# Silverco Mining Commences 30,000-Meter 2026 Drill Program at Cusi, Targeting Massive Step-Out Potential and Regional Blue-Sky Prospects Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/silverco-mining-commences-30-000-meter-2026-drill-program-at-cusi-targeting-mass--9b8ce31f-8e50-4c80-aae5-bdfed80b9aef Original source: https://money.tmx.com/en/quote/SICO/news/8867932645625573/silverco-mining-commences-30-000-meter-2026-drill-program-at-cusi-targeting-mass Publisher: tmx Original announcement: 2026-03-17T12:30:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Silverco Mining Ltd. - Ticker: SICO - Exchange: TSX - Region: Chihuahua State, Mexico - Primary commodity: Silver - Secondary commodities: Gold, Lead, Zinc - Document categories: Resource update, Drill results - Extracted: 2026-09-14 23:00:39 UTC Narrative sentiment: 0.60 · Bullish ## Minestarters Atlas summary Silverco Mining has commenced a 30,000-meter drill program at its Cusi Mine in Mexico, targeting significant resource expansion and new regional discoveries. The fully funded program will also support the operational restart of the mine in late 2026. The company highlighted existing mineral resource estimates for the San Juan, San Miguel, and Promontorio East areas, which include Measured, Indicated, and Inferred categories for silver, gold, lead, and zinc. Reasoning: Silverco Mining has commenced a substantial, fully funded 30,000-meter drill program at its Cusi Mine, targeting significant resource expansion and new discoveries, while also preparing for an operational restart. The announcement provides context with existing resource estimates, but the primary news is the new drilling campaign. - Positive factor: Large 30,000-meter drill program commenced - Positive factor: Program is fully funded - Positive factor: Targets massive step-out potential and regional blue-sky prospects - Positive factor: Aims for aggressive resource expansion and testing high potential exploration targets - Positive factor: Supports operational restart preparation for Cusi Mine - Positive factor: QP sign-off for technical information - Negative factor: Resource estimates presented are not new updates, but existing figures - Negative factor: Metal equivalent assumptions for AgEq are not fully disclosed for economic recoverability Low confidence — this extraction should be reviewed alongside the original source. Facts used in scoring: 34 ## Classification and evidence **Step-Out Extension** Polarity: positive Definition: Mineralization extended beyond the previously known limit. Why it applies: The drill program is targeting a massive, near 600-meter step-out to connect highly successful 2025 intercepts with historical drilling, aiming to extend mineralization. Evidence · text > Surface drilling is targeting a massive, near 600-meter step-out to connect highly successful 2025 intercepts with historical drilling. **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 technical information, including the resource estimates, has been reviewed and approved by Nico Harvey, P.Eng., a Qualified Person as defined in NI 43-101. Evidence · text > The scientific and technical information contained in this news release has been reviewed and approved by Nico Harvey, P.Eng., Vice President Project Development of Silverco, a Qualified Person as defined in National Instrument 43-101. **Metal Equivalent Opaque** Polarity: negative Definition: Metal equivalent grade reported without disclosing the price, recovery, or payability assumptions used. Requires an actual metal equivalent grade; a combined elemental basket such as PGE is not a metal equivalent. Why it applies: The document states that AgEq is a reporting metric only and does not imply economic recoverability, indicating that the underlying assumptions for the metal equivalent calculation are not fully disclosed. Evidence · text > that AgEq is a reporting metric only and does not imply economic recoverability **Stale Data Re-release** Polarity: negative Definition: Historical results re-announced with no new assays or reinterpretation — low genuine novelty. Why it applies: The document references past drill results from 2025 and historical intercepts, which are not new assays from this announcement. Evidence · text > During the 2025 campaign, Silverco successfully intercepted 6.8 metres grading 255 g/t AgEq in drillhole CU-25-59 \( released in February 26 2026 news release \), which followed up on an historical intercept of 4.3 metres grading 472 g/t AgEq in drillhole DC21B955. **Measured Resource** Polarity: positive Definition: Highest confidence category — tonnage, grade, shape well-established from closely-spaced drilling. Basis for Proven Reserves. Why it applies: The Promontorio East area includes a Measured resource category, which is the highest confidence level for mineral resources. Evidence · table > Measured Context: Promontorio East **Indicated Resource** Polarity: positive Definition: Reasonable geological confidence based on adequate drilling; continuity can be assumed. Basis for Probable Reserves. Why it applies: The San Juan, San Miguel, and Promontorio East areas all include Indicated resource categories, indicating reasonable geological confidence. Evidence · table > Indicated Context: San Juan **Inferred Resource** Polarity: negative Definition: Speculative category — limited drilling, geological continuity assumed but not confirmed. Cannot support economic studies alone. Why it applies: The San Juan, San Miguel, and Promontorio East areas all include Inferred resource categories, which is a speculative category with limited drilling. Evidence · table > Inferred Context: San Juan **QP/CP Signed** Polarity: positive 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: Nico Harvey, P.Eng., a Qualified Person as defined in NI 43-101, has reviewed and approved the scientific and technical information, including the resource estimates. Evidence · text > The scientific and technical information contained in this news release has been reviewed and approved by Nico Harvey, P.Eng., Vice President Project Development of Silverco, a Qualified Person as defined in National Instrument 43-101. **NI 43-101 Compliant** Polarity: positive Definition: Resource estimate prepared in compliance with NI 43-101 \(Canada\) — high reporting standard. Why it applies: The resource estimates refer to a 'Ni 43-101 Technical report prepared by SGS Geological Services' for details. Evidence · text > Please refer to the Ni 43-101 Technical report prepared by SGS Geological Services **Resource Update** Polarity: neutral Definition: Revised estimate for an existing resource — compare to prior to assess progress. Why it applies: The document presents existing mineral resource estimates for several areas, indicating a review or re-presentation of current resources rather than a new estimate. Evidence · text > an area that remains largely outside the recent Mineral Resource Estimate update. ## Extracted facts Stored fact records: 34.

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.
