RIO ALTO ANNOUNCES SHAREHOLDER AND COURT APPROVAL OF THE PLAN OF ARRANGEMENT

Rio Alto Mining Ltd.'s previously announced plan of arrangement involving Rio Alto, Tahoe Resources Inc. and 1860927 Alberta Ltd. has been approved by the shareholders of Rio Alto and the Court of Queen's Bench of Alberta.

Rio Alto held a special meeting of shareholders earlier today, at which 99.81 per cent of the shares represented at the Rio Alto meeting voted in favour of the arrangement. On closing of the arrangement, all of the issued and outstanding common shares of Rio Alto will be exchanged on the basis of 0.227 of a Tahoe common share and 0.1 cent in cash per Rio Alto common share. Upon completion of the arrangement, existing Tahoe and Rio Alto shareholders will own approximately 65 per cent and 35 per cent of the combined company, respectively.

Rio Alto was also granted a final order approving the arrangement by the Court of Queen's Bench of Alberta today.

Assuming all other terms and conditions to the arrangement are met, it is expected that the arrangement will close on April 1, 2015.

We seek Safe Harbor.
