NGEx Reports 2025 Results;

Solidifies Lunahuasi as a Globally-significant High-grade System;

Announces New Board Appointment

March 19, 2026, Vancouver, British Columbia – NGEx Minerals Ltd. (“NGEx Minerals” “NGEx ” or the

“Company”) (TSX: NGEX) (OTCQX: NGXXF) is pleased to report its results for the three months and year ended

December 31, 2025.

Summary of Highlights

Highlights for the three months and year ended December 31, 2025, and subsequent period thereto, include

the following, details of which are discussed later in the release:

- 8-rig drill program underway at Lunahuasi, following multiple new discoveries made during Phase 3

program completed earlier in the year. The Company’s Phase 4 drill program at Lunahuasi commenced in

October 2025 and reached steady-state drilling with eight rigs by mid -November. To date, the Phase 4

campaign has completed approximately 88% of its targeted 25,000 metres, with assay results received and

released thus far confirming the system’s high grades, size and continuity. The current campaign is planned

to continue until May 2026, and builds on a highly successful Phase 3 program completed in 2025, which

confirmed two new discoveries at Lunahuasi, a copper-gold porphyry system and a unique style of

mineralization comprised of ultra high-grade gold in quartz veins, in addition to significantly extending and

defining the high-grade copper, gold and silver vein mineralization that comprises the original discovery.

- Environmental approval received for a proposed Lunahuasi exploration adit. In March 2026, subsequent

to the 2025 year-end, NGEx Minerals received approval from the Mining Authority of San Juan Province,

Argentina, for a proposed exploration adit at the Lunahuasi project. Approval of the Environmental Impact

Statement (“DIA”, or Declaración de Impacto Ambiental) for the adit, is a crucial next step in the Lunahausi

story, which will enable the Company to proceed with underground development once additional sectoral

permits are received. When complete, the adit is expected to provide a platform to conduct exploration

and definition drilling, metallurgical sampling, and geotechnical assessment, which are all key inputs for

future technical studies and project evaluation. The approval significantly increases NGEx’s optionality for

future exploration and development at the project.

- Treasury strengthened with oversubscribed $175 million private placement. On October 15, 2025, the

Company closed a non-brokered private placement of common shares, successfully raising gross proceeds

of $175 million. The financing was upsized from its initial amount of $100 million in response to strong

investor demand. Net proceeds from the financing further bolster ed the Company’s strong treasury

position, which consisted of $132.1 million in cash and short-term investments as at September 30, 2025.

Net proceeds from the financing will fund the Company’s activities well beyond its current work programs,

as well as provide financial flexibility to expand the current Lunahuasi campaign or undertake additional

work, such as the development of an exploration adit.

- Spin-out of royalty company to shareholders. On October 23, 2025, the Company closed its spin -out of

an 80.1% ownership interest in LunR Royalties Corp. (“LunR”) to its shareholders by way of a statutory plan

of arrangement under the Canada Business Corporations Act such that effectively, among other things,

each registered shareholder of common shares of NGEx would receive 1/4 of a common share of LunR for

each common share of NGEx held as of end of day on October 22, 2025 . LunR was incorporated by the

Company in July 2025 as a wholly-owned subsidiary, which acquired a 1.38% net smelter returns (“NSR”)

royalty on the concessions underlying the Company’s Los Helados project in Chile (the “LunR-Los Helados

Royalty”) and a 1% NSR royalty on the Argentine concession on which the Lunahuasi deposit is current ly

defined (the “LunR-Lunahuasi Royalty”). Immediately following the closing of the spin-out, NGEx retained

13,370,107 common shares of LunR, representing a 19.9% ownership interest in LunR at the tim e, which

are still held by NGEx Minerals as at the date of this News Release.

Wojtek Wodzicki, President and CEO, commented, “We continue to build on NGEx and its predecessor companies’

track record of value creation, going from strength to strength in 2025. The spin-out of LunR to shareholders has

had a tremendous reception in the market, and our foresight in retaining a significant interest in the Lundin Group’s

debut royalty vehicle gives NGEx shareholders continued exposure to LunR’s success, while also affording the

Company with a liquid, valuable and non-dilutive financing tool for the future.

