| US, critical minerals |
US Army critical minerals leases will place four commercial processing facilities on military installations for the first time, marking a new approach to securing domestic supplies of graphite, lithium, boron and rare earths.
US Army critical minerals leases were conditionally awarded to Empire State Mines, Energy X, Ioneer USA and REalloys on 25 June. The facilities are expected to begin development in 2027, with initial operating capacity targeted by or before 2028.
US Army critical minerals leases are strategically significant because they move critical mineral processing directly onto federal military property. The model reduces the need for the government to build and operate the facilities itself while creating a dedicated pathway for private investment.
The initiative also reflects a broader shift in US industrial policy. Washington is increasingly focused on processing capacity, not just access to mineral deposits, because refining and conversion remain major vulnerabilities in defense supply chains.
Military Land Becomes a Platform for Mineral Processing
The four companies will focus on different critical materials. Empire State Mines will process graphite, Energy X will target lithium, Ioneer USA will process boron, and REalloys will handle rare earths.
These materials serve different markets, but all have strategic relevance. Graphite and lithium are key battery inputs, rare earths support permanent magnets, and boron is used in advanced materials, glass, ceramics and selected defense applications.
The projects will be developed through the Army’s Enhanced Use Lease model. This allows underutilized military land to be leased to private-sector companies while the Army remains the landlord.
The commercial operators will bear the costs of financing, designing, building, operating, securing and eventually decommissioning the facilities. They must also pay rent at or above fair market value.
This structure limits direct government construction risk while still giving the Army influence over where strategic processing capacity is located.
The model could also shorten parts of the project-development process if sites already have suitable infrastructure, security and federal oversight. That could make military installations attractive locations for strategically sensitive processing projects.
Defense Policy Shifts Toward Domestic Processing Capacity
The leases are part of the Army’s Strategic Capital Initiatives, which aim to use private investment to accelerate military modernization and supply-chain resilience.
The significance lies in the processing stage. The US has identified numerous domestic and allied mineral resources, but many still depend on overseas refining or conversion before they can enter defense manufacturing.
Locating commercial plants on military property signals that processing is increasingly viewed as strategic infrastructure. The Army is effectively using its land base to support industrial capacity that private markets have struggled to build quickly enough.
The approach has already been tested outside critical minerals. The Army has used similar lease structures for a Hanwha Defense USA munitions facility and data center projects involving Carlyle and CyrusOne.
If the mineral projects reach production on schedule, the EUL model could become a repeatable tool for other materials. It offers the government a way to support domestic capacity without taking full ownership or construction responsibility.
For the wider market, the message is clear. US critical minerals policy is moving further downstream, with processing, refining and conversion becoming central to defense supply security.
The Metalnomist Commentary
The Army’s lease awards turn underused military land into industrial infrastructure for critical minerals. The model could become important if it proves capable of moving processing projects from policy support to commercial production faster than conventional development routes.
