32 | ASIA Miner | Volume 14 • Issue 3 | 2017 Japan THE 2017 field exploration program is un- der way at the Hokkaido gold prospects of Irving Resources. The company is ex- ploring for high-grade epithermal precious metal vein mineralisation and initial efforts are focusing on the Omui mining conces- sion and prospecting licence applications with the aim of better understanding the mineralised system. Irving identified high-grade gold and sil- ver vein mineralisation at Omui through a first phase sampling program conducted shortly after acquiring the property. The new field program will include: • A detailed soil grid across the mining concession and surrounding areas looking for gold, silver and pathfinder element anomalism; • A close-spaced gravity and ground magnetics program to help identify po- tential mineralised faults; and • Various ground electrical surveys to better evaluate alteration and structure. Mitsui Mineral Development Engineer- ing Co Ltd (MINDECO) is conducting this work, which will take approximately three months. Data from these surveys will drive future drill targeting. Specialised stream sediment sampling using a technique called bulk leach extract- able gold (BLEG) is being conducted over the greater prospecting licence area. BLEG sampling produces highly sensitive results that can help identify new mineralized areas. Accompanying reconnaissance BLEG sam- pling, a team of Irving geologists is undertaking reconnaissance mapping and prospecting. This team has already identified several new areas of hot spring silica deposits, called sinter, and collected rock chip samples to determine if they are gold bearing. Irving plans similar prospecting activities at its Utanobori, Rubeshibe, Eniwa and Sado projects later this year. The company recently acquired the Eni- wa project, which encompasses areas in or around the historic Koryu and Eni- wa mines where high-grade epithermal gold-silver veins were exploited on a lim- ited basis. Irving filed applications for 20 mineral prospecting licences totaling 56.15sqkm covering a prospective area approximately 20km south of Sapporo. The Ministry of Economy, Trade and Industry (METI), Hok- kaido Bureau accepted all applications, and a multi-step review is under way. MIN- DECO is assisting Irving throughout the process. The Koryu and Eniwa mines closed abruptly in 1943 due to the Gold Mine Closure Act. Koryu mine saw brief periods of mining and exploration activity in the 1950s, 1960s and 1970-80s, but Eniwa remained closed. Irving holds five prospective precious metal projects in Japan, four on Hokkaido and one on Sado Island. SUMIKO Resources Exploration & Development Co Ltd (SRED) will manage and operate the Japanese drilling programs for Japan Gold Corp. To support the new contract, Japan Gold is purchasing three diamond core drill rigs, which will be operated by SRED. SRED, which is a subsidiary of major non-ferrous metal mining and smelting company Sumitomo Metal Mining Co Ltd, offers consulting services for resource exploration and environmental investigation using geological, geophysical exploration and related technologies, including drilling. SRED was instrumental in the prospecting, development and ex- ploitation of the Hishikari mine, Japan's largest and highest grade operating gold mine. The three portable rigs are being purchased from PT Promincon Indonesia (PMC) for US$544,000. PMC manufactures a range of portable diamond drill rigs and is an established diamond core drill- ing contracting company incorporated in Indonesia. Japan Gold believes acquisition of the two PMC400 drill rigs and one PMC700 drill rig will give it independence and flexibility on the timing and execution of its drill programs. In addition, it sees cost saving benefits of owning drill rigs. The compact nature of these diamond drill rigs allows for rap- id set-up, move and the remediation of drill sites. They also have a smaller environmental footprint when compared to conventional equipment. Japan Gold's chairman and CEO John Proust said, "We are very pleased to partner with SRED in this new venture. Their experience and reputation in Japan is unsurpassed and will be particularly valu- able as we seek to unlock the potential of our large project portfolio. Undoubtedly, this partnership will enhance the capability and credi- bility of Japan Gold Corp." Japan Gold has been granted 23 of its 56 prospecting rights li- cence applications over the Ikutahara Gold Project in Northern Hok- kaido. Granting of these rights authorises the company to com- mence more advanced exploration methods, including drilling. The 19,114-hectare Ikutahara project comprises 56 prospect- ing rights licence applications covering 16 historic gold mines and workings. Twenty-three applications, covering 8033 hectares, in- cluding the high priority Akebono target, have been granted. Detailed mapping and geochemical sampling completed at Iku- tahara in 2016 identified high priority targets for further testing. The company has lodged detailed drill plans to prepare drilling permits on high-priority targets.
