This study aims to refresh the project's development potential using historical data and updated market inputs, potentially leading to a Preliminary Economic Assessment \(PEA\). Reasoning: The announcement of a new economic assessment engagement is a positive development for project advancement, though it relies heavily on historical data \(low novelty\). - Positive factor: Engagement of Tetra Tech to advance economic assessment - Positive factor: Existing historical data and permit in place - Positive factor: Large molybdenum resource reported Facts used in scoring: 3 ## Classification and evidence **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document discusses the existing 2022 resource in the context of a new economic assessment engagement. Evidence · text > The engagement marks the first step to advance the economic assessment of Ruby Creek ## Extracted facts Stored fact records: 3. Some facts used in scoring do not have a stored record. ## Drill Results (1) ### AD-417 [Link to this fact](https://atlas-extractions.minestarters.com/news/stuhini-engages-tetra-tech-to-advance-economic-assessment-of-ruby-creek-molybden--3ce7648a-ddf8-4ec4-98e6-caad60283b8c#fact-drill-facts-2) molybdenum #### Identity - Hole ID: AD-417 - Commodity: molybdenum - Region: canada\_bc - Reported Region: canada\_bc - Ticker: STU #### Geometry - Grade: 0.23 - Grade Unit: % - Intercept: 45 m #### Classification - Sample Type: drill #### Review - Needs Review: No - Interp. Status: scored - Historical: No #### Dates - Event date: 2025-10-21T00:00:00.000Z Reasoning: Strong intercept at depth mentioned as part of mineralization continuity. - Positive factor: High grade relative to resource average - Positive factor: Significant width Evidence · text > 45 metres grading 0.23% Mo at the bottom of hole AD-417 #### Tags used in scoring **No QA/QC Disclosure** Polarity: negative Definition: Release does not disclose QA/QC — lab certification, CP/QP sign-off and assay protocols cannot be checked from this document. Why it applies: qaqc\_disclosed is not true **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 **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: proximity is offered as the value premise: "The project has seen more than 30 years of exploration and development, including: ~74,000 metres of drilling." ## Resource Estimates (2) ### indicated [Link to this fact](https://atlas-extractions.minestarters.com/news/stuhini-engages-tetra-tech-to-advance-economic-assessment-of-ruby-creek-molybden--3ce7648a-ddf8-4ec4-98e6-caad60283b8c#fact-resource-facts-0) Ruby Creek · molybdenum Historical result Needs review: historical\_restatement #### Identity - Project: Ruby Creek - Commodity: molybdenum - Region: canada\_bc - Reported Region: British Columbia - Ticker: STU #### Resource scope - Estimate type: resource - Resource group id: resource:42ca6cf9cd0f66fd6e41 #### Resource Data - Category: indicated - Tonnes: 369400000 - Grade: 0.053 - Grade Unit: % - Contained Metal: 433 - Contained Unit: million pounds #### Review - Needs Review: Yes - Review Reason: historical\_restatement - Historical: Yes - Historical Source Date: 2022-03-15T00:00:00.000Z #### Dates - Event date: 2025-10-21T00:00:00.000Z Reasoning: This is a restatement of the 2022 NI 43-101 resource estimate. - Positive factor: Large tonnage and contained metal - Negative factor: Historical data re-release Evidence · text > 433 million pounds of molybdenum in the measured and indicated category \(369.4 million tonnes at 0.053% Mo\) #### Tags used in scoring **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. 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 **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: the release compares against a previous estimate **PEA-Supporting** Polarity: neutral Definition: Resource estimate prepared to support a Preliminary Economic Assessment — early-stage study.
