Japan Gold Commences Next Phase of Drilling at Mizobe

Japan Gold Corp. (TSXV: JG,OTC:JGLDF) (OTCQB: JGLDF) ("Japan Gold" or the "Company") is pleased to announce the commencement of the next phase of diamond drilling at the 100% held Mizobe Project ("Mizobe") located in the Hokusatsu district on the southern island of Kyushu, one of Japan's most prospective epithermal gold areas. The drill program consists of a total of 4 holes for approximately 1,600m.

Previous drilling at Mizobe (completed through the Barrick Alliance, see news release dated February 29, 2024), confirmed the presence of gold mineralization underneath post mineralization. Best intercepts include: 10.0m @ 4.27g/t Au from 122.75m (MZDD23-003) and 4.0m @ 1.60g/t Au from 36.5m (MZDD23-004). Mineralization is associated with localised zones of silification, clay-pyrite alteration, narrow zones of hydrothermal brecciation and anomalous arsenic and antimony. This style of alteration and geochemical association is interpreted to represent the upper or peripheral parts of an epithermal system.

The 2025 Mizobe drill program is designed to test for higher grade mineralization below these intercepts, as well as testing resistivity and chargeability defined from the 2023 Induced Polarization survey.

Jason Letto, VP Exploration, said, "This phase of drilling is designed to build on the encouraging results from the 2023 campaign, leverage historical data, geophysics, geochemistry, and structural interpretation to refine targeting and to increase our understanding of the mineralized system at Mizobe. We are systematically testing an area within proximity of the 14 million ounce^[1] Hishikari gold mine and look forward to advancing Mizobe and other prospects in the Hokusatsu district."

The Mizobe Project

The Mizobe Project is located in the Hokusatsu district of southern Kyushu in a similar geological setting to the Sumitomo Metal Mining Co., Ltd. Hishikari Mine, located 23 kilometres to the north. Hishikari is one of the world's highest-grade gold mines and currently Japan's only active large-scale producing gold mine. The Hokusatsu district has produced more than 13 million ounces^[2] of gold from several mines and remains one of the most prospective regions in Japan.
