VANCOUVER – Japan Gold Corp. [JG-TSXV; JGLDF-OTCQB] reported high-grade gold-silver intercepts from its first drill holes at the Ryuo prospect, within the Ikutahara project on Hokkaido Island, Japan. The Ikutahara project is 100% held by Japan Gold and is not included in the Barrick alliance.
The Ryuo prospect hosts five areas of workings along a 1-km open-ended trend of alteration and mineralization developed prior to the government-imposed closure in 1943. Three initial scout drill holes totalling 828.3 metres were completed between May and July, 2021.
Drill hole IKDD21-001 targeted down-dip extensions of high-grade gold-silver mineralization historically mined at the Jinja vein. A broad mineralized interval was encountered and returned 4.9 metres of 12.1 g/t gold and 33.0 g/t silver from 60.6 m, including 0.9 m at 18.4 g/t Au and 115.8 g/t Ag from 60.6 m and 1.95 m at 20.5 g/t Au and 21.0 g/t Ag from 63.55 m, including 0.55 m at 59.4 g/t Au and 49.5 g/t Ag from 63.9 m, including 0.25 m at 125.0 g/t Au and 97.0 g/t Ag from 64.2 m.
Drill hole IKDD21-001 shows that high-grade gold and silver mineralization remains open to depth below the Jinja vein workings and, having a true width of 4.74 metres, is significantly wider than average vein widths reported historically in the underground workings.
Drill hole IKDD21-003, located 550 metres southwest of IKDD21-001, on a separate parallel structure, targeted mineralization below the Ryuei historical workings. Four separate zones of hydrothermal breccia up to 20 metres in downhole width were intersected down the length of the 350-metre drill hole.
Zones of fine-grained or chalcedonic quartz and quartz-sulphide vein fill within the breccias included 2.12 metres of 6.3 g/t gold and 12.6 g/t silver from 81.2 metres, including 1.32 m at 8.9 g/t Au and 17.6 g/t Ag from 81.55 m, including 0.3 m at 14.8 g/t Au and 27.8 g/t Ag from 81.95 m and 0.5 m at 3.1 g/t Au and 7.2 g/t Ag from 119.7 m.
Drill hole IKDD21-002 targeted the northeast strike extension of the Shouei vein and a coincident CSAMT (controlled source audio-frequency magnetotelluric) resistivity geophysical anomaly. The drill hole failed to intersect a significant vein zone apart from a narrow quartz-stockwork/faulted zone interpreted as the northeast extension of the Shouei structure.
“The initial drill holes at Ryuo have confirmed wide high-grade vein mineralization is continuous below the historical workings closed in 1943. The Ryuo prospect has never been drilled and these initial results provide strong encouragement to continue drilling at Ryuo, and the other similarly underexplored Ikutahara prospects,” said vice-president of exploration, Andrew Rowe.
Drilling resumed September 6 to test the lateral strike extensions of the intercept in IKDD21-001 at the Jinja vein. A second drill rig is targeting a vertical CSAMT resistivity anomaly below the Taisei workings.
