65 Queen Street West Suite 825, P.O. Box 75 Toronto, Ontario M5H 2M5 Canada CROCODILE GOLD ANNOUNCES INITIAL URANIUM RESOURCE ESTIMATE AT THUNDERBALL COMPLETED BY JV PARTNER THUNDELARRA February 8, 2011 Crocodile Gold Corp. (TSX:CRK) (OTCQX:CROCF) (Frankfurt:XGC) ( Crocodile Gold or the Company ) is pleased to announce an initial JORC compliant mineral resource estimate completed by its joint venture partner, Thundelarra Exploration Ltd ( Thundelarra ) on the Thunderball uranium prospect located within the Hayes Creek Project located approximately 140 kilometres south of Darwin in the Northern Territory of Australia. The mineral resource estimate was completed by SRK Consulting. The resource estimate is based upon chemical assay data from 16 diamond and 39 reverse circulation drill holes completed at Thunderball since the deposit was discovered by Thundelarra in late 2008. All drill sample data was aggregated into four metree composites prior to modeling. All dataa composites with a grade above 0.40 % U 3 O 8 were cut to that level. Resource estimates were then calculated at lower cut-offf grades of 0.02% U 3 O 8 and 0.04% U 3 O 8 for each of the two parallel zones of mineralization, as presented in Table 1 below. Table 1: Thunderball Uranium Deposit Inferred Resource Estimate (JORC compliant) 0.02% U 3 O 8 Cut Off Grade 0. 04% U 3 O 8 Cut Off Grade Tonnes Contained Contained Grade Grade Metal Tonnes Metal (% U 3 O 8 ) (% U (pounds U 3 3O 8 ) 3 O 8 ) (pounds U 3 O 8 ) Lower Zone Upper Zone Total Inferred Resource 848,0000 207,0000 1,056,000 0.0907 0.0343 0.0796 1,696,000 157,0000 1,853,000 795,000 34,0000 829,000 0.0945 0.0434 0.0924 1,656,000 33,0000 1,689,000 The Thunderball prospect has returned a number of high grade drill intercepts to date, however the current drill hole spacing is considered to be insufficient to prove continuity of this high grade mineralization. Consequently, a cautious approach has been taken to the classification of the resource and a top cut applied to limit the influence of the high grade intercepts. The 0.40 % U 3 O 8 top cut affected five data composites that had uncut average grades of up to 7.6% U 3 O 8 and disproportionally increased contained metal by 200%. The uncut model comprises 775,000 tonnes at an average grade of 0.3196% U 3 O 8 for 5.5 million pounds of U 3 O 8 (0.04% U 3 O 8 lower cut). Geological modeling associated with the resource estimation has highlighted the potential to identify repetitions of the existing mineralized zones at Thunderball. In particular the contact between the Gerowie Tuff and Zamu Dolerite, approximately 70 metres stratigraphically below the Lower Zone resource, is considered a priority target. The declaration of an inaugural resource at Thunderball is an important milestone in the development of Thundelarra s Hayes Creek Uranium Project. Five prospects at Hayes Creek have now returned significant drill intercepts and Thundelarra has stated that in 2011 it will focus drilling on these targets with the aim of upgrading one or more to resource status. Drilling will also be carried out at Thunderball to test for repetitions of mineralization at depth and along strike from the current resource. Thundelarra s objective is to define sufficient uranium resources within the project area to justify establishmentt of a central processing facility that can treat ore from several satellite deposits. The above information regarding the Thunderball deposit and Thundelarra s plans for exploration of the deposit have been taken from Thundelarra s public disclosure. Crocodile Gold has an agreement with Thundelarra in which Thundelarra has the right to explore for uranium on certain Crocodile Gold tenements while Crocodile Gold retains all other metal rights including TSX:CRK OTCQX:CROCF FRANKFURT: XGC www.crocgold.com
precious metals and base metals. Crocodile Gold has a 30% free carried interest until development in the uranium rights on the Exploration Lease where Thunderball is located while Thundelarra holds the remaining 70% interest. The location of the properties included in the joint venture and of the Thunderball deposit can be viewed in Figure 1 below.
