Magna Terra samples up to 1.2% Cu, 2.8 g/t Ag at Humber

Executive Summary

• Magna Terra reported initial rock‑sample assays from its newly discovered copper zone at the Humber Copper‑Cobalt Project, with copper grades up to 1.26 % Cu and silver up to 2.8 g/t Ag.
• Surface mineralization has been expanded to a minimum strike length of 1 km, and the company has added 112 new claims (2,800 ha), bringing the total project footprint to 43,475 ha.
• The results support the company’s hypothesis that Humber could host sediment‑hosted stratiform copper deposits analogous to world‑class districts, prompting further work including airborne magnetic/EM surveys and regional soil sampling.

Key Details

• Assay Program: 61 rock samples collected; 5 rushed for immediate analysis – Cu range 0.07 %–1.26 %, Ag range 0.2–2.8 g/t. Remaining 56 samples pending.
• Mineralization Description: Bedrock copper stringers/disseminations (malachite, bornite, chalcopyrite) within dolomitized limestone and altered clastic rocks; grades 0.5 %–5 % Cu in fracture‑controlled zones.
• Project Expansion: Additional 112 mineral licences (2,800 ha) acquired adjacent to Humber; total area now 43,475 ha.
• Geochemical Context: Historic lake‑sediment data show anomalous Co (up to 160 ppm), Ag (0.6 ppm), Pb (84 ppm), Cu (185 ppm), As (142 ppm), Mo (15 ppm), Au (10 ppb). PCA suggests a black‑shale source, supporting SSC deposit model.
• Analogous Deposits: Compared to Kalahari copper belt (Namibia/Botswana), Central African Copper Belt (Zambia/DRC), and Kupferschiefer (Poland); SSC deposits account for ~20 % of global Cu and ~60 % of Co production.
• Future Work Planned: Regional airborne magnetic & electromagnetic survey; expanded regional soil sampling program.
• Financial Assistance Acknowledged: Junior Exploration Assistance Program funding from the Province of Newfoundland and Labrador and the Atlantic Canada Opportunities Agency.
• Qualified Person: David A. Copeland, P.Geo., non‑independent consultant, NI 43‑101 qualified person.

Notable Quotes

“It is very encouraging to encounter surface copper values of up to 1.26 % Cu so early into the initial exploration program on the Humber project… This important discovery supports our concept that the Humber project has the potential to host sediment‑hosted stratiform copper deposits.” – Lew Lawrick, President & CEO, Magna Terra Minerals Inc.
