Canmex to Commence Trading as Africa Oil Corp. Effective August 20, 2007

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Aug. 17, 2007) - Canmex Minerals Corporation ("Canmex" or "the Company") (TSX VENTURE:CXM) is pleased to announce that effective at the market opening on August 20, 2007, the Company will commence trading under its new name, Africa Oil Corp. The new trading symbol of the Company will be "AOI". The new CUSIP number will be Q08 29Q 101. The name change is to better reflect the focus and direction of the Company.

The Company holds an 80% interest in two licenses encompassing the highly prospective Dharoor and Nogal Valleys in the state of Puntland in northern Somalia. Both blocks are considered world-class exploration plays with petroleum systems geologically similar to and formerly contiguous with those in the prolific oil producing Republic of Yemen.

A comprehensive exploration work program is underway on the Nogal and Dharoor Valley Blocks, including geological fieldwork, reprocessing of prior 2D seismic and review and integration of all geophysical and geological data. A drilling rig will be mobilized to the area late in 2007 with the anticipation of spudding the first well in early 2008.
