Two weeks after the U.S. Geological Survey rebuffed a bipartisan call from members of Congress for an “out-of-cycle”addition of copper to the U.S. Government’s official List of Critical Minerals, House Republicans from Western mining states are pushing to achieve the “critical mineral” designation for copper via legislation.

Arguing that changing copper’s designation would allow the federal government to more efficiently ensure reliable and secure supplies of the material in the future, Representative Juan Ciscomani (R-Ariz.) is introducing the “Copper is Critical Act.”  The bill is co-sponsored by Reps. Dan Newhouse (R-Wash.), Jim Baird (R-Indiana), and David Schweikert (R-Ariz.), Eli Crane (R-Ariz.), and Debbie Lesko (R-Ariz.)

The bill would amend section 7002 of the Energy Policy Act of 2020, and represents the first time this process is used in an attempt to broaden the scope of the U.S. Critical Minerals List.

As followers of ARPN well know, ARPN’s Daniel McGroarty has called for the designation of copper as a critical mineral on several occasions, and has submitted public comments to USGS to this effect.

Policy experts agree.

In a recent piece, Cullen S. Hendrix with the Peterson Institute for International Economics argues that while copper is widely mined and processed relative to listed critical minerals on the U.S. government’s list, “the security of diffuse global supply chains and production in US-friendly economies is still vulnerable to disruptions in producer countries. The ability and willingness of copper producing countries to keep supplying copper can change rapidly.”

He points to current trends in Peru, a key copper mining country, where resource nationalism has reared its head, as well as developments in neighboring Chile, that may indeed affect both countries’ “ability and willingness” to supply copper to the global market and elaborated that “designating copper as critical to national and economic security would lead to enhanced scrutiny from the USGS, which tracks minerals markets, production, and reserves. Industry advocates also believe that the designation might lead to streamlined permitting processes that would facilitate more domestic production.” 

With copper’s long list of applications growing in the context of the materials science revolution and with long-term demand scenario surging, ARPN will monitor the Copper is Critical Act as it moves through the legislative process.

In their quest to secure critical mineral supply chains against the backdrop of surging demand and rising geopolitical pressures, stakeholders are leaving no stone unturned – quite literally — and have in fact begun turning the same stone twice.

As Australia’s Financial Post reports, the Australian government has completed a mapping project of sites containing mine waste with reprocessing potential.

The “Atlas of Australian Mine Waste“ was launched this week by Geoscience Australia in partnership with RMIT University, the University of Queensland, as well as geological surveys across the country.

As Minister for Resources and Northern Australia Madeleine King stated, “[s]ome of the minerals we need now, and into the future, may not just be in the ground—they’re also in rock piles and tailings on mine sites around the country.”

She added:

“These minerals might not have been of interest when first extracted but could now be in hot demand as the world seeks to decarbonize—for example, cobalt in the tailings of old copper mines.”

Acknowledging the potential held by mine waste and tailings, the U.S. Geological Survey (USGS) earlier this spring solicited proposals for FY2023 grants to collect data on mine waste, using funds from Bipartisan Infrastructure Act in the context of the Earth Mapping Resources Initiative (Earth MRI).

Earth MRI provides more than $74 million in new mapping funding each year to “modernize our understanding of the Nation’s fundamental geologic framework and improve knowledge of domestic critical-mineral resources both still in the ground and in mine waste.”

As announced this May, more than $5.8 million will go towards mapping critical-mineral resources in Alaska in partnership with the Alaska Division of Geological & Geophysical Surveys. Minerals included in the context of USGS and the Alaska Division of Geological & Geophysical Survey research projects Alaska are: Arsenic, antimony, bismuth, cobalt, graphite, indium, platinum group metals, rare earth elements tantalum, tellurium and tin.

Miners have long realized the potential of reprocessing tailings, and have already “made a business out of reprocessing old mine waste to extract metal, as part of a mine remediation process,” as the Financial Post reports.  Many efforts have sprung up in recent years, and we’re featuring a few examples below:

In Australia, New Century Resources currently owns and runs the largest tailings retreatment operation at its zinc tailings retreatment operation in Queensland.

