JAPAN GOLD IDENTIFIES MULTIPLE GEOPHYSICAL TARGETS FROM 3D IP SURVEY AT THE BAJO PROJECT

Japan Gold Corp. has completed an expanded 3-D induced polarization (3-D IP) and resistivity geophysical survey at the Bajo project in Japan (see news release dated Feb. 26, 2026). A total of 37.6 line kilometres of 3-D IP was completed over an eight-kilometre-by-five-kilometre area at Bajo between February and May, 2026.

The 3-D IP survey was successful in identifying multiple chargeability and resistivity anomalies that are interpreted to be comparable with geophysical signatures observed in areas of historical mining. The survey was designed to characterize the geophysical response associated with known veins, including the Sakuru-Hi vein, which historically reported grades of up to 125.9 grams per tonne gold and 557 grams per tonne silver, and apply this interpretation across the eight-kilometre-long project area. Preliminary interpretations of the survey results suggest the presence of extensions and subparallel features that appear continuous across multiple survey lines, with interpreted strike lengths exceeding one kilometre. These interpreted anomalies show strong spatial correlation with mapped surface alteration, veins and structural trends across the project area.

With multiple prospective anomalies identified by the 3-D IP survey, the next phase of exploration will focus on target prioritization, followed by the planning and execution of a diamond drilling program in consultation with local stakeholders. The drilling program will be designed to test the highest-priority geophysical anomalies supported by the integrated geological and structural interpretation of the project area.

Community engagement

Japan Gold continues to engage with local communities and municipal leaders as part of its commitment to responsible and collaborative exploration at the Bajo project. In May, 2026, Japan Gold, in partnership with Zonge Engineering and Research Organization (Aust) Pty. Ltd., was proud to support a local community experiencing water supply challenges by conducting a resistivity survey to identify potential groundwater sources and evaluate suitable locations for a new water well. In June, 2026, members of Japan Gold's management team held a public consultation meeting with community members and local leaders to provide an update on continuing exploration activities and discuss future exploration plans within the project area.

Japan Gold remains committed to maintaining open communication with local stakeholders and working collaboratively with communities as exploration activities advance.
