Upside Gold Corp. Strengthens Kena Gold-Copper Property with Acquisition Agreement

CALGARY, Alberta — May 13, 2026 — Leads & Copy —

Upside Gold Corp. has signed a Claims Acquisition Agreement to acquire 100% interest in seven mineral claims totaling approximately 273 hectares on the northwest side of the Company’s Kena Gold-Copper Property in southeastern British Columbia, according to a press release issued May 13, 2026.

The agreement, further to its news release dated April, 27th, 2026, was made with a local prospector.

Sophy Cesar, CEO and Director of Upside Gold, stated that finalizing this acquisition is an important step in strengthening the continuity of the Kena Project. Cesar added that the historical high-grade production associated with these claims complements the company's broader district-scale exploration strategy and adds additional upside potential as Upside Gold continues advancing the Kena project.

The claims cover historically mineralized areas and strengthen the continuity of the Kena land package by connecting adjacent ground along a prospective mineralized trend.

Historically, the area formed part of the Venus-Juno Group, consisting of six reverted Crown grants that recorded past production of approximately 5,411 tonnes grading an average of 19.8 g/t gold and 17.7 g/t silver, with minor copper and lead credits, during the first half of the 20th century. This history of high-grade production supports the presence of mineralization within the broader district and reinforces the exploration potential of this largely under-explored portion of the Project.

Under the terms of the Agreement, Upside Gold will acquire a 100% interest in the claims for cash consideration, common shares of the Company, and a 0.5% net smelter returns royalty, subject to Canadian Securities Exchange approval. The Company retains the right to repurchase the NSR.

Upside Gold intends to integrate the newly acquired claims into its broader exploration strategy at the Kena, including ongoing evaluation of prospective gold, silver, and copper mineralization trends across the Project.

Trevor Boyd, P.Geo., Vice President, Exploration of the Company and a Qualified Person for the technical information under NI 43-101 standards, reviewed and approved the information in the press release.

The Kena Project hosts a historical gold resource comprising an Indicated Mineral Resource of 32,146,000 tonnes at an average grade of 0.544 g/t Au for 0.561 million ounces of gold, and an Inferred Mineral Resource of 177,507,000 tonnes at an average grade of 0.486 g/t Au for 2.77 million ounces of gold. The historical resource estimate is disclosed 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, dated May 3, 2021, and filed on SEDAR on behalf of West Mining Corp.

A Qualified Person, as defined by National Instrument 43-101, has not done sufficient work to classify the historical estimate as current mineral resources, and Upside Gold Corp. is not treating the historical estimate as current mineral resources. The historical estimate is provided for information purposes only and should not be relied upon. To upgrade the historical estimate as current mineral resource additional drilling needs to be completed. The historical estimate uses the categories set out in section 1.2 of the NI-43-101. The parameters and assumptions used are outlined in Bird 2021.
