La Arena II
La Arena II is a large-tonnage copper-gold porphyry deposit located in close proximity to the currently producing oxide gold deposit at the La Arena mine in Peru. Copper and gold mineralization is hosted in a multi-stage dacitic to andesitic porphyry intrusion; the vast majority of porphyry-hosted mineralization is sulfide.
The Company released a Preliminary Economic Assessment of the La Arena II project in the technical report dated February 20, 2018 which envisions average annual production of 207 million pounds of copper and 149 thousand ounces of gold over a 21 year mine life. Tahoe expects to continue its evaluation of the La Arena II project with the intent of advancing the project to the prefeasibility or feasibility stage at the appropriate time. The timeline and estimated capital required to progress the project to the next stage are under review and no decisions have been made at this time.
