Fladgate Exploration Consulting Corporation

True Grit Engineering (TGE) was retained to provide Environmental and Civil Engineering services to Fladgate Exploration Consulting Corporation (Fladgate) for their Pickle Crow Mine Site located in Pickle Lake, Ontario. The services provided included the following:

  • Permit to Take Water (PTTW) Application
  • Groundwater Modelling of Mine Works Dewatering
  • Industrial Sewage Works Environmental Compliance Approval (ECA) Application, Design and Operation Plan
  • Conceptual Tailing Dam Design

The projects completed by TGE for Fladgate encompass a wide range of areas of expertise including geology, hydrogeology, hydrology, geotechnical engineering, civil engineering, and environmental permitting and approvals.

Project Description

TGE prepared an application for a PTTW and all required supporting investigations and reports for their planned advanced exploration and dewatering of Shaft #1 at the Pickle Crow Mine site. Detailed groundwater flow modelling was conducted in support of the PTTW application and was submitted to the Ontario Ministry of the Environment and Climate Change (MOECC) in support of the application.

TGE also prepared a detailed design and operations plan to support an application for amendment to the existing Industrial Sewage ECA for the proposed dewatering, treatment and discharge of water from the existing underground workings. This plan employed a novel Geotube technology and lagoon for the treatment of water from the dewatering process to ensure the treated water met applicable regulatory requirements when discharged to the environment.

TGE was subsequently retained to prepare a design brief for conceptual level design for the existing Tailings Management Facility (TMF) for a five year mine operation with an estimated 370,000 tonnes of tailing residues. This conceptual design utilized the existing TMF and materials to the extent possible, providing an economically viable solution for construction. In addition, the tailing embankment characteristics such as stability, erosion, hydrology, materials and construction were analyzed and a water quality monitoring program was proposed.
