("Platte River") by way of a statutory plan of arrangement (the "Acquisition"). The Acquisition was previously announced in the Company's news releases dated October 15, 2009 and January 13, 2010.

Pursuant to the terms of the Acquisition, all of the outstanding common shares of Platte River ("Platte River Shares") have been acquired in exchange for 74,832,020 common shares of the Company ("Scorpio Shares"), representing an exchange ratio of approximately 3.53 Scorpio Shares for each Platte River Share.

In addition, a further 4,414,972 Scorpio Shares are now issuable to the holders of Platte River's stock options and common share purchase warrants, which, by their terms, became exercisable for Scorpio Shares upon the closing of the Acquisition.

Peter Hawley, Chairman and Chief Executive Officer of Scorpio, stated: "We are very pleased to have completed the Platte River acquisition, which allows us to move forward with the systematic planning of our mill facility expansion and the development of the San Rafael Upper and Main zones open pit extraction. Details of the planned expansion program, including metallurgical work, expected metal production for 2010 and a forward estimate of metal production for 2011, will be released in the weeks ahead. With this acquisition, the Company now controls the entire Cosala mining camp. The high quality, advanced-stage deposits acquired will enable a continuous flow of production growth, while at the same time, allow us to bring along secondary deposits to the development stage for future mine planning."
