On April 6, 2010 Argex announced that it is has engaged Process Research Ortech Inc. (PRO) to develop an effective and economically viable process for the recovery of titanium dioxide from its 100% owned La Blache deposit's ore.

PRO has extensive experience in titanium processing with several patents issued and pending. For its Canadian patent application on its proprietary mixed chloride technology to treat titanium containing ores to produce titanium dioxide, the patent allowance has been made. The process has been previously demonstrated for other titanium containing ores from Canada and overseas with an extraction efficiency in excess of 90% for both titanium and iron as well as production of over 99.8 % pure titanium dioxide.
