FOR IMMEDIATE RELEASE
March 22, 2011

New Richmond, WI - Liquid Waste Technology (LWT) has delivered and installed its new remote controlled diesel powered Mud Cat™ dredge to the Minera Esperanza mine site in Chile. The new remotely operated dredge has stainless steel construction, an extreme duty Toyo™ mining pump and reliable Cat™ 78 HP diesel engine for handling tailings in mining ponds.

The radio remote operated dredge is all stainless steel construction for long life. LWT equipped the dredge with exclusive automation options to improve productivity and ease of use, such as Bottom Sense™ and Auto-Sense™. Using Bottom Sense™, dredge's auger-head will automatically raise and lower to follow the bottom's contour eliminating the risk of damage to the pond liner. The Auto Sense™ feature increases operator productivity by allowing the dredge to stop the dredge's forward movement automatically and return to the point of origin to await the next command. The dredge was equipped with LWT's Solids Sense™ feature, which adjusts the speed of the dredge to optimize a predetermined percentage of solids established by the operator. This feature assists the dredge operator to maintain maximum production of solids at a specified flow rate and minimizes the labor required to operate the dredge. It is ideal for both de-watering and continuous process systems. LWT provides start-up field training to ensure continued quality performance and safety. During the commissioning, a series of test runs are initiated to fine-tune the dredge's performance and to adjust the automated system to match the customer's requirements.
