CuOro To File Updated Technical Report and Clarifies Technical Disclosure

VANCOUVER, BRITISH COLUMBIA--(Marketwire - May 26, 2011) - CuOro Resources Corp. (TSX VENTURE:CUA.H) ("CuOro" or the "Company") announces today that as a result of a review by the British Columbia Securities Commission (the "BCSC"), CuOro is issuing the following news release to clarify its disclosure regarding its Santa Elena property.

Retraction of Historical Mineral Resource Estimates and Correction of Technical Disclosure Issues

In a March 28, 2011 technical report "Technical Report on the Santa Elena Project, Department of Antioquia, Colombia" (the "Previous Report") the Company referred to a historical mineral resource estimate in a manner not in compliance with the requirements of National Instrument 43-101 ("NI 43-101"). This non-compliant disclosure was subsequently replicated in the Company's continuous disclosure documents, including (a) the Company's annual information form for the year ended November 30, 2010 (the "AIF"); (b) its Management's Discussion & Analysis for the year ended November 30, 2010, in and for the three months ended February 28, 2011; (c) in a news release and material change report dated January 10, 2011; and (d) in corporate presentations and investor relations materials contained on the Company's website.

The Company cautions that there has been insufficient exploration to define a mineral resource and it is uncertain if further exploration will result in the target being delineated as a mineral resource. Because the currently available information on the Santa Elena property is inadequate to support the disclosure of mineral resources, any prior disclosure made by the Company indicating otherwise should be disregarded and should not be relied upon. The Company formally retracts all disclosure of historical resource estimates on the Santa Elena property, is removing all such disclosure from its website, and will re-file its AIF on SEDAR reflecting such changes.

In addition, certain disclosure of assay results was described by the BCSC as being selective and not providing the level of detail required under NI 43-101. Further, in certain cases, previously reported channel sample results did not represent the grade and true thickness of the entire exposed outcrop. This applies to a composite result disclosed in the Company's news releases dated April 28, 2011 and May 2, 2011, where channel samples were cut "perpendicular to stratigraphy" as well as "along strike" with most of the sampling "along strike". This composite channel result does not represent the grade and true thickness measured across the contacts of the TEM1 massive sulphide zone. It represents the parts of the mineralized outcrops accessible for sampling. The Company will be amending its Previous Report and is correcting its disclosure of assay results and investor materials are being updated to provide the full range of results.

New Technical Report Being Prepared

Further to the Company's news releases dated April 28, 2011 and May 2, 2011 disclosing additional exploration activity, the Company intends to prepare and file a new technical report (the "Updated Report") shortly to address other non-compliance issues identified by the BCSC. For example, the Previous Report: (i) described methods and assumptions deemed unsuitable for estimating a mineral resource, and disclosed a historical quantity which was largely based on geophysical anomalies rather than drill holes; (ii) disclosed an average grade over four deposits based on samples which were insufficient in number and distribution to represent average grade of the disclosed quantities; and (iii) estimated grade of resources at two deposits without sufficient sampling information on which to determine grade.

There will be no material differences between the recommendations and conclusions contained in the Previous Report and those in the Updated Report, however, because of the non-compliance issues described above, investors and shareholders should rely only on the Updated Report and are cautioned that they should not place undue reliance on the Previous Report.

In those instances where the Company has retracted, revised, clarified or updated previous disclosure, the Company advises readers not to rely on such statements as they may continue to be found in the public domain.

Michel Rowland, P.Geo. is the Qualified Person responsible for the accuracy of this news release in compliance with NI 43-101.

On Behalf of the Board of Directors of CuOro Resources Corp.
