Japan Gold Reports High-Grade Rock Samples and Commences Geophysical Exploration Programs over the Kitano-o Gold Prospect

Vancouver, British Columbia–(Newsfile Corp. – July 29, 2019) – Japan Gold Corp. (TSXV: JG) (“Japan Gold” or the “Company“) is pleased to report high-grade rock samples collected from historic mine dumps up to 60.8 g/t gold from the eastern side of the Kitano-o Gold Prospect. A prospect-scale gravity survey has commenced and plans for CSAMT geophysical surveys to further refine drill targets within the Kitano-o Gold District are well advanced. The Company announced commencement of Phase 1 scout drilling on the western and central parts of the 3-kilometre-long mineralized Kitano-o prospect in its news release of July 25, 2019.

The Kitano-o prospect is located within the Kitano-o Gold District, a 7 x 3 kilometre area which incorporates six old mines and workings, Figure 1. In excess of 96,000 ounces of gold at a grade of 5.9 g/t1 was produced prior to the government-imposed moratorium and mine closure in 1943. Gold was won largely from shallow open-pits in gold-bearing eluvium, and from selective hard-rock mining of narrow sub-sinter quartz veins and stockworks. Subsequently, much of the in-situ high-level quartz vein outcroppings across Kitano-o were mined to depths of 90 metres in underground workings.

The presence of outcropping sinter at Kitano-o prospect, implies the entire epithermal system is preserved, the numerous mineralized veins and stockworks excavated directly under the sinter indicate significant amounts of gold has leaked from boiling-zones at depth to the upper parts of the hot-spring system. The target at the Kitano-o prospect are these boiling-zones where most of the gold precipitates in epithermal systems and these generally occur from 150 metres to 250 metres beneath the paleo-water table (sinter level), and downward towards the lower basement contact.

Rock Chip Results

Work to refine drill targets in the eastern part of the Kitano-o prospect has included detailed geological mapping of the historic workings and the majority of samples were sourced from mine dumps and vein sorting areas located around these workings. Samples of quartz vein dump, sub-crop and float material were collected along an 800-metre east-west section of the east Kitano-o workings.

Of the 75 rock chips collected from east Kitano-o, 16 mine dump samples gave gold assay results greater than ≥2.5 g/t with a peak assay of 60.8 g/t . Noteworthy results include:

Quartz vein samples show well-developed colloform-crustiform textures containing bands of disseminated fine-grained black sulphide mineralization, termed ‘ginguro’. These veins were mined from shallow underground workings located immediately below the sinter [refer to Figure 2 and Plates 1 to 9].

Also of note in these samples and across the 3 kilometre mineralized system at the Kitano-o prospect are the low silver to gold (Au:Ag) ratios indicating the mineralizing event has a gold-bias relative to silver.

Pathfinder elements such as antimony are typically deposited in the top of the epithermal hot-spring systems and are well represented in mineralized sinter and sub-sinter samples collected at Kitano-o [Figure 3 and Plates 10 to 14].

East Kitano-o lies proximal to the basement unconformity / inferred graben-margin and emphasizes the possibility for unconformity-style vein targets akin to those at the Hishikari mine in Kyushu.

Results at east Kitano-o are consistent in tenor to samples previously collected at central and west Kitano-o and the entire 3-kilometre long system remains untested for deeper ‘boiling zone’ targets. Such targets are currently being drill tested at central and west Kitano-o.


The Company has commenced prospect-scale gravity surveying in order to better define the basement architecture and how this relates to plumbing or feeder structures of the epithermal vein system at Kitano-o. If deemed useful, other prospects in the Kitano-o Gold District will also be surveyed.

To further refine drill targeting, prospect scale CSAMT geophysical surveys are planned to commence in the near future at Kitano-o. Core samples taken from the current Phase 1 drilling at west and central Kitano-o will be petro-physically analyzed to better calibrate the CSAMT survey results and vector ongoing drilling.

Sampling Methods

Rock results presented herewith in this news release and accompanying figures are from 1-5 kg selected grab of outcrop, mine dump, sub-crop and float samples. The grab samples of float and dump material reported in this announcement are believed to originate from the underlying bedrock. The Company cautions that grab samples are selective by nature and may not be representative of typical mineralization on the property. Sample preparation and assaying were done by Intertek Testing Services (ITS), Muntinlupa City, Philippines. Gold was analyzed by 50 gram-charge Fire Assay and AAS finish. 48 multielement analysis including silver were done by four-acid digest and ICP-AES/MS determination.

The laboratory inserts its own blank, standards & sub-split pulp duplicates for Quality Control and reports these results accordingly. Results fall within acceptable levels of accuracy and precision.
