VANCOUVER, B.C. (November 29, 2010) – Tahoe Resources Inc. (TSX: THO) is pleased to announce the completion of an updated National Instrument (NI)43-101 compliant resource estimate and an independent Preliminary Assessment (PA) for its 100% owned Escobal Project in southeastern Guatemala. The PA defines a 3,500 tonne per day underground mining operation which would produce metals concentrates with very high silver content.

Highlights (all figures in U.S. Dollars)

  • Significantly enhanced resource confidence: Indicated silver resourcehas beenexpanded by 144% to245.2 million ounces at 500 g/t average grade.Inferred silver resource amounts to71.7 million ounces at 271 g/t average grade.
  • Feasibility-level metallurgical testing has confirmed recoveries averaging87% for silver and 75% for gold in metal concentrates.
  • Mine life is18 years at a planned production rate of 3,500 tonnesper day, with direct employment of approximately 500 employees in Guatemala.
  • Years one through five production averagesover 19 million silver ounces per yearat a total cash cost ofless than $3.00 perounce silver(net of by-product credits)which would makeEscobal one of the largest and lowest cost silver mines in the world.
  • After-tax net present value at a 5% discount (NPV5) amounts to $ 1.729 billion.
  • After-tax internal rate of return (IRR) is¬51% on an initial capital cost of $326.6 million with a payback of 1.5 years.
  • Over 90% of the project surface rights have been acquired, with the remainder under negotiation or under contract.
  • Significant upside remains in the Escobal vein trend and in other regional opportunities.

“We are extremely pleased with the Preliminary Assessment which projectsEscobalto beone of the world’s premier silver mines in terms of size, cost and economics,” said Kevin McArthur, President and Chief Executive Officer of Tahoe Resources. “The project design incorporates features which will provide the highest levels of environmental protection, workforce safety and operating efficiency, while minimizing community impacts. It is our intent to responsibly build this mine for the benefit of all stakeholders – governments, employees, communities and shareholders. We are now very focused on completing the remaining permitting and feasibility efforts leading to a construction decision in early 2012.”

Updated Mineral Resource Estimate1
The Escobalvein has been drilled along a strike length of approximately 1,700 metresand a vertical extent of 800 metres. The resourceestimate was updated by Mine Development Associates (MDA) incorporating data from nearly 12,000 samples from 220 diamond drill holes totaling 61,469metres.

The mineral resource estimate for the Escobal deposit contains 245.2 million ounces of silver classified as Indicated resources and 71.7 million ounces of silver classified as Inferred resources, with significant amounts of gold, lead, and zinc reported in both resource categories. A summary of the Indicated and Inferred resources, using a cut-off grade of 150 grams per tonne silver equivalent, is provided in the following table (grades refer to average grades):

MDA modeled and estimated the Escobal deposit resources by refining the geologic model, evaluating the drill data statistically, interpreting mineral domains on cross sections and level plans, analyzing the modeled mineralization statistically to establish estimation parameters, and estimating silver, lead, gold, and zinc grades into a three-dimensional block model using inverse distance cubed (ID3).

Silver-equivalent Indicated resources total 300.3 MM ounces at an average grade of 612 g/t and silver-equivalent Inferred resources total 95.2 MM ounces at an average grade of 359 g/t.

Preliminary Assessment

The PA calculates aBase Case after-tax NPV5 of $ 1.729 billion, with an after-tax IRR of 51%. The initial capital cost of the project is estimated to be $326.6 million with sustaining capital costs over the remaining mine-life estimated at $ 102.2 million. The payback period for the Base Case is estimated at 1.5 years after reaching commercial production. Economic sensitivities at different metals prices and discount rates were calculated as follows:

Mr. McArthur added, “One feature of the world’s best mines is the ability to repay capital investment in a short period of time. At today’s spot metals prices, expected Escobal payback occurs approximately one year after the start of commercial production – and the low total cash costs should allow the mine to remain profitable through any conceivable market price fluctuations. Furthermore, Escobal is a new discovery with very little regional exploration to-date. We expect to see resource growth over time and have incorporated future expansion possibilities into the design concept.”

