Projects

Technical resource supporting Selkirk’s engagement on the Casino Gold project, a vast open pit gold-copper mine including mineral processing and heap leach. Focus areas include mine waste management, water treatment/management, heap leach design, and cyanide management.

Senior technical resource for the permitting phase review of the Blackwater Gold project, a large open pit gold mine with gold recovery via cyanidation. Focus areas include cyanide management, hazard assessment, water treatment, water quality/water balance modeling, and long term reclamation costing.

Senior technical resource for the Environmental Assessment phase review of the Cariboo Gold Project, an underground gold mine and gold processing facility. Focus areas include water treatment for cyanide degradation residue and water quality/water balance modeling.

Senior technical resource supporting local First Nations governments on matters related to water and tailings treatment and management for the oil sands sector. Contributes scientific and regulatory understanding related to the development of treated water release policy for the sector at the federal and provincial level.

Senior technical resource contributing to the Selkirk First Nation team for the Faro Mine Remediation Project including the current care and maintenance of the site and the long term remediation plan. Focus areas include water treatment, contact water capture, and water management.

Collaborative engagement with proponent’s consultants on the Tailings Technology BAT Assessment and the Water Quality Mitigation BAT Assessment including mine mitigation design and cyanide management. Conducted review of bonding related to mine closure, water treatment, and cyanide detoxification.

Review for mine water management, water treatment, mine closure and mitigation planning in this collaborative process with Newmont. The project involves cyanide heap leaching, cyanide detoxification, and water treatment.

Technical support for the evaluation of mine waste management and water management options associated with potentially acid generating material and cyanide residue.

Project lead for the evaluation of technology for treatment and discharge of excess water stored on site. Executed on-site piloting of a unique and integrated sulphate treatment system using nanofiltration followed by scoping level engineering and risk assessment to support full scale implementation. Represented proponent for regulatory and First Nations engagement via Technical Advisory Committee and associated reporting. Prepared roadmap for engineering required to support permit application.

Senior technical resource for selenium treatment piloting. Project lead for the evaluation of water management and treatment options to significantly reduce lifecycle cost and environmental risk for the project. Represented the proponent in meetings with Canadian and US regulators as well as with potential investors.

Project lead for pre-feasibility level process engineering of water treatment, focused on management of selenium, metals and sulphate.

Led scoping level engineering and laboratory treatability assessment of selenium removal to support the remediation of a coal combustion residue pond in the US power generation sector.

Project lead to identify cost-effective measures for preventing and mitigating acid mine drainage from legacy waste rock at a remote site. Conducted field work and laboratory work to demonstrate methods.

Contributed to issued-for-construction design of modular mine water treatment plant and subsequent support for operations, including technical issues, operator training, standards development and life-of-mine regulatory engagement. Project lead for designing and implementing a bolt-on system for ammonia treatment. Senior technical resource for the piloting and planning of contingency measures for selenium treatment.

Senior technical resource in the development, piloting, design and operations planning for selenium water treatment on the Kemess Underground project. Collaborated with other consultants in water quality modeling, regulatory engagement, and permitting support.

Senior technical resource for selenium treatment piloting. Conducted multiple options evaluations and laboratory programs for different projects in the years following.

Expert report on the discharge permit appeal.

Conducted a review of water treatment options for selenium and other contaminants to address concerns raised by the First Nations Independent Technical Review team. Represented proponent in subsequent regulatory and First Nations engagement.

Technical lead for feasibility level process engineering of water treatment of selenium, metals and sulphate. This included technology evaluation, flow sheet development, and laboratory treatability study to optimize system. Collaborated with other consultants through review of water quality modeling.

Project lead for pre-feasibility level process engineering of mine water treatment, focused on management of selenium, metals and sulphate. Supported proponent in subsequent regulatory engagement.

Developed flowsheet and conducted pre-feasibility level process engineering for water treatment, focused on management of selenium and sulphate. Supported proponent in subsequent regulatory engagement during EA.

Technical lead for executing a selenium treatment pilot followed by multiple options evaluations and laboratory programs to trial different flowsheet variants on different contaminated waters.

Project lead for execution of a sulphate treatment pilot from industrially impacted water. Supported subsequent regulatory engagement on behalf of the proponent.

Technical lead providing operational support of a client’s industrial water treatment facility. Contributed to test planning, data analysis and generation of design criteria for scale up.

Developed a novel process for capture of nickel and cobalt from laterite tailings and recovery of otherwise lost metal value in existing metallurgical flow sheets. This program involved broader study of the use of ion exchange for mine waste remediation and collaboration with a major ion exchange manufacturer to develop new ion exchange resins.

Conducted electrochemical studies to investigate the kinetics of atmospheric chalcopyrite leaching and the role of pyrite in catalyzing this process. Developed mathematical models of reaction kinetics of various sulphide minerals.
