MONTREAL, Aug. 25, 2005 (PRIMEZONE) -- The O.T. Mining Corporation ("O.T.") (Pink Sheets:OTMN) is pleased to announce that considerable progress has been made on the exploration program at its 10.3 square mile Ruby Property in Montana. This aggressive exploration program was previously announced, and consists of integrated geology, geochemistry, geophysics and diamond drilling.
Geochemical and geophysical grid surveying and line cutting was completed on the Ruby West-Ruby Mine and the North Anomaly target areas. These grid lines are being used for the collection of the soil samples and geophysical data described below.
Mobile Metal Ion (MMI) soil sampling is 80% complete. To date, a total of 2,730 samples have been collected from the North Anomaly. The sampling is designed to test this target area for vein-type gold and silver mineralization as well as porphyry-type copper-molybdenum. The MMI technique has been successfully used on the property in the past, and was responsible for siting 2004 core hole NA04-6 that encountered porphyry copper mineralization (described below).
Induced polarization geophysical data are also being collected. The proprietary method used, Quantitative Section Induced Polarization, was developed and is operated by Matrix GeoTechnologies Ltd. of Toronto. Data are being collected from the Ruby West-Ruby Mine and the North Anomaly target areas.
Phase one of the Ruby West-Ruby Mine geophysical survey is complete. The results indicate the presence of two groups of strong geophysical responses. One of these is related to the past-producing high-grade gold and silver Ruby Mine and the second to a north-trending feature that crosscuts the Ruby Mine. Both sets of anomalies will be assessed by Phase two of the geophysical surveys ("Quantitative Section") and results integrated with MMI soil geochemistry to define drill targets for testing this year.
Drill testing of geological targets in and around the Ruby Mine is progressing. Two core holes totaling 2168' have been finished and a third hole is nearing completion. The 2 completed holes successfully intersected the Ruby structure, host to high-grade gold and silver mineralization. Core has been logged and sampled and shipped to SGS Mineral Services (Toronto) for assay. Results will be reported upon receipt of the assay data.
A second drill rig has been mobilized to deepen 2004 hole NA04-6. As previously announced, this hole encountered 1,329 feet of continuous porphyry copper mineralization in phyllic and potassic altered porphyry. The host rocks have been identified as the Boulder Batholith, host to the world-class porphyry copper/molybdenum mineralization at nearby Butte, Montana. The hole has been reentered, and will be drilling deeper portions of the porphyry system shortly.
Necessary permits continue to be obtained from state and federal agencies. O.T. received an amended Plan of Operations and approval for 7 new drill sites and associated roads from the U.S. Forest Service. The Department of Environmental Quality also approved an additional drill hole in the Ruby Mine area.
