Uranium production by company and operation

Methodology

What counts as production

Production on this site means dried and drummed (packaged) U3O8: finished product ready for delivery to a converter or customer. It is the stage the U.S. EIA uses for uranium concentrate output and the only stage comparable between in-situ recovery and conventional producers. When a company does not disclose drummed production for a period, the headline reads Not disclosed. No upstream stage is ever substituted for it.

Stages

Each figure is stored under the stage the company reported, with the company's own wording kept verbatim: ore mined (contained pounds in ore extracted), ore stockpiled, ore milled, loaded on resin (uranium captured on ion-exchange resin), precipitated (eluted and precipitated as slurry or wet cake), dried and drummed (the headline), shipped (delivered to a converter or customer) and sold. Sold pounds may include purchased material, so sales are never read as production. Figures are never summed across stages.

100% basis and attributable

A 100% basis figure is the operation's total output; an attributable figure is the company's share. Operation pages and operation rows show 100% basis; company pages and every cross-company total use the attributable basis, because adding 100% figures across joint-venture partners would count Inkai, Cigar Lake and McArthur River twice. Where a company reports only one basis and its ownership share is cited on the operation, the other basis is derived by applying that share and carries a derived badge with the note. Cameco's share of JV Inkai is a purchase entitlement that differs from its 40% interest, so it is never derived.

Guidance and attainment

Annual production guidance stays in the guidance tracker, with its revisions and withdrawals. Where quarterly drummed production exists on the same basis as a company's guidance window, the hub shows year-to-date production against the guided range and as a share of the range midpoint, labelled as the midpoint. Guidance on a different basis or in a different unit is not compared.

Sources, verification and revisions

Every figure is copied from a company document: a quarterly MD&A or 10-Q, an ASX quarterly activities report or a results release, with the document URL, publication date, location and a verbatim quote. Figures appear as soon as they are entered; rows that have not yet been checked a second time carry an unverified badge. A revised figure is stored as a new row that supersedes the old one, which is kept, and the revised badge shows the chain.

Units and reporting periods

Figures are kept in the unit the company used and normalised to pounds of U3O8 through one shared conversion module: pounds, thousand pounds and million pounds are exact scale changes; kilograms and tonnes of U3O8 use 2.204623 lb per kg; tonnes of uranium metal use the U3O8 mass fraction of 0.848 from the same module. Every row carries real calendar dates, so a June-year reporter such as Paladin or Boss aligns with a calendar-year reporter by date overlap, never by label.

Granularity by company

Data is stored at the most granular level each company reports: per operation for Cameco, per mill facility for Energy Fuels (finished U3O8 is produced at the White Mesa Mill), per mine for Paladin and Boss, and at company level where only a consolidated figure exists. A company total uses one level only, the operation rows when every listed operation reported, otherwise the company-level row, never both.
