1911 Gold Reports High-Grade Drill Results from Ogama-Rockland Intersecting 10.41 g/t Gold over 3.40 m, including 32.40 g/t Gold over 1.00 m

Press Release

Vancouver, British Columbia, May 26, 2026 – 1911 Gold Corporation (“1911 Gold” or the “Company”) (TSXV: AUMB; OTCQX: AUMBF; FRA: 2KY) is pleased to provide assay results from the surface resource expansion and confirmation diamond drill program at the Ogama-Rockland Gold Deposit (“Ogama-Rockland”), located approximately 45 kilometres (“km”) by road, southeast of the operational and fully permitted True North Gold Project (“True North”), located in southeast Manitoba, Canada.

Ogama-Rockland is one of several historical gold producers within trucking distance of the True North mine and mill complex (the “True North Complex”), underscoring the district-scale exploration upside of 1911 Gold’s land package. The deposit hosts a current NI 43-101 inferred resource (“2013 MRE”), as detailed in the technical report dated November 15, 2013, entitled, “A Technical Review of the Ogama-Rockland Deposit on the Rice Lake Property, Manitoba, Canada, for Bison Gold Resources Inc.”, prepared by Watts, Griffis and McOuat.

This program consisted of eight (8) surface diamond drill holes for 2,410 metres (“m”) designed to confirm the updated geological interpretation and test the extensions of the mineralized veins outside of the 2013 MRE. In addition, the Company sampled the drill core from 15 historical drill holes for 429 m (totaling 439 samples) previously not sampled, in preparation for an updated mineral resource estimate expected towards the end of the second quarter of 2026 (“Q2-2026”).

Drilling Highlights:

• The drill program was designed to improve confidence in the new geological model, assess vein continuity along strike, and test the extensions of the high-grade veins down-plunge and along strike
• Drill results from the surface resource expansion and confirmation drilling program recently completed at Ogama-Rockland returned the following highlighted results:
  • OR-25-001: Intersected 10.41 grams per tonne gold (“g/t”, “Au”) over 3.40 m (at 343.80 m downhole depth), including 32.40 g/t Au over 1.00 m
  • OR-26-004: Intersected 46.10 g/t Au over 0.60 m (at 74.30 m downhole depth)
  • OR-25-001: Intersected 7.84 g/t Au over 0.70 m (at 38.20 m downhole depth)
  • OR-26-004: Intersected 5.57 g/t Au over 0.80 m (at 248.00 m downhole depth)
  • OR-26-006: Intersected 3.51 g/t Au over 1.00 m (at 158.30 m downhole depth)
• Assay results from sampling of historical drill core returned the following significant results:
  • OG-11-008: Intersected 18.10 g/t Au over 0.70 m (at 272.30 m downhole depth)
  • OG-11-008: Intersected 3.21 g/t Au over 1.21 m (at 277.26 m downhole depth)
• 1911 Gold is in the process of updating the mineral resource estimate for Ogama-Rockland, expected towards the end of Q2-2026
• Metallurgical test work is being conducted on a composite drill core sample to confirm the suitability of the True North processing facility for the recovery of gold from Ogama-Rockland
• Upon completion of the updated mineral resource estimate, Ogama-Rockland will be considered for inclusion in an updated and expanded PEA

Shaun Heinrichs, President and CEO, stated, “We are extremely pleased to have completed this recent surface drill program at Ogama-Rockland, which was last drilled by the Company in 2018, returning encouraging results. Ogama-Rockland is one of our high-priority regional targets that illustrates the district-scale hub-and-spoke opportunity to provide long-term production growth for the operations and is located approximately 45 km southeast of True North via a provincial highway. Drilling confirmed our new geological model and intersected high-grade intercepts within and as extensions to the resource. In addition, we have confirmed high-grade gold mineralization in historical core not previously sampled as well as from our 2018 infill drilling not included in the current resource, which encountered a number of high-grade intercepts, all of which will be included in the new mineral resource update.

Ogama-Rockland will be included in the updated and expanded PEA, following completion of a global resource update expected in the fourth quarter of this year. The updated and expanded PEA will aim to highlight future expansion opportunities as we continue to unlock the potential within the True North mine and across our significant and prospective land position.”

Discussion of Results – Ogama- Rockland Resource Expansion and Confirmation Drilling

Ogama-Rockland is the most advanced regional target situated in the southeast portion of the Company’s Rice Lake Exploration Properties, in an area with a number of historical high-grade gold producers and prospective exploration targets. Ogama-Rockland is accessed from True North by provincial road over approximately 45 km trucking distance.

