Vancouver, British Columbia — February 25, 2026 — Leads & Copy — Endurance Gold Corporation (TSXV: EDG, OTCQB: ENDGF, FSE: 3EG) has announced the filing of a National Instrument 43-101 (NI 43-101) Technical Report supporting an inaugural Mineral Resource Estimate (MRE) at its 100%-owned Reliance Gold Project in British Columbia, Canada.
The technical report, titled “NI 43-101 Mineral Resource Estimate and Technical Report on the Reliance Gold Project, British Columbia, Canada,” is available on SEDAR+ and the company website. Ginto Consulting Ltd prepared the report, which accompanies the public disclosure of the inaugural MRE published on January 19, 2026, with an effective date of January 8, 2026.
The report highlights an Inferred MRE of 19.6 million tonnes at 2.30 grams per tonne gold for 1.45 million ounces of gold. The mineral resource is road accessible in the historic Bridge River Mining Camp, with year-round access to infrastructure.
The near-surface inferred mineral resource is estimated at 15.6 Mt grading 2.23 gpt Au, for 1.12 Moz contained gold reporting to the open pit. The underground inferred mineral resource is estimated at 4.0 Mt grading 2.58 gpt Au for 0.33 Moz contained gold and is open to expansion along strike and to depth.
Initial rougher flotation test work indicates 84.7% gold recovery to a marketable concentrate. A gold recovery of 81% to a high-grade cleaner concentrate has been assumed for the MRE.
Near-term upside catalysts include infill drilling within the constraining pit shell to expand and upgrade the near-surface Inferred MRE, deeper step-out drilling to expand the underground Inferred MRE, exploration drilling on the untested Eagle Offset and Olympic surface geochemical anomalies, ongoing metallurgy test work focusing on gold concentrate grade and recovery optimization and antimony recovery, and commencing economic and engineering studies with the goal of completing a Preliminary Economic Assessment (PEA) on this Inferred MRE.
The MRE was completed by Ginto Consulting Ltd, independent of Endurance Gold Corporation, in accordance with the 2014 Canadian Institute of Mining, Metallurgy, and Petroleum (CIM) Definition Standards and Canadian National Instrument 43-101 (NI 43-101).
Mineral Resources are estimated at a base case cut-off grade of 0.30 gpt Au for open pit (Zone OP), and 1.0 gpt Au for underground (Zone UG) with an effective date of January 8, 2026.
Metallurgy gold recovery to concentrate estimated at 81%.
The report recommends a 10,000 m drilling program within the MRE, including infill drilling to upgrade Inferred Mineral Resources, step-out drilling to test the limits of the mineral resource, and deeper exploration drilling on areas of higher-grade below the MRE constraining pit shell.
The program also recommends continued metallurgy test work, advancing new priority exploration targets at Eagle Offset and Olympic, and continue advancing environmental, community and mining studies.
A proposed budget including contingencies of C$10.1 million is recommended.
Marc Jutras, P.Eng, M.A.Sc., Principal, Ginto Consulting Inc., prepared the Mineral Resource Estimate. Chris Martin, C.Eng, M.Eng, manages the metallurgy testwork program. Darren O’Brien, P.Geo., Vice President Exploration of the Company, supervises the work program. The Qualified Persons have reviewed and approved the scientific and technical information.
Endurance Gold Corporation is focused on the acquisition, exploration and development of North American mineral properties. The company’s exploration focus is currently to advance the Reliance Gold Project, located near Gold Bridge B.C. in the historic Bridge River Gold Mining Camp.
