Yukon Metals Identifies New Exploration Target South of Birch Project

VANCOUVER, British Columbia, Sept. 15, 2026 /CourierPR/ -- Yukon Metals Corp., a copper-gold exploration company based in the Yukon Territory, has announced the identification of a new exploration target approximately 2 kilometers south of its Birch Project. The discovery was made through a recently completed induced polarization (IP) geophysical survey, which has expanded the company's exploration footprint into a broader intrusive system.

The IP survey, conducted by Aurora Geosciences Ltd., identified multiple chargeability anomalies in the southern area of the Birch Project. These anomalies coincide with a mapped intrusive body and elevated molybdenum-in-soil geochemistry. Select rock samples collected in the same area returned grades up to 16 grams per tonne (g/t) gold, 1,825 g/t silver, and 0.43% copper.

Jim Coates, CEO of Yukon Metals, commented, "The IP survey identified a large chargeability anomaly approximately two kilometers south of the skarn zone we had identified and drilled in 2025. The anomaly sits directly beneath the area where geochemistry, geology, and magnetics had already directed our attention, and it was tested by drilling hole 12 this season."

The company's exploration at Birch initially focused on the near-surface skarn mineralization, which provided clear and accessible drill targets. As work progressed, geological mapping, geochemistry, and geophysics have increasingly pointed to a broader intrusive-related mineralizing system extending beyond the known skarn. Skarn mineralization commonly develops where hydrothermal fluids associated with intrusive systems react with favorable host rocks, particularly carbonate-rich units such as limestone and marble.

At Birch, the relationship between the known skarn mineralization and the broader intrusive footprint is an important part of the evolving exploration model. Approximately 2 kilometers south of the drilled skarn area, previous exploration identified a coincident combination of elevated molybdenum-in-soil geochemistry, anomalous gold-silver-copper surface samples, mapped intrusive rock, and a magnetic high corresponding with a low potassium/thorium ratio zone in the radiometric data.

The 2026 IP survey was designed to add subsurface information to this developing exploration model and to test for chargeable features beneath the intrusive target. A total of 12.7 line-kilometers of 2D IP surveying was completed at Birch across four principal north-south survey lines and an east-west tie line. The principal lines were spaced approximately 300 meters apart.

Induced polarization and electrical resistivity are measured together in the same survey by passing an electrical current through the ground and recording how the rock responds. Resistivity reflects how readily current flows through the rock, and can distinguish between rock types, alteration, and structures; chargeability, the IP response, measures how briefly the ground holds an electrical charge after the current is switched off, a property that is generally elevated where disseminated sulphide minerals are present.

Granodiorite intrusions and marble/limestone act like electrical insulators that resist current flow and show up as high-resistivity bodies, while schist is lower resistivity. The sulfide-bearing zones, such as skarn with pyrrhotite and chalcopyrite, and porphyry potassic zones hold an electrical charge that creates chargeability anomalies. Because sulphides are commonly associated with the metals of interest in porphyry and skarn systems, chargeability anomalies are used to identify prospective zones for drilling.

The 2D inversion sections identified chargeability responses across the survey grid. At the north end of the grid, a chargeability anomaly is observed across multiple survey lines. In the southern portion of the grid, a separate chargeability anomaly is present to varying degrees on all four principal survey lines at approximately 400 meters below surface. An increased chargeability response is also observed on the east-west tie line, although at lower amplitude than on the principal lines.

Together, the surface geochemistry, geology, magnetic response, and new IP data provide multiple independent datasets for evaluating the broader mineralizing system south of the known skarn. One of the identified IP targets was tested during the 2026 drill program, with results pending.

Yukon Metals is continuing to integrate the Birch IP results with geological mapping, soil and rock geochemistry, magnetic data, and drilling. Follow-up mapping and prospecting in August 2026 refined the southern intrusive contact and identified molybdenite and local copper-bearing mineralization within the granodiorite, with alteration and veining increasing slightly along its northern contact. Garnet-pyroxene skarn boulders were also identified near the intrusive contact, supporting continued evaluation of the area for skarn-style mineralization. Pending assay and hyperspectral results from this work will be incorporated with the geophysical data to refine priority areas for further mapping, sampling, IP, and future drill targeting.

The Birch Project, a 7,000-hectare copper-gold exploration property located in western Yukon, approximately 65 kilometers northeast of Burwash Landing, represents an emerging copper-gold exploration opportunity within Yukon Metals' broader Yukon portfolio. Exploration to date has outlined skarn-style copper-gold mineralization, while geological, geochemical, and geophysical work suggests the potential for additional epithermal and porphyry-style mineralized systems.

Building on the 2025 program, which included 1,685 meters of HQ diamond drilling in six holes and established a broad copper-gold skarn footprint at Birch, Yukon Metals' 2026 exploration program included approximately 2,600 meters of additional diamond drilling, 12.7 line-kilometers of IP surveying, and follow-up geological mapping and rock sampling across priority target areas.