In addition, we have also continued to deliver on our core business of exploration in the rapidly-evolving Vicuña

district. Following a successful Phase 3 program at Lunahuasi completed in May 2025 that identified two new styles

of mineralization and significantly expanded the footprint of the deposit, Phase 4 drilling has now completed over

22,000 metres to date with results confirming the deposit’s unique combination of size and grade . With an

approved DIA now received for the proposed exploration adit and a strong treasury balance, we are looking forward

to successfully closing out the Phase 4 program and have already begun looking ahead to the next phase as we

continue to advance exploration at this remarkable deposit.”

NGEx Announces New Appointment to its Board of Directors

NGEx is also pleased to announce the appointment of Mr. Peter J O'Callaghan to its Board of Directors, effective

March 20, 2026. Mr. O'Callaghan was a Partner at Blake, Cassels & Graydon LLP for over twenty-five years, and

served as Office Managing Partner from 2018 until his retirement in December 2022. Mr. O'Callaghan's practice

encompassed all types of M&A and corporate finance transactions, with a focus on the mining sector. He holds

a Bachelor of Laws degree and a Bachelor of Commerce (Finance) degree from the University of British

Columbia. As a result of the changes, NGEx's Board of Directors will have a total of nine members.

2025 Operating Highlights and Outlook

Phase 4 Lunahuasi Program Builds on Highly Successful Phase 3 Campaign

In May 2025, the Company completed the Phase 3 drill program at its 100%-owned Lunahuasi project, located

in San Juan Province, Argentina, with 25,003 metres completed in 24 holes. Phase 3 highlights included:

• Delivery of some of the highest-grade copper, gold, and silver intercepts drilled globally in 2025;

• Consistent intersection of high-grade, high-sulphidation vein mineralization across considerable widths

and strike length, which significantly improved the Company’s geological understanding of three initial

zones, named Mars, Saturn and Jupiter , each representing a s ignificant volume of contiguous high -

grade mineralization. Additional significant intersections outside of these three zones point to the likely

presence of other discreet high-grade zones which have the potential to be defined with additional

drilling;

• Confirmation of two new discoveries at Lunahuasi, a new copper -gold porphyry system (see News

Release dated May 21, 2025) and ultra high-grade gold in quartz veins (see News Release dated July 8,

2025), which respectively represent the third and fourth distinct types of mineralization identified to

date at the project; and

• Expansion of the mineralized volume drilled to date at Lunahuasi to minimum dimensions of 1,100

metres by 1,200 metres by 1,200 metres, which remains open in all directions and is marked by high-

grade intercepts at the northern, southern and western boundaries of the drill pattern as of the

conclusion of the Phase 3 program.

Following the highly successful Phase 3 program, in October 2025, the Company launched its Phase 4 program

at Lunahuasi with six rigs. The Phase 4 program was ramped up to eight rigs by mid-November, and is expected

to continue until the program’s conclusion in May 2026, subject to weather. Phase 4 drilling has been designed

to further explore and define the four distinct styles of mineralization found to date at Lunahuasi, which include

disseminated and stockwork high -sulphidation copper-gold mineralization in addition to the three types of

mineralization identified above. The minimum 25,000-metre drill program will consist of three targeted ranges

of drill spacing to accomplish different objectives , including metres allocated to test new drill targets outside

the current drill pattern, namely:

• Short-range Definition: Define and expand the Mars, Saturn and Jupiter zones.

• Mid-range Step -out: Extend mineralized intersections and discover new high -grade zones in the

deposit beyond the three zones noted above.

• Long-range Exploration: Test anomalies and district scale targets to discover new components of the

Lunahuasi system and demonstrate its true potential.

To date, over 22,000 metres have been drilled, representing 88% of the target for Phase 4 , with initial holes

focusing on short-range definition and closer step-outs to test the geological interpretation and potential for

expansion of Lunahuasi’s Mars, Jupiter and Saturn zones. The Saturn zone was intersected by numerous holes,

including most notably DPDH048, DPDH051 and DPDH057, while holes such as DPDH054 and DPDH06 0

successfully tested the Mars Zone, and DPDH053 tested Jupiter (see News Releases dated December 17, 2025,

January 12, 2026 and February 10, 2026 ). Key highlights from the assays received and released thus far from

Phase 4 include:

• Saturn zone: Successful expansion and continued intersection of high-grades throughout

DPDH048 intersected 649.00 metres at 1.64% copper equivalent (“CuEq”) (0.73% Cu, 1.00 g/t Au, and 20.1

g/t Ag), including 126.55 metres at 5.09% CuEq (2.16% Cu, 3.30 g/t Au, and 59.2 g/t Ag) in the Saturn zone

100m below DPDH046 drilled during Phase 3.

