[{"type":"text","content":"VANCOUVER, British Columbia, Dec. 06, 2017 (GLOBE NEWSWIRE) -- Irving Resources Inc. (CSE:IRV) (“Irving” or the “Company”) is pleased to announce it has received a final report on gravity data collected at its 100%-controlled Omu high-grade gold-silver project, Hokkaido, Japan. The recently completed 2017 exploration program at Omu was undertaken by Mitsui Mineral Development Engineering Co., Ltd. (MINDECO) under the supervision of Irving personnel. Data from the 2017 program including stream sediment analyses by bulk leach extractable gold (BLEG) method, detailed soil grid analyses and drone-based magnetics will be reported in a series of news releases over the next few weeks as it becomes available. Irving’s 2017 field program was geared toward target generation in preparation for more advanced work including trenching and drilling in 2018. Gravity Data Reveals Structural Architecture of the Omu Project Property-wide gravity data was collected at Omu over a two-month period earlier this year. Gravity data help discern changes in sub-surface rock density and are particularly helpful in highlighting the structural framework of the subsurface. The Bouger Anomaly Map (1st Vertical Derivative) presented in Figure 1 shows a north-northeast trending corridor of anomalously low density transecting the property. Irving interprets this to reflect a structural graben, or rift, likely related to tectonism that accompanied volcanism and mineralization in this area. Similar oriented structural features are associated with other Au-Ag vein systems in the region including Konomai mine, the largest historic producer on Hokkaido (Sumitomo Metal Mining Corp. Ltd., 1915-1973, 2.35 Moz Au, 38.6 Moz Ag). Also evident are discrete areas of higher density underlying each of the three main mineralized occurrences, Omui Mine, Hokuryu Mine and the recently discovered Omu Sinter. In each case, these gravity highs may reflect areas where higher density basement sedimentary rocks are in closer proximity to surface. Identifying shallow basement highs was a critical component of exploration at the Hishikari Mine, Kyushu (Sumitomo Metal Mining Corp. Ltd., 1981-present, over 7 Moz Au), where veining focuses around basement domes. Notwithstanding the production from other properties in the region, there can be no assurance that an economic deposit w...
