Japan Gold drills 10 m of 4.3 g/t Au at Mizobe

THE JAPAN GOLD - BARRICK ALLIANCE ENCOUNTERS WIDE INTERVALS OF GOLD MINERALIZATION IN ITS INITIAL DRILL PROGRAM AT THE MIZOBE PROJECT

Japan Gold Corp. has released results of its initial framework drilling program at the Barrick Alliance Mizobe project in southern Kyushu, Japan. Drilling has encountered wide and locally high-grade intervals in the initial, broad-spaced framework drill program.

Highlights: Drill holes MZDD23-001, 002 and 003 successfully intersected gold mineralized intervals including the following notable results (all intervals are down-hole lengths):

  • MZDD23-003: 10 metres at 4.3 grams per tonne gold and 6.6 g/t silver from 122.75 m (including four m at 6.2 g/t Au and 10.2 g/t Ag) and 14.1 m at one g/t Au and 4.8 g/t Ag from 176.95 m;
  • MZDD23-002: 6.1 m at 1.4 g/t Au and 7.5 g/t Ag from 126.7 m (including 2.6 m at 2.2 g/t Au and 10.6 g/t Ag).

Mizobe project

The Mizobe project is located within the Hokusatsu region of southern Kyushu, Japan's largest gold producing district, with more than 11 million ounces of combined production from low-sulphidation epithermal deposits.

Within the Mizobe project, historical mining activities focused on antimony-rich hydrothermal breccias at the Semari and Nakazon workings, prior to 1942. In 2000, the Metal Mining Agency of Japan (MMAJ) drill hole 12MAHT-2 was drilled one kilometre to the southeast of the historical antimony workings, targeting a geophysical anomaly; the drill hole intersected a down-hole mineralized interval of 43.35 m at 0.9 g/t gold, with an included interval of 20.3 m at 1.2 g/t gold. No further drilling was completed around this mineralized intersection.

Sampling by the alliance of discontinuous outcrop and quartz-vein/breccia float across a two by 2.5 km area showed strong anomalism with channel samples including 24.7 m grading one g/t gold, and river float samples up to 18.9 g/t gold. The extent of gold and antimony anomalism was seen as highly encouraging considering much of the target area is concealed by a veneer of postmineral volcanic ash.

Drilling results

The three initial, widely spaced framework drill holes at Mizobe targeted interpreted structural extensions below postmineral volcanic ash on large stepouts between 600 and 1,000 m from known surface mineralization and historical drilling data. Gold mineralization intersected includes both vein- and breccia-hosted styles. The significant widths of mineralization intersected in drilling below postmineral cover, and the broad footprint of gold and pathfinder mineralization identified in channel sampling at surface indicate the potential of a significant gold-bearing hydrothermal system at Mizobe. Next steps at Mizobe will include stepout drilling to further extend and define the geometry of the wide mineralized intervals. Further drilling will be scheduled at Mizobe around geophysical work programs already in progress on the high-priority Aibetsu and Togi alliance projects in Hokkaido and Honshu.

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 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 Urushi Village, near 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 senior project geologists.

Sample lengths varied from 0.25 to one m, depending on the positions of geological contacts and variations in alteration composition. The core was split by diamond rock saw supervised by project geologists. The 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 0.25 kilogram and five kilograms 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, pulverized and assayed for gold 50-gram charge fire assay/atomic absorption spectroscopy finish (Au-AA24; 0.005 ppm (part per million) lower detection limit) and a 48-multielement by four-acid digest with inductively coupled plasma mass spectrometry determination (ME-MS61L; Ag 0.002 ppm lower detection limit). Overlimit Au and Ag samples were reassayed by fire assay and gravimetric finish (GRA-22, LDL of 0.5 and five 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 and geochemical standards. It reports these results with the certified assay report. Laboratory procedures and quality assurance/quality control protocols adopted are considered appropriate. The CRMs and internal QA/QC results fall within acceptable levels of accuracy and precision and are considered to lack any bias.

Rock results presented in this news release are from one to three kg selected grabs of river float samples, and continuous chip-channel samples. The grab samples of float material reported in this announcement are believed to originate from the underlying bedrock of the drainage basin from which they were collected. The company cautions that grab and float samples are selective by nature and may not be representative of typical mineralization on the property. Composited chip-channel samples have been collected continuously along exposures of bedrock at intervals between 0.5 and 1.5 m. Sample preparation and assaying were done by ALS Perth, Western Australia, Australia. Samples were crushed and pulverized and gold was analyzed by 50-gram charge fire assay and AAS finish. A 48-multielement analysis including silver was done by four-acid digest and ICP-MS determination.
