SUP - Northern Superior Highlights Impressive Results and Near-Term Milestones for the Philibert Project

Toronto, Ontario--(Newsfile Corp. - June 21, 2023) - Northern Superior Resources Inc. (TSXV: SUP) (OTCQX: NSUPF) ("Northern Superior" or the "Company") is pleased to provide a summary of all historic work completed on the Philibert project, located 60 kilometres southwest of Chibougamau, Québec (the "Philibert Project").

The Philibert Project, which was acquired through the transformative acquisition of Royal Fox Gold Inc. ("Royal Fox") in November 2022, remains arcane as extensive exploration was conducted by SOQUEM (a subsidiary of Investissement Quebec), followed by Royal Fox, and now by Northern Superior, without formalizing an updated mineral resource estimate since 1991.¹ As the Company has reached an advanced stage of such an independent resource calculation with Goldminds Geoservices, it is worth reviewing the overall exploration results to date. The Company owns 75% of the Philibert Project and has an option to acquire the remaining 25% from SOQUEM, leading to 100% ownership of the project.

Moreover, it is important to note that the Philibert Project comprises five main zones, with the northwest and southeast domains being the primary components. Historically, a 300-meter gap has always existed between those two domains due to a simple lack of exploration. Building on the remarkable success of the recent drilling programs across all five main zones, as outlined below, Northern Superior has undertaken a 3,000-metre drilling program earlier this year, in order to investigate this gap area. While some peripherical results have proven encouraging, should the gap demonstrate contiguous mineralization, it would open the door to link the mineralization of the two domains and envision a potential larger, more continuous open pit operation for all zones, which could eventually also facilitate operational access to the higher-grade mineralization at depth. The results from this strategic program are anticipated shortly.

Simon Marcotte, President and Chief Executive Officer of Northern Superior, commented: "Having invested substantial effort and resources into advancing the Philibert Project, we are eagerly anticipating the final results and the impending completion of the mineral resource estimate. We firmly believe that these outcomes will not only establish Philibert as a pillar within the camp but also propel the Chibougamau Gold Camp to become a globally recognized tier-1 asset."

The Philibert Project is located only 9 kilometres from IAMGOLD's Nelligan Project, which was awarded the "Discovery of the Year" by the Québec Mineral Exploration Association (AEMQ) in 2019. Nelligan recently witnessed a 72% increase in its NI-43 101 resource estimate following an additional 22,000 metres of drilling, and now encompasses a total of 1.9 million ounces in the indicated category and 3.6 million ounces in the inferred category, using a 0.35 g/t cut off.²

Geological Context

The 3-kilometre Philibert trend has five main zones that define the mineralization starting in the northwest with Red Fox, Corsac Fox, Arctic Fox, Fennec Fox and Grey Fox. Mineralization is open along strike, down dip and plunge as well as the potential to find new NW-SE shear zones north and south of the current trend. (See Table 1 and Figures 1 to 4). The Company also believes areas like the 300-metre gap between Arctic Fox and Fennec Fox, could be mineralized allowing for one resource model for the entire trend.

Starting in the northwest, the Red Fox Zone has been defined over 650 metres along strike and up to 525 metres vertical depth. In 2022 drilling intersected high-grade mineralization at surface near the eastern limit of the defined domain. Results from this drilling included hole PB-22-417 returning 2.13 g/t Au over 31.4 metres starting at 25 metres, PB-22-336 returning 1.69 g/t Au over 35.6 metres starting at 26.5 metres, and PB-22-335 returning 0.85 g/t Au over 39.3 metres starting at 15.7 metres. Most of the 2022 program was designed to define the surface extent of the Red Fox Zone. One hole tested the western extension of the Red Fox Zone with hole PB-22-375 returning 4.48 g/t over 3.9 metres starting at 90.6 metres. Most of the deeper drilling testing mineralization down dip and at depth was completed historically with highlights including hole 981-14-283 returning 8.05 g/t Au over 17.9 metres starting at 282.0 metres, 981-90-155 returning 3.99 g/t Au over 26.6 metres starting at 321.4, and 981-90-156 returning 3.06 g/t Au over 21.8 metres starting at 412.1 metres. The interpreted plunge of mineralization is steep east to southeast and the Company is investigating the potential of a shallow plunging system.

Moving north drilling tested the western extension of what is interpreted as the Arctic Fox Zone with drill hole PB-22-327A returning 1.48 g/t Au over 16.0 metres starting at 299.0 metres, and 1.28 g/t Au over 22.4 metres starting at 335 metres. Most of the other holes drilled in this area successfully tested mineralization near surface expanding the mineralized corridor. Future work is planned to sample historic drill holes in this area as they were selectively sampled.

Moving north drilling tested the interpreted hanging wall of the Philibert trend and the Corsac Fox Zone which has been weakly defined over 800 metres along strike and up to 250 metres vertical depth. Most of the 2022 drilling tested the domain along strike and near surface. Results included hole PB-22-331 returning 2.11 g/t Au over 27.0 metres starting at 127.0 metres, PB-22-327A returning 0.89 g/t Au over 22.9 metres starting at 130.1 metres, and PB-22-322B returning 2.81 g/t Au over 6.1 metres starting at 120.5 metres. Within the 800-metre-long trend a 120-metre gap in mineralization occurs due to a lack of drilling. Down dip of this area one historical hole PH-93-214 tested the zone at depth and returned 1.32 g/t Au over 41.0 metres starting at 209.0 metres. Geology in the area shows continuity along strike for over a kilometre marked by a fault in a graphitic argillite at the footwall contact of the domain.

