Bulletin summary

We have received a Notice of Material Change for the Dome Mine that will result in Goldcorp Canada Limited (Newmont Porcupine) submitting a closure plan amendment.

Why consultation isn't required

This bulletin is for information only, as a closure plan amendment is not an instrument under the Environmental Bill of Rights, 1993. The Ministry of Mines is posting this bulletin to the Environmental Registry to keep the public informed of changes to mining projects in Ontario. If you wish to comment on this Closure Plan Amendment, please use the contact information for Katrina Lauzon below.

Bulletin details

The proposed changes to the project are as follows:

  • updated site infrastructure;
  • construction of new emergency spillway on No. 6 TMA;
  • construction of a seepage collection system to collect seepage around the TMA;
  • tailings dam raises to facilitate future deposition of tailings, including access roads and temporary stockpiles for construction;
  • construction of a north extended buttress; and
  • storage of pamour effluent treatment plant (ETP) sludge within the No. 6 TMA.
