What Are Strategic Minerals and Why Do They Matter?
Strategic minerals are raw materials deemed essential for a nation's economic and national security. In the United States, these minerals play a crucial role in various industries, from defense and aerospace to renewable energy and automotive manufacturing. The challenge? The U.S. currently imports a significant percentage of these critical minerals, creating vulnerabilities in supply chains and national security.
According to Mark Smith, CEO of NioCorp Developments, "This mine is desperately needed in the United States… We import 100% of the niobium and scandium we need." This stark reality highlights the urgency of addressing America's strategic mineral dependencies.
Defining Strategic Minerals in the U.S. Context
Strategic minerals are non-fuel mineral resources that:
- Are essential for economic prosperity and national defense
- Face supply chain vulnerabilities due to limited domestic production
- Are subject to potential supply disruptions from geopolitical tensions
- Have few or no viable substitutes in their applications
The Strategic Vulnerability Gap
Currently, the United States faces significant import dependencies for numerous critical minerals:
- 100% import reliance for niobium
- 100% import reliance for scandium
- 75% import reliance for titanium
- Near-total import reliance for magnetic rare earth oxides
- Heavy reliance on China for processing many of these materials
The statistics paint a concerning picture: China controls approximately 60% of global titanium processing and dominates rare earth production and refinement. These dependencies create strategic vulnerabilities that extend beyond economics into national security concerns.
How Are Strategic Minerals Used in Key Industries?
Strategic minerals serve as the foundation for numerous advanced technologies and applications across multiple sectors of the U.S. economy, with their importance growing as technology advances.
Defense Applications
Strategic minerals are essential components in military hardware:

Global manufacturers recognize this critical need. Thyssenkrupp of Germany has already secured a 50% offtake agreement for NioCorp's future niobium production, demonstrating the international competition for these resources.
Which Strategic Minerals Is the U.S. Most Dependent On?
The United States faces critical supply vulnerabilities across several key mineral categories, with some dependencies reaching 100%.
Rare Earth Elements
Rare earth elements (REEs) represent perhaps the most significant strategic vulnerability:
- Magnetic Rare Earths: Neodymium, praseodymium, dysprosium, and terbium are essential for permanent magnets used in electric vehicles, wind turbines, and defense applications
- Heavy Rare Earths: Dysprosium and terbium are particularly critical for high-temperature applications
- Supply Challenge: China controls approximately 60% of global rare earth production and approximately 90% of processing capacity
- U.S. Status: Currently imports virtually all magnetic rare earth oxides
According to Smith, "We have zero [heavy rare earths like dysprosium] produced in the U.S. today," a situation that creates extreme vulnerability for high-tech manufacturing.
Niobium
Niobium represents another critical vulnerability:
- Key Applications: Adding just one pound of niobium to a ton of steel can double its yield strength, making it essential for infrastructure and construction
- Market Dynamics: Demand remains strong in both public infrastructure projects and private construction
- U.S. Status: 100% import dependent, with no domestic production
The strength-to-weight benefits of niobium-enhanced steel cannot be overstated. This metal enables everything from safer vehicles to more resilient infrastructure, yet the U.S. has no domestic production.
Scandium
This lesser-known but increasingly important mineral faces complete import dependence:
- Key Applications: Strengthens aluminum alloys, making them lighter, more corrosion-resistant, and weldable
- Emerging Markets: Aerospace, automotive, and sporting goods industries
- U.S. Status: 100% import reliant with virtually no domestic production
Smith emphasizes that scandium-aluminum alloys enable "robotic welding in aerospace manufacturing," a critical capability for advanced manufacturing processes.
Titanium
While less import-dependent than other minerals, titanium still presents challenges:
- Key Applications: Critical for aerospace, defense, medical devices, and industrial applications
