NORTHERN SUPERIOR REPORTS POSITIVE METALLURGICAL TESTING WITH FLOTATION CONCENTRATE RECOVERIES UP TO 95.6%

Northern Superior Resources Inc. has released results from metallurgical testing conducted at SGS Laboratory from its Philibert gold deposit, located 60 kilometres southwest of Chibougamau, Que., Canada (Northern Superior: 75 per cent; Soquem: 25 per cent).

Highlights include:

• Arctic Fox South zone with 95.6 per cent of the gold in 9.5 per cent of mass;
• Arctic Fox North zone with 93.3 per cent of the gold in 13.2 per cent of mass;
• Red Fox zone with 95.5 per cent of the gold in 15 per cent of mass.

Simon Marcotte, president and chief executive officer of Northern Superior, commented: "With such high recovery of the gold content in a flotation concentrate, recovering the gold in an efficient manner is not expected to be an issue. The gold recovery by flotation from all areas tested to date is favourable and increases our confidence that the Philibert project demonstrates the right attributes to achieve strong potential economics in the future."

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 hangingwall zone of the Philibert project, including the Arctic Fox South, Arctic Fox North and Red Fox zones. The flotation metallurgical tests were done on two-kilogram test charges ground to 75 micrometres and subjected to flotation under typical conditions for sulphide flotation. The two flotation products were analyzed for gold, silver and sulphur.

The evaluated samples ranged in head grade from 1.85 grams per tonne Au (composite 3) to 5.10 g/t Au (composite 1). The silver content was less than two g/t in all three samples. The three composites responded well to sulphide flotation, with sulphide recoveries from 95 per cent to 97 per cent, gold recoveries from 93 per cent to 96 per cent and silver recoveries from 38 per cent to 68 per cent, at between 10-per-cent and 15-per-cent mass recovery. Gold and silver contents in the flotation tails were very low at less than 0.2 g/t and less than 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 per cent (composite 3) to 96 per cent (composite 1).

The attached table shows results for screened metallic analysis for Au and Ag by fire assay, sulphur by Leco, whole rock analysis by inductively coupled plasma 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 metallic 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 metallic analysis.

The detailed mass balance of the three composite tests are as noted herein.

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 to 90 micrometres, yielding greater than 93-per-cent gold and sulphide recoveries in mass recoveries of 10 to 15 per cent.
• The three flotation concentrates responded well to cyanidation at a regrind of 50 to 60 micrometres, yielding gold recoveries of 91 to 96 per cent. Cyanide consumptions of 1.5 to 2.3 kg/t NaCN (sodium cyanide) 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 by cyanidation of flotation concentrates were in the 86-to-92-per-cent range.
• 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.

Sampling and laboratory

True widths of the intercepts reported in this press release have yet to be determined but are estimated to be 60 per cent to 90 per cent 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 parts per million Au are reanalyzed, utilizing standard fire assay-gravimetric methods. Samples were shipped to Agat Laboratories with sample preparation done in Val d'Or, Que., and sample analysis done in Mississauga, Ont. The quality assurance and quality control protocol includes 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 National Instrument 43-101 mineral resource estimate on the Philibert project.

About Northern Superior Resources Inc.

Northern Superior is a gold exploration company focused on the Chibougamau camp in Quebec. The company has consolidated the largest land package in the region, with total landholdings currently exceeding 62,000 hectares. The main properties include Philibert, Lac Surprise, Chevrier and Croteau Est. Northern Superior also owns significant exploration assets in Northern Ontario highlighted by the district-scale TPK project.

The Philibert project is located nine kilometres from Iamgold Corp.'s Nelligan gold project which was awarded the Discovery of the Year by the Quebec Mineral Exploration Association (AEMQ) in 2019. To date, more than $15-million (historical value) has been spent on the Philibert project, with more than 77,000 metres of drilling completed. Northern Superior holds a majority stake of 75 per cent in the Philibert project, with the remaining 25 per cent owned by Soquem. The company retains the option to acquire the full 100-per-cent ownership of the project. Chevrier hosts an inferred mineral resource of 652,000 ounces Au (underground and open pit) and an indicated mineral resource of 260,000 ounces Au. Croteau Est hosts an inferred mineral resource of 640,000 ounces Au. Lac Surprise hosts the Falcon zone discovery, interpreted to be the western strike extension of Iamgold's Nelligan deposit.
