1911 Gold Confirms Resource Continuity in Underground Infill and Delineation Drilling at True North
Press Release
Vancouver, British Columbia, March 11, 2026 – 1911 Gold Corporation (“1911 Gold” or the “Company”) (TSXV: AUMB; OTCQX: AUMBF; FRA: 2KY) is pleased to provide 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 twenty-five (25) drill holes for 3,894 metres (“m”) from the infill and delineation drill program on the mineral resources outlined within the mine plan in the recent 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 have confirmed the continuity of gold (“Au”) mineralization within the mineral resources outlined in the PEA mine plan for the early years of mining on the V-810 vein within the Hinge Zone (“Hinge”), and the V-1030/V-1040 vein within the L10 Zone (“L10”), both located adjacent to Level 16 (695 metres below surface) of the True North mine.
- Hinge Infill and Delineation Drill Program – drilling confirmed continuity of the targeted V-810 vein and returned wider widths on average than the modelled vein, with the following highlighted results:
- UG16-25-006: Intersected 10.03 grams per tonne (“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
- UG16-25-015: Intersected 10.79 g/t Au over 2.20 m (at 119.70 m downhole depth), including 12.91 g/t Au over 1.70 m, including 14.60 g/t Au over 1.10 m
- UG16-25-017: Intersected 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
- UG16-25-027: Intersected 5.23 g/t Au over 2.00 m (at 118.70 m downhole depth)
- UG16-25-028: Intersected 4.75 g/t Au over 2.90 m (at 131.80 m downhole depth), including 10.60 g/t Au over 0.60 m
- UG16-26-031: Intersected 5.02 g/t Au over 6.00 m (at 108.70 m downhole depth), including 11.45 g/t Au over 1.70 m, including 15.90 g/t au over 0.80 m
- UG16-26-034: Intersected 6.65 g/t Au over 2.20 m (at 121.90 m downhole depth), including 9.72 g/t Au over 0.60 m, and 7.88 g/t Au over 0.80 m
- UG16-26-035: Intersected 3.83 g/t Au over 2.90 m (at 123.30 m downhole depth), including 9.59 g/t Au over 0.90 m
- L10 Infill Drill Program – drilling confirmed the continuity of V-1040, with the following highlighted result:
- UG16-25-009: Intersected 4.38 g/t Au over 1.00 m (at 162.20 m downhole depth)
Shaun Heinrichs, President and CEO stated, “We are pleased to provide the first set of drill results from our underground infill and delineation drill program as we systematically de-risk True North for a production restart next year. The drilling at Hinge and L10 not only confirms the continuity of gold mineralization in these veins but also demonstrates that these zones are wider on average than previously modelled. 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 plan and support the bulk sample and test mining activities scheduled for later this year. We look forward to providing additional results as we continue to advance underground activities at True North.”
The underground infill and delineation drill program commenced on Level 16 with one (1) drill rig on October 1, 2025, with a second drill rig added on November 6, 2025. Initial drilling 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.
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 have also been mobilized to test the near-surface extensions of gold mineralization previously intersected at San Antonio West, SAM SE and Shore targets. Drilling is ongoing, and additional results will be released as they become available.

Hinge (V-810) Infill and Delineation Drilling
Underground infill and delineation drilling was designed to test the continuity of gold mineralization of the V-810 vein located within the Hinge Zone as outlined for development and mining in the early years of the PEA mine plan. Results reported today are from twenty-one (21) drill holes totaling 3,143 m. Drill targets were set up on nominal 15 m drill hole spacing to upgrade indicated resources to the measured resource category.
Assay results returned the following highlights and preliminary definition of an approximate 120 m long and 100 m wide zone plunging N13E/52° hosted within the Hinge Dacitic breccia unit and the intersection of the regional mineralized Hinge shear zone. All mineralized intercepts are characterized by quartz-carbonate shear veins and vein breccias with sericite, chlorite alteration and pyrite disseminated and in veinlets. 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. Drill holes intercepted the modelled vein structure within the targeted V-810 vein over wider widths on average than the current modelled vein and defined a ~40 m wide higher grade gold core with the following highlighted results.
Drill hole UG16-25-006 intercepted 10.03 g/t over 1.10 m (at 136.80 m downhole depth), including 14.50 g/t Au over 0.50 m; UG16-25-010 intersected 9.87 g/t over 1.60 m Au (at 149.40 m downhole depth); UG16-25-015 intercepted 10.79 g/t Au over 2.20 m (at 119.70 m downhole depth), including 14.60 g/t Au over 1.10 m over 0.70 m; UG16-25-017 intercepted 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; UG16-25-027 intercepted 5.23 g/t Au over 2.00 m (at 118.70 m downhole depth); UG16-25-028 intercepted 4.75 g/t Au over 2.90 m (at 131.80 m downhole depth), including 10.60 g/t Au over 0.60 m; UG16-25-031 intercepted 5.02 g/t Au over 6.00 m (at 108.70 m downhole depth), including 15.90 g/t Au over 0.80 m; UG16-25-034 intercepted 6.65 g/t Au over 2.20 m (at 121.90 m downhole depth), including 9.72 g/t Au over 0.60 m; and drill hole UG16-25-035 intercepted 3.83 g/t Au over 2.90 m (at 123.30 m downhole depth), including 9.59 g/t Au over 0.90 m.
Additional infill and delineation drill holes from Hinge will be released upon receipt of final assay results.
L-10 (V-1030/V-1040) Infill Drilling
A total of four (4) drill holes for 750 m of drilling was completed as infill drilling on areas with wider drill spacing on L10, also located on Level 16, as outlined for development and mining in the early years of the PEA mine plan. One (1) drill hole (UG16-25-009) deviated and did not intersect the targeted area and was replaced by drill hole UG16-25-014.
L10 is hosted within the Shoreline Basalt unit on the intersection with the regional mineralized L10 shear zone and is characterized by gold mineralized quartz-carbonate shear veins and vein breccias with sericite, chlorite alteration and pyrite disseminated and in veinlets, with highlighted results below.
The continuity of the V-1040/V-1030 veins was confirmed with drill holes UG16-25-008 which intercepted 2.31 g/t Au over 1.30 m (at 133.70 m downhole depth); UG16-25-012 intercepted 2.60 g/t Au over 0.90 m (at 163.10 m downhole depth).
Drill hole UG16-25-009 deviated and did not intersect the targeted area but intercepted possible extensions of L10 returning 4.38 g/t Au over 1.00 m (at 162.20 m downhole depth, potential extension of vein V-1040) and 4.35 g/t Au over 1.50 m (at 198.10 m downhole depth, potential down plunge extension of vein V-1030).

- 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. Final results from additional holes intersecting potential new veins at Hinge are pending.
Preliminary interpretation indicates a vein system parallel to the Hinge vein V-810, and the L10 veins V-1030/V-1040, which occur 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).
