Yukon Metals Files NI 43-101 Technical Report for Birch Project, Highlighting Expanding Copper-Gold Opportunities in Canada's Yukon Territory

VANCOUVER, British Columbia – June 2026 – Yukon Metals Corp. has officially filed an independent National Instrument 43-101 (NI 43-101) technical report for its wholly owned Birch Project in southwestern Yukon, Canada. The filing marks an important milestone for the company as it validates and documents the results of the project's inaugural drilling campaign while reinforcing the exploration potential of one of Yukon Metals' most promising copper-gold assets.

Technical Report Filed Under Canadian Mining Standards

The newly filed report, titled "NI 43-101 Technical Report of Activities on The Birch Property, Southwest Yukon, Canada", carries an effective date of January 19, 2026. The document was prepared by an independent qualified professional in accordance with Canada's strict NI 43-101 disclosure standards, which govern the reporting of mineral exploration and mining projects.

The report supports previously disclosed exploration results released by Yukon Metals in late 2025 and contains no material changes from the information already provided to investors and stakeholders. According to the company, the report serves as an independent confirmation of the scientific and technical data gathered during exploration activities at the Birch Project.

First-Ever Diamond Drilling Program Delivers Encouraging Results

The 2025 exploration season represented a historic milestone for the Birch Project, as it marked the first diamond drilling campaign ever conducted on the property. The program was designed to investigate a substantial 1.4-kilometre-long copper and gold soil anomaly that had been identified through earlier exploration work.

Results from the drilling campaign confirmed that the soil anomaly is linked to a genuine copper-gold mineralized system. Exploration teams identified multiple stacked skarn horizons and confirmed mineralization across a footprint measuring approximately 750 metres in length. These findings significantly enhanced the project's exploration potential and demonstrated the presence of a large-scale mineralizing system.

The successful drilling campaign provides Yukon Metals with valuable geological information and establishes a strong foundation for future exploration programs aimed at expanding the known mineralized zones.

Birch Project Located in a Highly Prospective Mining Region

The Birch Project covers approximately 7,000 hectares in western Yukon and is situated roughly 65 kilometres northeast of Burwash Landing. The property is fully owned by Yukon Metals and is accessible primarily by helicopter, a common transportation method for exploration projects in remote northern Canada.

The project forms an important part of Yukon Metals' broader exploration portfolio and has emerged as one of the company's priority copper-gold targets. Multiple exploration zones have already been identified across the property, providing numerous opportunities for future discoveries.

Geological studies suggest that Birch may host several styles of mineralization, including skarn-hosted copper-gold deposits as well as potential epithermal and porphyry-related mineral systems. Such geological diversity increases the property's overall exploration upside and makes it an attractive target for continued investment and exploration activities.

Drilling Results Reveal Significant Gold and Copper Intersections

During the 2025 exploration season, Yukon Metals completed approximately 1,685 metres of HQ diamond drilling across six drill holes. The campaign successfully intersected multiple mineralized zones and delivered encouraging results for both gold and copper mineralization.

Notable Gold Intersections

One of the most significant results came from drill hole BR25-003, which intersected:

• 47.4 metres grading 0.43 grams per tonne (g/t) gold
• Including a high-grade interval of 1.0 metre grading 14.35 g/t gold

The high-grade gold interval represents one of the strongest gold results recorded on the property to date and demonstrates the potential for the discovery of higher-grade mineralized zones within the broader system.

Notable Copper Intersections

Another important result came from drill hole BR25-001, which returned:

• 21.2 metres grading 0.30% copper
• Mineralization occurring between 138.8 metres and 160.0 metres depth

These copper values confirm the presence of economically significant copper mineralization and support the interpretation that Birch hosts a large and active mineralizing system.

Additional Surface Discoveries Expand Exploration Potential

Beyond the drill-defined mineralized zones, Yukon Metals also reported promising surface exploration results approximately two kilometres south of the primary drilling area. Prospecting programs identified elevated concentrations of gold, silver, copper, and molybdenum associated with a large soil anomaly.

These discoveries are particularly significant because they indicate that the known mineralization may represent only a portion of a much larger mineralized district. The presence of additional target areas creates opportunities for future drilling campaigns aimed at expanding the project's resource potential.

Evidence Points Toward Multiple Mineralization Events

Geological interpretations from the drilling campaign suggest that Birch contains multiple stacked mineralized horizons formed during separate mineralization events. This complexity is often associated with large hydrothermal systems capable of generating substantial mineral deposits over extended geological periods.

The identification of both copper-rich and gold-rich zones strengthens the possibility that Birch may host a larger porphyry-related system at depth. Such systems are among the world's most important sources of copper, gold, and molybdenum.

Strategic Importance of the Birch Project

The Birch Project has rapidly evolved into one of Yukon Metals' flagship exploration assets. As global demand for copper continues to rise due to renewable energy infrastructure, electric vehicles, and industrial development, projects with strong copper potential are attracting increasing attention from investors and mining companies worldwide.

Gold also remains a critical commodity for both investment and industrial applications. The combination of copper and gold mineralization at Birch positions the project within two of the mining industry's most sought-after commodity sectors.
