$427,536 (year 50) from Stantec estimate. Maintenance is captured on the Post-Closure sheet with a value that matches Corey's estimate.

A Class 5 estimate completed by Stantec in 2022 estimates $427,536.04 for filling pipelines with ground and sand, which Kidd anticipates will be an acceptable reclamation approach for the regulator. Another estimate from the same year and third party estimates $960,882.80 for the removal of pipelines except those which are beneath concrete foundations.

Removal of rail line outside the site boundary - 27 additional km. Needs further consultation with Northland Rail. Best case $0, but there are areas with historical ore spills. Full removal of rail line unlikely. Could use $33,295 from above, but it would increase as distance gets further from the site.
