Pampa Medina Sulphide Drilling Intersects 16m of 5.70% Cu and 62.6 g/t Ag including 4m of 11.32% Cu and 144.0 g/t Ag in Significant Extension of UHG Bornite Zone

Marimaca Copper drilled ultra-high-grade bornite at Pampa Medina, though execution risk and capital intensity cap near-term upside.

Executive Summary
  • Marimaca Copper Corp. released assay results from its ongoing 2026 drilling program at the Pampa Medina deposit in Chile.
  • Hole SPRD-05 intersected 96m at 1.19% Cu and 11.7g/t Ag, including 60m at 1.80% Cu and 18.4g/t Ag, and 16m at 5.70% Cu and 62.6g/t Ag, including 4m at 11.32% Cu and 144.0g/t Ag.
  • The company is finalizing a 150m-spaced delineation campaign ahead of a maiden Mineral Resource Estimate (MRE).
  • Geophysical programs (AMT) were completed at Pampa Norte and Sierra Norte to identify continuations of favorable mineralized sedimentary units.
  • Management emphasized the strong lateral continuity of sulphide mantos and the deposit's potential for district-scale significance.
Material Impact
  • The June 8, 2026 release is a routine exploration update that follows a consistent series of high-grade copper-silver intercepts announced throughout 2025 and early 2026.
  • Results are fully in line with the company's stated 2026 exploration plan and previous announcements (May 19, April 2, March 11, January 26).
  • No new strategic partnerships, financing closings, permitting milestones, or resource estimates are disclosed in this release.
  • The market has already priced in the geological potential of Pampa Medina based on prior step-out drilling. This update merely confirms the continuity of the mineralized system.
  • Consequently, the news is incremental and expected, lacking the catalysts required to materially shift the stock's valuation or near-term trajectory.

Company Overview
  • Marimaca Copper Corp. is focused on the Marimaca Oxide Deposit (MOD) in the Antofagasta region of Chile.
  • The MOD is an IOCG-type copper deposit with a Definitive Feasibility Study (DFS) completed in August 2025.
  • The project targets 50 ktpa of copper cathode production over a 13-year mine life, with pre-production capital of US$587 million.
  • Economic metrics from the DFS show a post-tax NPV of US$709 million at $4.30/lb Cu and an IRR of 31%.
  • Pampa Medina is a separate sediment-hosted copper-silver manto system located ~28 km east of MOD, currently in the exploration and delineation phase.
  • The company aims to reach a Final Investment Decision (FID) in the second half of 2026.
