Magna Terra Minerals Inc. (TSXV: MTT) ("Magna Terra" or the "Company") is pleased to announce that it has discovered copper mineralization during early-stage prospecting at its 40,675-hectare, 100% owned Humber Copper-Cobalt Project (the "Humber Project" or the "Project") located in western Newfoundland (Figure 1). The discovery of copper mineralization in bedrock is located on the east end of the Hughes Lake Trend. Copper mineralization from surface rock grab samples^^ from outcrop and subcrop comprises between 0.5 to 5% combined, fracture-controlled, foliation parallel stringers and disseminated, malachite, bornite and chalcopyrite hosted within dolomitized limestone and adjacent altered clastic sedimentary and/or mafic volcanic rocks over an observed strike length of 700 metres and marks the first occurrence of copper noted on this under-explored property (Figures 1, 2, and 3). Ongoing and initial field work consisting of prospecting, geological mapping, and the collection of 1,700 soil samples is focused on following up on the Hughes Lake Trend where an 8-kilometre-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.
All soil and rock samples collected will be submitted to Eastern Analytical Ltd. in Springdale, NL and will be analysed for gold (30 g fire assay) and multi-element geochemistry, including elements Cu, Pb, Zn, Co, and Ag (method ICP-34). Analytical results are pending and will be reported in a future news release.
The Company is also pleased to announce that it has completed the previously announced 2,377 line-kilometre ("km") airborne geophysical survey on the Project. The helicopter-borne survey consisted of 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 assist in focusing exploration efforts on the discovery of 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 found throughout the Project area (Figures 1 and 2).
Magna Terra would like to acknowledge and thank both the Province of Newfoundland and Labrador and the Atlantic Canada Opportunities Agency ("ACOA") for their financial assistance through Junior Exploration Assistance ("JEA") program for work on the Humber Copper-Cobalt Project.
"We are very encouraged to have discovered in-situ copper mineralization within the first few days of working on the Humber Project. This important discovery supports our concept that the Humber Project has the potential to host Sediment-hosted Stratiform Copper Deposits, and with our exploration team currently on the ground we look forward to assessing additional targets across the extensive property. With the completion of the airborne survey, we will have one of the requisite data layers upon which to base further targeting for similar style mineralization. We look forward to updating shareholders on the results of this initial work program and sincerely appreciate the financial support of the Province of Newfoundland and Labrador and ACOA through the JEA program.
"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."

Humber Project Highlights
- Potential for discovery of significant Cu-Co deposits;
- Host to regionally anomalous Cu, Co, Ag, Pb +/- Au, Mo, As, and Sb lake sediments;
- 8+ km Hughes Lake Copper-Cobalt Trend;
- Analogous to the Kalahari Copper Belt, Namibia and Botswana; Central African Copper Belt, Zambia and the Democratic Republic of Congo (DRC); and the Kupferschiefer Belt, Poland;
- Globally, these Sediment-hosted Stratiform Copper ("SSC") deposit types represent 20% of Cu production* and 60% of Co production^;
- District-scale land package now comprising 40,675 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 - cost effective acquisition and with no underlying royalties or option payments.
About the Geophysical Survey
The helicopter-borne survey was completed by Geotech Ltd. and comprised a Versatile Time-Domain Electromagnetic (VTEM™ Plus) and horizontal magnetic gradiometer survey. The survey was flown at 200 metre spacing in a northwest trend across the strike of the underlying geology with perpendicular tie lines flown at 2 kilometre 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.
