Vancouver, British Columbia — January 19, 2026 — Leads & Copy — Endurance Gold Corporation (TSXV: EDG) has announced an initial inferred mineral resource estimate (MRE) of 19.6 million tonnes at 2.30 grams per tonne gold for 1.45 million ounces of gold at its 100%-owned Reliance Gold Project in southwest British Columbia, Canada.
The MRE, effective as of January 8, 2026, includes a near-surface inferred mineral resource of 15.6 million tonnes grading 2.23 grams per tonne gold for 1.12 million ounces of gold, and an underground inferred mineral resource of 4.0 million tonnes grading 2.58 grams per tonne gold for 0.33 million ounces of gold. The underground resource is open to expansion along strike and to depth.
The Reliance Gold Project is road accessible and located in the historic Bridge River Mining Camp, providing year-round access to existing infrastructure such as roads, hydro-electric power, water, and manpower. Initial metallurgical test work indicates positive gold recovery to a high-grade marketable gold concentrate.
Endurance Gold anticipates several near-term catalysts, including infill drilling to expand and upgrade the near-surface inferred MRE, deeper step-out drilling to expand the underground inferred MRE, and exploration drilling on surface geochemical anomalies along the Royal Shear trend and other gold-bearing structures.
The company also plans to continue metallurgy test work to optimize gold concentrate grade and recovery, as well as antimony recovery. Economic and engineering studies are slated to commence with the goal of completing a preliminary economic assessment (PEA) on the inferred MRE.
According to Robert T. Boyd, President and CEO, the MRE is a significant milestone for the Reliance Project, which originated as a grassroots discovery five years ago. Boyd also acknowledged the positive roles of the Tsal’alh and Xwisten First Nations communities in the project’s success, adding that the company plans to further demonstrate the project’s potential through resource expansion, drill testing, economic assessments, and community engagement.
The Reliance MRE incorporates the Imperial, Crown, and Eagle Zones within the Royal Shear. The MRE database consists of 11,763 samples collected from 34,850 m of diamond drilling (136 holes), 5,057 m of reverse-circulation drilling (71 holes), and 1,440 m of surface channel samples. Endurance Gold collected 91.3% of the samples.
The mineral resource estimate was prepared by Marc Jutras, P.Eng, M.A.Sc., Principal, Ginto Consulting Inc. Chris Martin, C.Eng, M.Eng, an independent metallurgical consultant, manages the metallurgy test work program. Darren O’Brien, P.Geo., Vice President Exploration of Endurance Gold Corporation, supervises the work program.
A technical report will be prepared and filed on SEDAR+ within 45 days of the press release.

Notes:
The MRE was completed by Ginto Consulting Ltd (“Ginto”). In accordance with the 2014 Canadian Institute of Mining, Metallurgy, and Petroleum (“CIM”) Definition Standards and Canadian National Instrument 43-101 (“NI 43-101”). Ginto is independent of Endurance Gold Corporation.
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.
Open Pit Mineral Resources are reported within a constraining pit shell optimized with the Lerchs-Grossmann algorithm in Maptek Vulcan using the following parameters: US$2,500 /oz Au, US$2.50 /t mining cost, US$14.00 /t processing cost, US$5.25 /t G&A cost, 81% Au recovery, and 47-degree pit slope.
Underground Mineral Resources are reported at an elevated cut-off grade of 1.0 gpt Au with a minimum mining width of 1.5 m.
Metallurgy gold recovery to concentrate estimated at 81%.
Rock density for major lithology units was based on 521 specific gravity measurements collected during the core logging procedure. Results were validated against 54 specific gravity measurements collected at the ALS Prep Lab from half-core samples prior to assay analysis. The average density is 2.76 g/cm3 for the MRE with a minimum of 2.70 g/cm3 and a maximum of 2.81 g/cm3.
Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability. The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, marketing, changes in global gold markets or other relevant issues.
The CIM definitions were followed for the classification of Inferred Mineral Resources. The quantity and grade of reported Inferred Mineral Resources in this estimation are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as Indicated Mineral Resources. It is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration.
