NORSEMONT PROVIDES CHOQUELIMPIE DRILLING UPDATE

Vancouver, B.C., July 2 , 202 6 – Norsemont Mining Inc. (CSE: NOM, OTC: NRRSF, FWB: LXZ1)

(“Norsemont” or the “Company”) is pleased to announce an update on our 2026 phase III drill program.

Nine (9) holes, for a total of 2,187.15 meters (Figure 1 & Table 1), have been drilled year -to-date on the

Choquelimpie project. These holes have been designed to both step -out and offset from identified

mineralized intercepts.

Highlights

• Norsemont has completed nine drill holes totaling 2,187 meters so far in 2026, expanding work across

five key zones at Choquelimpie.

• Early drilling has helped outline the edges of several hydrothermal breccia bodies , giving the team

a clearer picture of where the strongest mineralization is likely to continue.

• Multiple gold-bearing styles have been confirmed, including Hydrothermal breccias, Porphyry-related

quartz ± magnetite veinlets and Quartz-mica-sulfide alteration zones

• Base-metal mineralization is present in the quartz-mica-sulfide zones, adding another potential value

component to the system.

• New holes now underway (DD -15 and DD-18) are offsetting from known mineralization, targeting

extensions in the Choque and Suri Zones.

• Assays are pending and expected to be meaningful catalysts once released.

• Metallurgical and 3D geological studies planned for later in 2026 will help refine the precious- and

base-metal relationships across the system, supporting future resource growth.

Management Comments

Norsemont CEO, Marc Levy commented:

“Phase III drilling continues to advance our understanding of the multi-zone gold-silver system at

Choquelimpie. The Phase III program has expanded mineralization across multiple zone areas,

and early results are helping refine the geometry of key breccia bodies and associated

porphyry-style mineralization. As additional assays come in, we are steadily improving the 3D

model of the system and identifying new offset opportunities for follow-up drilling. With multiple

mineralization styles confirmed and active work underway on geological, geophysical, and

metallurgical studies, Choquelimpie continues to demonstrate strong resource expansion potential

which will drive project growth.”

Drill Program Update

Two (2) of the holes (DD -09 & 10) have further explored the Choque Zone, one (1) the Suri Zone (DD -

08), three (3) the Vizcacha Zone (DD -11, 12 & 13) , one (1) the Hundimiento Zone (DD14) , and two (2)

holes for the Espanola Zone. Holes MV26-DD-15 and DD-18 are currently in progress, further exploring

the Choque and Suri Zones. Assays from the Phase 3 2026 drilling program will be reported once available.

Table 1

Some early 2026 holes seem to have defined the limits for individual hydrothermal breccia bodies.

Accordingly, future 2026 holes are being designed to offset from known mineralization.

Gold mineralization, of the following three (3) styles, has been intersected by the Phase 3 drilling:

• Hydrothermal breccia bodies,

• Dacite-andesite porphyry cut by quartz +/- magnetite veinlets,

• Quartz-mica-sulfide alteration zones developed on the dacite-andesite porphyry and some

hydrothermal breccia bodies.

• Additionally, the elevated base-metal mineralization appears to be primarily related to zones of

quartz-mica-sulfide alteration.

The mineralogical relationship between the precious - and base-metal mineralization will continue to be

assessed as part of metallurgical studies planned to be conducted on sulfide materials later in 2026. Also,

the three-dimensional spatial relationships between the various mineral intercept types are being analyzed

as additional data is received. The results of these studies, in conjunction with geological and geophysical

information, provides important data points to aid in interpretation of the evoluti on of the Choquelimpe

hydrothermal mineralizing system.

Split drill core samples for the drilling is being shipped to Activation Geological Services SpA (AGS) for

geochemical analysis. The samples are being prepared at the AGS facility located in Antofagasta Chile

and analyzed at the AGS geochemical laboratory, located at Coquimbo, Chile. The laboratory has an ISO

17025 certification. The gold grades are bein g determined by fire assay (AGS code AU -FA30). Drill

intervals that have some degree of oxidation are also analyzed by the cyanide-soluble gold method (AUCN).

The samples are also analyzed for 60 elements, including silver, by mass spectrometer (MS TD60). In

addition, silver and specific base metals are re -assayed by atomic absorption spectrometry (AGS code

4ACID-AAS) for samples where the initial value for a p articular element is greater than the limit of

accuracy (“over-limit”) for that method. The overlimit value for: silver (Ag) is 100 parts per million (ppm),

copper (Cu) is 10,000 ppm, lead (Pb) is 5,000 ppm and zinc (Zn) is 10,000 ppm.

Standard and blank samples are being inserted at a frequency of one each for every 20 drill samples.

The Phase 3 exploration program is being managed by Roman Flores, a Persona Calificada (Q.P.) with the

Commission Minera Chile.
