# NUBIAN PROVIDES UPDATE ON ESQUILACHE SILVER-ZINC PROJECT, PERU Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/nubian-provides-update-on-esquilache-silver-zinc-project-peru--2e5271e8-5868-47c2-9fac-89801bee4622 Original source: https://money.tmx.com/en/quote/CPI/news/8450795926200578/nubian-provides-update-on-esquilache-silver-zinc-project-peru Publisher: tmx Original announcement: 2022-12-07T12:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Nubian Resources Ltd. - Ticker: NBR - Exchange: TSX - Region: Peru - Primary commodity: Silver - Secondary commodities: Zinc, Gold, Copper, Lead - Document categories: Drill results, Other - Extracted: 2026-09-13 19:28:53 UTC Narrative sentiment: 0.10 · Bullish ## Minestarters Atlas summary Nubian Resources provided an update on its 100% owned Esquilache Silver-Zinc Project in southern Peru. The company contracted Atticus Geoscience Consulting to compile and re-model historical data, identifying 26 additional veins with significant mineralization. The project database includes historical drilling from 2009-2015 by previous operators, with significant silver, gold, copper, lead, and zinc intercepts. Nubian plans to design infill drill programs to advance the project towards a feasibility evaluation, but no new field work has been conducted by Nubian to verify the veins. Reasoning: Nubian Resources provided an update on its Esquilache Silver-Zinc Project, focusing on the re-modelling of historical drill data and future plans for infill drilling and feasibility studies. While the re-evaluation of historical data is positive, the drill results themselves are not new, and no current field work has been undertaken by the company. - Positive factor: Re-modelling identified additional veins with significant mineralization - Positive factor: Plans for infill drilling and feasibility studies indicate future project advancement - Positive factor: Technical information approved by a Qualified Person - Negative factor: All drill results presented are historical and not new discoveries - Negative factor: No new field work has been conducted by Nubian to verify veins - Negative factor: True widths of intercepts are not known, potentially overstating apparent thickness Facts used in scoring: 102 ## Classification and evidence **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The drill results presented in the document are explicitly stated as historical, from previous operators \(Vena Resources, 2009-2015 and 2014\). Evidence · text > Table 1. List of historical drill holes with significant mineralization, Mamacocha Zone \(Vena Resources, 2009-2015\). **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 document explicitly states that true widths are not known for the reported assay intervals. Evidence · text > The Company notes that in Tables 1 and 2, true widths are not known. As such, assay intervals are reported as drill core lengths. **QP/CP Signed** Polarity: positive Story-specific tag 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: Steven Park, Project Manager for Nubian, is a Qualified Person within the meaning of NI 43-101 and has approved the technical information. Evidence · text > The technical information contained in this news release relating to Esquilache has been approved by Steven Park , Project Manager for Nubian, who is a Qualified Person within the meaning of National Instrument 43-101, Standards of Disclosure for Mineral Projects. **Nearology Play** Polarity: neutral Definition: Value premise rests on proximity to a known deposit rather than own results. Why it applies: The document highlights the project's location on trend with major silver, gold, and copper projects including Las Bambas, Tintaya, San Gabriel in Peru and Eloro's Potosi silver deposit in Bolivia. Evidence · text > Esquilache is located in the Cordillera Occidental of southern Peru and Bolivia , on trend with major silver, gold, and copper projects including Las Bambas, Tintaya, San Gabriel in Peru and Eloro's Potosi silver deposit in Bolivia. **Epithermal Deposit** Polarity: neutral Story-specific tag Definition: No canonical definition is currently available. Why it applies: The document describes the Esquilache vein system as 'polymetallic, low- to intermediate-sulfidation, epithermal to mesothermal veins'. Evidence · text > Esquilache covers the mineralized core of a large caldera structure that hosts a system of polymetallic, low- to intermediate-sulfidation, epithermal to mesothermal veins containing silver, lead, zinc, copper and significant gold grades. ## Extracted facts Stored fact records: 102.

Why it applies: the fact restates a prior 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.
