Tigris to clarify Technical Disclosures related to Crownpoint and Hosta Butte Technical Reports

As a result of a review by the British Columbia Securities Commission, we are issuing the following news release to clarify our disclosure

TSX.V:TU

VANCOUVER, Dec. 28, 2011 /CNW/ - Tigris Uranium Corp. (TSX.V: TU) ("the Company") announces that, as a result of a technical disclosure review by the British Columbia Securities Commission (the "BCSC"), clarifications are required regarding current uranium resource estimates in the Technical Reports on the Company's Crownpoint Section 19/29 Property dated June 20, 2011 and its Crownpoint Section 24 and Hosta Butte Properties dated May 26, 2010 (collectively, the "Reports").

As a result, the Company provisionally retracts current resource estimates in the Reports pending the preparation and filing of new, independent technical reports, and provides information about the comparable historical reserve estimates in a following Table. The current mineral resource estimates for the Crownpoint Section 19, 24, and 29 and Hosta Butte properties are not supported by compliant NI 43-101 technical reports, contrary to NI 43-101, and the current resources should not be relied on until they have been independently verified and supported by new or amended technical reports.

Because of limitations in the database available to the report author, the Reports do not contain sufficient verifiable data and information to support current resource estimates.

The resource estimates contained in the Reports were based upon data collected by Conoco during the 1970s and which included in excess of 74,374 ½ ft original gamma probe readings.   This data was included in a historical pre-feasibility study prepared by Conoco.  The BCSC has advised the Company that reliance on historic data, information, and reports is contrary to the verification requirements of NI 43-101, and is not in itself sufficient to verify prior gamma values, disequilibrium factors, and other information used by the Reports to estimate current resources.

The BCSC has not questioned the validity of the data collected by Conoco.  The BCSC has however, questioned the steps taken by the Report's author to verify the above data.

The Company is working closely with the BCSC to correct the identified deficiencies and to ensure that it becomes fully compliant as soon as possible.  The Company will be retaining a new QP to prepare the new reports.

Notwithstanding the provisional retraction of the current resource estimates contained in the Reports, pending the preparation and filing of new, independent technical reports the Company reiterates the following historical reserve estimates contained in the Reports, with a comparison to the retracted current estimates:

Conoco reported the above as "mineral reserves" which do not meet the Proven or Probable Reserve definition stated in NI 43-101 but are likely comparable to the inferred or indicated resource classifications.  The historical estimates should not be relied upon but are considered to be relevant. The "reserves" were estimated by compiling the grade times thickness values in drill holes for each mineralized horizon and then contouring the values on a plan map. The mineralized zones were compiled on plan maps and the bodies were interpreted to form linear zones controlled by paleo river channels. The mineralized bodies were extended between barren drill holes in order to expand the body to the next mineralized drill hole. The volume of the interpreted body was multiplied by the grade times thickness product to give the pounds of contained eU₃O₈. Mineralization cross-sections are not included in the data base and detailed documentation of the Conoco "reserve" is not contained in the database files. Discussions of "reserve" estimation procedures with the Conoco project geologist confirm an accepted and reliable estimation procedure was followed.  In order to upgrade the historical estimates by Conoco as current mineral resources the Company needs to carry out additional work which may include but not be limited to verification drilling/logging, chemical assays, historical log analysis, historical instrumentation information, and analysis and review of property drill core archived at the USGS.  The Company anticipates completing the additional work and preparing and filing new reports in the first quarter of next year.

Readers are cautioned that a qualified person has not done sufficient work to classify the historical estimate as current mineral resources and that the Company is not treating the historical estimates as current mineral resources.

The technical content of this news release has been reviewed and approved by the Company's Chief Geologist, Douglas Underhill, PhD, MSc, MBA , a Qualified Person as defined by National Instrument 43-101.
