Endurance Reports Four Additional Holes with Highlight Intersections of 5.13 gpt Gold over 19.8 Metres and 5.40 gpt Gold over 4.8 Metres

MWN-AI** Summary

Endurance Gold Corporation has announced promising assay results for four additional drill holes at its 100%-owned Reliance Gold Project in British Columbia. Key highlights from the drilling campaign include significant gold mineralization found in the Crown "Gap" Zone and the Imperial Zone. Notably, drill hole DDH25-117 returned an impressive 5.13 grams per tonne (gpt) gold and 0.75% antimony (Sb) over 19.8 meters, including a higher-grade interval of 7.70 gpt gold over 9.2 meters. This hole confirmed the mineralized Royal Shear structure within the Imperial Zone and was drilled to obtain material for ongoing metallurgical testing.

In the newly explored Crown "Gap" Zone, drill hole DDH25-121 also showed promising results, returning 10.15 gpt gold over 1.5 meters and intersecting a mineralized ultramafic-chert contact with an assay of 5.40 gpt gold over 4.8 meters, including a standout interval of 12.0 gpt gold over 1.0 meter. These recent drill results indicate a potential for mineralized continuity along the 1.5-kilometer Royal Shear trend, stretching from the Imperial Zone to the Upper Eagle Zones.

Overall, the Crown Area has shown a high rate of success, with twelve of the eighteen drill holes resulting in significant mineralization. The company’s President & CEO, Robert T. Boyd, emphasized the uniqueness of ultramafic-associated gold mineralization in this area, bolstering the viability of further exploration and development. With twenty holes drilled to date in the 2025 program, ongoing activities include resource modeling and metallurgical testing, alongside continued geological mapping and soil sampling efforts.

MWN-AI** Analysis

Endurance Gold Corporation's recent assay results from the Reliance Gold Project have reinforced the company’s growth potential and strengthened its market position, particularly with significant discoveries in the Crown "Gap" Zone and Imperial Zone. Drill hole DDH25-117's impressive intersection of 5.13 grams per tonne (gpt) gold over 19.8 meters signals robust mineralization and further establishes the area's viability. Additionally, DDH25-121’s 5.40 gpt gold over 4.8 meters emphasizes the potential for deeper mineralized zones beyond previous expectations.

Investors should recognize that these results demonstrate both the continuity of high-grade gold mineralization and the effectiveness of the company's drilling strategy. The Royal Shear trend appears to be growing in importance, with a reported 66% success rate of significant intersections in the recent drilling campaign. This is bolstered by the fact that twelve of eighteen completed holes returned notable mineralization, illustrating strong mineral continuity and reducing investment risk.

Endurance’s strategic plans include further metallurgical testing and resource modeling, which could enhance investment attractiveness by validating potential recoveries and project economics. Additionally, the ongoing activities of geological mapping and soil sampling could potentially lead to further discoveries, which would likely bolster the company's resource base and market valuation.

Given current market dynamics and the strength of these findings, investors might see this as an opportune moment to consider acquiring shares in Endurance Gold Corporation. The company’s proactive exploration and promising results could lead to upward price momentum as further assay results are anticipated. Monitoring the ongoing drill results and geological developments should be pivotal for investors seeking to capitalize on opportunities in the junior gold sector.

Vancouver, British Columbia--(Newsfile Corp. - October 6, 2025) - Endurance Gold Corporation (TSXV: EDG) (OTCQB: ENDGF) (FSE: 3EG) (the "Company") is pleased to announce assay results from three (3) additional drill holes from the Crown "Gap" Zone and one hole from the Imperial Zone at its 100%-owned Reliance Gold Project. All four (4) drill holes intersected gold mineralization hosted in the prime Royal Shear contact target, and one of the holes further tested a mineralized ultramafic-chert contact target in the footwall sequence, initially discovered and reported in hole DDH25-115. Highlights include:

