NGEx Minerals Ltd. Reports 2023 Results

Wojtek Wodzicki, President and CEO, commented, "The highlight of 2023 was the greenfield discovery of high-grade copper-gold-silver mineralization at Lunahuasi. An ongoing follow-up drill program continues to deliver outstanding copper-gold-silver intercepts, which continue to exceed our expectations, confirming Lunahuasi as one of the most exciting exploration projects in the world. We also made substantial progress at our Los Helados project during 2023. Drilling continued to extend the high-grade Fenix and Alicanto Zones discovered in 2022, and in December we published an updated Mineral Resource Estimate, which resulted in meaningful increases to tonnage, grades, and contained metals, further strengthening the largest current resource in the Vicuña District. Remarkably, both projects continue to hold significant exploration upside, particularly at Lunahuasi where drilling to date has not yet identified the boundaries of the high-grade vein system and has only tested a small portion of the overall alteration zone.

NGEx continues to strive to be a top-tier mineral exploration and development investment opportunity, and with a strong treasury balance, a portfolio of world-class exploration assets, a recent graduation to the Toronto Stock Exchange, and upgrade to the OTCQX® Best Market in the U.S., the Company is well positioned to carry its momentum through 2024 as it continues to generate value for its shareholders."

2023 and Subsequent Period Highlights

Lunahuasi High-Grade Discovery Made; Follow-up Program Underway

In May of 2023, NGEx successfully completed its first ever drill program at its 100%-owned Lunahuasi Project, located in San Juan, Argentina, which comprised a total of 4,912 metres ("m") of diamond drilling in eight holes (the "Maiden Lunahuasi Program"). The Maiden Lunahuasi Program was undertaken from January to May 2023, and intersected a series of quartz-sulphide veins carrying high values of copper, gold and silver, confirming a significant new discovery in the heart of the Vicuña District.

Highlights from the Maiden Lunahuasi Program include:

• DPDH002, which returned 60.0m at 7.52% copper equivalent ("CuEq") from 212.0m, comprised of 5.65% copper ("Cu"), 2.04 g/t gold ("Au"), and 44.0 g/t silver ("Ag"), and 10.0m at 7.08% CuEq from 574.0m, comprised of 3.70% Cu, 1.51 g/t Au, and 259.4 g/t Ag;
• DPDH005, which returned 33.4m at 3.50% CuEq from 636.0m, comprised of 2.50% Cu, 1.12 g/t Au, and 19.8 g/t Ag; and
• DPDH007, which returned 90.0m at 4.05% CuEq from 74.0m, comprised of 2.05% Cu, 2.46 g/t Au, and 23.2 g/t Ag, and 20.8m at 8.08% CuEq from 439.2m, comprised of 5.54% Cu, 2.02 g/t Au, and 121.3 g/t Ag.

A follow-up drill program began in October 2023 (the "2023-2024 Lunahuasi Program"), with an initial objective of approximately 15,000m of drilling. Drilling is expected to be completed in the second quarter of 2024. The primary objectives of the campaign are extending, and improving the Company's understanding of, the zone of high-grade mineralization. In addition, the Company plans to test new drill targets in and around the surrounding alteration zone.

To date, complete assay results for four holes have been received, analyzed and released by the Company, which have begun to illustrate the extent of the high-grade system. Highlights include:

• DPDH009, which returned 128.3m at 4.01% CuEq from 144.0 metres, comprised of 2.01% Cu, 2.07 g/t Au, and 57.0 g/t Ag, including:
  • 62.0m at 6.98% CuEq from 144.0 metres (3.75% Cu, 3.43 g/t Au, and 83.2 g/t Ag), which in itself included 26.1m at 13.36% CuEq from 168.9 metres (7.53% Cu, 5.83 g/t Au, and 178.6 g/t Ag);
• DPDH010, which returned 102.0m at 4.56% CuEq from 192.0m, comprised of 2.45% Cu, 1.71 g/t Au, and 97.3 g/t Ag, including:
  • 62.6m at 5.84% CuEq from 226.0 metres (3.10% Cu, 2.09 g/t Au, and 138.3 g/t Ag), which in itself included 9.4m at 12.10% CuEq from 232.0 metres (4.86% Cu, 4.49 g/t Au, and 450.2 g/t Ag); and
• DPDH014, which returned 184.2m at 4.61% CuEq from 166.0m, comprised of 2.85% Cu, 2.15 g/t Au, and 22.3 g/t Ag, including:
  • 71.9m at 9.63% CuEq from 171.2 metres (5.79% Cu, 4.70 g/t Au, and 46.9 g/t Ag), which in itself included 23.0m at 23.02% CuEq from 220.0 metres (14.68% Cu, 9.95 g/t Au, and 123.1 g/t Ag).

