Japan Gold Commences Next Phase of Drilling

at Mizobe

Vancouver, British Columbia--(Newsfile Corp. - September 9, 2025) -

Japan Gold Corp. (TSXV: JG)

(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.