Moving east is the Arctic Fox Zone, part of the footwall mineralization, which is defined over 600 metres along strike and up to 275 metres vertical depth. To the east the Arctic Fox Zone extends into the 300-metre gap with limited drilling. The 2022 program mostly focused on infill drilling at surface and at depth along the strike of the zone including the southern and northern domains. Results included some of the best intersections to date with hole PB-22-360 returning 5.96 g/t Au over 10.0 metres starting at 180.0 metres, PB-22-339 one of the deepest holes to test the southern part of the Arctic Fox Zone at a vertical depth of 270 metres, returning 2.94 g/t Au over 14.0 metres starting at 340.0 metres, PB-22-385 returning 2.22 g/t Au over 25.7 metres starting at 92.3 metres, and PB-22-351 returning 4.57 g/t Au over 11.0 metres starting at 68.0 metres. Historical intersections include hole 981-12-267 returning 4.47 g/t Au over 13.2 metres starting at 124.8 metres, 91-88-096 returning 3.11 g/t Au over 18.9 metres starting at 79.1 metres, and 981-88-102 returning 3.44 g/t Au over 16.5 metres starting at 249.2 metres. The Company is pleased with the continuity and exceptional gold values returned from the 2022 drilling program. Future expansion is planned to the east along strike towards the gap and down plunge interpreted to be steep east to southeast with the possibility of an additional shallow plunging ore shoot.

Fennec Fox is located to the west of the 300-metre gap and has been defined over 480-metre along strike and up to 250 metres vertical depth. Drilling focused on infill and some expansion to the east and west along strike. The best hole reported for the 2022 drilling was located at the western limit of the defined Fennec Fox Zone, where the late aged NE-SW oriented Obatogamau Fault transects the NW-SE oriented mineralized Philibert trend. Drill hole PB-22-377 returned 4.29 g/t Au over 21.5 metres starting at 78.5 metres. Drilling also tested the near surface extent with results including hole PB-22-355 returning 1.17 g/t Au over 15.8 metres starting at 34 metres, PB-22-362 returning 0.72 g/t over 28.3 metres starting at 33.5 metres, and PB-22-365 returning 1.33 g/t Au over 10.5 metres starting at 27.0 metres. Historical intersections include hole 981-12-248 returning 6.40 g/t Au over 15.0 metres starting at 39.5 metres, 981-88-079 returning 5.89 g/t Au over 12.2 metres starting at 113.0 metres, 981-12-248 returning 3.63 g/t Au over 13.5 metres starting at 67.5 metres and 981-88-110 returning 1.02 g/t Au over 32.6 metres starting at 188.9 metres. Work to the west in the fault-gap zone returned very interesting results with hole PB-22-382 returning 3.86 g/t Au over 15.0 metres and PB-21-321 returning 2.76 g/t Au over 9.4 metres. The Company has recently completed infill drilling in this area to possibly connect the southeast and northwest domains as one model.

Moving southeast, the Grey Fox Zone has been defined over 500 metres along strike and up to 250 metres vertical depth at the eastern limit of the Philibert trend. The 2022 drill program focused on definition and extension of the mineralized zone along strike. Results included hole PB-22-383 returning 2.44 g/t Au over 21.0 metres starting at 57.1 metres and PB-22-381 drilled down dip returned 1.78 g/t Au over 17.5 metres starting at 140.0 metres highlighting the exceptional consistency of the mineralization. From the southeastern limit of the Grey Fox zone, hole PB-22-420 returned 2.07 g/t Au over 11.4 metres starting at 9.6 metres which is one of the most southeastern drill holes testing the mineralized corridor and represents an important target for the Company in the future to expand along strike and down-plunge. At the western limit of the Grey Fox Zone hole PB-22-399 intersected 1.37 g/t Au over 6.0 metres starting at 9.0 metres and hole PB-22-368 drilled down dip returned 1.42 g/t Au over 10.1 metres starting at 108.4 metres successfully expanding the strike of the zone by 80 metres. Historical drilling and due diligence drilling from 2021 returned some the widest intersections to date with hole 981-12-244 returning 2.23 g/t Au over 54.5 metres starting at 32.0 metres, and hole PB-21-316 returning 1.23 g/t Au over 55.5 metres starting at 30.0 metres. Hole PB-22-426 drilled as an infill hole 40 metres west of the PB-21-316 returned 0.92 g/t Au over 59.5 metres starting at 53 metres again highlighting the exceptional consistency of the mineralization.

Mineralization is hosted in a quartz rich gabbro named the Philibert Horizon, part of the Obatogamau Formation, and focused within west-northwest to northwest trending silicified shear zones with moderate dips to the northeast. Mineralization is characterized by strong silicification, ankerite, sericite and locally fuchsite alteration, quartz-carbonate-tourmaline, and dark grey quartz only veining with rare Visible Gold and up to 2-5% disseminated pyrite and pyrrhotite mineralization. At the Corsac Fox Zone the lower contact is marked by a fault within a graphitic argillite horizon. Extension to the northwest of the Arctic Fox zone is hosted in mineralized basalt units with similar alteration style but less disseminated sulphide and more abundant quartz veining.

Exploration beyond the defined mineralized trend has some exciting targets to test in the future including hole 981-90-182 returning 1.66 g/t Au over 26.0 metres starting at 72.5 metres approximately 1.7 km along strike of the Grey Fox Zone and PH-93-196 returning 2.81 g/t over 13.3 metres starting at 306.4 metres approximately 500 metres northeast of the Grey Fox Zone. The Company is planning future work to expand and connect mineralization to the main Philibert trend.
