Allen Palmiere, President and CEO, said, “This is a fantastic opportunity to showcase our initial site plans.1 to key community stakeholders, especially tribal communities. Although the initial site plans took into consideration the historical concerns expressed, we are interested in learning about any other concerns that may arise during the assessment. Our priorities while advancing the Back Forty Project feasibility study and licensing initiatives are focused on positively impacting our environmental, social and governance programs while identifying economic and operational efficiencies.

Steve Donohue, Vice President, Environmental and Regulatory Affairs (Michigan), will represent the company at SEIA. The image gallery and enhancements listed below describe the materials to be presented at the SEIA meeting.

The optimized initial site plan highlights the following project improvements over the 2018 project:

  • Combined surface and underground mine
  • The pit is smaller and removed from Menominee River and River Road
  • Installing filtered tailings (dry stack) eliminates the traditional tailings dam and therefore the need for a dam safety permit; streamlines water management of the tailings management facility, including at closure.
  • Addresses the Administrative Law Judge’s decision regarding the analysis of alternatives (2019 Wetland Permit Disputed Case)
  • Eliminates a waste storage facility near neighboring properties and wetlands
  • Reduced impacts of dredging and infilling of wetlands (now less than 2 acres)
  • Reduction of visual intrusion on the Menominee River and identification of cultural resources.

Revised initial mine plan consists of a smaller open pit and incorporates underground mining1. The open pit mine is farther from the Menominee River and does not cross River Road. The underground mine does not pass under the Menominee River.

Here are the planned permit applications that will be filed after the publication of the feasibility study:

  • Part 632 Mining Permit Application
  • Part 632 Environmental Impact Assessment
  • Air permit application (installation permit)
  • Modification of the NPDES permit
  • Part 301/303 Wetland Permit Application

Caution regarding the feasibility study

In order to qualify as a « feasibility study » within the meaning of SK 1300 subpart 1300 (« SK 1300 »), the study must meet certain requirements, including, for example, that the estimates of operating and investment costs in the study must, at a minimum, have a level of precision of approximately ± 25% and a contingency range not exceeding 15%. As the Company has not yet completed its analysis for the proposed study, there can be no assurance that the study, when completed, will meet the definition of a “feasibility study” as defined in SK 1300.
