Japan

In Japan, Irving is focused on identifying high-silica, high-grade epithermal Au-Ag veins that could potentially be suitable for use as smelter flux in the many operating base metal smelters throughout the country. Recovery of precious metals occurs during the smelting and refining process.

In August 2016, Irving’s wholly-owned subsidiary, Irving Resources Japan GK, (IRV Japan) secured the 2.98 sq km Omui mining license on the island of Hokkaido, Japan. To augment its land position, IRV Japan filed 39 prospecting licenses covering an additional 131.7 sq km of prospective ground encompassing the entirety of the northeast-trending Omu volcanic graben, host to multiple high-grade epithermal Au-Ag veins exploited at the historic Omui and Hokuryu mines prior to World War II. Irving believes the Omu volcanic graben has potential to host significant undiscovered high-grade veins.

At Utanobori, about 30 km northwest of Omui, IRV Japan has filed 26 prospecting licenses covering 88.1 sq km in an area where historic samples of epithermal veins reportedly contain very high grades of silver (+1,000 gpt) and lesser gold.

At Rubeshibe, approximtely 60 km southeast of Omui, IRV Japan has filed 56 prospecting licenses covering 188.8 sq km in an area where epithermal Au-Ag veins appear associated with late-stage rhyolite domes that have intruded intermediate and felsic volcanic rocks belonging to a broad volcanic graben.

Acceptance of prospecting applications at Omui, Utanobori and Rubeshibe was granted by the Ministry of Economy, Trade and Industry (METI), Hokkaido Bureau, and a multi-step review for final approval has now begun. Mitsui Mineral Development Engineering Co., Ltd. (MINDECO) is assisting Irving throughout this process.
