Subsequent to the end of Q2, Rio Alto has closed its acquisition of Sulliden Gold Corporation Ltd. and has commenced re-engineering studies to determine the capital cost and timing of the starter gold project the Company intends to build at Shahuindo during 2015.

The Company also anticipates completing the current oxide drilling program at La Arena by mid-September and the feasibility study for the Phase II Copper/Gold Sulphide Project by year end in preparation for a new mineralized resource and reserve statement for La Arena to be released in January 2015.
