Japan Gold Announces Positive Results from Geophysical Surveys at the Ohra-Takamine Gold Project
NEWS RELEASE
Japan Gold Announces Positive Results from Geophysical Surveys at the Ohra-Takamine Gold
Project
Vancouver, British Colum bia- April 08, 2020 - Japan Gold Corp. (the “Company”) (TSXV:JG)
(OTCQB:JGLDF) is pleased to announce encouraging results from geophysical work programs
completed at its Ohra-Takamine Gold Project in southern Kyushu. Comprehensive programs completed
during January and February, 2020 covered a substantial portion of the 8- kilometer Ohra-Takamine
historic mine corridor and included controlled source audio- frequency magnetotellurics (“CSAMT”)
and detailed ground-gravity geophysical surveys.
Highlights:
• A 35 line -kilometer, grid-based, CSAMT geophysical survey was completed along a 4.2
kilometer portion of the Ohra-Takamine Mine corridor
• The CSAMT geophysical survey at the Ohra -Takamine Project was undertaken to identify
zones of sub-surface electrical resistivity and conductivity, representing silicification and clay
alteration related to epithermal vein systems
• Results of the CSAMT survey at Ohra-Takamine are very encouraging and have defined a
number of linear kilometric-scale, contiguous resist ive zones (CSAMT anomalies), locally
extending to depth across the survey area
• Prospect-scale gravity readings were collected over an 8 by 4 kilometer area with nominal 60
to 100 metre spacings along access roads and ridgelines and merged with Geological Survey of
Japan gravity data to produce a new suite of processed gravity images
• Results of the gravity survey define basement uplift or doming along a northeast oriented
structural zone along which the mine corridor is hosted
• Geophysical surveys completed to date are adding a vital third dimension to the epithermal
targets at the Ohra-Takamine Project.
The Ohra-Takamine Gold Prospect lies within the highly gold endowed Southern Kyushu Epithermal
Gold Province, and hosts five historic gold mines , the Matsuno, Urushi, Takamine, Ohra, and Aira
Yamada Mines, which define a northeast oriented structural corridor, Figure 1. In excess of 11 million
ounces of gold has been produced from high- grade low-sulphidation epithermal gold deposits in the
province; notable producers include; the Hishikari Mine with 7.8 million ounces of gold produced to
date at average grades of 30-40 g/t Au1; Kushikino Mine, 1.8 million ounces at 6.7 g/t Au; Yamagano
Mine, 910,000 ounces at 17.4 g/t Au; and the Okuchi Mine with 714,000 ounces at 13.6 g/t Au2,3.
CSAMT Survey
A 35 line -kilometer, grid -based, controlled source audio- frequency magnetotellurics (CSAMT)
geophysical survey was completed by Zonge Geophysics Pty. Ltd. during January and February 2020,
over a 4.2 kilometer-length of the Ohra-Takamine Mine corridor. The survey comprises 22 individual,
north-south orientated CSAMT grid lines varying from 1.5 to 1.8 kilomet ers in length, spaced 200
metres apart. The grid is staggered along an east-northeast orientation, parallel to the trend of the historic
mine corridor and mapped alteration system.
Gravity Survey
Bouguer gravity data was acquired by Haines Surveys Pty. Ltd. during January and February 2020,
over an approximate 8 by 4-kilometer area, centred on the Urushi -Takamine-Ohra mine corridor. 973
gravity station reading s were acquired at nominal 60 to 100 me tre spacings along access roads and
ridgelines and merged with gravity data from the Geological Survey of Japan to produce a suite of
processed gravity images; including a terrain corrected Bouguer anomaly map, first order trend
removed, vertical derivative, Gaussian residual, Hanning filtered residual and horizontal gradient maps.
Conclusions from CSAMT and Gravity Geophysical Surveys
The CSAMT geophysical survey at the Ohra-Takamine Gold Project was undertaken to identify zones
of sub-surface electrical resistivity and conductivity , representing silicification and clay alteration
respectively, related to epithermal vein systems.
Results of the CSAMT survey at Ohra -Takamine are very encouraging and have defined a number of
linear kilometric-scale, contiguous resist ive zones (CSAMT anomalies), locally extending to depth
across the surveyed area, Figure 2. In the eastern part of the grid, a contiguous, linear resistive zone is
defined across multiple sections, coincident and parallel to the trend of mineralisation at the Takamine
Mine and extending to the northeast, through and beyond the Ohra Mine. This resistive zone coincides
with surface mapped hydrothermal clay alteration, which typically forms above and laterally around
the upper portions of large epithermal vein systems. A similar, contiguous resistivity zone commences
600 meters to the east of the Urushi Mine, extending in a westerly direction below the mine to the edge
of the CSAMT grid. The resistivity anomalies mapped along the Urushi Mine trend, occur largely below
a veneer of younger volcanic ash cover and alluvium. Additional, linear resistivity anomalies have been
defined to the north and south of the main mine corridor; their trends are both sub-parallel, and oblique,
to the trend of the historical workings in these mines.
The definition of structural architecture and faulting which allows pathways for hydrothermal fluid
flow, and subsequent quartz vein formation is a key factor in the interpretation of CSAMT results. With
this in mind, detailed gravity surveying was undertaken to further define faulting. Initial findings from
gravity show the Urushi, Takamine and Ohra Mines are located on the northwest shoulder of a
prominent gravity ridge, Figure 3. The spatial relationship between gravity highs and the major low-
sulphidation epithermal gold deposits in the province is well described in the literature, and uplift or
doming of the underlying basement, producing gravity anomalies, is interpreted as a key factor in the
development of deep-seated fracture pathways for hydrothermal fluid flow, and subsequent quartz vein
development in these mines.
In the coming weeks the gravity data collected by the Company will undergo additional processing to
contour rapid changes in gravity gradient, providing more definition of the fault architecture related to
gold mineralisation.
Soil and Rock Chip Sampling
An extensive 6.4 by 3.3- kilometer grid-based soil sampling program comprising 1,470 soil and 188
rock samples was completed in March 2020 along the mine corridor , and recently dispatched for
analysis. The samples will undergo gold and multi-element geochemical assay and spectral clay
analysis and will be included in the compilation of a comprehensive geological, geochemical, and
geophysical data set. Assay results from the soil and rock chip samples are expected within the next 4
weeks.
Geophysical surveys completed to date are adding a vital third dimension to the epithermal targets at
the Ohra-Takamine Project. In the coming weeks, additional structural information from further gravity
processing and systematic surface geochemical and alteration map s will provide vector s for ground
truthing of anomalies, and refinement of new drill targets.
