MAGNA TERRA COMMENCES EXPLORATION AT THE HUMBER AND SHELLBIRD PROJECTS, NEWFOUNDLAND

Magna Terra Minerals Inc. has commenced its summer exploration programs at the Humber copper-cobalt and Shellbird gold projects, located in western Newfoundland. The work, part of a phase 1 2026 exploration program, at Humber is designed to follow-up on a successful initial exploration program in 2025 that resulted in the discovery of the 2.2-kilometre Birch zone, as well as the identification of several high-priority combined geophysical and geochemical (copper, cobalt) targets for follow-up prospecting. The initial work at Shellbird will focus on prospecting and geological mapping at this recently acquired gold project.

The planned phase 1 exploration program includes the following.

Humber copper-cobalt project:

• Prospecting to extend the Birch zone along strike, where soil sampling and geophysics from 2025 suggest potential for 2.0-plus kilometres of additional strike length;
• 1,000 soil samples to test additional three kilometres extent southwest of Birch zone;
• Prospecting of copper and cobalt stream sediment anomalies coincident with airborne geophysical conductors identified in 2025;
• 300 stream sediment samples to complete coverage of the property in remote areas not sampled in 2025.

Shellbird gold project:

• Initial prospecting and geological mapping of the 2.33-gram-per-tonne-gold (g/t) sample collected in 1997;
• 75 stream sediment samples to follow up on gold grains identified in historic stream sediment sampling.

"In addition to our exploration efforts on our priority projects in northern New Brunswick that commenced two weeks ago, we are eager to initiate phase 1 exploration activities on our priority projects within our Newfoundland portfolio. Phase 1 work at the Humber project will focus on expanding the strike extent of the Birch zone Cu discovery, follow-up on the regional geophysical and geochemical targets generated in 2025, and look to complete stream sediment geochemical coverage of the entire property. This systematic approach at Humber will help to further identify the scale of copper mineralization at the Birch zone, as well as identify other zones of potential copper-cobalt mineralization within the greater project area.

"At Shellbird, we are eager to get our first 'boots on the ground' on the project and follow up on the historical rock sample results from 1997 within this very underexplored area. This early-stage opportunity, much like the Humber project, was identified by our technical team and provides shareholders with exposure to another district-scale, low-cost land package that we will look to advance through systematic exploration. The Shellbird gold project is located along a mineralized trend that our team has a deep understanding of, as it lies along the projection of the regional-scale Doucer's Valley fault zone (DVFZ), which is host to the company's Great Northern and Viking gold project currently under option to Gold Hunter Resources (HUNT). HUNT is finalizing details associated with a planned 10,000-metre drill program, set to launch in the coming weeks at the expanded Great Northern project. As the largest shareholder of HUNT, we are excited to see drilling get underway, which will generate significant additional news flow and is a further potential catalyst for our shareholders through 2026 into 2027," stated Lew Lawrick, president and chief executive officer, Magna Terra Minerals.

Humber copper-cobalt project highlights:

• 2025 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 a further 3.0 kilometres based on underlying geophysics;
• Host to regionally anomalous Cu (copper), Co (cobalt), Ag (silver), Pb (lead) plus or minus Au (gold), Mo (molybdenum), As (arsenic) and Sb (antimony) lake sediments;
• Airborne geophysical 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 (DRC); and the Kupferschiefer belt, Poland;
• Globally, these sediment-hosted stratiform copper (SSC) 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;
• Acquired through staking -- cost-effective acquisition and with no underlying royalties or option payments.

Shellbird gold project highlights:

• The project covers a 35-kilometre extent of the regional-scale Doucer's Valley fault zone and associated fault splays;
• Strategically positioned 30 kilometres along strike from the Great Northern gold project in the same geological environment known to host orogenic gold mineralization;
• Historical (circa 1997) rock grab samples* from grassroots prospecting assaying up to 2.33 g/t gold with no follow-up;
• Government lake sediment samples with assays up to nine parts per billion (ppb) gold marking a strong regional geochemical anomaly;
• Historical stream sediment samples identified five locations with one gold grain in each sample (two pristine, two reshaped and one modified) at the southwest end of property;
• Large land package comprising 30,650 hectares;
• Largely road accessible and 10 kilometres north of the town of Deer Lake;
• Located adjacent to the Magna Terra's Humber copper-cobalt project, providing operational efficiencies.
