Yamana Gold Provides Exploration Update on the Canadian Malartic Mine; Announces Discovery of East Gouldie Zone

09/09/2019

TORONTO, Sept. 09, 2019 (GLOBE NEWSWIRE) -- YAMANA GOLD INC. (TSX: YRI; NYSE: AUY) (“Yamana” or “the Company”) today provided an update on exploration activities at its 50% owned Canadian Malartic mine in northern Quebec.1  The Company also indicated that an exploration update is planned for each of El Peñón and Minera Florida in the fourth quarter.

Canadian Malartic Exploration Highlights:

  • Discovery of a new mineralized zone, East Gouldie. Drill intercepts are helping to define a significant new mineralized zone located south of the East Malartic zone.
  • Indicated and inferred mineral resources for East Malartic mineralized zone. East Malartic inferred mineral resources above 1,000 metres below surface showed a 14% increase between year-end 2017 and year-end 2018 to 1,403,000 ounces of contained gold (50% interest) as well as a new indicated mineral resource of 361,000 ounces of contained gold (50% interest). Inferred mineral resources at year-end 2018 below 1,000 metres totaled 1,481,000 ounces of contained gold (50% interest) and have not been previously reported.
  • Indicated and inferred mineral resources for the Odyssey mineralized zone. Indicated mineral resources at year-end 2018 totaled 68,000 ounces of contained gold (50% interest), including 63,000 ounces above 1,000 metres below surface and 5,000 ounces below 1,000 metres. Inferred mineral resources at year-end 2018 totaled 809,000 ounces (50% interest), including 449,000 ounces above 1,000 metres below surface and 360,000 ounces below 1,000 metres.
  • Odyssey Ramp. The permit allowing for the development of an underground ramp at the Odyssey project was received in December 2018.
  • Purchase of Rand Malartic. The Canadian Malartic General Partnership acquired a 100% interest in the Rand Malartic property in March 2019, which provides an additional 262 hectares adjacent to the east side of the Canadian Malartic property and has the same favourable geological setting as the Odyssey zone.

(All amounts are expressed in United States Dollars unless otherwise indicated.)

1. Yamana and Agnico Eagle Mines Limited each hold an indirect 50% interest in the Canadian Malartic mine. The mine is operated by the Canadian Malartic General Partnership under a joint management committee.

The primary objective of exploration at Canadian Malartic in 2019 is defining and increasing underground mineral resources, with a focus on Odyssey, East Malartic, and now the newly discovered East Gouldie zone. The potential exists in these areas to increase production by supplementing open pit production with higher grade underground feed and also to extend mine life.

Drilling to date has defined considerable mineral resources that continue to grow at depth, and identified a new zone which points to the potential of a larger converging mineralized zone, thereby suggesting the prospect for a large underground bulk tonnage opportunity.

East Gouldie

Drilling this year at East Gouldie, which lies south of the main East Malartic shear and dips north, has yielded a number of positive intercepts. Results indicate that the East Gouldie, East Malartic, and Sladen zones are converging at depth, increasing the level of confidence in the economic potential of overall mineral resource below 1,000 metres and, as such, contributed to the new disclosure of the updated mineral resource figures for East Malartic at year-end 2018. The deeper portions of both zones are currently being investigated with ongoing deep drilling.

Among the more notable results are the two discovery holes drilled in late 2018: MEX18-121, which intersected 3.1 grams per tonne (“g/t”) of gold over 28.0 metres (estimated true width), and MEX18-108AC, which intersected 5.5 g/t of gold over 18.1 metres (estimated true width), as well as MEX18-127W, which intersected 8.1 g/t of gold over 26.6 metres (estimated true width). Follow-up drilling in 2019 has continued to outline additional gold mineralization, highlighted by holes MEX19-140, which intersected 7.2 g/t of gold over 9.0 metres (estimated true width), and MEX19-139, which intersected 5.1 g/t of gold over 25.2 metres (estimated true width).

Mineralization at East Gouldie has been intercepted by drilling along 1,200 metres of strike over up to a 700-metre vertical extent, including across wide intercepts as demonstrated by the examples noted above. Drilling is ongoing and a preliminary inferred mineral resource is expected by year-end 2019. A summary of the main intercepts as well as a long section are provided below.

Rand Malartic

The Rand Malartic property extends 1.7 kilometres eastward along the Cadillac-Larder Lake break within the Piché Group, immediately east of the Odyssey project. The property has the same favourable geological setting as Odyssey, with several porphyry intrusions located near surface in the southernmost position of Piché volcanic rocks along the Odyssey South structure. The acquisition of Rand Malartic has allowed for further exploration both within the Rand Malartic property and in the Canadian Malartic mine boundary area. In the boundary area, infill drilling has helped define the high-grade internal Marianne zone at Odyssey. Notable results include hole ODY19-5284A, which intersected 10.1 g/t of gold over 5.39 metres (estimated true width). Within the Rand Malartic property, drilling has focused on defining porphyry-hosted mineralization in the extension of Odyssey south. The host porphyry at Odyssey is exposed at surface on the Rand Malartic claims providing both shallow open pit targets and deeper targets. The initial 2019 exploration budget of C$1.9 million for Rand Malartic has been increased to C$2.45 million (100% basis) by shifting budget priorities. To date, 14,800 metres of drilling has been completed. Preliminary drill results are promising, with select intercepts listed in Table 5 below.

While Rand Malartic has been an important focus of exploration since being acquired, exploration work also continues in the Midway and 117 zones along with a data compilation of the East Amphi project, located west of the main Canadian Malartic pit.

Progress on El Peñón and Minera Florida

Exploration at El Peñón continues to replace depletion with new discoveries in the core mine and in satellite deposits. Recently identified faults have been determined to displace extensions of previously mined ore bodies. New significant drill intersections on the Orito vein at depth resulting from this interpretation continue to be tested and plans are in progress to test this model at other principal veins.

At Minera Florida, with underground access now established, drilling continues to confirm new areas of mineralization which are expected to lead to mineral resource increases.

An exploration update is planned for each of El Peñón and Minera Florida in the fourth quarter.
