# Ur-Energy Commences Operations at its Shirley Basin ISR Project, Wyoming, Advancing U.S. Uranium Production Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/ur-energy-commences-operations-at-its-shirley-basin-isr-project-wyoming-advancin--a2be3c04-cd1b-4818-9701-a12dc9a279f2 Original source: https://money.tmx.com/en/quote/URE/news/6894147447715722/ur-energy-commences-operations-at-its-shirley-basin-isr-project-wyoming-advancin Publisher: tmx Original announcement: 2026-04-23T11:00:00.000Z 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: Production, Resource update - Extracted: 2026-09-19 03:31:18 UTC Narrative sentiment: 0.80 · Bullish ## Minestarters Atlas summary Ur-Energy has commenced uranium mining operations at its Shirley Basin ISR project in Wyoming. The project features a Measured and Indicated resource of approximately 9.1 million pounds of U3O8 at 0.22% eU3O8 and will utilize existing infrastructure at the Lost Creek facility. Reasoning: The announcement marks a major operational milestone \(transition from development to production\) and provides specific resource and capacity metrics. - Positive factor: Commencement of operations at Shirley Basin ISR project - Positive factor: Integration with existing Lost Creek infrastructure - Positive factor: Significant expansion of total production capacity to 4.2 million lbs U3O8 - Positive factor: Strong resource base of 9.1 million lbs U3O8 Facts used in scoring: 2 ## Classification and evidence **Production Start** Polarity: positive Story-specific tag Definition: No canonical definition is currently available. Why it applies: Company announced the start of uranium mining operations at Shirley Basin. Evidence · text > is pleased to announce the start of uranium mining operations at its Shirley Basin Project in Wyoming. **Measured Resource** Polarity: positive Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves. Why it applies: The document explicitly states the resource includes Measured and Indicated categories. Evidence · text > Measured and Indicated mineral resources totaling approximately 9.1 million pounds U3O8 **QP/CP Signed** Polarity: positive Definition: 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. Why it applies: Qualified Persons are named and responsible for the technical disclosures. Evidence · text > Qualified Persons Benjamin J. Schiffer, P.G., and Ray B. Moores, P.E., ... have reviewed the technical disclosures ## Extracted facts Stored fact records: 1.

Basis for Probable Reserves. Why it applies: category is "indicated" **Cut-off Undisclosed** Polarity: negative Definition: High-grade interval reported without stating the cut-off grade used for compositing. Why it applies: no cutoff\_grade was stated **QP/CP Signed** Polarity: positive Definition: 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. Why it applies: qp\_signed is true **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: reporting\_standards includes ni\_43\_101 **No QP/CP Disclosure** Polarity: negative Definition: No Qualified Person or Competent Person named — lower credibility for the estimate. A QP/CP should be a member of a recognized professional association with relevant experience. Why it applies: no Qualified or Competent Person is named anywhere in the release ## 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.
