Northern Superior Resources Makes New Discovery with 10.94 g/t Gold Over 7.0 Metres and 1.66 g/t Gold Over 21.55 Metres at Croteau Property

Press Release

Toronto, Ontario, Canada, October 16, 2023 – NorthernSuperior Resources (“Northern Superior” or the “Company”) (TSXV: SUP; OCTQB: NSUPF) is pleased to announce results from the diamond drill program on its 100% owned and extensive (30 km x 15 km) Croteau Property.

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

  • DDH CRO-22-150 intersected multiple mineralized zones, including 10.94 g/t Au over 7.00 metres starting at 272.10 metres including 16.15 g/t Au over 4.6 metres and 1.66 g/t Au over 21.55 metres starting at 224.0 metres, including 3.20 g/t Au over 2.0 metres and 4.87 g/t Au over 4.65 metres, 1.26 g/t Au over 7.15 metres, starting at 315.85 metres (including 2.70 g/t Au over 2.0 metres and 0.53 g/t Au over 11.5 metres, starting at 330.0 metres;
  • DDH CRO-22-127ext, intersected multiple mineralized zones, including 1.33 g/t Au over 16.80 metres starting at 375.20 metres including 3.25 g/t Au over 3.5 metres, and 1.29 g/t Au over 9.40 m, starting at 285.00 metres, including 5.16 g/t Au over 2.00 m (approximately 250m east of CRO-22-150 and 128);
  • DDH CRO-22-128 returned 1.32 g/t Au over 12.50 metres starting at 237.25 metres including 6.58 g/t Au over 1.00 metre (on strike of CRO-22-150 and 127Ext);
  • DDH CRO-22-147 returned 1.31 g/t Au over 13.30 metres starting at 220.00 metres, including 3.56 g/t Au over 2.90 metres;
  • Numerous gold values in step-out drilling of the mineralization discovered in 2022 in CRO-22-120 (1.06 g/t Au over 26.30 metres; see press release dated July 19, 2022), highlighted by hole CRO-22-137, which intersected 12.82 g/t Au over 1.9 metres starting at 63.10 metres, including 40.30 g/t Au over 0.60 metres;
  • DDH CRO-22-135, drilled between the Z120 Zone and the historic Croteau-Est Showing, intersected 5.13 g/t Au over 3.05 metres starting at 254.30 metres;
  • DDH CRO-22-151 returned 1.65 g/t Au over 5.00 m, starting at 285.00 metres; and
  • DDH CRO-22-152 returned 2.03 g/t Au over 6.50 m starting at 244.80 metres.

This program was designed to test:

  • The discovery area associated with the Croteau North Shear Zone: hole CRO22-120, intersecting 1.06 g/t Au over 26 metres, including 4.98 g/t Au over 3.0 metres, known as Z120, located north and parallel to the Croteau-Bouchard Shear Zone (“CBSZ”). The CBSZ hosts an inferred gold resource of 640,000 ounces[1] (see press release dated July 19, 2022).
  • Targets within the North Basalt Domain (“NBD”) consisting of extensive carbonate-sericite alteration in surface trench exposures and RC bedrock chips supplemented by gold grains in till anomalies from a rigorous Reverse circulation (RC) drill program completed in late 2021 and early in 2022 (see Northern Superior press release January 11, 2022).

Simon Marcotte, President & Chief Executive Officer of Northern Superior, commented: “The results presented today on our Croteau Property underscore the exceptional exploration opportunities inherent in this strategic land package. Not only this newly discovered near surface mineralization in two new areas is within one kilometer of the main zone, already hosting an inferred resource of 640,000 ounces of gold at 1.79 g/t Au, but the high-grade nature of the discovery has the potential to transform the project into a resource even more amenable to a combined single mining operation alongside the Company’s Philibert project and other neighboring projects of the area. We eagerly anticipate building upon this success and expand on the potential of this property’s gold resources.”

Geology in the NBD consists of a sequence of mafic flows intruded by subvolcanic gabbro sills, belonging to the Neoarchean aged Bruneau Formation. Aeromagnetic data suggest this sequence is complexly folded in the target area.

Mineralization consists of disseminated and fracture filling pyrite and quartz-pyrite veins surrounded by siliceous alteration, within wide (>100 metres) zones of strong carbonate-sericite+/-fuchsite alteration.  Higher grades are often associated with higher pyrite concentrations (up to 20%) within hyaloclastite zones in contact with gabbro units. The gabbro units in these altered areas are commonly strongly altered by fuchsite. Significant gold intersections have now been found along a total strike length of 1.5 km, within the North Basalt Domain and the Croteau North Shear Zone (see Figures 1 and 2 below).

