Val-D'Or, Québec--(Newsfile Corp. - October 26, 2026) - Val-D'Or Mining Corporation (TSXV: VZZ) (OTCQB: VDOMF) ("the Company") is pleased to report on the receipt of additional analytical results from the winter 2026 diamond drilling program on the Perestroika Prospect. The property is in Courville Township, Québec, located approximately 40 kilometres northeast of Val-D'Or, Québec.

2026 Diamond Drill Program Update:

The 2026 diamond drilling program included 20 planned diamond drill holes totalling approximately 8,000 metres, utilizing two diamond drill rigs. Drilling activities were completed on April 6^th and equipment demobilized from the property on April 9^th. A total of twenty-five (25) NQ diamond drillholes were completed (PE-26-021 to PE-26-45), for a cumulative 12,477 metres drilled.

The current mineralized footprint on the property shows a mineralized corridor 1,000 metres along strike by 150 metres wide, between two shear corridors. Drilling in 2026 was conducted over 1,200 metres along the northwest-southeast tending mineralized deformation corridor, testing for its strike extensions.

Table I: Diamond Drillhole Information

Note: PE-26-039A was abandoned due to hole deviation - unintended changes in azimuth (horizontal direction) and dip (inclination/vertical angle), azimuth; and PE-26-45 and PE-26-45A abandoned due to casing movement.

Map I: Diamond Drill Hole Plan

For comparative purposes, the 2025 diamond drill program consisted of twelve (12) NQ holes completed for a cumulative 5,004 metres drilled. In 2024, the diamond drill program consisted of eight (8) NQ holes drilled and extended two (2) previous holes (GPS-09-01 and GPS-09-02 - the Golden Valley Mines discovery holes) for a cumulative 4,470 metres drilled. The total metres drilled over the 3-year period from 2024 to 2026 is 21,951 metres in 45 drillholes, plus 2 drillhole extensions.

Eldorado Gold is the project operator. Core logging of the drillholes has been completed, and the initial analytical results received. Currently as of the results reported in this news release, 4,458 sample results remain pending from the laboratory.

For details of the 2026 Diamond Drill Program Outline and Objectives, the reader is referred to Val-D'Or Mining Corporation's February 19, 2026; March 30, 2026; May 5, 2026; and August 5, 2026 news releases.

Several additional gold-mineralized intersections have been recorded from additional analytical results issued by the project operator Eldorado Gold (Québec). These intersections from drillholes PE-26-033; PE-26-034; PE-26-039; PE-26-039A; and PE-26-40, consist of multiple intervals of altered felsic dyke sections, hosting mineralized extensional and flat-lying (stacked) quartz-ankerite veins. Preliminary indications from the core logging suggest that the gold content is usually proportionate with sulphide content, that being pyrite, and local occurrences of visible gold.

Glenn Mullan (President/CEO) of Val-D'Or Mining stated that "The objective of these five (5) drillholes was to test the idea that the flat extensional gold-bearing quartz-ankerite veins are stacked in an alignment parallel to the stretching lineation, and to test for the presence of multiple shoots of high-density stacked veins. These additional results are highly encouraging, spanning a lateral strike length of over 1,100-metres intermittently along the southern portion of the presently defined, 1,200-metre NW-SE mineralized footprint, located between two shear corridors separated by 150-metres."

These five (5) drillholes are summarized below:

DDH PE-26-039 & DDH PE-26-039A: Target/Objective - Drilled down plunge to test the theory that the gold bearing quartz-ankerite veins are stacked in an alignment parallel to the stretching lineation and test for the presence of multiple shoots of high density stacked veins. Drilled at a high-angle, intersected very high density of felsic dykes injected with quartz-ankerite veins in the first 200 metres of coring.

PE-26-039: The hole was stopped at a depth of 42 metres and restarted with PE-26-039A. The hole intersected 12.00 m @ 1.93 g/t Au (21.60 m to 33.60 m), including 2.40 m @ 7.67 g/t Au (21.60 m to 24.00 m). This intersection includes 0.50 m @ 28.51 g/t Au (21.60 m to 22.10 m) and is associated with a quartz-ankerite vein, containing pyrite, injected in felsic dyke and in the strongly sericitized and silicified basalt located at the lower contact of the dyke.

PE-26-039A: Intersected 25 intervals with gold assays greater than 1g/t. The best interval intersected was 4.30 m @ 2.86 g/t Au (31.80 m to 36.10 m), including 0.80 m @ 11.07 g/t Au. This zone is associated with quartz-ankerite veins injected into strongly sericitized and silicified basalt.

