Murchison Grade Control (MGC) Civil & Mining provides grade control services to mine sites across Australia and beyond. With over 30 years of experience improving the productivity of mine sites, and the pioneering of Ditch Witch® trenching equipment for open pit grade control under our belts, we are Australia’s trusted grade control supplier in the civil and commercial sectors. Murchison Grade Control Pty Ltd can quote on large and small projects, supply dedicated site services for customers requiring continuous availability or provide prompt mobilisation as required to meet your requirements.
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.
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.

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.
