JAPAN GOLD COMPLETES CSAMT/AMT GEOPHYSICAL SURVEY AT HAKURYU PROJECT TO REFINE DRILL TARGETING

Japan Gold Corp. has completed a 34-line-kilometre controlled-source audio magnetotelluric and natural source geophysical survey at its Hakuryu project in Hokkaido. Zonge Engineering and Research Organization (Aust) Pty. Ltd. was contracted to perform the ground-based survey.

Utilizing advanced electrical techniques, the survey has produced high-resolution images of resistivity contrasts of the subsurface geology. The data will help refine drill hole locations and support more precise exploration targeting in the next drilling campaign. The survey results are currently under review.

The next stage of drill targeting will build on the encouraging 2025 drill results, including drill hole DDH-HAK-001 (refer to news release dated July 9, 2025), which returned 24.10 grams per tonne gold over 0.60 metre, reinforcing the potential for high-grade mineralization at the Hakuryu project.

Highlights of the Hakuryu project:

• The Hakuryu project is located at the southern end of the 16-kilometre-long Konomai goldfield. The northern and central parts of the Konomai vein field were developed and mined by Sumitomo Metal Mining Co. Ltd. between 1915 and 1973 producing 2.35 million ounces of gold at an average grade of 6.4 grams per tonne.
• Drilling at Hakuryu commenced in April, 2025. The first phase of drilling comprised three holes from two drilling sites, with a total drilling length of 565.7 metres, designed to test the Hakuryu No. 3 vein. Assay highlights include:
  • 16.15 g/t Au over 0.60 metre (drill hole: DDH-HAK-001) from 103.8 metres (a reassay of this interval yielded 24.10 g/t over 0.60 metre from 103.8 metres);
  • 1.52 g/t Au over 3.30 metres (drill hole: DDH-HAK-002) from 164.2 metres.
• Assay results indicate that two drill holes (DDH-HAK-001 and DDH-HAK-002) intersected anomalous gold mineralization. The mineralization is associated with a zone of hydrothermal brecciation, which sits on the hangingwall side of a well-developed fault zone. The mineralization in both holes is associated with the same structural zone, indicating continuity of the mineral intersection over 145 metres of strike. The largely untested structural zone is part of a much more extensive corridor of alteration that extends for over five kilometres.