Mining and Processing
The PA is based on an underground mine operation, mine backfill plant, tailings filtration, processing and concentrate production facility and the infrastructure capable of operating at 3,500 tonnesper day.

Extraction of the mineral resources will utilizelongholestoping methods, with paste backfill used to fill open voids. The mine will be developed via two primary development declines for the transportation of personnel, equipment, and materials, as well as transport of the mined resources to the surface for processing. Additional primary development will include two ventilation shafts and drifts connecting the primary declines. A total of 13,000 meters of primary and secondary underground development is contemplated during the 18-year mine life. The primary declines will also serve as platforms for exploration and definition drilling during the feasibility phase of the project.

Mineral processing will use differential flotation to produce lead and zinc concentrates for sale to a third-party smelter. Feasibility-level test work completed to date on the sulfide resources demonstrates recoveries of 87% for silver, 75% for gold, 83% for lead, and 83% for zinc, with the majority of precious metals reporting to the lead concentrate. Based on current test results, the lead concentratesare expected to contain very high levels of silver, between 15,000 and 30,000 grams per concentrate tonne, with very little in the way of penalty elements. Concentrates will be bagged and delivered to port in sea containers.

Over the mine life, mine production is expected to total 22.6 million tonnesat average diluted grades of 415 g/t silver, 0.47 g/t gold, 0.71% lead, and 1.22% zinc. Average total cash cost is expected to be $3.05 per silver ounce over the 18-year mine life, net of gold and base metal by-product credits.

Capital Costs
Capital costs for the Escobal Project include all project costs commencing January 1, 2010. The project capital costs were prepared by M3 Engineering and Technology Corporation of Tucson, Arizona. Initial capital costs are summarized as follows:

Sustaining capital costs over the remainder of the mine-life amount to $102.2 million primarily attributed to underground development and equipment replacement costs.

Operating Costs
M3 Engineering also prepared the operating cost estimates, working closely with Tahoe management personnel. Base Case unit costs are as follows:

Project Timeline
The Escobal project feasibility study is underway and is expected to be completed in 2011. Baseline studies and environmental documentation has been ongoing for nearly two years. Permitting for full mine operations is scheduled concurrent with the feasibility study and it is expected that the mine can be fully financed and ready for a construction decision by May 2012.

Underground exploration declines in the East and Central Zones are planned to commence in 2011. An application to amend the current exploration permit is on file with regulatory agencies and permits are expected early in 2011. The exploration declines will allow for efficient in-fill drilling and for deep drilling in the deposit with minimal surface disturbance.

Construction is expected to commence in May 2012, subject to project financing and acquisition of all necessary permits. Production is projected for late 2013 with commercial production being reached in early 2014.

Exploration Program
In 2009 and the first half of 2010, exploration programs at Escobal were designed to improve confidence in the established Inferred resource. This program succeeded in expanding the 2010 Indicated resource by 144% to 245.2 million silver ounces.

Ongoing exploration is designed to meet four objectives: further defining Escobal vein extensions through surface drilling;commencement of theunderground exploration decline in early 2011 to provide drilling platforms for in-fill drilling and deep extensional drilling; upgrading twelve other veins in the district to drill-ready status; and exploring new targets through the regional exploration program. The exploration budget for 2011 amounts to $3.5 million, excluding the underground decline project.

Exploration drilling continues to expand the known limits of the Escobal vein down-dip and laterally under post-mineral cover. Drilling in these areas is testing targets indicated byrecently completedstructural analysis and clay-alteration interpretations of the Escobalvein and surrounding satellite veins. Three diamond drills are currently testing these project targets.
Drilling in 2011 is designed to delineate new ore shoots within the Escobal structure through wider and deeper extensional step-outs. This program will be carried out principally from surface collars with underground drilling planned later in the year when drill stations are in place along the planned exploration decline.

As Escobal transitions into project development in 2011, a portion of our exploration effort will move to a regional focus. Using the geologic model developed at Escobal, prospective areas will be evaluated throughout the region while a more concentrated effort will be made to upgrade and drill viable targets that lie within Tahoe’s currently held concession areas. Twelve veins in addition to the Escobal vein have been discovered on the Company’s concessions. During 2010, clay alteration studies were completed over most of these occurrences and interpretation is underway for determining drill targets for 2011.
