32 | ASIA Miner | Volume 14 • Issue 4 | 2017 Japan IRVING Resources has received high-grade gold and silver grade assays from surface samples at the Omu Gold-Silver Project in Hokkaido. Samples have come from the Omui mine site and sur- rounding areas, and have returned up to 203 g/t gold and 5310 g/t silver. Detailed soil sampling has been carried out on a 50x50 metre staggered grid. While extracting samples pieces of mineralised rock float are sometimes encountered and sampled. At Honpi (Main Vein) prospect recent rock float samples have returned 186.5 g/t gold and 353 g/t silver, 11.75 g/t gold and 71.1 g/t silver, 6.77 g/t gold and 33.3 g/t silver, and 5.27 g/t gold and 177 g/t silver. In addition, a new vein was encountered in a hand dug trench and a chip channel sample returned the 203 g/t gold and 5310 g/t silver intersection over a true width of 0.8 metres. Exploration at Omu is being undertaken by Mitsui Mineral Devel- opment Engineering Co Ltd (MINDECO) under the supervision of Irving personnel. Irving believes mineralised float material is derived from underlying weathered bedrock and that these new results indicate potential for multiple sub-parallel east-west trending veins across a 200-metre wide corridor surrounding Honpi. At Nanko prospect, rock float samples have greatly expanded the area of known mineralisation. Notable samples include 691 g/t gold and 515 g/t silver, 42.5 g/t gold and 539 g/t silver, 3.98 g/t gold and 3.92 g/t silver in areas south of Nanko. Northeast of Nanko, notable samples include 39.3 g/t gold and 20.2 g/t silver, 16.55 g/t gold and 40.9 g/t silver, and 7.09 g/t gold and 10 g/t silver. A detailed gravity survey has recently been completed and data is being processed while a detailed drone-based magnetic survey is due to be completed by the end of October. Data collected during the 2017 program will be used to develop a drill program at Omu in 2018. Across the greater Omu gold project area, stream sediment sam- pling has been completed. A total of 100 bulk leach extractable gold (BLEG) samples, specialised samples consisting of fine silt and clay, have been collected and shipped to ALS Global in Vancouver for analysis. JAPAN Gold has expanded its epithermal gold exploration portfolio with the addition of three new projects in the prospective Kitami Metallogenic Province of north Hokkaido. The Onne, Fujimi and Ha- rutomi projects cover historic gold-silver and mercury mines in a prospective and largely underexplored area south of the company's Ikutahara project. The three projects comprising 21 applications and 6871 hectares collectively, have been accepted by the Ministry of Economy, Trade and Industry (METI). The company now holds priority over these areas and is authorised to commence surface exploration. With the addition of these new projects Japan Gold's portfolio now comprises 66,477 hectares over 15 separate projects on the three main islands of Japan. Onne comprises nine application blocks for 2998 hectares and hosts the historic Onne gold-silver and Niko mercury mines. Fu- jimi comprises seven application blocks for 2201 hectares over the historic Fujimi and No 2 Tateushi gold-silver mines and surrounds. Harutomi, centred on the historic Harutomi mine, consists of five application blocks for 1672 hectares. The projects are in the southern part of the Monbetsu-Rubeshi- be Graben, one of two major graben features that localise miner- alisation within Kitami Metallogenic Province. The projects lie along a 40km-long structural corridor which cuts across the southern part of the graben and hosts more than 15 historically developed gold-silver and mercury mines, and workings. Previous studies indicate the gold and mercury mineralisation are genetically related to the same hydrothermal activity. Work completed by the Metal Mining Agency of Japan between 1989 and 91 included drilling beneath the Oketo mercury mine, south of the Onne project, and intersected narrow-weakly mineralised quartz veining. Japan Gold is looking to further explore the potential link between mercury anomalism and epithermal gold mineralisation in this un- derexplored district. The company will seek to define the limits of the alteration systems around these historically mined vein systems and use surface mapping and geochemistry to target new zones and extensions to previously exploited vein zones for scout drill testing. Japan Gold's chairman and CEO John Proust said, "These gold districts offer excellent exploration opportunities for potential new discoveries due to their relatively under-explored nature."
