Shaun Heinrichs, President and CEO, stated, “We are pleased with the ongoing positive results from the infill and delineation drill program at True North. This program is providing strong support for a potential mine restart decision in 2027. The infill drilling at L10 continues to derisk our mineral resources in this zone, which is readily accessible from Level 16, where we are currently advancing underground development to access zones for test mining and bulk sampling in 2026 and 2027.

“We expect the results from the L10 infill drilling to support upgrading the resources in preparation for an updated mine plan and delineation drilling. In addition to supporting the planned mineral resource update, the drill program has also intersected mineralization outside the current resource, potentially extending the modelled veins at L10.”

The underground Infill Drill Program, which commenced on October 1, 2025, has focused on upgrading and delineating the resources in areas scheduled for the early years of production in the PEA mine plan and on supporting the planning and execution of development currently underway for test mining activities.

The Company has commenced work on an updated global resource estimate, which will include True North exploration drilling (from surface and underground) as well as the Infill Drill Program. The updated estimate is currently scheduled for completion in the fourth quarter of 2026.

Table 1: Select Significant Drill Results – True North Underground Infill Drill Program (L10 Zone)

The L10 Zone is located at the intersection of the Shoreline Basalt unit and the regional east-west steeply north-dipping L10 Shear Zone, with gold-bearing mineralization associated with veins developed as generally northwest-trending extensional stockwork and breccia veins and east-west steeply north-dipping shear veins. Veining is predominantly composed of quartz with accessory ankerite and albite, with sericite-pyrite and chlorite as veinlets and pervasive alteration halos. Gold is associated with minor pyrite and as free native gold.

The underground infill drilling reported on today was designed to test the continuity of gold mineralization, confirm vein geometry, and assess grade distribution of the V-1020 and V-1010 veins within the L10 Zone, and to upgrade the inferred resources to indicated resources in areas outlined for development and mining in the early years of the PEA mine plan. Drilling was planned on a nominal 30 m drill hole spacing. Results reported are from thirty (30) drill holes totaling 6,483 m, with all drill holes intercepting the modelled veins and all holes returning significant results except hole UG16-26-101. Preliminary overall results are in line with expectations on the V-1020 Vein and lower than expected on the V-1010 Vein.

A number of infill drill holes also intercepted mineralization outside of the currently modelled vein wireframes supporting the 2024 MRE, which are not included in the PEA mine plan.

L10 (V-1020 Vein) Infill Drilling: Discussion of Results:

A total of eleven drill holes for 2,406.0 m of drilling was completed on the V-1020 Vein, with preliminary reviews concluding that the general gold distribution aligns with the expected average grade, with significant results encountered in UG16-26-091, which intersected 18.70 g/t Au over 0.60 m (at 179.80 m downhole depth), UG16-26-093, which intersected 13.98 g/t Au over 1.20 m (at 192.80 m downhole depth), and UG16-26-099, which intersected 13.84 g/t Au over 1.70 m (at 181.30 m downhole depth).

Three (3) of the infill drill holes also intersected gold mineralization outside of the 2024 MRE boundary, potentially extending gold mineralization at depth. Drill hole UG16-26-095 intersected 18.10 g/t Au over 0.80 m (at 224.50 m downhole depth); UG16-26-098 intersected 3.69 g/t Au over 2.20 m (at 161.20 m downhole depth); and UG16-26-106 intersected 5.56 g/t Au over 0.50 m (at 181.90 m downhole depth).

L10 (V-1010 Vein) Infill Drilling: Discussion of Results:

A total of nineteen drill holes for 4,077.0 m of drilling was completed on the V-1010 Vein, with average vein thickness in line with expectations within the modelled veins.

Preliminary overall results are slightly lower than expected, with some pinch-and-swell geometry observed, requiring tighter drill spacing to properly delineate the targeted vein. Wider, higher-grade zones were intersected, including in drill hole UG16-26-102, which returned broad mineralization of 14.86 g/t Au over 7.20 m (at 202.40 m downhole depth), including 19.52 g/t Au over 4.60 m, including 31.70 g/t Au over 0.60 m.

Eleven resource infill drill holes also intersected significant gold mineralization on the down-plunge extension of the V-1020 and V-1011 veins at L10, located in the hanging wall of the V-1010 Vein and outside of the 2024 MRE boundary, potentially extending the resources hosted in these zones to depth.

Drill hole UG16-26-081 intersected 4.84 g/t Au over 1.30 m (at 125.70 m downhole depth), UG16-26-083 intersected 22.64 g/t Au over 2.10 m (at 124.00 m downhole depth), UG16-26-089 intersected 25.50 g/t Au over 0.70 m (at 115.00 m downhole depth), UG16-26-105 intersected 8.70 g/t Au over 1.90 m (at 148.10 m downhole depth), UG16-26-107 intersected 14.30 g/t Au over 0.60 m (at 207.00 m downhole depth), and UG16-26-111 intersected 6.04 g/t Au over 2.70 m (at 195.90 m downhole depth). Mineralization was extended by up to 75 m below the 2024 MRE boundary down-plunge on the V-1020 Vein, and by up to 70 m down-plunge on the V-1011 Vein.

1911 Gold has commenced a mineral resource update for True North expected in Q4/2026, which will include the new discoveries and resource expansion of known zones, along with results from the initial phase of the Infill Drill Program.

Exploration drilling at True North, from surface and underground, will recommence upon review of the recently completed drill program and resource update.

The Company’s ongoing Infill Drill Program on areas contemplated for test mining and the early years of the PEA mine plan is being conducted from underground with three drill rigs: two on Level 16 and one from the Hinge decline.
