Oracle Mining Announces Updated NI 43-101 Resource Estimate for the Oracle Ridge Copper Project

7.3 Million Tons Grading 1.88% Copper Equivalent Measured and Indicated and 5.6 Million Tons Grading 1.75% Copper Equivalent Inferred; Additional Assays

VANCOUVER, BRITISH COLUMBIA -- (Marketwired) -- 02/26/14 -- Oracle Mining Corp. ("Oracle Mining" or the "Corporation") (TSX: OMN)(FRANKFURT: OMC) announces an updated Measured and Indicated and Inferred Mineral Resource estimate in accordance with National Instrument 43-101 ("NI 43-101"), along with additional assay results from its recent underground drilling program, for its Oracle Ridge copper project ("Oracle Ridge" or "Oracle Ridge Project"), located 24 km northeast of Tucson, AZ.

Highlights:

At a 1.0% copper equivalent (CuEQ) cut-off grade, the updated Mineral Resource estimate for Oracle Ridge in accordance with NI 43-101, is:


--  7.3 million tons grading 1.88% CuEQ, 1.61% copper and 0.52 silver
    ounces/ton in the Measured and Indicated mineral resource category
    containing 236 million pounds of copper, and 3.8 million ounces of
    silver.

--  5.6 million tons grading 1.75% CuEQ, 1.53% copper and 0.49 silver
    ounces/ton in the Inferred mineral resource category containing 173
    million pounds of copper and 2.8 million ounces of silver.

The Corporation announced its initial Mineral Resource estimate for Oracle Ridge in March 2013, which was included in a technical report filed April 1, 2013 (the "2013 Technical Report"). We subsequently conducted an underground drill program in the summer of 2013. The results of the 2013 drill program are incorporated into the updated Mineral Resource estimate and intercepts from that drill program are reported in this news release.

As recommended in the 2013 Technical Report, Oracle Mining initiated a program of twinning historical holes and re-assaying historical core. Eleven holes were twinned and 66 historical holes were re-logged, photographed, resampled and submitted to Skyline Assayer and Laboratories for analysis. An analysis of core samples between historical and re-assays identified a bias of 12.5% in the copper grade. Consequently, all historical assay data were adjusted downward by 12.5%. Additionally, new drilling results obtained since the Oracle Ridge Project was acquired in 2010 have been consistently lower than the historical grades, resulting in lowering the overall average grade of the deposit. The new drilling information, the adjustment to historical drilling, along with other adjustments to the mineral resource estimation process have resulted in the loss of tons and overall lower grade compared to the March 2013 Mineral Resource estimate.

"The process undertaken in this Mineral Resource update has been thorough and provides management with increased confidence in the new Mineral Resource estimate," said Mr. Kevin Drover, Oracle Mining's CEO. "We believe the updated Mineral Resource estimate will allow management to better understand and evaluate the steps that will be necessary to advance the Project and we will provide shareholders with an update in the near future."

Updated Mineral Resource Estimate

In November 2013, Oracle Mining contracted ARSENEAU Consulting Services to prepare a Mineral Resource estimate in accordance with NI 43-101 for the Oracle Ridge Project.

Table 1 summarizes the combined estimated Measured and Indicated Mineral Resources at various cut-off grades for comparison purposes, with 1.0% CuEQ used as the base case cut-off grade. Measured plus Indicated Mineral Resources at the 1.0% CuEQ base case cut-off grade are estimated to be 7.3 million short tons at 1.61% copper. All tonnages in this news release are in imperial (short) tons.

