Grade Control Trenching
Ditch Witch® Trenching Equipment for Open Pit Grade Control was pioneered by the Company's Director Warwick Archer and Geologist Adrian Griffin at Marvel Loch Gold Mine Western Australia in 1984.The success of this technique led to widespread use in the Goldfields of Western Australia and Northern Territory. Murchison Grade Control Pty Ltd was founded in 1988 to provide these services as a dedicated Contractor.
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.
Trenching equipment uses the Chain or Boom with a continuous cutting chain, or the Earth Saw, a rotating wheel with tungsten carbide teeth. Chain trenching is suitable for soft (free dig) oxide ores where greater depth is required. Earth Saws are capable of digging in tougher ground conditions than the chain without varying trench depth.
MGC has provided these services to over 100 operating Gold Mines in Western Australia and the Northern Territory. In 1998 the technique was adopted for grade control at Bulong Nickel's new lateritic Nickel deposit in the Kalgoorlie region of Western Australia. In 1999 MGC commissioned a Ditch Witch Earth Saw for grade control at Bogoso Gold Mine in Ghana West Africa. This is the first occasion this equipment has been used for grade control on the African continent.
Consulting Services for Grade Control Trenching & Earth Sawing.
Murchison Grade Control Pty Ltds two decades 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, record keeping.
MGC recently provided these services to Equigold Ltd new mine at Bonikro in Cote D'Ivoire (Ivory Coast) West Africa. This is an important project both for Equigold and Cote D'Ivoire being the first major large scale gold operation in the country. Due to be commissioned in April 2008, the 1.5 MPTA CIL plant is providing dozens of jobs for local Ivorians from plant operation, repairs and maintenance trades to mining professionals. Equigold are using a Ditch Witch Model RT115 Earth Saw for grade control in the laterites and oxides. MGC provided on-site instruction in Operator and maintenance training, spare parts contingencies, manuals and sampling techniques.

Murchison Grade Control Pty Ltd has successfully provided services to small and large civil construction, infrastructure and Defence and major Mining Projects.
Wattle Point Wind Farm Project.
Located at the southern end of Yorke Peninsula, this important regional project will deliver 98 MW into the local grid and is the largest windfarm project so far completed in South Australia. Underground Installations Pty Ltd completed extensive trenching works for the electrical contractor United KG for installation of 22kv underground cables. Local ground conditions ranged from sand to broken boulders and sheet limestone over the full depth of the trench. UGI used Ditch Witch Model 8020 Turbo Heavy Duty Rock Saws cutting 150 mm wide by 1000mm deep and achieved production rates of up to 260 metres per day in the hardest conditions.
Owned by Meridian Energy, the Wattle Point Wind Farm is due to come on line in June 2005.
Nullarbor Signal Upgrade Project.
As part of a $16M upgrade of the rail line between Kalgoorlie and Adelaide. Murchison Grade Control Pty Ltd was awarded the contract by Rail Services Australia to install signal cables from Kalgoorlie (Parkeston Siding) to Cook. Following successful completion MGC tendered for and was awarded Stage 2 Fisher to Hesso Sidings finishing near Port Augusta in South Australia. Conducted across 2000km of very remote country, work included 41 Sidings, 27 under track bores and 14,000 metres of trenching. Terrain varied from rough unmade limestone tracks to sandhill country where progress was often limited to 10km per hour or less. The extreme remoteness meant all supplies had to be carried including fuel, tyres, food, water and repair facilities and spares.
Travel to and from work sites involved up to 240km daily before commencing work. The MGC team and Rail Services Australia staff worked together as a team to complete the Project in October 1999, almost a month ahead of schedule, without disruption to rail traffic and nil incident record. Equipment used included two International 8 X 4 Trucks, Toyota Landcruiser field vehicle, light Aircraft, heavy duty tandem trailers, a Ditch Witch Model 7610 Earth Saw with Backhoe attachment, a John Deere Backhoe/F.E.L., McLaughlin Horizontal Borer and Ditch Witch Subsite electronic cable locator.
Geraldton to Windamurra Gas Pipeline
Work commenced early in 1999 on the 350km HP Gas Pipeline to Vanadium Australia Ltd's new mine at Windamurra near of Mount Magnet in Western Australia's Murchison Region. Murchison Grade Control Pty Ltd used a Vermeer T850 Rock Saw to cut significant sections of the hard cemented cap rock prevalent in that area. The project was managed by Clough Lucas Joint Venture and MGC is proud to have contributed to this important regional project.
Bulong Nickel Project
The Bulong Nickel Project has a Nickel (Ni) resource that is contained within the profile of weathered ultramafic (greenstone) rocks called laterites. These laterites are relatively flat laying and each profile bears its own unique physical and chemical characteristics. Bulong Nickel approached Murchison Grade Control Pty Ltd to provide a suitable Trenching Machine to cut 2 metres deep to sample the full bench height. MGC supplied a new Ditch Witch Model 8020 Turbo fully hydraulic Trencher with a 2m Chain Attachment and equipped with enclosed air conditioned cab, high flotation foam filled tyres, skilled Operator , on-site field vehicle and workshop.
