1911 Gold Corporation (TSX-V: AUMB) (OTCQX: AUMBF) (FRA: 2KY) is pleased to announce assay results from the surface exploration drill program at San Antonio West 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.

Drilling Highlights:

• Drilling confirmed the continuity of gold mineralization within a gap area of the previously drilled SAM W target measuring approximately 200 metres deep and 200 m in strike length between depths of 230 m and 430 m from surface on the northwest extensions of the target area, and returned the following highlighted results:
  • TN-26-073: Intersected 11.31 grams per tonne Au over 1.70 m (at 391.10 m downhole depth), including 16.20 g/t Au over 0.80 m
  • TN-26-089: Intersected 5.72 g/t Au over 3.00 m (at 327.40 m downhole depth), including 9.65 g/t Au over 1.10 m
  • TN-26-082: Intersected 6.79 g/t Au over 2.40 m (at 204.40 m downhole depth), including 7.98 g/t Au over 1.40 m
  • TN-26-097: Intersected 11.80 g/t Au over 0.50 m (at 361.40 m downhole depth)

Shaun Heinrichs, President and CEO, stated, “We are pleased with the continuity of gold mineralization and the extent of the mineralized vein system at SAM W, which we have continued to intersect in our resource definition drilling, along with a number of high-grade gold intercepts. The three near-mine targets discovered in 2024 (SAM W, SAM SE and Shore) are encouraging given their high-grade nature and their occurrence at higher elevations at True North compared to the currently defined resource. Drilling in support of the resource update is now complete and geological modelling is underway, keeping us on track to deliver an updated global resource estimate in the fourth quarter of this year. As we continue to develop these targets, we expect them to have a significant, long-term impact on the production potential at True North.”

The latest assay results are from eight surface diamond drill holes for 2,980 m from the exploration drilling program testing the resource potential of the SAM W target located adjacent to existing infrastructure at True North. Drilling was conducted from surface to define the strike and depth extensions of previously released drill results from SAM W during 2025 and 2026 (see Figure 1). One drill hole, TN-26-097A, did not reach target depth and was abandoned. The Company has now completed thirty-four (34) drill holes for a total of 9,067 m at SAM W, where two (2) drill holes, TN-25-071A and TN-26-097A, did not reach target and were abandoned. All results from SAM W will support a maiden mineral resource estimate.

San Antonio West Target: Discussion of Results

The latest surface exploration drilling at SAM W confirmed the continuity of mineralization within a gap in previous drilling over an area measuring 200 m in elevation and 200 m along strike length from depths of 230 m to 430 m from surface within the northwest extensions of the target area. The latest results confirmed continuity of high-grade vein-hosted gold mineralization to the northwest, hosted within the San Antonio gabbro unit, adjacent to the intersection with the regional Cartwright South shear zone. Drilling in the current program has now confirmed continuous mineralization at SAM W over a strike length of 500 m and to down-plunge depths of over 600 m and remains open at depth. The historical San Antonio mine is located in the same geological setting approximately 500 m to the south. The mineralized intercepts are characterized by quartz-carbonate shear veins predominantly striking east-west and dipping steeply to the north and vein breccias trending northwest and dipping to the northeast with sericite, ankerite and chlorite alteration, associated with pyrite disseminated and in veinlets. All seven (7) drill holes that reached target depth confirmed the continuity of the target and intersected mineralization in veining within the SAM gabbro host.

Drilling confirmed the extensions and continuity of the SAM W vein system above and to the northwest of previous drill hole TN-25-064¹ which intersected 24.83 g/t Au over 2.60 m, including 46.00 g/t Au over 1.00 m (at 490.00 m downhole depth) and drill hole TN-25-071¹ which intersected 12.80 g/t Au over 0.80 m (at 473.50 m downhole depth). Drilling confirmed the continuity of mineralization below and to the northwest of hole TN-24-006² which intersected 3.70 g/t Au over 4.84 m (at 125.38 m downhole depth), including 7.23 g/t Au over 1.05 m and 8.42 g/t Au over 0.91 m.

Drilling also extended mineralization along strike to the northwest of previous drill hole TN-25-057³ which intersected 58.66 g/t Au over 1.40 m (at 145.00 m downhole depth), including 63.20 g/t Au over 0.90 m and 50.50 g/t Au over 0.50 m, all within the same geological setting.

Next Steps

Additional underground exploration drilling from the Hinge decline is underway, testing the depth extensions of SAM SE and is expected to be completed by the end of August.

Geological wire-frame modelling of the veins has commenced in preparation for a maiden resource estimate on the SAM W, SAM SE and Shore targets, with the updated global resource estimate expected in the fourth quarter of this year.

Current drilling activities are being conducted from underground with three (3) drill rigs focused on infill and delineation drilling of areas contemplated for test mining and the early years of the Preliminary Economic Assessment (“PEA“) mine plan. Two (2) underground drill rigs are active on Level 16, and a third is operating from the Hinge decline. A fourth drill rig will be mobilized upon completion of rehabilitation on Level 26.

Qualified Person Statement

The scientific and technical information in this news release has been reviewed and approved by Mr. Michele Della Libera, P.Geo., Vice-President Exploration of 1911 Gold Corporation, who is a “Qualified Person” as defined under NI 43-101.

Quality Assurance/Quality Controls

Oriented core samples are collected by sawing the drill core in half along its axis; one half is sampled, placed in plastic sample bags, labelled and sealed, and the other half is retained for future reference. Batches are shipped to Activation Laboratories Ltd. (Actlabs), in Thunder Bay, Ontario, for sample preparation and analysis. Samples are dried, crushed to 2 mm and a 1 kg split is pulverized to -200 mesh. Gold analysis is completed by fire assay with an atomic absorption finish on 50 grams of prepared pulp. Samples returning values equal to or greater than 10.00 g/t Au are re-analyzed by fire assay with a gravimetric finish. Total gold analysis (Screen Metallic Sieve) is conducted on highly mineralized samples or samples containing visible gold. Certified gold reference material samples are inserted every 20 samples and blank samples at intervals of one in every 50 samples, with additional blanks inserted after samples hosting visible gold. Repeat third-party gold analyses are conducted on 5% of all submitted sample pulps at ALS-Chemex Laboratory, North Vancouver, Canada.
