Arnfinn Prugger (Ph. D., P. Geo.) – Vice President, Potash Technical Services, PotashCorp

Arnfinn immigrated to Canada with his parents in 1960, initially settling in Esterhazy, Saskatchewan, where his father worked as mining engineer and mine captain in the fledgling potash industry. The family moved to Saskatoon in 1964, where Arnfinn has lived for most of his life, graduating from Nutana Collegiate in 1975. Arnfinn completed his BSc In Geological Engineering – Geophysics Option at Queen’s University in 1982, then returned to Saskatoon to study further at U of S, completing an MSc in 1985 and a Ph.D in 1994, both in geophysics applied to rock failure related to potash mining. He has worked at PotashCorp since 1990, initially as mine geophysicist, progressing through different levels of responsibility to his current executive role. Arnfinn was involved with all technical aspects of the construction of the Scissors Creek shaft, the third shaft at PotashCorp’s Rocanville potash mine.


Scissors Creek: The First Potash Shaft Successfully Completed in Saskatchewan since 1979

The Rocanville potash mine, which is located in southeast Saskatchewan, has been in continuous production since its inception in1971. Potash is mined at approximately 1000 m depth below surface at Rocanville. In 2007 an expansion of the Rocanville mine was announced: to increase production from 3.0MMtpa to approximately 5.7MMtpa finished potash products. The Rocanville potash mine has historically been accessed through two shafts: a production and ventilation exhaust shaft, and a service and ventilation fresh air shaft. A very important part of the Rocanville expansion involved construction of a new service shaft 15km from the existing surface plant. Once this third shaft was completed in 2015, the historical service shaft was converted to a second production shaft. Three shafts are now available for mine access and ventilation at Rocanville. This presentation summarizes the construction of the new Scissors Creek shaft at the Rocanville mine, the first potash shaft successfully completed in Saskatchewan since 1979.
