About Upside Gold Corp.

Upside Gold Corp. is a Canadian gold-copper exploration company that has entered into an option agreement to acquire a 100% interest in the Kena Gold-Copper Project, located in southeastern British Columbia, approximately 7 kilometres southwest of Nelson. The Kena Project consists of 207 mineral claims and 11 crown grants covering 10,578 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 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. Additional drilling and technical work will be required to verify the historical estimate as a current mineral resource . 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: US $2,000/oz. Au at a currency exchange rate of 0.77 US$ per $CDN; 99.95% payable Au; $4.30/oz Au offsite costs (refining, transport and insurance); a 3% NSR royalty; and uses an 88% metallurgical recovery for gold.

4. Pit slope angles are assumed at 45º.

5. The specific gravity of the deposit has been assigned as 2.8 based on sg measurements in the Kena deposit.
