# Ur-Energy Updates Lost Creek Property Technical Report Summary Estimating an Extended Mine Life and Increase in Net Cash Flow Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/ur-energy-updates-lost-creek-property-technical-report-summary-estimating-an-ext--8c9b8d9c-8ebc-4654-8ac5-b0d19e433b33 Original source: https://money.tmx.com/en/quote/URE/news/8261239901675558/ur-energy-updates-lost-creek-property-technical-report-summary-estimating-an-ext Publisher: tmx Original announcement: 2026-03-10T21:40:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Ur-Energy Inc. - Ticker: URE - Exchange: TSX - Region: Wyoming - Primary commodity: Uranium - Secondary commodities: None reported - Document categories: Resource update, Economic study - Extracted: 2026-09-19 03:37:25 UTC Narrative sentiment: 0.70 · Bullish ## Minestarters Atlas 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 factor: Significant increase in post-tax NPV \(47.4%\) and net cash flow \(45.7%\) compared to prior report. - Positive factor: Extended mine life by nearly three years. - Positive factor: High post-tax IRR of 65.7% indicates strong project economics. - Positive factor: Increase in estimated pounds remaining to be produced despite two years of production. - Positive factor: Updated resource estimate maintains substantial Measured and Indicated categories while significantly increasing Inferred. - Negative factor: 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 Disclosed** Polarity: positive Definition: Cut-off grade used for resource reporting is clearly stated, enabling like-for-like comparison.

Why it applies: the release compares against a previous estimate ## 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.
