TAHOE ANNOUNCES RESULTS OF LA ARENA II PRELIMINARY ECONOMIC ASSESSMENT

Tahoe Resources Inc. has released the results of its preliminary economic assessment for La Arena II, a copper-gold porphyry project in Peru. Tahoe expects to continue its evaluation of La Arena II with the intent of advancing it to the prefeasibility or feasibility stage. The timeline and estimated capital required to advance the project to the next stage are under review. The project will be evaluated in the context of existing operations and pipeline opportunities with the intention of progressing it responsibly in order to maximize value for Tahoe's shareholders.

La Arena II PEA Highlights:

• Total Measured and Indicated Mineral Resources of 5.6 million ounces of gold and 5.8 billion pounds of copper and Inferred Mineral Resources total 683 thousand ounces of gold and 349 million pounds of copper
• 21 year mine life
• Average annual production of 149 thousand ounces of gold and 207 million pounds of copper, plus an additional 226 thousand ounces of gold and 115 million pounds of copper recovered over a two year pre-production period
• Total gold and copper recovered in dore and concentrate over the mine life is estimated to be 3.4 million ounces of gold and 4.5 billion pounds of copper
• Open pit mining rate of 80,000 tonnes of mill feed per day, with flotation processing to create a high-quality copper+gold concentrate, with run-of-mine heap leaching of oxide gold cap
• Capital costs estimated at $1.36 billion for initial project capital (net of pre-production operating credit) and $1.09 billion for sustaining capital over the mine life
• Average annual after-tax cash flow of $273 million
• Average co-product cost of $600 per ounce gold and $1.55 per pound copper (1) . Average annual cash operating costs are $395 million. Total operating cost is $12.87 per tonne processed
• The base case economic estimate is an after tax net present value of $824 million, using a 8% discount rate, and an after-tax internal rate of return of 14.7% with a payback period of 4.6 years at metal prices of $3.30/lb copper and $1,300/oz gold
• Drilling at depth demonstrates the continuation of mineralization below the bottom of the resource pit shell at similar grades
• Existing infrastructure synergies between at La Arena and La Arena II include skilled workforce, power line, and roads

Mineral Resources as of January 1, 2018 for the La Arena II project are summarized as follows:

(1) Totals may not sum due to rounding  
(2) Mineral Resources are reported within a $4.00/lb copper and $1,500/oz gold pit shell using cut-off grades of
    0.10 g/t gold for oxide Mineral Resources and 0.18% copper-equivalent for sulfide Mineral Resources.

The 2018 La Arena II PEA supersedes the 2015 feasibility study. The prior feasibility study considered a small capital-constrained project with restrictive financial hurdles. The resulting Mineral Reserve estimate presented in the prior study represented only a small portion of the total Mineral Resources. Tahoe's PEA includes new exploration drilling results and re-evaluates the La Arena copper-gold porphyry project in the context of a long-term copper-gold project designed to world standards.

The prior study included Probable Mineral Reserves of 63.1 million tonnes at average grades of 0.43% copper and 0.31 g/t gold containing 579 million pounds of copper and 633 thousand ounces of gold. There are no Mineral Reserves reported in the 2018 PEA as the scope of the project has changed significantly with new exploration results, a refined geologic model, an updated Mineral Resource estimate, increased mining and processing rates, modified processing scheme, and the use of alternative tailings disposal facilities. While a portion of the data generated for the 2015 feasibility study provided support for some of the assumptions incorporated into the 2018 PEA, much of the mining, processing, geotechnical, hydrological, social, and capital and operating cost parameters used in the 2015 study are no longer applicable to the project as envisioned in the 2018 PEA.

For more information, please refer to the new NI 43-101 technical report for the La Arena property, Technical Report on the La Arena Project, Peru , which includes an update of the existing La Arena Mine oxide gold heap leach operation and a PEA of the La Arena II copper-gold porphyry project. The technical report is available on the Company's website and on SEDAR and Edgar.

NI 43-101 required disclosure: Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. The La Arena II PEA is preliminary in nature and includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized.
