The Drills are now turning at Brazil Lake

(PRZCF.OTCBB) (PH0.FRANKFURT) (TSXV.GR)

VANCOUVER, Aug. 18 /PRNewswire/ - GREENLIGHT RESOURCES INC. (TSXV.GR), announces that it has signed a drilling agreement with Maritime Diamond Drilling Ltd., of Brookfield, Nova Scotia, to conduct a diamond drill program on its Brazil Lake Lithium and Rare Metal property in Nova Scotia. The program has commenced.

The drilling will be carried out on the two previously identified pegmatite dikes with the bulk of the drilling targeting the North dike. Approximately 1620 m in 10 holes will be drilled to define the North dike down to the -125 meter level over a strike length of 150 meters. Three tiers of holes will be drilled at 75 meters, 100 meters, and 125 meters. These holes will assist to define the geometry and grade of the North pegmatite dike. The second target is the South dike which will receive approximately 560 meters in 5 holes to define the dike down to the 50 meter level. If these holes are successful, the Company intends to drill another tier of holes at the 75 meter level which would entail a further 700 meters of drilling.

The current budget is for approximately 2,500 meters of drilling which allows for some exploratory holes outside of the main two target areas. Until very recently, the Company has had field crews conducting a detailed prospecting and mapping program over the property surrounding the current know dikes. The focus is on locating other pegmatite dikes in addition to the established North and South dikes. Excess drilling footage will be used to drill these new targets should any be found.

On June 17, 2010, the Company filed a NI 43-101 compliant report on the Brazil Lake property. Approximately 30 holes were drilled by the property's previous private owners. Results indicated that cores returned Li2O grades of economic interest. More specifically, hole BZ-02-15 returned a weighted average Li2O grade of 1.47% over a true width of 12.53 meters, beginning at a down hole depth of 30.9 m, and BZ-93-4 returned a weighted average grade of 1.27% Li2O over 20.9 meters true width, beginning at a down hole depth of 47.1 meters. These intercepts and others contain sub-interval Li2O grades exceeding 2.5%.

Other Potential Rare Metals and Industrial Minerals

Prior work on the Brazil Lake pegmatites has also been directed toward definition of valuable mineral or metal components additional to lithium, and preliminary results show that potential exists for creation of industrial mineral products such feldspar, quartz and mica. The company is also investigating potential for recovery of rubidium, tantalum and tin from the pegmatites. On March 2nd, the Company announced assay results from drill holes which addressed other rare metals contained within the Brazil Lake pegmatites. These included rubidium ("Rb"), beryllium ("Be") and tantalum ("Ta"). Examples of the grades included Hole #02-15 in the lithium pegmatites which returned values up to 1,398 parts per million ("ppm") Rb over 15.3 meters including 2,625 ppm Rb over 4.2 meters. Hole #02-24 in the lithium pegmatites returned Be values of up to 200 ppm over 35.8 meters, including 304 ppm Be over 14.9 meters. Also, hole #93-2 in the lithium pegmatites returned Ta values of up to 102 ppm over 24 meters, including 541 ppm Ta over 1.0 meter.

About Greenlight Resources Inc.:

Greenlight Resources Inc. is a Canadian exploration company focused on the discovery and development of Lithium and rare metal deposits. The Company is currently focused on the 3,160 acre Brazil Lake property is located approximately 30 kilometres north of Yarmouth, Nova Scotia, and 12 kilometres west of the Avalon Rare Metals (AVL) East Kemptville Project. Drilling to date has successfully revealed two Lithium bearing pegmatite dikes. In addition to Lithium, the dikes host several other rare metals such as tantalum, niobium, beryllium, tungsten tin and rubidium. Metallurgical bench testing to date has also revealed other potential economic targets, including cosmetic grade mica, silica chloride, aluminum chloride and rubidium enriched potassium feldspar.
