TORONTO, May 19, 2020 (GLOBE NEWSWIRE) — YAMANA GOLD INC. (TSX:YRI; NYSE:AUY) (“Yamana” or “the Company”) today provided an update on exploration results for the Jacobina and El Peñón mines. Results at both operations continued to show growth in mineral reserves and mineral resource through year-end 2019 with additional promising new exploration results in the first quarter of 2020.Exploration Highlights, JacobinaExploration at Jacobina in the second half of 2019 through the first quarter of 2020 expanded higher grade zones in Canavieiras Sul, both down dip and along strike to the north towards Canavieiras Central, providing significant expansion of the known mineralized zone in the highest grade sector of the mine. 
 Drilling down plunge of known high grade mineralization at Morro do Vento intercepted higher grades over good widths indicating excellent mineral resource expansion potential in this sector.
 Exploratory drilling continues to demonstrate the potential of the João Belo Sul area adjacent to the João Belo mine, as well as at Morro da Viuva, located about one kilometre north of Canavieiras.
 Surface exploration in the Serra Branca target area, located 12 kilometres north of Canavieiras, has returned significant gold results from surface sampling along a strike length of more than 2.0 kilometres.SignificanceThe exploration results, at minimum, support the extended mine plan scenario (“Extended Case”) highlighted in the Company’s recent announcement on the Phase 2 expansion of Jacobina (see press release dated May 6, 2020, available on the Company’s website at www.yamana.com). The Extended Case, which considers the addition of 9.5 million tonnes of plant feed, based on conversion of current mineral resources, with an average grade of 2.40 grams of gold per tonne (“g/t”), is the Company’s new base case. Mine life under this scenario is forecast at 14.5 years, however, Jacobina has a long track record of increasing mine life and the latest exploration results underscore the likelihood that mine life will increase further under the Extended Case scenario at the contemplated throughput of 8,500 tonnes per day (“tpd”). In addition, these results highlight the potential to bring higher grade areas into production earlier in the operation’s mine life.Exploration Highlights, El PeñónDrilling at El Peñón in the fourth quarter of 2019 through the first quarter of 2020 intercepted encouraging mineralization at depth below existing mineral resources at the Bonanza, Sorpresa, and Pampa Campamento veins, as well as along strike at the Esmeralda vein, with all four veins demonstrating excellent potential for further mineral resource growth.
 Drilling at depth below mineral resources at Pampa Campamento has delivered good results, including drill hole UIP0003 with 6.0 g/t of gold and 189 g/t of silver over a horizontal width of 2.1 metres. At the Bonanza vein, deeper drilling in widely-spaced holes has also returned encouraging results, including hole UEB0028, with 9.1 g/t of gold and 167 g/t of silver over a horizontal width of 1.1 metres.
 Exploration drilling in 2019 on the Sorpresa vein demonstrated mineralization in a gap in mineral resources, where both infill drilling and testing in the area down plunge has returned promising results.
 At the Esmeralda vein, a secondary vein parallel to the prolific Bonanza structure, drilling has indicated good potential for extensions to the south of known mineral reserves. 
