VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 01/31/13 -- 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. The assay results include seven additional underground drill hole results from drilling at the Oracle Ridge Copper Mine, located in southern Arizona.

The assay results disclosed by the Corporation to date are consistent with historical data. 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. The Corporation is analyzing the samples for a full suite of elements and have identified silver and gold as potential by-products.

Surface drill hole ODH-044 encountered an interval of 47.2 feet of 2.21% copper, including within that interval 10.0 feet of 3.92% copper and 0.9 oz/ton silver. Underground drill hole OUH-07 encountered an interval of 47.0 feet of 2.07% copper, including within that interval 10.0 feet of 4.85% copper and 1.05 oz/ton silver.

Oracle Mining has posted an updated diagram of all drill hole locations of these reported assay results at http://www.oracleminingcorp.com/_resources/images/2013_January_skarn.pdf.

The following tabulates the intervals obtained from this phase of the drilling program:

The intervals were calculated using a 1.0% copper cut-off and may include internal waste to reflect a potential mineable width. 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 and 6 will be needed before true thickness can be estimated. Intervals labelled "includes" are higher-grade portions of the previous listed interval.

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) and 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 Corporation inserts one standard sample for every 20 samples of core and one blank sample for every 40 samples of core submitted to the assay laboratories. The Corporation inserts a blank sample for core for any submission with fewer than 40 samples. Oracle Mining periodically submits the pulps of the samples assayed by one laboratory to another independent laboratory for check analysis.
