TAHOE DRILLING FURTHER EXPANDS KNOWN ESCOBAL MINERALIZATION
EIS Approved in October – Development Remains On-Schedule
VANCOUVER, B.C. (November 14, 2011) – Tahoe Resources Inc. (Tahoe or the Company)(TSX: THO) is pleased to announce new drilling results from the Escobal project in southeast Guatemala. This update demonstrates significant expansion of known mineralized zones and provides continued optimism for deeper geologic upside at the project.
“These drill results are very encouraging,” said Brian Brodsky, Tahoe’s Exploration Vice President. “Drilling along vein extensions in virtually all directions demonstrates that the Escobal mineralized system is much more extensive than previously thought,” he added. “Escobal is already one of the largest and highest grade silver deposits under development. We expect these findings will enhance the mine plan, which currently calls for 317 million silver ounces to be mined over the next 18 years,” said Mr. Brodsky.
Since the latest announcement of exploration drill results on June 8, 2011, a total of 61 holes for 29,588 metres were drilled, bringing project-to-date drilling to 113,174 metres in 348 holes. Currently, eight drill rigs continue to in-fill the known resource and further define extensions to Escobal mineralization. The zone is now over 2,200 metres in strike length and 1,200 metres from the top elevation in the east to the bottom elevation in the west Margarito zone. The trend remains open laterally to the east and west, as well as to depth.
Exploration results point to significant resource growth potential in several areas:
- Wide-spaced East zone drilling has extended known mineralization to more than twice the area defined in the prior published resource study. A newly discovered change in deep vein inclination offers substantial future exploration upside in the down-dip area previously thought to be of limited potential. This new development is described as a dilational jog similar to what has been observed in the Central zone.
- West zone step-out drilling continues to define the west Escobal and Margarito veins more than 500 metres from the limit of prior resource drilling. Recent deep drilling confirms the down-dropped fault offset of the Margarito vein in the extreme west portion of the area.
- In-fill drilling in the deep Central zone continues to enhance confidence in those areas previously categorized as Inferred Resource. A number of deep Central zone intercepts remain open to depth and form compelling targets for future deep underground drilling.
Extensional and in-fill drilling at Escobal is expected to continue at the current pace utilizing eight drills until year-end. All drilling completed by year end is planned to be incorporated into a new NI 43-101 resource study and Preliminary Economic Assessment (PA), which is expected to be finalized in the second quarter of 2012. The goal of the new PA is to produce a mine plan in excess of 20 million ounces of annual silver production over the majority of the mine life.
The 2012 exploration budget of $10 million was approved by the Tahoe Board of Directors in the November 2011 budget meeting. This amount will support continued step-out and in-fill definition drilling at Escobal, as well as drilling at priority regional targets. The Escobal drillhole database is available on our website at www.tahoeresourcesinc.com. Available data include all new drill results, drill long sections, plan map of vein occurrences and recent site photographs. The long section is included at the end of this press release.
West Zone – Margarito Vein Definition
In-fill and step-out drilling continues to increase confidence in the Margarito vein mineralization, first reported in the June 8, 2011 press release. A total of 15 drillhole intercepts now define the Margarito vein over a +500 metre strike length and +600 metre vertical range, open to the west and to depth. The zone continues to express characteristics similar to the Escobal vein, with a transverse northwest strike, a steep south inclination and wider intercepts than those observed along the western Escobal vein. Several drillholes, such as E-297 and E-305, intersected both Escobal and Margarito veins, demonstrating the spatial separation of the individual structures.
The Margarito vein is entirely preserved with upper barren vein giving way to significant mineralization at depths of 200-250 metres below surface. To the west, the vein is down-faulted approximately 150 metres, evidenced by displacement of andesite and limestone markers and upper-level mineralization in holes E11-304 and E11-312. This western area is a high-priority prospect targeted for deep drilling in 2012.
With respect to the deep west limestone reported in our last press release, additional deep drilling has not delineated continuous carbonate basement rocks. Limestone detected in several holes is thought to comprise relatively thin (~80m) lenses or wedges within the volcaniclasticsediment basement unit. A deep carbonate hosted target is still anticipated, further deep drilling is planned for 2012, utilizing a specialized deep drill.
