- The Onne Project covers the historic Onne gold-silver and Niko mercury mines. At Onne the epithermal quartz veins are developed along east-northeast to east-west orientated structures. Minor production in the years of 1936 and 1928 reported average gold grades of 5 g/t gold and 15 g/t gold respectively.
- The Fujimi Project covers the historic Fujimi and No.2 Tateushi gold-silver mines and surrounds.
- At Fujimi, five quartz veins hosted in rhyolite were mined in the 1930’s minor production records noted an average grade of 15 g/t gold and 20 g/t silver1.
- The No.2 Tateushi mine had exploration development carried out in the late 1930’s, however this work was probably curtailed by the government moratorium and closure of gold mines in Japan in 1943.
- Proven high-grade mineralization in the form of quartz-chalcedony-adularia-sericite±calcite quartz vein swarms, with underground sampling results including 2 m @ 31.7 g/t Au & 70 g/t Ag, and 3 m @ 11.3 g/t Au & 36 g/t Ag at Fujimi1.
- A genetic relationship exists between epithermal gold mineralization and high-level mercury present in several mercury mines located within and immediately around the project area, suggesting post-mineral erosion of the system is limited.
- No modern systematic exploration or exploration drilling to test for lateral and vertical extensions to the known, historically mined veins has been completed.
- Japan Gold proposes to explore the potential link between mercury and epithermal gold mineralization in both license application areas.
- Exploration to date is limited to the area of known veins and no exploration drilling has been completed to test the deeper extensions to the veins historically mined to a shallow level.
- Japan Gold will seek to define the limits of the hydrothermal alteration cells around the historic mines and use surface mapping and geochemistry to target new zones and extensions to previously exploited vein systems for testing by scout drilling.
