Puna Operations

Puna Operations Inc. comprises the Chinchillas mine and the Pirquitas property, which includes the Pirquitas processing facilities. Puna Operations is located in the Jujuy Province, Argentina.

On May 31, 2017, SSR Mining formed the Puna Operations joint venture with Golden Arrow Resources Corporation for the development of the Chinchillas project. The joint venture, named Puna Operations Inc., consisted of SSR Mining’s Pirquitas property and Golden Arrow’s Chinchillas property and was owned on a 75% / 25% basis by each company, respectively. On September 18, 2019, SSR Mining completed the acquisition of the remaining 25% interest in Puna Operations Inc. With the completion of the transaction, SSR Mining now owns 100% of Puna Operations.

The Chinchillas mine is a silver-lead-zinc deposit, which achieved commercial production in December 2018. It is expected to supply ore to the Pirquitas processing facilities over an 8-year active mining period. Open pit mining is conducted using conventional drill, blast, truck and loading operations. The ore is transported 40 kilometers to the Pirquitas processing facilities, which produce a silver-lead concentrate and a zinc concentrate that are shipped to international smelters.

The Pirquitas processing facilities have been in commercial production since 2009, processing ore from the San Miguel open pit, which concluded mining activities in January 2017 and currently hosts the tailings deposit facility .

A paved roadway extends to within 47 kilometres of the plant site. Pitarrilla is a silver, lead, and zinc project, which may consist of a large open-pit mainly recovering oxidized ores in the early years of production and then predominantly sulphide ores from the deeper parts of the deposit.[2]
