INNOVATIVE mineral processing equipment house, Gekko Systems , has received a $1.2 million order from UK-based Celtic Resources Plc to purchase a Gekko Gravity and Intensive Leach Plant including, the largest model InLine Leach Reactor, two InLine Pressure Jigs and ancillary equipment.
The equipment is destined for the Nezhdaninskoye mining project in eastern Russia. Nezhdaninskoye is Russia's second largest gold mine with Measured, Indicated and Inferred Resources (Western JORC standards) of 13.9 million ounces of gold from only 37 of the 119 ore bodies and 100 million ounces silver (Russian Classified).
Test work performed in England, Australia and Russia identified that the unique Gekko technology has the potential to provide superior results to any other technology in the world. Furthermore, the cost effectiveness of the technology and environmental advantages will significantly lower the overall installation costs to Celtic.
"We do not believe that it is appropriate anymore for CIP/CIL circuits - or whole ore leaching - to be regarded as the standard option for gold plant design. In many circumstances using an alternative of gravity and/or flotation coupled with intensive leach provides the same or higher recovery at significantly lower environmental, capital risk and operating costs," said Gekko Systems CEO Elizabeth Lewis-Gray.
"We believe our technology offers the potential for a step change in processing design for the gold industry - the Nezhdaninskoye process flow sheet is a perfect example."
Engineering firm Lycopodium has worked with Gekko Systems and Celtic Resources to design a flowsheet that will include gravity concentration and flotation to recover a gold/silver concentrate which will be treated using intensive cyanidation.
The goods will be shipped to the port of Vladivostok, Russia early 2003 and then trucked over ice to the mining site. Members of the Gekko Technical and Laboratory Team, Nigel Grigg, Nick Katsikaros and Suzanne Dorey have been closely involved with Celtic and their engineering representative for more than 18 months assisting with intensive test and design work.
Celtic Resources will list on the AIM (Alternative Investment Market) market in London next week at an expected capitalisation of $100m. Celtic also owns the Kazakhstan based Suzdal Gold Mine, which produced some 43,000oz last year.
Gekko Systems and its design team have won awards for Innovation (Cisco Small Business Award for Innovation - Victoria) and Design (Clunies Ross Science Award). Deloitte Touche Tohmatsu listed Gekko Systems in 2002 as Australia's 20th Fastest Technology Growth Company.
Inline Pressure Jig
The InLine Pressure Jig (IPJ) is a high yield, high recovery gravity separation device. It has been successfully installed in both alluvial and hard rock applications. The IPJ is currently being operated worldwide to recover free gold, sulphides, native copper, native silver, tin/tantalum, diamonds and garnet. Installations are also planned for coal, lead remediation, magnetite, mineral sands, and iron ore recovery.
In Line Leach Reactor
The InLine Leach Reactor (ILR) has been used to increase recoveries of both free gold and sulphide related gold. In all installations of the ILR to date significant increases in total recoveries have been achieved. This reflects the ILR's very fast leach kinetics and capacity to leach coarse and high grade gold concentrates.
Gekko Systems Pty Ltd was created by Sandy Gray and his wife and business partner Elizabeth Lewis-Gray in 1996. They had a big vision, modeling themselves on the giant Caterpillar - " That was our inspiration. That's why we chose an animal name."
Gekko established its factory and office in Ballarat in 1998 and now, to meet the explosive worldwide demand, has located offices in Johannesburg and Vancouver.
Today Gekko mineral recovery systems are helping to improve the environmental and economic performance of mines operated by some of the biggest names in the business including De Beers, Anglo-Gold, RTZ, MIM and Placer Dome. They provide gravity separation and intensive leach systems in gold, sulphides, copper, diamonds, garnets, slags, tantalum and tin mines.
While minimising environmental impact has been a critical focus, Sandy also acknowledges that working as a mine manager for fifteen years has inspired him to create efficient, quality solutions for mining sites.
He laughingly attributes his unique ability and incredible confidence " to an absolute belief in my own design capabilities".
