What is grade control?
Grade control is a method of checking the grade (quality) of ore on a mine site by drilling holes in a relatively tight pattern, garnering samples, and testing them. The information garnered by grade control in the form of samples can help to define the boundaries of where workers should mine by how profitable it will be and how to prevent important mineral from being lost.
Innovations in grade control
Grade control was traditionally a process overseen by geologists, but with the development of technological grade control systems that can guide earthmoving machinery including crawler dozers and motor graders on the desired depth, slope, and alignments, has been improved in productivity and cost benefit.
Benefits of grade control
Grade control systems determine where mining will be profitable, ensure important material will not be lost, and do it quickly and cheaply, compared to traditional methods.

Grade control trenching
Murchison Grade Control uses Ditch Witch® trenching equipment for open pit grade control. This grade control technique was pioneered by Company's Director Warwick Archer and Geologist Adrian Griffin. As the pioneering company in this grade control method, we are equipped and experienced to complete quality grade control work.
The Ditch Witch® sample provides an excellent high density continuous sample across strike enhancing visual control and sub-surface exposure for mapping. Collection of the finely ground, well mixed sample is simple, fast and labour efficient and requires little additional laboratory preparation.
Additional services
MGC’s experience with trenching equipment for grade control enables us to provide additional services for a range of projects including the installation of underground utilities, pipeline construction, airport lighting, and communications installation, especially in remote areas.
