VOLUME 2 • ISSUE 3 • MARCH 2013 MOVING THE DREDGE Sierra Rutile's dredge was relocated 400 metres to a new section of the Lanti deposit on the 22nd March. It was a process that involved five departments, over 100 people and more than 60 hours in planning and labour. In a Q&A, Sylvester Zoe, senior mine planning engineer, explains how it works. How do you know when to move the dredge? The Company has conducted detailed geological mapping of the Lanti deposit and we are aware of the reserve and resource of the deposit. We know how much the deposit contains and how much is mined each month. Consequently we can predict how long the dredge can continue to profitably mine the same section of the dredge lake, and when it will have to be moved. How is the dredge moved? The dredge is usually anchored in position by three ropes connected from the dredge and buried on land. The front anchor is called the headline, and two lines on the sides are called sidelines. In order to move the dredge, the headline is removed from its existing anchor position on land and buried in its new anchor position. The same is done with the two sidelines. Then we winch the dredge navigating it into its new position using a winder to pull on the headline and sidelines. If necessary, boats serve as auxiliary aid in pushing the dredge to its new location. What else has to be moved? The product line linking the dredge to the wet plant also has to be moved. The product line pipes are suspended on the pond by pontoons, and we use boats to advance them to their new position. If necessary, the pipe length can be changed by adding or removing individual pipes to obtain the desired length. How long does it take to relocate the dredge into its new position? We start at 7.30 am and it can sometimes take up to 12 hours. Which departments are involved? Moving the dredge is the work of five departmental sections – Mine Planning, Land Support, Dredge Operations, Mining Services and Survey. How many times will the dredge be relocated in 2013? Three times.
