The Fort Worth Press - Northern Superior Identifies Broad High-Grade Zone at Philibert with Strong Step-Out Results Including 31.0 Metres at 1.94 g/t Au and 19.7 Metres at 2.03 g/t Au

HighlightsInclude (Grades uncut; lengths measured along hole; Table 1):

• PB-25-475: 1.94 g/t Au over 31.0 metres located under current resource pit from the Grey Fox footwall ("FW"), and 1.73 g/t Au over 6.1 metres located under current resource pit from the Grey Fox hanging wall ("HW");

• PB-25-477: 2.03 g/t Au over 19.7 metres; located below current resource pit from the Grey Fox FW; and

• New Core Area Outside of Current Resource Pit: The holes reported today, PB-25-475 and PB-25-477, coupled with previously reported hole PB-25-476, which intersected 2.89 g/t Au over 10.6 meters (see press release dated March 3, 2025), outline a new core area with all holes intersecting the Grey Fox FW zone along a strike of 150 metres and up to 200 metres vertically; all 3 holes are outside the current resource pit; this target remains open along strike and at depth.

"Today's exciting results, including 1.94 g/t over 31 metres in hole PB-25-475and 2.03 g/t over 19.7 metres in hole PB-25-477, continue to demonstrate the expansion potential of the Philibert deposit with three holes (475, 476, and 477) returning robust grades and excellent continuity beyond the current pit shell. These results further strengthen the steady progress made in expanding the mineralization at the southeastern extent of the pit, where we recently reported significant on-strike mineralization outside of the current 3 km-long resource pit, including 2.60 g/t over 26.5 metres in hole PB-24-448 and 3.59 g/t over 7.7 metres in hole PB-24-450, located approximately 200 metres and 800 metres east of the resource pit, respectively. These findings support the strong expansion potential beyond the current resource of 1,708,800 oz inferred at 1.1 g/t and 278,900 oz indicated at 1.1 g/t.⁵ The continued progression of Philibert reinforces its position as a cornerstone of the rapidly emerging Chibougamau Gold Camp," said Simon Marcotte, President and Chief Executive Officer

Unlocking Higher-Grade Gold Historically Considered Underground

A 1991 study evaluating the economic potential of the Philibert Project focused exclusively on underground resources in the western domains, identifying approximately 239,000 ounces at 5.68 g/t gold (this resource is not NI 43-101 compliant).² In contrast, the mineral resource estimate published by Northern Superior in 2023 did not include any underground potential, as it was limited to an open-pit assessment.

As the Company continues to successfully expand the Philibert mineralization, widening the pit not only increases its lateral extent but consequently allows for greater depth. An expanded pit design with greater depth could enable the capture of higher-grade mineralization, which was so far considered to have underground potential only (see Figure 3 and Figure 4). The disseminated mineralization, occurring over broad widths with significant grades-along with higher-grade shoots as identified in drill holes from this release-is being analyzed using new geological and structural data to refine the mineralization model and identify potential resource expansions.

Drilling Results

Drill holes PB-25-475 and PB-25-477 successfully targeted the Grey Fox FW zone approximately 80 metres below the current resource pit, 175 metres vertical depth, and 150 metres along strike. These results confirm that mineralization extends at depth and along strike, demonstrating both higher-grade intervals and broader zones of lower-grade mineralization. (See Figure 1 for a plan map of the drilling and Table 1 for a list of significant results.)

Drill hole PB-25-475 returned 1.94 g/t Au over 31.0 metres, including 5.93 g/t Au over 2.0 metres, 5.01 g/t Au over 3.0 metres, and 28.0 g/t Au over 1.0 metre from the Grey Fox FW zone. This interval is approximately 150 metres along strike from PB-25-477, which returned 2.03 g/t Au over 19.7 metres, including 5.02 g/t Au over 7.1 metres. Previously reported hole PB-25-476, located between PB-25-475 and PB-25-477, returned 2.89 g/t Au over 10.6 metres, including 5.15 g/t Au over 5.3 metres from the Grey Fox FW (see press release dated March 3, 2025). These results demonstrate impressive continuity with significant grades and widths. Mineralization in the footwall is hosted within the siliceous phase of the Philibert gabbro seam, characterized by pervasive silica and quartz-veining with variable amounts of ankerite, sericite, and disseminated pyrite-pyrrhotite (1-15% abundance). (See Figure 3 for a longitudinal view of the FW zone, Figure 4 for a section view, and Figure 6 for a core photo of PB-25-477.)

The interpreted Grey Fox HW zone was tested with hole PB-25-475, which returned 1.73 g/t Au over 6.1 metres, including 4.99 g/t Au over 1.4 metres. Previously reported drill hole PB-25-476 returned 2.5 g/t Au over 8.4 metres, including 6.47 g/t Au over 1.7 metres, while PB-25-477 returned 0.98 g/t Au over 2.8 metres. The drill holes were primarily designed to test beneath the resource pit of the FW zone rather than target hanging wall mineralization. Mineralization in the HW zone represents a litho-structural contact between the Philibert gabbro seam and mafic volcanics, and locally with interbedded sediments, including graphitic argillite. The zone exhibits strong deformation, fracturing, and sulphide mineralization with smoky quartz and quartz-tourmaline veins. (See Figure 4 for a section view, and Figure 5 for a longitudinal view of the HW zone.)

Today's drilling results continue to highlight the potential to expand the pit northward by incorporating the HW zone, while also extending mineralization at depth within the FW zone. Although the FW zone is better understood, the geological team is actively studying the HW and their structural relationships to refine and enhance the mineralization model.

Intersections are determined using 0.2 g/t Au cut off and no more than 10 metres of consecutive dilution. Grades are presented uncut. If an intersection is 1 metre or less dilution under 0.2 g/t Au may be used to determine a 2-metre intersection.

The Chibougamau Gold Camp

The Chibougamau Gold Camp is rapidly emerging as one of the world's most sought-after gold destinations with several complementary gold resources reaching viable scale. In recent years, these critical assets were divided amongst five different companies. Today, largely due to Northern Superior's acquisitions and corporate transactions,³ ownership has been streamlined, with only IAMGOLD and Northern Superior holding these assets. The proximity of these deposits to each other makes them ideally suited to feed a single mill, and their consolidation enhances their viability, thereby increasing their value.

Below is a table showing the resources of the camp having been formalized to date.

Note: see NI-43-101 information below in notes 4, 5, 6, and 7.

³ Including Northern Superior acquisitions of Genesis Metals Corp. and Royal Fox Gold Inc.
