Executive Summary
This section of the technical report details the recovery methods employed at the Rocanville mine. Potash ore has been mined and concentrated to produce saleable quantities of high-grade finished potash products since 1970. The products include granular and standard grade potash used for agriculture applications. Both flotation methods and crystallization methods are utilized to concentrate potash ore into finished potash products at the Rocanville mill.
Production data over the past three years indicates a significant increase in output, with 2017 reaching 4.587 million tonnes of finished potash products at an average grade of 60.62% K2O. Mill recovery rates over the past decade have averaged 83.8%, ranging between 81.5% and 86.0%. Quality control testing is conducted continually to optimize circuit performance and ensure product quality.
The Rocanville mill processes raw potash ore on surface, and concentrated finished potash products (near-pure KCl) are sold and shipped to markets in North America and offshore. Given the long-term experience with potash geology and actual mill recovery at Rocanville, no fundamental potash milling problems are anticipated in the foreseeable future.

Executive Summary
The Rocanville mine has been in operation since 1970, producing high-grade finished potash products for agriculture and industry. Over the past three years, production volumes ranged from approximately 2.48 million to 2.72 million tonnes of finished potash products, with an average K2O grade of approximately 60.5%. The facility processes raw potash ore on the surface to produce near-pure KCl for markets in North America and offshore.
Concentration of the potash ore is achieved through two primary methods: flotation and crystallization. These milling methods are utilized to concentrate the ore into saleable finished products. The process flow involves surface processing where raw ore is treated to separate the valuable potash minerals from waste material.
Quality control and monitoring are conducted continually to ensure continuous improvement of the milling and concentrating processes. Over the past decade, actual mill recovery rates have averaged 84.3%, ranging between 82.5% and 86.6%. Given the long-term history of potash geology and mill performance, no fundamental milling problems are anticipated in the foreseeable future.

Executive Summary
The Rocanville mine has been in continuous operation since 1970, producing high-grade finished potash products primarily for agricultural applications. The facility processes raw potash ore on the surface using a combination of flotation and crystallization methods to concentrate the material into near-pure potassium chloride (KCl) products. These finished products are distributed to markets across North America and offshore regions.
Production data from the past three years indicates stable output, with 2019, 2020, and 2021 volumes ranging between 5.001 and 5.285 million tonnes. The average grade of the finished product over this period has been approximately 60.5% K2O. Mill recovery rates have remained consistent over the last decade, averaging 83.2% with a range of 81.5% to 84.4%, suggesting no fundamental milling issues are anticipated in the near future.
Continuous quality control testing and optimization efforts are conducted at the site and Nutrien research facilities to fine-tune the milling and concentrating processes. This ongoing commitment to performance monitoring ensures product quality and operational efficiency at the Rocanville minesite.
