"San Antonio West continues to deliver some of the best near-mine exploration results we've seen at True North," stated Shaun Heinrichs, President and CEO. "These high-grade intercepts demonstrate the strength of the True North mineralized system and highlights the continued opportunity to outline new zones of mineralization adjacent to existing infrastructure. With the transition to underground drilling, we will accelerate resource growth across multiple target areas building towards a sustainable restart of operations."

1911 Gold has now completed seventy-five (75) surface drill holes, for a total of 20,398 m of drilling as part of the 2025 surface exploration drill program (the "2025 Surface Drill Program"). The 2025 Surface Drill Program focused on new targets defined by favourable host rocks and mineralized structural settings within the True North Mine footprint, also supported by significant historical drill intercepts that were close to surface and existing infrastructure. The most recent phase of the program consisted of two drill rigs targeting the down-dip extensions of mineralization at the new high-grade San Antonio Southeast ("SAM SE") and SAM W target areas, as well as the newly identified Shore target. The surface drilling program was completed on September 20, 2025, and these are the last assay results being reported for the program. Project activities have now shifted to underground exploration, resource expansion and resource delineation drilling. Underground drilling within the True North Mine commenced on October 1, 2025, with one (1) drill rig on Level 16 (695 m below surface) and a second drill rig added on November 6, 2025.

S an Antonio West Target: Discussion of Results

Drilling completed to date has confirmed the extensions of gold mineralization within the SAM gabbro to over 600 m northwest of the historically mined San Antonio zone, covering an area 400 m long and up to  630 m in depth. Twenty-six (26) surface drill holes, for a total of 6,087 m, were drilled on the SAM W target area as part of the 2025 program. The results of five (5) drill holes for 1,867 m are included in this press release, of which two (2) drill holes, TN-25-061 (311 m downhole depth) and TN-25-071A (30 m downhole depth), did not reach target depths and were abandoned due to hole deviation.

Drilling on the SAM W target confirmed the presence of a vein system parallel to the historical San Antonio ore body, which shares the same geology, alteration, and mineralization characteristics. The mineralized intercepts are characterized by quartz-carbonate shear veins and vein breccias with sericite, chlorite alteration and pyrite disseminated and in veinlets developed in association with east and northwest trending shear zone corridors.

Drill hole TN-25-064 tested the down-dip extensions of the modelled SAM W target area. Drilling successfully intercepted high-grade gold mineralization with the best intercept of 2.60 m @ 24.83 g/t Au (at 490.00 m downhole depth).

Drill hole TN-25-067 tested the 100 m down-dip extension of gold mineralization intersected in hole TN-25-058 (0.50 m @ 10.40 g/t Au), and intersected two distinct gold mineralized veins including 0.50 m @ 10.40 g/t Au, see press release dated June 10, 2025 (1911 Gold Intersects up to 58.66 g/t Au over 1.40 m on San Antonio West zone at True North).

Drill hole TN-25-71 was designed to test 100 m west of gold mineralization intersected in drill hole TN-25-060 (2.60 m @ 24.83 g/t Au), and intersected 0.80 m @ 12.80 g/t Au, see press release dated June 10, 2025 (1911 Gold Intersects up to 58.66 g/t Au over 1.40 m on San Antonio West zone at True North).  

Annex Target: Discussion of Results

Drilling completed on the Annex target defined high-grade gold mineralization within a dacitic volcaniclastic unit. The gold mineralization is associated with well-developed quartz shear veins and vein breccias within a carbonate, sericite +/- chlorite alteration assemblage and disseminated and veinlet-hosted pyrite and occasionally specs of native gold.

Drill hole TN-25-061 intercepted 0.50 m @ 10.00 g/t Au (at 247.30 m downhole depth) and 2.60 m @ 8.75 g/t Au (at 293.70 m downhole depth), including 1.00 m @ 18.00 g/t Au (at 295.30 m downhole depth).

Drill hole TN-25-064 intercepted 3.10 m @ 2.94 g/t Au (at 271.60 m downhole depth), including 1.00 m @ 6.71 g/t Au (at 273.70 m downhole depth).

Drill hole TN-25-067 intercepted 2.50 m @ 5.23 g/t Au (at 272.50 m downhole depth), including 2.00 m @ 5.76 g/t Au (at 273.70 m downhole depth), and 0.50 m @ 9.18 g/t Au (at 274.50 m downhole depth).

Drill hole TN-25-071 intercepted 1.40 m @ 6.73 g/t Au (at 307.60 m downhole depth), including 0.90 m @ 7.47 g/t Au.

The high-grade nature and width of the drill intercepts and the preliminary size of the area drilled (120 m on strike and 160 m vertically and open up and down dip) represent an additional emerging target within the mine footprint. Upon modelling, this area could be further drilled from surface to define a potential new ore source in close proximity of the True North Mine infrastructure.

San Antonio West Target

The SAM W target is located west of the historically mined San Antonio zone within the True North Mine. The SAM W target occurs within the gabbro of the San Antonio mafic unit and the intersection with the Cartwright South mineralized shear zone. The SAM gabbro hosts the majority of the known gold mineralization within the True North Mine and historically produced 1,309,351 ounces Au at an average grade of 9.33 g/t Au from San Antonio (see technical report entitled "NI 43-101 Technical Report on the True North Gold Project, Bissett, Manitoba, Canada, dated December 23. 2024). 

Annex  Target

The Annex target is located 300 m east of the Cartwright Zone and 1 kilometre ("km") northwest of the Hinge deposit, and was first intersected in a 2012 and 2013 surface exploration drilling program. The target is located at the intersection of the Cartwright South shear zone with a dacitic volcanoclastic unit, potentially the northwest extension of the host unit of the Hinge deposit, and covers an area with a 120 m east-west strike length by 160 m vertically, and is open both along strike and at depth. Additional interpretation is ongoing to model the extent of the mineralized zone to assess up-side potential.

Next Steps

With the latest phase of surface drilling within the mine lease completed in late September, the Company has shifted its focus to an expanded underground drill campaign within the True North Mine footprint. Two (2) underground drill rigs are currently active on Level 16, an area that provides multiple favourable drill stations and immediate access to high-priority targets. Underground drilling is designed to continue testing the down-dip extensions of the SAM W,  SAM SE and Shore discoveries, as well as evaluating several newly defined exploration targets (see press release dated September 25, 2025). The program will also include delineation drilling of two test mining areas accessible from Level 16 and  drill testing the extensions of the current resource.

Rehabilitation work will also commence in two key areas over the coming months: the L13 deposit area, accessed by a ramp from the Hinge decline, and Level 6, a previously unsurveyed level located 262 m below surface, extending northwest from the A Shaft of the historical San Antonio workings. The L13 area will provide improved access to drill the down-dip extensions of the SAM SE target, while rehabilitation on Level 6 will support continued drilling of the SAM W target and potential drilling of the Cartwright Zone to the west, an area hosting a mineral resource open-at-depth. Additional surface drilling is currently being planned to continue testing the SAM W and Shore targets over the winter.

Concurrently, the Company is advancing permitting for a 2,200 m surface drill program at Ogama-Rockland, a near-surface target with a high-grade NI 43-101 mineral resource, located 35 km southeast of the True North complex (see Technical Report dated November 15, 2013, "A Technical Review of the Ogama-Rockland Deposit on the Rice Lake Property, Manitoba, Canada," prepared by Watts, Griffis and McOuat). The Company expects to receive approval to commence drilling in the coming weeks, which would allow the program to begin before year-end.
