Oracle Mining Intercepts 87.5 Feet of 2.3% Copper and 17.5 Feet of 5.8% Copper

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 05/15/12 -- Oracle Mining Corp. (TSX: OMN)(OTCQX: OMCCF) (PINKSHEETS: OMCCF) (FRANKFURT: OMC) ("Oracle Mining" or the "Corporation") is pleased to announce assay results of a new mineralized zone from its ongoing drilling program at the Oracle Ridge Copper Mine, located in southern Arizona.

Drill hole ODH-24 encountered an interval of 17.5 feet of 5.81% copper and ODH-27 encountered an interval of 26.0 feet of 3.27% copper. In addition, the Corporation believes ODH-26, with an interval of 87.5 feet of 2.32% copper, is important as it indicates a large-scale irregularity in the intrusive/carbonate contact. Abrupt changes in the orientation of the intrusive/carbonate contact have been seen in other areas that host major skarn bed mineralization.

The new target area was indicated based on mineralization that is exposed in the ramp connecting the 5900 and 6400 haulage ways. As there is no historic drilling recorded in this area, these intersections represent a new mineralized zone that is not included in the historic resource base. The following tabulates the intervals obtained from this phase of the drilling program:

The intervals were calculated using an external 1.0% copper cut-off and may include internal waste to reflect a potential mineable width. True widths of drilling done to date will need to be modelled but are estimated to be 70% to 100% of the stated interval length. Intervals labelled "includes" are higher-grade portions of the previous listed interval.

The results encountered in Holes ODH-24, ODH-26 and ODH-27 continue to reinforce the Corporation's belief that the undrilled portions of the property have significant potential to host additional +1.0% copper mineralization. These holes were drilled as part of the Corporation's ongoing historic data base confirmation program. The successful completion of the validation drilling program will allow the Corporation to undertake a National Instrument 43-101 compliant resource estimation.

A total of 32 holes have been assayed and disclosed since Oracle Mining began its current drill program in early 2011. The assay results to date are consistent with historic data. The Corporation is analyzing the samples for a full suite of elements and have identified silver and gold as likely by-products that could provide additional project economic value.

Oracle Mining operates a rigorous QA/QC protocol on all aspects of sampling and analytical procedure. Drill core is checked, logged, marked for sampling and sawn in half. One-half of each drill core is maintained for future reference and one-half of each drill core is sent for analysis. Half-core samples are shipped to Skyline Assayer and Laboratories ("Skyline"), an accredited laboratory in Tucson, Arizona, which is contracted to complete all sample preparation and assaying. Samples are analyzed employing the appropriate methodology for analyses of copper, as well as fire assaying for silver and gold. For QA/QC purposes, Skyline runs a series of standard and blank samples and provides the results of these assays to us. Oracle Mining periodically submit the pulps of the samples assayed by Skyline to Chemex in Reno, Nevada for check analysis.
