MAY 24, 2011 – LAVAL, QUEBEC – Critical Elements Corporation (TSX.V: CRE) (US OTCQX: CRECF) (FSE: F12) is pleased to announce the latest results of drilling on the Rose Lithium-Tantalum deposit. The table below shows the results for holes LR-11-156 to LR-11-171 (except for Hole LR-11-167), drilled to test the eastern extension of the zones. All the holes intercepted the mineralized zones with similar grades to earlier results. Furthermore, some intersections returned particularly high Tantalum grades, such as holes LR-11-160, LR-11-164, LR-11-166 and LR-11-169, which yielded 405, 483, 483 and 466 PPM Ta2O5 respectively. Furthermore, the results of six other holes drilled on the JR showing confirm the potential for resource delineation at that showing. With the exception of Hole JR-11-16, for which results are still pending, all these holes returned significant lithium and Tantalum values.

A map showing the location of the holes drilled on the Rose Lithium-Tantalum project can be found in the Projects section of Critical Elements’ Website.
The recently obtained results are as follow:

* 1 ppm = 1 g/t
All samples were sent for analysis in sealed containers to the ALS Chemex laboratory in Val-d’Or by employees of the Company. ALS Chemex is the laboratory used for analysis of all samples from programs on the Lac Pivert/Rose property. The samples are weighed and identified prior to sample preparation. The samples are crushed to 70% minus 2 mm, then separated and pulverized to 85% passing 75 ?M. All samples are analyzed using ICP-MS, with full analysis for 47 elements.
About Critical Elements Corporation
Critical Elements is actively developing its 100%-owned Rose Lithium-Tantalum flagship project located in Quebec. The project hosts a current Indicated resource of 11.4 million tonnes of 1.34% LI2O and 165 ppm Ta2O5 and Inferred resource of 2.1 million tonnes of 1.27% LI2O and 138 ppm Ta2O5.

Critical Elements has commissioned a prefeasibility study for the project from Genivar, one of the largest independent engineering firms in Canada. Genivar is also doing an environmental study, and Acme Metallurgical Ltd. of Vancouver is carrying out project metallurgy.

Critical Elements’ portfolio also includes rare-earth and Tantalum-Niobium projects in the Rocky Mountains of British Columbia and in Quebec, as well as a 50% interest in the Croinor project, which is located in Quebec and contains a measured and indicated resource of 814,228 tonnes at 9.11 g/t Au, for 238,414 ounces of gold at a 5 g/t cut-off.
