TORONTO, ONTARIO--(Marketwire - March 12, 2012) - Crocodile Gold Corp. (TSX:CRK)(OTCQX:CROCF)(FRANKFURT:XGC) ("Crocodile Gold" or the "Company") is pleased to provide the following assay results from its Iron Blow base metal/precious metal project in Northern Australia. Highlights include:
Crocodile Gold's objective with the 2011 drilling was to gain a better understanding of the deposit's mineralization and expanding mineral resources. The Company will be recalculating resources for the Iron Blow deposit once it has finalized its interpretation of the mineralized zones. Table 1 summarizes assays of significance.
Recently completed drilling indicates that there is both a base metal and a precious metal system associated with massive sulphides and a peripheral gold enriched system that is associated with only very minor sulphides.
Mark Edwards, the Company's Manager of Geology and Exploration, commented "Crocodile Gold's massive sulphide deposits represent an intriguing target for the Company because of their enrichment in gold and silver. The recently completed airborne VTEM survey is the ideal tool to locate additional concentrations of massive sulphides and subsequent exploration work can soon focus in on prioritized targets. The Iron Blow massive sulphides display a strong airborne EM response with a coincident magnetic anomaly caused by concentrations of pyrrhotite."
The Iron Blow deposit has been known since 1873 and its oxide cap has been mined in the past for its precious metal content. Records indicate that 10,000t of oxide material grading 9.0g/t Au and 250g/t Ag as well as 25,000t of sulphide material grading 7.0g/t Au and 360g/t Ag were mined in the 1980s.
Recent drilling by past operators produced an inferred NI 43-101 compliant resource of 3.17 million tonnes grading 2.08g/t Au, 100.9g/t Ag, 0.19% Cu, 0.76% Pb and 3.28% Zn. The deposit was interpreted to consist of 6 separate lenses, which were open along strike and to depth.
In 2011, the Company also drilled its Mt. Bonnie project, another known massive sulphide deposit on the same stratigraphic horizon as the Iron Blow deposit. Assays are pending. A mineral resource statement is planned for the Mt. Bonnie deposit, which has seen past production from underground workings and a small open pit of past production in the 1980s amounting to 110,000 tonnes grading 7 g/t Au and 230 g/t Ag. A historic resource* consisting of 650,000 tonnes grading 1.7 g/t Au, 279 g/t Ag, 0.5% Cu, 2.0% Pb and 9.0% zinc has been reported.
Once all data has been compiled and interpretations completed Crocodile Gold will assess its base metal and precious metal deposits to determine their potential economic viability. The geology of the region is favourable for hosting massive sulphide deposits and a concerted exploration effort could greatly increase the resources available to the Company. Crocodile Gold will then determine its options with respect to this style of mineralization and its strategic importance to the Company's future mine plans.
*Historical estimates derived from the report prepared for Northern Gold, entitled "Mt Bonnie and Iron Blow Projects, January 2005 prepared by Northern Gold NL, January 2005. This report was not prepared in accordance with currently accepted guidelines for the preparation of Mineral Resources and Mineral Reserves, and does not comply with National Instrument 43-101 ("NI 43-101") and are not considered by Crocodile Gold, as current mineral resources or mineral reserves. These resource estimates may have also been depleted by past mining, and although possibly demonstrative of the potential grade of the deposits, the historical estimates of tonnage and grade are not considered indicative of the remnant potential resource. A qualified person, as such term is defined under NI 43-101, has not done sufficient work to classify the historical estimate as current mineral resources or mineral reserves. Crocodile Gold is not treating the historical estimate as current mineral resources or mineral reserves and the historical estimate should not be relied upon.
Note: Gold equivalent grade is calculated by dividing the silver assay result by 55 and assuming 100% metallurgical recovery

Qualified Person
Mark Edwards, Geology Manager of Crocodile Gold Australia Operations is a "qualified person" as such term is defined in National Instrument 43-101 and has reviewed and approved the technical information and data included in this press release.
Quality Assurance and Quality Control:
1. Drill samples were assayed at NTEL in Darwin
2. Gold Assay results are based on 50g fire assays, base metal analysis are from ICPMS (Inductively Coupled Plasma Mass Spectrometry)
3. All intersections from diamond samples are either NQ or HQ half-core.
4. Diamond sample intervals are determined using lithological controls or 1.0m whichever is larger
5. Mean gold grades have been calculated on a minimum of 1.0m interval, 0.5 g/t lower cut-off and maximum 3m internal dilution. No upper cut has been applied
6. All intersections are down-hole intervals.
7. All deviations have been verified by down hold camera.
8. QAQC for these holes has been checked and verified through blind standards, field duplicates, lab repeats and barren flushes. QAQC results are within expected limits.
About Crocodile Gold
Crocodile Gold is a Canadian company with operating gold mines in the Northern Territory of Australia with a land package of over 3,300 km2. Crocodile Gold is currently mining a number of open pits in the Howley Corridor. The Company is also developing the Cosmo underground mine. Ore is processed at the Union Reefs Mill with a capacity of 2.4 million tonne per year. Crocodile Gold has 3.175 million ounces of NI 43-101 compliant Measured and Indicated mineral resources and 2.14 million ounces of Inferred mineral resources (see the NI 43-101 compliant technical report entitled "Report on the Mineral Resources and Mineral Reserves of the northern Territory Gold and Base Metals Properties for Crocodile Gold Corp." by Fleur Muller, Mark Edwards and Heath Gerritsen dated April 4, 2011, filed under the Company's profile on SEDAR for the details regarding these mineral resource estimates). The Company has an extensive exploration program in place and is drilling on several key properties on its expansive land package. Crocodile Gold's main focus is on the Cosmo Mine, the Union Reefs and Maud Creek project areas.
