VANCOUVER, July 21 /PRNewswire-FirstCall/ - PETRO HORIZON ENERGY CORP. (TSXV.PHE), is pleased to announce that the joint management committee with the operator Champlain Mineral Ventures Ltd, has now authorized the mobilization of the field crews, to begin conducting the 2010 work program.

Before drilling begins, a detailed prospecting and mapping grid over 3,160 acres at Brazil Lake will be conducted. This will cover the entirety of the original exploration licences only, not the newly staked claims. 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 there after.

On Behalf of the board of directors,

"Ron Bourgeois"

Ron Bourgeois, President
