NGEx Reports Q1 2024 Results;

Demonstrates Size and Grade Potential at Lunahuasi with Successful 2023-2024 Drill

Program

May 13, 2024, 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, 2024.

Operating highlights for the three months ended March 31, 2024, and subsequent period thereto, include the

following, details of which are discussed further below:

 Recently completed drill program at Lunahuasi successfully confirms size and grade potential of deposit;

o Assays to date continue to deliver bonanza-grade intersections, such as DPDH009 returning

62.0 metres at 6.98% copper equivalent (“CuEq”), including 26.1 metres at 13.36% CuEq, and

DPDH014 returning 184.2 metres at 4.61% CuEq, including 23.0 metres at 23.02% CuEq;

o In addition, drilling to date has also intersected longer intervals of mineralization at elevated

grades, such as DPDH013, which intersected 509.4 metres at 1.33% CuEq and DPDH018, which

intersected 429.4 metres at 2.31% CuEq.

 Graduation to the Toronto Stock Exchange in February 2024, followed by the Company’s common shares

commencing trading on the OTCQX in March; and

 Strong treasury balance of $63.5 million at March 31, 2024.

Wojtek Wodzicki, President and CEO, commented, “The Lunahuasi drill program has continued to deliver

mineralized intercepts that rank among the highest copper grades encountered globally in recent years. Our drill

results demonstrate the potential for a large volume of high-grade stockwork mineralization in addition to the

previously identified bonanza-grade veins. With its increasingly evident size potential, elevated grades, and central

location within the evolving Vicuña District, NGEx is positioning Lunahuasi as a significant asset with growing

strategic importance to the region’s future development. The potential for further discovery and expansion at

Lunahuasi remains strong with mineralization open in all directions.

With our objectives for the campaign accomplished, drilling for the season has now ended and our team has

demobilized from the field. Our focus over the coming weeks will be on processing the remaining core collected

from the final six holes of the 2023-2024 program and expediting the samples through the assay laboratory. At the

same time, NGEx will continue to update its geological interpretation of the Lunahuasi deposit, which will feed into

the development of an exploration strategy for Lunahuasi’s next program, set to begin early in the fourth quarter.”

Q1 2024 and Subsequent Period Highlights

NGEx Successfully Illustrates Size and Grade Potential at Lunahuasi; Looks Ahead to 2024-2025 Program

In April 2024, the Company finished the 2023-2024 Lunahuasi drill program (the “2023-2024 Lunahuasi

Program”), with 12,952 metres of drilling in 15 holes. The program, which began in mid-October 2023,

successfully extended the high-grade mineralization first intersected in last year’s discovery holes and also

drilled long intervals of stockwork mineralization, which has confirmed Lunahuasi’s size potential. To date, the

Company has identified two distinct styles of porphyry-related mineralization at Lunahuasi: bonanza-grade

vein mineralization and high-grade stockwork mineralization.

The presence of both styles of mineralization is consistent with the Company’s current geological interpretation

that drilling completed to date has intersected the peripheral parts of a porphyry copper-gold system at Lunahuasi.

The grades and thickness of the mineralization observed within drill holes completed at Lunahuasi are positive

indicators of the strength and potential of the system that is thought to be the source of these high-grade

structures.

Highlights from the vein mineralization intersected during the recently completed drill campaign include:

 DPDH009: 62.0 metres at 6.98% CuEq (3.75% Cu, 3.43 g/t Au, 83.2 g/t Ag), including:

o 26.1 metres at 13.36% CuEq (7.53% Cu, 5.83 g/t Au, 178.6 g/t Ag);

 DPDH010: 102.0 metres at 4.56% CuEq (2.45% Cu, 1.71 g/t Au, 97.3 g/t Ag), including:

o 62.6 metres at 5.84% CuEq (3.10% Cu, 2.09 g/t Au, 138.3 g/t Ag), including:

 9.4 metres at 12.10% CuEq (4.86% Cu, 4.49 g/t Au, 450.2 g/t Ag); and

 DPDH014: 184.2 metres at 4.61% copper equivalent (“CuEq”) (2.85% Cu, 2.15 g/t Au, 22.3 g/t Ag),

including:

o 71.9 metres at 9.63% CuEq (5.79% Cu, 4.70 g/t Au, 46.9 g/t Ag), including:

 23.0 metres at 23.02% CuEq (14.68% Cu, 9.95 g/t Au, 123.1 g/t Ag).

Highlights from the high-grade stockwork mineralization intersected during the 2023-2024 Lunahuasi Program

include:

 DPDH010: 460.9 metres at 1.09% CuEq (0.64% Cu, 0.35 g/t Au, 22.2 g/t Ag);

 DPDH013: 509.4 metres at 1.33% CuEq (0.75% Cu, 0.55 g/t Au, 19.6 g/t Ag);

 DPDH015: 328.0 metres at 1.10% CuEq (0.73% Cu, 0.30 g/t Au, 16.4 g/t Ag); and

 DPDH018: 429.4 metres at 2.31% CuEq (1.41% Cu, 0.67 g/t Au, 46.6 g/t Ag).

Select drilling and assay results from the 2023-2024 Lunahuasi Program as noted above are summarized in

Appendix 1 to this news release. Drilling and assay results from the 2023-2024 Lunahuasi Program released to date

are discussed in news releases dated January 8, 2024, February 21, 2024, April 30, 2024, and May 9, 2024. The

assumptions and formula used to calculate copper equivalent for the Lunahuasi drill intersections noted above are

provided in the technical notes at the end of this news release.

A summary of the status of the drill holes of the 2023-2024 Lunahuasi Program as of the date of this new

release are as follows:

DPDH023 Hole completed; Results pending

Remaining assays from the final six holes of the 2023-2024 Lunahuasi Program will be released once received,

analyzed and confirmed by the Company.

Exploration potential at Lunahuasi is excellent, with mineralization remaining open in all directions, including

at depth, as noted most recently in hole DPDH018, which ended with the final 20.4 metres averaging 3.37%

CuEq (2.87% Cu, 0.45 g/t Au, and 20.2 g/t Ag). Both the vein and stockwork mineralization are interpreted to

be part of a porphyry copper-gold system, which the Company believes may be centered to the west of current

drilling at Lunahuasi. As the Company receives and analyzes the final assay results from the 2023-2024

Lunahuasi Program, it will update its geological interpretation of the deposit, which will form the basis for

developing its exploration strategy for a third Lunahuasi drill campaign to begin early in the fourth quarter of

2024.
