Japan Gold Corp.’s leadership team has long recognized Japan’s prospectivity for gold, silver and copper. When Japan’s mining laws were changed in 2012 to re-activate the mining industry, Japan Gold moved quickly to review historical data and identify key exploration targets and was the first foreign exploration company to apply for prospecting licenses.
The Tertiary volcanic arc terrains of Japan host 76 known past producing gold mines, including five one-million-plus-ounce gold deposits. This includes one of the world’s highest-grade gold mines, the Hishikari Mine on the island of Kyushu. The Hishikari Mine has produced over 7 million ounces of gold from 1985-2016 and continues to produce at a rate of ~200,000 ounces per year at an average grade of 40 g/t gold.
Despite a history of significant gold production and known mineral occurrences, however, Japan is regarded as largely underexplored.
Project Area Selection
Japan Gold has completed an extensive review of the Metal Mining Agency of Japan database, which includes detailed and relevant information about historical drilling results and mine production. Based on a desktop review of historical gold production and Japan’s extensive geoscientific database, Japan Gold pinpointed areas that are very compelling from a geological perspective.
The company has lodged 201 prospecting rights license applications on Japan's three main islands, Hokkaido, Honshu, and Kyushu. The applications cover a combined 66,477 hectares over 15 Projects with a focus on targeting high-grade epithermal gold veins analogous to the Hishikari model and lithocap/porphyry targets.
To date, 23 of 56 applications over the Ikutahara Project, and the nine applications covering the Eboshi Project have been granted as Prospecting Rights. The remaining applications have been accepted for further government review. This reserves the ground for Japan Gold and allows for surface forms of exploration such as mapping, geochemical sampling and geophysics.
Eleven of the 15 project areas target high-grade epithermal gold deposits.
Four of the 15 project areas target areas of gold-bearing advanced argillic alteration lithocaps, which could indicate the presence of a porphyry mineral environment.
Japan Gold Exploration Projects
From October to December 2016, six geologists and support teams undertook a nine-week field program, completing prospecting, geological mapping, collecting stream sediment BLEG and fine fraction drainage samples and rock float and outcrop sampling over the majority of the Ikutahara Project.
Results of the Ikutahara exploration program highlighted large coherent gold and gold-pathfinder anomalies over extensive drainage areas within the Ikutahara Project area. These results have been compiled to further define targets for additional detailed prospect mapping and surface geochemical surveys in conjunction with drill testing over priority targets in 2017.
Drilling permit applications have been filed and Japan Gold has purchased 3 compact, portable diamond core drill rigs and has signed a contract with Sumiko Resources Exploration & Development Co., Ltd., a wholly owned subsidiary of Sumitomo Metal Mining Co., Ltd., to manage and operate its drilling programs in Japan.
Mapping and geochemical sampling is ongoing at the the Ikutahara and Aibetsu Projects to further define new drill targets.
