NGEx Minerals to Spin-Out Royalties to Shareholders

July 22, 2025 , Vancouver, British Columbia – NGEx Minerals Ltd. (“NGEx”, “NGEx Minerals” or the

“Company”) (TSX: NGEX; OTCQX: NGXXF) is pleased to announce plans to spin -out net smelter return

(“NSR”) royalties on the Lunahuasi and Los Helados Projects by way of a statutory plan of arrangement

under the Canada Business Corporations Act (the “Arrangement”).

Highlights

• Create a 1% NSR royalty on the 100% owned Lunahuasi Project, located in San Juan Province

Argentina.

• Intends to create a 2% NSR royalty on the Los Helados Project located in Region 3 , Chile, with a

1.38% NSR to be allocated to a newly incorporated, wholly-owned subsidiary (“RoyaltyCo”) and a

0.62% NSR to be allocated to Nippon Caserones Resources LLC (“ NCR”), a subsidiary of JX

Advanced Metals Corporation , based on each company’s respective pro-rata interest in Los

Helados of approximately 69% and 31%.

• Shareholders of NGEx will vote on the Arrangement at a special meeting to be held on September

12, 2025. The Arrangement will also be subject to Toronto Stock Exchange and court approval.

• If approved, shareholders of NGEx will receive 1/4 of a share of RoyaltyCo for each share of NGEx

held as of the Record Date (as defined below).

• 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.

Wojtek Wodzicki, President and CEO, commented, “NGEx and its predecessor companies have an

extremely strong track record of creating very significant value for shareholders through spin-outs and an

entrepreneurial, value-driven approach to managing its assets. Today’s announcement marks the next

step in that ongoing journey. If approved, this transaction is expected to provide NGEx shareholders with

long-term exposure to Lunahuasi and Los Helados through RoyaltyCo, which intends to apply to list its

shares for trading on the TSX V following completion of the Arrangement . In addition, through NGEx’s

anticipated holding of up to a 19.9% interest in RoyaltyCo, NGEx itself will also retain future exposure to a

vehicle that is expected to use the royalties to spearhead future portfolio growth and diversification . We

plan to put an experienced management team and board in place with a mandate to drive a growth

strategy and build RoyaltyCo into a significant new player in the royalty space.”

Summary

The Company has entered into a royalty purchase agreement with a newly incorporated wholly -owned

subsidiary of the Company (“ RoyaltyCo”) pursuant to which NGEx will cause a 1.0% NSR royalty on the

Nacimiento I concession, located in San Juan Province, Argentina, on which the Company’s 100% owned

Lunahuasi Project is currently defined, to be granted to RoyaltyCo (the “Lunahuasi Royalty”) in exchange

for cash consideration. In addition, the Company also intends to cause its wholly-owned subsidiary which

holds the Los Helados Project , located in Region III, Chile, on behalf of an unincorporated joint venture

between the Company and NCR, to enter into royalty purchase agreements with each of RoyaltyCo and

NCR to cause a combined 2.0% NSR royalty to be granted on the concessions underlying the Los Helados

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

the associated aggregate cash consideration, will be allocated to RoyaltyCo and NCR based on the

Company and NCR’s respective pro rata interest 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.

Concurrent with the foregoing, NGEx has also entered into an arrangement agreement with RoyaltyCo

(the “Arrangement Agreement”), whereby, among other things, the common shares of RoyaltyCo (the

“RoyaltyCo Shares”) will be spun-out to the shareholders of NGEx (the “ NGEx Shareholders”) by way of

a statutory plan of arrangement under the Canada Business Corporations Act. As part of the spin -out of

the RoyaltyCo Shares to NGEx Shareholders, NGEx also expects to make a cash injection into RoyaltyCo.

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 Lunahuasi and Los Helados projects. Over time, it is expected that RoyaltyCo may

add new and additional royalty interests to its portfolio.

Terms of the Arrangement

The Arrangement involves, among other things, the distribution of RoyaltyCo Shares to NGEx

Shareholders such that each NGEx Shareholder as of a particular date, immediately prior to closing of the

Arrangement (the “Record Date”) will receive 1/4 of a RoyaltyCo Share for each common share of NGEx

(each, a “NGEx Share”) held as of the Record Date. There will be no change in the NGEx Shareholders’

holdings in NGEx as a result of the Arrangement. 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 on a pro-rata basis as described above.

Each outstanding stock option of NGEx (each, a “NGEx Option”) will be exchanged for a replacement stock

option of NGEx (each, a “NGEx Replacement Option”) and a fully-vested stock option of RoyaltyCo (each,

a “ RoyaltyCo Option”) exercisable for 1/4 of a RoyaltyCo Share , and the exercise prices for the NGEx

Replacement Options and the RoyaltyCo Options will be adjusted to reflect the relative value of the

shares.

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

(the “Meeting”). To be effective, the Arrangement must be approved by a special resolution passed by at

least 662/3% of the votes cast by NGEx Shareholders present in person or represented by proxy and entitled

to vote at the Meeting, which NGEx Shareholders are entitled to one vote for each NGEx Share held.

Completion of the Arrangement will also be subject to Toronto Stock Exchange and court approval. Full

details of the Arrangement will be included in the management information circular (the “Circular”) that

will be mailed to NGEx Shareholders in connection with the Meeting.

The Circular will propose an experienced senior management team and board of directors for RoyaltyCo.

Further details regarding the proposed management team and board of directors of RoyaltyCo will be

described in the Circular.

After careful consideration, the Board of Directors has unanimously determined that the Arrangement is

fair to NGEx Shareholders and is in the best interests of the Company. A description of the various factors

considered by the Board of Directors in arriving at this determination will be provided in the Circular.

Following completion of the Arrangement, the NGEx Shares will continue trading on the TSX under the

symbol “NGEX” and on the OTCQX under the symbol “NGXXF”. RoyaltyCo intends to apply to list the

RoyaltyCo Shares on the TSXV shortly following completion of the Arrangement. Readers are cautioned

that, while RoyaltyCo intends to pursue a listing on the TSXV shortly following completion of the

Arrangement, it has not yet submitted an application for listing, and completion of a listing is subject to

regulatory approvals and the satisfaction of all of the applicable listing requirements of the TSXV. There

can be no assurance that a listing will be completed, and RoyaltyCo may elect not to proceed with a listing

at any time in its sole discretion.
