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 minimal additional laboratory preparation.
Trenching equipment uses the chain or boom with a continuous cutting chain, or the earth saw (rock saw), a rotating wheel with tungsten carbide teeth. Chain trenching is suitable for soft (free dig) oxide ores where greater depth is required. Rock saws are capable of digging in tougher ground conditions than the chain without varying trench depth.
Murchison Grade Control Pty Ltd’s two decades of experience in the grade control application of trenching machines has enabled it to provide valuable knowledge to mining companies on all aspects of this technique. We can advise on choice of services (contract, lease, or capital purchase), machine selection and options, machine preparation, operator and maintenance crew training, maintenance and repair procedures, transport & handling, operation in the grade control application and sampling techniques, spare parts inventories & acquisition and record keeping.
