1911 Gold Reports Additional Results from Underground Delineation Drilling at True North

Press Release

Vancouver, British Columbia, April 2, 2026 – 1911 Gold Corporation (“1911 Gold” or the “Company”) (TSXV: AUMB; OTCQX: AUMBF; FRA: 2KY) is pleased to provide additional assay results from the underground drill program at the Company’s wholly-owned operational and fully permitted True North Gold Project (“True North”), located in southeast Manitoba, Canada.

These assay results represent ten (10) drill holes for 1,464 metres (“m”) from the underground delineation drill program on the mineral resources outlined within the mine plan in the recent True North Preliminary Economic Assessment (“PEA”), in preparation for development and mining activities (see press release dated February 10, 2026, “1911 Gold Delivers Positive PEA for True North Highlighting Robust Economics with Low Capital Intensity and High Returns”).

Drilling Highlights:

• Drilling results confirmed continuity of gold (“Au”) mineralization within the Hinge Zone (“Hinge”) V-810 vein as outlined in the PEA mine plan for the early years of mining, located adjacent to Level 16 (695 metres below surface).
• Hinge Delineation Drill Program – the latest drill results reported complete this program for Hinge, with the following highlighted results:
• UG16-26-038: Intersected 9.51 grams per tonne (“g/t”) Au over 3.50 m (at 133.80 m downhole depth), including 12.70 g/t Au over 0.70 m, and 30.70 g/t Au over 0.60 m
• UG16-26-046: Intersected 12.00 g/t Au over 1.00 m (at 128.80 m downhole depth), and 7.44 g/t Au over 0.50 m (at 132.00 m downhole depth)
• UG16-26-041: Intersected 6.71 g/t Au over 2.00 m (at 117.00 m downhole depth), including 11.40 g/t Au over 0.80 m
• UG16-26-042: Intersected 5.78 g/t Au over 1.10 m (at 118.00 m downhole depth), including 6.46 g/t Au over 0.50 m
• UG16-26-043: intersected 4.10 g/t Au over 1.40 m (at 112.90 m downhole depth), including 5.59 g/t Au over 0.70 m
• Additional drilling is planned to test the extension of the V-810 vein at Hinge between the current resource and Level 16, located 25m down plunge

Shaun Heinrichs, President and CEO stated, “Drilling has confirmed mineralization within the targeted V-810 vein within Hinge, an area that will be considered for test mining activities later in the year. These additional results are in line with previous delineation drilling at Hinge with a consistent core of higher-grade gold mineralization approximately 40 m wide extending approximately 100 m down plunge. The ongoing drill program is focussed on infill and delineation drilling in areas that are included in the first years of mining within the PEA mine, as well as exploration and resource expansion drilling. We currently have two drills on surface and plan to mobilize a third underground drill rig over the next month which will continue to provide infill and resource expansion results as we expand our resource base in 2026 and advance towards the planned mine restart in 2027.”

The underground infill and delineation drill program has focused on two areas scheduled for early production in the PEA mine plan that are readily accessible from the existing Level 16 development. Current development drilling continues to focus on upgrading and delineating the resources for the initial years of the mine schedule and supporting the upcoming bulk sampling and test mining activities. The latest results reported conclude the current delineation drill program on the Hinge V-810 vein, with thirty-one (31) drill holes completed to date for a total of 4,608 m. Results from the delineation drilling on Hinge V-810 will be incorporated into the project database to improve the vein wireframe modelling and to update the resources and stope designs to support an optimized mine plan.

Exploration Drilling

Beyond the immediate mine plan, 1911 Gold has been testing new target areas within the True North mine footprint. This includes underground drilling on the new Shore target and the San Antonio Southeast (“SAM SE”) depth extensions, as well as testing the extensions of mineral resources included in the PEA mine plan. Additional underground drill results on the potential new resource targets and resource expansion areas will be released upon receipt of final assay results.

Two (2) surface drill rigs were mobilized in early February to test the near-surface extensions of gold mineralization previously intersected at the San Antonio West, SAM SE and Shore targets. Drilling is progressing on all targets, and additional results will be released as they become available.

