TORONTO, ON / ACCESS Newswire / May 13, 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 measured along hole; see Table 1):
New Zone Discovered Beneath and South of Current Resource: PB-25-484: 2.48 g/t Au over 18.0 metres (620.0 m to 638.0 m), including 7.02 g/t Au over 4.9 metres (621.1 m to 626.0 m);PB-25-480: 0.70 g/t Au over 50.3 metres (148.7 to 199.0 m), including 1.47 g/t Au over 13.3 metres (185.7 to 199.0 m), located beneath the current resource pit at the Fennec Fox footwall ("FW") zone;PB-25-478: 0.48 g/t Au over 32.6 metres (147.0 m to 179.6 m), including 1.42 g/t Au over 7.5 metres (167 m to 179.5 m), located below the current resource pit at the Grey Fox FW zone; andNew Core Area Outside Current Resource Pit: These holes, along with previously reported PB-25-475, PB-25-476, and PB-25-477 (see press releases dated March 3 and March 25, 2025), define a new core area intersecting the Grey Fox and Fennec Fox FW zones along a 400-metre strike and between 150-200 metres vertically. All six (6) holes are outside the current resource pit, and the target remains open along strike and at depth.
"Today's results underscore the significant expansion potential at Philibert, with hole PB-25-484 marking a new high-grade discovery that opens the door for underground resource development. The additional drill holes reported further build on our ongoing success at the southeastern extent of the pit and reinforce the strong potential to grow the resource well beyond the current 1.71 million ounces at 1.1 g/t gold in the inferred category and 279,000 ounces at 1.1 g/t gold in the indicated category. Philibert is rapidly emerging as a cornerstone asset within the evolving Chibougamau Gold Camp," said Simon Marcotte, President and Chief Executive Officer.
"We're particularly excited by hole PB-25-484, which delivered both significant grade and width, demonstrating the strong potential to add high-quality ounces to our overall resource base. This intercept confirms that mineralization continues down-dip and becomes enriched at vertical depths exceeding 500 metres, providing compelling targets for continued expansion. In addition, we intersected significant mineralization across a 150-metre strike length in an area that had seen limited historical drilling. Situated between the Fennec Fox and Grey Fox zones, these new intercepts-together with previously reported results-highlight the potential to define a continuous, 400-metre mineralized corridor underneath the current pit shell, where its geometry remains shallow compared to the depth of the Red Fox Zone (See Figure 1)," added Adree DeLazzer, Vice President of Exploration.
1PB-25-484: 18.0 metres from 620.0 m to 638.0 m at 2.48 g/t Au including 4.9 metres from 621.1 m to 626.0 m at 7.02 g/t Au; PB-25-480: 50.3 metres from 148.7 m to 199.0 m at 0.70 g/t Au including 13.3 metres from 185.7 m to 199.0 m at 1.47 g/t Au.

Drilling Results
Drillhole PB-25-484 targeted a section of the resource with limited drilling density, where the pit shallows. It intersected 2.48 g/t Au over 18.0 metres, including 7.02 g/t Au over 4.9 metres, from a downhole depth of 620 metres (~520 metres vertical). The mineralization may represent a new zone or a down-plunge extension of the Arctic Fox FW zone. Historical drilling suggested deeper potential, with nearby intercepts located 190 metres up-dip and 150 metres along strike (see Table 1 and Figures 1, 2, and 3).
Drillhole PB-25-478 intersected 0.48 g/t Au over 32.6 metres, including a higher-grade interval of 1.42 g/t Au over 7.5 metres, down-dip of the Grey Fox FW zone. The mineralized zone occurs at 140 metres vertical depth, or approximately50 metres beneath the current resource pit shell (see Table 1 and Figures 1, 2, 4 and 6).
PB-25-479, collared 60 metres west and down-dip of PB-25-478, returned a discrete high-grade intercept of 8.35 g/t Au over 0.5 metres and a lower grade intersection of 0.45 g/t Au over 6.0 metres within a wider weakly anomalous interval of 0.31 g/t Au over 29.6 metres. This hole tested a sparsely drilled area outside the modeled plunge of mineralization between the Fennec Fox and Grey Fox FW zones. Mineralization was encountered at a vertical depth of 150 metres, approximately 120 metres below the pit shell, in a section where the pit geometry flattens toward surface (see Table 1 and Figures 1, 2, 4 and 6).
PB-25-480, drilled 80 metres west of PB-25-479, intersected 0.70 g/t Au over 50.3 metres, including 1.47 g/t Au over 13.3 metres, at a vertical depth of 160 metres, approximately 100 metres below the resource pit in an area where the pit shallows to surface (see Table 1 and Figures 1, 2, 4 and 5).
Gold mineralization is hosted within the siliceous phase of the Philibert gabbro seam, characterized by pervasive silicification, quartz veining, ankerite and sericite alteration, and 1-15% disseminated pyrite-pyrrhotite.
When combined with previously released intercepts-including PB-25-475: 1.94 g/t Au over 31.0 metres, PB-25-477: 2.03 g/t Au over 19.7 metres (see press release dated March 25, 2025), and PB-25-476: 2.89 g/t Au over 10.6 metres, including 5.15 g/t Au over 5.3 metres (see press release dated March 3, 2025)-the data define a 400-metre mineralized corridor situated outside the current resource pit envelope (refer to Figure 1 - longitudinal section of the Philibert Trend, and Figure 4 - inclined long section).

Grades have not been capped in the averaging and intervals are reported as drill thickness. True widths are estimated at 70 to 90%. 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. * Intersections are determined using 0.1 g/t Au cut-off and no more than 15 metres of consecutive dilution.

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,2 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.
