Summary
Ur-Energy has filed an updated S-K 1300 Initial Assessment Technical Report Summary for its Lost Creek Property, effective December 31, 2025. The report highlights a 47.4% increase in post-tax NPV to $244.1 million and a 45.7% increase in post-tax net cash flow to $442.2 million, with an extended mine life to Q2 2039. The updated mineral resource estimate includes 11.868 million pounds eU3O8 in Measured and Indicated categories and 10.357 million pounds in Inferred, after accounting for historical production.
Reasoning: The updated technical report for Lost Creek shows significantly improved economics with a higher NPV, IRR, and net cash flow, along with an extended mine life. While Measured and Indicated resources saw a slight decrease post-production, overall contained metal and future production estimates increased, indicating a robust project.
Positive factors
- Significant increase in post-tax NPV (47.4%) and net cash flow (45.7%) compared to prior report.
- Extended mine life by nearly three years.
- High post-tax IRR of 65.7% indicates strong project economics.
- Increase in estimated pounds remaining to be produced despite two years of production.
- Updated resource estimate maintains substantial Measured and Indicated categories while significantly increasing Inferred.
Negative factors
- Decrease in Measured and Indicated pounds (5.2%) after accounting for production, though total contained metal increased.
Low confidence — this extraction should be reviewed alongside the original source.
Facts used in scoring: 16
Classification and evidence
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: A current resource fact retains the disclosed cut-off grade
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: The source explicitly discloses a revised resource estimate

Why it applies: qp_signed is true
NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: reporting_standards includes ni_43_101

Inferred Resourcenegative
Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone.
Why it applies: category is "inferred"
Cut-off Disclosedpositive
Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.
Why it applies: cutoff_grade is stated
QP/CP Signedpositive
Qualified Person (QP) or Competent Person (CP) named and signed off — a member of a recognized professional association (e.g., AusIMM, SME, AIG, P.Geo) with relevant experience.

NI 43-101 Compliantpositive
Resource estimate prepared in compliance with NI 43-101 (Canada) — high reporting standard.
Why it applies: reporting_standards includes ni_43_101
Contained Metal Growthpositive
True scale improvement — contained metal ounces/tonnes increased vs prior, accounting for both tonnage and grade changes.
Why it applies: 10357 against 6807 previously
Resource Updateneutral
Revised estimate for an existing resource — compare to prior to assess progress.
Why it applies: the release compares against a previous estimate

Reasoning: The combined Measured and Indicated resource is substantial, forming a solid foundation for the project, despite a minor reduction post-production.
Positive factors
- Large Measured + Indicated resource base provides high confidence for project development.
Negative factors
- Slight decrease (5.2%) in Measured and Indicated pounds after accounting for production.

How Atlas produces this analysis
Minestarters Atlas uses automated extraction to summarize mining announcements, identify reported measurements, and classify supporting evidence. Sentiment reflects the extracted narrative and classification rules; it is an interpretation, not a reported measurement. Evidence quotes and context are provided where available. Missing data, low-confidence results, and review flags indicate limitations. Check the original publisher announcement before relying on an interpretation.
