NGEx Reports Q2 2025 Results;

Porphyry and High-grade Gold Discoveries at Lunahuasi; Plan to Spin-out Royalties

to Shareholders

August 11, 2025, 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 and six months ended

June 30, 2025.

Highlights for three months ended June 30, 2025 (“Q2 2025”) and the subsequent period thereto, include the

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

- Highly successful Phase 3 drill program continued to grow the Lunahuasi deposit. The Company

successfully completed 25,003 metres of drilling in 24 holes during the Phase 3 drill program, confirming

two significant new discoveries:

Major new copper-gold porphyry system – Drillhole DPDH027 confirmed the presence of a predicted

copper-gold porphyry system at Lunahuasi, adjacent to the high -grade copper -gold-silver high -

sulphidation vein structures that were initially discovered at the project. The porphyry discovery opens

an entirely new dimension to the project, comprising a very large-scale exploration target which holds

the potential to significantly increase Lunahuasi’s long-term value.

Quartz veins with high-grade visible gold – Drillhole DPDH046 intersected two separate quartz veins

containing ultra high-grade free gold. This new style of mineralization is rarely seen in high-sulphidation

epithermal deposits but has accounted for a significant portion of the value at successful projects

developed worldwide where it is present , such as the El Indio mine located 150 kilometres to the

southwest. The exceptional gold grades intersected thus far suggest that substantial additional value

creation may be possible with in only a relatively small, mineralized volume, which greatly increases

the gold potential of the Lunahuasi deposit. The full extent of this new style of mineralization has not

yet been defined, and the Company will prioritize , among other things, follow-up drilling to test this

exciting new exploration target in the upcoming program.

- NGEx plans to spin -out royalties on its flagship assets to shareholders. On July 22, 2025, the Company

announced its intention to spin-out net smelter return (“NSR”) royalties on its Lunahuasi and Los Helados

Projects, that will be held by a wholly-owned subsidiary of NGEx (“RoyaltyCo”) by way of a statutory plan

of arrangement under the Canada Business Corporations Act (the “Arrangement”). If all requisite

approvals are obtained, including those required from NGEx sha reholders and the Toronto Stock

Exchange, each shareholder of NGEx will receive 1/4 of a share of RoyaltyCo for each share of NGEx held

as of the Share Distribution Record Date (as defined below) and NGEx will retain a 19.9% interest in

RoyaltyCo. RoyaltyCo intends to apply to list its shares on the TSX Venture Exchange (the “TSXV”) following

completion of the Arrangement. Such listing will be subject to it fulfilling all of the listing requirements of

the TSXV. The creation and spin -out of RoyaltyCo is designed to allow NGEx Shareholders to capture

additional long-term value from the Lunahuasi and Los Helados projects through the royalties, while NGEx

continues to focus on advancing the projects through further exploration efforts.

Wojtek Wodzicki, President and CEO, commented, “We take great pride in the outstanding value that NGEx and

its predecessors have unlocked and delivered to shareholders over the years through successful exploration and the

execution of thoughtful corporate transactions including past spin-outs that have created tremendous value for our

shareholders. Our work during this past quarter is the latest example of this continuing endeavor. Phase 3 drilling

at Lunahuasi has been a resounding success, with the final assays of the program confirming two new discoveries,

each having the potential to further augment what is already a remarkable deposit: a copper-gold porphyry system

and a new zone of quartz veins hosting ultra high-grade free gold. This past season of drilling at Lunahuasi has

reconfirmed the unique nature of the deposit, which continues surprising to the upside, and we are eager to get

back into the field in October to follow up on the findings of the recent campaign.

On the corporate front, we are advancing the previously proposed spin-out of royalty assets on Lunahuasi and Los

Helados. If completed, the Arrangement will continue to give shareholders exposure to our keystone assets in the

emerging Vicuña District, while also providing a ground level opportunity to participate in a new and exciting

investment opportunity in the royalty space that will be led by an experienced leadership team, that we have begun

to assemble, with a mandate to grow and diversify its portfolio.”