Discussion of Results – Hinge (V-810) Infill and Delineation Drilling

The latest Hinge Zone (V-810) delineation drill results from the last ten (10) drill holes totaling 1,464 m confirmed the continuity of gold mineralization within proposed stopes outlined in the recent PEA mine plan. Drill holes were planned to intersect the modelled vein on a nominal 15 m spacing to upgrade indicated resources to the measured resource category. The V-810 vein modelled in this zone had an average width of 1.2 m, diluted to 1.5 m minimum width in the PEA mine plan

The V-810 vein is hosted by a dacitic lapilli tuff unit, characterized by northwest trending shear and extensional stockwork style veins and vein breccias subparallel to the stratigraphy and are predominantly comprised of white quartz with accessory Fe-carbonate and albite, containing thin bands of tourmaline- sericite-pyrite and chlorite. Gold is associated with pyrite, with free native gold also occurring. Geological interpretation and assay results for holes highlighted in this release support the definition of an approximate 120 m long and 100 m wide zone plunging N13E/52° hosted within the dacitic lapilli tuffs unit and the intersection of the regional mineralized Hinge shear zone.

Eight (8) of the ten (10) drill holes completed intercepted the vein, with overall average widths as expected including UG16-25-041 which intersected 6.71 g/t Au over 2.00 m (at 117.00 m downhole depth), including 11.40 g/t Au over 0.80 m; UG16-25-042 which intersected 5.78 g/t Au over 1.10 m (at 118.00 m downhole depth; and UG16-25-046 which intersected 12.00 g/t Au over 1.00 m (at 128.80 m downhole depth), and 7.44 g/t Au over 0.50 (at 132.00 m downhole depth). Data interpretation defines a classic “pinch-and-swell” geometry of shear hosted veins both on strike and vertically with a consistent core of higher-grade gold mineralization approximately 40 m wide extending approximately 100 m down plunge (see press release dated March 11, 2026, “1911 Gold Confirms Resource Continuity in Underground Infill and Delineation Drilling at True North”) which returned results including 10.03 g/t over 1.10 m Au (at 136.80 m downhole depth), including 14.50 g/t Au over 0.50 m in hole UG16-25-006; 10.79 g/t Au over 2.20 m (at 119.70 m downhole depth) in hole UG16-25-015, including 14.60 g/t Au over 1.10 m; 6.62 g/t Au over 3.40 m (at 135.60 m downhole depth), including 23.60 g/t Au over 0.70 m in hole UG16-25-017.

Vein wireframe update and assay results from the delineation program will support for the update resource estimate and the mine plan optimization for this area.

Additional drilling is planned to test the potential extensions of the Hinge V-810 vein above Level 16, which is located 25m down plunge.

3. Intervals represent drill core length and are considered to represent 60% to 90% of true widths
4. Drill hole Information included in Table 3
5. Newly intercepted veins not in the current resource model or PEA mine plan

A number of drill holes also intercepted mineralization outside of the currently modelled veins and which are not included in the PEA mine plan. Preliminary interpretation indicates a potential vein system parallel to the Hinge vein V-810, which occurs outside of the modeled wireframes supporting the 2024 mineral resource estimate and will be further interpreted and modelled to define potential resource additions (see technical report entitled “NI 43-101 Technical Report on the True North Gold Project, Bissett, Manitoba, Canada”, prepared by Lions Gate Geological Consulting Inc. and 1911 Gold, dated December 23, 2024). Further interpretation is ongoing to define potential mineralization continuity to support vein wireframe modelling.

The Company also wishes to clarify disclosure in its news release dated March 11, 2026. An interval disclosed in the “Drilling Highlights” on the first page, previously reported for drill hole UG16-25-006 as 10.03 g/t Au over 1.10 m (at 136.80 m downhole depth), including 12.91 g/t Au over 1.70 m, including 14.50 g/t Au over 0.50 m, should have been disclosed as 10.03 g/t Au over 1.10 m (at 136.80 m downhole depth), including 14.50 g/t Au over 0.50 m (where the information is reported correctly in Table 1 of the release). This correction does not materially impact the interpretation of the drill results.
