Yamana Gold Provides An Exploration Update

TORONTO, ONTARIO--(Marketwired - Feb. 14, 2017) - YAMANA GOLD INC. (TSX:YRI)(NYSE:AUY) ("Yamana" or "the Company") herein provides an update on the exploration programs at its El Peñón, Minera Florida, Gualcamayo and Chapada properties.

EL PEÑÓN, CHILE

One of the primary goals of the 2016 exploration program at El Peñón was to find another principle structure similar to Quebrada Orito, Quebrada Colorada or Bonanza. The main targets in the northern and southern blocks of the property returned some encouraging results, with several narrow yet high grade intercepts indicating the continuation of the mineral system at both extents of the property. One area with promising success identified high-grade moderate-width intercepts beneath the Quebrada Colorada and Providencia structures that are open to depth and along strike. During the late third and into the fourth quarter of 2016, similar high grade extensions on the northern extents of the Bonanza system were also identified.

Highlighted assay results received during the fourth quarter of 2016 from exploration holes include:

Quebrada Colorada

  • SNX0750 that intersected 1.8 metres of 30.36 grams per tonne ("g/t") Au and 109 g/t Ag at Carmin Sur;
  • SNX0764 that intersected 1.2 metres of 5.73 g/t Au and 1,579.0 g/t Ag at Purpura;
  • UIG0028 that intersected 0.8 metres of 9.76 g/t Au and 79.0 g/t Ag at Magenta; and
  • UIG0037 that intersected 1.07 metres of 5.0 g/t Au and 194.0 g/t Ag at Magenta.

Providencia

  • UER0114 that intersected 1.1 metre of 30.0 g/t Au and 1,267.0 g/t Ag;
  • UER0117 that intersected 1.2 metres of 2.6 g/t Au and 184.0 g/t Ag; and
  • UER0121 that intersected 1.96 metres of 24.4 g/t Au and 438.0 g/t Ag.

Bonanza

  • UEB0014 that intersected 1.25 metres of 5.4 g/t Au and 15.8 g/t Ag;
  • UEB0016 that intersected 2.6 metres of 7.6 g/t Au and 340 g/t Ag at Bonanza Norte; and
  • UEB0018 that intersected 2.8 metres of 9.8 g/t Au and 11.0 g/t Ag at Bonanza Central.

As examples of the potential impact of the drilling, Quebrada Colorada hole SNX0750 is expected to upgrade Inferred Mineral Resources discovered in 2016 to Indicated Mineral Resource status over a 100 metre vertical extent and Bonanza hole UEB0014 has extended mineralization 200 metres along strike and up to 120 metres in vertical extent. Tables 1, 2, 3 and 4 provided at the end of this press release summarize the drill intercepts relating to the El Peñón drilling campaign.

While the Company continued its efforts to discover a new principle vein system in the North Block at El Peñón during 2016 (Figure 1), numerous smaller and narrower high grade zones at depth and near the surface expressions of Quebrada Colorada (Figure 2), Bonanza, Quebrada Orito and elsewhere were discovered and became the focus of the exploration program during the third and fourth quarters of 2016.

Narrow mining techniques which were tested and confirmed on "test case" narrow veins have shown economic extraction is possible from these vein systems, although at reduced production levels.

Exploration during the first half of 2017 will concentrate on exploring for additional vein extensions surrounding the established and highly productive principle vein systems. This near mine program will be augmented with a local exploration effort in the second half of the year to explore for deep extensions to the south of the Aleste, Providencia and Dorada vein systems.

Figure 2: Long section of the Carmin Sur (Quebrada Colorada) vein segment with locations of recent drill results - http://media3.marketwire.com/docs/1085764fig2.pdf.

The Company believes that 2017 will be a year of transition at El Peñón with the available wide and high grade veins being replaced by numerous high grade yet narrower vein systems. During this transition, production will be reduced from recent levels, although over a longer term at a more sustainable level. The Company also expects that all-in sustaining cash costs will improve to lower levels as much of the future production is near existing infrastructure requiring less development capital. Exploration will concentrate on near mine discovery and growth, and will continue over a longer term to execute a local and district exploration program for another large vein discovery that can sustain and possibly return long-term production to pre-2017 levels.

MINERA FLORIDA, CHILE

At Minera Florida, exploration activities in 2016 changed from a focus on infill and Mineral Reserve replacement in 2015 to a focus on Mineral Resource discovery and growth. For 2016, the focus was on extending known deposits in the core mine areas along strike and to depth, and venturing into new areas outside of the core mine area to develop mineral anomalies identified in prior exploration programs. In 2017, the program will follow up on significant surface exploration mapping and sampling completed in 2015 and 2016 given some success in identifying numerous quartz vein trends and gold anomalies that are proposed to be linked to producing vein structures at depth.

