Checking a Mining Company’s U.S. Incorporation Would Not Reveal Who Ultimately Owns It—or Where Its Ore Goes

Three accountability questions, not one ownership test

The Bureau of Land Management can improve its records of whether mining claimants meet U.S. citizenship requirements without learning the full extent of foreign ownership of federal mines—or how much of their production leaves the country. Those are separate gaps in the government’s critical-minerals picture, a comparison of two federal investigations shows.

What’s the Scoop With Broach examined the methods, legal distinctions and denominators in GAO-27-108196 and GAO-27-108094, both dated October 6 and publicly released October 16, 2026. The comparison establishes the reach and limits of the first report’s proposed repair: collect and document claimant citizenship information. It would help test legal eligibility, but the second report shows why domestic incorporation is not a substitute for tracking parent ownership or mineral destinations.

Under the mining-claim system, qualifying claimants generally include U.S. citizens, certain citizenship applicants and entities organized under U.S. state or territorial law. A U.S.-incorporated subsidiary of a foreign business can qualify. A foreign parent therefore does not, by itself, establish an unlawful claim. The rules also distinguish claimants from operators; the reports identify no citizenship requirement specifically for operators hired to extract minerals.

Seven unresolved incorporation checks are not seven proven illegal mines

GAO first compared 236 claimant names that appeared to be businesses with OpenCorporates incorporation records. It matched 162 to U.S.-incorporated entities. Of the remaining 74, it selected fifteen for further examination: all seven names matching Canadian records, plus eight randomly selected unmatched names. This was a targeted, nongeneralizable sample, not fifteen randomly selected claimants from all federal mining.

Additional searches found U.S. incorporation evidence for eight of those fifteen, including three that also matched Canadian records. Seven remained unconfirmed. GAO explicitly cautioned that differences in data entry could explain some missing matches and that some of the unresolved entities might be incorporated in the United States. BLM could not resolve the cases because it generally did not collect or document claimant citizenship information.

It would therefore be wrong to convert seven divided by fifteen into a national rate of ineligible claims—or to describe the seven as adjudicated illegal operators. The established finding is a verification failure: neither GAO’s additional searches nor BLM’s records could settle their eligibility. GAO recommended directing staff to collect citizenship information and document compliance. The recommendation remained open on the public report page checked October 19. Interior did not provide comments on that report; Agriculture had no comments.

The ownership denominator changes the apparent share

The companion review studied a different group: 43 U.S.-incorporated claimant or operator companies associated with 59 identified critical-mineral mining plans on BLM-managed lands. GAO determined ownership for 32 and identified fourteen subsidiaries of foreign parents. Eleven companies’ ownership remained unresolved.

Fourteen is 43.8% of the 32 companies with determined ownership, but 32.6% of the full 43-company group. Neither figure measures the foreign-owned share of all federal mines, their acreage, their production or their mineral value. Companies can be associated with multiple mines; a company count is not a mine count. The identified fourteen are a documented minimum within the examined group, not a complete national ownership census.

None of the fourteen had a Chinese parent company. GAO did identify Chinese financial interests in at least two foreign parents, including approximately 11% and 12% stakes in two examples. That is different from establishing that China owned or controlled all fourteen U.S. subsidiaries. GAO did not review the companies’ legal documents and expressly offered no legal opinion on the parent-subsidiary relationships.

Domestic incorporation does not answer this ownership question. The mining law does not require claimants and operators under the location system to disclose foreign parents to BLM. The reports also describe the narrower beneficial-ownership reporting regime following Treasury’s August 2026 final rule, including the exemption for domestic companies. A claimant-incorporation record cannot fill that separate ownership-information gap.

National export totals cannot be assigned to federal mines

The companion report analyzed Census export records and found more than two billion kilograms of selected unprocessed hardrock critical minerals exported in 2025, worth more than $11 billion. But those national totals do not identify whether minerals came from federal land. BLM and the Forest Service do not track extraction quantities for these mines, according to officials cited in the report. The amount extracted specifically from federal lands for export is therefore unknown.

The distinction matters for promises of domestic mineral security: producing ore in the United States, having a legally eligible claimant and keeping processing or supply chains domestic are not interchangeable outcomes. The report identifies limited U.S. processing capacity as an important constraint. It does not prove that any named foreign shareholder caused an export, a security breach or a lost domestic supply.

There are existing national-security controls. The Committee on Foreign Investment in the United States can review covered transactions, mitigate risks and refer transactions to the president; Treasury told GAO that foreign investment in a parent controlling a U.S. mining subsidiary could fall within its jurisdiction. The absence of a BLM ownership census does not mean foreign investments are exempt from all federal review.

This investigation reconciles two published federal record analyses and recalculates their denominators. It does not claim access to confidential CFIUS reviews, independently classify corporate control or reproduce GAO’s subscription-database searches. Commerce and Treasury provided technical comments on the companion report. The public accountability question remains specific: which system will establish eligibility, which will identify ultimate ownership, and which will connect federal extraction to downstream supply? The proposed citizenship repair answers only the first.
