Yamana Gold Announces Discovery of New High-Grade Naty Zone at Cerro Moro and Significant High-Grade Results From New Exploration Drilling While Extending Exploration Program to Broader Cerro Moro

TORONTO, Nov. 19, 2019 (GLOBE NEWSWIRE) -- YAMANA GOLD INC. (TSX:YRI; NYSE:AUY) (“Yamana” or “the Company”) today announced exploration results for the Cerro Moro mine in Argentina, all of which show significant high-grade intersections in an entirely new zone and extensions of previously identified zones. These exploration results demonstrate a growing mineral resource base in new areas that are expected to establish Cerro Moro as a long-life, high-quality, high-grade gold and silver operation.

Exploration Highlights

  • Discovery of a new mineralized zone. Drill intercepts are helping to define a significant new mineralized zone along the Naty structure, located 25 kilometres south of the core mine.

  • Significant results from new exploration drilling in core mine area. High-grade intercepts in the Nini Extension, Tres Lomas, Michelle, and Deborah sectors.

  • Encountering high grades in the Martina and Escondida sectors. Select drill intercepts exceed 100 grams per tonne (“g/t”) of gold.

  • Exploration program extended to entire Cerro Moro concession. Program now covers the full 150,000-hectare land package.

The Company has committed to an initial four-year exploration program, which began in early 2018, to systematically explore Cerro Moro. The program combines soil and rock geochemistry, ground geophysics, surface geological and alteration mapping, and reconnaissance drilling. Through the third quarter of 2019, more than 9,700 soil samples and 5,300 rock samples have been analyzed, 76 line kilometres of CSAMT (controlled source audio-magnotelluric) surveys have been completed, and 23,400 metres of reconnaissance RC (reserve circulation) and diamond drilling have been completed.

The program has led to the discovery of new mineralization in several areas of the property with positive results in the core mine as well as the newly discovered Naty zone. It has also extended historically known veins not currently in the mine plan, generating new targets for additional mineral resources.

NATY ZONE DISCOVERY
The Naty zone occurs along a major property scale fault currently being explored along its 25-kilometre length. Drilling to date at 60-metre centres has defined mineralization along 400 metres of strike length. Mineralization extends to surface occurring over significant widths and remains open down a shallow plunge to the northeast, where exploration is ongoing, all of which suggests that any mining would be open pit. The mineralization consists of black silica, a known marker of high-grade mineralization at Cerro Moro, demonstrating a large footprint to the high-grade event on the property. An inferred mineral resource estimate is expected to be reported with year-end mineral resource updates. Other mineralized targets along the structure are currently being drill tested to locate further mineral resource potential.

Work to date at Naty indicates the presence of high grades with above average widths of mineralization. Among the more notable results are hole MD2925, which intersected 24.52 g/t of gold and 113 g/t silver over 4.6 metres (estimated true width), and hole MD2936, which intersected 13.74 g/t of gold and 265 g/t of silver over 2.0 metres (estimated true width). See additional drill results in Table 1 and a plan map of the Naty zone in Figure 1.

The discovery of the Naty zone and initial drill results underline the exploration potential of northeast striking district-scale fault structures on the property, which provides an important, newly recognized exploration target.

HIGH GRADE INTERCEPTS IN CORE MINE AREA
In addition to the Naty zone discovery, comprehensive surface exploration at Cerro Moro has led to the discovery of new mineralization in several areas of the property, including substantial results from the Nini Extension, and the Tres Lomas, Michelle and Deborah sectors, as shown in Table 2. The Nini Extension and Tres Lomas areas are expected to add new open pit mineral resources while drilling at Michelle and Deborah is increasing the strike length of these high-grade veins. Drilling will continue in order to define the Nini Extension at depth down plunge and test several parallel targets at Michelle.

Infill and extension drilling in the Martina, Escondida, Veronica, and other sectors also generated strong results, with gold grades above 100 g/t encountered across estimated true widths ranging up to 2.5 metres. These results define a sub-horizontal ore shoot that will be established as indicated mineral resources by year-end. Notable results include hole MD2659, which intersected 252.68 g/t of gold and 306 g/t of silver over 2.5 metres (estimated true width). This hole includes a narrower interval of 1.2 metres (estimated true width) that intersected 485.05 g/t of gold and 522 g/t of silver. Hole 2538 intersected 266.19 g/t of gold and 456 g/t of silver over 1.4 metres (estimated true width). See additional results in Table 3.

EXTENDING EXPLORATION ACROSS FULL CERRO MORO CONCESSION
Recent exploration efforts have led to the delineation of multiple district-scale fault structures on the property possessing significant displacements and strike lengths. These newly identified structures, including both northwest and northeast trends, are similar in orientation and character to structures hosting known high-grade mineralization on the Cerro Moro property. To date, four of these major structures have been delineated representing a cumulative strike length of over 40 kilometres. These structures are a focus of current exploration activities and it is anticipated that this ongoing work will generate further exploration targets in 2020. See Figure 2 for a map of core mine targets and main new zones and Figure 3 for a plan map of Cerro Moro’s major structures.

To date, exploration at Cerro Moro has focused on a 40,000-hectare northeast trending corridor extending north and south of the core mine. However, as of the third quarter of 2019, the exploration program has been expanded to encompass the entire 150,000-hectare Cerro Moro land package by initiating an airborne magnetic survey and wide-spaced soils geochemistry.