--  Mineral Resources are not Mineral Reserves and do not have demonstrated
    economic viability. There is no certainty that all or any part of the
    Mineral Resources will be converted into Mineral Reserves.
--  The base case cut-off grade of 1.0% CuEQ has been estimated to ensure

--  Mineral Resource tonnage and contained metal have been rounded to
    reflect the accuracy of the estimate, and numbers may not add due to
    rounding.
--  Silver and gold grade estimates were based on a less comprehensive data
    set than the copper grade estimates. Where copper grade estimates exist
    without accompanying silver or gold grade estimates, the drill hole was
    not used to estimate the silver or gold grade.
--  Copper equivalency has been estimated using metal pricing of $2.80 per
    pound of copper, $20 per ounce of silver and $1,300 per ounce of gold.
    Metallurgical recovery were derived from preliminary lock cycle test
    results and assumed to be 81% for gold and silver. The formula used is
    as follows: CuEQ = Cu% + ((Ag oz/t x $20 x 0.81) + (Au oz/t x $1,300 x
    0.81))/$2.80/2,000 x 100.

    Mineral Resources will ever be upgraded to a higher category.

The Mineral Resource model was developed using a total of 613 drill holes, including 128 holes (70 from surface and 58 from underground) drilled on behalf of Oracle Mining between 2011 and 2013 drilling campaigns and 485 historical drill holes. All copper grades from the historical drill holes were adjusted down by 12.5% to correct an apparent bias associated with the historical assay database identified as a result of the 2013 re-assaying program of historical drill core.

The Mineral Resource estimate has been generated from drill hole sample assay results and the interpretation of a geologic model that relates to the spatial distribution of copper in the deposit. Grade was estimated by ordinary kriging constrained within individually identified geological beds using sample data composited to 10-foot intervals into model blocks measuring 15 by 15 by 10 feet vertically. High grades, greater than 10% copper and greater than 2.0 oz/t silver, were restricted to search radii of 20 by 20 by 20 feet. A comprehensive geological model that encompasses all known mineralization was constructed. Resources have been classified using average distances and a minimum number of drill holes within the search ellipse and are reported according to the CIM definition standards for Mineral Resources and Mineral Reserves.

Dr. Arseneau has verified the technical and scientific information including sampling, analytical and test data underlying the information or opinions relating to the updated Mineral Resource estimate included in this news release. This verification was done during visits to the Oracle Ridge Project site and by reviewing and interpreting the data that was produced.

There are no known legal, political, environmental, or other risks that could materially affect the potential development of the Mineral Resources.

A technical report supporting this disclosure will be filed under the Corporation's profile on SEDAR (www.sedar.com) on or before the filing of the Corporation's annual information form for the year ended December 31, 2013.

Oracle Mining has posted an updated diagram of all drill hole locations of these reported assay results at http://www.oracleminingcorp.com/_resources/images/2014_February_skarn.pdf.

The drilling intervals were calculated using a 1.0% copper cut-off grade and may include internal waste and accordingly are not representative of the true width of mineralized intercepts. The mineralized intercepts have been used in the model for the Mineral Resource Estimate. As the holes cut the mineralization at different angles, they all have different true widths. In general, they 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. There are no known drilling, recovery or other factors that could materially affect the accuracy or reliability of the data.

Data Verification

The Corporation maintains 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. The sample size varies depending on the geology and the mineralization. In general, the samples are predominantly about 5 feet long. One-half of each drill core is maintained for future reference and one-half of each drill core is sent for analysis. During 2013, half-core samples were shipped to Skyline Assayer and Laboratories ("Skyline"), in Tucson, Arizona, an ISO/IEC 17025 accredited laboratory. Skyline is contracted to complete all sample preparation and assaying and is independent of Oracle Mining. Samples are analyzed employing acid digestion and Atomic Absorption for analyses of copper, as well as fire assaying for silver and gold. For QA/QC purposes, Oracle Mining inserts standard reference materials and blank samples into each sample batch submitted for assay to monitor laboratory performance. The Corporation periodically submits the pulps of the samples assayed by its primary lab to ALS Chemex Labs Ltd. in Reno, Nevada for check analysis.

Dr. Gilles Arseneau has verified the technical and scientific information including sampling, analytical and test data underlying the 2013 drilling program assay results. Verification included QA/QC procedures review, inspection of drill core and review of assay certificates. This verification was done during a visit to the Oracle Ridge site and by reviewing and interpreting the data that was produced.
