June 19, 2023

Vancouver, British Columbia, June 19th, 2023: Great Republic Mining Corp. (the "Company" or "Great Republic") (CSE: GRM) is pleased to announce that it has signed with ALS GoldSpot Discoveries Ltd. (“ALS GoldSpot”) to provide a comprehensive helicopter assisted geochemical sampling and data interpretation program at the Porcher Island Vanadium-Ti-Au project.

The Porcher Island project encompasses extensive deposits of ultramafic complexes that have been intruded by gabbroic formations containing iron-titanium-vanadium (Fe-Ti-V) minerals in the form of concentrated titaniferous magnetite. Previous samples obtained from the gabbroic bodies indicate vanadium content ranging from 0.34% to 0.84% V2O5. Two of the gabbroic bodies identified on the surface have dimensions of approximately 5.3 kilometers by 0.8 kilometers and 4.0 kilometers by 0.6 kilometers. Initial surveys conducted on the Properties, focusing on stream sediments, revealed vanadium concentrations that rank among the highest 99th percentile in all of British Columbia's Regional Geochemistry Survey (RGS) databases.
