UPSIDE GOLD ANNOUNCES FULLY PERMITTED DRILL PROGRAM AT THE KENA GOLD-COPPER PROJECT

Upside Gold Corp. has made plans for a fully permitted diamond drill program at its Kena gold-copper project in southeastern British Columbia, with drilling expected to commence in June, 2026.

Highlights of the 2026 drill program:

• Approximately 4,000 metres of diamond drilling planned;
• Drilling expected to commence in June, 2026;
• Program designed to support expansion of the existing historical gold resource;
• Targeting both gold and copper mineralization across multiple zones;
• Continued evaluation of the Kena copper-gold zone and broader district-scale mineralized system.

The planned program is designed to support resource expansion at Kena through a combination of stepout and target expansion drilling focused on near-resource mineralization and emerging gold-copper targets, including the Kena copper-gold zone.

The 2026 program follows approval of the company's multi-year area-based permit annual update by the B,C. Ministry of Mining and Critical Minerals, which authorizes additional drill sites and access trails as part of the continuing advancement of the project.

"We believe Kena represents a rare combination of scale and expansion potential in Southern British Columbia," stated Sophy Cesar, chief executive officer of Upside Gold. "This next phase of drilling is focused on growing and strengthening the existing resource footprint while continuing to demonstrate the broader gold-copper potential across the property. We are particularly encouraged by the emerging copper component of the system and the opportunity to continue advancing the Kena copper-gold zone alongside the established historical gold resource."

Dr. Trevor Boyd, vice-president, exploration, added: "The 2026 drill program is designed to systematically test extensions of known mineralization while also advancing several highly prospective gold-copper targets identified through compilation of historic drilling, geophysics, surface sampling and geological interpretation. We believe the Kena system remains significantly underexplored relative to its size and geological potential."

The information in this press release has been reviewed and approved by Dr. Boyd, PGeo, vice-president, exploration, of the company, 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 indicated mineral resource of 32,146,000 tonnes at an average grade of 0.544 gram per tonne gold 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 National Instrument 43-101. The assumptions used are outlined as follows:

1. Resources are reported using the 2014 Canadian Institute of Mining, Metallurgy and Petroleum 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 gold at a currency exchange rate of 77 U.S. cents per $1 (Canadian); 99.95 p;er cent payable Au; $4.30-per-ounce-gold off-site costs (refining, transport and insurance); a 3-per-cent net smelter return royalty; and 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 specific gravity measurements in the Kena deposit.
