Norsemont Drilling Program Update at Choquelimpie

(TheNewswire)

Vancouver, B.C. – TheNewswire - December 2, 2025 – NorsemontMining Inc. (CSE: NOM, OTC: NRRSF, FWB: LXZ1) ( “ Norsemont ” or the “ Company ”) is pleased to announce completion of the initialdiamond drill hole and commencement of 2 additional drill holes ofits Phase 3exploration drill program at the100%-owned Choquelimpie high-sulfidationgold-silver-copper project in northern Chile. The first hole wastargeting higher-grade gold mineralization hosted in the Vizcachahydrothermal Brecia (Figure 1).  The Phase 3 program will comprise upto 5,000meters of diamond drilling (“DDH”) utilizing two (2) diamond drill rigs , withdrilling scheduled to continue through late December.

Highlights

• Diamond drill hole MV25-DD01, targeting the Vizcachahigher grade hydrothermal breccia, has been completed to a depth of300 meters (Figure 2).

• Diamond drill hole MV25-DD02 has been collared, fromthe same station as MV25-DD01 (Figure 1), to also target the VizcachaHydrothermal Breccia to depth (Figure 2)

• MV25-DD03 has been designed to explore the Choque Zone(Figure 1) at depth, below the area where gold grades have beencalculated within the 2025 resource model (Wilson, 2025), (Figure3).

Management Comments

Norsemont CEO Marc Levy commented:

“With the second and third diamond drill holes now inprogress at Choquelimpie utilizing 2 drill rigs, we are rapidlyadvancing what we believe could be a transformative Phase 3 drillprogram. The targeting of these holes reflects our growing confidencein the potential for substantial high-grade gold zones at depth andalong strike below the existing open-pit resource. We look forward tofurther updating shareholders as drilling continues and results becomeavailable.”

The Phase 3 Drill Program

The Phase 3 drill campaign at Choquelimpie is designedto evaluatedown-dip extensions of higher-grade goldmineralization (>1 gram/tonne Au) hosted within hydrothermal brecciazones . The program willcomprise up to 20 holesaveraging 250 meters in length. Thepriority drill stations for this program are shown on Figure1 .

Norsemont, through its wholly owned Chileansubsidiary SCMVilacollo , has engaged DV DrillingLtd. of Coquimbo, Chile, to conduct thePhase 3 exploration program. DV Drilling is operating one each of aGolden Bear 1400, and CSK C1500, truck-mounted diamond drills.  The rigs will be operated on a 24-hourschedule.

Drill core samples will be prepared at the Activation Geological ServicesSpA (AGS) facility located in Antofagasta Chileand analyzed at the AGS geochemical laboratory, located at Coquimbo,Chile.  The laboratory has an ISO 17025 certification.

Downhole surveys are being conducted by DV Drillingutilizing a Device Gyroscope.

Hole MV25-DD01 has been collared at coordinates ofE473,285, N7,975,980 and an elevation of 4,694 meters (blue star onFigure 1).  The hole, oriented at an azimuth of 275 degrees andinclined at 70 degrees, has been completed to a depth of 300 meters. The hole dominantly intersected the Vizcacha hydrothermal breccia(“Brecha Hidrotermal” in Figure 2), as predicted.  The brecciahosts moderate to strong pyrite mineralization (1 – 7%), asdisseminations and in veinlets.  Silica-pyrite and silica-enargiteveinlets also were intersected from the 180-meter depth to theend-of-hole.  Assays are pending

Hole MV25-DD02 has been collared,from the same station as MV25-DD01, to also target the VizcachaHydrothermal Breccia to depth (Figure 2).  The hole: is oriented atan azimuth of 180 degrees, is inclined at 80 degrees and has a designdepth of 225 meters. The hole is intersecting the VizcachaHydrothermal Breccia, with disseminated and veinlet-hostedsulfides.

Hole MV25-DD03 has been collared: at coordinates ofE472,622, and N7,975,811 (Figure 1), at anelevation of 4,735 meters, and with a design depth of 275 meters(Figure 3).  This drill hole targets the Choque Zone at depth, belowthe area where higher gold grades (red, pink & purple displaycolors on Figure 3) have been calculated within the 2025 resourcemodel (Wilson, 2025), (Figure 3).  This drill hole will alsointersect a modeled hydrothermal breccia body.

The Phase 3 exploration program is being supervised byRoman Flores, a Persona Calificada (Q.P.) with the Commission MineraChile.
