Tas Mohamed, CEO of Railveyor, discusses the current state of critical minerals in the US and progress in strategies to unlock a steady supply.
The race for critical minerals in the US will require accelerated production from local mines, but to do this sustainably and at scale means harnessing smart and innovative technologies.
The US is accelerating efforts to increase domestic production of copper, lithium, niobium and rare earths to fuel the energy transition, protect national security and support high-tech manufacturing. These critical minerals are not optional; they are essential for defence, infrastructure, energy and next-generation technology.
To put it in perspective, a single artificial intelligence (AI) data centre today demands as much electricity as 100,000 households. This is just the beginning; according to the IEA, future AI data centres could consume 20 times more.
Electric vehicles (EVs) account for one in 10 car sales in the US, while globally, they are expected to reach 25% of all car sales this year and grow to 40% by 2030. Another global growth market is in satellites, where Goldman Sachs estimates a seven-fold growth by 2035, with over 70,000 satellite launches expected by then.
All of these technologies depend on critical minerals and rare earth elements, including neodymium, praseodymium, dysprosium and terbium. However, supply is lagging behind demand, with years of underinvestment in the mining sector creating a significant gap. McKinsey estimates that over $5tr in investment is required by 2035 just to meet the rising demand.
Rethinking US minerals strategy
In this context, geopolitical instability is forcing the US to rethink its critical minerals strategy. Current statistics indicate that China controls the production of 77% of the world’s refined rare earth material, 46% of copper and 57% of lithium. This presents a significant risk for the US supply chain, and the current US administration has recognised this.
Through the ‘Unleashing American Energy’ Executive Order, the US has committed to expanding mine exploration and development across the country. This is intended to accelerate permitting, ease regulations and enable faster development of critical mineral projects. Key agencies, such as the Department of Defence, the Department of Energy, and the Department of the Interior, have been empowered to support this shift.
Innovating the way forward
Mining these critical minerals is becoming increasingly challenging. Deposits are deeper, more remote and lower in grade. As a result, mine engineering and metallurgical processing are becoming more complex. Labour shortages are growing as fewer young people enter the mining industry. Additionally, there are the growing demands of environmental, social, and governance (ESG) policies, which are a top priority for mining executives.
The result of these multiple constraints is that the mining sector is now leaning heavily into innovation. Companies like Ivanhoe Electric, for instance, are turning to the Mining, Equipment, Technology and Services (METS) sector for high-impact solutions. Their Santa Cruz project will utilise modern mining technologies to facilitate faster development and more efficient processing.
NioCorp Developments is also playing a vital role in unlocking US critical minerals. By leveraging advanced extraction and processing technologies, NioCorp is helping to secure domestic supplies of niobium, scandium, and rare earths, which are essential for clean energy, defence, and high-tech manufacturing.
From AI and advanced analytics to autonomous haulage systems, innovation is helping the industry become cleaner, safer and more productive.
Proven and available technologies
The good news is that many of these technologies are already available and well-proven. One of the most promising opportunities lies in the electrification of mine haulage, marking a significant shift within the sector. At several emerging US mining projects, energy-efficient electric haulage systems, enhanced by automation and digital technologies, are being used to rethink mine layouts entirely, offering both capital cost savings and long-term flexibility.
Innovative haulage systems with minimal infrastructure requirements are proving successful in reducing both Scope 1 and Scope 2 emissions while enabling faster and more flexible deployment. They also offer the agility to scale production without committing to costly, energy-intensive infrastructure from the outset.
Safe and easy to operate
Mine operators are benefiting from the simple and rugged design of these systems, which are suited to operate in the challenging environment of underground mining. They are safe to operate and maintain, requiring only standard technical training, typical of the underground workforce.
These technologies will increasingly replace diesel-powered equipment alternatives, enabling mines to meet their sustainability goals while achieving ambitious production targets, even in deep and complex ore bodies.
