Northern Superior Resources Inc. reported results from metallurgical testing conducted at SGS Laboratory from its Philibert gold deposit, located 60 kilometres southwest of Chibougamau, Québec, Canada. A metallurgical test program was completed on three composites from the Philibert deposit, where the main objective was to develop initial metallurgical data to evaluate if the style of mineralization is amenable to flotation followed by cyanidation. Results indicate that cyanidation of the tails may not be required.

The 34 independent samples on halved NQ drill core used in the program were collected by GoldMinds Geoservices Inc. from the 2022 drilling campaign for sample preparation and gold analysis, head and composite analysis, flotation on three composites, cyanidation and flotation of tails. The three composites were selected from the hanging wall zone of the Philibert Project including the Arctic Fox South, Arctic Fox North, and Red Fox zones. The flotation metallurgical tests done on 2 kg test charges ground to P80 = 75 µm and subjected to flotation under typical conditions for sulphide flotation.

The two flotation products were analyzed for gold ("Au"), silver ("Ag"), and sulphur ("S"). The evaluated samples ranged in head grade from 1.85 g/t Au (Composite 3) to 5.10 g/t Au (Composite 1). The silver content was <2 g/t in all three samples.

The three composites responded well to sulphide flotation, with sulphide recoveries from 95% to 97%, gold recoveries from 93% to 96%, and silver recoveries from 38% to 68%, at between 10% and 15% mass recovery. Gold and silver contents in the flotation tails were very low at <0.2 g/t and <0.5 g/t, respectively. Because of the low gold and silver contents in the tails, it was decided to only carry out the cyanidation tests on the flotation concentrates.

Cyanidation of the flotation concentrates yielded final gold extractions ranging from 91% (Composite 3) to 96% (Composite 1). results for screened metallic analysis for Au and Ag by Fire Assay, Sulphur by Leco, whole rock analysis by ICP method, and Graphitic carbon. The head grade was calculated using a 500- gram spilt of the screen metallic analysis.

The gold ore grades obtained corresponded well with the results of the calculated average gold grade for Composite 2 and Composite 3 (2.90 g/t versus 2.56 g/t for Composite 2 and 1.89 g/t versus 1.85 g/t for Composite 3). However, the calculated gold grade for Composite 1 was 2.77 g/t versus a grade of 5.10 g/t obtained by screened metallics analysis. The difference is likely due to sampling challenges and the presence of coarse particles of gold in the 500- gram charge used for the screened metallics analysis.

The following conclusions can be drawn from the scoping test work on composite samples from the Philibert Project: The three composites tested responded well to conventional sulphide flotation at primary grinds of 80-90 m (P80), yielding >93% gold and sulphide recoveries in mass recoveries of 10-15%; The three flotation concentrates responded well to cyanidation at a regrind P80 of 50 to 60 m, yielding gold recoveries of 91 to 96%. Cyanide consumptions of 1.5 to 2.3 kg/t NaCN were reasonable for concentrate leaching. These consumptions are equivalent to 0.18 to 0.23 kg/t NaCN on a whole mineralized zone basis; Overall gold recoveries via cyanidation of flotation concentrates were in the 86% to 92% range; and Despite the close association between gold and the sulphide minerals in the flotation process, the test work shows the gold in this deposit is not locked in the sulphides and is amenable to cyanidation.

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 for 2022 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. Additional tests may be carried out later in the year, but the results are sufficient to enable the preparation of the first maiden NI 43-101 mineral resource estimate on the Philibert Project.
