Endurance Gold reports an Inaugural Mineral Resource Estimate at our 100% owned Reliance Gold (antimony) project with Inferred Mineral Resources of 19.6 Mt grading 2.30 gpt gold, for 1.45 Moz of contained gold. Highlights include: Near-Surface Inferred Mineral Resources of 15.6 Mt grading 2.23 gpt gold, for 1.12 Moz contained gold, and Underground Inferred Mineral Resources of 4.0 Mt grading 2.58 gpt gold for 0.33 Moz contained gold, with the underground resources open to expansion along strike and to depth. What's next? Infill drilling within the constraining pit to expand and upgrade the near-surface Inferred MRE with deeper, step-out drilling to expand the underground Inferred MRE. Additionally, we will be conducting ongoing metallurgy test work to focus on gold concentrate grade and recovery optimization and antimony recovery as initial test work indicates gold recovery to a high-grade marketable gold concentrate. Lastly, we will be commencing economic and engineering studies with the goal of completing a Preliminary Economic Assessment (“PEA”) on this Inferred MRE.

Exploration at our 100%-owned Reliance Gold-Antimony Project in British Columbia has been highly productive in 2026, with significant milestones achieved and several important catalysts anticipated through the fourth quarter. Inaugural Gold Resource: In January, we announced an Inferred Mineral Resource Estimate of 19.6 million tonnes grading 2.30 g/t gold, containing 1.45 million ounces of gold. Resource Expansion Potential: More than 10,000 metres of additional drilling has been completed in 2026, with several encouraging step-out intersections reported over the summer. Further assay results are anticipated this fall as laboratory backlogs clear, supporting the potential for future resource expansion. Eagle Offset Discovery Potential: Inaugural drilling at the Eagle Offset target, approximately 1 kilometre from the current resource, is progressing favourably. Observed alteration and mineralization associated with gold-bearing systems provide encouraging early indications, with assay results pending. Metallurgical Advancements: Ongoing metallurgical testwork on the existing resource is expected to provide important insights into gold recovery and processing characteristics, representing another key milestone as the project advances.

Diamond drilling and RC Drilling remain active though October at the Reliance Project BC. To date over 9,000 meters of diamond drilling has been completed in about 20 holes potentially expanding the size of the Mineral Resource Estimate. Furthermore, on the new Eagle Offset target, over 22 Reverse Circulation (RC) drill holes averaging about 70 m length each have been completed to date testing a strong, previously undrilled, geochemical and alteration system. Once the laboratory catches up, we expect a busy fourth quarter of gold and antimony results to be delivered to our shareholders.

Our fully funded 2026 drill program at the 100%‑owned Reliance Gold (antimony) project continues to gain momentum. As of mid‑September, the combined diamond and reverse‑circulation (RC) drilling campaign has completed over 9,000 metres in 22 diamond drill holes targeting the Eagle, Crown, and Imperial zones along the Royal Shear trend, with assay results still pending on 15 of those holes. Current company estimates indicate the 2026 diamond drill program will exceed 10,000 metres in the area of the existing Mineral Resource Estimate (MRE). In addition, as of Sunday, we have already completed 10 RC drill holes on the Eagle Offset target.

Endurance Gold announces that the 2026 Reverse Circulation (“RC”) drilling program has commenced at the Eagle Offset Target at our 100%-owned Reliance Gold Project. A minimum of 25 RC holes are planned at the Eagle Offset Target, with two drill access trails recently excavated across the previously undrilled soil anomaly. Our 2026 diamond drilling program is expanding the Mineral Resource Estimate at Reliance, while the RC program is targeting new near-surface gold discoveries that warrant follow-up diamond drilling and further expand the gold-antimony camp potential of Reliance. Diamond drilling also continues to advance, with 9,025 metres completed in 21 holes to date. The program is expected to exceed 10,000 metres, with assays currently pending from 14 completed holes.

As reported in August, Drill holes DDH26-135 and DDH26-136 have intersected the Eagle Zone "Feeder Structure" below the current Mineral Resource Estimate (MRE) at our 100% owned Reliance Gold (antimony) project, representing a down-dip expansion of mineralization beneath the existing 1.45 million ounce Inferred MRE. Highlight intersection in DDH26-135 includes 9.27 gpt Gold over 6.1 Metres. This structure was previously intersected by DDH22-023, which returned 9.57 gpt gold over 1.6 metres. These latest results continue to demonstrate the depth potential of the mineralizing system along the Royal Shear trend. Stay tuned as we deliver further results.

