NORSEMONT PROVIDES CORPORATE UPDATE AND ADDITIONS TO

THE TEAM

Vancouver, B.C., October 21, 2025 – Norsemont Mining Inc. (CSE: NOM, OTC: NRRSF, FWB:

LXZ1) (“Norsemont” or the “Company”) is pleased to provide a corporate update highlighting

recent milestones and upcoming initiatives at its 100%-owned Choquelimpie project in northern

Chile having recently raised $6 million from strategic investors.

The Choquelimpie project is a past-producing gold-silver mine with historical heap leach

production. On April 14, 2025, the Company published its initial mineral resource estimate of

2,184,000 indicated gold-equivalent ounces and 557,000 inferred gold equivalent ounces in

oxide stockpiles and deeper sulfides. The project benefits from extensive infrastructure including

power, water, road access, camp facilities, and a 3,000 tonne-per-day mill positioning it for rapid

advancement toward production and cash flow.

Development Strategy

Norsemont has a two-pronged development plan.

1) Process stockpiles to drive initial positive cash flow.

2) Systematically drill and expand the oxide and sulfide resources, while testing the copper

porphyry potential deeper in the system.

Current Work Programs

To accomplish these objectives the Company is doing the following:

Oxide processing:

• Develop a geological model for stockpiles and in-situ oxides – In progress

• Define metallurgical characteristics of the above – In progress

• Assess state of existing plant and refurbish as necessary – In progress

• Evaluate structural controls on oxide mineralization through drilling – up coming

Sulphide resource:

• Drill deeper high-grade targets, utilizing historical data to increase the sulphide resource

– up coming

Copper porphyry:

• Further assess the identified copper and gold porphyry systems situated below the

sulphide gold mineralization – up coming

Key Achievements to Date

• Raised $6 million to fund drilling and metallurgical programs from strategic investors.

• Expanded technical and management team with key appointments:

o David Flint – Chief Geologist: Over 35 years of experience, including as VP

conduct metallurgical assessments and support testing strategies. AGS Cotecna serves

clients including Antofagasta Minerals, Enami, T eck CDA, Gold Fields Salares, and others,

and was recently awarded the laboratory contract for Minera Fénix (Rio2).

• Permitting and Environmental Advisory: DAES Consultores (www.daesconsultores.cl)

Near-Term Objectives (Next 6 Months)

• Commence 2025 Phase 3 drill program

o Norsemont’s geological team refined and prioritized drill targets under the

supervision of David Flint and Roman Flores. Quotations from drilling and

analytical contractors have been received, and preparations are underway to

initiate the 2025 drilling program.
