Japan Gold starts next phase of drilling at Mizobe

Executive Summary

• Japan Gold Corp. has begun the next phase of diamond drilling at its wholly‑owned Mizobe project in Kyushu, targeting higher‑grade mineralization below previous intercepts.
• The 2025 program comprises four holes totaling ~1,600 m and will test targets identified by a 2023 induced‑polarization survey.
• Prior drilling (2023) returned notable intercepts of 10.0 m @ 4.27 g/t Au and 4.0 m @ 1.60 g/t Au, confirming gold mineralization beneath post‑mineralization zones.

Key Details

• Drill Program: 4 holes, ~1,600 metres total depth planned for 2025 at Mizobe (Hokusatsu district, Kyushu).
• Objective: Test for higher‑grade Au below existing intercepts and evaluate resistivity/chargeability anomalies from the 2023 IP survey.
• Previous Intercepts (2023):
• Hole MZDD23‑003 – 10.0 m @ 4.27 g/t Au from 122.75 m depth.
• Hole MZDD23‑004 – 4.0 m @ 1.60 g/t Au from 36.5 m depth.
• Geological Context: Mineralization associated with silification, clay‑pyrite alteration, narrow hydrothermal brecciation zones, and anomalous As/Sb—interpreted as peripheral epithermal system.
• Exploration Rationale: Proximity to the 14‑million‑ounce Hishikari gold mine; aims to refine targeting using historical data, geophysics, geochemistry, and structural interpretation.
• Management Comment: Jason Letto, VP Exploration – “This phase of drilling is designed to build on the encouraging results from the 2023 campaign… we look forward to advancing Mizobe and other prospects in the Hokusatsu district.”
• Marketing Services Agreement (non‑material): Entered Aug 26 2025 with Canacom Group for digital marketing services, $100,000 fee over 12 months.
