The United States has a minerals problem. Defense systems, semiconductors, and electric vehicles all depend on a narrow list of raw materials, and a significant portion of global supply runs through China.
President Trump is scheduled to host a roundtable with top mining executives on August 7, 2026, bringing together leaders from major firms including Rio Tinto, BHP, and Freeport-McMoRan to discuss how domestic and allied mineral production can be accelerated.
What the administration is actually trying to do
In February, Trump announced a $12 billion initiative to build a national mineral stockpile, a reserve designed to cushion the US economy and military against sudden supply disruptions, the mineral equivalent of the Strategic Petroleum Reserve.
Then in July 2026, an executive order went further, restricting defense contractors from obtaining waivers that allow them to source critical minerals from prohibited foreign suppliers. In plain terms, if a defense firm was quietly buying materials from a sanctioned supply chain and getting a pass on it, that pass is now significantly harder to obtain.
The National Mining Association has publicly supported the push for greater resource development collaboration, lending the initiative a degree of industry buy-in before the executives even sit down.
Why this matters beyond a single meeting
China controls a substantial share of global rare earth processing capacity, even for minerals that are mined elsewhere. That means a country can be technically mining its own ore and still depend on Chinese facilities to turn it into something usable.
The three companies confirmed at the table are not small players. Rio Tinto is one of the largest mining companies in the world by market capitalization, with operations spanning copper, iron ore, lithium, and aluminum. Freeport-McMoRan is the dominant US-listed copper producer, and copper is foundational to electrification and weapons systems alike. BHP, the Australian giant, covers a similarly broad portfolio of strategic commodities.
For the defense industry, the July executive order tightening waiver rules creates immediate pressure. Contractors who relied on flexibility in their sourcing now face a harder compliance landscape, which creates demand for exactly the domestic and allied supply the administration wants to cultivate.
Australia, where BHP is headquartered, is both a close US ally and one of China’s largest commodity trading partners.