Table 1 – West Zone Highlights
Recent drilling in the deep Central zone was designed to add definition and convert a large portion of the PA resource from the inferred to the indicated category. Seven drillholes were completed since the last project update. Generally, in-fill holes appear to corroborate resource modeling. High-grade results (E-322) encountered in the deep portion of the zone extend mineralization 100 to 150 metres deeper than originally defined by earlier drilling. These deeper reaches of the zone remain open and will be further explored through underground drilling as the current West decline development progresses.
Table 2 – Central Zone Highlights
Eleven new holes have extended the East zone 300 metres east to a total 800 metre strike length and 300 metres down-dip to a total 500 metre vertical range. Additionally, subsequent drilling in the area directly below the initial resource area (E-311, E-315) has demonstrated that the typical south-dipping vein transitions to a dilational jog similar in character, rock type and elevation as found in the Central Escobal zone. Additional drilling is currently underway to further assess open vein continuity to the east, west and to depth.
Table 3 – East Zone Highlights
Given encouraging drillhole and assay results, exploration priority throughout 2011 to-date has been assigned to the Escobal vein area. Regional exploration drilling is now expected to commence during the fourth quarter of 2011, as Escobal construction and site development activities accelerate.
Regional work is scheduled to start at the Varejones project, located 25 kilometres east of Escobal. At Varejones, three separate sub-parallel veins of similar grade and character to Escobal have been identified along a 3,000 metre long trend. The Company received environmental permits for planned drilling, entered agreements with surface owners and made road improvements and site preparations at Varejones. A portable core drill has been scheduled for startup in December and initial drill results are expected early in 2012.
National Election Results
On November 6, Guatemala held its presidential run-off election in Guatemala. Otto Perez Molina of the conservative Partido Patriota was elected and will be inaugurated on January 14, 2012. Mr. Perez ran primarily on a platform of law and order, and is expected to be supportive of business and responsible natural resource development. Since the end of the Civil War in 1996, Guatemala has experienced peaceful, democratic transitions of power with the election of a new president every four years.
Escobal Development Update
On February 15, 2011, Tahoe received approval for enhanced exploration and development activities at Escobal, including development of two declines, completion of a new access road and power line into the property, and construction of temporary facilities to support underground exploration. On October 21, 2011, Tahoe received approval of its Environmental Impact Statement (EIS) approval, clearing the way to commence construction of the process plant and supporting facilities. Applications have been filed with the Ministry of Energy and Mines (MEM) for the Escobal exploitation license, which is required prior to production start-up.
In late October 2011, Tahoe’s EPCM contractor, M3 Engineering and Technology, began mobilizing contractors to commence earthwork and construction of the process plant and associated support facilities. Miner training is ongoing and advance in the declines is progressing. A total of $83.1 million has been committed to-date toward the construction of the project, including $27.8 million for mine development and production equipment and $37 million for major process plant equipment. Mining equipment began arriving in May and the first major process plant components are expected to arrive early in 2012. All long lead-time items have been ordered and the original capital cost estimate of $326.6 million remains unchanged. As of September 30, 2011, the Escobal project employed a total of 365 people, of whom 95% are Guatemalan.
Third Quarter Financials
As of the end of the third quarter of 2011, the Company had a total of $382.6 million in cash, cash equivalents and term deposits and no debt. The Company expects this working capital is sufficient to fully fund project construction. First silver production is anticipated in the second half of 2013, with commercial operations expected in the first quarter of 2014.

Quality Control and Assurance
Exploration drill samples were prepared by BSI Inspectorate Laboratories in Guatemala City and analyzed by BSI Inspectorate Laboratories in Reno, Nevada. A Quality Control program of blind reference standards, blanks, and duplicates is used to monitor the integrity of the analytical results, with duplicate assaying performed by ALS Chemex in Vancouver, BC and Reno, Nevada. Metallurgical sample analyses were completed by ALS Chemex, with additional duplicate analyses performed by FLSmidth Dawson Metallurgical in Salt Lake City, Utah.
All exploration samples are from diamond drill core that is sawn in half at regular sample intervals or based on geologic and mineralogic contacts. Metallurgical samples use whole drill core. Gold is analyzed by fire assay with atomic absorption (AA) finish; silver is analyzed by digestion/AA, with higher grade samples repeated using metallic screen fire assay methods. Lead and zinc are analyzed by induced coupled polarization or by digestion/AA, with high grade samples repeated using titration methods.
Estimated true vein widths presented above are calculated from drilled intercept lengths and the angles of intersection between drill holes and veins. Assay results presented are the in situ metal grades, with no cutting of high grades and no metallurgical recoveries applied.