DPDH051 intersected 327.40 metres at 3.74% CuEq (2.43% Cu, 1.53 g/t Au, and 21.8 g/t Ag), which is

punctuated by multiple very high-grade sub-intervals such as 7.30 metres at 14.50% CuEq (10.98% Cu,

2.49 g/t Au, and 193.3 g/t Ag) and 5.80 metres at 14.40% CuEq (11.97% Cu, 2.73 g/t Au, and 50.8 g/t Ag).

DPDH051 was drilled north to south to test the geometry of the Saturn zone perpendicular to most other

holes, and its results were consistent with the zone’s geological interpretation with high -grade gold

intervals correlating well with other holes.

DPDH057 successfully expanded the Saturn zone vertically above the mineralization intersected previously

in hole DPDH049, intersecting 131.00 metres at 5.09% CuEq (3.10% Cu, 2.03 g/t Au, and 58.2 g/t Ag) ,

including 30.00 metres at 7.91% CuEq (4.00% Cu, 4.58 g/t Au, and 64.5 g/t Ag) and 40.20 metres at 6.09%

CuEq (4.41% Cu, 1.48 g/t Au, and 68.8 g/t Ag).

• Mars zone: Outlining of a potentially very high-grade core within an expanding envelope

DPDH054 intersected 94.00 metres at 8.99% CuEq (3.88% Cu, 6.66 g/t Au, and 29.6 g/t Ag), including 21.70

metres at 31.92% CuEq (12.70% Cu, 25.21 g/t Au, and 95.5 g/t Ag). This wide and high -grade interval

correlates well with DPDH024 and DPDH035 completed during Phase 3 drilling, outlining the potential for

a very high-grade core to a much wider envelop of good grade.

DPDH060 successfully confirmed an interpreted extension of the Mars zone to the northeast by

approximately 70 metres, intersecting 32.30 metres at 4.95% CuEq (3.13% Cu, 2.18 g/t Au, and 26.5 g/t

Ag).

To date, 20 drill holes have been completed in Phase 4, with assay results released for 10 holes. Assay results

are now steadily being received, and will be released once analyzed and confirmed by the Company. Exact

timing will depend on drilling rates and assay turn-around times.

Environmental Approval Received on Proposed Lunahuasi Exploration Adit

Subsequent to the 2025 year-end, NGEx Minerals received an approval from the Mining Authority of San Juan

Province, Argentina, for the Environmental Impact Statement (“DIA”, or Declaración de Impacto Ambiental)

submitted for the proposed development of an exploration adit at Lunahuasi. The approval of the DIA

represents a vote of confidence by the Mining Authority of San Juan on NGEx’s commitment to responsible

mineral development. Underground access would provide a platform for deeper exploration drilling, tighter-

spaced definition drilling, access to high-grade material for metallurgical testwork and enable collection of

important information on geotechnical and groundwater conditions to inform future engineering studies. In

addition, an exploration adit would allow for year-round operations, where equipment and personnel would

be protected from winter weather conditions.

With receipt of the DIA, the Company is moving forward with required preparatory work for the exploration

adit, including detailed engineering, contractor selection, preparation of surface facilities, and other on -site

readiness activities. A geotechnical drillhole was completed along the centerline of the proposed exploration

adit as part of this work. Additional sectoral permits are required prior to the start of construction and these

will also 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 and regulatory and board approvals.

2025 Corporate Highlights

Completion of $175 Million Private Placement

On October 15, 2025, the Company closed an upsized non-brokered private placement, pursuant to which the

Company sold an aggregate of 7,000,000 common shares at a price of $25.00 per common share, generating

aggregate gross proceeds of approximately $175.0 million (the “Private Placement”). Share issuance costs

relating to Private Placement totaled $4.6 million, comprised primarily of $4.3 million relating to a 5.0% finders’

fees paid in cash on a portion of the Private Placement upon closing.

