Rock Tech Increases Land Position to 11,481 Hectares on its Georgia Lake Lithium Project

Vancouver, British Columbia, April 15, 2010 — The Board of Directors of Rock Tech Resources Inc. („Rock Tech“ or the „Company“) is pleased to announce that the Company has been granted 41 claims covering 6,816 hectares (16,842 acres) in 426 claim units at its Georgia Lake lithium project located in the Thunder Bay Mining District in northwest Ontario.

With the acquisition of these claims, Rock Tech holds 100% interest in a total of 11,481 hectares (28,370 acres) in the Georgia Lake properties. These new claims, which encompass numerous historically mapped spodumene bearing pegmatite dykes, provide additional prospective ground around the existing claim blocks. Additionally, the newly acquired claims has allowed the Company to consolidate its existing eight claim blocks into three larger contiguous blocks and provides the Company with the potential to expand its historical resource of 9 million tons with grades of 1.14% Li2O¹. The claims recently granted by the Ontario Ministry of Mines, cover the following historically reported / mapped pegmatite dykes (reference: E. G. Pye 1965): Dunning Lithium Dykes

– Several lithium dykes located about 3,000 feet (914 metres) south of the east end of Palace Lake.

Power Line Lithium Dyke

– Is reportedly located along the Hydro Ontario transmission line and was investigated by Noranda Exploration Company Limited in 1955. A total of seven claims were granted to the Company covering the Dunning and Power Line dykes which are located to the south of Rock Tech’s Conway Claim Block. During the 2009 winter exploration drill program, Rock Tech drilled 1.62% Li2O over 10.5 metres and 1.54% Li2O over 8.9 metres in two separate drill holes on the Conway Claim Block2.

Kenogamisis Lithium Dyke

– This pegmatite is a tabular shaped body, striking N60°E and dipping 70°NW, and has been traced intermittently for about 650 feet from the Shore of Downey Lake. Three narrow pegmatite dykes, spaced at intervals of 10 and 40 feet were also mapped on the east shore of Downey Lake. A total of six claims covering these dykes which are located adjacent to the west of the Nama Creek Claim Block have been granted. Surface samples from the Nama Creek Claim Block from the Company’s 2009 ground program indicated 2.16% Li2O3, and 1.10% Li2O with anomalous grades for rare metals4.

Foster-Lew Pegmatite Extension

– A total of eleven claims were granted covering the westward extension of the Foster-Lew pegmatite dyke. The Foster lithium bearing pegmatite dyke strikes N80° to 85°E and dips 80° to 85°S, and is exposed for a distance of some 75 metres with a width of some 9 metres. The Lew pegmatite dyke is located some 450 metres southwest of the Foster dyke, striking northeast and dipping steeply south. It was traced for a distance of some 30 metres, having a width of 2 to 3 metres. Surface samples from the Foster Lew Claim Block from the Company’s 2009 ground program indicated 2.26% Li2O and anomalous values of rare metals4.

McVittie Pegmatite Extension

– Two claims were granted covering the western extension of this dyke which strikes N25oW to N10oW and dips 80oE to vertical. During the years 1955 to 1956, Noranda Mines Ltd. completed extensive exploration program consisting of prospecting, trenching, geological mapping and diamond drilling. Surface samples from the McVittie Claim Block from the Company’s 2009 ground program indicated 1.63% Li2O and anomalous values of rare metals4.

Numerous Southern Pegmatites:

– Fifteen claims were granted covering numerous pegmatite dykes marked on Geological Map No. 2056, Georgia Lake Area. These dykes are marked in the area between the Company’s Aumacho River Claim Block and MNW Claim Block. The Aumacho River Pegmatite contains at least three lithium bearing dykes – Brink (or No. 1), the No. 2, and the No. 5. A mill test carried out by the Department of Mines and Technical Surveys (Ottawa, Ontario) indicated that heavy media separation would yield 6.27% lithium with a recovery of about 90%, with a second test indicating that floatation would yield a concentrate containing 5.93% lithium at 90% recovery as well. The MNW pegmatite dyke occurs in massive, medium-grained, pink granite and is localized along a fracture, which strikes north and dips 75o; to 80oW. It ranges up to 13.5 metres in thickness and has been traced in outcrops and trenches intermittently for a distance of about 425 metres. The main dyke on the MNW Claim Block was sampled by an
 operator and was found to average better than 1.5% Li2O. 2009 surface samples assay results from these blocks indicated up to 7.22% Li2O and significant anomalous values of rare metals, including up to 3.54% beryllium and 0.39% cesium4.

1The historical resource estimates reported in this press release are taken from Ontario Department of Mines Geological Report No. 31 titled, „Geology and Lithium Deposits of Georgia Lake Area“, by E.G. Pye, 1965. The author of the report took resource estimates from the assessment reports filed by previous operators, and other available sources. The company believes that the estimate is relevant to an appraisal of the merits of the property because it was based on drilling, trenching and other exploration work in each claim block on the property, and because there is no evidence of any subsequent resource estimation work on the property. No additional recent data on resource estimates are available in the public domain. No additional work has been completed by a qualified person to classify the historical resource estimate as a current resource or reserve. The company is not treating the historical resource as a current mineral resource or reserve. The historical resource es  timate should not be relied on and does comply with NI43-101 standards.
