flows, pressures, and material conditions anticipated over the project life, we ensure cost-effective and environmentally sound slurry and water handling. Our extensive experience in the management and handling of slurry streams includes tailings, concentrates, and cyclone sands.

From relatively straight forward sites to those in physically and environmentally challenging locations, our experience in designing heap leach pads encompasses all locations and sizes and includes some of the largest heap leaching operations in the world. Expertise is provided in a variety of liner and solution collection systems, loading, and solution management strategies, including for high fines content ores and wet and cold regions applications.

Probabilistic modeling is commonly adopted to confirm that all extreme scenarios are identified and addressed in order to meet sustainability objectives.

Our integrated and multidisciplinary expertise in post-operational site security and risk management is used to develop closure plans for new and existing mining operations that are compatible with the surrounding environment, regulatory requirements, and cost efficiency considerations. Our engineering design and construction experiences provide the expertise for accurate reclamation cost estimating and establishing appropriate surety amounts.

A comprehensive energy strategy is paramount to achieving cost-effective mining operations. Our approach in incorporating renewable energy schemes into existing and planned mining projects can improve your triple bottom line through renewable energy resource evaluation and integration. We also assist mining operations in reducing energy costs with an in-house developed tool used to optimize the schedule for maintaining or replacing various power consumption components.

Through all phases of mining, we offer a full complement of environmental and social expertise integrated with our mining project development services to support timely acquisition of all required permits. Services include the assessment of water, acid rock drainage/metal leaching (ARD/ML) potential, air, biological, and social environments. Additionally, our environmental and social studies are tailored to certify compliance with international lending institution standards, thereby expediting project financing.
