Magna Terra identifies anomaly at Rocky Brook

Executive Summary

• Magna Terra Minerals Inc. released results from a reconnaissance soil geochemical program targeting the 4.2-kilometre-long footwall zone (Restigouche trend) of the Restigouche VMS deposit on its Rocky Brook project in New Brunswick.
• The program identified strong polymetallic anomalies (Cu, Zn, Pb, Au, Ag) spatially coincident with EM conductors and along strike from the Restigouche C-4 and C-5 footwall Cu-rich feeder zones.
• The company plans to complete gaps in the survey to the east and extend the grid to the south in the spring, aiming to delineate additional copper-rich massive sulphide deposits near the Caribou mill complex.

Key Details

• Sampling Program: 674 soil samples collected along a 3x1.5 km grid (200 m line spacing, 25 m sample spacing).
• Analysis: Samples analyzed at ALS Canada Ltd. for gold and multielement ICP analysis.
• Geochemical Results (95th Percentile, n=34):
  • Copper: >46 ppm (Range: 1–385 ppm)
  • Zinc: >276 ppm (Range: 5–546 ppm)
  • Lead: >179 ppm (Range: 4–722 ppm)
  • Gold: >0.029 ppm (Range: <0.005–0.186 ppm)
  • Silver: >0.6 ppm (Range: <0.2–2.6 ppm)
• Historical Context: Follow-up to 2025 prospecting which returned rock grab samples up to 8.17% Cu and 1.57% Zn from the C-5 footwall zone.
• Future Plans: Complete survey gaps to the east and extend grid to the south; advance high-priority targets on the Restigouche property (5–10 km southwest of Canadian Copper's Murray Brook deposit).
• Project Highlights:
  • Rocky Brook project covers 31,489 hectares in 75 mineral claims in the Bathurst Mining Camp.
  • Includes the Boudreau Brook-Fossil Hill trend (15 km long) with historic high-grade Cu-Co grab samples (up to 16.65% Cu, 0.64% Co).
  • Covers Restigouche C-4 and C-5 footwall feeder zones; historic drilling in C-4 intersected 4.36 m grading 0.2% Cu, 1.6% Pb, 6.74% Zn.
  • Located along strike from Kinross-Puma's Lynx zone gold discovery and adjacent to the Murray Brook deposit (largest undeveloped VMS in NB).

Notable Quotes

• "We are very pleased with the results of the reconnaissance soil geochemical program that indicates a strong polymetallic signature that is coincident with the C-4 and C-5 footwall zones at the Restigouche VMS deposit and also demonstrates strong signatures to the east towards Canadian Copper's Murray Brook deposit." — Lew Lawrick, President and CEO
