TORONTO, ON / ACCESS Newswire / June 3, 2025 / Magna Terra Minerals Inc. ('Magna Terra' or the 'Company') (TSXV:MTT) is pleased to announce that it has commenced its inaugural exploration program at its 40,675-hectare, 100% owned Humber Copper-Cobalt Project (the 'Humber Project' or the 'Project') located in western Newfoundland (Figure 1). The Company has initiated a 2,377 line-kilometre ('km') airborne geophysical survey. The helicopter-borne survey will comprise a systematic, property-wide, time-domain electromagnetic ('VTEM™ Plus') and horizontal magnetic gradiometer survey and will provide the baseline geophysical data to guide geological mapping and focus exploration efforts to discover Copper-Cobalt deposits. This is the first geophysical survey of this type in the area. The Company is interested in areas of geophysical anomalies coincident with anomalous copper ('Cu'), cobalt ('Co'), lead ('Pb'), silver ('Ag'), molybdenum ('Mo'), gold ('Au'), arsenic ('As'), and antimony ('Sb') lake sediment values (Figures 1 and 2) found throughout the Project area including the Hughes Lake Trend where an 8 km long anomalous zone of copper and cobalt in soil samples is coincident with mafic volcanic rocks of the Hughes Lake Complex and associated magnetic rocks (Figures 3 and 4).
Humber Project Highlights
'Initiation of the airborne geophysical survey marks our inaugural exploration program at the Humber Project. This greenfields exploration project is host to numerous critical metal anomalies and has the geological environment consistent with the potential to host Sediment-hosted Stratiform Copper Deposits, which are globally significant producers of copper and cobalt with considerable by-products including rare and precious metals such as Mo, Ag, Au, U, REE, and PGEs. This geophysical survey is the first of its kind for this area and will provide the data to identify geophysical anomalies consistent with Stratiform Copper Deposits and will focus our field efforts on areas of coincident geophysical and geochemical anomalies. Building on the geophysical program, we anticipate commencing field work in the coming weeks as geophysical data begins to roll in with initial focus along the Hughes Lake Trend - an 8-km zone of copper-cobalt-in-soil anomalies adjacent to anomalous regional lake sediments.
At the Humber Copper-Cobalt Project, we have assembled a rare, first-mover, district-scale project opportunity, that will continue to leverage our expertise. We are eager to demonstrate the Project's prospectivity focused on critical metal discovery and the value we believe this Project brings to our investors.'

About the Geophysical Survey
The helicopter-borne survey is being completed by Geotech Ltd. and comprises a Versatile Time-Domain Electromagnetic (VTEM™ Plus) and horizontal magnetic gradiometer survey. The survey will be flown at 200 m spacing in a northwest trend across the strike of the underlying geology with perpendicular tie lines flown at 2 km spacing.
Lake Sediment Geochemistry and Global Analogues
The Project is underlain by rocks of the sedimentary 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 ppb). An analysis of the lake sediment geochemical data via 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-Ni values which precludes association with the nearby ophiolite complexes to the immediate west.
This metal signature (Cu, Co, Ag, Pb +/- Au, Mo, As, Sb) and geological environment is supportive of the area being host to SSC Deposits. SSC Deposits host 60% of global Cobalt production^ and 20% 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% Cu)* and large resources of by-product Au, U, 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.
