Endurance Gold Corp. reached a key de-risking milestone with the release of an inaugural Inferred Mineral Resource Estimate (MRE) for its 100%-owned Reliance Gold Project in southwest British Columbia. The MRE outlines 19.6 Mt grading 2.30 g/t gold, containing 1.45 Moz of gold, establishing Reliance as a meaningful emerging gold asset within the historic Bridge River Mining Camp (see Table 1). The resource is notably weighted toward near-surface mineralization, with 1.12 Moz hosted in an open-pit constrained component totaling 15.6 Mt at 2.23 g/t gold, supporting potential development flexibility and favorable mining economics, see Figure 1. A further 0.33 Moz is defined in an underground inventory of 4.0 Mt at 2.58 g/t gold, providing higher-grade optionality. We view the project’s location as a competitive advantage, benefiting from existing road access, hydroelectric power, water, and a local skilled workforce. Importantly, mineralization remains open along strike and at depth, positioning the current 1.45 Moz resource as a solid foundation for future growth through continued drilling.
Investment HighlightsÂ
Resource quality and development profile Â
- High-grade maiden resource: 1.45 Moz Inferred at 2.30 g/t gold establishes a strong development baseline.Â
- Open-pit dominant inventory: 1.12 Moz near surface supports scalable pit development with existing infrastructure access.Â
Growth and expansion potential Â
- Underground upside: 0.33 Moz defined below pit shell, open at depth and along strike. Â
- Clear upgrade pathway: Infill and step-out drilling target resource expansion and conversion to IndicatedÂ
Exploration and district scale upsideÂ
- Strike length doubled: Royal Shear trend extended to 3.5 km with offset target, materially increasing discovery potential.Â
- Drill-ready pipeline: Multiple anomalies rivaling MRE footprint positioned for near-term drilling.Â
Technical and economic resilienceÂ
- Favorable metallurgy: Simple flotation flowsheet with 81–85% recoveries and cleaner circuit upside.Â
- Robust economics: Sensitivity analysis highlights strong grade–tonnage continuity under varying cut-off scenarios.Â
We are updating our fair market price for the Company to reflect the increase in confidence with the initial MRE at Reliance and our expectations for further resource growth and discovery. Our new target stands at $1.25 with room for further upside on gold price appreciation impacts.

Overall Risk Rating
Very High Risk:Â Venture-type companies or more established micro, small, mid or large-cap companies whose risk profile parameters and/or lack of liquidity warrant such a designation. These companies are only appropriate for investors who have a very high tolerance for risk and volatility and who can incur a temporary or permanent loss of a very significant portion of their investment capital.
High Risk:Â Typically, micro or small-cap companies which have an above-average investment risk relative to more established or mid to large-cap companies. These companies will generally not form part of the broad senior stock market indices and often will have less liquidity than more established mid and large-cap companies. These companies are only appropriate for investors who have a high tolerance for risk and volatility and who can incur a temporary or permanent loss of a significant portion of their investment capital.
Medium-High Risk:Â Typically, mid to large-cap companies have a medium to high investment risk. These companies will often form part of the broader senior stock market indices or sector-specific indices. These companies are only appropriate for investors who have a medium to high tolerance for risk and volatility and who are prepared to accept general stock market risk including the risk of a temporary or permanent loss of some of their investment capital
Moderate Risk:Â Large to very large cap companies with established earnings who have a track record of lower volatility when compared against the broad senior stock market indices. These companies are only appropriate for investors who have a medium tolerance for risk and volatility and who are prepared to accept general stock market risk including the risk of a temporary or permanent loss of some of their investment capital.
