Banyan Gold Files Technical Report for AurMac Project, Yukon, Canada

Banyan Gold Corp. announced the filing of a NI 43-101 Technical Report supporting an updated Mineral Resource Estimate (MRE) for its flagship AurMac Project in the Yukon Territory, effective May 15, 2026. The updated MRE reports a combined Indicated Resource of 3.64 million oz Au (167.3 Mt at 0.68 g/t) and an Inferred Resource of 4.98 million oz Au (267.2 Mt at 0.58 g/t).

This filing serves as a procedural follow-up to the May 19, 2026 MRE update, which already disclosed these figures, with the technical report formalizing the geological and economic assumptions used in the estimate. Technical parameters include a 0.30 g/t Au cut-off grade, a $3,500/oz gold price assumption, 90% gold recovery, and a 45° pit slope optimized via the Lerchs-Grossman algorithm.

The release also provides updated MRE figures for the Hyland Gold Project (Indicated: 337 Koz Au, 2.63 Moz Ag) and outlines the exploration status of the 100%-owned Nitra Gold Project. The Qualified Person for the report is Marc Jutras, P.Eng., M.A.Sc., Principal at Ginto Consulting Inc.

Banyan Gold Corp. (BYN) released a routine regulatory filing confirming previously disclosed resource data. The market had already absorbed the Mineral Resource Estimate (MRE) update on May 19, 2026, when the stock traded in the $1.35-$1.40 range. The filing satisfies NI 43-101 compliance requirements for public disclosure and contains no new quantitative or qualitative information that alters the investment thesis or valuation model.

The announcement is expected and incremental, validating the company's exploration progress without providing a new catalyst for immediate price appreciation. The $3,500/oz gold price assumption in the pit optimization is notably higher than the $2,050/oz used in the June 2025 MRE, reflecting a more bullish macro backdrop. However, this is a standard modeling update and does not change the underlying geology or drilling results.

Banyan Gold Corp. is a Yukon-based exploration and development company focused on building a generation-scale gold and silver operation. Its flagship AurMac Project is located in the Mayo Mining District and consists of two primary deposits: Airstrip and Powerline. The deposits feature high-grade skarn-style gold mineralization and Keno-style silver veins. The company has successfully converted waste blocks into high-grade ore through targeted drilling, expanding the resource envelope.

Banyan controls a contiguous 720 sq km land package, with over 95% remaining untested by drilling. This provides significant greenfields exploration upside, particularly at the Nitra project and the newly acquired Generic Gold properties in the Tintina Gold Belt. The project benefits from year-round road access, grid-connected power, and robust communications, reducing future development costs.