In the rare earths realm, Reuters lists six major projects outside of China aimed at extracting the critical minerals from waste or byproducts, including Iluka Resources Ltd’s and VHM Ltd’s operations in Australia, Rainbow Rare Earths Ltd’s endeavor in northeast South Africa, Swedish state-owned LKAB’s plans to extract REEs from two existing mines, and two U.S. operations:

Phoenix Tailings, a privately held U.S. company plans to launch operations using waste materials from a former iron ore mine in New York using its own processing technology.

U.S. Energy Fuels, originally focused on uranium production, started acquiring monazite, a byproduct of mineral sands, to extract REEs with plans to open its own separation plant by 2024.

Global miner Rio Tinto began producing tellurium at its Kennecott copper operation in Utah, where roughly 20 tons of the material are generated from by-product streams generated during the copper refining process. As America’s oldest copper mine, now in its 117^th year of operations, there’s no telling how many critical minerals may reside in Kennecott’s historic waste piles.

In addition to recovering tellurium from Kennecott, after commencing production of battery-grade lithium from waste rock at a lithium demonstration site at its Boron mine site in California in 2021, the company last fall began partnering with CR Minerals Co. LLC in an effort to extract a material called pozzolans from the facility’s tailings, which can be substituted for or combined with cement to decarbonization construction materials. Meanwhile, in Canada, the miner is producing scandium from titanium waste, becoming the first North American producer of scandium in the process.

As the materials science revolution marches on and continues to unlock new technologies allowing for the safe and commercially viable recovery of mine waste tailings, harnessing this – to date largely untapped — potential could play a significant role in a comprehensive “all-of-the-above” approach to bolstering critical mineral supply chains.

If history holds one important lesson for us, it’s that most things in life are cyclical. Low tide and high tide, ups and downs, times of war, times of peace.  What holds true on a personal level, also applies to bigger fields like economics. As value investor and author Howard Marks phrased it: “Mechanical things can go [...]

The coronavirus pandemic and associated supply shocks, surging demand for critical minerals against the backdrop of an accelerating global push to net zero carbon emissions, as well as rising geopolitical tensions on the heels of Russia’s invasion of Ukraine and the looming tech war between China and the West have catapulted the issue of securing [...]

The Biden Administration has announced the “most aggressive” plan to curb tailpipe emissions to date, with new vehicle pollution standards proposed by the Environmental Protection Agency (EPA) and announced by the White House last week. If finalized, the proposed rules would require automakers to reduce carbon emissions by 56% in their 2032 models compared to 2026 models.  The expectation is [...]

The time has come for the United States to get “serious about mining critical minerals for green energy,” writes Saleem H. Ali for Nature. Ali points to the inherent irony of the green energy transition — renewable technologies requiring vast and increasing amounts of metals and minerals like lithium, copper, nickel, cobalt, manganese and REEs, but [...]

As ARPN outlined earlier this week, the European Union has dropped its response to the United States’ Inflation Reduction Act passed last summer: the just-dropped Critical Raw Materials Act (CRMA) paired with sister legislation, the Net Zero Industry Act (NZIA), which aims to support investment in manufacturing capacity in ‘net zero emissions’ technologies in Europe. The CRMA not only seeks to streamline [...]

With demand for critical minerals projected to increase dramatically against the backdrop of geopolitical tension and strained supply chains, the European Union has released its long-awaited action plan to “ensure the EU’s access to a secure, diversified, affordable and sustainable supply of critical raw materials.” The Critical Raw Materials Act (CRMA) presented to lawmakers in Brussels on March [...]

When it comes to the metals and minerals underpinning the green energy transition, and specifically the EV battery revolution, much of the spotlight has fallen on lithium — and for good reason, as we will discuss in a forthcoming post.  However, as ARPN’s latest review of the “battery criticals” against the backdrop of the just-released latest iteration of [...]

 In this post, we continue our review of the “battery criticals” (lithium, cobalt, graphite, nickel and manganese) against the backdrop of the just-released 2023 iteration of the USGS Mineral Commodity Summaries.  Next up:  cobalt. With the material accounting for up to 20% of the weight of the cathode in a typical lithium-ion EV battery, cobalt was considered the highest [...]
