Northern Shield Increases Land Position to 420 km² Covering Multiple Porphyry Copper & Epithermal Gold Targets In Newfoundland

OTTAWA, ON, Feb. 27, 2026 /CNW/ - Northern Shield Resources Inc. ("Northern Shield" or the "Company") (TSXV: NRN) is pleased to announce that through map staking, option agreements and property purchase, the Company has increased its land position from 32 km² to 420 km² pursuant to definitive agreements entered into with arm's length parties on February 18, 2026 (collectively, the "Definitive Agreements"). The Company's flagship Root & Cellar Gold-Silver-Tellurium-Copper Property ("Root & Cellar" or the "Property"), on the Burin Peninsula in southeastern Newfoundland, forms the core of the land position. Recent work at Root & Cellar, suggests a large, diatreme/porphyry-hosted, polymetallic Cu-Au-Ag-Te-Mo zone, which was the impetus for the land acquisitions in the Avalon Zone of eastern Newfoundland.

The most significant of these new properties is the 212 km² Fortune Property (Figure 1) composed of two property options totalling 65 km², with the remainder having been map staked directly by Northern Shield. The Fortune Property covers a 40 km trend that is highly prospective for porphyry copper and epithermal gold systems, and includes multiple indications of such systems including 4 known occurrences:

Stewart: The Stewart prospect represents the most aerially extensive and continuous zone of exposed alteration on the Burin Peninsula, reaching widths of up to 850 m and extending along strike for upwards of 4 km (Figure 2a). It represents an extensive zone of advanced argillic alteration including pyrophyllite, alunite and vuggy quartz, interpreted to be a lithocap to a porphyry Cu-Mo-Au system. The lithocap is anomalous in gold, copper and molybdenum over significant intervals including historical surface trenching results of 0.09 g/t Au over 219 m, (Dyke, B., 2008,) and a drill intercept of 0.13 g/t Au over 111 m (Setterfield, T., 2016,) along with anomalous Cu and Mo.

Forty Creek: The Forty Creek intermediate sulphidation quartz vein is along strike from Stewart and hosts gold and silver tellurides with values up to 59 g/t Au and 2,290 g/t Ag (Setterfield, T. 2011). (Figure 2b) and grab samples with values to 0.16% Cu and 0.1 g/t Au in a nearby silicified pyrophyllite alteration zone.

Point Rosie: Hosts multiple quartz-sericite-pyrite (phyllic) alteration zones consistent with epithermal and porphyry copper systems over a 4 km strike length. Copper-gold-silver anomalous quartz veins (Figure 2c) with values up to 0.67 g/t Au and 0.65% Cu (Noel, N., 2020) have recently been discovered within a 2.5 km gold-in-soil anomaly.

Feeder Brook: Hosts multiple quartz-sericite-pyrite alteration zones with grab samples values to 0.9 g/t Au (Dimmell, P., 2003). Nearby till samples collected by the Geological Survey of Newfoundland and Labrador are anomalous in porphyry copper pathfinder elements.

Some of the assay certificates for the results mentioned have been reviewed by Northern Shield while others have not, and Northern Shield is relying on third party assessment reports filed with the Newfoundland and Labrador government for the values quoted. None of the samples were collected or assayed by Northern Shield and hence cannot be fully and independently verified by the Company.

The Company has also acquired 3 claim groups totalling 136 km² on the Cape St Mary's Peninsula across Placentia Bay from Root & Cellar. The primary target is a porphyry copper system similar to Root & Cellar based on Cu and Mo anomalous till samples reported by the Geological Survey of Newfoundland and Labrador and description of "malachite-stained quartz stockwork veining" in the government's mineral occurrence database. Some of the tills are also highly anomalous in nickel and cobalt and since gabbroic rocks are reported from the area, the claims will also be targeted for magmatic Ni-Cu-Co sulphides.

"We are very excited about these new land positions. We see growing interest in the porphyry copper potential of the Burin Peninsula as we uncover more mineralization at the Creston Copper Target. As such these new properties cement our "first mover status" and allow us to use the knowledge we have gained from Root & Cellar to our advantage. We haven't just amalgamated a prospective land position but amalgamated, incentivized, and mobilised some of the most experienced and tenacious prospectors in the region. They are our first asset and, collectively, have seen more rocks on the Burin than anybody. I have little doubt that they will have success in finding new mineralization in the spring."

About Northern Shield Resources

Northern Shield Resources Inc. is a Canadian-based company, a leader in generating high-quality exploration targets, that views greenfield exploration as an opportunity to find a mineable, near surface deposit at relatively low cost. We implement a model driven exploration approach to reduce the risk associated with early-stage projects for ourselves, our shareholders, and the environment. This approach led us to option the Root & Cellar Property from a Newfoundland prospector, who discovered the copper mineralization, and then to its advancement to the large gold-silver-tellurium and porphyry copper system that it has become.