  • Drill hole DDH25-117 returned 5.13 grams per tonne ("gpt") gold & 0.75% antimony ("Sb") over 19.8 metres ("m"), including 7.70 gpt gold & 1.07% Sb over 9.2 m. This hole successfully intersected the mineralized Royal Shear structure at a downhole depth of 164.8 m within the Imperial Zone, and was drilled with large diameter HQ core to collect mineralized material for the ongoing metallurgical test work program.
  • The previously undrilled Crown "Gap" Zone continues to grow with additional mineralized intersections returned from widely spaced drill holes. All three drill holes intersected mineralization at the Royal Shear contact.
    • Drill hole DDH25-119 intersected the Royal Shear contact at a downhole depth of 71.9 m. The hole returned 1.89 gpt gold over 0.6 m associated with an unmineralized feldspar dyke within the structural target host area. In this area, most of the mineralized zone target is interpreted to have been replaced by the feldspar dyke intrusive.
    • Drill hole DDH25-120 was a shallower angled hole drilled from the same pad and intersected the Royal Shear 50 m up-dip from DDH25-119 with 1.81 gpt gold over 7.0 m starting at a downhole depth of 55.7 m. This is the first intersection of near-surface mineralization returned from the Crown Zone.
  • Drill hole DDH25-121 returned two mineralized intervals. The hole returned 10.15 gpt gold over 1.5 m from a mineralized quartz-carbonate vein at the Royal Shear contact. This intercept represents a 85 m step-out from the nearest drillhole DDH24-103 that returned 7.61 gpt gold over 5.7 m also from the Royal Shear.
    • Drill hole DDH25-121 was drilled further into the footwall rocks to test a mineralized ultramafic-chert contact recently discovered in hole DDH25-115. This hole successfully intersected the contact target assaying 5.40 gpt gold over 4.8 m, including 12.0 gpt gold over 1.0 m. This new intercept is a 60 m step-out from hole DDH25-115 with 6.60 gpt gold over 2.4 m. The mineralized ultramafic-chert structural contact may represent a new stacked deeper zone related to the Lower Imperial structure intersected in DDH24-106 (4.47 gpt gold over 15.3 m, including 7.18 gpt gold over 8.3 m).

"Testing of the Crown Gap is now delivering a high success rate of encouraging drill intersections. The wide-spaced drilling success statistics demonstrate potential for mineralized continuity along the 1.5 kilometre Royal Shear trend from the Imperial to Upper Eagle Zones," stated Robert T. Boyd, President & CEO of the Company. "The association of ultramafic-associated gold mineralization makes the Crown Area unique along this trend."

Twelve (12) of eighteen (18) drill holes completed to date from the "Crown Gap" have returned significant gold and antimony mineralization. In addition to hosting mineralization along the Royal Shear structure, Crown Zone holes have consistently intersected narrower high-grade quartz-carbonate veins that have occasionally exhibited visible gold (such as in DDH23-078, DDH24-093 and DDH24-103).

The 2025 diamond drilling program has twenty (20) holes completed to date for a total of 6,438 m drilled. Assay results are pending for five (5) completed holes. The drilling rig is currently testing at 70 m step-out of the Lower Crown discovery hole DDH24-103. The current drilled hole will also test deeper into the footwall volcanic package to evaluate the interpreted extension of the ultramafic-chert structural contact intersected in holes DDH25-115 and DDH25-121.

All drill assay results are reported as core length intervals. True composite widths are estimated at 90% to 100% of core length. Highlighted intervals are reported in Table 1 below and the 2025 completed drill holes are shown on the plan map in Figure 1 and the Royal Shear inclined longitudinal section in Figure 2.

In other ongoing activities, mineral resource modeling is in progress and metallurgical testwork is in progress at the Blue Coast Research laboratory. Prospecting, geological mapping and soil sampling have continued through September on the eastern Olympic structures, and the southeast extension of the Royal Shear Trend. Over 1,500 soil samples and 150 rock samples have been collected to date.

Endurance Gold Corporation is a company focused on the acquisition, exploration and development of highly prospective North American mineral properties.
