Upside Gold Compilation Reveals Expanded Mineralization Potential at Kena Property

Upside Gold Corp. has completed a comprehensive compilation of historic exploration data at its Kena Gold-Copper Property in southeastern British Columbia, revealing a mineralized system that extends significantly beyond previously defined boundaries. The work, which integrated geological, geochemical, and geophysical data from exploration conducted since 1974, has resulted in an updated digital 3D exploration model that highlights expansion potential across the 10,115-hectare property.

The compilation indicates the mineralized trend extends at least seven kilometers along strike, beyond the historic mineral resource estimate of 2.77 million inferred ounces and 0.561 million indicated ounces of gold. Dr. Trevor Boyd, Vice President of Exploration for Upside Gold, stated that integrating decades of exploration data into a modern 3D model is helping identify areas where mineralization may extend beyond the historic resource and focus 2026 drilling on the most promising expansion targets. The company's February 3, 2026 news release provides additional context on the geological structures identified through this work.

Analysis of the property's drillhole database, containing 24,200 core samples, revealed that while historic drilling primarily recorded gold results, over 90% of samples included multi-element analytical data. The compilation systematically extracted copper and silver results from digital and analog analytical certificates, adding these to the master database. This revealed copper values reaching up to 71,800 ppm, with more than 2,900 samples exceeding 500 ppm Cu, and silver values reaching up to 145 ppm, with over 2,650 samples exceeding 1 ppm Ag. These results occur within a database containing 6,300 samples grading greater than 0.25 g/t Au, suggesting potential for significant additional metal value.

The integration of mapped geology with geophysical survey results supports that mineralization is structurally controlled by the Kena Deformation Zone, a steeply dipping, southeast-trending hydrothermally altered fault zone marking the contact between the Silver King Porphyry intrusive and Elsie Group intermediate volcanic rocks. This structure exhibits a low magnetic signature traceable for at least 11 kilometers along strike, as detailed in the company's technical documentation. Induced polarization surveys identify zones of high chargeability and low resistivity supporting disseminated pyrite-hosted mineralization extending beyond the known deposit.

Historic drilling outside the defined mineral resource has returned wide intervals of mineralization, including 117 meters of 0.22% Cu and 0.14 g/t Au, 88.69 meters of 0.13% Cu and 0.21 g/t Au, and 210 meters of 0.17% Cu and 0.13 g/t Au within the Kena Copper Zone. Similar results from the adjacent South Gold Zone include 90 meters of 0.9 g/t Au and 115 meters of 0.67 g/t Au with 0.05% Cu. The addition of historic soil survey data to the exploration model shows copper and gold geochemical anomalies spatially associated with favorable geophysical signatures, supporting geological interpretations of mineralization extending southwestward at depth beyond historic resource boundaries.

The compilation supports the presence of major surface to near-surface copper-gold porphyry bodies northeast and southeast of the known deposit that require detailed diamond drilling. Most priority drill targets for 2026 will focus on testing along strike to the southeast within the Kena Copper Zone, with the goal of defining a second major mineralized zone on the property. The work also indicates the mineralized system extends across much of the southern half of the property, which has never undergone diamond drilling or detailed exploration. The Kootenay region of southeastern British Columbia has been largely overlooked for gold and copper exploration historically, offering opportunities for new discoveries and development of known prospects into viable mineralized bodies.
