# Cerro de Pasco Resources Prepares for Next Phase as Technical and Permitting Work Advances at the Quiulacocha Project Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/cerro-de-pasco-resources-prepares-for-next-phase-as-technical-and-permitting-wor--df2d779f-6390-4bb5-8757-5688cdc13f18 Original source: https://money.tmx.com/en/quote/CDPR/news/7152491478596192/cerro-de-pasco-resources-prepares-for-next-phase-as-technical-and-permitting-wor Publisher: tmx Original announcement: 2025-12-10T14:09:57.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Cerro de Pasco Resources Inc. - Ticker: CDPR - Exchange: TSX - Region: Peru - Primary commodity: Silver - Secondary commodities: Zinc, Lead, Copper, Gold, Gallium - Document categories: Metallurgy, Permitting, Resource update - Extracted: 2026-09-19 15:27:37 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Cerro de Pasco Resources has completed Phase 1 of its Quiulacocha Tailings Reprocessing Project in Peru, including a 40-hole sonic drill program and environmental baseline studies. The company has received positive regulatory resolutions from Peru's Mining Council and is transitioning into Phase 2 drilling and integrated metallurgical testing to support an upcoming maiden Mineral Resource Estimate and feasibility studies. Reasoning: The company is reporting significant technical and permitting de-risking at the Quiulacocha project, transitioning from Phase 1 \(drilling/baseline\) to Phase 2 \(drilling/metallurgy\) with clear regulatory support. - Positive factor: Positive regulatory resolutions from the Mining Council in Peru - Positive factor: Successful bench-scale flotation tests producing base metal concentrates - Positive factor: Completion of Phase 1 sonic drilling \(40 holes\) - Positive factor: Project is fully funded for Phase 2 drilling and metallurgical programs - Negative factor: No formal Mineral Resource Estimate \(MRE\) has been published yet; results are currently supporting an upcoming MRE - Negative factor: Metallurgical flowsheet is still being defined Facts used in scoring: 4 ## Classification and evidence **QA/QC Disclosed** Polarity: positive Story-specific tag Definition: Release includes QA/QC disclosure — certified lab, QP sign-off, or stated methods \(blanks, standards, duplicates\). Why it applies: The release names a Qualified Person \(Alfonso Palacio Castilla\) and mentions work across multiple international laboratories. Evidence · text > Mr. Palacio is a Qualified Person for the purposes of reporting in compliance with NI 43-101. **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: The metallurgical program focuses on flotation and selective leaching. Evidence · text > The initial phase centers on flotation and selective leaching to maximize metal recoveries. **Single Domain Only** Polarity: negative Definition: Testing limited to one composite or domain — representativeness not established. Why it applies: only one composite was tested ## Extracted facts Stored fact records: 4.

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.
