Do you think the U.S. is heading in the right direction on domestic mineral production?
Federal efforts and rising demand are reviving dormant U.S. mines, including Bunker Hill and Sunshine in Idaho. At least eight notable mines since 2024 have restarted, entered restart construction, or announced formal reopening plans.
Why it matters
Demand for copper, silver, uranium, and antimony used in data centers, power infrastructure, electronics, and defense is driving the resurgence. National-security concerns are pushing new investment into domestic mining to reduce reliance on vulnerable foreign supply chains.
At least eight notable U.S. mines have restarted or announced reopening plans since 2024, with Sunshine alone investing more than $200 million. The USGS lists silver, copper, and uranium among 60 critical minerals, but the reported figures do not yet show how much output these restarts will add.
The players
Bunker Hill Mine
Bunker Hill is a historic silver, lead, and zinc mine in Kellogg, Idaho, which produced its first concentrate in June 2026 after decades without production.
Sunshine Mine
The Sunshine Mine is a silver mine in the Idaho Silver Valley, where the operator has invested more than $200 million and plans a 2028 restart.
U.S. Geological Survey
The U.S. Geological Survey is the federal science agency that maintains the list of 60 critical minerals, including silver, copper, and uranium.
The details
The mines include Bunker Hill and Sunshine in Idaho, Thompson Creek in Idaho, Copper One and Tony M in Utah, Jerritt Canyon and Pumpkin Hollow in Nevada, and San Manuel in Arizona. Bunker Hill produced its first concentrate in June 2026 after decades without production.
Timeline
Since 2024: At least eight notable U.S. mines restarted or announced reopening plans.
June 2026: Bunker Hill produced its first concentrate after decades without production.
2028: Sunshine plans to restart.
Market Landscape
The restarts reflect a federal push to rebuild domestic supply of minerals the USGS lists among its 60 critical minerals, including silver, copper, and uranium. They position U.S. producers to compete with foreign suppliers as demand from data centers, power infrastructure, and defense grows.
Expanded domestic mining could affect the availability and cost of copper, silver, and uranium used in electronics and infrastructure over time. The extraction does not show near-term changes in consumer prices.
The takeaway
Domestic mine restarts are a concrete sign that critical-mineral policy is moving from planning to production. Watch for production figures from restarted sites as the 2028 timelines approach.
