Aggregates are rock products like sand and gravel. Although non-renewable natural resources, they are crucial to the construction of modern infrastructure such as roads, bridges, homes, and buildings. Each Albertan uses 10-15 tonnes of aggregate per year and estimated provincial consumption is 42-62 million metric tonnes per year (from ASGA).

Aggregate operations are the various activities associated with recovering material from the ground and creating a product that can be used in our everyday lives. This can include extraction (digging), crushing (sizing), screening (sorting), and washing (cleaning) of aggregates.

The Scott Property site is being considered for an aggregate operation primarily because of the high quality and quantity of aggregate resources at this location. Other factors that support this aggregate operation are:

  • Accessibility: A proposed conveyor system can transport the aggregate resources to the nearby Spy Hill operation thereby reducing community impacts, GHG emissions and impacts on local infrastructure.
  • Close to Customers: The deposit is situated in a major metropolitan area that requires aggregates to support forecasted growth. The population of the region is anticipated to double over the next 50 years. 
  • Efficiencies: Close-to-market aggregate sources mean lower costs for consumers, reduced greenhouse gas emissions, and reduced truck traffic.
  • Environmental Capabilities: Environmental studies suggest that the project can be designed in a way that will meet applicable environmental regulations, policies and standards. Heidelberg is committed to exploring design principles that will ensure the most responsible project can be developed.
  • Adaption:  The site can be readily rehabilitated to a state that will enhance the community and environment.
  • Start in the southeast corner of the Scott Property
  • Cross below Burma Road and Rocky Ridge Road into the provincial STAR pit property
  • Run along the south side of Burma Road, behind a landscaped berm
  • Turn south at 85th Street NW and run along the east side of the STAR pit property, behind a landscaped berm
  • Cross below 85th Street NW north of the correctional centre to the Heidelberg’s Spy Hill facilities

The conveyor system is being proposed to address local concerns about traffic and dust; however, it does come with its own potential impacts including possible restrictions to wildlife movement, vegetation and wetland loss where the footings are located and drainage impacts due to the berm location.  As part of the project development, Heidelberg will evaluate these potential impacts and develop mitigation measures which could include wetland avoidance, wildlife passage considerations and culvert placement.

The site is a significant deposit and could sustainably supply aggregates to the local market for 25 to 30 years depending on the final mining plan and market demand.
