With respect to the coffer dam component and temporary pond / lake removal component of the Project,
there are numerous historic mining sector precedents and other more modern projects at the permitting
stage that involve the construction of coffer dams and/or diversion or removal of waterbodies. A partial
list of precedents is provided in the bullets below.
- Steeprock iron mines, Ontario.
- Pamour Pit expansion, Ontario
- Kapuskasing Mine, Ontario
- Snap Lake Mine, Northwest Territories
- Meadowbank Mine, Nunuvut
- Hammond Reef mine (permitting phase), Ontario
- Côté Gold Project (permitting phase), Ontario
- Lake St. Joseph Iron mine (proposed), Ontario.
In addition to having long established reference documents from government agencies and industry
organizations to provide guidance regarding the design, construction and operation of coffer dams, there
are contractors and project managers available in eastern Canada who are experienced in such
undertakings. As with all components of the Project, FMG would utilize experienced designers and
builders for the coffer dam component of the Project.