 Surface exploration in the El Peñón district continued to generate drill targets for further exploration, such as the Cerro Seco area, a new zone located immediately adjacent to the core mine vein system that may reflect a continuation of the same vein geometry as the core mine.SignificanceThe discovery of new secondary veins along with extensions and offshoots of primary veins further underscore the resilience and potential of the vein system at El Peñón. The results support the Company’s view that mine life will exceed current mineral reserves and is at least consistent with the Strategic Life of Mine of at least 10 years. Furthermore, because El Peñón has excess plant capacity, the discovery of extensions of primary vein structures provides flexibility to process more tonnage at higher grades, which would increase annual production. Jacobina Exploration UpdateExploration drilling at Canavieiras Sul in the second half of 2019 and the first quarter of 2020 expanded the known zones by 125 metres down dip, and infill drilling in 2020 is expected to provide new mineral resources with excellent intercepts in the LU, MU, and LVLPC reefs. Notable results include the following estimated true width intervals: 10.5 g/t of gold over 5.4 metres (CAS492); 5.3 g/t of gold over 3.4 metres (CAS473); 4.8 g/t of gold over 4.2 metres (CAS471); 3.4 g/t of gold over 9.5 metres (CANEX60A); and 3.4 g/t of gold over 2.7 metres (CANEX86).Along strike to the north, exploratory drilling towards Canavieiras Central yielded several new narrow but higher grade intercepts along a 300-metre-long extension of this high grade zone in the Maneira and LU reefs, including the following estimated true width intervals: 8.7 g/t of gold over 0.4 metres (CANEX50) and 5.6 g/t of gold over 0.4 metres (CANEX59).  See Figure 2 for additional results.Successful infill drilling on Canavieiras Central continues to generate higher grade results in the LU, MU, and LVLPC reefs with the following estimated true width intercepts: 54.7 g/t of gold over 3.0 metres (CANEX79); 6.7 g/t of gold over 3.9 metres (CANEX75); and 18.3 g/t of gold over 4.9 metres (CANEX55). Along strike to the south, exploration drilling towards Canavieiras Sul confirmed the presence of the MU reef, with an estimated true width intercept of 18.0 g/t of gold over 3.9 metres (CANEX87), opening up 180 metres of strike potential, as well as indicating down plunge continuity, to be explored. See Figure 2 and Table 1 for these and additional results. These results will also be incorporated in the updated mineral resources by year-end.The Morro do Vento sector also continues to provide excellent results and show high potential as a new area for mineral reserve growth. Ongoing exploration drilling on a high grade shoot at Morro do Vento has defined the down plunge continuation of the Main, Hangingwall, and Footwall reefs with the following estimated true width intercepts: 7.4 g/t of gold over 5.5 metres (MVTEX46); 8.4 g/t of gold over 2.3 metres (MVTEX32); and 4.9 g/t of gold over 3.3 metres (MVTEX43). See Figure 3 and Table 1 for additional results.     Exploratory drilling continues to demonstrate the potential of the João Belo Sul area adjacent to the João Belo mine, as well as at Morro da Viuva, located about one kilometre north of Canavieiras, extending the known mineralized envelope to both the north and south of the Jacobina mine. See Figures 1 and 4 and Table 1 for additional results.Surface exploration in the Serra Branca target area, located 12 kilometres north of Canavieiras, has returned significant gold results from surface sampling along a strike length of more than 2.0 kilometres, advancing this area to the drill-ready stage. The Serra Branca target is part of the larger, highly prospective Jacobina Norte project, which is located in close proximity to existing Jacobina mine infrastructure. See Figure 5 for Serra Branca results.Overall, these exploration and infill drilling results suggest a significant expansion of both mineral reserves and mineral resources within the Canavieiras and Morro do Vento sectors by the end of 2020, while new potential in the João Belo and Morro da Viuva sectors indicate excellent potential for expansion of inferred mineral resources.The results, at minimum, support the Extended Case scenario highlighted in the Company’s recent announcement on the Phase 2 expansion of Jacobina (see press release dated May 6, 2020, available on the Company’s website at www.yamana.com). The Extended Case, which includes 9.5 million tonnes of additional plant feed with an average grade of 2.40 g/t of gold, based on conversion of current mineral reserves, is the Company’s new base case. Under this scenario, the after-tax net present value (“NPV”)⁽¹⁾ increases to $993 million assuming a $1,250 per ounce gold price and a BRL/USD exchange rate of 4.0:1. NPV⁽¹⁾ increases to $1.78 billion at a gold price of $1,550 per ounce and a 5.0:1 BRL/USD exchange rate. While the Phase 2 pre-feasibility study shows a mine life of 14.5 years for the Extended Case, Jacobina has a long track record of increasing mine life and the latest exploration results underscore the likelihood that mine life will increase further under the Extended Case scenario at the 8,500 tpd throughput contemplated in the Phase 2 expansion. In addition, these results highlight the potential to bring higher grade areas into production earlier in the operation’s mine life.Figure 1: Jacobina Location Map Showing Main Target Areas and Mines.

