Vancouver, British Columbia--(Newsfile Corp. - July 9, 2025) - Japan Gold Corp. (TSXV: JG) (OTCQB: JGLDF) ("Japan Gold" or the "Company") is pleased to announce that the initial framework drill program at the Barrick Alliance Hakuryu Project intersected gold mineralization across narrow intervals of the Hakuryu No. 3 Vein target. The Hakuryu No. 3 Vein is located on the northeastern edge of a 5km long anomalous gold trend contained within the Hakuryu Project[1], (Figure 1). The Hakuryu Project sits in the Konomai Mine district, which had historic production of 2.35 million ounces of gold.
Assay highlights include:
- 16.2 g/t Au over 0.6 meters (Drill hole: DDH-HAK-001), from 103.8 meters
(a reassay of this interval yielded 24.1 g/t over 0.6 meters, from 103.8 meters)
- 1.5 g/t Au over 3.3 meters (Drill hole: DDH-HAK-002), from 164.2 meters
Full results are presented in Tables 1 and 2.
Assay results indicate that two drillholes (DDH-HAK-001 & DDH-HAK-002) intersected anomalous gold mineralization. The mineralization is associated with a zone of hydrothermal brecciation which sits on the hanging wall side of a well-developed fault zone. The mineralization in both holes is associated with the same structural zone, indicating continuity of the mineral intersection over 145 metres of strike. Drillhole 3 (DDH-HAK-003) targeted the same structural zone but did not intersect anomalous gold, possibly due to a structural offset from faulting.
The results from the drilling are encouraging, confirming anomalous gold mineralization including the presence of high-grade mineralization within a zone of well-developed faulting and brecciation. Although no primary epithermal veins were encountered, this largely untested structural zone is part of a much more extensive corridor of alteration that extends for over 5km.
Chairman and CEO, John Proust, commented, "We are encouraged by the positive results from the maiden drill campaign at Hakuryu, which provided early indicators for significant gold mineralisation across the project. It was an important first step in the exploration of the historically well-endowed Konomai epithermal gold district. Advanced geophysics in conjunction with the geological results of the drill program will define and guide additional drilling of this largely untested prospective broader corridor."
Located on the Japanese island of Hokkaido, the Hakuryu drill program was designed to test beneath a prominent zone of surface silicification and quartz veining identified through geological mapping and supported by geochemical datasets, where surface sampling of this zone returned gold values between 0.1g/t Au to 3.0g/t Au. Originally planned for four drill holes totaling up to 700 meters, three holes totaling 568 meters were sufficient to effectively evaluate the immediate target (Figure 2 and 3). The program was fully funded by Barrick Mining Corporation under the strategic alliance with Japan Gold. Exploration activities are jointly overseen by the Japan Gold/Barrick Technical Committee.
Drill sites were fully rehabilitated to their original condition, with work completed in alignment with environmental best practices.

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 PMC-700 drill rig owned and operated by the Company. The drilling program was fully supervised by Company senior geologists at the drilling site.
The drill core was collected in plastic core trays at the drill site and transported by road in Company vehicles to its core handling facility in the nearby Ikutahara Town, Engaru City, near the project area. The drill core was carefully logged, photographed and sample intervals were marked up along predicted mineralized and unmineralized intervals along the entirety of the drill holes by Japan Gold senior project geologists.
Sample lengths varied from 0.5 to 2.4 metres, depending on the positions of geological contacts and variations in alteration composition. The core was split by a 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 0.9 to 8.0 kilograms depending on the sample length and core size. A chain of custody was established between the Company and the receiving laboratory to ensure the integrity of the samples during transportation from the 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 / 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 the 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 procedures and QA/QC protocols adopted are considered appropriate. The CRMs and internal QA/QC results fall within acceptable levels of accuracy & precision and are considered to lack any bias.