The Ogama-Rockland gold deposit is comprised of the historic Ogama and Rockland producing gold mines, which collectively produced approximately 45,000 oz of gold between 1948 and 1951 at a grade of 11.20 g/t Au (refer to the technical report as noted above). The deposit is hosted in steeply north-east dipping north-west trending quartz shear veins and stockworks with associated pyrite, chalcopyrite, pyrrhotite mineralization and sericite, chlorite alteration, located in brittle-ductile structures within a multiphase tonalite-granodiorite on the southeast margin of the Ross River pluton. The veins have been traced for over 1,500 m and drilled to depths of 400 m. Nine (9) major veins have been modelled within the main area of the mineralized system and confirmed in recent drilling with five (5) additional subordinate parallel veins modelled.

The drill program was designed to confirm the occurrence and extensions of modelled veins to the northwest over a distance of 200 m beyond previous drilling and to test the extensions of veining to the southeast in one drill hole in an 85 m step-out. The updated interpretation of the modelled veins was confirmed in all eight (8) drill holes intersecting the quartz veins as predicted. Seven (7) of the eight (8) drill holes intersected significant gold mineralization associated with the modelled veins.

Drill hole OR-25-001 was collared 40 m to the southeast of historical drill hole OG-12-025 (18.82 g/t Au over 1.52 m at a downhole depth of 683.63 m), intersecting all of the veins targeted, and confirming the down-dip extensions of the V06 vein by over 50 m, intersecting 10.41 g/t Au over 3.40 m (at 343.80 m down hole depth), including 32.40 g/t Au over 1.00 m and extending the V40 vein at depth by over 75 m, intersecting 1.66 g/t Au over 1.10 m (at 405.60 m downhole depth).

Drill hole OR-25-002, was drilled as a 60 m step-out to the northwest of drill hole OR-25-001 intersecting the veins as predicted but with no significant results. Drill hole OR-25-003, a 45 m step out to the northwest of hole OR-25-002, intersecting the veins as modelled and returning 0.33 g/t Au over 3.20 m at 251.0 m downhole depth.

Drill hole OR-26-004, an 85 m step out to the northwest of hole OR-25-003, confirming the V01, and V02 veins intersecting 2.55 g/t Au over 1.00 m at 179.20 m downhole depth, and 46.10 g/t Au over 0.60 m (at 74.30 m downhole depth), and extended the depth extensions of the V40 vein by over 50 m, intersecting 5.57 g/t Au over 0.80 m (at a 248.00 m downhole depth).

Drill hole OR-26-005 was drilled as a 50 m step out to the northwest of hole OR-26-004, confirming vein V01, intersecting 3.39 g/t Au (at a downhole depth of  208.20 m) and vein V06 intersecting 3.51 g/t Au over 1.00 m (at a downhole depth of 158.30 m).

Drill hole OR-26-006 was drilled to undercut the vein system by 50 m below drill holes OR-26-004 and OR-26-005, intersecting vein V02 returning 3.51 g/t Au over 1.00 m (at 158.30 m downhole depth).

Drill hole OR-26-007 was drilled to undercut the vein system by 80 m below drill hole OR-26-004, confirming the depth extensions of the V04 and V06 veins intersecting up to 1.09 g/t Au over 3.00 m at 338.00 m downhole depth.

Next Steps

All drilling data, including the previously unsampled drill core data from historical drilling and the 2018 drilling will be used in preparation of an updated mineral resource estimate for Ogama-Rockland, expected towards the end of Q2-2026. Once finalized, the new resource at Ogama-Rockland will be reviewed for upside and expansion potential with additional drilling and development work planned as warranted.

The Company is in the process of planning new drill programs on two target areas located within the southeast extensions of the Rice Lake greenstone belt,  an area ranging from 30 km to 50 km from True North. Drilling is planned for the second half of the year.

A composite sample was collected from the new Ogama-Rockland core and sent to ALS Canada Ltd. (Metallurgy Services), Kamloops, Canada for metallurgical recovery test-work, results will be released when the test has been completed.

Following the completion of the current exploration drill program at True North, the Company will prepare an updated mineral resource estimate for True North which will include the resource expansion drilling and drilling from the new near-mine exploration targets, the San Antonio Mine West, San Antonio Mine Southeast, and the Shore targets. The updated mineral resources at Ogama-Rockland and True North will form the basis of an updated and expanded PEA expected to commence in the fourth quarter of this year.

This initiative positions the Company for future growth by leveraging existing infrastructure at the True North Complex to advance regional resource development.
