Vancouver, British Columbia, Canada, April 13, 2011 – Rock Tech Lithium Inc. (TSX-Venture: RCK; Frankfurt: RJIA; Pink Sheets: RCKTF) (the “Company” or “Rock Tech”) is pleased to announce additional results from its 2010/2011 exploration program at its Georgia Lake lithium project in Northwest Ontario. The assay results include 1.17% lithium oxide (Li2O) over 16.0 metres in drill hole NC11-04, 1.32% Li2O over 9.0 metres in drill hole NC11-01, 1.43% Li2O over 7.0 metres in drill hole NC11-05 and 1.19% Li2O over 8.2 metres in drill hole HW11-02. Other lithium oxide and rare metals intersections of interest were also encountered.

The Company further reports that it has completed the field work related to Phase 1 of its exploration program at Georgia Lake. In addition to drilling three holes related to the bulk sampling for metallurgical testing, this phase was comprised of 7,682 metres of diamond core drilling over 47 NQ-size core drill holes. A total of 1,426 core samples, including 206 Quality Control samples, have been shipped to SGS Laboratories in Toronto for chemical assaying. The results of this drill program will be the basis for bringing the historical resource at the Nama Creek and Conway leases and claims to an independent NI 43-101-compliant inferred resource by the end of June 2011.

The metallurgical testing will provide insight into recovery rates utilizing floatation and heavy media separation methodologies as well as processing battery-grade lithium carbonate. These results are significant drivers for the Company’s downstream business strategies. Rock Tech expects the results of the independent metallurgical tests by the end of May 2011.
