VANCOUVER, British Columbia — November 6, 2025 — Leads & Copy — Endurance Gold Corporation has announced assay results from six additional drill holes at its Reliance Gold Project’s Crown Zone, revealing promising gold and antimony mineralization. The company also provided an update on its inaugural Mineral Resource Estimate, metallurgical testing, and new target generation efforts.
Four drill holes tested the Lower Crown target, and two tested the Upper Crown target, both discoveries from the 2024 drilling program. According to President and CEO Robert T. Boyd, the 2025 drilling program at the Crown Zone represents a significant milestone, demonstrating the potential for continuous mineralization along the 1.5-kilometer Royal Shear trend, encompassing both the Imperial and Eagle Zones.
Drill hole DDH25-122A intersected the Royal Shear structure, returning 14.03 grams per tonne (“gpt”) gold & 1.46% antimony (“Sb”) over 5.2 metres (“m”), a 30 m step-out from Lower Crown hole DDH25-113 that returned 5.63 gpt gold over 3.3 m, and an 85 m step-out southeast from Imperial Zone. Drill hole DDH25-125 returned 6.10 gpt gold & 0.22% Sb over 10.0 m within the mineralized Royal Shear structure 50 m up-dip from the Lower Crown discovery hole of 7.61 gpt gold and 0.75% Sb over 5.7 m. Drill holes DDH25-126 and DDH25-127 targeted the Royal Shear structure up-dip of DDH25-125 but intersected a fault-displaced chert unit instead.
Drill holes DDH25-123 and DDH25-124 tested for continuation of the Upper Crown Zone along strike from the discovery hole DDH24-093 that intersected abundant Visible Gold within a quartz-carbonate vein assaying 147.5 gpt gold over 1.0 m. DDH25-123 returned 10.08 gpt gold over 3.8 m, including 17.38 gpt gold over 1.8 m, and DDH25-124 returned 1.83 gpt gold over 7.3 m, including 5.87 gpt gold over 1.3 m. The Upper Crown Zone discovery remains open in all directions.
The 2025 drilling program was designed to test the Crown “Gap,” a previously insufficiently drilled section of the Royal Shear connecting the Imperial and Eagle Zones, with 13 drill holes intersecting greater than 10 gram*metres. Several 2025 holes returned multiple gold interceptions.
The company completed 6,864 m of diamond drilling in 20 drill holes in 2025 at its Reliance Gold Project. Gold assays have now been received for all drill holes and incorporated into the updated 3D geology model. The Reliance drill hole database now consists of 11,986 samples collected from 35,127 m of diamond drilling, 6,045 m of RC drilling, and 1,512 m of surface channel samples. Ginto Consulting Inc. was contracted to complete the Mineral Resource Estimate. The company anticipates completion of the inaugural Mineral Resource Estimate by year-end or early in the New Year.
Concurrently with the Mineral Resource Estimate, metallurgical testwork is in progress, focusing on flotation and associated testwork to maximize recovery to a high-grade gold (antimony) sulphide concentrate.
During the 2025 field season, over 1,500 soil samples and 150 rock samples were collected, and assays are pending. Prospecting, mapping, and preliminary portable XRF (pXRF) analysis indicate potential for discovery of several new gold prospects on trend of the Royal Shear as well as on several parallel structural trends.
All drill assay results are reported as core length intervals. True composite widths are estimated at 80% to 100% of core length. Diamond drill core was logged and evaluated on the Property, and samples designated for assay analysis were collected under the supervision of a geologist at the property. All drill core samples have been submitted to ALS Global in North Vancouver, BC.
Endurance Gold monitors QA/QC by inserting blanks, certified standards, and pulp duplicates into the sample stream. The work program is supervised by Darren O’Brien, P.Geo.
