1911 Gold Intersects up to 58.66 g/t Gold over 1.40 m on San Antonio West Zone at True North

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 rocks 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 North 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.

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 west of the historically mined San Antonio zone, covering an area 500 m long and over 260 m to depth, dipping 50º 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 dip.

Gate   Target

The Gate target was defined to explore for potential gold mineralization on the intersection of the Cartwright South and L13 shear zones 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 TN-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.
