JAPAN GOLD IDENTIFIES MULTIPLE GEOPHYSICAL ANOMALIES AT HAKURYU PROJECT

Japan Gold Corp. has completed its review of the controlled-source audio magnetotellurics and natural source (AMT) geophysical survey results from the December, 2025, program at the Hakuryu project in Hokkaido, Japan.

The survey results identified multiple resistivity anomalies that correlate with previously mapped surface alteration zones and projected vein trends. These resistivity anomalies extend across multiple survey lines, suggesting continuity along strike within the proposed target areas. The confirmation of multiple anomalies at depth along the approximately five-kilometre prospective strike length supports proceeding with drill pad preparation in advance of a planned drilling campaign to further evaluate the project area.

The next phase of drilling is being designed to follow up on the anomalies identified in the recent geophysical survey, as well as the 2025 drill hole DDH-HAK-001 (refer to news release dated July 9, 2025), which intersected 16.15 grams per tonne gold over 0.60 metre from 103.8 metres downhole (a reassay of the same interval returned 24.10 g/t gold over 0.60 metre).

The Hakuryu project is located at the southern end of the 16-kilometre-long Konomai goldfield. The northern and central portions of the Konomai vein field were historically developed and mined by Sumitomo Metal Mining Co. Ltd. between 1915 and 1973, reportedly producing approximately 2.35 million ounces of gold at an average grade of 6.4 g/t.
