Tahoe’s Peruvian development consists of the La Arena II project adjacent to the La Arena Mine. Exploration activity during the third quarter of 2018 concentrated on drilling outlying targets north and south of the Shahuindo mine. In addition, early-staged exploration advanced on regional targets surrounding both the La Arena and Shahuindo resource areas.

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.

Gold River

The Gold River gold deposit is located along the Gold River Trend, which is 4 kilometers south of the Timmins West Mine. At this time, there are no Measured Mineral Resources nor Mineral Reserves reported for the Gold River deposit. Exploration at the Gold River Trend in 2017 included drilling of approximately 19,000 meters to refine the geologic model interpretation, evaluate several extensional targets and provide metallurgical samples. Additional infill/metallurgical and extensional drilling is planned for 2018.

Juby

The Juby gold property is a large near-surface deposit located along the Ridout-Tyrrel Deformation Zone in Northern Ontario. At this time, there are no Measured Mineral Resources nor Mineral Reserves reported for the Juby deposit. Evaluation of the Juby deposit in 2017 included review of the current resource model as well as a reconnaissance mapping and sampling program to evaluate potential new exploration targets on the property. Work in Q3 2018 continued to focus on refinement of the geological model, gold mineralogical and characterization studies, examination of new exploration targets, and planning and initiation of a new surface drill program which began in May.

Fenn-Gib

The Fenn-Gib gold deposit is an advanced stage exploration project situated in the southern portion of the Abitibi Subprovince. At this time, there are no Measured Mineral Resources nor Mineral Reserves reported for the Fenn-Gib property. Exploration at the Fenn-Gib deposit in 2017 included approximately 38,000 meters of infill and extensional drilling. Work is currently underway to update the geologic and resource models as well as to finalize results from a first phase of metallurgical test work.