Assay results from our 100% owned Reliance Gold (antimony) project continue to deliver. At 254.1 metres downhole on the Eagle Zone, drill hole DDH26-135 returned 9.27 gpt gold and 0.36% antimony over 6.1 metres, including a higher grade interval of 19.40 gpt gold and 0.23% antimony over 1.0 metre. This high-grade intersection represents a 100 metre down-dip extension external to our current inaugural Inferred Mineral Resource Estimate (MRE) of 1.45 million ounces of gold, highlighting the growth potential that remains along the Royal Shear trend.

We recently announced the second batch of 2026 assays from our 100%-owned Reliance Gold (antimony) Project. As of the end of July, our fully funded two-diamond-drill-rig program has completed 7,200 m across 18 holes at the Eagle, Crown, and Imperial Zones along the Royal Shear Trend. Originally planned for a minimum of 8,000 m, the 2026 program is now expected to exceed 10,000 m in the area of the Mineral Resource Estimate (MRE). Drilling continues, with additional holes and metres being added to the MRE expansion program to follow up on mineralization intersected this year along the margins of the existing resource.

In addition to active Diamond Drilling at our 100% owned Reliance Gold (antimony) Project in Southern BC other activity includes ongoing Metallurgical and Mineralogical studies. Thus far, Stibnite is the primary observed antimony mineral at Reliance and therefore ongoing studies at Reliance have an objective of creating a separate stibnite concentrate available to the critical minerals market. These same studies will also be evaluating processing alternatives for the optimal Gold recovery to a Concentrate. We can use the conclusions from these studies to evaluate incorporating antimony credits in the future updated Mineral Resource Estimate (MRE). The current MRE at Reliance is entirely gold-only and includes an open-pit constrained inferred mineral resource estimate of 1.45 million ounces of gold grading 2.3 grams per tonne gold (see MRE Disclaimer on company website).

Endurance Gold announces the second batch of 2026 assay results from our 100%-owned Reliance Gold Project. Highlights include: • 9.27 gpt gold and 0.36% antimony over 6.1 m, including 19.40 gpt gold and 0.23% antimony over 1.0 m This high-grade intersection represents a 100 m down-dip extension outside the current Mineral Resource Estimate at the Eagle Zone Feeder Structure, highlighting continued growth potential at Reliance. • 4.33 gpt gold and 0.03% antimony over 7.7 m, including 9.53 gpt gold and 0.07% antimony over 2.9 m Drilling remains active, with an additional eleven (11) diamond drill holes now completed. Ten of these holes are targeting the Crown and Imperial Zones with the objective of expanding the current Mineral Resource Estimate. Read the full press release: endurancegold.com/news-relea…

Two active drills now exceed 6.2 km of additional drilling in 2026 at the location of our inaugural resource at our 100% Reliance Gold (antimony) project. Objectives of the MRE drilling are to: Expand the current inferred Mineral Resource Estimate (MRE) with step-out drilling in undrilled sections of the Royal Shear. Ensure sufficient drill information to upgrade portions of the MRE from the Inferred to the Indicated Category. Collect structural data from the 2026 drill core to enhance the geological model. Use the additional 2026 drill information to determine optimum open pit versus underground constrained updates to the MRE

Two drills are turning and currently drilling on the 15th  diamond drill hole this year with about 5,200 meters drilled so far this season. Assay results are slow from the analytical lab but we are encouraged that geological observations indicate the gold system continues to grow as we step-out on the inaugural MRE announced in January 2026. Stay tuned for results as the summer progresses.

Drill road preparations are underway at the Eagle Offset target south of the Reliance MRE. Several strongly altered outcrops have now been observed in the area of the 1.3 km long Geochem anomaly announced on January 21st. Mapping and sampling is planned for July. The geological team is excited about this new target and we look forward to designing the Phase 2 drill testing program once mapping and sampling results are in-hand.

2026 Drilling at our Reliance Gold (antimony) project in BC will likely exceed the previously announced planned 8,000m of diamond drilling. Two drills have been active since early May with over 10 drill holes completed to date. The Phase 1 drilling is “stepping out” to increase the 1.45 million ounce Inferred resource and also upgrade Inferred to the Indicated category. The first 2026 drill hole result was announced in June with an excellent intersection of 11.01 gpt gold over 8.7m. A news packed 2026 awaits as further results are delivered - stay tuned!
