Upside Gold Reports Initial Diamond Drilling Results from Kena Gold-Copper Property

Upside Gold Corp. has released a preliminary report on its initial diamond drilling program for the Kena Gold-Copper Property in southeastern British Columbia, with results from drill core assays completed in fall 2025. The program intersected multiple wide zones of gold mineralization consistent with the Kena Historic Resource grades, including a notable intersection of 178 metres starting from 15 metres depth grading 0.36 g/t Au, 1.8 g/t Ag, and 534 ppm Cu. This initial phase comprised 1,002 metres in three diamond drill holes designed to test the northeast margin of the Kena lode gold zone, encountering broad zones of near-surface significant gold mineralization with elevated copper and silver values, indicating local lateral expansion of the mineralized zone.

The drilling demonstrates the width and continuity of gold mineralization along the northeastern margin, with grades comparable to the Kena Historic Resource. The program was paused in November due to snow conditions and is expected to resume in June. Future drilling will continue to test targets to the northeast, as well as additional priority targets to the southwest down dip and southeast along strike, extending beyond the boundaries of the Kena Historic Resource. The three drillholes are shown on a map available at https://www.upsidegoldcorp.com/kena-map, with significant intersections summarized in a table at https://www.upsidegoldcorp.com/kena-table. The true widths of the intersections remain unknown at this stage.

Quality assurance and quality control procedures were rigorously followed during the sampling process. Collected 1-2 metre drill core samples were shipped by bonded carrier and submitted to ALS Canada Ltd laboratories in Kamloops and North Vancouver, B.C. ALS Canada Ltd. is an independent accredited testing laboratory assessed by the Standards Council of Canada and conforming to ISO/IEC 17025:2017 requirements. The Qualified Person inserted blind Au, Ag, and Cu accredited analytical standards and quartz blanks with the submitted batch. Rock sample analyses included gold and 34 multi-element inductively coupled plasma - atomic emission spectroscopy analysis by four acid digestion, following sample weighing, log in, and crushing with screening to -75 microns. ALS completed a standard package of internal laboratory QA/QC, including standards, blanks, and duplicates.

The technical information in this release has been reviewed and approved by Trevor Boyd, P.Geo., Vice President of Exploration for Upside Gold Corp. and a Qualified Person under NI 43-101 standards. The Kena Project hosts a historical gold resource comprising an Indicated Mineral Resource of 32,146,000 tonnes at 0.544 g/t Au for 0.561 million ounces of gold, and an Inferred Mineral Resource of 177,507,000 tonnes at 0.486 g/t Au for 2.77 million ounces of gold, as detailed in the technical report entitled "NI 43-101 Resource Estimate for the Kena and Daylight Properties" prepared by Sue Bird, P.Eng. of Moose Mountain Technical Services and filed on SEDAR. A Qualified Person has not done sufficient work to classify the historical estimate as current mineral resources, and Upside Gold is not treating it as such; the historical estimate is provided for information purposes only and should not be relied upon, with additional drilling required to upgrade it to current mineral resource status.
