MAGNA TERRA EXTENDS GEOCHEMICAL ANOMALY TO 4.2 KILOMETRES AT THE BIRCH ZONE ON THE HUMBER COPPER-COBALT PROJECT, NEWFOUNDLAND

Magna Terra Minerals Inc. has received an additional 1,084 analytical results from an expanded soil geochemical survey over the 100-per-cent-owned Humber copper-cobalt project located in western Newfoundland (see news release dated Nov. 18, 2025). The 1,084 soil samples were collected to the south, southwest and northeast of the 2.2-kilometre-long Birch zone, a zone of outcropping copper mineralization that is coincident with a linear magnetic low signature from the recently completed airborne geophysical survey covering the property. The additional soil sampling was designed to expand the strike potential of the Birch zone where rock sampling in 2025 resulted in copper assays of up to 1.26 per cent copper.

These results, combined with previous soil sampling (837 samples in news release dated Nov. 18, 2025), have expanded the geochemical footprint of the Birch zone to a potential strike extent of 4.2 kilometres. The copper-cobalt trend is spatially coincident with a magnetic low outlined in the recently completed airborne VTEM survey (see news release dated Sept. 18, 2025). Based on the airborne magnetics, there is three kilometres of additional untested strike extent to the southwest.

The 1,084 soil samples were collected over a 5.0-kilometre strike length at 200-metre line spacing and 25-metre sample spacing. Grid lines were oriented northwest-southeast, perpendicular to northeast-southwest-trending magnetic anomalies and stratigraphy. The soil samples were analyzed at Eastern Analytical Ltd. in Springdale, Nfld., for gold and multielement ICP analysis. Of the 1,084 samples collected over the Birch zone, copper values range between less than five parts per million (below detection) and 1,130 ppm Cu with 25 of 1,084 (2.3 per cent) assaying over 50 ppm; cobalt values range between less than two ppm (below detection) and 100 ppm Co with 58 of 1,084 (5.4 per cent) assaying over 20 ppm.

Humber project highlights:

• Discovery of 2.2 kilometres of surface copper mineralization at the Birch zone, with potential to expand to 4.2 kilometres based on geochemistry and geophysics;
• Host to regionally anomalous copper, cobalt, silver and lead plus or minus gold, molybdenum, arsenic and antimony lake sediments;
• Airborne conductors coincident with lake and stream sediment Cu and Co anomalies;
• Eight-plus-kilometre Hughes Lake copper-cobalt trend;
• Analogous to the Kalahari copper belt, Namibia and Botswana; Central African copper belt, Zambia and the Democratic Republic of the Congo; and the Kupferschiefer belt, Poland;
• Globally, these sediment-hosted stratiform copper deposit types represent 20 per cent of Cu production and 60 per cent of Co production;
• District-scale land package now comprising 49,925 hectares;
• Located within the premier mining jurisdiction of Newfoundland and Labrador;
• Year-round accessibility with road access to the majority of the project;
• First-mover advantage in a previously unrecognized area of exploration potential; and
• Acquired through staking, through cost-effective acquisition, and with no underlying royalties or option payments.

"The results of this additional soil sampling program continue to progress what is becoming a very exciting and potentially significant discovery zone, that we now refer to as the Birch zone. The elevated Cu and Co in soil samples and their coincidence with a magnetic low is suggestive that the Birch zone can be extended by an additional two kilometres to a potential minimum strike length of 4.2 kilometres. The strong correlation between the surface geochemical signature and magnetic low is very encouraging as the magnetics indicate a further potential strike extension of the Birch zone a minimum of three kilometres to the southwest. These results support our exploration approach on the Humber project where we continue to outline new targets and make discoveries via a combination of traditional boot and hammer prospecting, soil and stream sediment geochemical sampling, and airborne geophysics. We are excited to follow up in the coming weeks on these most recent soil sample results and the recently announced property-scale stream sediment anomalies. The company is actively planning our exploration programs for the remainder of the year on the Humber, Rocky Brook and Prospect Or's Dream projects," said Lew Lawrick, president and chief executive officer, Magna Terra.

Lake sediment geochemistry and global analogues

The project is underlain by sedimentary rocks of the Humber Arm allochthon and adjacent plutonic and volcanic Hughes Lake complex, which is centred on a series of anomalous lake sediment samples (Davenport et al., 1996) that show regionally elevated levels of Co (up to 160 ppm), Ag (up to 0.6 ppm), Pb (up to 84 ppm), Cu (up to 185 ppm), As (up to 142 ppm), Mo (up to 15 ppm) and Au (up to 10 parts per billion). An analysis of the lake sediment geochemical data through principal component analysis has indicated that the metal suite present within the project area is likely related to a black shale source as many of the anomalous lake sediments have low nickel values, which preclude association with the nearby ophiolite complexes to the immediate west.

This metal signature (Cu, Co, Ag and Pb plus or minus Au, Mo, As and Sb) and geological environment are supportive of the area being host to SSC deposits. SSC deposits host 60 per cent of global cobalt production and 20 per cent of global copper production in deposits such as the Central African copper belt, which is thought to be analogous to the geological setting of the Humber copper-cobalt project. SSC deposits are often laterally continuous along bedding and contain consistent grades (1.2 to 5 per cent Cu) and large resources of byproduct gold, uranium, platinum group and rare earth elements. The exploration potential is also underscored by the presence of base metal deposits nearby including the York Harbour and Daniels Harbour deposits located at lower stratigraphic levels of the region.

Qualified person and technical disclosure

All soil samples were collected systematically every 25 metres along grid lines using hand-held GPS by contractor GeoXplore Surveys Ltd. out of Bathurst, N.B. The soil samples were submitted to Eastern Analytical Ltd. in Springdale, Nfld., and analyzed for gold (30-gram fire assay) and multielement geochemistry, including elements Cu, Co, Pb, zinc and silver (method ICP-34).

All quoted historic soil and lake sediment samples results were compiled from assessment and government reports obtained from the government of Newfoundland and Labrador. The qualified person has not completed sufficient work to validate these historic results.