Q2 2025 Operating Highlights and Outlook

Successful Phase 3 Lunahuasi Program Results in Two New Discoveries

The Company successfully completed its Phase 3 drill program at Lunahuasi, located in San Juan, Argentina, in

early May 2025, with 25,003 metres completed in 24 holes, including three geotechnical holes designed to

support the Company’s analysis of a conce ptual underground exploration adit at Lunahuasi. The final assays

from the Phase 3 program were released by the Company on July 8, 2025.

The program accomplished its main objectives of testing the Lunahuasi deposit at three target scales:

• Long-range exploration holes (+300m spacing) were big step-outs that tested for significant extensions of

mineralization to the north, south, and west;

• Mid-range step out holes (50-300m spacing) explored for extensions of the mineralized zone in all

directions and started to fill in large gaps in the drill pattern; and

• Short-range infill holes (30-50m spacing) tested the short-range variability of mineralized structures and

high-grade zones and confirmed the main structural orientations.

Throughout the Phase 3 campaign, drillholes at all three target scales consistently intersected high-grade vein-

hosted mineralization across considerable widths and significantly contributed to improvements in the geological

understanding of the structures that form the original Lunahuasi discovery, which continue to be the near-term

exploration priority at the project. The final assay results from the Phase 3 program confirmed the discovery of a

new copper-gold porphyry system at Lunahuasi (see News Release dated May 21, 2025) and the discovery of a

third, distinct type of mineralization at the project with ultra high-grade visible gold in quartz veins (see News

Release dated July 8, 2025).

Drillhole DPDH027 was drilled across the high-sulphidation epithermal structures before discovering a new zone

of porphyry copper-gold mineralization at approximately 1,262 metres downhole. The hole was drilled to a final

depth of 2,005 metres, where it ended in mineralization, returning 1,619.4 metres at 0.87% copper equivalent

(“CuEq”) (0.52% Cu, 0.32 g/t Au, 13.2 g/t Ag) including a porphyry intersection of 743.00 metres at 0.56% CuEq

(0.44% Cu, 0.13 g/t Au, 2.3 g/t Ag), which included:

• 18.00 metres at 2.68% CuEq (2.46% Cu, 0.18 g/t Au, 10.3 g/t Ag); and

• 17.80 metres at 1.23% CuEq (1.01% Cu, 0.24 g/t Au, 5.5 g/t Ag).

While the full scale of the Lunahuasi porphyry system remains unknown, another Phase 3 drillhole, DPDH029,

ended in argillic alteration associated with the high-sulphidation system overprinting early porphyry veins, some

500 metres south of the intersection in DPDH027, illustrat ing the size potential of the porphyry discovery.

Importantly, this discovery has opened up an entirely new dimension to Lunahuasi and significantly increases the

long-term potential of the project.

Drillhole DPDH046 resulted in the discovery of ultra high-grade free gold in quartz veins, which is a new style of

mineralization at Lunahuasi. Highlights include:

• 2.20 metres at 142.27 g/t Au from 467.10m, plus

• 3.60 metres at 245.39 g/t Au from 520.00m

The discovery of this third distinct style of mineralization at Lunahuasi is potentially transformative for the project,

as several renowned mines around the world have been built around high-grade gold quartz veins. While the size

and extent of the quartz veins have yet to be confirmed, the remarkably high-grades observed in DPDH046 allude

to the possibility that a relatively small volume of this gold-dominant mineralization could add a substantial amount

of value to Lunahuasi. Following up on this third Lunahuasi discovery will be a key objective of the Company’s

upcoming Phase 4 drill program.

The Company is now completing its analysis of the geological data collected during the Phase 3 campaign and

refining the geological model at Lunahuasi. Planning for the Company’s upcoming Phase 4 exploration program

at Lunahuasi is well advanced, with a start date currently anticipated for around October 2025.

Further details, such as the copper equivalent formula, can be found in the “Qualified Persons and Technical

Notes” section of this news release.

Proposed Spin-out of NSR Royalties on Lunahuasi and Los Helados

The Company has caused a royalty purchase agreement to be entered into between a newly incorporated,

wholly-owned subsidiary (“RoyaltyCo”) and the subsidiary that currently holds the Nacimiento I concession,

which will result in a 1% NSR royalty on the Nacimiento I concession being granted to RoyaltyCo (the “Lunahuasi

Royalty”) in exchange for cash consideration. NGEx’s 100% owned Lunahuasi Project, as currently defined, is

located on the Nacimiento I concession.

