Reclamation Soils Model Geodatabase

This project worked to develop a geodatabase Reclamation Soils Model for Horizon Oil Sands Facility site covering both GIS and soil auger program to facilitate the production of year-end reports and to streamline the access to information for soil analyses data and audit information. By comparing available and required soil volumes, the model will inform strategic decisions to meet long-term reclamation objectives aligned with regulatory approvals. This tool is essential for ensuring sustainable land restoration as mining operations progress toward their projected end in 2050.

Version 1 of the reclamation model was completed. The Horizon Soils Model is a dynamic geospatial database developed to support reclamation planning at the Horizon Oil Sands Facility in northern Alberta. It integrates spatial and descriptive data on upland soil, subsoil, and organic cover materials across the lease to estimate available reclamation resources. Updated annually with field survey and sampling data, the model enables continuous assessment of soil material balances required for mine closure. As an integral part of the planning process, it supports long-term operational and budgetary forecasting, ensuring that end-of-life reclamation requirements are met. The model is continuously improved with new data and is planned to transition from ArcGIS® to MineSight software to enhance accessibility and planning efficiency, alongside the development of a user guide and a professional QA/QC review.
