Narrative

Elk Creek is a planned underground mine and processing plant in southeast Nebraska, owned by NioCorp since 2010. Its feasibility study of August 2026 is the first to include rare earths: on average 672 t/yr of separated NdPr oxide, 67 t/yr of dysprosium oxide and 17 t/yr of terbium oxide, plus mixed samarium-europium-gadolinium and heavy rare earth carbonates, together about a quarter of projected life-of-mine revenue, alongside ferroniobium, scandium oxide and titanium tetrachloride. The study puts capital cost at $1.849 billion and development at 35 months from financing, without a calendar year for first production. Financing remains undrawn: the Export-Import Bank of the United States has progressed the project through a letter of interest, a preliminary project letter and an independent technical review, none binding, and a Department of Defense award of up to $10 million is aimed at scandium. Rare earth offtake is covered by non-binding term sheets with Stellantis and Traxys. NioCorp listed on Nasdaq through a SPAC merger in 2023, raised about $466 million of equity in fiscal 2026, and began building a mine portal in February 2026 without a final investment decision.

How this page is sourced

Everything here comes from public sources — company filings, annual reports, exchange announcements, government releases and trade press. Every figure is linked to the document it came from and carries the date that document was published, because a capacity number without a date is not a fact, it is a rumor with a decimal point.

What is deliberately absent: material nonpublic information. I have spent more than two decades in this industry and a good deal of what I know about these companies I learned under NDA. Those obligations do not expire and they do not bend for a website. Nothing I have been told in confidence appears here in any form, and nothing on this page — or missing from it — should be read as a signal about what I know privately. I hold NDAs absolutely. It is the reason clients tell me things.

Judgment is the other thing left out on purpose. This page reports what has been published and who published it. Whether a target is credible, whether a ramp will hold, whether a capacity figure survives contact with the plant behind it — that is the work I do for clients, and it does not belong in a free reference page.

Where public sources disagree, I say so rather than picking a winner. Where a figure has not been published, the field says so rather than carrying an estimate. An empty field is information too.

Public filings tell you what a company has said. Whether it holds up is a different question, and the one I get hired to answer.
