# Pampa Medina Continues to Deliver Extraordinary Cu-Ag Grade-Widths - Drilling Intersects 216m of 1.0% Cu and 7.2g/t Ag Including 62m of 2.2% Cu and 21.5g/t Ag from SPRD-15 Canonical Atlas analysis: https://atlas-extractions.minestarters.com/news/pampa-medina-continues-to-deliver-extraordinary-cu-ag-grade-widths-drilling-inte--6c96ad14-cdaf-4bcd-b470-fe065c73bd8f Original source: https://money.tmx.com/en/quote/MARI/news/5254243640586196/pampa-medina-continues-to-deliver-extraordinary-cu-ag-grade-widths-drilling-inte Publisher: tmx Original announcement: 2026-09-08T10:00:00.000Z Analysis by Minestarters Atlas Atlas analysis published: Unknown date Atlas analysis updated: Unknown date - Company: Marimaca Copper Corp. - Ticker: MARI - Exchange: TSX - Region: Chile's Antofagasta Region - Primary commodity: Copper - Secondary commodities: Silver - Document categories: Drill results - Extracted: 2026-09-14 10:24:00 UTC Narrative sentiment: 0.90 · Bullish ## Minestarters Atlas summary Marimaca Copper Corp. reported extraordinary copper-silver drill results from its Pampa Medina deposit in Chile, highlighted by hole SPRD-15 intersecting 216m of 0.96% Cu and 7.2g/t Ag, including 62m of 2.20% Cu and 21.5g/t Ag. Step-out drilling successfully extended the mineralized sedimentary horizon, confirming strong lateral and vertical continuity of the high-grade manto system. The company plans further exploration work, including geophysical surveys and additional drilling, to test extensions of the system. Reasoning: Marimaca Copper's drilling at Pampa Medina delivered exceptional copper grade-width products, including a bonanza intercept of 216m at 0.96% Cu and 7.2g/t Ag, with a high-grade core of 62m at 2.20% Cu and 21.5g/t Ag. These results extend mineralization and confirm strong continuity within the manto-style deposit. True widths are estimated, and comprehensive QA/QC procedures were disclosed, enhancing confidence. However, no cut-off grade was used for reporting, and metal equivalent assumptions were not provided. - Positive factor: Bonanza Intercept - Positive factor: True Width Disclosed - Positive factor: Step-Out Extension - Positive factor: QA/QC Disclosed - Positive factor: Continuity - Negative factor: Cut-off Undisclosed - Negative factor: Metal Equivalent Opaque - Negative factor: Silver Below Detection Limit Low confidence — this extraction should be reviewed alongside the original source.

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.
