Humber Project Soil Survey Results Indicate Potential Minimum 1.7 KM of Surface Extension Along Strike

On November 18, 2025, Magna Terra Minerals announced results from a soil geochemical survey and additional rock grab sample assays for its Humber Copper-Cobalt Project in Newfoundland. The results confirmed the previously announced 2.2-kilometre surface copper mineralization trend at Hughes Lake. Key takeaways include: - Soil Survey: 837 samples were collected, with values ranging up to 2,150 ppm copper (0.215% Cu). 46 samples returned greater than 500 ppm copper. The survey indicates a potential minimum 1.7 km extension to the known mineralization along strike. - Rock Grab Samples: Assays from 57 rock grab samples returned values up to 5,452 ppm copper (0.545% Cu), with 17 samples assaying over 500 ppm copper. - Confirmation: The CEO stated that these assay results confirm the previously prospected 2.2-kilometre zone of copper mineralization.

This news is a material positive development, primarily because it provides analytical confirmation for the surface mineralization previously identified through prospecting (announced November 4, 2025) and expands the target area for future exploration. The systematic exploration approach is commendable and is successfully advancing the Humber project.

Tracing the project's evolution in 2025: - July 17: First discovery of in-situ copper over a 700-metre strike. - August 13: Initial high-grade assays up to 1.26% Cu from five grab samples; strike extended to 1.0 km. - September 18: More assays confirm the 1.0 km strike. - November 4: Visual prospecting extends the zone of surface mineralization to 2.2 km, with assays pending. - November 18 (Current News): The pending assays are reported, confirming the 2.2 km trend. Furthermore, a soil survey has identified an additional 1.7 km of strike potential.

While the results are encouraging for an early-stage project, a critical perspective is necessary. The reported grades (up to 0.545% Cu in selective grab samples and 0.215% Cu in soil) are anomalous and point to a mineralized system, but they do not guarantee economic viability. Grab samples are selective by nature and not representative of the overall grade. Soil geochemistry is a targeting tool, not a direct indicator of bedrock mineralization.

The true test for the Humber project will be drilling to determine the width, continuity, and grade of the mineralization at depth. This news successfully de-risks the project to the point where drill targets can be defined with higher confidence. It is a logical and positive step, but not a game-changing discovery in itself. The market has already priced in some success, with the stock moving from $0.02 to a high of $0.17 over the last year. This news validates that move but may not be enough to propel the stock significantly higher without a clear commitment to a drill program.

Magna Terra Minerals is a Canadian junior exploration company focused on acquiring and advancing mineral properties in Atlantic Canada and Argentina. The company operates as a project generator, often optioning its non-core assets to partners to generate non-dilutive funding while retaining exploration upside.

The company's current flagship project is the 100%-owned Humber Copper-Cobalt Project in western Newfoundland. It is a district-scale (49,925 hectares) grassroots exploration play targeting sediment-hosted stratiform copper (SSC) deposits, which are globally significant sources of copper and cobalt. Exploration in 2025 has rapidly advanced the project from a regional concept to a defined 2.2 km mineralized trend with an additional 1.7 km of potential strike, making it the company's primary value driver.
