Northern Superior Reports 11.99 g/t Au Over 9.1 Metres Including 101 g/t Au Over 1.0 Metre, and 1.75 g/t Au Over 65.0 Metres Including 3.92 g/t Au Over 17.4 Metres at Philibert

TORONTO, ON / ACCESS Newswire / July 30, 2025 / Northern Superior Resources Inc. (“Northern Superior” or the “Company“) (TSXV:SUP)(OTCQB:NSUPF)(GR:D9M1) is pleased to announce additional results from its 20,000-metre expansion drilling campaign at the Philibert gold property, located just 9 km from IAMGOLD Corporation’s (“IAMGOLD“) Nelligan project and 60 km southwest of Chibougamau, Quebec (the “Philibert Project“: Northern Superior: 75%, SOQUEM: 25%).

Highlights Include: (Grades uncut; lengths are measured along the drill hole. See Table 1 for details.)

• PB-25-490: 11.99 g/t Au over 9.1 metres, including 101.0 g/t Au over 1.0 metre, starting at 104.5 metres – Corsac Fox Hanging Wall Zone;

• PB-25-502: 0.73 g/t Au over 46.8 metres, including 1.86 g/t Au over 9.5 metres, starting at 232.7 metres – Corsac Fox Hanging Wall Zone;

• PB-25-504: 1.83 g/t Au over 18.8 metres, including 3.02 g/t Au over 10.6 metres, starting at 6.7 metres, and 1.75 g/t Au over 65.0 metres, including 3.92 g/t Au over 17.4 metres, starting at 94.5 metres – Arctic Fox Footwall Zone drilled parallel and down dip of mineralization (see Figure 3); and

• PB-25-505: 1.29 g/t Au over 33.0 metres, including 5.71 g/t Au over 1.7 metres, starting at 9.0 metres – Arctic Fox Footwall Zone drilled parallel and down dip of mineralization.

“Today’s results focus on the middle and western extent of the conceptual pit, where we aimed to expand the Corsac Fox Hanging Wall zones. Hole PB-25-490 intersected very high grades near surface, outside of the current conceptual pit, and confirms the opportunity for significant resource expansion in this area. Moreover, drilling has filled in areas previously interpreted as non-mineralized due to sparse historical drilling,” said Simon Marcotte, President and Chief Executive Officer of Northern Superior.

“We are particularly encouraged by PB-25-504 (see Figure 3), which intersected mineralization right at the contact between the bedrock and overburden, just 4.7 metres vertically from surface-demonstrating the near-surface potential of this system. The continued success at the southeast pit, the recent deep high-grade hits, and now this new hanging wall mineralization, all underscore the potential to grow Philibert well beyond the current resource,” he added.

“PB-25-490 stands out with exceptional grade and width in an area where the pit shallows due to sparse historical drilling,” said Adree DeLazzer, Vice President of Exploration for Northern Superior. “Drillholes such as PB-25-502, which intersected 0.73 g/t over 46.5 metres, confirm strong mineralization continuity with meaningful width. These new intersections, located north of the Red Fox and Arctic Fox Footwall zones along the northern wall of the conceptual pit, continue to support our strategy of growing near-surface ounces along the 4-5 km Philibert trend. New structural and geochemical data are significantly enhancing our understanding of this large and evolving gold system,” she added.

Grades have not been capped in the averaging and intervals are reported as drill thickness. True widths are estimated at 70% to 90%, except for drill holes marked with “*” which were drilled down dip and parallel to mineralization, with true widths estimated at 40% to 60%. Intersections are determined using 0.3 g/t Au cut-off and no more than 15 metres of consecutive dilution. If an intersection is 1 metre or less, dilution under 0.1 g/t Au may be used to determine a 2-metre intersection.

Drilling Results
The current drill program tested the Corsac Fox Hanging Wall over a 750-metre strike length where historical drill density was low (see figures 1 and 2). Results from ten drill holes show that the Hanging Wall domains have a different style of mineralization to the well known footwall domain. The Hanging Wall domains are caracterized by a high-grade vein-style gold and broader envelopes near the northern wall of the conceptual pit (see tables 1 and 2). The hanging wall domains show a strong nugget effect compared to the footwall zones, and visible gold is frequently observed.

PB-25-490, located approximately 80 metres vertically from surface and 60 metres below the pit shell, intersected 11.99 g/t Au over 9.1 metres including 101.0 g/t Au over 1.0 metre. Another three drill holes tested the area where the conceptual pit shallows to surface over approximately 200 metres. PB-25-492, located 60 metres west of PB-25-490, returned 1.87 g/t Au over 3.3 metres. PB-25-489, situated 90 metres east of PB-25-490, intersected several narrow, higher-grade intervals, including 4.82 g/t Au over 1.5 metres, 2.17 g/t Au over 2.4 metres, and 4.15 g/t Au over 1.2 metres. PB-25-494, drilled 120 metres west of PB-25-490, returned multiple intervals from the hanging wall zones, including 6.54 g/t Au over 1.5 metres, 1.15 g/t Au over 5.7 metres, and 1.15 g/t Au over 6.0 metres.

Two drill holes were completed from the same setup approximately 600 metres west of PB-25-490, slightly off the main azimuth, to test the continuity of mineralization within the hanging wall zones in the western portion of the pit. PB-25-502 returned a broad intercept of 0.73 g/t Au over 46.8 metres, including a higher-grade interval of 1.86 g/t Au over 9.5 metres, highlighting strong potential for continuous, near-surface mineralization. PB-25-500 intersected 0.94 g/t Au over 15.5 metres, including 7.67 g/t Au over 1.5 metres, as well as additional higher-grade, narrower intervals such as 7.11 g/t Au over 2.2 metres and 10.68 g/t Au over 1.2 metres.

Two drill holes, PB-25-504 and PB-25-505, were completed to test the Arctic Fox Footwall zones down-dip of known mineralization, each drilled at different orientations to collect critical structural data and improve our geological understanding of the system. PB-25-504 intersected multiple broad and high-grade intervals including 18.8 metres grading 1.83 g/t Au from 6.7 metres, with a higher-grade core of 10.6 metres of 3.02 g/t Au. A second major zone returned 65.0 metres of1.75 g/t Au from 94.5 metres depth, including 17.4 metres of 3.92 g/t Au, with sub-intervals such as 4.0 metres of 5.37 g/t Au. PB-25-505 also intersected a broad mineralized zone of 33.0 metres of 1.29 g/t Aufrom9.0 metres, including a higher-grade section of 1.7 metres at 5.71 g/t Au. These holes confirm the presence of continuous and robust mineralization at the bedrock interface in the Arctic Fox Footwall and provide valuable data for refining the deposit’s structural model. Less historic work has been completed on the northern hanging wall domains, and the geological model and mineralization controls are currently being investigated using new structural core orientation and geochemical data to further refine the model.

The team is developing a follow-up drilling program to further investigate the higher grade near-surface mineralization as well as at depth to increase the ounces in the resource pit and potentially add an underground component to the resource.

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,^[1] 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.

Below is a table showing the resources of the camp having been formalized to date.
