- IKDD22-005 has confirmed continuity of the Shouei vein 100 m to the southwest of the historic workings with the next high-grade zone from inside a broader mineralized vein construction:
0.75 m @ 22.5 g/t Au & 41.3 g/t Ag from 276.0 m
- IKDD22-002: proved continuity of mineralization 50 m under the 2021 drill intercept from IKDD21-010 which intersected 20.0 m @ 6.3 g/t Au & 15.7 g/t Ag, giving the next important interval:
0.4 m @ 19. 0 g/t Au & 15.7 Ag from 280.95 m
(Incl. 0.2 m @ 34.6 g/t Au & 25.0 g/t Ag from 280.95 m)
- IKDD22-007: focused mineralization under IKDD21-008 which intersected the ultra-high-grade interval of 0.45 m @ 1,395 g/t Au & 768 g/t Ag. From roughly 200 m down gap IKDD22-007 encountered extremely silicified and altered hydrothermally brecciated rhyolite minimize by quite a few banded quartz veins. The drill gap stopped in mineralization effectively wanting its goal depth underneath tough drilling situations and as a result of a brief expiry of a neighborhood forestry allow, with the next important intervals:
1.1m @ 2.9 g/t Au & 11.7 g/t Ag from 266.8 m
(incl. 0.35 m @ 7.0 g/t Au @ 22.1 g/t Ag from 267.25 m
0.4 m @ 12.8 g/t Au & 35.3 g/t Ag from 288.4 m
(incl. 0.2 m @ 23.7 g/t Au & 74.7 g/t Ag from 288.6 m)
Andrew Rowe, Vice President Exploration said, “We’re very inspired by the latest findings on the Ryuo prospect. The mix of a number of high-grade vein constructions with high-level vein textures and a well-preserved alteration system helps deeper drilling, significantly alongside strike to the southwest of the prospect. We look ahead to finishing one other spherical of drill holes to check these ideas earlier than the top of this 12 months.”
Abstract of Findings at Ryuo and the Implications for Ongoing Exploration:
The 2022 drill program has considerably superior the understanding of geological controls and alteration zonation with respect to high-grade mineralization at Ryuo. Importantly, high-grade gold occasions have been recognized alongside the size of the prospect in a number of parallel vein zones, and alteration research show the system is effectively preserved.
IKDD22-005 has confirmed an extension of the Shouei vein mineralization 100 m to the southwest. Additional step out drilling is required to substantiate strike continuity to depth under veining intersected within the high of drill gap IKDD21-005, and in direction of the open high-grade mineralization intersected 400 m to the southwest in drill holes IKDD21-008 and IKDD22-007, (Determine 2 & 3).
IKDD22-007 focusing on the depth extension of the extremely high-grade vein in IKDD21-008 (0.45 m @ 1,395 g/t Au & 768 g/t Ag) terminated greater than 100 m earlier than goal depth underneath tough drilling situations and as a result of a brief expiry of a neighborhood forestry allow. From 200 m down-hole, intensely altered and hydrothermally brecciated rhyolite was drilled to the underside of the outlet at 289.4 m. Quite a few banded quartz veins minimize the brecciated rhyolite carrying anomalous gold alongside its size, with greater grade intervals together with the 40 cm vein from the underside of the outlet which gave 12.8 g/t Au & 35.5 g/t Ag with a high-grade included interval of 23.7g/t Au & 64.7 g/t Ag (Determine 4). This breccia zone was surprising and seems to be a part of a major, partially examined mineralized construction which subsequent drilling will goal as a precedence.
Hydrothermal alteration of the host rocks in low-sulphidation epithermal vein techniques create a definite zonal association of clay minerals. Smectite dominant assemblages type above and peripheral to quartz veining, whereas a mixed-layer (illite-smectite) assemblage kinds within the higher elements of the gold-bearing vein zone, this progresses downward right into a chlorite-illite dominant assemblage which coincides with the boiling-zone the place high-grade gold deposition happens. This affiliation of clay zonation and gold mineralization has been effectively documented in literature, together with on the Hishikari mine in Kyushu2.
The higher a part of this zonal association of clay alteration has been interpreted from spectral evaluation of drill core alongside the size of the Ryuo prospect. A smectite dominant zone is outlined above and adjoining to greater grade veins, and a mixed-layer zone is interpreted from an illite+smectite dominant assemblage, related to many of the high-grade veining seen up to now, (Figures 3 & 4). The deeper chlorite-illite assemblage has not but been acknowledged at Ryuo indicating the epithermal system is preserved and that the principle high-grade boiling zone lies at depth. Moreover, the smectite / mixed-layer interface at Ryuo deepens or plunges to the southwest of the prospect. Equally, the highest of the rhyolite dome advanced additionally lies deeper within the southwest of the alteration hall, (Determine 4). Ongoing drilling will concentrate on focusing on the deeper parts of the Ryuo hydrothermal system for high-grade mineralization related to within the chlorite-illite zone.
Ryuo Prospect
The Ryuo Prospect consists of 5 areas of workings; Jinja, Shouei, Taisei, Ryuei and Buryu that had been developed alongside a 1.2 km lengthy, open ended pattern of alteration and mineralization previous to the government-imposed closure in 1943 (Determine 2). Historic underground sampling within the Jinja vein workings revealed high-grade gold-silver mineralization together with ‘degree 4’ of the workings, which was sampled alongside a 72 m strike size giving a mean grade of 40.8 g/t Au and 193 g/t Ag, with a mean vein width roughly 0.5 m. Determine 3 illustrates a long-section of the Jinja vein workings with the underground sampling reported by the Steel Mining Company of Japan (MMAJ)1.
New Accepted Prospecting Rights Purposes on the Ikutahara Mission
Eleven new prospecting rights had been lodged to cowl potential Miocene volcanics instantly to the north and west of the Ryuo prospect to make sure protection of potential strike and parallel extension to the Ryuo mineralization. The brand new functions comprising a complete of two,567 hectares have now been accepted by the Ministry of Financial system Commerce and Trade (METI) Hokkaido, (Determine 1).