Net proceeds of the Private Placement will be used towards furthering exploration programs at the

Lunahuasi project, continued exploration and maintenance of the Company’s Los Helados project located in

Region III, Chile, as well as for general corporate and working capital purposes.

Completion of Spin-out of LunR Royalties

On July 14, 2025, the Company incorporated a wholly -owned subsidiary, LunR, for the purposes of acquiring

the 1.38% LunR-Los Helados Royalty and the 1% LunR-Lunahuasi Royalty, and ultimately undertaking a share

capital reorganization by way of a statutory plan of arrangement under the Canada Business Corporations Act

(the “Plan of Arrangement”) that resulted in the majority of the common shares of LunR (“LunR Shares”) being

distributed to shareholders of NGEx Minerals (“NGEx Shareholders”) (the “Arrangement”).

The Arrangement was approved by the NGEx Shareholders at the special meeting of NGEx Shareholders held

on September 12, 2025, and a final order approving the Arrangement was obtained from the Supreme Court

of British Columbia on September 18, 2025. Subsequ ently, the Arrangement was completed and became

effective at 12:01 a.m. on October 23, 2025 (the “Effective Time”), and involved, among other things, the

exchange of common shares and stock options of NGEx Minerals and the distribution of LunR Shares and stock

options of LunR, respectively, such that:

• Each common share of NGEx Minerals (each, a “NGEx Share”) outstanding at the close of business on

the business day immediately preceding the Effective Time was redesignated and exchanged as part of

a reorganization of the share capital of NGEx Minerals, and in accordance with section 86 of the Income

Tax Act (Canada), for (i) one (1) new common share of NGEX Minerals (each, a “New NGEx Share”),

which such New NGEx Share being identical to the NGEx Shares immediately prior to the Effective Time

and (ii) 1/4 of a LunR Share; and

• Each outstanding stock option of NGEx Minerals (each, a “NGEx Option”) that was outstanding

immediately before the Effective Time was exchanged for (i) one (1) replacement stock option of NGEx

Minerals (each, a “NGEx Replacement Option”) to purchase from NGEx Minerals one New NGEx Share

having an exercise price (rounded up to the nearest whole cent) equal to the product of the exercise

price of each NGEx Option so exchanged immediately before the Effective Time multiplied by the fair

market value of a New N GEx Share at the Effective Time divided by the total of the fair market value

of a New NGEx Share and the fair market value of 1/4 of a LunR Share at the Effective Time, and (ii)

one (1) fully-vested stock option of LunR (each, a “LunR Option”) to acquire 1/4 of a LunR Share, each

whole LunR Option having an exercise price (rounded up to the nearest whole cent) equal to the

product of the exercise price of the NGEx Option so exchanged immediately prior to the Effective Time

multiplied by the fair market value of 1/4 of a LunR Share at the Effective Time divided by the total of

the fair market value of one New NGEx Share and 1/4 of a LunR Share at the Effective Time.

Pursuant to the provisions above, it was determined that the exercise price of each NGEx Replacement Option

would remain the same as the respective, underlying NGEx Option for which it was exchanged pursuant to the

Arrangement.

In conjunction with the spin-out of the LunR Shares to NGEx Shareholders, NGEx Minerals also made a total

capital contribution into LunR in the amount of $4,350,000, which included funds used by LunR to acquire the

LunR-Los Helados Royalty and the LunR-Lunahuasi Royalty and for general working capital purposes. The capital

contributions by NGEx Minerals resulted in it receiving 13,370,107 LunR Shares in return, representing a 19.9%

ownership interest in LunR that has been retained and was not part of the spin -out to NGEx Shareholders.

Immediately following the completion of the Arrangement, an aggregate of 67,186,346 LunR Shares were

issued and outstanding.

LunR Shares commenced trading on the TSX Venture Exchange on December 19, 2025, under the symbol

“LUNR”.

The terms of the Arrangement can be found in NGEx’s management information circular dated August 12,

2025, which is available on NGEx’s website and under its profile on SEDAR+ at www.sedarplus.ca.
