Val-D'Or Mining Exploration Update Perestroika Prospect Eldorado Option

Val-D'Or Mining Corporation (TSXV: VZZ,OTC:VDOMF) (OTCQB: VDOMF) ("the Company") is pleased to announce the commencement of an 8,000-metre diamond drilling program on the Perestroika Prospect. The property is in Courville Township, Québec, located approximately 40 kilometres northeast of Val-D'Or, Québec.

The Perestroika property is under option to Eldorado Gold (Québec) Inc. ("Eldorado") who may earn a 70% interest in each of the Murdoch Creek, Claw Lake, Cook Lake and Perestroika properties, on the terms detailed below.

2026 Diamond Drill Program Outline and Objectives:

The 2026 diamond drilling program is budgeted at $1.37 M USD. The program consists of 20 planned holes totalling approximately 8,000 metres, utilizing two diamond drill rigs. The number of holes will depend on the final depths and results obtained for each hole drilled.

This is a Phase III diamond drilling program, intended to follow-up on promising gold values from the 2024 and 2025 drill programs. For specific details on the regional/property geology, program objectives and the highlighted gold assay intersections from the 2024 and 2025 drill programs, including drill hole location maps and table of assay highlights, the reader is referred to the Val-D'Or Mining Corporation's December 19, 2024 (assays for holes PE-24-001 through to PE-24-008, GPS-09-01 EXT and GPS-09-02 EXT), and September 26, 2025 (assays for holes PE-25-10 and PE-25-012 through to PE-25-020) news releases.

The objectives of the drill program are as follows:

• Test the hypothesis that the quartz-ankerite gold bearing veins are stacked in an alignment parallel to the stretching lineation (steeply plunging northeast).

• Test for the presence of multiple shoots of high density stacked vein arrays.

• Follow-up drilling on the intercepts present in PE-24-005 (0.50m @ 213.08 g/t Au) and PE-25-013 (1.30m @ 46.36 g/t).

• Testing the lateral continuity of the quartz-ankerite vein system and determine the areas where the vein density is the highest.

• To test for possible parallel mineralized shear zones north and south of the identified dyke swarm corridor (highest density of the sub-parallel mineralized extensional quartz-carbonate-pyrite veins are concentrated primarily within an intermediate-felsic dyke swarm).

Eldorado is the project operator. Results from the current drill program will be reported on once received.

Summary of Results from the 2024-2025 drill programs:

• Most of the observed gold mineralized veins are flat and extensional.

• The felsic dyke and the gold mineralization are associated with pervasive sericitization.

• The highest density of extension quartz-ankerite veins are hosted in felsic intrusive dykes, within an estimated 150-200-metre wide shear zone corridor.

• Every single hole drilled in the 2025 program returned anomalous gold intervals.

• The best interval was intersected in PE-25-012: 16.30m @ 4.01 g/t Au, incl. 0.50m @ 66.30 g/t Au.

• 500 metres southeast, PE-25-019 returned 4.60m @ 12.35 g/t Au.

• A parallel gold bearing shear zone was identified in PE-25-013: 1.00m @ 46.36 g/t Au, extending the footprint of the mineralized corridor by 1,000 metres to the northwest.

• Based on the results from PE-25-013 (extreme northwest) and PE-25-019 (extreme southeast), the shear corridor is mineralized over its entire "investigated" strike length (1,500m) and is open along strike, and at depth.

• Potential discovery potential to find mineralized parallel structures, i.e. the shear intersected in PE-24-005, located approximately 250-300 metres south of the main shear corridor that returned an intersection of 0.50m @ 213.08 g/t Au.
