TSX.V: TU

VANCOUVER, Sept. 2 /PRNewswire-FirstCall/ - Tigris Uranium Corp. (TSX.V: TU) ("Tigris" or the" Company") is pleased to announce that it has received final approval of its qualifying transaction (the "Transaction") by the TSX Venture Exchange ("TSX-V") and has commenced trading as a Tier 2 Mining Issuer on the TSX-V. In connection with the Transaction, the Company has changed its name from "Dauntless Capital Corp." to "Tigris Uranium Corp.". The new trading symbol of the Company is "TU".

The Transaction was initially announced in the Company's news release on May 27, 2010, and more particularly described in a news release of August 23, 2010 and filing statement dated August 18, 2010 (the "Filing Statement"). As a result of the completion of the Transaction, the Company has ceased to be a Capital Pool Company (as defined in the policies of the TSX-V).

The Company completed the Transaction through the acquisition of an exclusive option (the "Option") to earn interests in the Crownpoint, Hosta Butte and McKinley uranium properties located in McKinley County, New Mexico, USA, subject to a sliding scale gross proceeds royalty. The Option was granted to the Company by NZ Uranium, LLC of Arizona.

In May 2010, Tigris received three technical reports for the Crownpoint Properties (Sections 19 and 29, and Section 24) as well as the Hosta Butte Property. The reports were prepared by Gregory Myers Ph.D., a Member and Chartered Professional Geologist of the Australian Institute of Mining and Metallurgy and a Washington State Professional Geologist.

All three properties are located in Northwestern New Mexico, approximately 125 miles northwest of Albuquerque and approximately 5 miles to the south of the small town of Crownpoint. Uranium mineralization at the properties is hosted in sandstone beds of the Westwater Canyon Member of the Morrison Formation. The mineralization represents secondarily enriched uranium bodies which are controlled by porous and permeable stratigraphic units and structural zones and is amenable to in situ leach (ISL) technology.

The resource estimations for the Crownpoint and Hosta Butte properties, which are outlined in the technical reports, have been prepared to meet National Instruments 43-101 standards and are summarized in Table 1, 2, and 3.

The Crownpoint Section 24 resource estimation was calculated using 157 drillholes (316,750 feet) drilled by Conoco in 1976 and 1979.

The Hosta Butte Resource was calculated using 133 drillholes (324,285 feet) drilled by Conoco in 1976 and 1980.

Notes:

(1) The grade of the mineralized zone was calculated as an average, bench by bench, and did not utilize any weighting factors in the calculations. The calculated grade utilized the average grade of the 10 foot bench composite and includes 0.5 foot intervals below the 0.04% cutoff grade causing dilution of the grade average. The pounds of eU(3)O(8) for each bench were tabulated along with the area and calculated volume for each bench. Cross sections with drill hole eU(3)O(8)% values were generated in the Rockworks 2004 software program and the cross sections were then interpreted by hand on a section by section basis. The sectional data was transferred to bench plans, spaced every 10 feet, and the ore zones were interpreted and digitized in order to accurately measure the area of the mineralized body outline. The measured area and volumes calculated from the benches were used to calculate the tons contained on each bench.

(2) The dry density value of 15.8 ft(3)/ton was used for mineralized sandstone in this report.

(3) Radiometric logging of the drill holes was completed by Conoco, and the logs were examined by Greg Myers. Natural gamma (counts/second, or cps), self potential (millivolts), and resistance (ohms) were recorded at 1/2 foot increments on magnetic tape and then processed by computer to graphically reproducible form. The eU(3)O(8) % conversions from the gamma log data were calculated using the raw natural gamma counts multiplied by the K-factor times 2 (eU(3)O(8) % = (gamma cps) x (K-factor x 10-5) x (2)). A typical K-factor reported on a Hosta Butte log is 2.45 and the 10-5 factor is not included on the log header, therefore the corrected K factor would be 0.0000245.

Mineral Resources are not Mineral Reserves and do not have a demonstrated economic viability.

About Tigris Uranium Corp.

Tigris Uranium Corp. has assembled an elite staff and technical team with considerable experience in the uranium sector and is committed to providing shareholders with exceptional leverage to rising uranium prices through the acquisition of established resources. Tigris will achieve this through four value-enhancing strategies: acquisition of uranium projects with established resources in stable mining jurisdictions such as the United States and Canada; conducting geological and engineering work likely to expand resources, upgrade resources to reserves and improve recoverability; advancing existing resources into and through the permitting process to accelerate the potential uranium production timeline; and selling or partnering projects when they reach the production stage, to limit risk and share dilution.
