Magna Terra extends copper mineralization at Humber

Executive Summary

• Magna Terra Minerals Inc. has extended the surface zone of copper mineralization at its Humber Copper-Cobalt Project in Newfoundland to a total strike length of 2.2 kilometres, following prospecting and geological mapping completed in the fall.
• The company has initiated a regional stream silt geochemical sampling program to define priority targets, complementing a recently completed airborne geophysical survey.
• Visible copper mineralization (trace to 5% combined chalcopyrite, bornite, and malachite) was observed in 57 rock grab samples, with assay results currently pending.

Key Details

• Mineralization Extension: The surface extent of copper mineralized, dolomitized limestone along the Hughes Lake trend was extended by an additional 1.2 kilometres to the east, bringing the total strike extent to 2.2 kilometres.
• Sampling Results: A total of 57 rock grab samples were collected. Visible copper mineralization ranging from trace to 5% combined chalcopyrite, bornite, and malachite was noted. Assays are pending.
• New Exploration Activity: Commenced a program of regional stream silt geochemical sampling on the greater project area.
• Geophysical Context: The geochemical sampling aims to define priority targets in areas of elevated electromagnetic conductance, following a recently completed airborne geophysical survey (referenced in a Sept 18, 2025 release).
• Lake Sediment Geochemistry: The project area shows regionally anomalous levels in lake sediments, including:
  • Cobalt (Co): up to 160 ppm
  • Silver (Ag): up to 0.6 ppm
  • Lead (Pb): up to 84 ppm
  • Copper (Cu): up to 185 ppm
  • Arsenic (As): up to 142 ppm
  • Molybdenum (Mo): up to 15 ppm
  • Gold (Au): up to 10 ppb
• Geological Analogue: The metal signature and geological environment support the potential for Sediment-Hosted Stratiform Copper (SSC) deposits, analogous to the Central African copper belt, Namibia/Botswana, and the Kupferschiefer belt. SSC deposits account for 60% of global cobalt production and 20% of global copper production.
• Project Scale: The district-scale land package comprises 49,925 hectares.
• Funding: Acknowledged financial assistance from the province of Newfoundland and Labrador and the Atlantic Canada Opportunities Agency (ACOA) through the Junior Exploration Assistance (JEA) program.
• Analytical Methods: Samples submitted to Eastern Analytical Ltd. for gold (30 g fire assay) and multielement geochemistry (ICP-34) including Cu, Pb, Zn, Co, and Ag.

Notable Quotes

• "The rapid growth of the surface strike extent of copper mineralization within the Hughes Lake copper zone so early into our exploration efforts, is a very exciting development for Magna Terra and its shareholders and certainly bodes well as we expand our systematic generative exploration efforts over the expansive project area." — Lew Lawrick, President and CEO
