NGEx Reports Q1 2025 Results;

Successful Phase 3 Campaign Reinforces Lunahuasi’s Unique Potential

May 9, 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 months ended March 31, 2025 (“Q1

2025”).

Highlights for Q1 2025 and the subsequent period thereto, include the following, details of which are discussed

further below:

- Phase 3 drilling showcases the significant scale of Lunahuasi’s high-grade mineralization. Phase 3 drilling

continued to intersect high-grade copper, gold and silver mineralization across considerable widths within

all drillholes completed and assayed to date. The high -grade mineralization was encountered across our

full target scale, from short-range infill holes to longer-range step out holes.

In addition, mid - and long -range step out holes completed and assayed to date have substantially

extended the minimum dimensions of the mineralized volume at Lunahuasi to 1.2km north-south, 1.7km

east-west, and 1.2km vertically, with the deposit remaining open in all directions. Of note, additional step

out holes are still pending assay, which could further expand the mineralized volume at Lunahuasi. By

comparison, prior to the undertaking of Phase 3 drilling, the minimum dimensions measured 400 metres

north-south, 900 metres east-west, and 960 metres vertically.

- Now completed Phase 3 drill program has resulted in improved geological understanding at Lunahuasi.

The Company has improved its understanding of the geological setting at Lunahuasi, specifically increasing

its confidence that the high -grade vein mineralization is correlated to, and controlled by, individual

northeast trending, steeply dipping, structural corridors. This insight will be critical as the Company plans

to focus future exploration on this high-value mineralization.

- Gold grades intersected at Lunahuasi comparable to the world’s top tier gold-only deposits. Throughout

the high-grade vein hosted mineralization, the Company has intersected several intervals of exceptional

gold values that would rival even top-tier gold-only deposits found globally, such as 27.4m at 23.17 g/t Au

in hole DPDH032, which are in addition to high-grade copper and silver values. The Company believes that

over time, as more drilling is conducted, gold has the potential to become a significant part of Lunahuasi’s

value proposition.

Wojtek Wodzicki, President and CEO, remarked, “Although final assays from the Phase 3 Lunahuasi program are

still coming in, results received to date have already contributed to a step change in our understanding of the

deposit and the campaign has been a resounding success. In addition to consistently delivering high-grade copper,

gold and silver intercepts from short -range infill holes to our longest-range step out holes, Phase 3 drilling at

Lunahuasi has rapidly expanded the minimum north-south, east-west and vertical distances of the mineralized

volume to well over 1km. This unique combination of high-grades and significant scale strongly emphasizes the

potential exhibited by the vein hosted mineralization at Lunahuasi.

Another key takeaway from the Phase 3 program has been the g old content at Lunahuasi, which continues to

surprise to the upside. Several drill holes have intersected gold grades and widths comparable to those observed in

some of the world’s highest-grade gold mines. The emerging gold story at Lunahuasi is often overshadowed by

copper grades, but the deposit’s gold may prove to be a significant part of its future value proposition.

Having achieved our objectives for the Phase 3 program, drilling for the season has now ended, with final

demobilization now underway and on track to be wrapped up before the arrival of winter weather conditions at

the project. While we will continue to advance the remaining samples from Phase 3 through the assay process, our

cash position remains strong and focus has already turned to interpretation of all the data collected during this

recent campaign and planning for a Phase 4 Lunahuasi program to begin in the latter half of the year. We look

forward to releasing the final assay results from Phase 3 over the coming months and providing an overview of our

exciting Phase 4 plans for Lunahuasi in the third quarter.”

Q1 2025 Operating Highlights and Outlook

NGEx Successfully Completes Phase 3 Program at Lunahuasi

The Company’s primary focus for the three months ended March 31, 2025 was the execution and expansion

of its Phase 3 drill program at Lunahuasi, located in San Juan, Argentina. Phase 3 drilling began in October 2024

and, in response to the program’s early success, was expanded from six to eight rigs in February 2025 ,

increasing the campaign’s targeted drill metres to 25,000m.

Phase 3 drilling was successfully completed in early May 2025, with over 25,000 metres completed in 24 holes,

including three geotechnical holes designed to support the Company’s analysis of a potential underground

exploration adit at Lunahuasi. 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.

