The relevant Japanese government department has accepted its application for 15 new prospecting areas, covering 3,990 hectares on the Noto Peninsula region of Honshu Island.
This covers a 7km long zone of alteration and historic gold mining known as the Togi Goldfield.
This is the site of historic mine workings, which produced 48,000 oz (ounces) of gold between 1910 and 1921, including 16,500 ounces at 14 g/t (grams per ton) of gold, the firm said.
"The Togi Goldfield represents another highly prospective yet under-explored area in Japan," said John Proust, chairman and CEO of Japan Gold.
"The scale of the alteration corridor, shallow workings along it, and evidence of preservation of the epithermal system from sinter exposures are very encouraging. Japan Gold looks forward to advancing the Togi Project along with the rest of its regionally diverse portfolio."
Gold mineralization was first discovered in the Togi area in 1896 and deposits mined in the area are divided into the Hirochi deposits in the northeast and Urugami deposits in the southwest
The Mori vein from the Hirochi group produced 16,500 ounces of gold at an average grade of 14 g/t. The vein is reported to be up to four metres wide, with gold values ranging between 8 and 20 g/t gold.
Records show that mineralisation at lower mine levels are open at depth with average grades of 8.12 g/t gold and 56.9 g/t silver.
Meanwhile, the Togo Mine, the largest within the Urugami area, generated more than 18,000 ounces of gold and 83,000 oz of silver from stockwork vein and breccia zones.
Thirteen gold projects
The firm has 13 gold projects (on the three largest islands of Japan--Hokkaido, Honshu and Kyushu), which cover areas with known gold occurrences, a history of mining and are prospective for high-grade epithermal mineralization.
It also has five lithocap projects which could indicate the presence of porphyry mineralization.
