Dennis O’Rourke – Chairman

Dennis purchased Sil Industrial Minerals in 2004 after identifying an opportunity to expand his expertise and promote the use of Alberta’s natural resources. Dennis’s passion for Alberta and its resources started when founding the Sureway Construction Group Ltd. in 1973, which he grew into one of Western Canada’s leading construction groups.
Dennis is known among his peers as a pioneer, innovator, and risk taker who thrives on challenges. He has consistently shaped a competitive edge for his corporations by securing the latest, largest, and most productive assets in the industry.

Known to be a generous corporate and community citizen, Dennis prefers to keep a low profile while donating both time and money to numerous educational and charitable organizations and causes. These include the Alberta Cancer Foundation, Notre Dame College, The Alberta Heart Institute, the University Hospital Foundation, STARS, CNIB, University of Alberta, Capital Care Foundation, Kids for Cancer, YMCA, and many others.

Marlea Sleeman – President

Marlea has been with Sil since it was acquired in 2004, and with the related corporate group for over 25 years, and her energy and commitment to quality have been steadfast through her whole career. Over the years, Marlea has honed her skills in many company departments, including finance, asset planning, estimating, project management, process technology design and implementation, logistics, and product line development.

Her ambition and strategic mindset earned her an executive role at Sil Industrial Minerals. Marlea is a dedicated member at a number of industry associations, including National Stone, Sand and Gravel Association (NSSGA), Alberta Enterprise Group (AEG), Urban Development Institute (UDI) Edmonton, and Canadian Manufacturers and Exporters Association (CME). She volunteers on the boards of NSSGA and AEG.
