SUCCESSFUL TESTING OF SUBMERSIBLE PUMPS TO DEWATER CENTRAL RAND BASIN
Central Rand Gold provides the following update on the Acid Mine Drainage
situation at its operations in the Central Rand Basin.
In August 2010, Central Rand Gold ordered two submersible pumps from
international technology group, Andritz Ritz, at a cost of Euro3.5 million
collectively. The two submersible pumps have the capability to dewater and to
restore the Company`s resource base in the Central Rand Basin. They also form
part of a larger proposed plan to stop, and partially treat Acid Mine Drainage
via the establishment of a submersible pump station, which would be constructed
at the South West Vertical shaft.
As part of the quality control plan, the pumps were individually tested on
Wednesday, 20 July 2011 and Friday, 22 July 2011, respectively, in a special
testing bay at the manufacturer`s factory in Schwabisch Gmund in Germany, to
ensure conformance to specifications. Representatives from Central Rand Gold as
well as the Trans Caledon Tunnel Authority ("TCTA") (appointed project managers
by the Department of Water Affairs) and BKS (consultant to TCTA) were present.
It was verified that both pumps comfortably achieved the required design
capacity to pump 1,500 kilolitres of water per hour at 43 bar pump pressure
differential. This was achieved at a pump efficiency of 81.1%.
Each of the pumping units has an overall length of 13.5 metres and a mass of 18
metric tons, and is designed to pump water from 400 metres below surface. The
pumps are constructed from a special duplex stainless steel to ensure long-term
resistance to the dilute sulphuric acid water.
The pumps will remain in Germany until such time as clarity has been obtained
with regards to the final technical solutions and project timelines. In the
event that these pumps are not utilised for the purpose of the submersible pump
station, the Company intends to sell them.
