The company also announced the appointment of a new General Manager for its Chilean subsidiary and provided details of the existing copper-gold mineral resource estimate. Reasoning: The announcement marks the start of a significant resource-conversion drilling campaign at a large copper-gold project, providing a clear operational roadmap. - Positive factor: Commencement of a large 40,000m infill drilling program - Positive factor: Existing resource base of ~357 Mt - Positive factor: Clear path toward feasibility study - Negative factor: Historical drill results at Tricolor are from 2018 Facts used in scoring: 3 ## Classification and evidence **Infill Drilling** Polarity: neutral Definition: Confirmatory drilling to raise resource confidence, not new discovery. Why it applies: The 40,000m program is explicitly described as infill drilling to support resource conversion. Evidence · text > 40,000-metre infill drilling program underway at Dos Amigos in support of a planned feasibility study **QA/QC Disclosed** Polarity: positive Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release details the use of certified standards, blanks, and duplicates for the 2018 Tricolor drilling. Evidence · text > The Company employed a rigorous QAQC program involving certified standards, blank, ¼ core duplicates and coarse reject duplicates. **Apparent Width Only** Polarity: negative Definition: Interval given as downhole width with no true width or drill orientation — apparent width may overstate true thickness. Why it applies: The Tricolor intercept does not disclose true width or drill orientation, noting the orientation of mineralization is unknown. Evidence · text > The current orientation of mineralization is unknown therefore the intercept may not reflect true widths. **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 ## Extracted facts Stored fact records: 3. Some facts used in scoring do not have a stored record. ## Drill Results (1) ### Fact 1 [Link to this fact](https://atlas-extractions.minestarters.com/news/tintina-mines-announces-commencement-of-drilling-at-the-dos-amigos-project-in-ch--056bf63d-fc32-4248-b0a8-02d239dffc42#fact-drill-facts-2) Dos Amigos · copper Historical result Needs review: drill\_no\_hole\_id #### Identity - Project: Dos Amigos - Commodity: copper - Region: chile - Reported Region: chile - Ticker: TTS.V #### Geometry - Grade: 0.56 - Grade Unit: % - Intercept: 230 m #### Classification - Sample Type: drill #### QA/QC - QA/QC Disclosed: Yes - QA/QC Methods: standards, blanks, duplicates #### Compositing - Dilution Disclosed: Yes #### Review - Needs Review: Yes - Review Reason: drill\_no\_hole\_id - Interp.

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.
