Irving Resources has encountered high-grade gold-silver (Au-Ag) assays from an expedited batch of diamond drill samples at Omu Sinter (Otoineppu Mine).
“We are delighted with these first results from hole 19OMS-002,” commented Akiko Levinson, President, CEO and director of Irving Resources.
“We now see that Omu Sinter has the potential to host high-grade gold and silver like other nearby targets, Omui mine and Hokuryu mine, on our extensive Omu project. Our success at Omu Sinter is a result of the collective efforts of our entire team in Japan. Everyone, including many in the local community of Omu, played a critical role in making this happen.”
“Confirmation of the high-grade potential of Omu Sinter is very encouraging,” commented Dr. Quinton Hennigh, director of and technical advisor to Irving Resources. “We already appear to have intersected a significant feeder vein within this robust hot spring system. The bulk of the productive boiling zone, the part of the system where high-grade mineralisation is typically deposited, remains untested beneath. Other intervals of vein are evident in the remaining 150 m-long mineralised interval encountered in hole 19OMS-002. We eagerly await further assays.”
“Attributes of this newly encountered mineralisation suggest it is closely linked with our other targets across the Omu property,” continued Dr. Hennigh. “It displays a silver-to-gold ratio of between 10-1 and 20-1 in line with what we see elsewhere. Pathfinder elements, while elevated, are not especially high and display similar level to other gold vein deposits on the property. High grades of Au and Ag are associated with ginguro similar to that seen in veins at Omui and Hokuryu mines. Omu Sinter is clearly structurally linked to the other high-grade gold-silver occurrences. This evidence suggests that we potentially have an extensive gold system across our approximately 168.29 sq km property.”
These are the first assays from Irving’s current 2019 drill program at Omu and were expedited to ALS Global Laboratory, Vancouver, Canada, for rush assay to provide Irving with an early indication of the precious metal content of this important zone. Samples from the lower part of hole 19OMS-002 (189.5-421.2 metre, end of hole) are being shipped to ALS Global Laboratory, Brisbane, Australia. Assays from these samples are expected within the next few weeks.
Omu Sinter was first recognised by Irving as a prospective target in 2016. Irving geologists noted that many homes in the area had rock gardens displaying large boulders of silica sinter, material formed by hot spring waters as they emerge from the ground and flow into shallow pools. Upon enquiring about the origin of such boulders, local people pointed Irving personnel to a bluff where they were quarried. Rock chip sampling proved the sinter was strongly anomalous in Au, Ag and pathfinder elements. Geophysical data, magnetic and gravity, collected by Irving indicated a larger structure is present under the area and is associated with extensive hydrothermal alteration. Irving’s 2019 diamond drill program is the first drilling to be undertaken at this greenfield target. Irving considers these early results as confirmation that feeder veins for the Omu Sinter have the potential to host high-grade Au-Ag mineralisation.
Hole 19OMS-001 will be split and sampled following hole 19OMS-002. A third hole, 19OMS-003, is currently underway. It is collared from the same pad as 19OMS-002, but oriented south-southeast at an inclination of 55 degrees. Hole 19OMS-003 is designed to intersect the same mineralised zone as hole 19OMS-002, but also test a possible E-W oriented cross structure evident in geophysical data.
