Endurance Expands Imperial and Lower Imperial Zones with 50 m Step Outs 5.89 gpt Gold and 0.19% Sb over 5.2 Metres & Multiple High-Grade Structures

Endurance Gold expands Reliance Project zones with high-grade gold-antimony drill results.

What the company is saying

Endurance Gold Corporation (TSXV:EDG, OTCQB:ENDGF, FSE:3EG) reports that six new diamond drill holes at its 100%-owned Reliance Gold Project in British Columbia have expanded both the Imperial and Lower Imperial Zones and uncovered multiple high-grade structures in the Royal Shear footwall. The company frames these results as evidence of significant growth potential, highlighting wide intersections and high-grade intervals such as 31.90 gpt gold and 0.30% antimony over 0.5 meters. President and CEO Robert T. Boyd states that the 2026 drilling has increased the size of key zones and identified new mineralized structures, supporting the opportunity to add mineralized volume. The tone is confident, emphasizing the ongoing nature of the drill program, pending Crown Zone assays, and further metallurgical test work. The company also references its January 2026 NI 43-101 Inferred Mineral Resource Estimate of 19.6 million tonnes at 2.30 gpt gold for 1.45 million ounces. Technical and scientific oversight is provided by Darren O'Brien, P.Geo., Vice President Exploration, who is named as the Qualified Person.

What the data suggests

The disclosed results show that all six reported drill holes intersected gold and antimony mineralization, with headline intervals such as 5.89 gpt gold and 0.19% Sb over 5.2 meters (DDH26-140), 2.24 gpt gold and 0.06% Sb over 16.2 meters (DDH26-137), and high-grade structures up to 31.90 gpt gold and 0.30% Sb over 0.5 meters (DDH26-137). True composite widths are estimated at 80% to 100% of core length. The company has completed over 10,200 meters of diamond drilling in 2026 across 25 holes at the Eagle, Crown, and Imperial Zones, bringing the total to over 42,000 meters in the MRE area. The Eagle Offset anomaly, measuring 1,300 by 500 meters, has seen 31 RC holes drilled and over 1,500 samples submitted for assay. Metallurgical test work is ongoing, with seven of ten flotation samples tested and gold assays pending. The technical disclosure is detailed, with specific grades, widths, and locations, but no financial, cost, or economic study data is provided. The evidence supports the company's narrative of expanding mineralized zones and discovering new high-grade structures, but the project remains at the exploration stage.

Analysis

The announcement provides detailed and specific technical results from ongoing exploration at the Reliance Gold Project, including precise assay intervals, drilling meters, and a compliant NI 43-101 resource estimate. The majority of claims are realised and supported by disclosed data, such as drill results and resource tonnage. Forward-looking statements are present but limited, mainly relating to pending assay results, ongoing metallurgical test work, and the project's perceived growth potential. The tone is positive but proportionate to the evidence, with no exaggerated language or unsupported claims about imminent production or financial returns. The capital intensity flag is set because significant drilling and sampling activity is disclosed, with benefits (if any) only realisable in the long term, typical for an exploration-stage company. There is no hype beyond standard exploration optimism, and the technical disclosure is credible and transparent.

Risk flags

• ●The project remains at the exploration stage, with no preliminary economic assessment, feasibility study, or development timeline disclosed. This means there is no demonstrated economic viability, and resource conversion to reserves is uncertain.
• ●Assay and metallurgical results are still pending for several zones, including the Crown Zone and Eagle Offset RC drilling. Delays or disappointing results in these areas could impact the perceived scale or quality of the project.
• ●The mineral resource estimate is classified as Inferred, which carries a high degree of uncertainty and cannot be assumed to be economically viable or convertible to reserves without further drilling and technical work.
• ●The company discloses that mineral resources may be materially affected by environmental, permitting, legal, title, taxation, sociopolitical, or market factors, any of which could delay or prevent project advancement.
• ●No financial data, cost estimates, or funding details are disclosed, leaving open questions about the company's ability to finance continued exploration and eventual development.

Bottom line

Endurance Gold's latest drill results at the Reliance Project in British Columbia confirm the expansion of both the Imperial and Lower Imperial Zones and reveal new high-grade gold-antimony structures, with intervals such as 31.90 gpt gold and 0.30% Sb over 0.5 meters. The company has now drilled over 42,000 meters in the resource area and continues to advance exploration with ongoing drilling and metallurgical studies. While the technical results are strong and support the narrative of a potentially scalable orogenic gold system, the project remains at a pre-economic, exploration stage with no disclosed development timeline or financial data. Investors should watch for upcoming assay results from the Crown Zone and metallurgical test work, as well as any future resource upgrades or economic studies. The most important takeaway is that while the technical results are promising, realization of value is contingent on successful resource conversion, economic viability, and project advancement beyond exploration.

Announcement summary

(TSXV:EDG) (OTCQB:ENDGF) (FSE:3EG) Endurance Gold Corporation reported assay results from six diamond drill holes at its 100%-owned Reliance Gold Project, British Columbia, expanding the Imperial and Lower Imperial Zones and identifying multiple high-grade structures in the footwall of the Royal Shear. The Reliance Gold Project is located 4 kilometres east of Gold Bridge, British Columbia, in the historic Bridge River Mining Camp. In January 2026, the company announced an inaugural Inferred Mineral Resource Estimate (MRE) of 19.6 million tonnes at an average grade of 2.30 grams per tonne gold, for 1.45 million ounces contained gold. All six reported holes intersected gold and antimony mineralization. DDH26-140 extended the Imperial Zone 50 meters northwest with 5.89 gpt gold and 0.19% Sb over 5.2 meters, including 8.54 gpt gold and 0.41% Sb over 2.0 meters. DDH26-137 extended the Lower Imperial Zone 55 meters southeast with 2.24 gpt gold and 0.06% Sb over 16.2 meters, including 11.75 gpt gold and 0.42% Sb over 0.6 meters. DDH26-140 also returned 6.41 gpt gold and 0.22% Sb over 1.0 meter. DDH26-130A returned 2.97 gpt gold and 0.03% Sb over 11.1 meters, including 6.40 gpt gold and 0.03% Sb over 1.9 meters. DDH26-134A returned 3.96 gpt gold and 1.92% Sb over 10.9 meters, including 9.71 gpt gold and 0.41% Sb over 2.0 meters. Five of the six holes intersected previously undefined high-grade structures, including 31.90 gpt gold and 0.30% Sb over 0.5 meters in DDH26-137, 17.10 gpt gold and 0.05% Sb over 2.0 meters in DDH26-140, and 8.55 gpt gold and 1.42% Sb over 2.0 meters in DDH26-144. Fourteen notable high-grade intercepts are summarized in Table 2. The company has now completed more than 10,200 meters in 25 diamond drill holes at the Eagle, Crown, and Imperial Zones, bringing the total to over 42,000 meters of diamond drilling in the MRE area. Drilling continues at the Crown Zone, with partial assay results being compiled. The Eagle Offset geochemical anomaly, measuring approximately 1,300 meters by 500 meters, was identified through prospecting and soil sampling in 2025. In September, 2 km of access trails were excavated, and 31 reverse-circulation holes were drilled, with over 1,500 RC samples submitted for laboratory assay analysis. Flotation test work and mineralogical studies are in progress at Blue Coast Research, with seven of ten samples tested and associated gold assays pending. The MRE was prepared by Ginto Consulting Ltd. in accordance with NI 43-101, effective January 8, 2026, and the technical report is available on SEDAR+ and the company website. Robert T. Boyd is President and CEO. Darren O'Brien, P.Geo., Vice President Exploration, is the Qualified Person for the release.
