1911 Gold Intersects 12.69 g/t Au over 2.40 m on SAM Southeast and
Discovers New Zone at True North Gold Project
Vancouver, British Columbia , October 7, 2025 – 1911 Gold Corporation ("1911 Gold " or the
"Company") (TSXV: AUMB; OTCQB: AUMBF; FRA: 2KY) is pleased to announce new assay results from
the surface drill program at the Company’s wholly-owned operational and fully permitted True North Gold
Project, centrally located within the Company’s 100%-owned Rice Lake Gold property, southeast Manitoba,
Canada. The latest assay results are from eight ( 8) drill holes for 3,557 m etres (“m”) targeting the San
Antonio Southeast target (“SAM SE”) and the newly identified Shore target.
Drilling* Highlights:
• Drilling completed to date on the new SAM SE target confirms the down-dip extensions of quartz
vein-hosted gold (‘Au”) mineralization by 745 m and identifies a new mineralized target, Shore,
located adjacent to SAM SE and centered on the intersection of the SAM gabbro and the 007
shear
• TN-25-065: Intersected 28.60 grams per tonne (“g/t”) Au over 0.50 m; 12.69 g/t Au over 2.40 m,
including 15.20 g/t Au over 0.70 m and 24.90 g/t Au over 0.70 m
• TN-25-062: Intersected 7.05 g/t Au over 0.50 m; 6.21 g/t Au over 0.50 m; 7.03 g/t Au over 3.20 m,
including 20.10 g/t Au over 0.50 m and 18.60 g/t Au over 0.50 m; 7.38 g/t Au over 1.10 m, including
11.40 g/t Au over 0.60 m
• TN-25-063: Intersected 19.40 g/t Au over 1.40 m, 5.46 g/t Au over 1.00 m, 4.37 g/t Au over 1.20 m,
and 6.74 g/t Au over 0.60 m
• TN-25-070: Intersected 33.80 g/t Au over 0.80 m at Shore
• The results for an additional five (5) surface holes for 1,867.0 m of drilling on the San Antonio
West (“SAM West”) target are pending
* All drill results are quoted as downhole drill lengths.
“Our surface drill program at San Antonio Southeast and San Antonio West continues to demonstrate the
size potential of these targets to add to the mineral resource base and potentially expand our future mining
operations,” stated Shaun Heinrichs, President & CEO. “Developing new zones close to surface and current
infrastructure provides potential operational efficiencies and expansion possibilities. We also see exciting
potential at the new Shore target, our third new discovery, located south of San Antonio Southeast, which
we plan to test further in the ongoing exploration drill program. We are very encouraged by the exploration
drill results received to date and look forward to advancing our underground drill program using our existing
infrastructure and access.”
1911 Gold has now completed s eventy (70) surface drill holes, for a total of 18,501.4 m of drilling. The
surface exploration drill program within the True North mine footprint is focused on new targets defined by
favourable host rocks and mineralized structural settings, also supported by significant historical drill
intercepts. The most recent phase of the program consisted of two drill rigs targeting the down-dip
extensions of mineralization at the SAM SE and San Antonio West (“SAM W”) targets, as well as testing
the emerging Shore target. The surface drilling program was completed on September 20, 2025, and the
project activities have now shifted to underground exploration, resource expansion and resource
delineation drilling. Underground drilling commenced on October 1, 2025, with one drill rig on Level 16 (695
m below surface) within the True North gold mine. Mobilization of a second underground drill rig is planned
for the second half of October.

San Antonio Southeast Target: Discussion of Results
Drilling completed to date has confirmed the extensions of gold mineralization within the SAM gabbro to
over 500 m southeast of the historically mined San Antonio zone, covering an area 400 m long and over
740 m to depth. Thirty-four (34) holes, for a total of 8,813.4 m, have been drilled on the SAM SE target area
as part of the current program . The results of six (6) drill holes for 2,347.0 m are included in this press
release, of which two (2) drill holes, TN-25-065A (26.0 m) and TN-25-068 (390.0 m), did not reach target
depths and were abandoned due to hole deviation.
The exploration drilling on the SAM SE target confirmed the presence of a vein system parallel to the
historical San Antonio ore body, which shares the same geological, 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 northeast and northwest trending shear zone corridors.
Drill hole TN-25-062, (7.05 g/t Au over 0.50 m; 6.21 g/t Au over 0.50 m; 7.03 g/t Au over 3.20 m, including
20.10 g/t Au over 0.50 m and 18.60 g/t Au over 0.50 m; and 7.38 g/t Au over 1.10 m, including 11.40 g/t Au
over 0.60 m) was drilled to test the extensions of mineralization to the west of drill hole TN-25-054 (13.90
g/t Au over 0.50 m, see press release dated August 7, 2025 entitled: 1911 Gold Intersects 5.52 g/t Au over
6.50 m and 54.00 g/t Au over 0.50 m on SAM Southeast Zone at True North . The hole intersected high-
grade mineralization within a wider zone approximately 30 m to the west of TN-25-054.
Drill hole TN-25-063 (19.40 g/t Au over 1.40 m; 5.46 g/t Au over 1.00 m; 4.37 g/t Au over 1.20 m and 6.74
g/t Au over 0.60 m), extended the high-grade gold mineralization 90 m to the west and 50 m down dip of
drill hole TN-25-062.
Drill hole TN-25-0 65 confirmed the down plunge extensions (over 740 m) of gold mineralization from
surface, intersecting 28.60 g/t Au over 0.50 m; 12.69 g/t Au over 2.40 m, including 15.20 g/t Au over 0.7 m
and 24.90 g/t Au over 0.70 m, and extended the gold mineralization from drill hole TN-25-054 (13.90 g/t Au
over 0.50 m)1, approximately 120 m deeper.

