Upside Gold Corp. has released preliminary exploration results from its Kena Gold-Copper Property in southeastern British Columbia, confirming multiple high-grade gold-silver-copper showings beyond existing historic resource boundaries and identifying 22 priority diamond drill targets. The results from the company's July 2025 surface rock geochemical sampling program support the existence of a large, multi-zone mineralized system with strong expansion potential along strike and at depth.
The exploration program, which collected 141 rock geochemical samples, returned values up to 26.1 grams per tonne gold, 179 grams per tonne silver, and 1.68 percent copper. These findings confirm that gold and copper mineralization extends east and south of the historic Kena gold body, aligned with major structures and coincident geochemical and geophysical anomalies. The drill-ready targets have been defined both inside and outside the historic resource area, including several zones with minimal or no prior drilling.
Three areas beyond the Kena lode gold body boundaries are considered particularly promising for follow-up exploration. The Lower and Upper Euphrates Au-Ag showings, which report historic production of 307 tonnes at 46.9 g/t Au and 249 g/t Ag, have become accessible following new logging road construction. Nine grab samples from this area averaged 8.61 g/t Au and 31.6 g/t Ag, with no known drilling previously conducted there.
The Cat, Shaft, Dighem, and Princess Cu-Au-Ag showings are aligned along the east side of the Kena Gold lode body over a 1,200-meter strike length, associated with a strong induced polarization chargeability anomaly measuring 1.8 by 0.6 kilometers with coincident copper soil anomalies. Rock samples from these showings returned up to 1.68 percent copper, 5.41 g/t gold, and 18 g/t silver, supporting historic reports of multiple high-grade occurrences. Historically, only five reconnaissance drill holes have been completed across this entire area.
The Kena Copper Zone and adjoining South Gold Zone extend three kilometers southeast from the Kena Gold lode body, covering extensions of similar geology associated with strong IP chargeability and broad copper and gold soil anomalies. Historic drilling reports multiple wide intersections of good copper and gold values starting at or near surface, including 117 meters of 0.22 percent copper and 0.14 g/t gold, and 90 meters of 0.9 g/t gold in the South Gold Zone. Surface rock samples collected during the 2025 program returned up to 1.31 g/t gold, supporting the potential for these zones to host significant volumes of mineralized material.
The property's gold mineralization is predominantly controlled by the northwest-trending Kena Deformation Zone, situated within and between the Silver King Porphyry intrusive and Elsie Volcanic rocks, characterized by a strong low magnetic intensity signature. The technical information has been reviewed and approved by Trevor Boyd, P.Geo., Vice-President of Exploration and a Qualified Person under NI 43-101 standards.

The historical resource estimate for the property, disclosed in the technical report titled "NI 43-101 Resource Estimate for the Kena and Daylight Properties" by Sue Bird of Moose Mountain Technical Services and filed on SEDAR, reported an Indicated Mineral Resource of 32,146,000 tonnes at 0.544 g/t Au for 0.561 million ounces and an Inferred Mineral Resource of 177,507,000 tonnes at 0.486 g/t Au for 2.77 million ounces. The company emphasizes that this historical estimate should not be relied upon as current mineral resources.
The Kootenay region of southeastern British Columbia has historically been largely overlooked for gold and copper exploration, offering opportunities for both new discoveries and development of known historic prospects into potentially viable resource bodies. The results support the company's belief in the existence of a major gold-copper mineralized system that extends beyond currently defined boundaries and into the southern half of the property, an area that has not previously undergone diamond drilling or detailed exploration.
