Magna Terra Commences Exploration Program on the Great Northern and Viking Projects, Western Newfoundland

TORONTO, June 17, 2021 - Magna Terra Minerals Inc. (the "Company" or "Magna Terra") (TSXV:MTT) is pleased to announce that it has initiated a systematic exploration program (the "Exploration Program") at its 100% owned Great Northern and Viking Gold Projects ("Great Northern" and "Viking"), located in western Newfoundland. The Exploration Program is focused on follow-up prospecting and geological mapping of the numerous geochemical and geophysical anomalies generated at and near the 2.4-kilometre Jacksons Arm Trend and the Rattling Brook Deposit as outlined in the Company's news release dated February 4, 2021. In addition, the Company is collecting 2,500 soil samples along the strike extent of the Jackson's Arm Trend and the Rattling Brook Deposit, in order to determine the full strike length of anomalous gold-in-soil reflected in underlying gold bearing structures that may continue for an additional 2.2+ kilometres.

"We are excited to be starting our summer field program at Great Northern and Viking where our work will focus on following up on coincident IP chargeability, magnetic and soil geochemical anomalies at Jackson's Arm that were not tested in the Phase 1 drilling program completed in late 2020. Additionally, we are expanding our focus to other areas on the Property with high exploration potential including the collection of 2,500 soil samples along strike from the Jacksons Arm Trend and south of the Rattling Brook Deposit resource, as well as reconnaissance prospecting and geological mapping in the Little Davis Pond Area. This work will provide the information needed to finalize a Phase 2 drilling program at Great Northern scheduled for later this summer."

About the Great Northern and Viking Projects

The Great Northern and Viking Projects comprise two separate claim blocks (14,675 hectares) that are located near the communities of Sops Arm, Pollard's Point and Jackson's Arm, NL.

The Projects are centered along a 20-kilometre section of the Doucer's Valley Fault, a significant geological control on, and host to, several gold deposits and untested prospects, including the Rattling Brook and Thor Deposits, Jacksons Arm, Little Davis Pond, and Viking Trends and the Incinerator Trail Zone. Gold mineralization is hosted within a variety of rocks types that include Precambrian or Ordovician granites, or younger volcanic and sedimentary rocks, typically along splays off the Doucer's Valley Fault. Alteration consists of mesothermal style quartz ± iron carbonate ± sulfide veins and stockworks with 2 to 5% total sulfides consisting of pyrite, galena, chalcopyrite or sphalerite, and locally show trace amounts of visible gold.

Magna Terra is focussing on the Jacksons Arm Trend, which is host to a 2.4 kilometre long by 40- to 400-metre-wide continuous alteration zone, that is controlled by a north-south striking fault. The fault extends immediately to the north along strike with similar repeating fault zones to the east outlining a potential strike extent of an additional 4 kilometres. A recent phase 1 drilling (see news release dated February 18, 2021) by the Company at the Jacksons Arm Trend intersected broad zones of alteration and gold mineralization in each drill hole outlining a large fertile gold-bearing alteration system along at least a 300 metre section of the larger Jacksons Arm Trend with assays including:

• 4.67 grams per tonne ("g/t") gold over 0.5 metres (73.5 to 74.0 metres) in drill hole JA-20-01;
• 3.84 g/t gold over 0.5 metres (46.5 to 47.0 metres) in drill hole JA-20-07; and
• 2.01 g/t gold over 1.0 metres (22.5 to 23.5 metres) in drill hole JA-20-08.

Highlights of previous surface grab samples** include:

• Assays up to 20.20 g/t gold and 1,232 g/t silver at the Boot N' Hammer Prospect;
• Assays up to 56.70 g/t gold and 2.75 ounce per tonne silver at the Stocker Prospect;
• Assays up to 7.20 g/t gold at the Shrik Prospect; and
• Assays up to 13.60 g/t gold at the 954 Prospect.
  • An Inferred Mineral Resource Estimate^ of 5,460,000 tonnes at an average grade of 1.45 g/t gold containing 255,000 contained ounces at a cut-off grade of 1.0 g/t gold at the Rattling Brook Deposit; and

**Grab samples are selected samples and are not necessarily indicative of mineralization that may be hosted on the property.

The Little Davis Pond Trend is underlain by strongly deformed and altered Silurian volcanic and sedimentary rocks that are host to a 1.4-kilometre-long geochemical anomaly (soil assays up to 530 ppb gold, and rock assays up to 22.15 g/t gold) from historic sampling.

The Incinerator Trail Zone has been tested by four reconnaissance-style diamond drill holes in the 1980's and returned assays of 1.78 g/t gold over 4.0 metres (hole RB-35) and 2.30 g/t gold over 4.05 metres (hole RB-41).

The Viking Trend is host to a 3+ kilometre long by up to 40-metre-wide deformation and alteration zone with gold grades of 0.45 g/t gold over 20.0 metres in hole VK-16-151, 0.37 g/t gold over 16.5 metres in hole VK-11-125, as well as local high grades as indicated by 7.43 g/t gold over 1.0 metre in hole VK-16-155.

The Great Northern and Viking Projects are host to significant Current and Historic Mineral Resources, including:

• An Historical Indicated Mineral Resource^^ of 937,000 tonnes at an average grade of 2.09 g/t gold containing 63,000 ounces of gold plus an Historical Inferred Mineral Resource of 350,000 tonnes at an average grade of 1.79 g/t gold containing 20,000 ounces of gold at a cut-off grade of 1.0 g/t gold at the Thor Deposit.

Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability. All Mineral Resource Estimates were prepared in accordance with NI 43-101 and the CIM Standards (2014). Please refer to the NI 43-101 Technical Report with effective date January 23, 2019 by Harrington and Cullen (2019) as detailed below for the Great Northern Project and the NI 43-101 Technical Report with effective date August 29, 2016 by Copeland et al. (2016). An Independent Qualified Person has not carried out sufficient work to classify the Thor Historical Mineral Resource Estimate as current and Magna Terra is not considering this Mineral Resource Estimate to be current. Magna Terra considers the Thor Deposit to have potential for expansion that will be addressed by the Company in future exploration programs. See further details on Technical Reports below.
