The project also includes an Inferred resource of 64 million tons at 0.31% copper, containing 394 million pounds. This updated MRE, prepared by an independent Qualified Person and compliant with NI 43-101, will be used for a Preliminary Economic Assessment expected in early January 2025. Reasoning: US Copper Corp reported a substantial update to its Moonlight-Superior Project's Mineral Resource Estimate, showing a 99% increase in Indicated contained copper to 2.5 billion pounds. The estimate is NI 43-101 compliant and will form the basis for an upcoming Preliminary Economic Assessment, indicating significant progress for the project. - Positive factor: Significant increase in Indicated contained copper \(99%\) - Positive factor: Large overall resource size \(2.5 billion lbs Indicated copper\) - Positive factor: Resource update supports upcoming PEA - Positive factor: QP signed off on the estimate and NI 43-101 compliant Facts used in scoring: 72 ## 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: A current resource fact retains the disclosed cut-off grade **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The source explicitly discloses a revised resource estimate Evidence · text > Updated Mineral Resource Estimate ## Extracted facts Stored fact records: 72.

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.
