Reopening Abandoned Copper Mines: A Fast Track to Meeting Demand and the Growing Need for Mining Professionals
Introduction
Copper, often referred to as “the metal of the future,” is essential for the clean energy transition and the technology driving it. With demand soaring, the mining industry in North America faces a significant challenge: how to supply the copper needed without the prolonged timelines of new mine development. Recently, several companies have turned to an alternative approach - reopening abandoned copper mines—as a way to fast-track output and meet market needs. This strategy is not without its obstacles, but it could play a critical role in the global copper supply chain. However, the rapid expansion of these initiatives has underscored an additional challenge: the urgent and growing need for skilled mining professionals to sustain industry growth.
The Demand Surge for Copper
The demand for copper has surged due to its crucial role in electrification. Electric vehicles, solar panels, and wind turbines all rely on substantial copper resources. The clean energy transition alone has created a steady, high demand, while the growth in artificial intelligence and data centers has further boosted copper’s role in the tech sector (1).
Projections suggest that copper production needs to increase by approximately 50% by 2030 to keep pace with demand (2). Yet, new mining projects can take over a decade to develop, with costs often reaching $5 billion or more. This lengthy timeline and high cost have driven companies to seek alternative sources for faster copper production.
Reopening Abandoned Mines: A Strategic Move
In response to these challenges, mining companies are revisiting previously shuttered mines. Many of these mines, closed years ago due to fluctuating copper prices or outdated technology, still hold substantial copper deposits. By investing in these abandoned sites, companies can avoid the extensive permitting processes and developmental hurdles associated with starting a new mine.
Key examples include:
Minto Mine (Yukon, Canada): After multiple closures and ownership changes, this mine is undergoing revitalization to increase its copper output and tap into its remaining reserves (3).
Pumpkin Hollow Mine (Nevada, USA): Recently revived, this mine is working to overcome initial startup difficulties and scale production to serve both domestic and international markets (4).
These sites alone have the potential to add millions of metric tons to the copper supply in the coming years, offering a faster and potentially more cost-effective path to meeting global demand.
Challenges on the Fast Track
While reopening abandoned mines provides an accelerated timeline, it is not without risks and challenges. First, the existing infrastructure in these sites may require significant upgrades to meet modern operational and environmental standards. Mines closed in previous decades often lack the technological advancements necessary for sustainable production. Companies must invest in updating these facilities to meet current regulatory and efficiency requirements, which can be costly and time-consuming (5).
Additionally, reopening mines can still encounter environmental permitting issues. Many abandoned sites are located in areas where environmental concerns are heightened, and reopening them can attract scrutiny from local communities and environmental organizations. Mining companies need to navigate these complex permitting landscapes, balancing production goals with sustainability commitments (6).
The Growing Need for Mining Professionals
The rapid expansion of mining activities, including the reopening of abandoned mines, has intensified the demand for skilled professionals in the sector. A recent McKinsey survey revealed that 71% of mining leaders find talent shortages are holding them back from delivering on production targets and strategic objectives. Furthermore, 86% of mining executives believe it is harder to recruit and retain the talent they need compared to two years prior, particularly in specialized fields such as mine planning, process engineering, and digital (data science and automation) (7).
This talent gap is exacerbated by an aging workforce and a decline in the number of graduates in mining-related disciplines. Recent figures indicate that the total number of mining engineering degrees awarded in the U.S. in 2021 was 314, a decline of 41% compared to the peak of 533 degrees awarded in 2016. With the U.S. needing around 500 to 1,000 mining engineers annually, but only producing around 200 graduates, the talent shortage is critical (8).
Addressing the Talent Shortage
To bridge this gap, mining companies are implementing several strategies:
Educational Partnerships: Collaborating with universities to develop curricula that align with industry needs and attract students to mining careers.
Upskilling Programs: Investing in training programs to enhance the skills of existing employees, particularly in digital technologies and automation.
Diversity and Inclusion Initiatives: Expanding recruitment efforts to underrepresented groups to broaden the talent pool.
Global Recruitment: Looking beyond domestic borders to attract skilled professionals from other countries.
Conclusion
Reopening abandoned copper mines in North America is emerging as a viable strategy for meeting the increasing copper demand quickly. This approach allows mining companies to bypass some of the most time-consuming and costly aspects of new mine development, potentially accelerating copper output within a few years. However, the success of these initiatives hinges not only on overcoming operational and environmental challenges but also on addressing the critical shortage of skilled mining professionals. By investing in talent development and implementing strategic recruitment and training programs, the mining industry can ensure it has the workforce necessary to meet future demands and sustain growth.
