Magna Terra completes trenching at Fossil Hill zone

Executive Summary

• Magna Terra Minerals Inc. completed a trenching program at the Fossil Hill zone of its Rocky Brook project in New Brunswick, confirming significant copper mineralization in bedrock.
• Three trenches (T4, T7, and T8) totaling 245 meters in length exposed 192 meters of bedrock, with in-situ copper mineralization observed in all trenches, including a 40-meter zone in T8.
• The company has submitted 93 samples (grab, float, and channel) for analysis at ALS Canada Ltd., with results pending for gold and multielement geochemistry (Cu, Pb, Zn, Co, Ag).

Key Details

• Trenching Program: Completed three trenches (T4, T7, T8) totaling 245 meters in length, exposing 192 meters of bedrock.
• Mineralization Observations:
  • Trench T8: Exposed a 40-meter zone of copper mineralization (true width unknown).
  • Trench T4: Exposed variable, fracture-hosted malachite over 45 meters (true width unknown).
  • Trench T7: Exposed variable, fracture-hosted malachite over 40 meters (true width unknown).
• Historical Context: Trenching targeted historical grab samples that previously assayed up to 16.65% copper and 0.64% cobalt.
• Geology: Trenches exposed massive mafic volcanic and mafic volcanic breccia rocks of the Armstrong formation, Sormany Group.
• Mineralogy: Mineralization consists of malachite, chalcopyrite, and one local occurrence containing native copper, azurite, and possibly tenorite. Copper minerals are dominantly hosted in calcite-quartz veins and along fractures.
• Sampling:
  • 93 samples collected: 68 grab samples of bedrock (1-3m intervals), 11 grab samples of float, and 14 channel samples (0.1-1.0m length).
  • Samples submitted to ALS Canada Ltd. in Moncton, N.B.
  • Analysis methods: Gold (AU-AA23) and multielement geochemistry including Cu, Pb, Zn, Co, and Ag (ME-ICP41/ME-ICP61).
  • Status: Analytical results are pending and will be reported in a future news release.
• Project Highlights (Rocky Brook):
  • Covers a 40 km extent of favorable California Lake felsic volcanic and sedimentary rocks.
  • Identifies the 15 km Boudreau Brook-Fossil Hill trend of coincident geochemical and geophysical anomalies.
  • Located in the Bathurst Mining Camp (BMC), adjacent to Canadian Copper Inc.'s Caribou mill complex and Kinross-Puma's Lynx zone.
  • Covers Restigouche C-4 and C-5 footwall Cu-rich feeder zones with historical drilling intersections (e.g., C-4: 4.36m @ 0.2% Cu, 1.6% Pb, 6.74% Zn; C-5: 4.5m @ 2.06% Cu, 0.57% Zn).
  • Recent 2023 discovery of high-grade gold grab samples up to 5.23 g/t Au over a 350m strike length at Fournier Lake.
• Company Status: Magna Terra holds 28,089 hectares in 70 mineral claims for the Rocky Brook project. Work was partially funded by the New Brunswick junior mining assistance program (NBJMAP).

Notable Quotes

• "We are very excited with the results of our first trenching program on the Rocky Brook project. The spectacular samples of visible copper mineralization in the trenches confirms the results of historic rock grab sampling on the project." — Lew Lawrick, President and CEO, Magna Terra Minerals.
• "The proximity of this zone to Canadian Copper's Caribou mill complex adds a compelling narrative for the potential to identify and delineate additional copper-rich massive sulphide deposits well within economic trucking distance to the Caribou mill complex." — Lew Lawrick, President and CEO, Magna Terra Minerals.
