The hard work and focus of the Lima based management team and mine operations personnel to achieve this result allows Rio Alto to stand out from its peers as a solid, performance oriented, high margin mid-tier gold producer. The forecasted performance at La Arena and the development plans for Shahuindo during 2015 all bode well for the Company's future.