As announced in the Company's exploration update dated October 27, 2016, Yamana acquired control of the entire Minera Florida district which provides access to previously unexplored ground immediately south and southeast of the mine area.

The Las Pataguas target was developed in late 2016 through district mapping and geochemical sampling. The deposit is within the core mine complex, proximal to existing mine infrastructure. It is at a lower elevation and closer to the plant infrastructure than the current mine working (Figure 3). Anomalous chip samples collected on northwest trending silicified outcrops identified this 1.2 kilometre trend as a high priority target (Table 5). Hole CLDFDH0018 targeted the Las Pataguas vein with success, intersecting 16 metres of 7.77 g/t Au at the 830 metre elevation. Follow-up hole CLDFDH0019, was drilled to test beneath CLDFDH0018 but deviated downward and missed the favourably mineralized elevation. The subsequent holes were targeted to test offsets to the discovery hole along strike and near the surface, all with very encouraging assay and visual results (Figure 4). Table 5 included at the end of this press release shows the list of all assay results to date developed on the Las Pataguas vein system.

Figure 3: The Las Pataguas Vein is located one kilometre west of the core mine workings and can be exploited from the Hornitos Tunnel which is closer and at a lower elevation than the current production tunnel - http://media3.marketwire.com/docs/1085764figure3.pdf.

Figure 4: Plan view of the Las Pataguas target shows vein segments in red and drill hole traces in light blue, mapped vein surface exposures in red - http://media3.marketwire.com/docs/1085764figure4.pdf.

The Company believes that the Las Pataguas system is the most important discovery at Minera Florida in the past 10 years and as currently defined by drill intercepts, measures approximately 250 metres vertically by 350 metres along strike. The deposit remains open in all directions and can be expected to significantly grow during the 2017 drill program. A cross section of the Las Pataguas target is provided in Figure 5 below.

Figure 5: Northwest to southeast oriented cross section of Las Pataguas showing assay contoured drill hole intercepts - http://media3.marketwire.com/docs/1085764figure5.pdf.

The Las Pataguas system is only one of numerous geochemical and alteration vein anomalies identified on the newly acquired ground. Vein structures along the Mila-Volga corridor, down dropped vein offsets of historically mined veins east of the Maqui Fault, are targeted for testing in 2017 from the newly developed exploration tunnel and from surface.

While the initial objective is to increase mine life, a further objective will be to take advantage of current plant capacity, which is under utilized, to increase production. To address this excess capacity, the Company plans to extend the permitted Hornitos production tunnel beneath the Las Pataguas and other systems over the next two years. Once completed, this will allow for production to be sourced from two production tunnels, providing the opportunity to fill the excess plant capacity and increase the production levels at Minera Florida.

GUALCAMAYO, ARGENTINA

At Gualcamayo, exploration drilling, that commenced in late 2015 to discover and develop new oxide ounces amenable to current heap leach processing facilities continued into 2016. The drilling focused on near mine targets, including Cerro Condor, Potenciales and Las Vacas (Figure 6) and included the collection of 10-metre channel samples for geochemical analysis.

Drilling during the course of 2016 included 5,795 metres distributed in 28 holes testing the Potenciales target, 4,359 metres distributed in 19 holes testing the Las Vacas target, 3,198 metres distributed in 20 holes testing the Cerro Condor target and 4,946 metres distributed in 19 holes that tested the Target 9 and AIM targets.

As reported in the Company's October 27, 2016 press release, positive results were returned from two areas immediately adjacent to the current open pit. The Cerro Condor target is located along the eastern rim of the QDD Main pit wall and was defined by channel sample results including 60 metres of 2.57 g/t Au and 10 metres of 9.19 g/t Au. Hole 16QD-975 drilled in September returned 104 metres of 1.41 g/t Au. The Potenciales target, located along the western flank of the pit wall, was defined by numerous channel sample results, including 10 metres of 10.5 g/t Au and 10 metres of 13.28 g/t Au.

Figure 6: Plan view image of the Gualcamayo Mine open pit and close in exploration targets Las Vacas, Cerro Condor and Potenciales - http://media3.marketwire.com/docs/1085764figure6.pdf.

