1911 Gold Advances True North Toward 2027 Production with Start of Underground Development and Test Mining Preparation

Press Release

Vancouver, BC, May 19, 2026 – 1911 Gold Corporation (“1911 Gold” or the “Company”) (TSXV: AUMB; OTCQX: AUMBF; FRA: 2KY), an advanced-stage gold exploration and development company advancing the fully built and permitted True North Gold Project (“True North”) towards production in 2027, is pleased to announce that development crews have commenced drift development on Level 16 of the True North Mine, located in Southeastern Manitoba, Canada, and provides an operational update on other development activities in preparation for test mining later this year.

True North Operational Highlights

• Underground development commenced at True North, advancing the project towards 2026 test mining and planned 2027 production
• Infill and delineation drilling is focused on the L10 and Hinge zones (see Figure 1), two areas targeted for test mining as they are expected to provide critical operational data to support ongoing mine planning and preparations for 2027 production
• Key underground readiness activities have been significantly advanced, including infrastructure upgrades and rehabilitation, and completion of a critical second egress for Level 16
• Development activities are now focused on ramp access, sill drives and essential infrastructure required to prepare the designed stopes for extraction
• Development and execution capacity is increasing with the underground development contract awarded and additional underground equipment arriving in the coming months

Éric Vinet, Chief Operating Officer, stated, “Development crews blasted their first round at the end of April, initiating development in one of the potential target areas designated for test mining activities this year. Our focus is on safely advancing access and opening the necessary mining blocks for our bulk sample program and other test mining activities, which will continue through 2026. Material recovered from test mining will be stockpiled underground and skipped to surface once the loading pocket on Level 26 is operational. The stockpiled material will be processed following completion of the new crushing circuit in preparation for production next year.”

Underground predevelopment activities advanced on multiple fronts during the first quarter of 2026, establishing the foundation for a return to active mining. Predevelopment activities included dewatering (ongoing), electrical and ventilation upgrades, communications infrastructure, rehabilitation and ground support in select areas, refuge station re-establishment, blasting line inspection and repair from surface to Level 16, and equipment repairs and procurement. A significant milestone was achieved with the completion of the second egress rehabilitation from Level 16 to surface, a critical step toward resuming active mining operations.

The L10 and Hinge zones are the primary targets for test mining activities, selected for their potential to provide critical data to reconcile current block models and optimize the longitudinal narrow-vein mining method selected for these zones. With initial equipment successfully lowered to Level 16, underground development commenced at the end of April on the L10 Zone, a higher-grade mineralized area accessed from Level 16.

Development work includes ramp development for primary access to the designed stopes, sill drives to expose and define modelled veins, and essential infrastructure such as level access, remuck bays, and ventilation (see Figure 2). Initial work is focused on completing the first 140 m of ramp access into the L10 target area (see Figure 3) to support drill bay access for infill and delineation drilling. Delineation drilling on the lower portion of the Hinge Zone has been completed from Level 16, with stope planning and design now being finalized.

The Company has awarded an underground development contract with mobilization anticipated in June 2026. The addition of a dedicated contract mining crew is expected to accelerate development rates toward the Company’s test mining objectives. In parallel with development activities, a diamond drill program commenced on several targets on the upper portion of the Hinge Mine. Up to five targets are being evaluated for test mining from the Hinge ramp, of which three have been rehabilitated and are ready for infill and delineation drilling.

Next Steps

The preliminary mine plan estimates 3,551 metres (‘m”) of total new development to prepare designed stopes for extraction, including 2,056 m of development for the Hinge target area and 1,495 m for the L10 target area, including:

• 2,160 m of ramp development to provide primary access to the designed stopes
• 1,391 m of sill drives to expose and define the modelled veins
• Essential infrastructure, including level accesses, remuck bays, and ventilation raises

Additional underground equipment is on order, including three 2-yard scoops arriving in June and a single-boom jumbo arriving in July, which will meaningfully increase development capacity as the program ramps up.

The Company will provide operational updates as underground activities continue to progress and major milestones are achieved.

About 1911 Gold Corporation

1911 Gold is an advanced gold explorer and developer focused on its 100%-owned True North Gold Project in the Archean Rice Lake Greenstone Belt in Manitoba, Canada. The Company controls a large, highly prospective ~62,000-hectare land package with numerous past-producing gold operations within trucking distance of the fully built and permitted True North mine and mill complex. 1911 Gold is positioning itself to restart operations in 2027 and offers a unique, near-term production opportunity with significant exploration upside. The strategy is to build a district-scale gold mining operation around a central, and readily expandable infrastructure complex to support a socially and environmentally responsible, long-term mining operation with little development risk and a growing mineral resource base.

1911 Gold’s True North complex and the exploration land package are located within and among the First Nation communities of the Hollow Water First Nation and the Black River First Nation. 1911 Gold looks forward to maintaining open, cooperative, and respectful communications with all of our local communities and stakeholders to foster mutually beneficial working relationships.