During the three months ended March 31, 2025, and up until the date of this new s release, four sets of assay

results from the Phase 3 drill program have been released by the Company, in addition to the first set of Phase

3 assays released in December 2024. Highlights from the Phase 3 assays released thus far in 2025 include:

• Continuation of high-grade intersections across considerable widths within drillholes at all three target

scales for which assays have been received to date. Highlights include:

o DPDH028 which intersected 51.10m at 13.84% CuEq (5.98% Cu, 9.70 g/t Au, 90.4 g/t Ag);

o DPDH032 which intersected 27.40m at 25.19% CuEq (7.80% Cu, 23.17 g/t Au, 55.9 g/t Ag)

including 8.60m at 15.80% Cu, 69.82 g/t Au and 127.4 g/t Ag; and

o DPDH035 which intersected 51.5m at 12.26% CuEq (including 10.42 g/t Au) including 21.50m

at 23.81% CuEq (including 23.81 g/t Au);

• Improved confidence in geological understanding of high-grade vein hosted mineralization . The

correlation of the high-grade mineralization along individual northeast trending, steeply dipping, structural

corridors represents a significant step change in the geological interpretation of Lunahuasi, and will

facilitate planning of future programs as the Company looks to advance exploration around the priority

high-grade vein hosted mineralization;

• Significant expansion of the Lunahuasi deposit with successful mid- and long-range step out holes that

have extended the minimum distances of the mineralized volume from 400 metres north-south, 900

metres east-west, and 960 metres vertically at the end of Phase 2 to at least 1.2km north-south, 1.7km

east-west, and 1.2km vertically. While full assays for the largest step-out holes of Phase 3, DPDH027 and

DPDH029, are still pending, highlighted results from the largest step-outs assayed to date are summarized

are as follows:

o DPDH028, the best hole drilled to date at Lunahuasi, which was drilled deeper and to the west of

all previous holes;

o DPDH029, which was drilled 470m south of DPDH028 and returned 157.7m at 2.18% CuEq (1.67%

Cu, 0.49 g/t Au, 16.7 g/t Ag); and

o DPDH033, which extended the deposit 50m to the north with 16.25m at 6.79% CuEq (5.05% Cu,

1.87 g/t Au, 42.5 g/t Ag) plus 23.00m at 4.49% CuEq (2.34% Cu, 2.51 g/t Au, 35.6 g/t Ag) and

40.00m at 7.02% CuEq (2.23% cu, 6.02 g/t Au, 45.6 g/t Ag);

• Presence of elevated high-grade precious metals, particularly gold, with several intersections rivaling

renowned world-class, high-grade gold only deposits. Notable examples include:

o DPDH025 with 5.74m at 19.13 g/t Au;

o DPDH028 with 8.20m at 39.11 g/t Au, within a broader interval of 51.10m at 9.70 g/t Au;

o DPDH032 with 27.4m at 23.17 g/t Au;

o DPDH033 with 1.10m at 151.5g/t Au, within a broader interval of 10.1m at 19.32 g/t Au; and

o DPDH035 with 51.50m at 10.42 g/t Au, including 21.50m at 23.81 g/t Au.

Demobilization of equipment and personnel from Lunahuasi is now underway and anticipated to be completed

prior to the arrival of winter weather conditions at site. With the Company’s attention now shifting away from

the field, a key near-term focus will be the advancement of Phase 3 samples through the assay laboratory,

which will provide a steady flow of updates in the coming weeks. As of the date of this news release, full assay

results have been released for 10 holes DPDH024 to DPDH026, DPDH028, DPDH030 to DPDH035) and partial

assays have been released for an additional two holes (DPDH027 and DPDH029), representing approximately

53% of drill metres completed during Phase 3 . The remaining assay results from Phase 3 will be released as

they are received, analyzed, and confirmed by the Company.

During the second quarter of 2025, the Company will also begin compilation and analysis of the geological data

collected during the successful Phase 3 campaign and refining the geological model at Lunahuasi. Planning for

the Company’s next exploration program at Lunahuasi will also begin , with a Phase 4 start date currently

anticipated to be around October 2025.