Follow-up drill results for Cerro Condor, Potenciales and a third near surface oxide target, Las Vacas from drilling conducted in the fourth quarter, continue to support Mineral Resource growth from these near mine target areas. Tables 6, 7, and 8 included at the end of this press release provide all drill results received for Potenciales, Cerro Condor and Las Vacas since the Company's October 27, 2016 exploration press release. At Cerro Condor, the currently defined mineral body measures 190 metres long by 90 metres wide and at least 65 metres thick, averaging 1.1 g/t Au (Figures 7 and 8). Late 2016 drill results are pending and this mineral body is expected to grow once the results are received. The Potenciales target's currently defined shape stands at 150 metres in length by 50 metres wide by 80 metres depth averaging 1.0 g/t Au and is open to depth. The Las Vacas deposit is at least 500 metres along strike, 200 metres wide and 200 metres in depth, averaging 0.6 g/t Au and remains open along strike. Exploration and infill programs for 2017 will continue work on these targets to support Mineral Resource growth, and will also begin to develop the near mine targets such as the "truck shop" target, the SalidaAlaya, Quebrada Aspera and other targets supported by gold anomalies found in calcareous hydrothermal breccia.

Figure 8: Sectional view of Cerro Condor showing growth of the mineral body as a result of fourth quarter 2016 drilling - http://media3.marketwire.com/docs/1085764figure8.pdf.

A 2.7 kilometre access road from Las Vacas to the near mine Quebrada de Rodado area was completed and sampled during the fourth quarter of 2016, exposing new geologic and geochemical targets to be drill tested in early 2017. District exploration efforts will include gaining access to favourable target areas beginning close to the mine and working our way west and to the south. As evidenced by the ongoing discoveries at deep carbonates and recent near mine discoveries in 2015 and 2016, the Company believes that a focused and concerted effort to explore the many surface geochemical, Aster and geologic targets will lead to discovery of additional mineable gold deposits that can be rapidly put into the life of mine plan.

CHAPADA, BRAZIL

The Company completed 23,610 metres of drilling in 390 holes in the near mine exploration and core mine infill programs during the fourth quarter of 2016, and a total of 61,972 metres of drilling in 753 holes over the course of the year. The near mine program focused on defining and expanding the Sucupira Mineral Resource immediately adjacent to the main Chapada pit, testing and developing an IP anomaly immediately beneath the pit and testing for extensions of the oxide mineral envelopes at Suruca and Hidrothermalito.

At Sucupira, 110 drill holes have been completed and have defined a mineralized body 1.85 kilometres in strike length, 80 to 180 metres in thickness and 200 to 400 metres in width. The deposit remains open to the southwest. The mineral body has an Inferred Mineral Resource of 490,000 ounces of gold and 426 million pounds of copper contained in 34.99 million tonnes at an average grade of 0.756% Copper Equivalent ("CuEq"), at a 0.507% CuEq underground cutoff grade (CuEq is equal to g/t gold grade multiplied by 0.504 plus percent copper). This mineralization lies within 100 to 200 metres of surface and 100 metres lateral and below the currently designed final Chapada pit (Table 9).

Adjacent to Sucupira and the main Chapada ore body, the core mine exploration program has discovered a new continuous, low to moderate grade copper and gold mineral body ("Baru") above and immediately north of the Sucupira mineral body. The newly discovered Baru target is under review by mine geologists and engineers for further work, particularly given its proximity to the plant infrastructure. Figure 9 below provides a plan view of the Chapada pit area with the Sucupira and Baru tagets highlighted. As currently defined Baru is a flat tabular sub-horizontal mineral body that is very near surface with 50 to 100 metres of low to moderate grade copper and gold mineralization. Figure 10 below shows the location of Baru relative to Sucupira. The mineral body is approximately 1.0 kilometre in length by 400 metres in width and is open to the southwest and to the north and south (Table 10). Assay results include 74 metres of 0.10 g/t Au and 0.30% Cu from 74 metres depth (NM-208) and 99 metres of 0.1 g/t Au and 0.24% Cu from 94 metres depth (NM-212). The impact of this new discovery in relation to the mineability of Sucupira, including the potential near term production impact of Baru, will be the subject of engineering studies during 2017 and 2018.

Figure 9: Plan view of Sucupira mineral body in yellow and green superimposed on an aerial photo of the Chapada main pit and low grade stock piles. The newly discovered Baru deposit is outlined in red and is open to the southwest - http://media3.marketwire.com/docs/1085764figure9.pdf.

Figure 10: Northwest to southeast cross section showing the location of the Baru deposit (yellow dashed line) relative to the Sucupira deposit - http://media3.marketwire.com/docs/1085764figure10.pdf.

The discovery of Sucupira and Baru imply that Chapada is a much larger mineralized system than previously thought. Additional drilling at Baru and engineering at Sucupira in 2017 will be completed to better understand how the three deposits may connect and/or be integrated into a future mine plan.