New drill results on the Pampa Campamento, Bonanza, and Sorpresa veins have all indicated potential to extend to depths either below low-angle fault offsets or in the footwall to the Peñón rhyolite. Drill intercepts on the Esmeralda vein, a secondary vein parallel to the prolific Bonanza structure, have indicated good potential for extensions south of known mineral reserves.Drilling at depth below current mineral resources at Pampa Campamento has delivered good results, including the following intercepts reported over the following horizontal widths: 6.0 g/t of gold and 189 g/t of silver over 2.1 metres (UIP0003); and 6.9 g/t of gold and 55 g/t of silver over 1.0 metres in (UEP0014). These intercepts open up over 100 metres of strike extending at depth. See Figure 7 for additional drill results.Drill hole UEB0026, which tested the deeper parts of the Bonanza/Aleste vein system below the favourable Peñón rhyolite, intersected 19.0 g/t of gold and 50 g/t of silver over a horizontal width of 0.73 metres (11.5 g/t of gold and 30 g/t of silver diluted over a minimum mining width of 1.2 metres). Drill hole UEB0028, which intersects the Bonanza/Aleste vein 500 metres to the south of UEB0026, returned 9.1 g/t of gold and 167 g/t of silver over a horizontal width of 1.1 metres, opening up significant potential for further mineralization at depth in this highly productive vein structure. The Bonanza/Aleste vein structure was the last primary vein structure discovered and developed by the Company and, as such, a discovery of a meaningful extension would be significant and very prospective.  As a very high grade vein structure, Bonanza/Aleste produced 1.12 million ounces of gold and 20.92 million ounces of silver (approximately 1.4 million gold equivalent ounces using the prevailing gold to silver ratio of the time) from 2009 through early 2018. See Figure 8 for additional drill results.Exploration drilling in 2019 on the Sorpresa vein demonstrated mineralization in a gap in mineral resources in this vein, while infill drilling and testing of the area down plunge returned promising results, including some holes with wider mineralized intervals, such as: SSI0062, returning 5.9 g/t of gold and 342 g/t of silver over a horizontal width of 4.9 metres and drill hole SSI0064 with 7.0 g/t of gold and 287 g/t of silver over a horizontal width of 1.8 metres. These targets remain open at depth and will be further drill tested during 2020. See Figure 9 for additional drill results.Esmeralda is a secondary vein adjacent to Bonanza that, to date, has demonstrated limited down dip extent, but recent drilling indicates that the structure remains open along strike with stepouts to the south. Results include hole SEE0016 with 8.6 g/t of gold and 333 g/t of silver over a horizontal width of 0.7 metres (5.0 g/t of gold and 194 g/t of silver diluted over a minimum mining width of 1.2 metres). See Figure 10 for additional details. Infill drilling 400 metres to the north continues to produce good results in Esmeralda Central as shown in Table 2.Surface exploration at El Peñón has expanded since the start of the fourth quarter with soil and rock sampling and mapping of select targets originally generated by a machine learning study completed in 2019. Soil anomalies with gold and pathfinder metals are helping generate drill targets for further exploration, such as the Cerro Seco area, a new zone located immediately adjacent to the core mine vein system. See Figure 11 for a diagram of Cerro Seco soil geochemistry and proposed drill holes. This anomaly, in an area previously considered to have low potential, may reflect a continuation of the en-echelon core mine vein system.The discovery of new secondary veins along with extensions and offshoots of primary veins further underscore the resilience and potential of the vein system at El Peñón. The results support the Company’s view that mine life will exceed current mineral reserves and is at least consistent with the Strategic Life of Mine of at least 10 years. Furthermore, because El Peñón has excess plant capacity, the discovery of extensions of primary vein structures provides flexibility to process more tonnage at higher grades, which would increase annual production. At El Peñón, with more than 5.0 million ounces of gold production to date, exploration efforts continue a 20-plus year history of replacing depletion and adding new mineral resources to this prolific asset. Exploration results through the end of the first quarter of 2020 indicate further exploration success can be anticipated.Figure 6: El Peñón Property Location Map. Star Symbol Indicates Location of Mine Plant Facility.
