Japan Gold Corp. [JG-TSXV; JGLDF-OTCQB] reported results from seven additional drill holes at the Ryuo prospect. Drilling has continued to encounter high-grade veins along the Ryuo alteration corridor, and interpretation of drill core has significantly advanced the understanding of controls on mineralization at the prospect. The Ryuo prospect is located within the 100%-owned Ikutahara project in Hokkaido, Japan.
Summary of high-grade intercepts: IKDD22-005 has proven continuity of the Shouei vein 100 metres to the southwest of the historical workings includes the following high-grade zone from within a broader mineralized vein structure that returned 0.75 metres at 22.5 g/t gold and 41.3 g/t silver from 276 metres.
IKDD22-002 proved continuity of mineralization 50 metres below the 2021 drill intercept from IKDD21-010, which intersected 20 metres at 6.3 g/t gold and 15.7 g/t silver, giving the following significant interval that returned 0.4 metres at 19 g/t gold and 15.7 silver from 280.95 metres, including 0.2 metres at 34.6 g/t gold and 25 g/t silver from 280.95 metres.
IKDD22-007 targeted mineralization below IKDD21-008, which intersected the ultrahigh-grade interval of 0.45 metres at 1,395 g/t gold and 768 g/t silver. The drill hole stopped in mineralization well short of its target depth under difficult drilling conditions and due to a temporary expiry of a local forestry permit, with the following significant intervals: 1.1 metres at 2.9 g/t gold and 11.7 g/t silver from 266.8 metres (including 0.35 metres at seven g/t gold and 22.1 g/t silver from 267.25 metres); 0.4 metres at 12.8 g/t gold and 35.3 g/t silver from 288.4 metres, including 0.2 metres at 23.7 g/t gold and 74.7 g/t silver from 288.6 metres.
Andrew Rowe, Vice President Exploration stated, “We are very encouraged by the recent findings at the Ryuo prospect. The combination of multiple high-grade vein structures with high-level vein textures and a well-preserved alteration system supports deeper drilling, particularly along strike to the southwest of the prospect. We look forward to completing another round of drill holes to test these concepts before the end of this year.”
The 2022 drill program has significantly advanced the understanding of geological controls and alteration zonation with respect to high-grade mineralization at Ryuo. Importantly, high-grade gold events have been identified along the length of the prospect in multiple parallel vein zones, and alteration studies prove the system is well preserved.
IKDD22-005 has proven an extension of the Shouei vein mineralization 100 metres southwest. Further step-out drilling is required to confirm strike continuity to depth below veining intersected in the top of drill hole IKDD21-005, and towards the open high-grade mineralization intersected 400 metres southwest in drill holes IKDD21-008 and IKDD22-007.
IKDD22-007 targeting the depth extension of the ultra high-grade vein in IKDD21-008 (0.45 metres at 1,395 g/t gold and 768 g/t silver) terminated more than 100 metres before target depth under difficult drilling conditions and due to a temporary expiry of a local forestry permit. Numerous banded quartz veins cut the brecciated rhyolite carrying anomalous gold along its length, with higher grade intervals including the 40-cm vein from the bottom of the hole which gave 12.8 g/t gold and 35.5 g/t silver with a high-grade included interval of 23.7 g/t gold and 64.7 g/t silver.
Ongoing drilling will focus on targeting the deeper portions of the Ryuo hydrothermal system for high-grade mineralization associated with in the chlorite-illite zone.
The Ryuo Prospect consists of five areas of workings; Jinja, Shouei, Taisei, Ryuei and Buryu that were developed along a 1.2-km long, open ended trend of alteration and mineralization prior to the government-imposed closure in 1943.
Eleven new prospecting rights were lodged to cover prospective Miocene volcanics immediately to the north and west of the Ryuo prospect to ensure coverage of potential strike and parallel extension to the Ryuo mineralization. The new applications comprising a total of 2,567 hectares have now been accepted by the Ministry of Economy Trade and Industry (METI) Hokkaido.
Japan Gold is a Canadian mineral exploration company focused solely on gold exploration across the three largest islands of Japan: Hokkaido, Honshu and Kyushu. The company has a country-wide alliance with Barrick Gold Corp. [ABX-TSX; GOLD-NYSE] to jointly explore, develop and mine certain gold mineral properties and mining projects. The company holds a portfolio of 31 gold projects which cover areas with known gold occurrences, a history of mining and are prospective for high-grade epithermal gold mineralization.