At Suruca, over 500 holes have been completed as part of an infill program to update the oxide Mineral Reserves and support a development plan. Suruca is an open pit heap leach operation that will process an estimated 4.3 million tonnes per annum producing an average of 40,000 ounces of gold per year over a five year life of mine.

The district exploration program at Chapada is targeting the discovery of new deposits within the extensive concession holdings surrounding the Chapada deposit and exploring holdings distal to the Chapada Mine which present similar geologic, geochemical and geophysical characteristics within the Mara Rosa Greenstone Belt. The program has completed 3,177 metres distributed in 18 holes during the fourth quarter and 9,833 metres distributed in 61 holes during 2016.

During the fourth quarter, drilling focused on the newly discovered Formiga target located 15 to 18 kilometres northeast of the mine, the Suruca NE target, 11 kilometres northeast of the mine and the Bom Jesus target, 20 kilometres northeast of the mine.

The Formiga copper-gold mineralization occurs as a high grade core of copper and gold, commonly presented as massive chalcopyrite accompanied by varying amounts of disseminated bornite, pyrrhotite and pyrite, enveloped by a low grade halo of copper and gold mineralization, similar in geometry to Sucupira. Exploration drill testing of the Formiga target during the third and fourth quarters of 2016 identified a second disseminated copper and gold deposit trending east-west with grades and alteration similar to those found within the Chapada main pit. Figure 11 below shows the location of the drilling at Formiga along with geology and soil sample results. Results to date include 20.25 metres of 1.2 g/t Au and 0.45% Cu from 64.75 metres depth in FOR-018 and 24.17metres of 0.34 g/t Au and 0.34% Cu from 118.83 metres depth in FOR-020. Table 11 included at the end of this press release provides all assay results received for Formiga since the Company's October 27, 2016 press release.

Initial results from hole FOR-003 include 2.2 metres of 0.10 g/t Au and 0.28% Cu over 3.0 metres including 1.0 metre of 0.02 g/t Au and 0.60% Cu and a second interval of 7.03 metres of 0.07 g/t Au and 0.64% Cu including 4.34 metres of 0.08 g/t Au and 0.91% Cu from 23 metres depth. Follow-up hole FOR-005 intersected several intervals, including 2.60 metres of 0.22 g/t Au, 6.59% Cu and 22 g/t Ag from 40.3 metres depth and 0.97 metres of 0.10 g/t Au and 1.0% Cu from 44.3 metres depth. The deposit occurs within similar meta-diorite and meta-sedimentary sequences to those found at the Chapada complex.

Currently, the two deposits and associated soil anomalies occur along a 3.2 kilometre long northeast to southwest trend up to 1.0 kilometre in width. In addition, a third copper gold soil anomaly of approximately 4.5 kilometres in length and 1.0 kilometre in width was identified during 2016 and initial drill testing commenced in the fourth quarter.

Figure 11: Formiga drill hole location map with geology and soil sample results - http://media3.marketwire.com/docs/1085764figure11.pdf.

The Formiga and Baru discoveries provide further evidence that the Chapada Mine is located in a highly mineralized and prospective mineral belt that continues to reveal new mineralization through systematic and thorough exploration efforts. These near and distal discoveries at and adjacent to the Chapada Mine Complex are under evaluation as to how they will impact the current life of mine plan. Possible impacts could include production increases, an extended mine life, or both.

Quality Assurance and Quality Control

Yamana incorporates a Quality Assurance and Quality Control ("QA/QC") program for all of its mines and exploration projects which conforms to industry best practices.

Samples are transported in security sealed bags for preparation at ALS Laboratories facility located in Santiago (the primary lab), ISO 9001:2008 certified and independent of Yamana. The pulps are subsequently shipped to the same laboratory located in Lima, Perú (the primary lab) for analysis, ISO 9001:2008 and 17025 certified (fire assay with AAS/gravimetric finish and multi acid digestion ICP finish). From August samples are analyzed in ALS Santiago, Chile.

Pulps checks are carried out in Bureau Veritas facility located in Santiago, Chile (the check lab), ISO 9001:2008 certified.

All samples are initially assayed by gold fire assay with 30g aliquot and AAS finish and samples over 5g/t are re-analyzed by gravimetric finish methods. All samples are analyzed by silver, lead, copper and zinc with a four acid digestion ICP-ES/AAS finish (ore level) and over limits are done by the same digestion AAS finish or gravimetric finish for Silver.

All exploration diamond drill cores are split in half by mechanical sawing technique and sampled at appropriate intervals for assay. The remaining core, field reject and pulps are stored on-site in a secure location.

