Banyan Gold Corp. Announces Significant Mineral Resource Expansion at AurMac Project

Banyan Gold Corp. Has released a substantial update to its Mineral Resource Estimate (MRE) for the AurMac Gold Project, located in the Mayo Mining District of the Yukon, Canada. As of May 19, 2026, the company reported a marked increase in both indicated and inferred gold resources, reinforcing the project’s status as a rapidly growing asset in the Canadian mining sector.

Updated Mineral Resource Highlights

The 2026 MRE, prepared in accordance with National Instrument 43-101 (NI 43-101) standards, incorporates data from an additional 42,000 meters of drilling across 178 diamond drill holes. The updated figures reflect a significant expansion in the project’s overall gold inventory:

• Indicated Mineral Resources: 3.639 million ounces of gold at an average grade of 0.68 g/t (167.3 million tonnes).
• Inferred Mineral Resources: 4.985 million ounces of gold at an average grade of 0.58 g/t (267.2 million tonnes).

According to the company, these results represent a 60% increase in indicated contained ounces compared to the previous 2025 estimate, alongside an 8% improvement in the indicated grade. The updated model, developed by Marc Jutras of Ginto Consulting Inc., utilizes refined geological, lithological, and structural controls to better define mineralized zones within the Airstrip and Powerline deposits.

Project Infrastructure and Geological Context

The AurMac Project, covering approximately 720 square kilometers, benefits from its proximity to established infrastructure. The site is accessible via the main Yukon highway and is supported by a 3-phase powerline and existing power station infrastructure. The project is situated adjacent to the Keno Hill Silver District, currently operated by Hecla Mining Company.

The mineralization at AurMac is primarily intrusion-related. At the Powerline deposit, gold is associated with quartz veining influenced by rheological contrasts and silicification. At the Airstrip deposit, the mineralization is largely controlled by the contact between kalkhaltigen metasedimentary units and felsic dikes.

Strategic Outlook and Future Development

Banyan Gold Corp. President and CEO Tara Christie noted that the updated MRE serves as a critical foundation for the company’s upcoming Preliminary Economic Assessment (PEA), which is anticipated for the second half of 2026. The current results suggest that the deposits remain open in multiple directions, particularly at depth.

To continue the project’s momentum, Banyan has initiated a 70,000-meter drilling program for 2026, which is currently underway with up to six drill rigs operating on-site. Having completed over 21,000 meters of this program already, the company aims to further define and expand the resource boundaries.

Key Takeaways

• Resource Growth: Indicated resources reached 3.639 million ounces of gold, a 60% increase in contained ounces.
• Technical Validation: The estimate was prepared by an independent qualified person and follows CIM definition standards.
• Operational Focus: The company is pivoting toward a Preliminary Economic Assessment (PEA) scheduled for late 2026.
• Ongoing Exploration: A 70,000-meter drill program is active, with the deposits remaining open to further expansion.

A formal technical report detailing the methodologies and assumptions used in the 2026 MRE is expected to be filed on SEDAR+ within 45 days of the May 19 announcement. As Banyan Gold Corp. Continues to advance the AurMac Project, the focus remains on de-risking the asset and demonstrating the economic viability of this significant Yukon-based gold district.