In addition, another wholly-owned subsidiary of NGEx which holds the Los Helados Project, located in Region

III, Chile, on behalf of an unincorporated joint venture between NGEx and Nippon Caserones Resources LLC

(“NCR”), has entered into royalty purchase agreements with each of RoyaltyCo and NCR to cause a combined

2.0% NSR royalty to be granted on the concessions comprising the Chilean portion of the Los Helados properties

(the “Los Helados Royalty“) in exchange for cash consideration. The Los Helados Royalty, and the associa ted

aggregate cash consideration, will be allocated to RoyaltyCo and NCR based on the Company and NCR’s

respective pro rata interests in Los Helados of approximately 69% and 31%, resulting in RoyaltyCo’s portion of

the Los Helados Royalty amounting to a 1.38% NSR royalty.

The Company has also entered into an arrangement agreement with RoyaltyCo (the “Arrangement

Agreement”), whereby NGEx intends to complete a share capital reorganization by way of a statutory plan of

arrangement under the Canada Business Corporations Act, w hich will result in, among other things, at least

80.1% of the common shares of the RoyaltyCo (the “RoyaltyCo Shares”) being spun-out to the shareholders of

NGEx (the “NGEx Shareholders”). As part of the spin-out of the RoyaltyCo Shares to NGEx Shareholders, NGEx

will make an additional capital contribution into RoyaltyCo for working capital purposes, which is in addition to

the amounts to be injected by NGEx to fund the acquisition of the Lunahuasi Royalty and RoyaltyCo’s portion

of the Los Helados Royalty, which will also be made by way of a capital contribution. The capital contributions

by NGEx will result in it receiving a number of RoyaltyCo Shares in return representing up to a 19.9% ownership

interest in RoyaltyCo that will be retained and not form part of the spin-out to NGEx Shareholders.

The Arrangement Agreement describes the terms of the proposed arrangement (the “Arrangement”), which,

among other things, includes:

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

business day immediately preceding the effective date of the Arrangement (the “Share Distribution

Record Date”) will be redesignated and exchanged as part of a reo rganization of the share capital of

NGEx, and in accordance with section 86 of the Income Tax Act (Canada), for (i) one (1) new common

share of NGEX (each, a “New NGEx Share”), which such New NGEx Share will be identical to the NGEx

Shares immediately prior to the effective time of the Arrangement (the “Effective Time”) and (ii) 1/4

of a RoyaltyCo Share; and

• Each outstanding stock option of NGEx (each, a “NGEx Option”) that is outstanding immediately before

the Effective Time will be exchanged for (i) one (1) replacement stock option of NGEx (each, a “NGEx

Replacement Option”) to purchase from NGEx 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 NGEx

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 RoyaltyCo Share at the Effective Time, and (ii) one (1) fully -vested stock

option of the Company (each, a “RoyaltyCo Option”) to acquire 1/4 of a RoyaltyCo Share, each whole

RoyaltyCo 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 RoyaltyCo Share at the Effective Time divided by the

total of the fair market value of one New NGEx Share and 1/4 of a RoyaltyCo Share at the Effective

Time.

Completion of the Arrangement is subject to receipt of requisite NGEx Shareholder, Toronto Stock Exchange

and court approvals, the timing and receipt of which cannot be determined at this time. NGEx Shareholders

will vote on the Arrangement at a special meeting to be held on September 12, 2025.

Following completion of the Arrangement, NGEx is expected to hold up to a 19.9% ownership interest in

RoyaltyCo, with the remaining RoyaltyCo Shares being distributed to NGEx Shareholders as described above,

in accordance with their pro-rata interest in NGEx as of the Share Distribution Record Date.

RoyaltyCo intends to apply to list its shares on the TSXV following completion of the Arrangement. Such listing

will be subject to it fulfilling all of the listing requirements of the TSXV.

Additional details with respect to the Arrangement can be found in the Company’s News Release dated July

22, 2025, on SEDAR+ at www.sedarplus.ca and the Company’s website www.ngexminerals.com.
