Highland Copper Company Inc. says it has initiated site activity at its Copperwood project in the western Upper Peninsula.
Particularly, it has completed wetland impacts and initiated the related environmental mitigation projects as required by its permit obligations and in line with Highland’s goal to operate in an environmentally friendly manner. This represents a key step towards project financing and development. Highland is also pleased to provide a project update on key areas of the project including community relations and technical optimization work.
- Completed key Copperwood site impacts and initiated related environmental mitigation projects.
- Satisfied initial wetland permit obligations and maintained permits in good standing.
- Site work performed on budget with no lost time or reportable environmental incidents.
- Increased regional and State stakeholder engagement levels; considerable project support demonstrated.
- Focus over the coming months shifting to key technical optimizations to improve economic strength of the Copperwood project.
As previously disclosed by Highland, certain early site works needed to be completed during 2023 to meet obligations under the Wetlands and Streams Permit. Highland is pleased to report that all work required to maintain that permit has been completed to the satisfaction of the Michigan Department of Environment, Great Lakes, and Energy (“EGLE”). As a result, Highland confirms that all key Michigan State permits remain in good standing. Moreover, it has allowed Highland to initiate pre-construction activities including site clearing and grubbing focused on wetland and stream areas, the development of stream relocation infrastructure, improvements to existing site roads, and the initiation of key environmental mitigation projects. Particularly, compensating wetland has been constructed to offset wetland impacts. The site work was performed safely and in line with the Company’s internal budget. Certain environmental mitigation activities will continue over the next one-to-two-year period. Please see the site photos at the end of the news release demonstrating the scale and scope of work performed.
“Initiating work at the Copperwood site is a significant step for Highland Copper for a number of reasons. Critically, we completed key activities required to meet our State permit obligations. Moreover, the work program allowed us to build out our local team in the Upper Peninsula and engage several key local contractors, beginning to drive economic benefits into the region. As well, we increased engagement with key local stakeholders and State authorities and have continued to build regional support for the development of Copperwood. We look forward progressing Copperwood along the development path,” stated Interim CEO Barry O’Shea.
While initiating on-the-ground activity, Highland has kept all key stakeholders appropriately informed. This includes periodic stakeholder meetings to deliver project updates. As a demonstration of support, a range of local authorities have provided resolutions of support for the Copperwood project. This includes resolutions from Gogebic County (where Copperwood is located), Ontonagon County, the City of Ironwood, the City of Bessemer, the townships of Ironwood, Bergland, Carp Lake and Erwin, as well as the Western Upper Peninsula Planning and Development Region Commission, just to name a few. Additionally, Highland has interfaced with key State authorities, particularly EGLE, to ensure the site work has been performed in accordance with Highland’s permit obligations and State standards.
“It is important to Highland that we are aligned to local communities and State authorities. Since joining Highland, I have had the opportunity to attend numerous meetings of local cities, townships and county boards. I have been pleased to see the level of engagement and support. We are also continuing to develop a healthy working relationship at the State level to ensure we operate to the standards expected by the State,” said Mike Foley, Copperwood Site Manager.
The western Upper Peninsula has a rich mining history. Since mining left the region, its economic strength has diminished in the last several decades. Highland has commissioned a third party to prepare a report evaluating the potential regional economic contribution of developing and operating the Copperwood project. While Copperwood is expected to generate significant direct investment and employment, there is also expected to be a considerable indirect economic contribution. The report is expected to be completed in the near term and Highland will provide an update when the report is published.
While the economic returns of Copperwood are robust, Highland is evaluating key opportunities identified in the Feasibility Study with a goal of demonstrating potentially improved economic returns. These opportunities include:
- Potential Life of Mine Extensions: The Copperwood Measured and Indicated Resource, on which the initial 11-year mine life is based, is 54 million ore tonnes at a copper grade of 1.51%. There is a further 79 million ore tonnes of Inferred resource at a copper grade of 1.09%. Highland is evaluating the cost and economic impact of converting Inferred tonnage to Measured and Indicated.
- Application of Bulk Ore Sorting: Initial test work, based on a limited ore sample, demonstrated that Copperwood ore may be amenable to bulk ore sorting technology. Bulk ore sorting can have the impact of lowering mill throughput and increasing copper grade. Highland is currently evaluating potential methods for extracting a sufficient bulk ore sample to test ore sorting at a feasibility study level.
- Metallurgical Recoveries and Reagent Usage: If access is available to a bulk ore sample, Highland will also assess metallurgical test work to evaluate the recoveries and reagent usage presented in the Copperwood Feasibility Study for potential optimizations.
- Government Funding Opportunities: In addition to technical optimizations, Highland is continuing to pursue sources of State and federal funding to assist with the development of Copperwood. In August 2023, the US Department of Energy added copper to the Critical Metals List. Highland is assessing its eligibility for tax credits, in addition to federal funding.
Highland looks forward to updating the market on these initiatives in the coming months.
