- CSA A23.2-04 15A Petrographic Examination of Aggregates:
This examination provides identification of rock types in aggregates as well as an assessment of their mechanical and physical and chemical attributes. The examination can be used for quality control of aggregates, preliminary assessment of new or untested aggregate sources, and to identify harmful or undesirable components within an aggregate sample.
- Acid Rock Drainage/Metal Leaching (ARD/ML):
After being exposed to air and water, oxidation of metal sulphides within the aggregate or quarry rock generates acidity. ARD/ML refers to the harmful leaching of acidic fluids into water courses where this fluid may cause damage to the affected ecosystem.
- Quarry/Gravel Pit Mapping:
Mapping services by Professional Geologists from grassroots surveys to detailed structural maps; delineation of mining zones to help quarry or pit operators operate efficiently.
- Drill Material Logging:
Services include monitoring of drilling operations and logging of drill material for exploration programs or quarry operations. We have experience with various drill rigs including diamond, reverse circulation and rotary drilling.
- Equivalent Quartz Content:
Equivalent Quartz Content is a parameter used to predict drilling bit wear and when used with other mechanical rock properties such as unconfined compressive strength and Young’s modulus, can help predict drillabilty of rock material and drilling rates.
- Petrological Identification:
A study of a rock or gravel in terms of their origin and formation, mineral composition and classification. Thin sections and hand samples are used by the geologist to assess the material and report it in an easy to understand format. An in-depth report will include photographs and photomicrographs of the sample.
- Photographic Documentation:
This service is provided by a professional photographer and deals with documenting a project site or property prior to and after the project is complete. The images are presented in a bound report and signed by a Professional Engineer or Geoscientist thereby becoming a legal document associated with the project.
- CERCHAR- Rock Abrasion Index:
Due to the advanced mechanization of the methods of excavation, in particular the increasing use of tunnel boring machines in underground construction, it is necessary to know the rock abrasivity. The CERCHAR test determines the abrasivity of natural rocks, by measuring the wear on a steel cone caused by scratching a freshly broken rock surface.