Two large weakly mineralized zones (14.00 m and 15.50m) returned respectively: 0.71 g/t Au (87.00 m to 101.00 m), including 0.50m @ 5.45 g/t Au (89.00 m to 89.50 m) and 0.56 g/t Au (105.00 m to 120.50 m), including 0.50m @ 2.45 g/t Au (116.00 m to 116.50 m) and 0.30 m @ 3.85 g/t Au (120.20 m to 120.50 m). Both intervals are associated with quartz-ankerite vein swarms injected into a felsic dyke unit. Between 230.00 m and 230.50 m a mineralized quartz-ankerite vein injected in a felsic dyke, returned 0.50 m @ 13.58 g/t Au.

Additional mineralized intersections downhole included, 0.50 m @ 2.28 g/t Au (262.50 m to 263.00 m) in association with quartz-ankerite veins injected in a felsic dyke, and 1.00 m @ 2.05 g/t Au (371.00 m to 372.00 m) associated with quartz-ankerite veins injected in ankeritized basalt.

PE-26-040: The hole intersected several intervals grading greater than 1 g/t Au. Some of the better recorded zones intersected, included 0.50 m @ 5.69 g/t Au (232.30 m to 232.80 m) and this interval is associated with a quartz-ankerite vein injected in a felsic dyke. A 10.0 metre thick anomalous interval returning 0.70 g/t Au (259.3 m to 269.3 m), including 0.70 m @ 5.26 g/t Au (268.10 m to 268.80 m). This intersection is associated with quartz-ankerite veins injected in a felsic dyke. Further down the hole, additional mineralized zones were intersected, including 0.50 m @ 5.09 g/t Au (284.00 m to 284.50 m); 0.65 m @ 7.70 g/t Au (318.80 m to 319.45 m), 0.60 m @ 4.03 g/t Au (323.70 m to 324.30 m), 0.70 m @ 6.25 g/t Au (335.45 m to 336.15 m); 2.10 m @ 2.19 g/t Au, including 0.50 m @ 4.08 g/t Au (390.00 m to 390.50 m), and 0.50 m @ 5.19 g/t Au (546.80 m to 547.30 m)

Based on these results, PE-26-040 extended the mineralization at depth and along strike northwest of the main mineralized area.

Property Exploration Summary and Highlights:

The Perestroika Prospect lies along a structural corridor of intense deformation and alteration within the WNW-ESE trending Uniacke Deformation Corridor, inferred as the southeastern strike extension of the prolific Destor-Porcupine Deformation Zone. Previous exploration work located on the Perestroika Prospect established the presence of a gold mineralized trend hosting two (2) historical surface showings, referred to as the "Uniacke Shear" and "Glasnost" gold occurrences. In 2009, drilling by Golden Valley Mines and Royalties Ltd. successfully intersected multiple zones of high-grade gold mineralization associated with these historical gold showings, including drill intersections of 1.15 metres averaging 59.52 g/t Au, including 0.30 metres grading 217 g/t Au in GPS09-01 and 3.50 metres averaging 18.08 g/t Au, including 3.05 metres averaging 20.69 g/t Au in GPS09-02 (GM 54860).

This Phase III diamond drilling program, intended to follow-up on promising gold values from the 2009 Golden Valley Mines and Royalties Ltd. drill program results and the subsequent Eldorado operated drill programs in 2024 and 2025. 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 following three maps illustrate the 2024, 2025 and 2026 drilling highlights currently reported on the Perestroika Prospect.

Sampling, Analytical Methods and QA/QC Protocols:

Holes PE-26-021 to PE-26-025 were assayed at ALS Canada Ltd. Holes PE-26-026 to PE-26-030 were assayed at Bourlamaque Assay Laboratories Ltd. with sample preparation and gold analysis completed in Val-d'Or, Québec. Gold values were determined by 30g Py-SAA finish with over limits (>10g/t Au) by a 30g GRAV finish. Note that ICP data is pending and was sent to ALS Canada Ltd. for 48 Element Four-Acid ICP-MS code ME-MS61. Eldorado Gold (Quebec) QAQC procedure is Blanks every 20 samples and Standards alternating every 20 samples as well. Two Duplicate samples are taken at every 100 samples. All of this varies depending on the presence of visible gold with the Blanks and Standards placed before the sample containing the visible gold. Chain of custody for the majority of samples was handled entirely by Eldorado with respect to cutting, bagging and shipping samples to ALS Canada Ltd. and Bourlamaque Assay Laboratories. A portion of the samples were handled by the Groupe Axenix per diamond saw cutting, bagging and analytical shipment.
