MONTREAL, April 7, 2005 (PRIMEZONE) -- The O.T. Mining Corporation (PinkSheets:OTMN) ("O.T.") is pleased to announce the results of check assays on 11 mineralized core samples from drill hole NA04-6. These repeat assays were undertaken to assess the quality of assay data received from SGS Minerals Services in Toronto, Ontario, Canada and to assess two additional assay methods. A compilation of Quantech Titan 24 (2004) and Anaconda Company (1968) geophysical survey results from the Ruby Property has been completed.
O.T. drilled vertical core hole NA04-6 in the North Anomaly target area and intersected altered and mineralized Boulder Batholith, host to world-class mineralization at the "Richest Hill on Earth", located 14 miles to the south in Butte. The mineralization formed a continuous zone between 587 feet and 1,916 feet for an interval of 1,329 feet and consists of disseminations, veins, and replacements of pyrite, chalcopyrite, and molybdenite. The rocks that host this mineralization contain both phyllic and potassic alteration, typical of porphyry copper deposits. O.T. will re-enter the hole and determine the total depth of the mineralized zone in 2005. 18,000 feet of drilling has been contracted for this year.
The comparative results of the three assay methods are summarized in Table 1. The results indicate good agreement between the three techniques and document maximum copper values of one half of one percent (0.4975%) copper and 0.0363% molybdenum. The presence of a significant copper and molybdenum-bearing mineralizing system in O.T.'s drill hole NA04-6 is substantiated. This check assay program underscores the important point that future assays undertaken by SGS Minerals Services for O.T. will be accurate and precise, a prerequisite for successful exploration.

A review of geophysical survey results ("induced polarization" or "I.P.") undertaken by Quantech Geosciences under contract to O.T. in 2004 and by the Anaconda Company in 1968 indicates the geophysical signature of the interpreted porphyry copper mineralized zone on the Ruby Property is considerably larger than initially determined. Combining the results from both geophysical surveys indicate the target has an approximate length of 15,000 feet in an east-west direction and 8,000 feet north-south. This anomaly has been encompassed by recent O.T. claim staking and will be one of the significant targets that O.T. will explore on the Ruby Property in 2005 utilizing geological mapping, Mobile Metal Ions soil geochemistry and I.P. geophysical surveys.
