Drill Results

1911 Gold Intersects up to 58.66 g/t Gold over 1.40 m on San Antonio

West Zone at True North

Vancouver, British Columbia, June 10, 2025 – 1911 Gold Corporation ("1911 Gold" or the "Company")

(TSXV: AUMB; OTCBB: AUMBF; FRA: 2KY) is pleased to announce the assay results from twelve (12) drill

holes for 3,208.0 metres (“m”) from the ongoing surface drill program at the True North Gold Project. The

True North project , including a permitted mill, camp, and tailings facility, is centrally located within the

Company’s 100%-owned Rice Lake Gold property in southeast Manitoba, Canada.

Highlights:

• Drilling has continued to expand the near-surface quartz vein hosted gold (“Au”) mineralization

on the new San Antonio West (“SAM West”) target along strike and to depth

San Antonio West Target

• Drill results confirmed the western and down dip extensions of gold mineralization within the

prolific San Antonio mafic unit up to 350 m down dip and 500 m along strike, including:

- TN-25-057: Intersected 58.66 grams per tonne (g/t) Gold (Au) over 1.40 m at a downhole

depth of 145.00 m, including 63.20 g/t Au over 0.90 m and 50.50 g/t Au over 0.50 m

- TN-25-056: Intersected 9.59 g/t Au over 2.30 m at a downhole depth of 103.10 m, including

11.25 g/t Au over 1.80 m, including 21.30 g/t Au over 0.50 m

- TN-25-058: Intersected 10.40 g/t Au over 1.00 m at a downhole depth of 249.30 m

“These are some of the best results we’ve seen to date from the San Antonio West target .”, Shaun

Heinrichs, CEO and President, stated, “The drilling confirms the potential definition of high-grade ore shoots

within the SAM West target zone, and further supports our geological model. These results build the case

for continued underground exploration, where we see significant potential to define and expand new and

existing mineral resources within the mine infrastructure.”

1911 Gold has completed fifty-one (51) surface drill holes, for a total of 11,695. 4 m on the current drill

program, which commenced in October 2024 on new exploration targets located within the True North Gold

mine footprint. The results of seven (7) new drill holes for 1,928.0 m from the San Antonio West target and

five (5) initial drill holes for a total of 1,280.00 m from the Gate target are included in this release. New

targets have been generated and drill tested within prospective host rock s and mineralized structural

settings, including significant historical drill results. The results from nine (9) additional exploration drill holes

are currently pending. Additional drill planning is underway on the San Antonio West and San Antonio

Southeast targets and will commence when access to the Mine site is permitted (see press release entitled

“1911 Gold Temporarily Suspends Operation at True N orth Complex due to Bissett Evacuation Order” ,

dated May 30, 2025). The exploration drilling plan includes up to 30,000 m of drilling by the end of 2025.

San 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 west of the historically mined San Antonio zone, covering an area 500 m long and over 260 m

to depth, dipping 50 º to the northeast . Twenty-one (21) drill holes for a total of 4,220.0 m have been

completed to date on the SAM West target area.

The latest drill holes, comprised of seven (7) new drill holes for 1,928.0 m, extended the footprint of

mineralization 100 m down dip from the results announced on April 30, 2025 (see press release entitled

“1911 Gold Intersects 62.40 g/t Au over 1.00 m on San Antonio West at True North”).

Drill hole TN-25-056, designed to undercut high grade gold mineralization intersected in drill hole TN -25-

037 (1.00 m @ 8.73 g/t Au, 1.00 m @ 62.40 g/t Au and 0.70 m @ 6.09 g/t Au and 4.50 m @ 4.17 g/t Au),

intersected 2.30 m @ 9.59 g/t Au, including 1.80 m @ 11.25 g/t Au and 0.50 m @ 21.30 g/t Au. Drilling

successfully extended the gold mineralization approximately 50 m down dip and returned high-grade gold

results.

Drill hole TN -25-057 (1.40 m @ 58.66 g/t Au) tested the down- dip extensions of the high- grade gold

intercepts of previously released holes TN-24-043 (1.00 m @ 12.50 g/t Au) and TN-24-045 (3.70 m @ 6.84

g/t Au, including 1.40 m @ 12.40 g/t Au and 2.70 m @ 5.30 g/t Au, including 0.50 m @ 11.30 g/t Au). Drilling

successfully intercepted high-grade gold mineralization approximately 160 m down dip.

Drill hole TN-25-058 (0.50 m @ 10.40 g/t Au) designed to test the 160 m down- dip extension of the gold

mineralization from hole TN-25-056, intersected three distinct gold mineralized veins extending the multiple

vein structures to 340 m depth.

Drilling has further confirmed the existence of up to three (3) vein zones hosted within the target gabbro

unit, supporting the potential to mine multiple zones on levels as conducted historically (see press release

entitled “1911 Gold Intersects 62.40 g/t Au over 1.00 m on San Antonio West at True North”, dated April

30, 2025). Planning for the next phase of drilling on the SAM West target is ongoing.

San Antonio West Target

The San Antonio West target is located west of the historically mined San Antonio zone of the True North

Gold Mine. The San Antonio West 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). Drilling has now

confirmed gold mineralization in quartz -carbonate shear veins with sericite, chlorite, minor tourmaline

alteration and up to 2% disseminated and veinlet-hosted pyrite. The target occurs as a vein system parallel

to the San Antonio Mine ore body, with the same geological, alteration and mineralization characteristics.

Gold mineralization has been traced over a strike length of 500 m and to 360 m down di p.

Gate Target

The Gate target was defined to explore for potential gold mineralization on the intersection of the Cartwright

South and L13 shear zone s with the Shoreline Basalt unit. Five (5) drill holes, totalling 1,280.00 m (see

Table 3), were completed on this target. All drill holes intercepted well-developed quartz veining hosted

within sediments, with drill hole TN -25-044 intersecting 0.90 m @ 1. 30 g/t Au and drill hole T N-25-049

intersecting 0.90 m @ 0.57 g/t Au. Drilling did not intersect wide sections of basalt, which host the majority

of mineralization in this unit at True North. Additional interpretation is ongoing to define the basalt flows

within the Shoreline Basalt unit, which in this area appear to occur as discontinuous lenses intercalated

within sediments. Interpretation, modelling and drill targeting are ongoing to define potential extensions of

the basalt unit hosting gold mineralization.

Site Access Update

Recent rainfall, favourable winds, and cooler temperatures have eased wildfire conditions in the region;

however, the Town of Bissett and the Company’s True North site remain under evacuation as a

precautionary measure. Fire crews continue to make progress in the area. Company facilities have not

been impacted, and the Company expects to resume site activities once it is deemed safe to do so.

Next Steps

Building on the strong results achieved to date on new exploration targets and the compelling targets to

expand the current resource, 1911 Gold is advancing plans to initiate underground exploration drilling. Once

site access is re-established, the Company will continue preparing multiple underground levels to facilitate

this next phase of work. Targeting is well underway, focusing on high-priority areas that offer meaningful

resource expansion potential and support the mine plan currently under development. Mobilization of drill

rigs to key underground levels is expected later this summer. Concurrently, the Company is actively

evaluating additional targets across the property and advancing the redevelopment of the high-grade, near-

surface Ogama-Rockland 43-101 mineral resource, located 25 km by road east of the True North complex.
