Puna
Large-scale silver producer
Puna (100% SSR owned) is comprised of the Chinchillas mine and the Pirquitas property, which includes the Pirquitas processing facilities. Puna is located in the Jujuy Province, Argentina.
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.
Highlights of the operation include:
- Mineral Reserves: Proven and Probable Mineral Reserves of 31.5 million ounces of silver at an average grade of 157.7 g/t as of December 31, 2022.
- Potential for mine life extension: Measured and Indicated Mineral Resources of 18.1 million ounces of silver at an average grade of 104.8 g/t at Chinchillas and 24.8 million ounces of silver at an average grade of 292.3 g/t at Pirquitas. Inferred Mineral Resources of 446,000 ounces of silver at an average grade of 112.87 g/t at Chinchillas and 7.2 million ounces of silver at an average grade of 206.9 g/t at Pirquitas as of December 31, 2022.
- Puna operating outlook: The 2021 SK1300 Technical Report Summary life of mine plan for Puna featured 5 years of mining to 2026 including average annual production of 7.0 million ounces of silver over the first 5 years.
- Exploration potential: The puna operation features opportunities for mine life extension, including the potential for in-pit Mineral Reserve and Resource growth at the Chinchillas pit, potential for near-mine Mineral Reserve and Resource growth at the Cortaderas target, and greenfield exploration targeting across the regional Puna land package.
