VANCOUVER, Aug. 13 /PRNewswire-FirstCall/ - PETRO HORIZON ENERGY CORP. announces that it has received TSX approval to change its name to GREEN LIGHT RESOURCES INC. (TSXV.GR)

The Company believes that its new name, Green Light Resources Inc., better reflects its current vision and strategy: beginning with the acquisition of its Brazil Lake Lithium property in Nova Scotia. The Company will begin trading under its new name effective at the open on August 13, 2010 on the TSX Venture Exchange ("TSX-V"), under the new stock symbol, "GR".

About Green Light Resources Inc.:

Green Light 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 which 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.

As per a news release dated July 21, 2010, field crews have initiated the 2010 work program consisting of a detailed prospecting and mapping grid over the property. The focus will be on locating other pegmatite dikes in addition to the established North and South dikes. A baseline (North-South) would be established to cover the ground between Bloomfield and Deerfield and cross lines (East-West) put in at 100 meter intervals extending between the Brazil Lake road on the west and the Meguma/White Rock contact on the East. This would result in a 8 km long baseline and 2 km long cross lines. Detail work would be done on 25 or 50 meter lines where targets develop. All significant points will be surveyed in using GPS and mapping of all outcrops will be undertaken. Any areas that show signs of a potential pegmatite discovery would then be trenched or recommended for follow up exploration using secondary methods such as geochem and/or geophysics. Results may serve to define other drill targets for the drill program scheduled to proceed immediately thereafter.