Quality assurance standards, duplicates, sterile and blanks are routinely inserted into the sample stream as a control for assay accuracy, bias, precision and contamination. The results of these checks are tracked and failures are re-analyzed. This information also includes pulp checks carried out in the secondary lab.

Results are incorporated into Mineral Resource models following approval of the QA/QC local manager.

CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS: This news release contains or incorporates by reference "forward-looking statements" and "forward-looking information" under applicable Canadian securities legislation within the meaning of the United States Private Securities Litigation Reform Act of 1995. Forward-looking information includes, but is not limited to information with respect to the Company's strategy, plans or future financial or operating performance, the potential for future additions to Mineral Resources and Mineral Reserves, expected upgrades from Inferred Mineral Resources to Indicated Mineral Resources, expected reduction in AISC, plans to increase mine life and increase production, expected exploration results, and mine extensions. Forward-looking statements are characterized by words such as "plan," "expect", "budget", "target", "project", "intend", "believe", "anticipate", "estimate" and other similar words, or statements that certain events or conditions "may" or "will" occur. Forward-looking statements are based on the opinions, assumptions and estimates of management considered reasonable at the date the statements are made, and are inherently subject to a variety of risks and uncertainties and other known and unknown factors that could cause actual events or results to differ materially from those projected in the forward-looking statements.

These factors include the Company's expectations in connection with the production and exploration, development and expansion plans at the Company's projects discussed herein being met, the impact of proposed optimizations at the Company's projects, the impact of the proposed new mining law in Brazil, the new Chilean tax reform package, and the impact of general business and economic conditions, global liquidity and credit availability on the timing of cash flows and the values of assets and liabilities based on projected future conditions, fluctuating metal prices (such as gold, copper, silver and zinc), currency exchange rates (such as the Brazilian real, the Chilean peso, and the Argentine peso versus the United States dollar), the impact of inflation, possible variations in ore grade or recovery rates, changes in the Company's hedging program, changes in accounting policies, changes in Mineral Resources and Mineral Reserves, risks related to asset disposition, risks related to metal purchase agreements, risks related to acquisitions, changes in project parametres as plans continue to be refined, changes in project development, construction, production and commissioning time frames, unanticipated costs and expenses, higher prices for fuel, steel, power, labour and other consumables contributing to higher costs and general risks of the mining industry, failure of plant, equipment or processes to operate as anticipated, unexpected changes in mine life, final pricing for concentrate sales, unanticipated results of future studies, seasonality and unanticipated weather changes, costs and timing of the development of new deposits, success of exploration activities, permitting timelines, government regulation and the risk of government expropriation or nationalization of mining operations, risks related to relying on local advisors and consultants in foreign jurisdictions, environmental risks, unanticipated reclamation expenses, risks relating to joint venture operations, title disputes or claims, limitations on insurance coverage and timing and possible outcome of pending and outstanding litigation and labour disputes, risks related to enforcing legal rights in foreign jurisdictions, as well as those risk factors discussed or referred to herein and in the Company's Annual Information Form filed with the securities regulatory authorities in all provinces of Canada and available at www.sedar.com, and the Company's Annual Report on Form 40-F filed with the United States Securities and Exchange Commission. Although the Company has attempted to identify important factors that could cause actual actions, events or results to differ materially from those described in forward-looking statements, there may be other factors that cause actions, events or results not to be anticipated, estimated or intended.

There can be no assurance that forward-looking statements will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. The Company undertakes no obligation to update forward-looking statements if circumstances or management's estimates, assumptions or opinions should change, except as required by applicable law. The reader is cautioned not to place undue reliance on forward-looking statements.

CAUTIONARY NOTE TO UNITED STATES INVESTORS CONCERNING ESTIMATES OF MEASURED, INDICATED AND INFERRED MINERAL RESOURCES

This news release uses the terms "Mineral Resource", "Measured Mineral Resource", "Indicated Mineral Resource" and "Inferred Mineral Resource" are defined in and required to be disclosed by National Instrument 43-101. However, these terms are not defined terms under Industry Guide 7 and are not permitted to be used in reports and registration statements of United States companies filed with the Commission. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into Mineral Reserves. "Inferred Mineral Resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Investors are cautioned not to assume that all or any part of an Inferred Mineral Resource exists or is economically or legally mineable. Disclosure of "contained ounces" in a Mineral Resource is permitted disclosure under Canadian regulations. In contrast, the Commission only permits U.S. companies to report mineralization that does not constitute "Mineral Reserves" by Commission standards as in place tonnage and grade without reference to unit measures. Accordingly, information contained in this news release may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements under the United States federal securities laws and the rules and regulations of the Commission thereunder.
