Vancouver, British Columbia--(Newsfile Corp. - June 2, 2025) - Goldshore Resources Inc. (TSXV: GSHR) (OTCQB: GSHRF) (FSE: 8X00) ("Goldshore" or the "Company" or the "Company") is pleased to announce that it has entered into an agreement with Stifel Nicolaus Canada Inc. (the "Lead Underwriter") as lead underwriter and sole bookrunner, and a syndicate of underwriters to be formed (together, the "Underwriters") pursuant to which the Company has launched a "bought deal" private placement for aggregate gross proceeds of $25,000,000 (the "Offering") of:

1. 22,727,272 Charity flow-through shares (the "CFT Shares") at a price of $0.44 per CFT Share for total gross proceeds of $10,000,000;

2. 32,258,064 Hard dollar common shares (the "Common Shares") at a price of $0.31 per Common Share for total gross proceeds of $10,000,000; and

3. 13,157,894 Flow-through common shares (the "FT Shares" and together with the Common Shares and CFT Shares, the "Offered Shares"), at a price of $0.38 per FT Share for total gross proceeds of $5,000,000.

The FT Shares and CFT Shares will qualify as "flow-through shares" within the meaning of the Income Tax Act (Canada) (the "Act")

Gross proceeds from the sale of CFT Shares and FT Shares will be used to incur eligible Canadian exploration expenses and flow-through mining expenditures, as defined in the Act ("Qualifying Expenditures") related to the Company's Moss Gold Project in Ontario, on or before December 31, 2026, and to renounce all the Qualifying Expenditures in favour of the purchasers of the FT Shares and the CFT Shares effective December 31, 2025. Eventus Capital Corp. is an advisor to the Company.

Specifically, the Company intends to use the proceeds from the FT and CFT financings for the following activities:

• 21,000m of tight spaced "grade control" drilling to define drill spacing for the infill MRE conversion drill program and provide sample for feasibility level metallurgical test work
• 7,500m scout drilling to test district targets generated by the winter drill program
• An update to the Mineral Resource Estimate and additional test work to support the ongoing PEA
• Ongoing environmental baseline costs
• Ongoing community engagement programs
• Additional generative exploration, including bedrock geochemical samples plus outcrop stripping for mapping and sampling
• Field overhead costs

Michael Henrichsen, CEO of Goldshore commented, "The gross proceeds from the FT and CFT Share sale will be used to advance the Moss Gold Deposit through a critical phase of development, positioning the Company for the release of a Preliminary Economic Assessment (PEA) from G-Mining Services in Q4 of this year, and ultimately driving further de-risking and development activities thereafter."

Subject to compliance with applicable regulatory requirements, the CFT Shares and the Common Shares will be offered to purchasers resident in all Provinces of Canada (excluding Quebec) pursuant to the listed issuer financing exemption under Part 5A (the "Listed Issuer Financing Exemption") of National Instrument 45-106 – Prospectus Exemptions ("NI 45-106").
