Northern Shield discovers at Fortune, completes geophysics at Root & Cellar

Northern Shield Announces New Discovery at Fortune and Completion of Geophysics at Root & Cellar, Newfoundland Canada NewsWire OTTAWA, ON , June 25, 2026 /CNW/ - Northern Shield Resources Inc.  ("Northern Shield" or the "Company" ) (TSXV: NRN) is pleased to provide updates on exploration at the Company's flagship Root & Cellar Property ( "Root & Cellar" ) and the Fortune Property ( "Fortune" ), both located on the Burin Peninsula of eastern Newfoundland.  The properties are being explored for porphyry copper ± molybdenum, gold and tellurium, and for epithermal gold-silver-tellurium. Fortune Property:  Recent prospecting in the Jasper Brook area of the Fortune Property (Fig 1) resulted in the discovery of epithermal-type mineralization with associated quartz veining and silicification.  The discoveries in outcrop and sub-crop include: Jasperoid hosting several phases of grey quartz veins, which host fine-grained pyrite with lesser chalcopyrite and bornite (Fig. 2a), which are cut by a later phase of crustiform-colloform banded quartz veins (Fig. 2b) also carrying fine-grained sulphides. Granular to breccia-textured quartz veins with significant coarse disseminated pyrite (Fig. 3a), with some hosting abundant bright green mica believed to be phengite or roscoelite (Fig. 3b).

Banded pyrite-silica along vein walls, with banded quartz-pyrite-chlorite infilling tension gashes (Fig. 4), locally cut by quartz-adularia(?)-pyrite veins. Grey, vuggy silica breccia containing pyrite and occasional grains believed to be fluorite (Fig. 5). Quartz-vein breccias (Fig. 6).

Larger quartz veins, some with minor chalcopyrite, bornite or trace covellite(?), and others with fine-grained molybdenite (Fig. 7). All mineral identifications described herein are preliminary, based on field and hand-specimen examination, and remain subject to laboratory confirmation.  Samples have been submitted for analyses with results pending. The discoveries were made by Root & Cellar discoverer Jeffery Brushett and veteran Burin prospector Albert Stone.

Alteration, consistent with porphyry copper and high-sulphidation gold systems, including silicification, pyrophyllite and alunite, was recognized in the Rattle Brook area previously, however the mineralization and veining in the Jasper Brook area is the first concrete indication of a mineral system in the area.   Prospecting follow up will continue in the Jasper Brook area to expand the mineralized area. "We are very excited about the rocks now emerging from Jasper Brook. The range of quartz textures and minerals points to a wide span of deposit styles and temperatures of formation — most likely a telescoped system in which deep, porphyry-proximal levels and shallower epithermal levels have been brought close together.

At this early stage it is hard to know exactly what we are dealing with, but having an abundance of mineralization is a good problem to have. We will be back in the Jasper Brook area in the coming days to expand the footprint of these discoveries and establish better context. These finds continue to emphasize the prospectivity and untapped potential of the Burin Peninsula for porphyry copper and epithermal gold,"   - Ian Bliss, President and CEO, Northern Shield Root & Cellar:  a 3D-IP geophysical survey at the Creston target has been completed by Abitibi Geophysics of Val-d'Or, Quebec.   Results are pending.   The Creston target is defined by a 2-km-diameter copper soil and rock-sample anomaly representing one of the largest copper footprints on the Burin Peninsula.  A diatreme breccia pipe complex measuring approximately 1,600 × 800 metres occupies the centre of the target.  Three phases of copper mineralization are noted in the diatreme breccia, along with lead and zinc mineralization interpreted to have precipitated from a vapour phase, which the Company considers to be permissive of an underlying magmatic-hydrothermal system.
