UPSIDE GOLD REPORTS DRILLING UNDERWAY AT THE KENA GOLD-COPPER PROJECT AND RECEIVES MINES ACT PERMIT EXTENSION

Upside Gold Corp.'s 2026 drill program at the Kena gold-copper project in southeastern British Columbia has commenced, with crews and equipment mobilized and actively diamond drilling on site.

The company has also received an amendment to Mines Act permit MX-100000131, extending the current permit term to Oct. 31, 2026. The amendment provides continued authorization for the company's continuing exploration activities and supports execution of the 2026 drill program into the fall.

The fully financed program will focus on priority targets identified through the company's technical review, which integrated historical drilling, and geological, geochemical and geophysical data into a refined exploration model. The program is designed to evaluate extensions of known resource, test new target areas and support future mineralized zone growth.

Initial drilling is focused on testing extensions of known mineralization within and adjacent to the historical gold resource*, where the company believes there is strong potential to expand its size along strike and at depth. Additional drilling will also evaluate several high-priority regional targets identified through the company's recent compilation work.

"Our team has spent the past year building what we believe is one of the strongest technical foundations the Kena project has ever had," said Sophy Cesar, chief executive officer and director of Upside Gold. "With drills turning, we are moving from planning to execution. We have strengthened our treasury, expanded the property and refined our geological model. With the permit extension in place, we are focused on advancing the project through systematic exploration providing shareholders with updates as the program progresses."

The company expects to provide regular updates throughout the drill program, including significant assay results as they become available.

The information in this news release has been reviewed and approved by Trevor Boyd, PGeo, vice-president, exploration, of the company and a qualified person for the technical information under National Instrument 43-101 standards.

About Upside Gold Corp.

Upside Gold is a Canadian gold-copper exploration company that has entered into an option agreement to acquire a 100-per-cent interest in the Kena gold-copper project, located in southeastern British Columbia, approximately seven kilometres southwest of Nelson. The Kena project consists of 198 mineral claims covering 10,114.8 hectares, together with 11 Crown grants covering approximately 92 hectares.

The corporation is focused on advancing the Kena gold-copper project through systematic exploration and drilling programs.

The Kena project hosts a historical gold resource* comprising an originally filed indicated mineral resource of 32,146,000 tonnes at an average grade of 0.544 gram per tonne (g/t) gold (Au) for 561,000 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, PEng, 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 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 and are provided as follows:

1. Resources are reported using the 2014 CIM definition standards and were estimated using the 2019 CIM best practices guidelines.
2. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
3. The mineral resource has been confined by a "reasonable prospects of eventual economic extraction" pit using the following assumptions: $2,000 (U.S.) per ounce (oz) Au at a currency exchange rate of 77 U.S. cents per $1 (Canadian); 99.95 per cent payable Au; $4.30 per oz Au off-site costs (refining, transport and insurance); a 3-per-cent net smelter return (NSR) royalty; and uses a 88 per cent metallurgical recovery for gold.
4. Pit slope angles are assumed at 45 degrees.
5. The specific gravity of the deposit has been assigned as 2.8 based on sg measurements in the Kena deposit.
