Northern Superior Reports 2.13 G/T Gold Over 31.4 Metres and 4.84 G/T Gold Over 3.9 Metres From the Red Fox Zone of the Philibert Project

TORONTO, May 11, 2023 - Northern Superior Resources Inc. ("Northern Superior" or the "Company") (TSXV:SUP)(OTCQX:NSUPF) is pleased to report the remaining assay results from the Red Fox Zone (see Figures 1 and 2) of the Philibert gold property (see press release dated January 11, 2023), located 60 kilometres southwest of Chibougamau, Quebec.

Highlights Include (Grades uncut; lengths measured along hole, Table 1):

• 12 Holes Remain Pending from other zones;
• DDH PB-22-417 returned 2.13 g/t Au over 31.4 metres from 25.0 to 56.4 metres from the southeastern extent of the Red Fox zone;
• DDH PB-22-375 returned 4.84 g/t Au over 3.9 metres from 90.6 to 94.5 metres from the western limit of the Red Fox Zone; and
• DDH PB-22-372A returned 4.44 g/t Au over 2.5 metres from 79.2 to 81.7 metres extension of the Red Fox Zone to the northwest.

Simon Marcotte, President & Chief Executive Officer of Northern Superior, commented: "The results communicated today continue to demonstrate the exceptional grade and width of the Red Fox Zone. With the campaign uncovering this new high-grade area, we see a clear opportunity to extend near surface mineralization along strike and down plunge towards the east-southeast. Moreover, the drill holes investigating the western extent of the Red Fox Zone have revealed that it remains open in that direction, providing a significant opportunity for the Company to expand the mineralized corridor in the future. Overall, these results continue to demonstrate the significant potential of Philibert as we continue to progress towards a maiden NI-43-101 resource calculation, which we believe will establish Philibert as a pilar in the rapidly emerging Chibougamau gold camp."

Philibert Drill Program

Northern Superior is reporting results today for eleven drill holes which include the last remaining drill holes that tested the Red Fox Zone. (Please refer to Appendix 1 below for the complete results of the drill program on the Red Fox Zone.) This zone is part of the northwestern footwall located within the 3-kilometre long Philibert mineralized corridor. To date, the Red Fox Zone has been defined over 650 metres along strike and up to 525 metres vertical depth (see Figure 1 and 2 and Table 1).

Today's results include drill hole PB-22-417, returning 2.13 g/t Au over 31.4 metres from 25.0 to 56.4 metres from the southern extent of the Red Fox Zone (see Figure 3 and 4). In this area the Company already reported some impressive results, including drill hole PB-22-336 (see Royal Fox Gold Inc. press release dated May 18, 2022) with 1.69 g/t Au over 35.6 metres from 26.5 to 62.1 metres.

Another five drill holes tested the western extension of the Red Fox Zone, with drill hole PB-22-375 returning 4.84 g/t Au over 3.9 metres from 90.6 to 94.5 metres. The Company is keen to expand the strike of the Red Fox Zone to the west and down dip in the next drill program. Drill holes PB-22-370, PB-22-378 and PB-22-354 were designed to test the southern surface extent of mineralization in the west and appear to have been drilled south of the surface extent of the mineralized zone. Drill hole PB-22-361A was the most eastern drill hole to test the Red Fox Zone, which intersected 1.78 g/t Au over 6.5 metres, connecting the mineralized zone to the Arctic Fox Zone.

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 ankerite and silica alteration, cut by dark grey quartz veining and up to 20% disseminated pyrite and pyrrhotite mineralization.

Sampling and Laboratory

True widths of the intercepts reported in this press release have yet to be determined but are estimated to be 60% to 90% of reported core lengths. All NQ-size split core assays reported were obtained by fire assay with atomic absorption finish and samples returning values over 10 ppm Au are re-analyzed, utilizing standard Fire Assay-Gravimetric methods. Samples were shipped to AGAT Laboratories with sample preparation done in Val-d'Or, Québec and sample analysis done in Mississauga, Ontario. The quality assurance and quality control protocol include insertion of blank and standard every 25 samples on average, in addition to the regular insertion of blank, duplicate, and standard samples inserted by AGAT Laboratories during the analytical process.

The technical content and scientific aspects of this press release have been reviewed and approved by Mrs. Adree DeLazzer, P. Geo., a Qualified Person as defined by the National Instrument 43-101. Mrs. DeLazzer is Vice-President Exploration of Northern Superior and is not considered independent.
