TORONTO — Magna Terra Minerals Inc. disclosed results from a regional stream sediment geochemical survey on its wholly owned Humber Copper-Cobalt Project. The survey covered 68% of the 49,925-hectare property in western Newfoundland. Company officials said the data points to strong potential for sediment-hosted stratiform copper mineralization.

Teams collected the 189 samples in summer 2025 from streams accessible by road across Blocks 1 and 2. Cobalt levels hit as high as 409 parts per million, with 10 samples exceeding 94.6 ppm. Copper reached 70 ppm, and nine samples topped 30 ppm. Lead peaked at 81 ppm, zinc at 617 ppm. Nine samples each surpassed 39 ppm lead and 220 ppm zinc.

Officials noted the strongest clusters in Block 1’s northwestern quadrant. Those spots match conductive shale and slate sequences detected in a September 2025 airborne geophysical survey. They also coincide with cobalt-rich lake sediments that prompted the project’s staking.

“These results continue to generate multiple coincident geochemical and geophysical targets,” President and CEO Lew Lawrick said. He highlighted zones of copper-cobalt mineralization beyond the initial Hughes Lake discovery. Magna Terra plans to extend the survey over the remaining area this spring.

The company also awaits assays from 821 soil samples taken along strike from a 2.2-kilometer surface copper zone at Hughes Lake. That trend holds potential for another 1.7 kilometers of extent. Lawrick called the stream data’s strong metal tenor a boost for sediment-hosted stratiform copper deposits, which supply 20% of global copper and 60% of cobalt output.

Humber sits in the Humber Arm Allochthon amid sedimentary rocks, plutonic and volcanic units of the Hughes Lake Complex. Historical lake sediments from 1996 show elevated cobalt up to 160 ppm, silver to 0.6 ppm, lead to 84 ppm, copper to 185 ppm, arsenic to 142 ppm, molybdenum to 15 ppm and gold to 10 ppb. Principal component analysis links the metal suite to black shale sources, not nearby ophiolites.

Geological parallels include the Kalahari Copper Belt in Namibia and Botswana, Central African Copper Belt in Zambia and the Democratic Republic of Congo, and Poland’s Kupferschiefer Belt. Such deposits often run 1.2% to 5% copper with byproducts like gold, uranium, platinum-group elements and rare earths. Nearby base metal sites such as York Harbour and Daniels Harbour add to the district’s promise.

Magna Terra secured the land through staking at low cost, free of royalties or payments. Road access supports year-round work in Newfoundland and Labrador, a top mining jurisdiction. David A. Copeland, P.Geo., a consultant and qualified person under National Instrument 43-101, reviewed and approved the release. Contractor GeoXplore Surveys gathered samples, sieved to 2 mm and analyzed at Eastern Analytical Ltd. in Springdale, Newfoundland, via fire assay for gold and ICP-34 for multi-elements.

Historical soil and lake data came from government reports. Copeland has not verified those results. Grab samples remain selective and unrepresentative.
