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 6thand equipment demobilized from the property on April 9th. 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.

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:

Selective Individual Diamond Drillhole Assay Intersection Highlights

PE-26-33: Target/Objective - Drilled as a "reverse-strike" hole and to verify if multiple shoots of quartz-ankerite veins are present in the felsic dykes in the shear corridor.

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.

PE-26-039: 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). The interval 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 also in the strongly sericitized and silicified basalt located below the dyke. The 0.70 m @ 2.04 g/t Au (30.40 m - 31.10 m) intersection is associated with a quartz-ankerite-tourmaline extension vein.
