Japan Gold Intersects High-Grade Veins in First Drill Holes at the Ryuo Prospect
September 14th, 2021 – Vancouver, BC – Japan Gold Corp. (TSX-V: JG) (OTCQB: JGLDF) (“Japan
Gold” or the “Company”) is pleased to report high-grade gold-silver intercepts from its first drill holes at
the Ryuo Prospect, within the Ikutahara Project, Figure 1. The Ikutahara Project is 100% held by Japan
Gold and is not included in the Barrick Alliance.
The Ryuo Prospect hosts f ive areas of workings along a 1 km open ended trend of alteration and
mineralization that were developed prior to the government-imposed closure in 1943. T hree initial scout
drill holes totaling 828.3 m were completed between May and July 2021. Figure 2 shows the geology of
the Ryuo Prospect area, the location of the completed drill holes and the pads permitted for future drilling.
Table 1 summarizes the drilling results.
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 (reported as downhole intervals)
with the following results:
4.9 m @ 12.1 g/t Au & 33.0 g/t Ag from 60.6 m
(incl. 0.9 m @ 18.4 g/t Au & 115.8 g/t Ag from 60.6 m)
(and 1.95 m @ 20.5 g/t Au & 21.0 g/t Ag from 63.55 m)
(incl. 0.55 m @ 59.4 g/t Au & 49.5 g/t Ag from 63.9 m)
(incl. 0.25 m @ 125.0 g/t Au & 97.0 g/t Ag from 64.2 m)
The intersection in 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 m, is significantly wider than average
vein widths reported historically in the underground workings (See Figures 3 and 4).
The intercepted vein zone exhibits multiple phases of hydrothermal brecciation, quartz and quartz-sulphide
veining, including ginguro banding. The q uartz vein textures are very fine -grained or chalcedonic,
indicating the quartz veining is still high in the hydrothermal system and that mineralization should persist
to depth.
Drill hole IKDD21-003, located 550 m 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
m in down-hole width were intersected down the length of the 350 m drill hole (Figure 5). Zones of fine-
grained or chalcedonic quartz and quartz -sulphide vein-fill within the breccias included the following
mineralized intercepts (reported as downhole intervals):
2.12 m @ 6.3 g/t Au & 12.6 g/t Ag from 81.2 m
(incl. 1.32 m @ 8.9 g/t Au & 17.6 g/t Ag from 81.55 m)
(incl. 0.3 m @ 14.8 g/t Au & 27.8 g/t Ag from 81.95 m)
2
and
0.5 m @ 3.1 g/t Au & 7.2 g/t Ag from 119.7 m
These multiple phases of hydrothermal brecciation, quartz and quartz -sulphide veining in IKDD21- 003
may represent the upper , flared portions of an epithermal vein system which could possibly coalesce at
depth (Figure 5). Elevated path-finder element geochemistry including antimony, arsenic, and mercury
associated with the hydrothermal breccias supports this model.
Drill hole IKDD21-002 targeted the northeast strike extension of the Shouei Vein and a coincident CSAMT
resistivity geophysical anomaly, Figure 2. The drill hole failed to intersect a significant vein zone apart
from a narrow quartz-stockwork / faulted zone which is interpreted as the northeast extension of the Shouei
structure. Workings at the Shouei Vein were as extensive as those at the Jinja Vein , but no detailed
underground sampling data exists. Historical reports however indicate two parallel veins were exploited at
Shouei with shoots that carried gold and silver grades comparable to those at the Jinja Vein1,2. Based on the
drill result at the Jinja Vein, 300 m to the northwest, further drilling will be required to test down-dip and
southwest strike extensions of the Shouei Vein which remain open.
“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 drill ing at Ryuo, and the other similarly under -explored
Ikutahara prospects.” Commented, Japan Gold’s Vice President of Exploration, Andrew Rowe.
Additional Drilling
Drilling recommenced on the 6 th of September 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 that
lies below the Taisei workings. Up to five additional drill holes are planned to be completed by the end of
November at the Ryuo Prospect.

The Ryuo Prospect
At the Ryuo Prospect, f ive areas of workings were developed along a 1 km long, open ended trend of
alteration and mineralization prior to the government -imposed closure in 1943. Underground sampling
carried out in the 1950’s in the Jinja Vein workings revealed high- grade gold- silver mineralization
including ‘level 4’ of the workings, which was sampled along a 72 m strike length giving an average
grade of 40.8 g/t Au and 193 g/t Ag, average vein width approximately 0.5 m. Figure 3 illustrates a long-
section of the Jinja vein workings with the underground sampling reported by the Metal Mining Agency
of Japan (MMAJ) 3 and the IKDD21 -001 vein pierce -point. High-grade gold/silver quartz veins were
mapped on all four of the lower levels of the Jinja vein system. Chip-channel samples were collected across
the veins at intervals spaced between 0.3 m and 4.7 m along strike.

published by the MMAJ and the Company has not resampled the underground workings or re -assayed
samples. The MMAJ report does not refer to QA/QC protocols followed historically.
Sampling Techniques and Assaying
The drilling results discussed in this news release are from drill core samples obtained by PQ, HQ and
NQ-size triple-tube diamond core drilling using a PMC700 and PMC-400 man-portable drill rigs owned
and operated by the Company. The drilling program was fully supervised by Company senior geologists at
the drilling site.
Drill core was collected in plastic core-trays at the drill site and transported by road in Company vehicles
to its core shed storage facility in the nearby Ikutahara Village, located centrally within the project area.
The drill core was carefully logged, photographed and sample intervals marked- up along predicted
mineralized and selected unmineralized intervals by Japan Gold KK senior project geologists and VP
Exploration.
Sample lengths varied from 0.1 to 1.0 m; depending on the positions of geological contacts and variations
in vein texture and composition. The core was split by diamond rock saw supervised by project geologists.
Half-core sample was collected from the entire length of each designated sample interval and placed into
individual-labelled, self-sealing calico bags for secure packaging and transport to the laboratory. The half-
core samples weighed between 0.2 to 5 kg depending on the sample length and core size. A Chain- of-
Custody was established between the Company and receiving laboratory to ensure the integrity of the
samples during transportation from site to the lab. The samples were sent in batches to ALS Laboratories
in Vancouver, Canada for sample preparation and assaying.
Samples were crushed, pulverised and assayed for gold 50 g charge Fire Assay/ AAS Finish (Au -AA24;
0.005 ppm lower detection limit) and a 48 multi-element by 4-acid digest with ICP-MS determination (ME-
MS61L; Ag 0.002 ppm lower detection limit). Over-limit Au and Ag samples were re-assayed by fire-assay
and gravimetric finish (GRA-22, LDL of 0.5 and 5 ppm for Au and Ag respectively).
Certified Reference Materials (CRMs) were inserted by Japan Gold KK at every 20th sample to assess
repeatability and assaying precision of the laboratory. In addition, the laboratory applied its own internal
Quality Control procedure that includes sample duplicates, blanks & geochemical standards. They report
these results with the certified Assay Report. Laboratory p rocedures and QAQC protocols adopted are
considered appropriate. The CRMs and internal QC -QA results fall within acceptable levels of accuracy
& precision and are considered to lack any bias.
