Copper and the 2018 Critical Minerals List – Considerations for Resource Policy Reform

While we’re still waiting for policy makers and other stakeholders to take further action, in 2018 an important step was taken to set the stage for mineral resource policy reform with the release of the Department of Interior’s List of 35 Minerals Deemed Critical to U.S. National Security and the Economy. Throughout the drafting stage and subsequent commenting phase, ARPN had lamented the omission of Copper and several other gateway metals from the list.

Citing ARPN’s Dan McGroarty, Earth Magazine contributor Veronica Tuazon zeroes in on this omission in a recent piece for the American Geosciences Institute’s monthly publication.

“Copper is essential in electrical wiring and transportation and is playing an increasingly large role in alternative energy, as it is a crucial component in wind turbines, solar panels and electric vehicles, which require four times as much copper as conventional gas vehicles. But it is also the gateway to several elements on the critical list that are produced as a byproduct of copper mining, as Daniel McGroarty of the American Resources Policy Network, a virtual think tank focused on resource development, pointed out in a series of comments submitted about the DOI’s draft critical minerals list. He also noted that zinc, nickel and lead should be included on the list for the same reason. McGroarty argued that copper is of the highest priority because it ‘is the practical access point to at least four minerals on the DOI List,’ referring to cobalt, rhenium, tellurium and, potentially, the rare earths.”

Tuazon points out that while USGS, which worked with DoI to put together the list of 35, acknowledged the “co-production issue,” Copper was excluded from the list because the risk of supply disruptions for Copper was considered “very low,” according to Steven Fortier, director of the USGS National Minerals Information Center.

However, says Tuazon:

“[W]ith rapid technological advancement and growth, what actually is and isn’t critical changes over time and often eludes simple categorizations. Or as McGroarty puts it, ‘as technology changes, what was once considered minor can have major impacts.’ For example, there was virtually no demand for strontium in the United States before the 1960s, when it was suddenly needed in relatively large quantities to reduce radiation emitted by early televisions.”

While the United States’ net import reliance for copper may currently be pegged at 34 percent it should be noted that we also have a 600,000 MT copper gap each year – the gap between what we consume and what we produce.

Against the backdrop of Copper’s growing list of applications and increased usage in one of the key growth markets – EV battery technology (as visualized here) – analysts anticipate Copper consumption to greatly “outstrip supply as it is slated to increase more than six times.”

On a global scale, with over 200 currently-operating Copper mines slated to reach the end of their production cycle before 2035, CRU analyst Hamish Sampson estimated in the spring of 2018 that “unless new investments arise, existing copper mine production will drop from 20 million tonnes to below 12 million tonnes by 2034, leading to a supply shortfall of more than 15 million tonnes.”

Sampson argued that only if “every single copper project currently in development or being studied for feasibility is brought online before then, including most discoveries that have not yet reached the evaluation stage, the market could meet projected demand.”

With a lack of mega-projects coming on stream before the mid-2020s and global production for Copper expected to peak by the second half of 2019 one thing is clear: Whether or not Copper (and its fellow gateway metals) is excluded from the list of 35 critical minerals — It cannot be excluded from policy considerations in 2019.