Shore Target: Discussion of Results
The newly identified Shore target is hosted within the same San Antonio gabbro unit and the intersection
of the 007 shear, which is located approximately 500 m southeast of L10 shear zone (SAM SE). Three (3)
holes for a total of 1,533 m have been drilled on the Shore target area as part of the current program
(including drill hole TN-25-019, which intersected 13.20 g/t Au over 0.50 m at a downhole depth of 253.0
m)². The results of two (2) drill holes for 1,210 m are included in this press release, which were drilled to
test the size potential of gold mineralization in drill step-outs from historical drill holes AB-07-003 (45.26 g/t
Au over 0.61 m) and AB-10-001 (5.34 g/t Au over 2.41 m) all within the Shore target area (see Technical
Report dated December 23, 2024 entitled “NI 43 -101 Technical Report on the True North Gold Project,
Bissett, Manitoba, Canada”).
Drill hole TN-25-070, intersected high-grade gold mineralization at a downhole depth of 503.40 m (33.80
g/t Au over 0.80 m), confirming the potential of this target for further drill testing.
Drill hole TN-25-069 intersected 6.05 g/t Au over 1.50 m at a downhole depth of 219.00 m within the L-10
zone hosted in the Shoreline Basalt.

San Antonio Southeast Target
The San Antonio Southeast target is located approximately 500 m southeast of the historically mined San
Antonio zone of the True North Gold mine. The San Antonio Southeast target occurs within the gabbro of
the San Antonio mafic unit and the intersection with the L-10 shear zone (Figure 1). 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 (see Figure 5).
Shore Target
The emerging Shore target has been identified through geological modeling, historical drilling and confirmed
with one previous exploration hole in 2025 (Drill hole TN-25-019 intersected 13.20 g/t Au over 0.50 m at a
downhole depth of 253.00 m, see press release dated April 1, 2025, entitled: “1911 Gold intersects up to
14.97 g/t Gold over 2.70 m including 71.60 g/t Au over 0 .50 m on SAM Southeast Zone at True North” ).
The Shore target is located to the southeast of SAM SE within the SAM gabbro on the intersection with the
007 shear zone corridor (Figure 1). The 007 shear hosts the historically mined 007 deposit hosted within
the Shoreline Basalt located to the east. The modelled target zone is open at depth. Drilling from surface is
limited due to the location of the upper section of the target area under Rice Lake.
Geological mapping is planned in the next few months to collect lithological and structural data from the
accessible underground mine levels , which coupled with the drill hole logging data, will support the
assessment and refinement of the geological interpretation and model.

Next Steps
With the completion of the latest phase of surface drilling within the mine lease, the focus is now on
mobilizing underground drill rigs to target areas within the True North gold mine footprint. Drilling will initially
focus on areas accessible from Level 16 (695 m below surface), as this area is drill-ready and provides
multiple favourable drill location options. The underground drill program is designed to continue extending
the first two surface discoveries at depth as well as drill test the new exploration targets (see press release
dated September 25, 2025, entitled “1911 Gold Commences Underground Drill Program at True North Gold
Project”). The program will also focus on delineation drilling of two test mining targets that are accessible
from Level 16, as well as target the extensions of the current resource, currently the focus of a Preliminary
Economic Assessment study (“PEA”), including preliminary mine plan.

Rehabilitation work will commence in two areas over the coming months: the L13 deposit area accessed
by ramp off the Hinge decline as well as Level 6, a previously unmapped area 262 m below surface,
extending to the northwest from the A shaft of the San Antonio deposit underground workings. The L13
mine area will give the Company better access to drill the down-dip extensions of the SAM SE target. Level
6 will support the continuation of drilling into the SAM W target, as well as potentially drill testing the
Cartwright Zone further west, an area containing a mineral resource inventory that remains open at depth.
Concurrently, the Company is permitting a 2,500 m drill program at Ogama-Rockland, which contains a
near-surface, high-grade 43-101 mineral resource (November 15, 2013, entitled: “A Technical Review Of
Ogama-Rockland Deposit on the Rice Lake Property, Manitoba, Canada.”, prepared by Watts, Griffis and
McOuat,) and is located 35 kilometres by road southeast of the True North gold mine complex. The
Company anticipates that the permits will be received in the coming weeks, allowing for this drill program
to commence prior to the end of 2025.
