Goldshore Commences 21,000 Meter Grade Control Drill Program

VANCOUVER, B.C., June 30, 2025: Goldshore Resources Inc. (TSXV: GSHR / OTCQB:

GSHRF / FWB: 8X00) (“Goldshore” or the “ Company”) is pleased to announce the

commencement of the 21,000-meter grade control drill program at the Moss Gold Project, located

in Ontario, Canada (the “Moss Gold Project”).

This close-spaced drill program aims to define the optimal drill spacing for upgrading Inferred

Mineral Resources before the Feasibility Study. It will improve the definition of gold mineralization

continuity through detailed variography, aiding resource modelling and classification. The

program will also supply samples for feasibility-level metallurgical testing.

Michael Henrichsen, CEO and Director of Goldshore, commented, "We're pleased to kick off our

grade control drill program, a key component of our use of proceeds from our recent ly closed

financing. This program is critical for the development of the Moss project, defining the infill drill

spacing requirements as we look towards advancing the project towards a Feasibility study on

the back of our upcoming PEA in Q4.”