Drilling and assay results from the Maiden Lunahuasi Program and the 2023-2024 Lunahuasi Program, including those received and released since December 31, 2023, are discussed in news releases dated April 4, 2023, July 4, 2023, January 8, 2024, and February 21, 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.

Drilling at Lunahuasi continues with four rigs, and assays from the ongoing program will be released once received, analyzed and confirmed by the Company. 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:

Los Helados High-Grade Zones Continue to Expand; Mineral Resource Updated

In May 2023, the Company concluded its 2022-2023 field and drill campaign at its approximately 69%-owned Los Helados Project, located in Region III, Chile, which comprised 10,450m of diamond drilling in 11 holes (the "Los Helados Program"). The Los Helados Program successfully extended the high-grade Fenix and Alicanto Zones, which were discovered in 2022 and are distinct from, and in addition to, the Condor Zone, the high-grade breccia phase at the centre of the Los Helados deposit. Drilling and assay results from the Los Helados Program are discussed in news releases dated January 26, 2023, April 13, 2023, and July 18, 2023.

During the Los Helados Program, the Company also completed a comprehensive targeting exercise, which used detailed geophysical survey data and geological mapping to generate a number of new drill-ready targets with signatures similar to those associated with the Condor, Fenix, and Alicanto Zones. The Company continues to assess these exploration targets for future drill testing, however at this time, the Company has decided to focus its field personnel and resources on Lunahuasi.

In the fourth quarter of 2023, the Company completed an update to the Mineral Resource Estimate for Los Helados (the "2023 MRE"), which is detailed in the 43-101 technical report entitled "Technical Report on the Los Helados and Lunahuasi Projects, Chile and Argentina", dated December 13, 2023. The 2023 MRE has an effective date of October 31, 2023, and now has 2.1 billion tonnes of Indicated Resources at 0.51% CuEq, including 510 million tonnes grading 0.72% CuEq, representing a substantial higher-grade core above a 0.6% CuEq cut-off. In addition, the 2023 MRE also has over one billion tonnes of Inferred Resources grading 0.42% CuEq.

Compared to the previous Mineral Resource Estimate from 2019 (the "2019 MRE"), the 2023 MRE has made notable improvements to the overall tonnage, grades and contained metal for Los Helados as summarized in the following table:

Cautionary Note to U.S. Readers

Information concerning the mineral properties of the Company contained in this news release has been prepared in accordance with the requirements of Canadian securities laws, which differ in material respects from the requirements of securities laws of the United States applicable to U.S. companies subject to the reporting and disclosure requirements of the United States Securities and Exchange Commission (the "SEC").

Without limiting the foregoing, this news release uses the terms, such as "Indicated Resources" and "Inferred Resources". Investors in the United States are advised that, while such terms are defined in and required by Canadian securities laws, the SEC does not recognize them. Under United States standards, mineralization may not be classified as a reserve unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made. United States investors are cautioned not to assume that all or any part of Indicated or Inferred Resources will ever be converted into reserves as per United States standards. Furthermore, under Canadian rules, estimates of Inferred Resources may not form the basis of feasibility, pre-feasibility or other technical reports or studies, except in rare cases, as a result of the high amount of inherent uncertainty as to their existence and as to whether they can be mined legally or economically. Therefore, United States investors are also cautioned not to assume that all or any part of the Inferred Resources exist, or that they can be mined legally or economically. Disclosure of contained ounces is permitted disclosure under Canadian regulations; however, the SEC normally only permits issuers to report resources as in place tonnage and grade without reference to unit measures. Accordingly, information concerning descriptions of mineralization and Mineral Resource Estimates contained in this news release may not be comparable to information made public by United States companies subject to the reporting and disclosure requirements of the SEC.
