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 surrounding 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 Development 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 sampling 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.