DDH CRO-22-128 returned 1.32 g/t Au over 12.50 metres and hole CRO-22-127 was extended to test for the possible strike extension of this mineralization and intersected wide zones of carbonate-sericite-fuchsite-pyrite +/- silica-albite alteration, returning 1.29 g/t Au over 9.40 metres, 0.73g/t Au over 6.15 metres and 1.33 g/t Au over 16.80 metres. This mineralization remains open at depth to the east for at least 400 m.

Hole CRO-22-150 was drilled approximately 100 metres down dip of hole CRO-22-128. The hole encountered the same sequence of pillowed mafic volcanics and massive gabbros, affected by wide zones of strong sericite-carbonate-pyrite alteration, with local fuchsite and sections of strong albite-silica alteration, accompanied by quartz-pyrite veins interpreted to be hosted in hyaloclastite zones, in contact with gabbro (see Figure 3 and 4 below). Results include 1.66 g/t Au over 21.55 metres (including 3.20 g/t over 2.00 metres and 4.87 g/t Au over 4.65 metres) and 10.94 g/t Au over 7.00 metres (including 16.15 g/t Au over 4.60 metres), 9.05 g/t Au over 1.0 metre, 1.26 g/t Au over 7.15 metres (including 2.70 g/t Au over 2 metres) and 0.53 g/t Au over 11.5 metres.

Hole CRO-22-151 was drilled 100 metres down dip of CRO-22-127ext, and hole CRO-22-152 was drilled to test mineralization along strike between CRO-22-128 and CRO-22-127ext. These holes both cut the basalt/gabbro sequence and wide zones of strong sericite-carbonate-pyrite +/- silica and fuchsite alteration. Several anomalous gold values were intersected including 1.65 g/t Au over 5.00 metres in CRO-22-151 and 2.03 g/t Au over 6.50 metres in CRO-22-152.

Mineralization in this western area has now been found along a strike length of approximately 450 metres and is open along strike in both directions and at depth. The results obtained to date in the NBD suggest that a large gold-bearing hydrothermal system is present, at least 1,400 metres long and 300 metres wide. Drilling has been largely exploratory, with holes approximately 100 metres apart, except for the Z120 area. Most of the NBD remains to be drill tested. The Company is currently evaluating the next phase(s) of exploration for this area.

Holes CRO-22-131 and 132 tested the east and west extents of the historic Croteau-Est Showing, which does not appear to have been previously drilled. Channel sampling at this showing by Northern Superior in 2012 returned gold values up to 4.83 g/t Au over 0.70 metres. The showing occurs on the north side of an area of low magnetic intensity, found to be coincident with carbonate-sericite alteration and quartz veining, which returned 4.37 g/t Au over 2.00 metres in hole CRO-22-131. Based on the geology and alteration present in these holes, CRO-22-135 was drilled directly beneath the Croteau-Est Showing and returned 5.13 g/t Au over 3.05 metres, within similarly altered material.

Holes CRO-22-137 through 148 tested the Z120 zone, found in holes CRO-22-120 (1.06 g/t Au over 26.30 metres, including 4.98 g/t Au over 3.00 metres) and CRO-22-114 (0.40 g/t Au over 19.25 metres) (see press release dated July 19, 2022). This work has successfully extended mineralization approximately 400 metres along strike to the east. Unfortunately, wet ground conditions prevented testing the zone to the west. The zone is interpreted to dip moderately to the south and appears to cross-cut local stratigraphy. Highlights of the drilling in this area include 12.82 g/t Au over 1.9 metres including 40.30 g/t Au over 0.60 metres in hole CRO-22-137, 0.67 g/t Au over 16.80 metres in CRO-22-141 and 1.31 g/t Au over 13.30 metres in CRO-22-147 (see Figure 5). This zone remains open along strike and at depth.CRO-22-149 was designed to test a grassroots target, where feldspar porphyry dykes intersect the interpreted Gwillim Fault. The hole encountered mafic volcanics intruded by feldspar porphyry dykes and sericite-carbonate alteration zones, which returned 1.87 g/t Au over 1.00 metre and 5.61 g/t Au over 1.50 metre.
