Northern Superior begins exploration at Hazeur

Mr. Simon Marcotte reports NORTHERN SUPERIOR EXPANDS PHILIBERT MINERALIZATION POTENTIAL WITH 1.10 G/T AU OVER 25.5 METRES, 350 METRES WEST OF CURRENT PIT, FROM HISTORICAL DRILLING AT HAZEUR AND ANNOUNCES FURTHER LAND ACQUISITIONS Northern Superior Resources Inc. has commenced exploration activities on its newly acquired Hazeur property, strategically located adjacent to its flagship Philibert project in Quebec's Chibougamau gold camp. Additionally, Northern Superior has expanded its Chevrier project through the acquisition of claims totalling 2,100 hectares contiguous with the project's northern boundary, bringing the company's total landholdings in the Chibougamau gold camp to more than 70,000 hectares. Lastly, approximately 90 per cent of the Philibert expansion drilling program has been completed and reported. A final tranche of approximately 2,000 metres remains in progress, with results to be disclosed as assays are received and quality assurance/quality control is finalized. Regarding Hazeur and other newly acquired ground, the company is systematically compiling historical assessment data, relogging and resampling available core to address gaps in prior work and initiating reconnaissance programs across the new land position. (See details of the acquisition of Hazeur, Monster Lake West and Monster Lake East in the press releases dated June 16 and July 17, 2025.) Highlights include (grades uncut, lengths are measured along the drill hole and true widths are unknown at this time): Hazeur: HA-16-004: 1.10 grams per tonne gold over 25.5 metres, including 7.28 g/t Au over 1.7 metres starting at 82.5 metres -- located approximately 350 metres west of the Philibert conceptual pit and believed to represent the western extension of the Red Fox zone; and Hazeur HA-16-003: 0.94 g/t Au over 8.9 metres starting at 99.9 metres, and 1.49 g/t Au over 1.1 metres starting at 118.2 metres -- located over 400 metres west of the conceptual pit and 70 metres west of HA-16-004. "These early Hazeur results demonstrate meaningful gold mineralization immediately west of Philibert, highlighting the potential for resource growth across our expanding land package. The addition of the new claims north of Chevrier adds to the recent acquisition of the Hazeur, Monster Lake West and Monster Lake East properties as we continue to consolidate our position in a camp rapidly gaining global recognition. We are executing a disciplined and cost-effective strategy to acquire high-quality ground and advance our portfolio," said Simon Marcotte, president and chief executive officer. "Our technical team has already identified the western extension of the Red Fox zone over a 600-metre strike length west of the Philibert pit. Relogging and resampling are filling gaps in the historic record, and reconnaissance work has collected 80 outcrop samples in the Kapunapotagen fault zone. We are confident this work will generate strong drill targets to expand Philibert and test new ground within the Hazeur and Chevrier projects," said Adree DeLazzer, vice-president of exploration. Compilation of results The company's geological team is actively compiling historic data from the eastern half of the Hazeur property and has undertaken a program of relogging and resampling to close gaps in earlier work. This review has confirmed what the team interprets as the western extension of the Philibert Red Fox mineralized zone, traced for approximately 600 metres west of the current conceptual pit. Drill hole HA-16-004 intersected 25.5 metres at 1.10 grams per tonne gold, including 7.28 g/t Au over 1.7 metres, within a strongly silicified and albitized gabbro hosting disseminated pyrite and pyrrhotite. A second hole, HA-16-003, collared 60 metres farther west and more than 400 metres from the nearest Philibert resource drill holes, cut the same mineralization style typical of the Philibert footwall zones. Results included 0.94 g/t Au over 8.9 metres and 1.49 g/t Au over 1.1 metres, although unsampled intervals remain in mineralized sections and will be addressed in follow-up work. Beyond the Red Fox extension, compilation work has highlighted other zones of interest across Hazeur, including the 7597 series of shallow historical holes, which encountered near-surface but lower-grade mineralization. These results suggest multiple mineralized horizons across the property, warranting systematic evaluation. To advance this potential, Northern Superior is finalizing an exploration drilling program designed to test the western continuation of the Red Fox footwall zones, with drilling scheduled to begin later this month. In parallel, the company is planning fieldwork focused on mapping, prospecting and targeted sampling in areas of abundant bedrock exposure. This program will also establish a surface geochemical grid along the Guercheville deformation zone, a key regional structure, to further refine drill targeting. New land acquisitions The company has also expanded its land position through the acquisition of 38 new map-designated claims (CDC) covering more than 2,100 hectares contiguous to the north of the Chevrier property. These claims straddle the Chapais syncline, a large and underexplored sedimentary-volcanic basin unconformably overlying the Roy group. The syncline is cut by the Kapunapotagen fault zone, a major reverse shear corridor known to act as a conduit for mineralizing fluids. Despite its favourable geological setting, the area has seen very limited systematic exploration to date, as evidenced by the sparse detail on the geological map and very limited drilling. Northern Superior's geological team has already initiated reconnaissance work, including mapping and the collection of 80 surface samples, with results pending. The potential of this new land package lies in its geological diversity. The Hauy and Stella formations, which form part of the Chapais syncline, could host a variety of mineral systems. Felsic volcanic centres within these sequences may prove prospective for volcanogenic massive sulphide deposits, much like those of the Noranda camp. Faults cutting Opemisca sediments and volcanics provide structural traps for magmatic-hydrothermal copper-gold veins, analogous to the historic Springer and Perry mines at Opemiska. Meanwhile, carbonaceous sedimentary members intersected by shear zones are prospective for orogenic gold systems, drawing comparisons with camps such as Detour Lake and Malartic. The underexplored nature of the ground, combined with these multiple mineralization models, highlights the strategic value of this acquisition. Several showings and mineralization have been identified near the edges of the basin. The Chibougamau gold camp The Chibougamau gold camp is rapidly emerging as one of the world's most sought-after gold destinations with several complementary gold resources reaching viable scale. In recent years, these critical assets were divided amongst five different companies. Today, largely due to Northern Superior's acquisitions and corporate transactions, ownership has been streamlined, with only Iamgold and Northern Superior holding these assets. The proximity of these deposits to each other makes them ideally suited to feed a single mill, and their consolidation enhances their viability, thereby increasing their value.
