Oracle Mining Announces First Assays From Underground Drilling Program: Recent Drilling Intercepts 94.0 Feet of 2.02% Copper, Including 20.0 Feet of 4.7% Copper06:00 EDT Wednesday, September 12, 2012VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 12, 2012) - Oracle Mining Corp. (TSX:OMN)(OTCQX:OMCCF)(FRANKFURT:OMC) ("Oracle Mining" or the "Corporation") is pleased to announce assay results from its ongoing core drilling program. These assay results include Oracle Mining's first underground drill hole and the first results from drilling on the Zone 5 mineralization at the Oracle Ridge Copper Mine, located in southern Arizona.Underground drill hole OUH-01 encountered an interval of 94.0 feet of 2.02% copper, including within that interval 60.0 feet of 2.59% copper containing 20.0 feet of 4.7% copper. OUH-01 is the first hole drilled from an underground drill station by Oracle Mining and these results are the first from the Zone 5 mineralization.

True widths of mineralized intercepts completed to date will need to be modelled but are estimated to be 60% to 100% of the stated interval length for Zones 1, 2 and 4. Additional drilling in Zones 5, 6 and the "PD" target will be needed before true thickness can be estimated. Intervals labelled "includes" are higher-grade portions of the previous listed interval.These holes were drilled as part of Oracle Mining's ongoing drilling program, the results of which will be included in a National Instrument 43-101 ("NI 43-101") compliant resource estimation to be completed in 2012. A total of 42 holes have been assayed and reported since Oracle Mining began its current drill program in early 2011. The assay results are consistent with historical data. The Corporation is analyzing the samples for a full suite of additional elements and have identified silver and gold as likely by-products that could provide additional project economic value.Oracle Mining employs a rigorous QA/QC protocol on all aspects of sampling and analytical procedure. Drill core is checked, logged, marked for sampling and split in half. One-half of each drill core is maintained for future reference and the other half of each drill core is sent for analysis. Half-core samples are shipped to accredited laboratories contracted to complete all sample preparation and assaying, including Skyline Assayer and Laboratories (Tucson), SGS Minerals Services (Elko/Vancouver) or ALS Chemex Labs Ltd. (Reno/Vancouver). Samples are analyzed employing the appropriate methodology for analyses of copper, as well as fire assaying for silver and gold. For QA/QC purposes, the assay laboratories run a series of standard and blank samples and provide the results of these assays to the Corporation. Oracle Mining periodically submits the pulps of the samples assayed by one laboratory to another independent laboratory for check analysis.Oracle Mining has posted an updated diagram of drilled holes with reported assay results at http://www.oracleminingcorp.com/properties/.The technical information in this media release has been prepared in accordance with Canadian regulatory requirements set out in NI 43-101 and reviewed by Glenn R.
