- The Tobaru project is located within the highly gold endowed Hokusatsu-Kushikino mining district. In excess of 10 million ounces of gold has been produced from high grade epithermal deposits of the district. Notable gold producers within the district include: the Hishikari mine with 7.4 million ounces produced to date at average grades of 30-40 g/t6; Kushikino mine, 1.8 million ounces at 6.7 g/t; Yamagano mine, 910,000 ounces at 17.4 g/t; and the Ohkuchi mine with 714,000 ounces at 13.6 g/t4,7, Fuke mine, 106 Koz gold4.
- The presence of a large zoned hydrothermal-alteration system (1,500 by 700 metres) with a central advanced argillic core provides a compelling target within the context of the district. The alteration zone represents a significant exploration target for shallow-level epithermal gold and deeper porphyry copper-gold deposits.
- A joint venture between Mitsui Mining & Smelting Company and BHP-Utah Japan Inc. explored the Tobaru area in the 1980’s and 1990’s.
