Filing Released Lang Actions
News release - English.pdf
Regulatory Filings Classification · 75% confidence The document is a corporate press release detailing exploration drilling and silver assay results at the Pampa Medina deposit. It contains operational updates, drilling highlights, and technical tables rather than financial results, governance changes, or formal filings like annual or quarterly reports. It is not an earnings release, investor presentation, or management change announcement. Therefore, it falls under the general regulatory announcement category (‘RNS’).

News release - English.pdf
Regulatory Filings Classification · 25% confidence The document is a TSX/ASX press release dated April 2, 2026 by Marimaca Copper Corp. detailing high‐grade silver assay results from ongoing exploration drilling at the Pampa Medina deposit. It is an operational exploration update, not a financial earnings announcement, capital raising, governance filing, or management change. It does not announce publication of any formal report, nor does it serve as a slide deck presentation. Therefore, it does not match any of the specific categories and falls into the fallback “Regulatory Filings” bucket.

52-109F1 - Certification of annual filings - CFO (E).pdf
Regulatory Filings Classification · 56% confidence The document is a Form 52-109F1 Certification of Annual Filings under Canadian NI 52-109, containing the CFO’s attestation on disclosure controls and internal control over financial reporting. It is not the annual report itself, nor an earnings release, proxy statement, or dividend notice, but a standalone regulatory compliance filing. It does not announce a report publication nor present full financial statements. Therefore, it best fits the general “Regulatory Filings” category.

52-109F1 - Certification of annual filings - CEO (E).pdf
Regulatory Filings Classification · 85% confidence The document is a standalone certification (Form 52-109F1) by the CEO under Canadian National Instrument 52-109, certifying the issuer’s annual filings. It is not the full annual report (10-K/Annual Report), not an MD&A or audit opinion, nor an earnings release or management discussion itself. There is no specific category for a NI 52-109 certification, so it falls into the fallback “Regulatory Filings” category.

Annual information form - English.pdf
Regulatory Filings Classification · 95% confidence The document is explicitly titled 'ANNUAL INFORMATION FORM' (AIF) for Marimaca Copper Corp. for the year ended December 31, 2025. In Canadian securities regulation, an Annual Information Form is a disclosure document that provides material information about the company, its business, and its risks, which is distinct from the audited financial statements (10-K equivalent). Since the provided categories do not include a specific 'AIF' code, and it is a comprehensive regulatory disclosure document, it falls under the 'Regulatory Filings' (RNS) category as the most appropriate fallback.

Annual MD&A - English.pdf
Management Reports Classification · 96% confidence The document is clearly Management’s Discussion and Analysis (MD&A) for the year ended December 31, 2025 and 2024. It is titled “MANAGEMENT’S DISCUSSION AND ANALYSIS,” provides detailed explanation of financial results, business trends, outlook, and notes to the audited financial statements. It is far more substantive than an announcement or summary and does not include full financial statements, so it is not an Annual Report (10-K) or Quarterly Report (IR). This matches the definition of a Management Report (MDA).
