Breaking News: Unlocking the Potential of the Humber Project!
Toronto, Ontario, November 18, 2025 - Magna Terra Minerals Inc. (TSXV: MTT) has some exciting news to share about their Humber Copper-Cobalt Project. The recent soil survey results have indicated a potential treasure trove of mineralization, with a minimum estimated extension of 1.7 kilometers along the strike. But here's where it gets controversial...
The soil sampling, an extensive process involving 837 samples across the property, revealed copper values ranging from <5 ppm to an impressive 2,150 ppm Cu. What's more, 5.5% of these samples assayed over 500 ppm, suggesting a significant concentration of copper. This discovery has led to the expansion of the known mineralized zone to 2.2 kilometers, and there's more!
The survey also hints at the possibility of extending this mineralized zone by a further 1.7 kilometers to the southwest, where historical data shows elevated copper levels in soils along a magnetic low. This potential extension is a game-changer and could significantly impact the project's overall value.
Furthermore, the infill and expansion soil sampling over the mafic volcanic unit continue to showcase elevated copper values, indicating the larger Hughes Lake Trend's potential to host undiscovered copper mineralization.
And this is the part most people miss: the copper mineralization is hosted within dolomitized limestone, with visible copper minerals ranging from trace amounts to a remarkable 5% combined chalcopyrite, bornite, and malachite.
Magna Terra is grateful for the financial support received from the Province of Newfoundland and Labrador and the Atlantic Canada Opportunities Agency (ACOA) through the Junior Exploration Assistance (JEA) program. This assistance has been instrumental in advancing the Humber Copper-Cobalt Project.
The project's highlights include:
- Discovery of a 2.2-kilometer-long surface copper mineralization at Hughes Lake, with the potential for an additional minimum 1.7 kilometers of strike extent.
- Host to regionally anomalous levels of Cu, Co, Ag, Pb, Au, Mo, As, and Sb in lake sediments.
- Airborne conductors coincident with these lake sediment anomalies.
- An extensive 8-kilometer Hughes Lake Copper-Cobalt Trend.
- Analogous to globally significant copper belts in Namibia, Botswana, Zambia, and the Democratic Republic of Congo (DRC), as well as the Kupferschiefer Belt in Poland.
- Sediment-hosted Stratiform Copper (SSC) deposits, which represent 20% of global Cu production and a whopping 60% of global Co production.
- A district-scale land package comprising a massive 49,925 hectares.
- Located in the premier mining jurisdiction of Newfoundland and Labrador, with year-round accessibility and road access to most of the project.
- First-mover advantage in an area with unexplored potential.
- Acquired through staking, ensuring a cost-effective acquisition with no underlying royalties or option payments.
Lew Lawrick, President, and CEO of Magna Terra Minerals Inc., commented on the results: "We are thrilled with our systematic work at Humber so far. The extension of the copper mineralization zone to 2.2 kilometers, now confirmed by assay results, is a testament to the project's near-term discovery potential. Soil sampling has proven to be an effective exploration tool in this geological domain, and we are excited to continue our work to uncover more targets and zones of copper-cobalt-silver mineralization on the broader property package."
The project's geological setting, underlain by the sedimentary Humber Arm Allochthon and the adjacent plutonic and volcanic Hughes Lake Complex, is centered around a series of anomalous lake sediment samples. These samples exhibit elevated levels of Co, Ag, Pb, Cu, As, Mo, and Au, indicating a black shale source and supporting the potential for SSC deposits.
SSC deposits are globally significant, hosting a substantial portion of global Cobalt and Copper production. They are often laterally continuous along bedding, with consistent grades and large resources of by-product elements such as Au, U, platinum-group, and rare-earth elements. The presence of nearby base metal deposits, including the York Harbour and Daniels Harbour Deposits, further underscores the exploration potential of the Humber Project.
The Qualified Person, David A. Copeland, P.Geo., has reviewed and approved this news release. All samples collected from the current fieldwork were analyzed by Eastern Analytical Ltd. in Springdale, NL, for gold and multi-element geochemistry, including Cu, Pb, Zn, Co, and Ag.
Grab samples, while selective in nature, may not accurately represent the true metal content of the mineralized zone.
