1911 Gold Files NI 43-101 Technical Report for the Ogama-Rockland Gold Project Updated Mineral Resource Estimate

1911 Gold Corporation has filed a National Instrument 43-101 Technical Report for its 100%-owned Ogama-Rockland Gold Project in southeastern Manitoba. The filing accompanies an updated underground Mineral Resource Estimate dated August 11, 2026.

The estimate defines an Inferred Mineral Resource of 3,314,000 tonnes at 6.68 g/t Au, containing 712,000 ounces of gold. This calculation utilizes a proposed economic cut-off grade of 2.50 g/t Au, with stopes designed via the Deswick 'Mineable Shape Optimizer' (MSO).

The project is located 45 km by road from the True North mill and sits within a ~62,000-hectare land package. Exploration upside remains open down-dip and along strike, with additional drilling planned for Q4 2026 to test resource expansion areas. Qualified Persons for the report are Tim Maunula, P.Geo (TMAC) and Roselyn Yeboah, P.Eng (1911 Gold).

1911 Gold Corporation (AUMB) has released an expected incremental update to the Ogama-Rockland resource, adding a high-grade satellite deposit averaging 6.68 g/t to its portfolio. This development supports the company’s district-scale strategy to feed ore to the True North mill. The resource is classified as Inferred, indicating a lower level of geological confidence that precludes its inclusion in economic studies or conversion to reserves without further drilling and technical work. Consequently, the update does not immediately alter the base-case PEA economics or the 2027 production timeline.

The announcement aligns with previous plans for a Q4 2026 global MRE and a planned test mining program. While the update validates the district's potential, it lacks the surprise or financial magnitude to be considered material, as the market has likely already priced in the satellite deposit's existence given prior drill results and the PEA's district-scale assumptions.

1911 Gold Corporation is an advanced-stage gold explorer and developer transitioning to a production-ready entity. Its flagship asset is the True North Gold Project, located in the Archean Rice Lake greenstone belt in Manitoba, Canada. The project is fully permitted and leverages existing, fully built infrastructure, including shafts, underground workings, a 1,350 tpd mill, and a tailings facility.

A Preliminary Economic Assessment outlines an 11-year mine life with steady-state production of approximately 58,114 oz of gold per year. Assuming a gold price of US$3,000/oz, the assessment projects an after-tax net present value of $391 million, an internal rate of return of 105%, and initial capital expenditures of $59 million.

The company also holds satellite assets, including Ogama-Rockland, located 45 km away, as well as Central Manitoba, Gunnar, and Jeep properties, within a roughly 62,000-hectare land package. No royalties are attached to these properties. 1911 Gold Corporation aims to restart operations in 2027, leveraging existing infrastructure to minimize capital expenditures and rapidly generate cash flow.
