Highland Copper Announces Successful Completion of Copperwood Early Site Work and White Pine Drill Program
Highland Copper Company Inc. provided key updates at its 100% owned Copperwood project and the White Pine North project, its joint venture with Kinterra Copper LLC.Highland Copper continues to execute on its path to a near-term construction decision at Copperwood through completion of required early site work and preparation for detailed engineering. In parallel at White Pine, completion of a significant drill program and key environmental baselining studies represent important progress toward engineering studies and permitting. The two projects are well sequenced, highly leveraged to copper price, and create a strong copper production growth profile in the supportive Upper Peninsula of Michigan, USA. Copperwood Update: 2024 Site Work: Highland announced that it has substantially completed its early site work program as required by its Wetlands and Streams Permit. This program includes partial site clearing, in addition to the construction of mitigating wetland areas and site stream diversion structures. The Company will complete the on-site work with landscaping and tree planting in 2025, in addition to an off-site stream mitigation project. The work has allowed Highland to establish an operating presence, demonstrate strong environmental stewardship and strengthen relationships with local authorities and stakeholders. Safety & Environmental: The site work was completed with no environmental incidents and one reportable safety incident through 2023 and 2024. In addition to constructing approximately 18 acres of on-site wetland, Highland is also establishing a 717-acre wetland preservation area. In combination, Highland is creating and preserving wetland areas approximately twelve times greater than wetland areas impacted. Highland believes that industry and environmental protections can coexist and is committed to meeting Michigan’s high standards. Permits: The substantial completion of this site work satisfies key obligations under the Wetland and Streams Permit, maintaining the permit in good standing. Highland is currently renewing the Part 55 Air Permit, which expect to complete by First Quarter 2025.State Grant: In January 2024, the Michigan Economic Development Corporation proposed a $50 million grant to assist with infrastructure expenditure during construction. The Michigan Strategic Fund and Michigan House Appropriations Committee approved the grant in March 2024 and June 2024, respectively. The grant is pending final approval by the MichiganSenate Appropriations Committee. Highland continues to educate the committee on the merits of the project. Construction Team: In September 2024, Highland hired Dr. Wynand van Dyk as the Project Director for the Copperwood project. Wynand is a senior executive with 30 years of experience in mining, metallurgy and capital projects at De Beers, Hatch, Lonmin Platinum, and Itafos, in addition to consulting engagements for numerous senior producers. Wynand’s scale of experience will support Copperwood as it advances to final project design and development. Detailed Engineering: Highland has initiated bidding for key detailed engineering work packages including mine engineering, process plant engineering, water management and tailings disposal facility engineering, in addition to internal work on the site power plan. This engineering is critical to both derisk and optimize Copperwood’s design, as well as support due diligence during project financing. Highland will adopt a phased approach to engineering with the initial step finalizing design criteria for key work packages and assessing key opportunities to improve the project. Of particular note, Highland may consider the applicability of ultrafine flotation technology to improve recoveries. Union Engagement: Highland signed a letter of intent with the Michigan Building and Construction Trades Council reflecting the collective goal to sign a Project Labor Agreement. This agreement would assure construction work on Copperwood proceeds economically, efficiently, safely, without interruption, and with due consideration for the protection of labor standards, wages, and working conditions in Michigan. Highland has received a formal letter of support from all unions represented by both the Michigan Building and Construction Trades Council and the Upper Peninsula Construction Council. White Pine Update: While Highland focuses on the Copperwood project, its joint venture partner, Kinterra, is applying its technical and financial strength to the White Pine project. Drilling Programs: In January 2024, White Pine concluded a winter drill program of 10 holes or approximately 6,600 metres. The primary goal of the drill program was to collect ore samples for geotechnical and metallurgical testing to support further engineering studies. In October 2024, White Pine completed a second drill program of 14 holes, or approximately 14,200 metres, including 28 wedges. At the conclusion of the drill programs, sufficient metallurgical and geotechnical samples have been collected to support key engineering studies. A resource update is planned for the first half of 2025 which will include infill holes from the second drill program.Test work and Engineering Trade-offs: Geotechnical test work is continuing on samples collected to date. Engineering trade-off studies are also underway to evaluate mining methods, mine access options, and material handling systems. Metallurgical test work has been initiated with the main objective of developing a flowsheet to maximize metal recovery. It primarily consists of grinding and flotation test work on multiple variability samples. Environmental Baselining: Environmental baseline studies have been completed for surface water flow and water quality monitoring, groundwater elevation and water quality monitoring, aquatic habitat, threatened and endangered species, wetlands and streams, wildlife habitat, and archaeological and cultural surveys. Environmental baselining will continue through 2025. This baselining is a key initial step to support permit applications. Kinterra Loan: Highland is funding its share of joint venture expenditures on White Pine by drawing down on the loan facility provided by Kinterra. As of the last fiscal reporting date, June 30, 2024, Highland has a loan outstanding of $2.4 million. Expenditure has accelerated during the quarter-ended September 30, 2024.
