Val-d'or Mining Exploration Update

Perestroika Prospect - Eldorado Gold (Québec) Inc. Option Drill Results Including:

4.60 m @ 12.35 g/t Au from 269.40 m - PE-25-019

Including - 0.50 m @ 107.50 g/t Au from 270.00 m

Val-d'Or Mining Corporation (TSXV: VZZ) ("the Company") is pleased to announce on the results from the 2025 diamond drilling program on the Perestroika Prospect. The property is located in Courville Township, Québec, approximately 40 kilometres northeast of Val-d'Or, Québec. This property is under option to Eldorado Gold (Québec) Inc. who may earn a 70% interest in each of the Murdoch Creek, Claw Lake, Cook Lake and Perestroika properties, on the terms detailed below.

2025 Diamond Drill Program Outline and Objectives:

The 2025 diamond drilling program was budgeted at $0.84 M USD. Drilling activities were conducted over the February to March period with follow-up detailed logging, sampling and data compilation work as the holes were logged and analytical results received. A total of twelve (12) holes were completed (PE-25-009 to PE-25-020), for a cumulative sum of 5,004 metres drilled, utilizing two diamond drill rigs. Eldorado Gold is the project operator.

This is a Phase II diamond drilling program, intended to follow-up on promising gold values intercepted in the 2024 program. For specific details on the regional and property geology and the highlighted gold assay intersections from the 2024 drill program, including a drill hole location map and table of assay highlights, the reader is referred to the Val-d'Or Mining Corporation's December 19, 2024 news release.

The objectives of the 2025 drill program were as follows:

• To follow-up on DDH GPS-09-01 (3.05m @ 20.69 g/t Au) and PE-24-004 (8.60m @ 4.45 g/t Au (incl. 0.50m @ 18.16 g/t Au and 0.90m @ 12.33 g/t Au.);

• To define and delineate the existence of lithological and structural controls (i.e. plunge) on the previously intersected gold mineralized veins; and

• To test for additional shear zones and structures elsewhere the property.

Assays greater than 1g/t Au - See Table II - Assay Composites Intervals

The drilling results have expanded the mineralized footprint from the 2024 program to the southeast, northwest and south of GPS-09-01 and GPS-09-02, along strike and parallel to the mineralized trend.

Drillholes PE-25-14, PE-25-015, PE-25-019, and PE-25-020 followed up on the results of PE-24-008 (27.60 metres @ 0.53 g/t Au from 240.70 m), over approximately 350 metres (see above map). Wide zones of lower-grade mineralization were intersected, such as 18.40 m @ 1.28 g/t Au (145.60 m - 164.00 m) in PE-25-014, in addition to high-grade vein hosted mineralized zones such as 0.50 m @ 107.50 g/t Au from 270.00 m intersected in PE-25-019.

Immediately south of GPS-09-01 and GPS-09-02, PE-25-020 intersected 0.50 m @ 73.20 g/t Au from 38.10 m and 2.20 m @ 1.97 g/t Au from 56.5 m.

To the northwest along the mineralized corridor, PE-25-013 intersected 1.30 m @ 46.39 g/t Au from 29.70 m, located approximately 750 m northwest of GPS-09-01 and GPS-09-02.

These intersections do not represent true widths. The intersections highlighted in this press release represents drill indicated intersections along the core length.

The mineralization intersected is characterized as mostly being hosted in flat extensional quartz-ankerite veins and veinlets. Gold mineralization is closely associated with fine disseminated pyrite with sericite (white mica) alteration.

The mineralized corridor is located between two third order shear zones and is closely associated with a swarm of felsic tonalitic to intermediate dioritic dykes.

About Val-d'Or Mining Corporation

Val-d'Or Mining Corporation is a junior natural resource issuer involved in the process of acquiring and exploring its diverse mineral property assets, most of which are situated in the Abitibi Greenstone Belt of NE Ontario and NW Québec. To complement its current property interests, the Company regularly evaluates new opportunities for staking and/or acquisitions. Outside of its principal regional focus in the Abitibi Greenstone Belt, the Company holds several other properties in Northern Québec (Nunavik) covering different geological environments and commodities (Ni-Cu-PGE's).

The Company has expertise in the identification and generation of new projects, and in early-stage exploration. The mineral commodities of interest are broad, and range from gold, copper-zinc-silver, nickel-copper-PGE to industrial and energy minerals. After the initial value creation in the 100%-owned, or majority-owned properties, the Company seeks option/joint venture partners with technical expertise and financial capacity to conduct more advanced exploration projects.
