:: DRA Makes Tracks in Canada

Two projects are currently under way in Canada which have proved the abilities of DRA Mineral Projects to meet and exceed client requirements.

The De Beers Snap Lake Diamond Project is nearing completion as the modular recovery plant designed and built by DRA is undergoing C1 and C2 commissioning on site. The project proved a challenging one for the company as it involved the building and delivery of a 30 module plant to the Snap Lake site located 220kms north east of Yellowknife in Canada’s Northwest Territories, accessible only during a short period from February to March over what is known as the Winter Road, built over frozen ground and lakes.

The recovery plant, which was built and tested in South Africa left the country in November 2006 and reached the site in February. The lead engineer on the project oversaw the commissioning by Canadian engineers and the plant is expected to come on line by the end of July.

The recovery plant features a unique modular design which not only facilitated its transportation to the site but also made assembling it easier. The system, which when assembled measures 30m in height, consists of a total of 30 modules - 18 for the plant itself as well as an additional 12 for stairways and ancillary use. The 3-stream plant will process fines, coarse and middles material and incorporates primary and secondary x-ray as well as Raven laser sorting systems. The plant also comprises a pneumatic feed system, a vacuum spillage system; dust extraction and pressurisation plant, a canning system and safe.

A sister project to Snap Lake is De Beers Victor Mine Project which also saw the design and manufacture of a similar modular recovery system with the addition of a bulk sampling system. While the lessons learned from Snap Lake stood DRA in good stead, the client moved the schedule for delivery up by a year which placed additional pressure on the team, to complete the project on time in order to make the 2007 Winter Road. Needless to say that the company managed to meet the new deadline, delivering the plant in the same shipment as the one destined for Snap Lake. The reassembly of the plant is expected to be completed by November 2007 and to come on line by December

The Victor Project is a kimberlite dyke located in the James Bay Lowlands 90km west of the Attawapiskat community in Northern Ontario. This is the first diamond mine for the Canadian province and only the second in the country for De Beers. The mine itself has an expected life span of 12 years and is expected to process 2,5 million tons of kimberlite per year.
