NGEx Receives Environmental Approval for Development of an Exploration Adit

at Lunahuasi

March 9, 2026, Vancouver, British Columbia – NGEx Minerals Ltd. (“NGEx”, “NGEx Minerals” or the

“Company”) (TSX: NGEX; OTCQX: NGXXF) is pleased to announce that the Mining Authority of San Juan

Province, Argentina, has approved the Environmental Impact Statement (“DIA”, or Declaración de Impacto

Ambiental) for the development of an exploration adit at the Company’s 100%-owned Lunahuasi project,

the highest-grade copper-gold-silver deposit in the Vicuña District.

The approval of the DIA represents a major milestone in what has been a swift permitting process and

enables NGEx to rapidly advance the Lunahuasi story, enabling underground evaluation and enhancement

of the Company’s geological understanding of this deposit.

Wojtek Wodzicki, President and CEO, commented, “We are very pleased to receive environmental

approval for the Lunahuasi exploration adit. This decision by the San Juan Mining Authority supports our

strategy of responsibly advancing Lunahuasi and underscores the strong working relationship we have

developed with provincial authorities.

The ability to proceed with underground development is a crucial step that will allow us to directly access

high-grade bulk material for metallurgical and engineering studies, provide access for year -round

underground drilling, improve geologic definition, and position Lunahuasi for the next stage of

advancement. This approval is also an important signal from San Juan and Argentina, reflecting their

commitment to responsible mineral development and the economic opportunities that it brings.”

Next Steps for Lunahuasi

With receipt of the DIA, the Company will now move forward with required preparatory work for the

exploration adit, including detailed engineering, contractor selection, preparation of surface facilities, and

other on -site readiness activities. Additional sectoral permits will continue to be progressed in

coordination with provincial and national authorities. NGEx is targeting the fourth quarter of 2026 to start

underground development subject to timely receipt of the remaining permits.

Underground access will provide the platform for definition drilling, metallurgical sampling, and

geotechnical assessment - key inputs to future technical studies and project evaluation.

As preparations, plans and designs are finalized, the Company will obtain all final requisite internal

approvals and secure additional insurance coverage for the underground development, as necessary.
